Description

  The present invention relates to an air conditioning system that performs air conditioning in a plurality of rooms.

  With the spread of airtight houses and air conditioners, it is now common to install air conditioner indoor units for each room in a building. In addition, air obtained by intensive air conditioning at one location in order to reduce the use space in each room and the complexity of construction work by installing indoor units of air conditioners in each room Centralized air conditioning systems that supply conditioned air to each room have also been developed.

  For example, Patent Document 1 discloses a duct that communicates with each room of a building, an air circulation path that is connected to a base end portion of the duct, and air that is sucked into the building and sucked into the air circulation path. Integrated centralized air conditioning unit equipped with a blower module that sends air to each room through the air conditioning module that ventilates the air in the air circulation path with the outside air and adjusts it to the required temperature with a heat source machine to harmonize it with a predetermined state Is described. In this integrated centralized air conditioning unit, air conditioned in a predetermined state by the air conditioning module is sent to each room by a blower module and a duct. Therefore, between the air conditioner (indoor unit) installed in each room and one outdoor unit As compared with the case of constructing a system that circulates high-pressure refrigerant or the like and performs air conditioning for each room, the construction is simplified. In addition, if the integrated central air conditioning unit is installed outdoors, it is not necessary to install an air conditioner (indoor unit) in any room, so that the use space in each room is prevented from being reduced.

The blower fan drive unit 35 and the on-timer 37 are electrically connected to the power switch S, and the first damper drive unit 36 is electrically connected to the on-timer 37. The first damper 27 closes the second suction wind tunnel portion 22B when it is “on”, and opens the second suction wind tunnel portion 22B when it is “off”.

The piping unit 10, the air conditioner 20, and the blower 60A (see FIGS. 1 and 2) described above are provided, and the air conditioner 20, the control unit 40A of the blower 60A, the motors 28 and 32 (see FIG. 3), In the air conditioning system 100A (see FIG. 1) connected in a predetermined state, when the user turns on (closes) the power switch S (see FIG. 3), each of the air conditioner 20 and the blower 60A is activated. The supply of conditioned air to the rooms R _{1 to} R ₂ (see FIG. 1) of the building 150 is started. The first damper 27 is activated later than the air conditioner 20 and the blower fan 31 (see FIG. 3).

  FIG. 4 is a time chart schematically showing the operation timing of each unit in the air conditioning system shown in FIG. As shown in the figure, when the user turns on (closes) the power switch S at time T1, the air conditioner 20 and the blower fan 31 are activated (turned on) in synchronization therewith. The first damper 27 is activated (turned on) at time T2 when the on-timer 37 issues an on-signal to the first damper driving unit 36 (see FIG. 3).

The air conditioner 20 activated at time T1 creates conditioned air by setting the temperature and humidity of the room air in the room R ₂ to a predetermined state. Also, when the blowing fan 31 at time T2 is started, and the conditioned air suction port 21a in the room R _2, the first and second suction air channel portion 22A, 22B and, via a suction port 45a and the blower 60A The air is sucked into the blower main body 45, and blows out from here through the blowout portion 47 to the blowout wind tunnel portion 24 (see FIG. 2). Then, the conditioned air blown out to the blow-out wind tunnel portion 24 is sent into the pipe portion 10 (see FIG. 1) from the blow-out port 21b (see FIG. 2) and is sent to the rooms R _{1 to} R ₄ (see FIG. 1). It is discharged (supplied). Since both the first suction wind tunnel portion 22A and the second suction wind tunnel portion 22A function as a flow path for the conditioned air, the conditioned air produced by the air conditioner 20 can be rapidly supplied to the rooms R _{1 to} R _4. Is possible.

However, until the time T2, the first damper 27 is turned “off” and the second suction wind tunnel portion 22B is opened, so that the conditioned air cleaned by the air cleaning portion 26 (see FIG. 2) and The conditioned air that has not been cleaned is sucked into the blower main body 45 and supplied to the rooms R _{1 to} R ₄ . At time T2, the first damper 27 is turned on and the second suction wind tunnel portion 22B is closed. As a result, only the first suction wind tunnel portion 22A of the first and second wind tunnel portions 22A and 22B functions as a flow path of conditioned air. Only air will be delivered.

According to the air conditioning system 100A (see FIG. 1) operating in this way, the time difference Ta between the time T1 and the time T2 (FIG. 4) according to the performance of the air conditioner 20, the size of the rooms R _{1 to} R ₄ , and the like. For example, immediately after returning home, the temperature environment and humidity environment of each room R _{1 to} R ₄ are rapidly adjusted, and then the conditioned air that has been cleaned is gently put into the individual rooms R _{1 to} R ₄ . it is possible to maintain the temperature environment and humidity environment of supplying the rooms R ₁ to R ₄ in.

Then, in the air conditioning system 100A, so installing the air conditioner 20 and the blower 60A in separate locations of the room R _2, even if it is not possible to secure a space at one location together in the room R _2, also building 150 Even if the site S (see FIG. 1) is small, it is easy to construct the air conditioning system 100A by installing the air conditioner 20 and the blower 60A. It is easy to secure the installation space.

In addition, since the air purifier 26 (see FIG. 2) is provided in the blower 60A, by appropriately cleaning the air purifier 26, it is possible to suppress the growth of various germs in the pipe 10 that is difficult to maintain. Is possible. Furthermore, in the case where conditioned air is rapidly supplied to the individual rooms R _{1 to} R ₄ , the second suction wind tunnel portion 22B in which the air cleaning portion 26 is not provided, in other words, the second suction with low pressure loss. Since conditioned air can be sucked also from the wind tunnel portion 22B, even in this case, the driving force of the blower fan 31 (see FIG. 3) does not need to be increased so much, and the energy consumption can be easily suppressed.

Embodiment 2. FIG.
The air conditioning system of the present invention can be configured to control the supply and shutoff of conditioned air for each floor or room in a building. In configuring the air conditioning system in this way, for example, a second damper that opens and closes a flow path in the piping unit is provided at a predetermined location of the piping unit, and a temperature detector is provided for each floor or room in the building. It is done.

FIG. 5 is a schematic diagram illustrating an example of an air conditioning system capable of controlling the supply and blocking of conditioned air for each floor in a building. The air conditioning system 100B shown in the figure is installed in a two-story building 150 and can supply conditioned air to the first floor rooms R ₁ and R ₂ and the second floor rooms R ₃ and R _4. At the same time, the system can control the supply and shut-off of conditioned air for each floor of the building 150.

In this air conditioning system 100B, one second damper 63a is provided in each of the first-floor side branch pipe parts 5a and 5b in the pipe part 10, and a second damper 63b is provided in each of the second-floor side branch pipe parts 7a and 7b. One by one. The first floor room R ₁ is provided with a first temperature detector 65 a that detects the temperature of the first floor in the building 150, and the second floor room R ₃ has the second floor temperature in the building 150. A second temperature detector 65b for detection is provided. And the said air conditioning system 100B is provided with the air blower 60B instead of the air blower 60A shown in FIG. Except for these points, the air conditioning system 100B has the same configuration as the air conditioning system 100A shown in FIG. Among the constituent elements shown in FIG. 5, those common to the constituent elements shown in FIG. 1 are denoted by the same reference numerals as those used in FIG. 1 and description thereof is omitted.

  Each of the above-mentioned second dampers 63a is driven by a motor (not shown) whose operation is controlled by the blower 60B, and switches the first floor side branch pipe portions 5a, 5b to an open state or a closed state in synchronization with each other. Similarly, each of the second dampers 63b is driven by a motor (not shown) whose operation is controlled by the blower 60B, and the second-level side branch pipe portions 7a and 7b are switched to an open state or a closed state in synchronization with each other. . The first temperature detector 65 a detects the first floor temperature in the building 150, and the second temperature detector 65 b detects the second floor temperature in the building 150. The detection results of the first temperature detector 65a and the second temperature detector 65b are sent to a control unit (not shown) of the blower 60B. Of course, the air conditioning system 100B may be configured such that the control unit of the blower 60B reads the detection results of the first temperature detector 65a and the second temperature detector 65b.

  FIG. 6 is a connection diagram schematically showing a connection state in the air conditioning system shown in FIG. As shown in the figure, the air conditioner 20 (abbreviated as “air conditioner” in FIG. 6) in the air conditioning system 100B (see FIG. 5) and the control unit 40B of the blower 60B are connected to the power switch S. When the power switch S is turned on (closed), the operation is started. When the power switch S is turned off (closed), the operation is stopped.

  The control unit 40B controls the operation of the blower fan drive unit 35 that controls the operation of the motor 32 for the blower fan 31 and the motor 28 for the first damper 27 (see FIG. 5), similarly to the control unit 40A shown in FIG. A first damper driving unit 36, and an on-timer 37 that is interposed between the first damper driving unit 36 and the power switch S to define the operation timing of the first damper driving unit 36. The control unit 40B also includes a first-floor second damper driving unit 38a that controls the operation of the motors 64a for the second dampers 63a (see FIG. 5), and motors 64b for the second dampers 63b (see FIG. 5). The second floor second damper drive unit 38b for controlling the operation of the first temperature detector 65a, the first comparator 39a for comparing the detected value of the first temperature detector 65a with the reference temperature range, and the detected value of the second temperature detector 65b for the reference temperature range The second comparator 39b for comparing with the second comparator 39b.

The first comparator 39a generates an operation signal when the detected value of the first temperature detector 65a is out of the reference temperature range, sends the operation signal to the second floor second damper drive unit 38a, and receives the operation signal. The first-floor second damper drive unit 38a sends a drive signal to the motor 64a for each second damper 63a to switch the open / close state of each second damper 63a. For example, when the temperature range in which the user does not feel uncomfortable without performing air conditioning is set as the reference temperature range, each time the detected value of the first temperature detector 65a deviates from the reference temperature range, The second damper 63a is switched from the closed state to the open state, and the conditioned air can be supplied to the rooms R ₁ and R ₂ .

Similarly, the second comparator 39b creates an operation signal when the detection value of the second temperature detector 65b is out of the reference temperature range, and sends the operation signal to the second-floor second damper drive unit 38b. The second floor second damper drive unit 38b that has received the drive signal is sent to the motor 64b for each second damper 63b to switch the open / close state of each second damper 63b. Thereby, the supply of the conditioned air from the blower 60B to the rooms R ₃ and R ₄ (see FIG. 2) on the second floor is enabled.

  Therefore, in the air conditioning system 100B, the supply and shut-off of conditioned air are automatically controlled for each floor according to the temperature of each floor in the building 150. The blower 60B is configured such that each reference temperature range used in the first comparator 39a and the second comparator 39b is preset by the manufacturer of the air conditioning system 100B and stored in a storage unit (not shown). It is also possible to configure the setting so that the user makes settings from a remote controller, for example.

  The air conditioning system 100B having the above-described configuration has the same technical effect as the air conditioning system 100A (see FIG. 1) described in the first embodiment. In addition, since the supply and shut-off of conditioned air are automatically controlled for each floor in the building 150, the waste of supplying the conditioned air to the floor at a temperature at which the conditioned air need not be supplied is prevented. As a result, the energy consumption can be easily reduced even when compared with the air conditioning system 100A described in the first embodiment.

  Further, as indicated by a one-dot chain line in FIG. 6, each of the first comparator 39a and the second comparator 39b is electrically connected to the first damper driving unit 36, and the first comparator 39a and the second comparator 39 are connected. When at least one of the devices 39b generates the above-described operation signal, the operation signal is also sent to the first damper drive unit 36, and the air conditioning system 100B is configured so that the first damper 27 is changed from the closed state to the open state. You can also. If comprised in this way, the waste of energy that the air blower 60B (refer FIG. 5) will drive with a high output will be prevented until it is not necessary to supply the conditioned air which the air conditioner 20 produced rapidly to each room. be able to. If this configuration is applied to the air conditioning system 100A described in the first embodiment, the same technical effect can be obtained.

The indoor side exhaust piping part 77 a communicates with the rooms R _{1 to} R ₄ in the building 150, and the outdoor side exhaust piping part 77 b communicates outside the building 150. By driving the exhaust fan 71a, the indoor air in each of the rooms R _{1 to} R ₄ is sucked into the heat exchange ventilator 75 through the indoor exhaust pipe portion 77a, and passes through a predetermined flow path in the heat exchanger 73. After flowing, it is discharged out of the building 150 through the outdoor exhaust pipe 77b. In FIG. 7, the flow direction of the room air in the heat exchange ventilation unit 80 is indicated by a dashed arrow.

  In addition, the outdoor air supply piping section 78a communicates with the outside of the building 150, and the indoor air supply piping section 78b communicates with the first suction wind tunnel section 22A (see FIG. 2) of the blower 60C.

The blower 60D is shown in FIG. 2 except that the blower 60D has a connection port for the air supply pipe 88 on the outside of the air purifier 26 (see FIG. 2) in the first suction wind tunnel 22A. It has the same configuration as 60A.

  The air conditioning system 100D including the circulation humidification unit 90 that operates as described above has the same technical effect as the air conditioning system 100A described in the first embodiment. Further, in synchronization with the activation of the air conditioner 20 and the blower 60D, or after the humidifier 85 is activated after a predetermined time has elapsed since the activation, the humidifier 85 is used in addition to the air conditioner 20. Since air conditioning (humidification) is also performed, there is a technical effect that the convenience for the user is higher than that of the air conditioning system 100A described in the first embodiment.

  The air conditioning system of the present invention has been described with reference to the embodiment. However, as described above, the present invention is not limited to the above embodiment. The air-conditioning system of the present invention includes a piping section that serves as a flow path for conditioned air, an air conditioner that is installed in one room in a building to produce conditioned air, and an air conditioner in the room in which the air conditioner is installed. It is basically sufficient if it is provided with a blower that is installed at a location separated from the pipe and connected to the pipe section and sucks conditioned air in the room and sends it out to the pipe section, and other configurations can be changed as appropriate.

  For example, the number of suction wind tunnels provided in the air blower constituting the air conditioning system may be one. In the case where only one suction wind tunnel is provided in the blower, it is possible to appropriately select whether or not to provide an air purifier on the front side of the suction wind tunnel. Further, whether or not to provide a damper for opening and closing the suction wind tunnel can be selected as appropriate. However, from the viewpoint of supplying clean conditioned air to each room in the building, it is preferable to provide the air purifier in the air blower regardless of the total number of suction wind tunnels provided in the air blower. . And, in order to provide the air conditioning system with a function capable of rapidly supplying conditioned air to each room in the building with a small amount of energy consumption, as described in the embodiment, the front side is air-cleaned. It is preferable to provide the air blower with a suction wind tunnel in which the portion is disposed and a suction wind tunnel in which the damper is disposed.

  As in the air conditioning system described in the second embodiment, when a damper is arranged in a piping section to control the supply and shut-off of conditioned air, the damper must be provided for each floor or room of the building. Instead, it can be provided only in the desired floor or only in the desired room. About the air-conditioning system of this invention, a various deformation | transformation, modification, combination, etc. are possible besides having mentioned above.

  The air conditioning system of the present invention is suitable as a home or business use air conditioning system.
