Description

  The present invention relates to a heating system and a heating method including a radiant heating device that radiates heat energy of a heat transfer medium.

  Heating devices that warm the partitioned space are classified into various types of heating devices, for example, forced convection heating devices, radiant heating devices, etc., according to the heat transfer mode. A forced convection heating device is a heating device that warms the air and forcibly blows the heated air to warm the space, like an air conditioner. A radiant heating device uses radiation like a floor heating. It is a heating device that radiates heat energy.

  For example, in a forced convection heating device or a radiant heating device, a heat transfer medium heated by one heat source is acquired, and after performing a heat transfer function according to each method as described above, a heat transfer medium whose temperature has decreased is obtained. It is returned to the heat source. Usually, a forced convection heating device and a radiant heating device each constitute a circulation system with one heat source, and one circulation system (one heating device) is arranged for each space to be heated.

  In Patent Document 1, a floor heating mat as a radiant heating device is cascade-connected downstream of a fan convector as a forced convection heating device, and heat exchange with a heat transfer medium is continuously performed in both devices. A technique for effectively using the heat energy of a heat transfer medium is disclosed.

Japanese Patent Laid-Open No. 11-83044

  In the technique of Patent Document 1 described above, a forced convection heating device is disposed upstream as a main heating device, and the radiant heating device uses a heat transfer medium in which heat energy is consumed by the forced convection heating device. ing. Such a forced convection heating device can take up a large amount of heat energy per unit time, so that the space to be heated can be quickly heated, but the house dust is wound up by strong air flow, etc. The temperature distribution in the target space becomes uneven. Therefore, there have been problems such as the temperature of the floor or the like where there are many opportunities to come into direct contact with people remain low, or that some areas are overheated as the temperature of the space rises.

  Further, in the technology of Patent Document 1, since the consumption and fluctuation of the thermal energy in the upstream forced convection heating apparatus are large, the temperature control is performed on the heat transfer medium having a large inflowing temperature in the downstream radiation heating apparatus. This makes it difficult to achieve a uniform temperature distribution. Moreover, even if the temperature can be controlled, the radiant heating device with poor responsiveness cannot fully release the heat energy remaining in the heat transfer medium, and the heat transfer medium is returned to the heat source while the temperature is still high. As a result, the heat transfer efficiency from the heat source has been reduced.

  In addition, despite the fact that the radiant heating device is cascade-connected downstream, there is a case where the radiant heating device does not reach the heating target space due to the lack of quick response.

  In view of such a problem, the present invention realizes a uniform and comfortable temperature distribution by the radiant heating device, and can sufficiently discharge the heat energy remaining in the heat transfer medium downstream thereof. It aims to provide a system and heating method.

In order to solve the above problems, a heating system of the present invention includes a heat source that heats a heat transfer medium, a radiation heating device that is arranged downstream of the heat source and radiates heat energy of the heated heat transfer medium, and a radiation Forced convection heating system, which is arranged downstream of the heating system, warms the air by the heat transfer medium after the heat energy is radiated, forcibly releases the heated air to the outside , and returns the heat transfer medium to the heat source The forced convection heating device is provided with an intake port, an exhaust port, a heat exchange unit that exchanges heat between the air and the heat transfer medium, and air is sucked from the intake port and passed through the heat exchange unit. A forced fan that blows air through the exhaust port, a medium temperature detection unit that detects the temperature of the heat transfer medium flowing into the heat exchange unit, and an indoor temperature detection unit that detects the temperature of the air flowing in from the intake port, Either the temperature of the heat transfer medium or the temperature of the air And an air flow rate control unit that controls the air flow rate of air that has been heat-exchanged through a forced fan according to both, the forced convection heating device is embedded in a wall that divides a space that discharges warm air, The space-side surface that discharges the warmed air is covered with a plurality of decorative boards formed continuously with the baseboard of the wall, and the forced convection heating device is formed by a gap provided between the plurality of decorative boards, It characterized that you form a flow path of the blown air from the flow path and an exhaust port for directing the air to the intake port.

The forced convection heating device may release air into a space where the radiation heating device radiates heat energy and a different space partitioned by a partition wall.

  The forced convection heating device may release air into the same space as the space where the radiant heating device radiates heat energy.

In order to solve the above problems, the heating method of the present invention uses a heat source, a radiant heating device arranged downstream of the heat source, and a forced convection heating device arranged downstream of the radiant heating device. The forced convection heating device includes an intake port, an exhaust port, a heat exchange unit, a forced fan, a medium temperature detection unit, an indoor temperature detection unit, and an air flow rate control unit. The forced convection heating device is embedded in a wall that divides a space that emits warm air, and the surface on the space side that emits warm air has a plurality of makeups formed continuously with the baseboard of the wall. The forced convection heating device is covered with a plate, and a flow path for guiding air to the intake port and a flow path of air blown from the exhaust port are formed by a gap provided between the plurality of decorative plates, There was heated heat transfer medium, and radiating heat energy of the heat transfer medium radiant heating system is heated, In the convection heating system, the forced fan sucks air from the intake port, passes through the heat exchange unit, blows air through the exhaust port, and the heat exchange unit exchanges heat between the air and the heat transfer medium. The temperature detection unit detects the temperature of the heat transfer medium flowing into the heat exchange unit, the indoor temperature detection unit detects the temperature of the air flowing in from the intake port, and the air flow rate control unit detects the detected heat transfer medium Depending on one or both of the temperature of the air and the temperature of the air, the air is exchanged by the heat transfer medium after the radiant heating device radiates the heat energy by controlling the amount of air exchanged through the forced fan. Warm, warm air is forcibly discharged outside , and the heat transfer medium is returned to the heat source.

In the present specification and drawings, elements having substantially the same function and configuration are denoted by the same reference numerals, and redundant description is omitted, and elements not directly related to the present invention are not illustrated. To do.

(Heating system 100)
FIG. 1 is a functional block diagram illustrating a schematic configuration of the heating system 100. As shown in FIG. 1, the heating system 100 is used in an indoor room, for example, a partitioned space, and includes a heat source 110, a floor heating 120 as a radiant heating device, and a forced convection heating device. And a warm air fan 130. In the heating system 100, the heat source 110, the floor heating 120, and the hot air fan 130 are cascade-connected in that order, and a heat transfer medium (heating medium) circulates between the devices as indicated by arrows. The heating system 100 of the present embodiment mainly corresponds to a low-temperature system that circulates a heat transfer medium of 60 ° C. or less.

  For example, the heat source 110 heats the heat transfer medium through a heating unit such as gas or electricity, and sends the heated heat transfer medium to the floor heating 120 through a pump or the like (not shown). The floor heating 120 is disposed downstream of the heat source 110 and radiates heat energy of the heat transfer medium heated by the heat source 110 by radiation. The warm air fan 130 is arranged downstream of the floor heating 120, warms the nearby air with the heat transfer medium after the thermal energy is radiated by the floor heating 120, and forcibly releases the warmed air. Then, the heat transfer medium from which the thermal energy has been released is returned to the heat source 110. In the description of the present embodiment, the temperature of the heat transfer medium and the magnitude of the heat energy of the heat transfer medium are properly used depending on the content of the description, but they are treated in the same meaning. Therefore, when the temperature of the heat transfer medium is high, the heat energy is large, and when the temperature of the heat transfer medium is low, the heat energy is small. Hereinafter, schematic configurations of the floor heating 120 and the warm air fan 130 which are components of the heating system 100 will be described.

(Floor heating 120)
FIG. 2 is an explanatory diagram showing a schematic configuration of the floor heating 120. The floor heating 120 is embedded in a floor 122 which is a partition wall vertically below among partition walls surrounding a space (room) to be heated. Further, the floor heating 120 is formed by meandering a resin pipe 124 as shown in FIG. 2, for example, and heat is transferred through the pipe 124 as shown by the black arrows in FIG. As the medium circulates, radiant heat is released from the tube 124 as indicated by the white arrow. In this way, highly comfortable heating is realized in the space to be heated.

  Here, the floor heating 120 is described as an example of the radiant heating device. However, the radiant heating device is not limited to the floor heating 120, and for example, by exposing the pipe 124 to a space to be heated. A radiator or the like that generates natural convection in addition to radiation can be used.

(Hot air fan 130)
FIG. 3 is an explanatory diagram showing a schematic configuration of the hot air fan 130. The hot air fan 130 includes an intake port 150, an exhaust port 152, a heat exchange unit 154, a forced fan 156, a medium temperature detection unit 158, an indoor temperature detection unit 160, and an air flow rate control unit 162. Composed.

  The air sucked from the air inlet 150 is heat-exchanged with the heat transfer medium flowing in from the floor heating 120 in the heat exchanging unit 154 in which a plurality of fins are separated from each other, and the temperature is raised. At this time, the forced fan 156 is composed of, for example, a propeller fan, sucks air from the intake port 150, passes through the heat exchange unit 154, contributes to heat exchange with the heat exchange unit 154, and warms air to the exhaust port The air is pushed out to 152 and blown from the exhaust port 152.

  Here, since the heat exchange unit 154 forms a part of the pipe 164 through which the heat transfer medium flows, the pressure loss can be minimized, so even if it is connected in series with the floor heating 120, heating is performed. The effect of pressure loss on the system 100 can be reduced.

  The medium temperature detection unit 158 is provided on the upstream side of the heat exchange unit 154 and detects the temperature of the heat transfer medium flowing into the heat exchange unit 154. The indoor temperature detection unit 160 is provided on the downstream side of the intake port 150 and detects the temperature of the air flowing from the intake port 150. The air flow control unit 162 then warms through the forced fan 156 according to one or both of the temperature of the heat transfer medium detected by the medium temperature detection unit 158 and the temperature of the air detected by the room temperature detection unit 160. Control the amount of air flow.

  For example, when the air volume control unit 162 detects that the temperature of the heat transfer medium has become equal to or higher than a predetermined first threshold (for example, 40 ° C.) by the medium temperature detection unit 158, that is, the floor heating 120 transfers heat. When it is detected that the medium starts to flow, the operation of the forced fan 156 is started. Further, when it is detected that the temperature of the heat transfer medium is lower than a predetermined second threshold (for example, 30 ° C.), the operation of the forced fan 156 is stopped because the flow of the heat transfer medium is stopped. Further, after the forced fan 156 starts operating, the operation of the forced fan 156 is stopped when the air temperature detected by the room temperature detection unit 160 becomes a predetermined threshold (for example, 20 ° C.) or more. Also good. Further, the operation of the forced fan 156 may be stopped when a predetermined time (for example, 1 hour) has elapsed since the forced fan 156 started operating. Furthermore, it is possible to sufficiently release the heat energy of the heat transfer medium by controlling the blown amount (rotation speed) of the forced fan 156 according to the temperature of the heat transfer medium.

  As described above, the medium temperature detection unit 158, the room temperature detection unit 160, and the air flow control unit 162 allow the user to operate the floor heating 120 without operating the operation of the hot air fan 130 through a dedicated remote controller or the like. Accordingly, it is possible to automatically control the air flow rate. Therefore, it is possible to reduce the initial cost (initial cost) for installing the equipment by the amount that it is not necessary to provide a dedicated remote controller.

  As described above, in the present embodiment, the floor heating 120 and the hot air fan 130 are cascade-connected such as the floor heating 120 upstream and the hot air fan 130 downstream, so that the heat energy of the heat transfer medium is increased. It is possible to improve the amount of heat that can be sufficiently discharged and extracted by the floor heating 120 and the hot air fan 130 with respect to the system efficiency of the heat source 110, that is, the heat input of the entire heating system 100. The necessity of cascade connection is described below.

  In the case of a latent heat recovery heat source device that can recover the latent heat of water vapor contained in the combustion exhaust gas, the lower the temperature of the water or hot water flowing into the secondary heat exchanger, the higher the amount of water vapor that will condense. Can be taken away. Therefore, in order to improve the system efficiency, it is necessary to cascade the floor heating 120 and the hot air fan 130 and lower the temperature of the heat transfer medium by sufficiently releasing the heat energy of the heat transfer medium. .

  In particular, in this embodiment, the floor heating 120 is arranged upstream and the hot air fan 130 is arranged downstream, so that the thermal energy remaining in the heat transfer medium by the hot air fan 130 while the floor heating 120 is the main heating. Is effectively released.

  More specifically, the floor heating 120 warms the space to be heated by radiation, and therefore is less responsive to the temperature rise in the heating target than the forced convection heating device, but does not wind up house dust due to strong air blowing. In addition, the temperature distribution in the object to be heated becomes uniform due to radiation, so that the human body in the space is not exposed to the temperature distribution, and there is warmth due to contact heat conduction from the warm floor surface, etc. Is excellent. Moreover, since it is a radiation type, a noise does not arise compared with a forced convection type heating apparatus. Further, unlike the forced convection heating device, it is possible to keep the entire space to be heated at a comfortable temperature without overheating part of the region.

  Further, since the floor heating 120 consumes less heat energy and its fluctuation during normal operation, it is easy to assume available heat energy in the subsequent hot air fan 130, and stable control by the hot air fan 130 can be realized. Furthermore, the warm air fan 130 can change the consumption of heat energy relatively easily by the output of the fan, and in some cases can release a large amount of heat energy, so it can be consumed by the floor heating 120. It is possible to sufficiently release the heat energy that was not present.

  Further, in the hot air fan 130, forced convection is generated by the forced fan 156, so even if the temperature of the heat transfer medium is relatively lowered by the floor heating 120, the heat energy from the heat transfer medium is increased. Can be released, and the temperature can be lowered. Here, although the warm air fan 130 releases thermal energy by forced convection, the warm air fan 130 is only an auxiliary role of the floor heating 120, so its capacity is small and no noise is generated. There is little influence on the temperature distribution in the heating target.

  Therefore, it is possible to sufficiently release the heat energy remaining in the heat transfer medium in the hot air fan 130 downstream thereof while realizing a uniform and comfortable temperature distribution by the floor heating 120.

(Positional relationship between floor heating 120 and hot air fan 130)
As described above, when focusing on the consumption of heat energy, the floor heating 120 and the hot air fan 130 may be cascaded, and the heat energy may be consumed by each to lower the temperature of the heat transfer medium. The positional relationship between the heating 120 and the hot air fan 130 is not questioned. However, from the viewpoint of quickly heating the space to be heated, it is preferable that the warm air fan 130 and the floor heating 120 simultaneously heat the same space with the other partition walls, that is, the space to be heated simultaneously. .

  As described above, the floor heating 120 is excellent in comfort because there is no hoisting of house dust due to strong air blowing, and heat energy is released by radiation so that the temperature distribution in the heating target becomes uniform. On the other hand, the quick response to the temperature rise in the heating target is relatively low compared to the forced convection heating device. Therefore, a warm air fan 130 is provided to gently assist the temperature rise at the start of heating of the floor heating 120. Although the hot air fan 130 has a small capacity, the warm air is directly discharged to the space to be heated by forced convection, so that the convenience and comfort of the floor heating 120 are not impaired. Rapid start-up can be promoted. Further, as described above, since the hot air fan 130 is an auxiliary role of the floor heating 120, problems such as house dust hoisting, noise, and influence on the temperature distribution do not occur.

(Other positional relationship between floor heating 120 and hot air fan 130)
Moreover, the warm air fan 130 can also be arrange | positioned in the different space partitioned off at least by the boundary with the floor heating 120, and the space different from the floor heating 120 can also be warmed by the warm air fan 130.

  Usually, the heating system 100 consumes the heat transfer medium heated by one heat source by one heating device. Therefore, when there are a plurality of places or rooms to be heated, it is necessary to install an installation work or a dedicated controller in order to arrange an individual circulation system for each, which may increase the construction cost. In addition, when heating a narrow space such as a toilet, washroom, or corridor, although it is cold in winter and heating is required, heating with high heat dissipation capability is not necessary, and only one circulation system is provided for that purpose. There was a fact that it was not cost-effective.

  Here, for example, the warm air fan 130 cascade-connected to the floor heating 120 is independently arranged in another room. Since the hot air fan 130 uses thermal energy that cannot be consumed by the floor heating 120, the hot air fan 130 is efficient, and it is not necessary to newly increase the number of systems, so that the construction cost can be minimized. In addition, since the medium temperature detection unit 158, the indoor temperature detection unit 160, and the air volume control unit 162 in the hot air fan 130 operate independently of the floor heating 120, temperature control is appropriately performed even in other rooms. can do.

  Thus, while the floor heating 120 is being used in another room, the remaining heat energy is used to preheat non-rooms such as toilets, washrooms, and corridors, so the user can Even if it moves to such a space, there is little temperature difference and it can spend comfortably. Moreover, it becomes possible to raise the base temperature of the whole indoor by each heating a some non-living room auxiliary.

  In general, non-living rooms such as toilets, washrooms, and corridors often do not have a space for a heating device. However, the hot air fan 130 has a small capacity and is compact and can be connected to other devices. However, it can be installed relatively easily because only the heat transfer medium is sent and received.

  Further, a heat storage material is applied to the main body of the hot air fan 130, and the heat energy of the heat transfer medium flowing from the floor heating 120 is stored separately in the heat storage material, and the heat energy for the stored heat is also stored after the floor heating 120 is stopped at night or the like. Is discharged from the warm air fan 130, so that non-residential rooms such as toilets, washrooms, and corridors can be warmed over the night.

(Installation position of hot air fan 130)
By the way, the floor heating 120 has the main pipe 124 embedded in the floor surface, so that the user does not make the user aware of the floor heating 120 as an apparatus in appearance and the temperature distribution in the space to be heated. Because heat energy is released so that the temperature becomes uniform, it is difficult to be conscious of it as a heating source. On the other hand, general forced convection heating devices such as fan heaters and floor-exposed type fan convectors have a large casing and require air intake and exhaust ports. Was partly occupied. Further, the wall-mounted type or ceiling-mounted exposed type fan convector occupies a space that is relatively close to the ceiling and does not interfere with furniture in the room. Attaching the forced convection heating device at such a position is not preferable in appearance, and there is a problem that the room is felt narrow. In the present embodiment, the hot air fan 130 corresponding to the forced convection heating device is positioned as an auxiliary role of the floor heating 120, is configured to be relatively small, and the space to be heated is embedded in a partition wall, The exposure of the main body of the wind fan 130 is avoided.

  The hot air fan 130 requires the air intake port 150 and the air exhaust port 152, but is formed continuously or integrally with a part (here, a baseboard) constituting the room as shown below. Therefore, the appearance is not made to be conscious of the user.

  FIG. 4 is a perspective view showing a state in which the warm air fan 130 is installed in the room. Here, the hot air fan 130 is formed in a size that can be accommodated in a hollow partition wall, and the air intake port 150 and the exhaust port 152 of the hot air fan 130 are directed indoors, as indicated by white arrows in FIG. The whole is embedded in the wall 170. Then, the front surfaces (interior side surfaces) of the intake ports 150 and the exhaust ports 152 are covered with a decorative plate 172. The decorative board 172 is formed continuously with the baseboard 180.

  Here, the baseboard 180 is a plate that is attached to the lowermost part of the wall 170 at the joint between the wall 170 and the floor 122 and extends horizontally along the boundary between the wall 170 and the floor 122. It is provided for the purpose of clamping or buffering contact with a vacuum cleaner or the like. The baseboard 180 has a first baseboard 180a fixed to the wall 170 and having a relatively large area, and a second baseboard 180b whose lower part is in contact with the floor 122 and partially covered by the first baseboard 180a. It is comprised including. In this way, the baseboard 180 is divided into two members (first baseboard 180a and second baseboard 180b), and a gap is provided between them, so that the structure such as the wall 170 and the floor 122 deteriorates over time. It absorbs the displacement of the relative position due to the expansion of air temperature, temperature change and so on.

  Here, since the warm air fan 130 is embedded in the hollow partition wall, the piping connection with the floor heating 120 is facilitated. In addition, considering the dimensions of the main body so that it is suitable for general shaft construction methods, the length in the width direction is either between the structural column and the intermediate column, between the intermediate column and the intermediate column, and between the intermediate column and the structural column. By designing to fit properly, versatility can be improved. Furthermore, by designing the pressure loss of the heat transfer medium in the hot air fan 130 to be small, a plurality of hot air fans 130 can be cascade-connected to one circulation system, and in this case, the heat transfer medium returned to the heat source 110 It is possible to further reduce the temperature of the. Conventionally, for example, forced convection heating devices such as wall-mounted and ceiling-suspended-exposed fan convectors have to be installed at a position relatively close to the ceiling, and the warmed air is at the bottom of the room (a space where people are However, since the warm air fan 130 of this embodiment can blow the warmed air directly to the vicinity of the floor 122, the heating effect in the lower part of the room can be enhanced.

  FIG. 5 is a cross-sectional view taken along the line AA in FIG. 4 for explaining the positional relationship between the decorative board 172 and the baseboard 180. As described above, the decorative plate 172 that covers the front surface of the hot air fan 130 is disposed on a portion of the wall 170 in which the hot air fan 130 is embedded and continuous with the baseboard 180. The decorative board 172 is compared with the first decorative board 172a and the second decorative board 180b that have the same cross-sectional position as the first baseboard 180a of the baseboard 180, and the second decorative board 172b that recedes to the wall 170 side. It consists of.

  Thus, by disposing the second decorative plate 172b with respect to the first decorative plate 172a, the air gap 174 is provided between the first decorative plate 172a and the second decorative plate 172b, and the air intake port 150 A flow path for guiding air to the air and a flow path for air blown from the exhaust port 152 are formed. Here, the gap 174 is formed by retracting the second decorative plate 172b, but the gap 174 may be formed by displacing the first decorative plate 172a to the space side with respect to the second decorative plate 172b. Moreover, you may form the space | gap 174 by displacing the 1st decorative board 172a vertically upwards with the 1st baseboard board 180a.

  By providing such a gap 174 and increasing the flow area of the inflow and outflow of air from the hot air fan 130, the pressure loss can be reduced. Therefore, a low-power fan is used as the forced fan 156. It becomes possible. In addition, since the air flow rate can be reduced, noise due to inflow and outflow of air can also be reduced.

  With the above configuration, the decorative plate 172 of the hot air fan 130 can be viewed integrally with the baseboard 180 in appearance, and the user does not need to be aware of the hot air fan 130 there. Further, although the second decorative plate 172b is retracted with respect to the first decorative plate 172a, even if the user observes the part from above in the room, the second decorative plate 172b and the second baseboard 180b. Are deeper than the first decorative board 172a and the first baseboard board 180a, it is difficult to be aware of the depth difference between the second decorative board 172b and the second baseboard board 180b, and the gap 174 feels uncomfortable. Nor. In addition, the space of the room can be used effectively, and the room is unlikely to appear narrow.

(Other examples of hot air fans)
In the above-described embodiment, the propeller fan is used as the forced fan 156. However, a forced fan 256 using a sirocco fan can be used instead of the propeller fan.

  FIG. 6 is an explanatory view showing another example of the warm air fan. Referring to FIG. 6, the hot air fan 230 includes an intake port 150, an exhaust port 152, a heat exchange unit 154, a forced fan 256, a medium temperature detection unit 158, an indoor temperature detection unit 160, and an air flow control. Part 162. Among these, the intake port 150, the exhaust port 152, the heat exchange unit 154, the medium temperature detection unit 158, the indoor temperature detection unit 160, and the air flow rate control unit 162 of the hot air fan 130 already described as the constituent elements. Means that the functions are substantially the same, so that the duplicated explanation is omitted. Here, the forced fan 256 having a different configuration will be mainly described.

  As shown in FIG. 6, the air sucked from the intake port 150 by the forced fan 256 travels vertically upward once through the partition wall 264 and reaches the heat exchanging unit 154 through the forced fan 256. And in the heat exchange part 154, it heat-exchanges with the heat-transfer medium which flowed in from the floor heating 120, and temperature is raised. By adopting the forced fan 256 composed of the sirocco fan in this manner, the air volume can be increased as compared with the propeller fan, and the heat exchange efficiency in the heat exchange unit 154 can be improved.

  In addition, when the appearance of the hot air fan 230 is increased by adopting the forced fan 256 composed of a sirocco fan, not only the position corresponding to the baseboard 180 but also the wall 170 vertically above it is cut out. Alternatively, the hot air fan 230 may be installed first before the wall 170 is installed. In addition, when the hot air fan 230 is configured to be divided into two parts, the baseboard 180 is cut out in the same manner as the hot air fan 130 formed of a propeller fan, and first, only the divided upper part of the hot air fan 230 is cut out. It is also possible to construct the hot air fan 230 such that it is inserted from the notch and the divided lower part of the hot air fan 230 is inserted and integrated in a state where the wall 170 is pushed upward vertically.

(Heating method)
FIG. 7 is a flowchart showing a process flow of the heating method. First, the heat source 110 as the heat source heats the heat transfer medium (S200), and the floor heating 120 as the radiant heating device radiates the heat energy of the heated heat transfer medium (S202), and the forced convection heating device. The warm air fan 130 warms the air with the heat transfer medium that has radiated thermal energy, forcibly releases the warm air to the outside (S204), and returns the heat transfer medium to the heat source (S206).

  As described above, according to the heating system 100 and the heating method of the present embodiment, the heat transfer medium is realized by the hot air fan 130 downstream thereof while realizing a uniform and comfortable temperature distribution by the upstream and main floor heating 120. It is possible to sufficiently release the heat energy remaining in the system and improve the system efficiency.

  As mentioned above, although preferred embodiment of this invention was described referring an accompanying drawing, it cannot be overemphasized that this invention is not limited to this embodiment.
