Abstract

The absorption type heat pump restrains heat conduction efficiency reduction of a heated medium. The absorption type heat pump is provided with an absorber (10) utilizes an absorption liquid (Sa) to absorb the heat generated in refrigerating medium steaming (Ve) so as to heat a heated medium (W) circulating in a heat conduction pipe (12), allowing the heated medium (W) to evaporate in the heat conduction pipe (12); the heat conduction pipe (12) is provided with a preheated pipe (12p) for heating up a heated medium liquid (Wq), and an evaporating pipe (12e) for evaporating the heated medium liquid (Wq) after heating up by the preheated pipe (12p). The absorber (10) is configured to have one end of each evaporation pipe (12e) connected to an evaporation pipe distribution portion (14es), and the other end connected to an evaporation pipe collection portion (14ec). The evaporation pipe distribution portion (14es) and the evaporation pipe collection portion (14ec) are respectively formed; the heated medium (W) flowing in each evaporation pipe (12e) does not flow together from the evaporation pipe distribution portion (14es) to the evaporation pipe collection portion (14ec).

Description

technical field [0001] The present invention relates to an absorption heat pump, and more particularly, to an absorption heat pump that suppresses a decrease in heat transfer efficiency to a heated medium. Background technique [0002] There is known an absorption heat pump that guides refrigerant vapor generated from an evaporator to an absorber, and in the absorber, heats a liquid of a heated medium by using the heat of absorption generated when the absorption solution absorbs the refrigerant vapor to generate a heated Steam heating medium. In order to prevent the flow of the heated medium from being hindered by volume increase when the liquid of the heated medium changes into vapor, the flow of the heated medium becomes unstable, and the absorber is configured as follows. In this absorber, a plurality of pipes through which a medium to be heated flows are arranged horizontally. Water cavities are respectively arranged at both ends of the plurality of tubes. The water c...
