摘要:
介绍并研究了一种新型集热/蓄能/蒸发一体化太阳能热泵热水器系统(SHPWHICSE).该装置将真空管集热器、蓄能容器和蒸发器集于一体,通过相变潜热吸收并储存大量太阳能.根据相变材料(石蜡)在吸、放热过程中温度的变化计算蓄热量,确定相变材料中储存的热量能够满足系统热负荷.定义了一体化太阳能热泵系统的得热效率,并和直膨式太阳能热泵热水器得热效率进行比较.在春季典型工况下对容量为150 L的SHPWHICSE进行实验研究,结果表明:晴天工况下,系统COP可达5.63;即使阴雨天,COP也可达4.13;太阳辐射强
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 influence on the solar got efficiency and COP. Therefore,SHPWHICSE can be operating highly efficiently and stably at various weather conditions for domestic hot water.
