Abstract

The invention discloses a condensed water discharge performance test bench for a micro-channel evaporator, which includes a compressor, and the refrigerant outlet at the right end of the compressor communicates with the refrigerant inlet at the left end of the condenser through an oil separator; The refrigerant outlet at the right end of the condenser communicates with the refrigerant inlet at the right end of a thermal expansion valve through a mass flow meter and a solenoid valve in turn; the refrigerant outlet at the left end of the thermal expansion valve communicates with a microchannel evaporation The refrigerant inlet at the lower right end of the compressor is connected; the refrigerant outlet at the upper right end of the micro-channel evaporator is connected with the refrigerant inlet at the left end of the compressor through a second shut-off valve; the micro-channel evaporator is located in a hollow, sealed air duct) inside. The invention can effectively detect the condensed water discharge performance of the micro-channel evaporator, reliably grasp the heat exchange performance of the micro-channel evaporator, and has great practical significance in production.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a condensed water discharge performance test bench for a microchannel evaporator. Background technique [0002] At present, microchannel heat exchangers have been widely used as condensers, and have the advantages of low overall cost, high efficiency, energy saving, and space saving. The problem is that when the surface temperature of the fins it has is lower than the inlet air dew point temperature of the micro-channel evaporator, condensed water will be generated on the fins. At the same time, since the fins of the micro-channel heat exchanger are mostly louver fins, Its structure is easily blocked by water droplets, resulting in poor discharge capacity of condensed water, and the surface condensation of the micro-channel evaporator will seriously affect the heat transfer effect of the micro-channel evaporator, which will easily cause the heat transfer performance of the ...
