A NOVEL HEAT EXCHANGE 2ND STATION BASED ON EJECTOR HEAT PUMP
A novel heat exchange 2ed station based on ejector-heat-pump is presented and studied in this current paper to improve the amount of heat that the secondary circuit can obtain at the condition of the primary circuits parameters (inlet temperature and rate of flow) unchangeable.The ejector is driven by the original hot water of the primary circuit.Theoretical and experimental study is carried out for the new system in this current paper.The experimental study showed that the new system can improve the heat supply by 21% to the heat user than the traditional system.The new system can increase heating area by about 20% in the original wa-ter supply temperature; or increase the supply water temperature by 4℃ and improve the Human Comfort Index by about 24% under the original heating area.
