Description

technical field [0001] The invention relates to a device that organically combines solar energy with an air source heat pump, realizes efficient utilization of solar energy, improves the performance of the air source heat pump, and can provide cooling and heating for buildings. It belongs to the technical field of solar energy utilization, refrigeration and air conditioning system design and manufacture. Background technique [0002] With the development of the economy and the improvement of people's living standards, the winter heating demand for buildings in the middle and lower reaches of the Yangtze River is increasing. If the northern heating mode is applied, the already prominent energy problem in our country will be more severe, so it is necessary to find a breakthrough in heating methods. In this area, solar energy resources are relatively abundant. If solar energy can be efficiently applied to the heating of buildings in this area, it will be of great significance ...
