基于高低温双冷水机组的恒温恒湿洁净车间空调系统节能性分析南昌大学工程建设学院、宏伟建设股份有限公司冯显桓*摘要通过介绍广东深圳某恒温恒湿洁净车间空调系统的设计案例，依据相关的制冷、除湿、电负荷设计指标及温湿度等环境参数，选取适当的负荷系数，通过TRNSYS仿真模拟平台搭建单台低温机组和高低温双冷水组合机组两种系统，并分别对其逐时冷、热、电负荷曲线及各月供冷量及用电量进行对比分析。高低温组双冷水组合系统比单台低温机组系统耗电量节能10.23%，冷机平均COP提高了24.86%，系统COP提高了11.4%，节能效果明显。对于温湿度精度要求较高的工业厂房，低温机组除湿加高温机组降温双冷水机组的空调系统，在节约能源、室内空气品质控制方面都有比较明显的优势，值得采用和推广。关键词温恒湿；洁净车间；双冷水机组；空调系统；节能EnergySavingAnalysisofConstantTemperatureandHumidityAirConditioningSysteminCleanWorkshopBasedonHighandLowTemperatureDoubleChillersFengXianhuanAbstractThispaperintroducesadesigncaseofairconditioningsysteminaconstanttemperatureandhumiditycleanworkshopinShenzhen,Guangdongprovince.Onthebasisofrelatedrefrigeration,dehumidification,electricityloaddesignindexesandparameterssuchastemperatureandhumidityenvironment,selectingtheappropriateloadfactor,throughtheTRNSYSsimulationplatformstructures,asingleunitatlowtemperatureandhighandlowtemperaturecoldwaterunittwokindsofsystems,andthehourlycold,heat,electricityloadcurveandmonthscoolingandpowerconsumptionwereanalyzed.Comparedwithasinglecryogenicunit,thepowerconsumptionofthecombinedsystemofdoublecoldwaterinhighandlowtemperaturegroupis10.23%,theaverageCOPofchillersis24.86%,andtheCOPofsystemis11.4%.Theenergysavingeffectisobvious.Forindustrialplantsrequiringhighprecisionoftemperatureandhumidity,theairconditioningsystemofdehumidificationofdoublewaterchillerslowtemperatureunitandcoolingofhightemperatureunithasobviousadvantagesinenergysavingandindoorairqualitycontrol,whichisworthyofadoptionandpromotion.KeywordsConstanttemperatureandhumidity;Cleanworkshop;Doublewaterchillers;Airconditioningsystem;Energysaving0引言恒温恒湿洁净空调系统是一种工艺性空调，主要用...
