长沙某医院洁净空调系统设计

Design of clean air conditioning systemin a hospital in ChangshaAbstractThis design is a clean air-conditioning system for a hospital building in ChangshaHunan Province.It is based on the principle of providing economical and applicable schemefor hospital and clean operating environment for medical treatment.The hospital has twofloors,a height of 3.2 m,an area of 4322 m',the proposed clean area uses a decentralized fullair system,the unclean area uses a fan coil plus an independent fresh air system,each enddevice is equipped with a regulating system and power switch,this scheme can independentlyadjust and control the temperature and humidity of each room,occupy less area,can alsoachieve centralized cooling.Design Content:Find the building plan,collect the local meteorological data;input thebuilding information and room information with Tianzheng HVAC,calculate the cooling loadand wet load of each room;Next is to determine the system plan suitable for this project andplan the air conditioning system partition,after the calculation,select the terminal device andair conditioning unit according to the calculation result,then select the chilled water system,arrange the air conditioning waterway and carry on the water pipe hydraulic calculation,update the pipe diameter,control the imbalance rate of parallel pipe,then select the air floworganization,arrange the air duct and carry on the air duct hydraulic calculation,update theair duct diameter,finally select the machine room equipment and carry on the air conditioningunit,then select the chilled water system,arrange the air conditioning waterway and carry onthe water hydraulic calculation,then select the air flow organization,arrange the air duct andcarry on the air duct hydraulic calculation,update the air duct diameter,finally select themachine room equipment and carry on the air conditioning unit.Layout.The design through careful and rigorous calculation,check and design,to meet the airconditioning design standards.Keywords:Clean air conditioning;all air system;fan coil.
