Method of stopping an absorption refrigerator

摘要

After a running stop command is released, a pump P2 for transferring a solution from the absorber 2 to a regenerator 3 is kept running. The transfer of the solution permits separation of the solution from a refrigerant during non-operation of the refrigerator. The solution saved in the regenerator 3 remains at as a high concentration of the absorbent as that before the end of the operation while the refrigerant is saved in an evaporator 1. This enables the refrigerator to restart its normal operation corresponding to an operation start command.
