METHOD FOR OPERATING ABSORPTION HEAT PUMP DEVICE

摘要

PROBLEM TO BE SOLVED: To prevent the purity of refrigerant vapor vaporized in a rectifier and entering a condenser from being lowered even when a load changes. SOLUTION: In an absorption heat pump device, a condenser 3 is provided above a rectifier 2 and alcohol refrigerant whose evaporation temperature is low is used. The rotating speed of a cooling water circulating pump 32 for supplying cooling water E to the condenser 3 is controlled so that a temperature sensor 50 for detecting the atmosphere temperature of an upper part inside the rectifier 2 detects a prescribed temperature.
