Description

technical field [0001] The invention relates to the field of air conditioning and refrigeration, in particular to a multi-stage flash regeneration heat source tower heat pump system and a multi-stage regeneration method. Background technique [0002] When the air source heat pump is used in winter, it is easy to produce frosting problems; and the heat source tower heat pump can effectively solve the problem of frosting that is easy to occur in winter. It is suitable for use in winter and summer, and has a good Therefore, in recent years, there have been more and more researches and applications on heat source tower heat pump systems. [0003] Currently, a major problem in heat source tower heat pumps is the regeneration of antifreeze solutions. When the heat source tower is used in winter, the antifreeze solution will absorb water vapor in the air, and the latent heat transferred by the condensation of water vapor is usually less than 30% of the heat absorbed by the antifre...
