DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention has
When the expansion valve is operated in a throttled state such as when low temperature is required, the refrigerant accumulates on the upstream side of the expansion valve, but the first refrigerant is formed in the refrigerant flow path connecting the condenser and the expansion valve. Since the liquid storage tank is provided, the excess refrigerant that has accumulated in the refrigerant flow path does not accumulate in the condenser but accumulates in the first liquid storage tank, so the performance of the condenser does not deteriorate. Also, under operating conditions such as overload conditions during cooling operation when the outside air temperature is low and the indoor temperature is high, the concentrated solution accumulates in the concentrated solution flow path between the absorber and the solution pump, Second in the concentrated solution flow path that connects the absorber and the solution pump
Since the liquid reservoir tank is provided, the excess concentrated solution that accumulates in the concentrated solution flow path will not accumulate in the absorber, but will accumulate in the second liquid reservoir tank, and the operation will be performed without degrading the performance of the absorber. be able to. Further, even when the operating state such as changing the load is rapidly changed, the amount of the working medium present in the refrigerant channel, the concentrated solution channel and the dilute solution channel also changes rapidly, but in the refrigerant channel The amount of the refrigerant is increased / decreased inside the first liquid storage tank, the amount of the concentrated solution is increased / decreased inside the second liquid storage tank in the concentrated solution flow passage, and the amount of the diluted solution is changed in the dilute solution flow passage. By increasing / decreasing the inside of the, stable operation can be performed without deteriorating the performance of the condenser and the absorber. In particular, when a heat exchanger having a small inner volume such as a plate type is used as the heat exchanger of the condenser or the absorber, the above-mentioned effects are particularly remarkable.

Further, fine solid impurities such as dust or oxidation products mixed in the absorption type refrigerant circuit are provided in the refrigerant passage connecting the outlet of the condenser and the expansion valve. Captured by the first filter,
In the concentrated solution flow path, since it is captured by the second filter provided in the concentrated solution flow path that connects the outlet of the absorber and the solution pump, the expansion valve and the solution pump are clogged with solid matter, and the operation is disabled. Without a doubt, it can be operated stably. In addition, the first filter is provided in the first liquid storage tank where the flow velocity of the refrigerant is the lowest, and the second filter is provided in the second liquid storage tank where the flow velocity of the concentrated solution is the lowest. , Solids are reliably captured by the first and second filters. Further, by using a magnetic material having magnetism for the first filter and the second filter, solid impurities such as iron oxides produced when welding the iron-based material or the like forming the refrigerant flow path,
The impurities are reliably captured by the first filter and the second filter, and the impurities once captured by the respective filters are firmly held by the filters due to the magnetic force, so that they will not be circulated again in the refrigerant channel.

Further, since the magnetic field generating means is provided in the absorption type refrigerant circuit in which the first filter and the second filter made of the iron-based material are installed, the first filter and the second filter are magnetized and the The oxidation product can be attached to the filter. In addition, since the magnetized piping is used for the piping that constitutes the absorption refrigerant circuit, the iron oxide in the working medium flowing inside the piping can be attached to the inner surface of the piping. It is possible to prevent the water from accumulating in the tank and the operation of the expansion valve and the solution pump from becoming impossible. Further, since the outlets are provided at the bottoms of the insides of the first liquid storage tank and the second liquid storage tank, and the pipes of the outlets are started up inside, the dust or the oxidation products existing inside the absorption type refrigerant circuit are prevented. Fine solid impurities can be precipitated and retained inside. Further, since the pipe inlet is provided in the upper part of the inside of the first liquid storage tank and the second liquid storage tank and the inlet pipe is extended downward, the non-condensable gas existing inside the absorption type refrigerant circuit is It can be stored in the upper part inside the first liquid storage tank and the second liquid storage tank above the pipe end. Further, since the cooling heat exchanger is provided in the concentrated solution flow path that connects the second liquid storage tank and the solution pump, the concentrated solution can be supercooled by the cooling heat exchanger,
Since a concentrated solution containing no gas is supplied to the solution pump, the carrier flow rate can be stably maintained at a predetermined flow rate.

Further, since the cooling heat exchanger is provided inside the second liquid storage tank, the concentrated solution can be surely cooled inside the second liquid storage tank with a simple structure. Also,
Since the outlet of the evaporator, the heat exchanger for cooling, and the gas side inlet of the absorber are connected in order, the low-temperature refrigerant gas and concentrated solution that have left the evaporator can exchange heat, Refrigerant gas exiting the heat exchanger becomes high-temperature superheated gas and enters the absorber, which improves absorption performance and
Since the concentrated solution is supplied to the solution pump in a supercooled state, the solution pump can be operated stably with a small flow rate fluctuation.

In the operation of the above absorption heat pump system, when heat is drawn from low temperature outside air,

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

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

Further, in FIG. 3, the solid matter mixed in the working medium flowing from the inlet pipe 16 of the liquid reservoir tank 12 is
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.
