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 solution regeneration device for a heat source tower heat pump capable of realizing dual-purpose use in winter and summer, realizing high-efficiency solution regeneration in winter and high-efficiency absorption refrigeration in summer. [0003] Background technique [0004] The heat source tower heat pump is a new type of cold and heat source system for buildings that can be used in both winter and summer. During cooling in summer, the heat source tower is used as a conventional cooling tower, so that the chiller has a higher COP. When heating in winter, the solution is used to exchange heat and mass with the air in the heat source tower, and absorb heat from the air as the low-level heat source of the heat source tower heat pump unit. Compared with the air source heat pump, the heat source tower heat pump not only has...
