In addition, since the hot water in the bathtub (7) is configured to be forcedly circulated by the pump P), the pump P) is operated during heating and cooling operation of the water or hot water in the bathtub (7). The same applies to the case with a pump in the example.

Next, Figure 1g8 is an example of the refrigerant circuit configuration of the second invention, in addition to the bathtub heat exchanger (2), indoor heat exchanger (4), and outdoor heat exchanger (5) in Figure 2. Hot water tank unit 1
) A hot water storage tank heat exchanger used as a condenser (
8), and the differences from the configuration shown in FIG. 8 are as follows.

The switching mechanism (X2) has an on-off valve (111) from the compressor (1) to the hot water storage tank heat exchanger (8) with an on-off valve marked U. Unlike, this pipe is connected to the - side (to) of the hot water tank heat exchanger (8).In addition, the expansion mechanism (Y,
) is composed of an expansion valve, a check valve, and an on-off valve in the same manner as above, and is connected to the other side of the hot water tank heat exchanger (8) by piping. The configuration is different from that in other respects and is the same as the configuration in FIG. 8.

FIG. 8 is as described above, in which each on-off valve of the switching mechanism (x2) is controlled to open and close, and two of the four heat exchangers and their respective expansion mechanisms are used and their expansion is performed. The mechanism is selected and various operations are performed, and the operation mode is shown in Table 2. The operating mode will be explained, and the other details are the same as those in FIG. 2, so the explanation will be omitted.

17-18- In order to heat the water in the hot water storage tank (8) for hot water supply, first, the on-off valves of the switching mechanism (Xg), C1) and the on-off valves of the expansion mechanisms (Yt) and (Ya) are activated. The hot water storage tank heat exchanger (8), which operates as a condenser with the refrigerant from the compressor + 1), expands and depressurizes with the expansion mechanism (Yl) placed on the left, and functions as an evaporator. The water in the hot water tank (8) is heated by flowing into the heat exchanger (2), and at this time the water in the bathtub (7) is heated.
When there is heat from the remaining hot water, this heat is recovered. Second, the switch +1 has a structure (Xg) cD on-off valve O.

Next, in the eighth place, the on-off valves (2) of the switching mechanism (x2), the on-off valves (4, f441) of the type 1 protection mechanism (Ya), (Y4) are opened. The refrigerant from the pressurizer (1) is expanded and depressurized by the hot water storage tank heat exchanger (8), which acts as a condenser, and the expansion valve (to) of the expansion mechanism (Y4), and is then transferred to the outdoor heat exchanger, which acts as an evaporator. Pour into the hot water tank (8).
) of water.

As described above, there are eight operation modes for heating the water in the hot water storage tank (8) for hot water supply, and any one of them can be selected depending on the n1 condition.

Next, Fig. 4 shows an embodiment of the eighth invention, which differs from the Fig. 8 example of the second invention in that a four-way valve is used for the switching mechanism (Xs), and the hot water tank heat exchanger ( ), and the expansion mechanism has the functions of fully closing, fully opening, and expanding.

That is, the switching mechanism (Xs) is a four-way valve (svs).

(8V4), on-off valves (8V1), and (8V*) are used to connect each heat exchanger to the compressor (1) so that refrigerant can reciprocate.
As expansion mechanisms, electric expansion valves fft), (Vj), (Vj),
(V4), these heat exchangers are piped in parallel.

The operation mode of the opening/closing control of each valve in this embodiment is as shown in Table 8 below.

In the jIa table above, the luck that is different from that in Figure 8 of the second invention 22
- The milling company installed and removed a return pipe for the hot water tank heat exchanger (8), which made it possible for the hot water tank heat exchanger (8) to be used as an evaporator. In addition to invention 2, the hot water in the hot water storage tank (8) is used as a heat source to rapidly heat the hot water in the bathtub (8) and exchange heat indoors with the bathtub heat exchanger (2). (4) for rapid indoor heating (
(increased heating capacity), and between the outdoor heat exchanger (5), various operations such as rapid defrost at the time of layer line to the outdoor heat exchanger (5) are possible.

that's all,#! Fig. 2 for the invention No. 1, Fig. 8 for the second invention, and Fig. 4 for the eighth invention will be explained.However, these inventions are not limited to the above embodiments, and can be modified in various ways as described below. An example of a design change is misleading.

First, in FIGS. 2 to 4, an example was described in which each heat exchanger was connected in parallel to the compressor (1), but instead of parallel connection, heat exchangers may be connected in series as appropriate. However, the same effect can be achieved.

For example, referring to FIG. 5, in the example of FIG. 4, the hot water tank heat exchanger (8) is connected in series with the other eight heat exchangers, and the hot water tank heat exchanger (8) is The pipe is provided with an on-off valve (241t), and each expansion mechanism is different at this time.In other words, the expansion mechanisms (Zl), (zg), and (Za) in Figure 5 are 7N bathtub heat exchangers. The heat exchanger (2), the indoor heat exchanger (4), and the outdoor heat exchanger (5) are installed in series between the hot water tank heat exchanger (8) and all have the same configuration. Translation~(
(to) is an expansion valve, 69 to (turn) is a check valve, and - to Kasumi is an electromagnetic opening/closing valve. - Has the function of opening or blocking. For example, the expansion mechanism (Zl)
The flow t′Lt to the bathtub heat exchanger (2) has the function of expanding and reducing pressure (expansion valve and check valve 6η), and the flow to the hot water tank heat exchanger (8).
) to expand and reduce the pressure of the flow t'L (expansion valve (branch) and check valve ■), and the function to allow or block the flow between both heat exchangers +21, 18) without reducing the pressure ( The expansion mechanisms (Za) and (Zs) have a similar structure.

In such FIG. 5, the operating mode is, for example, a bathtub (7).
When the hot water tank heat exchanger (8) is not in use, the pump of the hot water tank (8) is stopped and the on/off valves on both sides of the hot water tank heat exchanger (8) are closed. With the door open, the heat exchanger (8) simply allows the refrigerant to pass through, the bathtub heat exchanger (2) acts as a condenser, and the indoor heat exchanger (4) or the outdoor heat exchanger (5) The expansion valve is used to perform expansion and depressurization at (to) and act as an evaporator, and other operations are performed in the same manner.

In short, the unused heat exchangers are each expansion mechanism (Zi),
(Zz), (Zs) (D sonzo 1 [) on-off valve (am,
It goes without saying that various operations can be performed by appropriately opening and closing N and I51 to simply allow the refrigerant to pass through or to block the flow of the refrigerant, thereby exchanging heat between the two heat exchangers as appropriate. In addition, by expanding the concept of the example in Figure 5, in Figure 5, the hot water storage tank heat exchanger (
8) Although the heat exchangers are connected in series, it goes without saying that the same effect can be achieved even if any of the other eight heat exchangers are connected in series.

In addition, the expansion mechanism is an expansion mechanism (Y
I) to (Y4), expander'l1l (Zt
) to (z3) may be used, and if the electric expansion valve is used as shown in Fig. 4, the configuration will be simplified, and the switching mechanism 26- will also be connected to each incoming pipe as shown in Figs. 2, 8, and 5. , each opening/closing valve may be interposed in the return pipe, and if a four-way valve is used as shown in Fig. 4, the configuration will be simpler.In short, the switching mechanism can be controlled by valve control to Select the heat exchanger and expansion mechanism for two of the exchanger and its seven expansion mechanisms or the four heat exchangers and expansion mechanisms of the second invention, and connect one to the condenser and the other to the expansion mechanism. The evaporator or one may act as an evaporator and the other as a t-condenser.

Further, in the above example, the explanation is based on the indoor unit, but in order to make it a multi-room type, a plurality of indoor units may be provided in parallel.

Furthermore, the hot water tank heat exchanger (8) of the hot water tank unit IO)
As another modification example, the heat exchanger (8) is installed in the hot water storage tank (8).
) may be directly disposed to heat and cool the water in the hot water tank (8) by natural convection instead of forced circulation by the pump tP).

Various design changes other than those described above are possible, but they are included within the scope of the present invention as long as they do not depart from the purpose of the present invention.

26- The example of the present invention is as described above, but in the first invention, a bathtub unit (to), an indoor unit)), an outdoor unit (4) are attached to the compressor, By selecting two heat exchangers and their expansion mechanisms in each unit, you can heat the water in the bathtub, reheat it without adding more water when the bathtub water is low, or cool it without adding more water when the bathtub hot water is high. Beat pump operation enables indoor heating and cooling, as well as rapid indoor heating using the waste heat of the remaining hot water from the bathtub, increased heating capacity, and rapid defrost when frost forms on the outdoor heat exchanger, thereby conserving water resources. , effective multi-purpose use of electrical energy, effective use of thermal energy from waste heat, etc.
Ru.

Further, in the second invention, a hot water storage tank unit (0) is additionally installed in addition to the bathtub unit (B), indoor unit (2), and outdoor unit (4) to one compressor of the first invention. In addition to the effects of the first invention, it is possible to supply hot water to bathtubs, kitchens, washrooms, etc. while saving resources by only using hot water. In the eighth invention, 27- In addition to this, the hot water storage tank heat is used to rapidly raise the temperature of the mourning bath, rapidly heat indoors, increase heating capacity, and rapidly defrost the outdoor heat exchanger when frost forms. Electricity and thermal energy can be used effectively for multiple purposes.

As described above, the present invention provides remarkable practical effects, such as enabling multi-purpose operation that effectively utilizes energy while saving resources and energy at a low total cost.
