Abstract

The invention discloses a heat source tower heat pump device achieving solution low-pressure boiling regeneration through heat of subcooling. The heat source tower heat pump device comprises a refrigerant loop, a solution loop, a vacuum maintaining loop, an air loop, a regeneration solution heating loop and a cold and hot water loop. According to the heat source tower heat pump device, the characteristic of solution boiling point depression in vacuum is fully utilized for solution regeneration, on the premise that heating operation of a heat pump system is not influenced, heat of subcooling of system liquid refrigerants is used as solution regeneration heat, the solution regeneration problem of the heat source tower heat pump system is completely solved, reliability of heating operation of the heat source tower heat pump system in winter is improved, and system comprehensive high efficiency is achieved.

Description

[0001] technical field [0002] The invention belongs to the field of design and manufacture of refrigeration and air-conditioning systems, and relates to a heat source tower heat pump device which utilizes the supercooled heat of a refrigerant to realize low-pressure boiling regeneration of a solution. [0003] Background technique [0004] In recent years, the issue of heating in the south has received more and more attention, and has become a hot topic related to social and people's livelihood. With the improvement of people's living standards, in hot-summer and cold-winter regions in my country, the requirements for heating time and comfort in winter are getting higher and higher, and heating energy consumption in winter is increasing rapidly. [0005] In the existing conventional air-conditioning cold and heat source scheme of the building, the efficiency of the air source heat pump is low in summer cooling, and there is frosting problem in winter heating; when the chi...
