で、経済的な冷暖房・給湯ヒートポンプ装置を得ること
を目的とする。As described above, when hot water is heated by a conventional heat pump device, one of the indoor heat exchangers 3a and 3b is replaced with a heating coil 8, and this heating coil 8 is connected to the hot water storage tank 7, as shown in FIG. Since the system heats the water in the hot water tank by heating the refrigerant circuit, it is not possible to perform economical operations such as recovering waste heat from cooling to heat hot water. Further, since the heating coil 8 is provided only in the lower part of the hot water storage tank 7a, the entire inside of the hot water storage tank 7a has to be heated at once, which causes problems such as a large heat radiation loss and a long time required to boil up the entire hot water tank.

FIG. 1 is a refrigerant circuit diagram showing the configuration of an embodiment of the present invention. Reference numerals 1 to 10 are the same as in FIGS. 5 and 6, and 11
is a three-way valve that switches the flow path of high-temperature, high-pressure refrigerant discharged from the compressor 1, and its inflow port 11g and one discharge port 11b are connected. Further, the discharge port 11C of the three-way valve 11 is connected to one end of the heating coil 8, and the other end of the heating coil 8 is connected to both ends of the expansion mechanism 4 via separate electromagnetic valves 12, 13. 14 is an inverter for controlling the capacity of the compressor 1; 15 is a control device for controlling the three-way valve 11, the solenoid valves 12, 13, and the inverter 14;
Detection signals from a temperature sensor 18 that detects the lower water temperature of the hot water tank 7 and a detector 16 that detects the upper water temperature of the hot water storage tank 7 are input, and are connected to the heater 17 . Next, the operation of the embodiment of the invention configured as described above will be explained. (a) [At the time of one chamber, the high temperature and high pressure refrigerant discharged from the compressor 1 is
The inflow port lla and the discharge port 11b of the four-way valve 2 pass through the broken line HR of the four-way valve 2 to one or both of the indoor heat exchangers 771933a and 3b, where it is condensed, then depressurized by the expansion mechanism 4, and then transferred to the outdoor It evaporates in the heat exchanger 5, and the evaporated refrigerant gas returns to the compressor 1 through the four-way valve 2. (b) During cooling, the refrigerant discharged from the compressor 1 at this time is the three-way valve 11,
Four-way valve 2 from inflow port lla and discharge port 11b
It reaches the outdoor heat exchanger 5 via the solid line B path, where it condenses by exchanging heat with the outside air, and is further depressurized by the expansion mechanism 4, and then flows into one or both of the indoor heat exchangers 3a and 3b. To 1, evaporate. This evaporated gas refrigerant returns to the compressor 1 via the four-way valve 2. (c) During cooling hot water supply In this case, the refrigerant discharged from the compressor 1 reaches the heating coil 8 from the inflow port 11a and the discharge port 11C of the three-way valve 11, where it is condensed, and as a result, the water in the hot water storage tank 7 heat up. and. The condensed liquid refrigerant passes through the electromagnetic valve 13 and reaches the expansion mechanism 4, where it is depressurized and then transferred to the indoor heat exchanger 3.
a and 3b, where it absorbs indoor heat and evaporates, and this gas refrigerant returns to the compressor 1 via the solid line of the four-way valve 2. In this way,
Hot water will be heated and cooled at the same time. (d) At the time of heating hot water, the refrigerant discharged from the compressor 1 passes through the three-way valve 11.
The water flows from the inlet port 11a and the discharge bow 1-11c to the hot water tank heating coil 8, where it condenses and heats the water in the hot water tank 7. The condensed liquid refrigerant then passes from the electromagnetic valve 12 through the expansion mechanism 4 to the outdoor heat exchanger 5, where it evaporates. The evaporated gas refrigerant returns to the compressor 1 via the four-way valve 2. In the device of this invention, temperature sensors 1 are installed at the upper and lower parts of the hot water storage tank.
B, has 18. The upper temperature sensor 16 detects the temperature of hot water in the upper part of the hot water storage tank 7 and whether or not the hot water exceeds a certain set amount, and the lower temperature sensor 18 detects the temperature of the hot water in the lower part. For example, when hot water is urgently needed and the hot water is not boiling, or during heating operation, heating is normally given priority, but for this reason, the heating coil 8 of the hot water storage tank 7 is not sufficiently heated. Naturally, the amount of heat storage decreases. Therefore, in the present invention, a case will be described in which a storage tank heating operation is performed by a heater in addition to heating by the heating coil 8 in order to ensure a certain amount of heat storage or more, with reference to the heater heating operation control flow shown in FIG. The program for the control procedure shown in FIG. 2 is stored in the internal memory of the control device 15. In FIG. 2, in step S1, the upper temperature sensor 16 detects the hot water temperature T1 at the heater 17 position, and the lower temperature sensor 18 detects the hot water temperature T2 at the lower part of the storage tank 7. Next, in step S2, the heat storage amount Q of the hot water storage tank 7 is determined from the set temperature of the upper temperature sensor 16 so as to be constant.
Here, Vl and V2 represent the amount of hot water above the heater position and the amount of hot water from the heater position to the bottom of the hot water tank 7, respectively, as shown in Fig. 3, and the respective hot water temperatures are assumed to be T t and T 2. . In step S3, it is determined whether or not the hot water temperature T1 detected by the upper temperature sensor 16 is lower than the set temperature T1'. The heater 17 is turned on and heats the hot water above the heater position with a hot water amount v1 and a hot water temperature T1, and if the temperature is higher than the set temperature T1', proceed to step S4b,
Heater 17 is turned off. As shown in FIG. 4, when hot water with a hot water volume v2 and a hot water temperature T2 is heated by the heating coil 8 installed at the bottom of the hot water storage tank 7, the hot water temperature rises to T 2 +a and the heat storage amount Q is kept constant. In this case, the set temperature of the upper temperature sensor 16 falls to T+'-a' (however, α≧0). In addition, the amount of hot water v1 above the position of the heater 17, the hot water temperature T
Since the heater 17 is turned on for hot water No. 1, the temperature of the hot water is T.
It increases to 1+β (however, β≧0). In the above embodiment, the indoor heat exchanger is 3a. Although the case where there are two units 3b has been described, this can be similarly applied to the case where there are three or more units. Further, instead of the three-way valve 11 as a switching valve, a combination of two two-way valves may be used, or the three-way valve 11 may be a solenoid valve capable of controlling flow rate and temperature.

回収が可能となる。As explained above, this invention has a tanabata in the upper part of the hot water storage tank, and the temperature is controlled by two temperature sensors installed at the upper and lower parts of the tank, so that only the upper part of the hot water tank is heated to high temperature. It has the advantage of being able to heat up, keep the amount of heat storage constant, and compensate for the temperature of hot water supplied from the faucet. In addition, a switching valve was installed to add high-temperature, high-pressure refrigerant discharged from the compressor to the heating coil, and the water in the closed container was heated and the condensed refrigerant was returned to the compressor through an indoor-outdoor heat exchanger, making cooling and heating possible. This makes it possible to recover waste heat from cooling, which can be used to heat and supply hot water at the same time.
