Description

technical field [0001] The invention relates to the field of heat exchangers, in particular to an integrated water-cooled air-cooled heat pump module unit and a multi-source system. Background technique [0002] The existing central air-conditioning air-cooled cold (hot) water (heat pump) units and water-cooled chillers have a market share of over 90%. [0003] 1. The air-cooled heat pump uses the outdoor ambient air as the cold and heat source: the advantages are cooling in summer and heating and heating in winter, one machine for dual purposes; small size, light weight, easy to transport, construction, and maintenance, and roof installation does not occupy indoor space; The parallel connection of machines is a backup system with strong stability; the disadvantage is that the condensing temperature is high during cooling, the cooling efficiency is low, and the energy consumption is more than 30% higher than that of water cooling (including evaporative cooling); the evaporat...
