2.Structural Features and Working Principle
2.1MainFunctions
SIC-R2waterchillerismainlymade up offourcomponents.Theyare
compressor, condenser, thermostateexpansion valveand evaporator. The
machine usessinglestagevaporcompressionrefrigeration systemand takes
the advantageofthe mechanismoftransformation between gasand liquidfor
absorbingand releasing heatbyusingof refrigerant toachievethe
effectivenessofrefrigeration.
2.1.1WorkingPrinciple
A. Water-cooled Series
Picture2-1:WorkingPrinciple
When theSIC-Wwater-cooledwaterchillerstartingup,compressorstarts
working.Refrigerantiscompressed intohigh temperatureand high pressure
gasintheprocess fromBtoC,andthenbecooledwhen passingthroughthe
condenserand changedintoliquid.Heatistaken awaybythe coolingwater.In
the process fromCtoDtoE and F,the liquidrefrigerant isdried andfiltered by
drierfilter.Afterthat, itwill pass throughsolenoidvalve,refrigerantindicatorand
thenreachexpansionvalve.Intheprocess fromFtoG,thehighpressureliquid
refrigerantwill be throttled anddepressurized byheatexpansionvalveand
temperaturewill godown. IntheprocessfromG toA, chilledwaterabsorbsthe
heatofprocesswaterintheevaporatorand returnsback tocompressor.This
heatexchangeprocessrepeatsuntil processwateriscooled downtorequired
temperature.
