The invention discloses a carbon dioxide steam spraying refrigerating system, which aims at providing a refrigerating system less in initial investment, low in system operation cost, simple in structure and high in reliability. An outlet of an air cooling device is respectively connected with an inlet connecting pipe of a first sprayer and an inlet of a first expansion valve, an outlet connecting pipe of the first sprayer is connected with an inlet of the air cooling device through a first valve, an outlet of the first sprayer is connected with an inlet of an evaporator, and an outlet of the evaporator is divided into two branches. One branch of the outlet is connected with an injecting inlet connecting pipe of a first injector through a third valve, and the other branch of the outlet is connected with an inlet of a working medium pump through a second valve. An outlet of the working medium pump is connected with an inlet of the air cooling device. The refrigerating system adopts an injector to replace a refrigerating compressor, initial investment of the system is less, only the working medium pump is needed to be opened to build pressure difference between the air cooling device and the evaporator, structure is simple, and operation cost is low. Reliability of the system is not affected by a refrigerating compressor and is high, operation is convenient, and control is simple.
Description
technical field [0001] The invention relates to the technical field of refrigeration, in particular to a carbon dioxide vapor injection refrigeration system in which an ejector replaces a refrigeration compressor. Background technique [0002] The conventional carbon dioxide refrigeration cycle system contains a refrigeration compressor. The low-temperature and low-pressure gas from the evaporator enters the refrigeration compressor, and is compressed by the refrigeration compressor into a high-temperature and high-pressure gas, which is discharged to the gas cooler or condenser. The initial investment of the refrigeration compressor is relatively high, which directly causes the investment cost of the refrigeration system to increase. At the same time, the refrigeration compressor needs to consume work during operation, and the operating cost of the system is high. Moreover, the reliability and operating performance of the refrigeration compressor directly affect the reliab...
