Abstract
An absorption heat pump apparatus is so formed that solution which has absorbed coolant vapor in absorber to increase in temperature, liquid coolant into which coolant vapor heat been condensed in a condenser, and coolant which has decreased in temperature through flash evaporation of coolant vapor in an evaporator are delivered directly to heat exchangers so as to exchange heat with the outdoor air, respectively. This arrangement makes the use of cold water and cooling water as well as equipment therefor and maintenance thereof unnecessary.
