Novel solar gas-injection refrigerating system

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 ...

Problems solved by technology

In the prior art, a single energy source is generally used as a heat source to drive and heat the refrigerant, such as a solar collector, which can save a lot of energy and achieve a good cooling effect when the solar radiation is sufficient, but when the solar radiation is insufficient, the refrigeration system won't work
