Description

technical field [0001] The invention relates to an energy storage heat exchange device used in an energy storage heat pump system, in particular to a falling film evaporation heat exchange device for flow 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 the northern cold climate region, and there is also the problem of frosting on the outdoor heat exchanger of the heat pump cycle in regions with high outdoor relative humidity. Therefore, the air source heat pump integrated system combined with technologies in other fields has become a new development direction. Most of the integrated systems are still in the conceived stage, failing to combine the strengths and weaknesses of different types of technologies rationally. In the existing energy-storage heat pumps, most of the energy-storage heat exchangers are casing-type structures, and their...
