Description

technical field [0001] The invention relates to the field of air conditioning and refrigeration, in particular to a multi-effect regenerative heat source tower heat pump system and method. Background technique [0002] The heat source tower heat pump can effectively solve the frosting problem that air source heat pumps tend to produce in winter, and can be used in both winter and summer, with good technical and economic value. In recent years, the research and application of heat source tower heat pump systems have become more and more many. [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 antifreeze solution in the heat source tower. After absorbing moisture in the air, the concentration...

Problems solved by technology

However, since the antifreeze solution is in direct contact with the air in the heat source tower, the non-condensable gas contained in it will escape in a large amount in a vacuum environment and enter the condenser with water vapor, which will seriously affect the condensation heat transfer effect. The non-condensable gas is pretreated, and the patent application number 201410038285.8 proposes the use o
