DETAILED DESCRIPTION OF THE INVENTION The present invention provides integrated management of heat supply systems in houses.
Residential Savings to Get Energy Savings'', N/L
/ 4': 2 un k: Ill "J' 6゜In the conventional 41 house A3, the heat supply system is J
The heat source device is not configured to be operated as such, but a heat source device is individually provided at each heat supply destination f0, and each is operated individually as necessary. .

For example, bathtubs are reheated using gas, and hot water equipment is heated using gas, or electric heating using late-night electricity. In addition, recently some bathrooms have been equipped with dryers so that the bathrooms can function as drying rooms, but even in these cases, the dryers are operated by electricity, so that each heat supply destination is individually controlled. They are trying to manage supply. However, with such conventional equipment, it is not possible to manage the whole in an integrated manner, and in addition to being troublesome in terms of management, there is also a drawback that there is a large loss in thermal efficiency. I can't handle problems like that.
In the case of gas-fired heating, there is a risk of poisoning, explosion, or fire due to gas leakage from equipment or piping, as well as the risk of poisoning due to incomplete combustion of the equipment. If you use it, if the hot water heated by late-night electricity is used up, hot water will not come out until the next morning, or the stored hot water temperature is as high as 85 degrees Celsius, so there is a risk of burns. JI because there is no reheater
I! There are problems such as not being able to reheat the boiler or boil it twice.

The present invention has been made in view of the above circumstances, and focuses on the fact that there is a difference in the heat demand time of each heat supply destination, and uses a heat pump system as the heat supply system, Compressors, heat absorbers, etc. are used as dual-purpose equipment, and are configured so that they can selectively supply heat to each heat supply destination. The aim is to provide 11 Shoji Takugawa energy equipment that can be managed efficiently and efficiently, and as a result improve thermal efficiency.

The present invention provides that, in a bathroom equipped with a dryer and a bathtub with reheating, and a hot water supply system equipped with a hot water tank, the times during the day when drying, reheating, and hot water are supplied are from daytime to evening to night. By paying attention to the fact that they are different from each other, such as during the night and during the night, the heat pump is also used, and the dryer operation, heat for the reheater, and heat for the hot water tank/11 can be performed individually and selectively. Its features include a heat pump Ao that supplies heat to the dryer, reheater, and hot water tank;
Heat pump Δ1 that also serves as the compressor of pump Ao
The heat radiating coil side of the heat pump Ao consists of heat exchange coils connected in parallel to each other corresponding to the reheating device and the hot water tank, and the heat exchange coil is connected to the heat pump A. The heat radiating coil and the heat absorbing coil installed in the heat pump A1 circuit are connected to each circuit through an open 111 valve, respectively, and are placed on the air blowing side and the air intake side of the dryer. and the heat radiation in the heat pump A1 circuit =
The point is that a separate heat radiation mechanism is provided between the J coil compressors to lower the temperature of the refrigerant in the circuit.

In that case, the heat from the heat exchange coil for heat for the reheater may be supplied to the reheater via a heat exchange circuit that circulates hot water using a circulation pump.

Further, it is also possible to use the heat absorption coil arranged in the circuit of the heat pump A, as in the heat radiation 411 structure of the above-mentioned separate heat pump A.

In the following, the present invention will be explained in detail based on illustrative embodiments.

FIG. 1 shows the configuration of an embodiment of the present invention. In FIG. It is equipped with a dryer 4. In addition, 5 is a hot water tank, and from this hot water tank 5, hot water pipes (not shown) for supplying water to various places are led out as usual. On the other hand, a heat absorber 7 with a fan 6 is provided outdoors.

・Thus, a heat pump 80 for supplying heat is constructed by connecting the hot water tank 5, the reheater 2, and the heat absorber 7, and the dryer 4 is operated using the compressor C of the heat pump Ao. Monthly l and -1-pump A1 are configured. These heat pumps A o eΔ1 share the compressor C, and the lil Ill valves S1 to S are connected to the headers 9 and 10 before and after the compressor C, respectively
The refrigerant is selectively circulated to heat pumps 80 and Δ1 (including both cases) by appropriately combining and operating the above-mentioned valves SV1 to SV7, which are connected in parallel via V7 and J3. It is now possible to do so.

As is well known, the heat pump Ao is a combrella (JC1
It consists of a heat radiation coil\expansion valve V, and a heat absorption coil 8 in the heat absorber 7, and here, as the heat radiation coil side, two heat exchange coils 2a and 5a corresponding to the reheating device 2J and the hot water tank 5 are used. are provided in each device. Note that the heat exchange coil 2a of the reheater 2111 is included in the device, and is indicated in parentheses (=
The l symbol indicates a small number, and illustration thereof is omitted.

These two heat exchange coils 2 a s J a are connected to the heat dissipation coil header; 9.11 and are connected in parallel to Im In valves S V 1 , S V 2 , S respectively.

By operating the reheater, it is possible to selectively circulate the refrigerant (here, a high-temperature refrigerant is used) to the reheater 2a and the hot water detection coil 5a (including both cases). It has become. Moreover, the heat pump A1 has a heat radiation coil (condensing coil) 4a, a heat absorption coil (evaporation coil) 4b1, and an expansion valve 12 inserted in front of the heat absorption coil 41+, with the compressuna C at the center. is arranged on the air outlet side Fa of the air circulation passageway [of the dryer 4], and the heat absorber 1il 4b is arranged on the air intake side Fb.

In addition, in the circuit of the pump A1, there is a separate radiator installed between the heat radiating coil 4a and the compressor C in the same circuit.
Drawing 13 is arranged in stages. In this embodiment, this separate heat radiation (413) is constituted by a coil with a fan.

OJ and each opening/opening valve SVI to SV7 are &II not shown.
It is controlled by the headband III, and everything is centrally managed.

Next, we will explain the functions of the equipment used in the book by referring to Figures 2-4. A case will be described in which each form is actually t-1.

[Hot water supply (see Figure 2)] Heating for the dry water supply ff5 is mainly carried out at night, especially late at night, when electricity rates are low.

The control device opens and opens the valve SV2. SV3,5V5SV7
With the valve SV1. SV4,
When SV6 is heard, compressor C is activated and the cold tofu is compressed into high-pressure, high-temperature gas. The compressed refrigerant gas, which has become high in temperature, flows to the left in the figure, and flows through the open valve SV1 (13J1) in the direction of the arrow through the passage 4' indicated by the solid line. That is, it flows through the header 9 to the heat exchange coil 5a in the hot water supply tank 5, where it radiates heat and heats the hot water supply tank 5.
It condenses itself. After that, the refrigerant flows to header 1 as shown by the arrow.
1, is expanded by an expansion valve V, and flows to an endothermic coil 8 (also referred to as an evaporator coil), where it absorbs heat from the surrounding air heat source and evaporates itself into gas. - Returns to the compressor via the inner header 10. This is circulated and carried out in a 3!IVt manner, and the hot water is supplied to the 4f
The inside of f5 is heated to 65°C. When the setting temperature of the lagoon reaches tQ, the ti control device automatically detects it and turns on the compressor C.
If the temperature of the hot water tank 5 becomes low again,
j 1m Compressor C operates to heat Ij 1. E
Make sure to keep the amount of S you need for the day in your back at night. Note that heating may be performed even during the daytime when the temperature drops. In that case, the amount of heat necessary for hot water supply is small, so even if 41 is used for other additional heating and drying, the capacity will not decrease.

[Re-burning, see Figure 31] Re-burning of bathtubs is mainly done from evening until TT. Is this a normal bath? Fi is activated by activating the compressor C using the switch in the compressor. l1ll linked to that switch! l valve SV1. SV3. SV4. SV7 is 1! l U 13t

The hot water flows in the direction of the arrow through the on-off valve SV2, where the heat is radiated and the hot water in the bathtub 3 is directly heated by the heat exchange filter 28.

At the same time, the refrigerant follows the route of the header 10 and returns to the -C compressor C in the same way as in the case of hot water supply, and this is circulated continuously to perform reheating. In addition, when the required hot stone temperature (45°C) is reached, turn off the switch.

[Drying (see Figure 4)] Drying is carried out during the day when bathroom 1 is not in use. By the control device (between 11 valves SV
3 and SV7 are opened, the other valves are opened, and the compressor C is operated, and the refrigerant in the heat pump Al is compressed and becomes high temperature and pressure, and as shown by the solid line, it is separately placed via the header 9. A certain amount of heat is radiated by the flow to the heat radiating mechanism 13 of
It flows along the direction of the arrow in the heat exchange coil 4a in the dryer 14 and warms the circulating air flow r. The refrigerant is then expanded by the expansion valve 12 and flows to the heat absorbing coil 4b in the dryer 414, where it absorbs heat and lowers the temperature of the air stream.

At this time, as the temperature decreases, the moisture in the -C air flow condenses, exerting a dehumidifying effect. Due to the heating effect and dehumidification effect due to the heat radiation, the temperature inside the bathroom 1 reaches 30°C.
Maintaining a dry condition of 40% Rl-1 promotes rapid drying of the laundry.

As described above, it is possible to selectively supply heat by making good use of the differences in the heat demand time zones of each heat supply destination.
Since dual-purpose equipment can be provided, equipment costs can be reduced, and heat supply can be managed in an integrated manner. As a result, we have realized a heat supply system that is easy to manage, efficient, and energy saving.

In J3, hereafter, in Ninowo 2mei, we have described the case where drying, reheating, and hot water supply are performed individually, but when they are combined with each other! (Of course, it is also possible to execute it in multiple ways.

In the case of C, it is sufficient to operate the on-off valves SVI to SV7 and to appropriately give input to the control shield.

In the above embodiment, the cold tofu of the heat pump 80 is introduced into the lj indirect stoker 2 and heated, but the part indicated by X in Fig. 1 is used as a heat exchanger. 7
It can also be configured as shown in the figure. The heat exchange coil in the heat pump A corresponding to the reheater 2 is shown as 28 in the figure, and the heat dissipated by the coil 2a is circulated to the heat exchange circuit 14 having a 1 m pump 17 to circulate the dry water. By doing so, it is supplied to the reheater 2.
Therefore, coils 15 and 1G (16 is in the reheater 2 and not shown) are provided at both ends. If you do this, the coil 2a will break 10C and the high temperature n
Since high pressure refrigerant does not enter the reheating device 2, safety is improved. In this case, since the temperature of the lagoon in the bathtub 3 is about 45° C., it is optimal to use water as the heat medium in the heat exchange circuit 14, but it is of course possible to use other heat medium.

Next, another embodiment of the present invention will be described with reference to FIG. The feature of this embodiment is that the heat pump A is used as the above-mentioned separate heat dissipation mechanism. The point is that the heat absorber 7 is used in the circuit, and the other points are the actual tM shown in FIG.
Same as IN. Therefore, parts that are the same as those shown in FIG. In this embodiment, the header 10 has a 1FiIII valve S.
A return pipe from the heat absorption coil 4b is connected via V7,
As a result, the heat sink 7A+ has a J, 4M configuration in which the heat absorber 7 is just interposed in the system.

This equipment requires J3 (°, if operating dryer 4,
The refrigerant from the compressor C flows through the header 9 to the coil 8 in the heat absorber 7 as shown by the arrow, and after some heat is dissipated here, it flows to the heat radiation coil 4a, and returns to the compressor C via the heat absorption coil 4b. flowing on the road. This yields the incense fruit of the above-mentioned example.

In addition, as shown in FIG.
t] can be done. That is, an 11-shaped duct 1-30 is installed on the outer wall of the building, and a heat absorption coil 31 and a fan (Fig.
At the same time, dampers 32a to 32d are installed in each branch flow path in the H-shaped duct 30, and dampers 32a, 32b and dampers 320.32 (I are interlocked with each other). Then, these dampers 32a~
In opening and closing 32d, the air flow fi that circulates indoor air and the air flow fo that circulates outdoor air can be selected by switching.

By adjusting this temperature, the temperature difference between the heat absorption coil side and the heat radiation coil side can be appropriately adjusted to increase, thereby further increasing the operating efficiency of the P1 pump.

As explained above, according to the present invention, heat can be selectively supplied by utilizing the difference in heat demand time zones of each heat supply destination, and these heat supply systems can be connected to a heat pump system. As a result, the heat supply can be managed in an integrated manner, and the thermal efficiency of the entire equipment can be improved, resulting in an energy-saving effect. Furthermore, since the entire system is comprised of a heat pump, there is no risk of gas leakage, and it is extremely safe. Roughly speaking, individually, hot water is supplied to the P1 pump, so in addition to supplying the necessary and sufficient amount of water with safe humidity and little heat loss, it is also possible to add water to the bathtub. Since it is equipped with a stove, it is possible to boil the bath twice, and there is also a dryer in the bathroom, so you can wash and dry clothes while the bath is not in use. It can demonstrate extremely effective II+ on the Ichiri River surface.

In addition, another 1. Vl
