Parallel sharing system vortex hydraulic filling type direct cooling unit special for surface treatment industry

Abstract

The invention relates to a parallel sharing system vortex hydraulic filling type direct cooling unit special for the surface treatment industry. The parallel sharing system vortex hydraulic filling type direct cooling unit comprises a shell and tube type condenser, a hydraulic filling type corrosion prevention evaporator, a first pipeline system and a second pipeline system, wherein the first pipeline system and the second pipeline system are connected between the shell and tube type condenser and the hydraulic filling type corrosion prevention evaporator. The first pipeline system and the second pipeline system form a closed loop. The first pipeline system comprises two vortex compressor units which are connected in parallel, and each vortex compressor unit comprises multiple refrigeration compressors which are connected in parallel through pipelines, and an oil separator. The refrigeration compressors are connected with the hydraulic filling type corrosion prevention evaporator, the oil separators are connected with the shell and tube type condenser, and oil return pipelines are further connected between the oil separators and the refrigeration compressors. The second pipeline system comprises a drying filter and control valve sets which are connected in parallel and correspondingly control the different vortex compressor units. The parallel sharing system vortex hydraulic filling type direct cooling unit is reasonable and compact in structure, vortex compressors are connected in parallel to form a large-cooling capacity compressor module, and the function of small unit energy adjustment is achieved.

Description

technical field [0001] The present invention relates to a vortex flooded refrigeration equipment, in particular to a vortex flooded chiller refrigeration equipment with a plurality of parallel compressor modules sharing the system; System, the refrigeration equipment that optimizes the oil return scheme, can also be said to be the equipment that several groups of parallel scroll compressors share a refrigeration system. Background technique [0002] The existing vortex chillers are mainly dry type, and when they are used in the industry of surface treatment or corrosive brine, they all perform indirect heat exchange through an intermediate heat exchange device. Or use an anti-corrosion heat exchanger to make a dry evaporator for heat exchange, indirect heat exchange, low energy efficiency ratio, increase intermediate links, and large investment. Although the anti-corrosion dry evaporator is direct heat exchange, it is corrosive to load cold The solvent is generally very dir...
