Abstract

A refrigerant distributor of evaporator in compression-refrigeration falling film type is prepared for connecting refrigerant inlet to refrigerant longitudinal tensile distribution tube being connected with refrigerant horizontal tensile capillary tube, setting a row of small holes at bottom of each said capillary tube, setting porous material layer under said distribution tube and said capillary tube, arranging steel plate mesh under porous material layer and porous plate under steel plate mesh then arranging a flow guide silk screen under porous plate.

Description

technical field [0001] The invention relates to a refrigerant distributor in the technical field of refrigeration, in particular to a refrigerant distributor for a compression refrigeration falling film evaporator. Background technique [0002] In the range of large and medium-sized refrigeration capacity, the main refrigeration units used are screw type and centrifugal type. The evaporator is the main heat exchange equipment in the refrigeration system. Whether the evaporator is properly selected is directly related to the cooling effect of the entire refrigeration device and directly related to the energy consumption of the operation. In centrifugal and screw chillers, there are three main forms of evaporators: flooded evaporators, dry evaporators and falling film evaporators. Among them, the horizontal tube falling film evaporator has been used in refrigeration, chemical industry, petroleum refining, seawater desalination and other industries. In the refrigeration and a...
