Experimental Study on the Operating Characteristics of Solar Heat Pump Water Heater Integrated With Collector, Storage and Evaporation
摘要
Abstract
A novel solar heat pump water heater integrated with collector, storage and evaporation （SHPWHICSE） is presented and analyzed. By adding phase-changing materials into the collector/storage/evaporator, the solar energy can be absorbed and storied as latent heat. Calculating the storied energy according to temperature variation of the phasechange material which is chosen as paraffin, the result is that the storied energy can meet the heat load of this system. Solar got efficiency of this system is defined and compared with the direct expansion solar heat pump water heater. Experimental studies of SHPWHICSE with 150L water heating capacity are done at typical weather conditions in spring. The results indicate the system＇s COP is 5.63 on sunny days. Although on overcast or rainy days, the system＇s COP can reach 4. 13. Moreover, solar radiation intensity＇s unstable change has little influerace on the solar got efficiency and COP. Therefore, SHPWHICSE can be operating highly efficiently and stably at various weather conditions for domestic hot water.关键词
