Problems solved by technology

Excessive refrigerated oil in the evaporator will reduce the heat transfer efficiency of the refrigeration system. Therefore, a stacked casing type evaporator is needed to reduce the internal refrigerant cycle of the evaporator under the condition that the external heat transfer area of ​​the evaporator remains unchanged. The effective volume of the evaporator is improved by increasing the flow rate of the refrigerant to improve the heat exchange efficiency of the evaporator

Abstract

The invention discloses a laminated tube-in-tube evaporator, and relates to the technical field of vapor-compression refrigeration systems. The laminated tube-in-tube evaporator comprises an evaporator, wherein the outer part of the evaporator is an outer sleeving tube; an inner lining tube is mounted in the outer sleeving tube; the outlet end of the evaporator is sequentially connected with a compressor, a condenser and a throttling device; the outlet end of the throttling device is connected to the inlet end of the evaporator to form a cyclic refrigeration system; a refrigerant is filled inthe cyclic refrigeration system; the refrigerant flows out from the outlet end of the compressor, sequentially flows through the condenser, the throttling device and the evaporator and finally flows into the inlet end of the compressor; and the inner lining tube is arranged at the inlet end of the outer sleeving tube. By arranging the inner lining tube inside the outer sleeving tube of the evaporator, the laminated tube-in-tube evaporator is capable of reducing the internal volume without reducing the heat exchange area of the evaporator, improving the flow rate of the refrigerant in the evaporator, prolonging the effective refrigeration time, and improving the heat exchange efficiency of the refrigeration system.

Description

technical field [0001] The invention belongs to the technical field of vapor compression refrigerating systems, in particular to a stacked casing type evaporator. Background technique [0002] The vapor compression refrigeration system is a closed circuit. The compressor drives the refrigerant to circulate in the condenser, capillary, evaporator, return pipe and other components in order to transfer heat. The low-temperature refrigerant flows in the evaporator, and the refrigerant is in the state of wet steam in the evaporator. The humidity at the inlet end is high, and the flow rate is low. The refrigerant absorbs the surrounding heat through the evaporator, and its dryness gradually increases, and the flow rate gradually increases. . [0003] Refrigerators and air conditioners are vapor compression refrigeration systems. The compressors are turned on and off periodically to control the constant temperature in the box or room. At the beginning of the compressor startup, th...
