The invention belongs to the technical field of heating and cooling, and provides a solar air source heat pump, including: a solar heat collector, an air source heat pump, a third liquid / liquid heat exchanger, and a user-side device; the solar heat collector is connected to a The air source heat pump and the user-side device; the air source heat pump includes: a plurality of air-cooled heat exchangers and heat pump units; the plurality of air-cooled heat exchangers are connected to the heat pump unit through a first liquid pump, The heat pump unit is connected to the user-side device; the user-side device is connected to the plurality of air-cooled heat exchangers through the third liquid / liquid heat exchanger. Through the use of multiple air-cooled heat exchangers, the air-cooled heat exchangers that do not need to be defrosted are used to absorb the heat energy of the air, and the hot water is produced by the heat pump unit, which is passed into the air-cooled heat exchangers to be defrosted for defrosting, ensuring The reliability of defrosting is improved, and the effect of defrosting is improved. At the same time, the continuity of heating is guaranteed during defrosting.
Description
technical field [0001] The invention relates to the technical field of heating and cooling, in particular to a solar air source heat pump. Background technique [0002] With the shortage of energy and the enhancement of environmental protection awareness, the development and utilization of renewable energy has attracted much attention, and solar energy is a safe and clean renewable energy, which is widely used in the production of hot water. However, the use of solar energy is greatly affected by weather changes and is unstable. Traditional solar heating devices cannot use solar radiation at night, or in the case of weak solar radiation, due to the solar heat collection in solar water heating devices The heater leaks heat, and the temperature of hot water produced by the solar heating device cannot meet the user's needs. [0003] The air source heat pump uses the working principle of the heat pump to produce high-temperature hot water by using the low-grade heat energy in t...
