The company has developed a CO2 heat pump assist solar water heating consisting of a cross critical CO2 heat pump system, a thermal water cycle, and a solar thermal collector system that are interconnected and loop forming. The utility model combines a carbon dioxide heat pump water heater with a solar water heating, and can provide four modes for making hot water, which can meet the hot water supply needs of different climatic regions. At the same time, the utility model makes full use of the advantages of the trans-critical carbon dioxide heat pump water heater, and the hot water of 50 °C TO 90 °C can be prepared even in the severe cold area. And because the use of natural working fluid carbon dioxide and solar energy can achieve energy-saving, environmental protection effect.
