At this time, the absorption refrigerant channel 11 is filled with a working medium such as an NH 3 aqueous solution or a LiBr aqueous solution and heated by the regenerator 1, whereby NH 3 flows through the refrigerant channel 6 as a thick vapor. A freezing effect can be obtained by condensing and liquefying and radiating heat in the condenser 2 and decompressing by the expansion valve 3 to evaporate in the evaporator 4 and absorbing as latent heat of evaporation. On the other hand, the thin aqueous solution from which NH 3 has been removed in the regenerator 1, that is, the dilute solution, flows through the dilute solution circuit 11, is decompressed by the decompression valve 7, and enters the absorber 5. At this time, the NH 3 vapor flowing from the evaporator 4 is absorbed by the dilute solution, so that the absorber 5 generates a concentrated NH 3 aqueous solution, that is, a concentrated solution, and radiates heat. The concentrated solution discharged from the absorber 5 is again sent to the regenerator 1 through the concentrated solution circuit 10 by the solution pump 9 to be regenerated.

きる。At this time, the hot water supply is 2
Water is supplied from the water supply pipe 18 to the next side and heated, and the water heater 1
However, when the load is small, the hot water heater 19 does not need to consume heat energy because the hot water supply temperature can be sufficiently obtained by the first radiator 15a. Further, when the amount of heating in the absorber 5 and the condenser 2 becomes excessive, the temperature of the heat radiation medium may rise and boil, but the first heat radiator 15a
By providing a hot water supply temperature detecting means 22 such as a thermistor at the outlet of the device, the opening degree of the valve 20 of the bypass circuit 21 is reduced when the hot water supply temperature is detected and the temperature approaches the boiling temperature.
Boiling can be prevented. On the other hand, when the load is large and the like, the required flow rate of hot water supply increases, so the flow resistance of the first radiator 15a increases, and the required flow rate may not be obtained. By increasing the opening degree, a large amount can be flowed to the bypass circuit 21 to guarantee the flow rate, and the water heater 19 can be used by heating it to a required temperature. Further, when there is no hot water supply load, the operation of the absorption cycle can be guaranteed by operating only the second radiator 15b to radiate heat to the outside air or the like.

Further, since the feed water temperature is generally lower than the outside air temperature, the temperature of the heat radiation source in the absorption cycle can be lowered and the system performance of the absorption cycle itself can be improved. Furthermore, even when used for hot water supply, it is possible to realize a high-performance composite system with multiple types of loads in a compact system without making the absorption cycle and other component parts of the absorption cycle excessive. it can. Furthermore, for hot water supply, a wide range of operations from large load to small load can be achieved by setting the bypass circuit and valve.

The obtained heat is stored in the hot water storage unit 24. Further, when the hot water supply and the absorption cycle side are operated at the same time and the first radiator 15a has a large amount of heat radiation and the required hot water supply temperature is sufficiently obtained, the valve 20a is opened according to the temperature detected by the hot water supply temperature detecting means 22. By increasing the flow rate of the bypass circuit 21 by increasing the temperature
The heat will be stored in. If hot water is needed next, valve 2
0a is opened and the valve 20b is closed.
The hot water stored in the water heater 1 is sent to the water heater 19 and the water heater 1
The heating energy of No. 9 is also reduced, the required temperature can be obtained in a short time, and a hot water supply system with excellent rising characteristics can be realized.

ことができる。Next, the first radiator 15a and the second radiator 15b
The amount of heat radiation is controlled by the valves 20a and the fans 27 provided on the respective secondary sides according to the temperatures detected by the first heat radiation temperature detecting means 25 and the second heat radiation temperature detecting means 26 provided at the respective outlets on the primary side. It can be done by For example, when the hot water supply load is small, the first heat radiation temperature detection means 25 rises, but the operating temperature of the first radiator 15a is kept constant by increasing the opening degree of the valve 20a until the temperature reaches the set temperature. In the case of the second radiator 15b as well, when the load is small, the second heat radiation temperature detecting means 2 can be maintained.
Although the detected temperature of 6 increases, the operating temperature of the second radiator 15b can be kept constant by increasing the rotation speed of the fan 27 until the temperature reaches the set temperature. Therefore,
Since the operating temperature of the heat radiating portion on the absorption cycle side can be kept constant, the high pressure is also kept constant and stable operation can be realized. Further, by adjusting the opening degree of the heat radiation passage valve 29 and adjusting the flow rate of the heat radiation circuit 17 so as to keep the temperature of the absorber temperature detecting means 28 provided at the secondary inlet of the absorber constant. The operating temperature of the heat radiating section on the absorption cycle side can be kept constant, and by controlling the rotational speed of the heat radiating circulation pump 16 to adjust the flow rate of the heat radiating circuit 17, the heat radiating on the absorption cycle side can be performed similarly to the above. The operating temperature of the part can be kept constant.

The operating temperature of the evaporator 4 can be maintained at a constant value by adjusting the opening degree of 1 and adjusting the flow rate of the heat absorption circuit 14, and the rotation speed of the heat absorption circulation pump 13 can be changed according to the detected temperature. And the flow rate of the heat absorption circuit 14 are also adjusted to maintain the operating temperature of the evaporator 4 at a constant value. Further, in the case of operating the aqueous ammonia solution at a high temperature in the working medium, in order to increase the concentration of the ammonia refrigerant flowing through the refrigerant passage 6 from the outlet of the regenerator 1, the temperature between the regenerator 1 and the condenser 2 is increased. The rectifier 32 is required. At this time, since the operating temperature of the rectifier 32 is higher than that of the condenser 2, the water supplied from the water supply pipe 18 is warmed to a high temperature by the rectifier 32 after being warmed to an intermediate temperature by the first radiator 15a. Next, since the water heater 19 is heated to a required temperature and used, the heating energy of the water heater 19 is further reduced.

Thus, a hot water supply / heating system that can be used for heating and can be operated by a heat pump by radiating heat to indoor air can be realized. In addition, when operating the 2nd radiator 15b at high temperature, or in the system in which the load of hot water supply is always large, the 1st radiator 15a and the 2nd radiator 15b.
