Description of the Related Art Conventionally, in order to increase the efficiency (COP: coefficient of performance) of a refrigerator, it was necessary to increase the heat recovery rate in the heat exchanger, but at this time, the pressure loss in the heat exchanger was large. It tends to be. For example, in the case of the conventional machine of FIG. 8, when the pressure loss of the low temperature heat exchanger becomes large, the solution cannot be completely returned to the absorber. Therefore, a J line for directly returning from the low temperature regenerator to the absorber is provided as shown by a broken line. Aside from that, it is often returned to the absorber, but the efficiency is significantly reduced. Therefore,
As shown in FIG. 9, a solution spray pump is provided to back up the pressure, but in this case, all of the circulating solution is circulated by the solution spray pump, and the individual circulating amount cannot be adjusted. It was also an economic problem.

ションを起こすのを防止する。In the absorption refrigerator, when the amount of the refrigerant liquid in the evaporator E is insufficient (the amount of the refrigerant decreases when the solution concentration in the cycle decreases), or when the amount is expected to be insufficient, the rotation speed of the solution spray pump P 4 is changed. The flow rate to the spraying device 9 is lowered. A part of the concentrated solution from the low temperature regenerator GL bypasses the heat transfer section of the absorber A, enters the diluted solution side, and increases the diluted solution concentration. This increase in concentration increases the amount of refrigerant in the evaporator and prevents the refrigerant pump from cavitation due to lack of refrigerant.

A bypass pipe 21 having 2 is provided. In FIG. 7, during heating operation, the cooling / heating switching valves V 1 and V 2 are opened, and the steam of the high temperature regenerator is guided to the A / E (absorber / evaporator) can body, and hot water passing through the inside of the evaporator tube is supplied. To heat. Here, the refrigerant vapor is condensed and becomes drain (refrigerant liquid), but the refrigerant liquid is returned to the dilute solution circulation system through the valve 2.

Therefore, the solution spray pump P 4 may be stopped. Therefore, it is possible to stop the solution spray pump and save pump power. Further, as shown in FIG. 2, the solution pump P 2 for the low temperature regenerator is used.
In the case of having the low head pump, the low head pump and the solution spray pump can be stopped to save the pump power.
