AUXILIARY HEAT EXCHANGE DEVICE FOR ABSORPTION REFRIGERATION AND HEAT PUMP SYSTEM

摘要

PURPOSE: An auxiliary heat exchange device for absorption refrigeration and heat pump system is provided to prevent deterioration of heat transfer performance of the absorber and evaporator, while achieving improved operating reliability. CONSTITUTION: An auxiliary heat exchange device comprises an auxiliary heat exchanger(40) arranged at a pipe connecting an absorber(12) and a liquid heat exchanger(18). The auxiliary heat exchanger reduces superheat of a strong solution(28) and allows the strong solution to flow into the top of the absorber. The auxiliary heat exchanger uses a cooling medium for reducing superheat of the strong solution through the heat exchange with the strong solution, and the cooling medium is a coolant or a cool water. The coolant or cool water flows through a pipe(42) which is branched off from the coolant inlet/outlet.
