Refrigeration Principle Of Solar Air Conditioning

Apr 23, 2020

The so-called solar energy refrigeration is to use the solar collector to provide the heat medium water for the absorption chiller. The higher the temperature of the heat medium water is, the higher the performance coefficient (also known as cop) of the refrigerator is, and the higher the refrigeration efficiency of the air conditioning system is. For example, if the temperature of the heat medium water is about 60 ℃, the cop of the refrigerator is about 0-40; if the temperature of the heat medium water is about 90 ℃, the cop of the refrigerator is about 0-70; if the temperature of the heat medium water is about 120 ℃, the cop of the refrigerator can be more than 110.


It has been proved by practice that the solar air conditioning combined with heat pipe vacuum tube collector and LiBr absorption chiller has opened up a new application field for solar energy heat utilization technology.
