Summary

Considering supplied domestic hot water temperature lower than the required 60°C and lower system energy efficiency of the existed system, presents the new system as solution to the above " situation. Performing the heat recovering according to cascad principle of energy use, recovers partial latent heat and total sensible heat while the condensing temperature is not risen. Presents the working modes of heat charging, discharging and standby of heat recovering system. With an actual project, presents the detailed parameters of the unit and design calculation of the heat recovering system. Operation analysis of cooling period shows that the heat recovering quantity is always more than heat demand of domestic, water f namely, the free domestic hot water can be obtained in whole cooling period.
