RESEARCH OF HEAT PUMP SYSTEM WITH FREEZING LATENT HEAT COLLECTION ON ENERGY-SAVING AND ENVIRONMENTAL PROTECTION
In this paper, the performance of energy-saving and environment protection is deduced and compared quantificationally of the heat pump system with freezing latent heat collection (HPSFLHC) with other systems on the basis of the annual PER and other evaluating indicators to unit volume surface water. The results show that this kind of heat pump system has much higher annual primary energy ratio (PER), only after groundwater heat pump system. And the surface water contains large amount of ice, when the city is more close to the south, the annual PER is higher. The results that obtained by calculation of environmental protection show that this kind of heat pump system has obvious benefits than other systems. When thegroundwater is not enough and the surface water has large amount, the system is more significant.
