Absorption type heat pump device

摘要

An absorption type heat pump device including a generator for generating refrigerant vapor, a condenser, an evaporator, an expansion valve, an absorber, a solution pump, a passage member for leading strong solution from the generator to the absorber, and a heat exchanger. The heat exchanger and/or the passage member is provided with a portion in which a pressure drop is made larger than a drop in equilibrium pressure resulting from a temperature drop so as to perform flow control of the strong solution.
