一拖二热泵型空调器(KFR-20G×2)one-drivers-two heat pump air-conditioner(KFR-20GW X2)ABSTRACTThis article simply introduced the heat pump one-drivers-two room air-conditionerin design several questions:New green refrigerant use the calculation of thethermodynamic energy circulation,evaporator and condenser computation,air-conditionerappendix choice,as well as heat pump room air-conditioner development and forecast.The air conditioning is as the name suggests carries on the adjustment to the airparameter,in order to cause the environment to suit our request.With development of ourcountry national economy and the improvement of the people's lives level,people's livingconditions condition request also in gradually enhancement.Therefore the air conditioningholds the very important position in the daily life.Also causes the air conditioningtechnology in the unceasing enhancement,achieves the people to the environment request.The heat pump room air-conditioner both can make cold and heat,can satisfy the requestsof the winter and summer,so it gets a fast development.The air-conditioner is facing theminiaturization,the energy conservation,the intellectualization,is artistic,the healthdirection develops.In recent years,along with the housing condition change,some users stemming fromsaved spatial the consideration,started to purchase "one-drivers-two air-conditioners,the promotion pulls as soon as tows two air-conditioners the development and theimprovement.KEY WORDS The heat pump,One-drivers-two air-conditioner,New green refrigerant,Energy conservation,Environmental protection
