Embodiment Construction

[0011] The outlet of the solar heat collector 1 is connected with the steam generator 2 , and the hot water after heat exchange flows back to the solar heat collector through the water pump 3 . The refrigerant steam of the steam generator 2 is connected to the working steam inlet of the ejector 4 through the outlet, the evaporator 5 is connected to the refrigerant water pipe 9, the outlet of the evaporator 5 is connected to the injection steam inlet of the ejector 4, and the outlet of the ejector 4 Connect to condenser 6. The outlet of the condenser 6 is connected to the working medium pump 8 and the throttle valve 7 respectively. The outlet of the working medium pump 8 enters the generator 2, and the liquid throttled by the throttle valve 7 enters the evaporator 5. In addition, a backup gas heat source 10 is also installed in the generator 2, controlled by a temperature controller 11, for use when the solar radiation is insufficient.

Abstract

The invention organically combines an application of solar energy, gas and ejector refrigeration, and provides a novel solar energy ejecting refrigeration system. A steam generator, a pump, an inlet of a solar energy collector are orderly connected with an outlet of the solar energy collector through pipes to form a heating water circulating device; an outlet of the steam generator is connected with a working steam inlet of an ejector through a pipe, an evaporator is connected with a refrigerant pipe, an outlet of the evaporator is connected with an ejector steam inlet of the ejector through a pipe, and an outlet of the ejector is connected with the evaporator. The steam generator is also connected with a gas heater controlled by a temperature controller, heating water circulating device is at least provided with one set, if a plurality of heating water circulating devices are provided, the heating water circulating devices and the evaporator can either be connected in serial or connected in parallel. The invention has a wide adaptability, can save enormous energy, thereby reaching a refrigeration effect of sustainable high efficiency.

Description

technical field [0001] The invention relates to a novel solar gas jet refrigeration system, which belongs to the technical fields of air-conditioning refrigeration and heat utilization of solar energy. Background technique [0002] The traditional refrigeration method is mainly Freon vapor compression refrigeration driven by electric energy. However, due to the destruction of the ozone layer by refrigerants, the greenhouse effect, and the impact of power shortages, refrigeration systems driven by heat sources (such as absorption refrigeration, ejector refrigeration, etc.) have increasingly attracted people's attention. These heat source-driven refrigeration systems can use waste heat, solar energy, and gas as energy sources, thereby greatly reducing power consumption. However, the structure of the absorption system is complex, the volume is relatively large, and as the operating time increases, the performance of the system’s working medium decreases. At the same time, the ...
