Abstract

A solar jet-variable compression hybrid refrigeration system comprises a solar jet refrigeration system, a solar jet-variable compression cascade refrigeration system, a solar jet-variable compression coupling refrigeration system and a variable compression refrigeration system which are integrated; when solar radiation is intense, the solar jet refrigeration system operates; when solar radiationis higher than the medium level, the solar jet-variable compression cascade refrigeration system operates; when solar radiation is weak, the solar jet-variable compression coupling refrigeration system operates to sufficiently utilize part of the solar energy not utilized by the prior art, and when solar energy is extremely low or solar radiation does not exist, the variable compression refrigeration system in the system operates. The system can efficiently utilize solar energy at different levels according to the intensity of solar radiation, and sufficiently and effectively utilizes the solar energy resource.

Description

technical field [0001] The invention relates to a refrigeration device, in particular to an injection and compression composite refrigeration device driven by solar energy and electric energy, and belongs to the technical field of refrigeration. Background technique [0002] The spray refrigeration system has the characteristics of simple structure, convenient installation, stable operation, and low maintenance cost. The spray refrigeration system driven by solar energy has the characteristics of energy saving and environmental protection, and has broad application prospects in the field of air conditioning and refrigeration. [0003] When the solar jet cooling system is used for independent cooling, the jet cooling system can operate normally only when the solar energy is sufficient and there is enough heat to make the temperature of the generator higher than a certain temperature. Since solar energy changes with seasons, day and night, and climate changes, it has the chara...
