Abstract

The invention discloses a novel compression auxiliary jetting refrigerating system with a supercooler. The novel compression auxiliary jetting refrigerating system comprises a compressor, a condenser, an evaporator, a generator and an ejector. An outlet of the evaporator is connected with an inlet of the compressor. An outlet of the compressor is connected with a driving fluid inlet of the injector. An outlet of the ejector is connected with an inlet of the condenser. An outlet of one way of the condenser is connected with an inlet of the generator through a pump. An outlet of the ejector is connected with an inlet of the condenser. An outlet of one way of the condenser is connected with an inlet of the generator through a pump. An outlet of the generator is connected with a working fluid inlet of the ejector. An outlet of another way of the condenser is connected with a first inlet of the supercooler through a first throttling device. A first outlet of the supercooler is connected with a driving fluid inlet of the injector. An outlet of the third way of the condenser is connected with a second inlet of the supercooler. A second outlet of the supercooler is connected with an inlet of the evaporator through a second throttling device. The novel compression auxiliary jetting refrigerating system is high in efficiency and low in energy consumption.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a compression-assisted injection refrigeration system. Background technique [0002] The continuous deepening of industrialization has continuously improved human living standards, but it has also brought a series of serious side effects, such as global warming, energy depletion, and environmental pollution. These problems have seriously affected human security. Among them, refrigeration technology is an important part of modern industry and an important field of energy consumption. It has become a consensus to develop energy-saving refrigeration technology. [0003] The ejector refrigeration system is an energy-saving refrigeration method, because it can use low-grade thermal drives such as industrial waste heat, waste heat, solar heat, and geothermal heat to generate cooling capacity. In addition, the injection system has simple flow, less moving parts, convenient opera...
