Problems solved by technology

[0004] Although the above-mentioned water heaters have the characteristics of energy saving compared with traditional electric water heaters or fuel oil and gas water heaters, there are still defects in varying degrees: although the heat pump water heater has a high performance coefficient, it still consumes more electric energy during operation, and the low-temperature work Under these conditions, the coefficient of performance is greatly reduced, which is not conducive to energy conservation and environmental protection; solar water heaters cannot produce hot water in rainy days, and their operation is severely restricted by regions and weather, so the scope of promotion and use is limited
Moreover, the current heat pump water heater is difficult to realize instant use

Description

technical field [0001] The invention belongs to the field of household appliances, and in particular relates to a phase-change heat storage type solar energy instant heat heat pump system. Background technique [0002] With the continuous development of society and the depletion of non-renewable energy, people fully realize the importance of developing and utilizing renewable energy, and their awareness of energy conservation has been further strengthened, and they are more inclined to purchase energy-saving products that use renewable energy. [0003] Heat pump water heaters and solar water heaters are advanced energy-saving products today. Heat pump water heater absorbs low-grade heat energy in air, water or soil, and through compressor work, it becomes high-grade heat energy that can be better utilized to produce hot water to meet people's daily needs; solar water heaters absorb solar radiation energy to To produce hot water for life. [0004] Although the above-mention...
