太阳能辅助热泵冷热水一体机

Solar-assisted heat pump hot and cold water integrated machine

提出一种太阳能辅助热泵冷热水一体机系统,可以满足夏季供冷、冬季供热、全年提供生活热水的需求。系统采用冷凝热回收、冷凝水预冷、化霜储液器等技术,强化除霜效果,提高系统总效率。实际性能测试结果表明:在室外空气干球温度35℃的夏季工况下,太阳能辅助热泵冷热水一体机的综合COP值达到4.10;在室外空气干球温度7.5℃的冬季工况下,其综合COP值达到4.13。

One solar-assisted heat pump hot and cold water integrated machine system is proposed,which can meet the demand of cooling in summer and heating in winter,and domestic hot water supply throughout the year.The system uses some technologies such as condensing heat recovery,condensed water pre-cooling and defrosting reservoir,so as to enhance the defrosting effect and improve the overall system efficiency.The test results of actual performance show that under the summer working condition at outdoor dry-bulb temperature of 35℃and the winter working condition at outdoor dry-bulb temperature of 7.5℃,the comprehensive COP values of the solar-assisted heat pump hot and cold water integrated machine reach 4.10 and 4.13 respectively.
