Study of CO2 Heat Pump for Coupled Hot Water Supply and Room Heating System

摘要：

The CO2 heat pump system is built for hot water supply and room heating．It is can realize high temperature heating supplying for control room and hot water supplying for living.The different parts operation Can meet different demands and achieve energy saving． For the hot water manufacture, the high temperature water Can be got through controlling water flow by the test rig．As the test result，its concluded that the efficiency and water flow IS higher than other working conditions when the environment temperature is 25℃．In the process of room heating, the floor radiation Can supply enough heating to keep the room temperature at 45℃，SO this system gail be USed in dry sauna system or other dry system．In addition，it IS tested that the rig Can supply room heating for control room and the hot water for living at the same time．
