Abstract

The invention provides a refrigeration system and method. The refrigeration system comprises a compressor, an evaporator, an oil return heat exchanger and a condenser. An air outlet of the evaporatorcommunicates with an air inlet of the compressor through a first air return pipeline. An inlet of the oil return heat exchanger communicates with a liquid outlet of the evaporator through a first oilreturn pipeline, and an outlet of the oil return heat exchanger communicates with an oil inlet of the compressor through a second oil return pipeline. An air outlet of the condenser sequentially communicates with an inlet of the oil return heat exchanger, an inlet of a return pipeline and an inlet of the evaporator through a second air return pipeline, and an inlet of the condenser communicates with an exhaust port of the compressor through an exhaust pipeline. According to the refrigeration system, oil and refrigerant mixed liquid output by the evaporator is subjected to heat exchange throughthe oil return heat exchanger and then is input into the oil inlet of the compressor, so that the exhaust superheat degree of the compressor can be stabilized.

Description

technical field [0001] The present application relates to the technical field of refrigeration, in particular to a refrigeration system and method. Background technique [0002] When the compressor in the refrigeration system is running, it usually needs oil to lubricate its interior, but the oil inside the compressor is inevitably discharged with the refrigerant gas when it is exhausted, and stays in the evaporator, affecting the evaporator and compression. normal operation of the machine. Based on this, it is necessary to return the oil in the evaporator to the compressor. [0003] However, in the related art, the method of returning oil to the compressor through the air pump can easily reduce the superheat degree of the exhaust gas of the compressor. Contents of the invention [0004] The present application provides a refrigeration system and method capable of stabilizing the exhaust superheat of a compressor. [0005] According to a first aspect of an embodiment of...
