Description
technical field [0001] The invention relates to heating and cooling equipment, in particular to a refrigeration heat pump device coupled with solar injection and compression. Background technique [0002] As a renewable energy source, solar energy has the advantages of cleanness, environmental protection, free use, and no need for transportation. However, solar energy can only be used when there is solar radiation. Air is available everywhere and has the advantages of safety, convenience, and cleanliness, but the heating efficiency of using air is far lower than that of using solar energy for heating. [0003] The injection system has the advantages of simple structure, no consumption of mechanical energy in the compression process, and the use of renewable energy, so it has become a way to help solve the problems of environmental pollution and energy consumption. However, the relatively low coefficient of performance of the injection system limits its application in the fi...
