Problems solved by technology
Electric boilers use direct heat to supply heat, converting high-grade electric energy into low-grade heat energy, which is a great waste of electric energy
Traditional heat pumps using freon and R134a tetrafluoroethane as refrigerants have the problems of high ozone depletion potential ODP or high greenhouse effect potential GWP, low water supply temperature, and low refrigeration performance coefficient COP

Description
technical field [0001] The invention relates to a domestic hot water supply system based on solar energy and a transcritical carbon dioxide heat pump, which can be widely used in domestic hot water supply for residents and commercial users, especially for large residential and commercial users. Background technique [0002] With the improvement of living standards, the demand for domestic hot water is increasing. At present, the supply of residential and commercial domestic hot water mainly depends on gas boilers, electric boilers and other industrial boilers. Gas-fired boilers are constrained by the lack of natural gas in our country and the constraints of high gas prices, and the technological development is restricted. Electric boilers use direct heat to supply heat, converting high-grade electric energy into low-grade heat energy, which is a great waste of electric energy. Traditional heat pumps using freon and R134a tetrafluoroethane as refrigerants have the problems o...
