Abstract
A refrigeration system, comprising an evaporator, a condenser, a throttling device, a compressor, an economizer and an ejector, these devices together form a closed-loop refrigerant circulation loop, the ejector being connected to the economizer, and the ejector being provided on an exhaust side of the compressor. The structure enables the refrigeration system to realize the dual-stage boost, does not affect the stability of the compressor due to the instability of the airflow of the ejector, and does not affect the oil property of the compressor, thereby ensuring the operation safety of the compressor.
