In the absorption type refrigerant circuit, a refrigerant such as ammonia and an absorbent such as water are enclosed, and the concentrated ammonia water solution in the regenerator 1 is heated by the combustion heat of gas or kerosene and the gas-liquid separator 2 Is separated into ammonia gas refrigerant and dilute solution, and the gas refrigerant flows into the refrigerant flow path 7, radiates heat in the condenser 3 and accumulates in the first liquid storage tank 12a, and then is decompressed and expanded by the expansion valve 4 and the evaporator 5 Absorbs the heat of vaporization and becomes a gas refrigerant again and is placed in the absorber 6, where it is absorbed by the dilute solution flowing through the dilute solution flow path 9 and flowing into the absorber 6, and becomes a concentrated solution,
After coming out of the absorber 6 and accumulated in the second liquid storage tank 12b, it is returned to the regenerator 1 by the solution pump 10.
When used as an air conditioner, the condenser 3 and the absorber 6 are cooled by the outside air, and the evaporator 5 is provided indoors for cooling. On the other hand, when used as a heater, the evaporator 5 is provided outside the room to absorb heat from the outside air, and the heat generated in the condenser 3 and the absorber 6 is released into the room for heating. Also when used as a water heater, the heat absorbed from the outside air by the evaporator 5 and generated by the condenser 3 and the absorber 6 is used for heating the hot water as in the case of the heater. In the operation of the above absorption heat pump system, when heat is drawn from low temperature outside air,
Since the expansion valve 4 operates in a throttled state, the refrigerant accumulates on the upstream side of the expansion valve 4, but the excess refrigerant in the refrigerant passage 7 accumulates in the first liquid storage tank 12a, and thus the condenser. The refrigerant does not accumulate in the condenser 3, and the condenser 3 can be operated without degrading its performance. Further, under an operating condition such as an overload condition during the cooling operation when the outside air temperature is low and the indoor temperature is high, the concentrated solution flows into the concentrated solution flow passage 11, but the concentrated solution flow is generated. Since the excess concentrated solution inside the passage 11 accumulates in the second liquid storage tank 12b, the absorber 6
A large amount of concentrated solution accumulates in the inside of the reactor, and it is possible to operate with a stable capacity without degrading the performance of the absorber.
Further, even when changing the operating state such as changing the load, the change in the refrigerant amount in the refrigerant passage 7 is absorbed by the change in the amount accumulated inside the first liquid storage tank 12a, and the concentrated solution passage 11 Change of concentrated solution in
It is absorbed as a change in the amount of the concentrated solution stored inside the liquid storage tank 12b. Further, since the change in the amount of the dilute solution in the dilute solution flow path 9 is absorbed as the change in the amount of the dilute solution accumulated inside the gas-liquid separator 2, the influence on the performance of each heat exchanger is small and the operating conditions are small. Even when the
Stable operation can be realized. In addition, fine solid matter such as dust or oxidation products mixed in the absorption type refrigerant circuit,
In the refrigerant channel 7, the first filter 13a provided in the channel connecting the outlet of the condenser 3 and the expansion valve 4 captures it, and in the concentrated solution channel 11, the outlet 6c of the absorber 6 is provided. Concentrated solution flow path 11 that connects to the solution pump 10
Since it is captured by the second filter 13b provided in
The expansion valve 4 and the solution pump 10 can realize stable operation without catching foreign matter and breaking down.

The solid matter is captured by the filter 13 provided inside. Further, iron oxide or the like generated when the refrigerant circuit is manufactured by welding or the like is firmly captured by the magnetized filter 13, and when the iron-based material filter 13 such as stainless steel is used, By providing the magnetic field generating means 14 such as a magnet on the outer wall of the liquid storage tank 12 outside the filter 13, the filter 13 is magnetized and iron oxide and the like are firmly captured. Further, by magnetizing and using the pipe forming the refrigerant circuit, iron oxide or the like can be firmly captured on the inner surface of the pipe.

The amount of solids taken out of the liquid storage tank 12 is extremely reduced because the state is settled and accumulated between the outlet pipe 15 standing in the lower portion and the liquid storage tank 12. On the other hand, the non-condensed gas existing in the refrigerant circuit is retained between the inlet pipe 16 extending downward inside the liquid reservoir tank 12 and the liquid reservoir tank 12, and the non-condensable gas flowing into the heat exchanger is not retained. The amount of condensed gas can be suppressed.
