Description

Technical field [0001] The invention relates to an energy storage heat exchange device for an energy storage heat pump system, in particular to a falling film evaporation heat exchange device for mobile phase change energy storage. Background technique [0002] At present, air source heat pumps have been widely used in various regions, but there is a problem of low heating efficiency in cold climate areas in the north, and frosting of the heat pump cycle outdoor heat exchanger in areas with high outdoor relative humidity. As a result, air source heat pump integrated systems combined with technologies in other fields have become a new development direction. Most integrated systems are still in the design stage, failing to make rational combinations of different types of technologies. In the existing energy storage heat pumps, most of the energy storage heat exchangers are of the tube-in-tube structure. The disadvantages are: 1) The tube-in-tube accumulator consumes a lot of metal ...
