Abstract

The invention provides a hot water supply system and method using solar energy preferentially. The system comprises a water heating tank and a heat accumulation tank, bilateral control of water flow between the water heating tank and the heat accumulation tank is achieved through two pipelines, one pipeline is provided with a water changing circulating pump, the water heating tank is in two-way connection with a solar thermal collector, the other pipeline is provided with a solar circulating pump, and the bottom of the water heating tank is respectively connected with a cold water opening and an air source heat pump. The system and the method of the invention can enable the solar circulating pump and the air source heat pump to alternatively heat and give play to the advantages of each other, take full advantage of solar energy while giving play to the energy-saving advantage of the air source heat pump, ensure available hot water at any time while meeting hot water supply during the hot water use peak in the afternoon and in the evening. In addition, the system is easy to control and the energy saving effect is very good.

Description

technical field [0001] The invention relates to the field of hot water supply, in particular to a hot water supply system and method using solar energy preferentially. Background technique [0002] Under the trend of energy saving and environmental protection, hot water supply with the help of solar energy has become a very popular technology, and solar water heaters have gradually entered people's daily life. However, existing solar water heaters are still highly dependent on power supply, and cannot save power to a great extent. For example figure 1 An existing solar hot water supply system shown in , which includes air source heat pump 1, solar collector 2, solar circulation pump 3, heat pump circulation pump 4, water delivery pump 5, hot water supply pump 6, water inlet Solenoid valve 7, return water solenoid valve 8, exhaust valve 9, liquid level detection devices 10, 11, solar hot water storage tank 12, constant temperature water tank 13, and five temperature collect...
