海水源热泵系统供暖实验研究
|
摘要
基于毛细管前端换热器海水源现场实验,进行供暖实验。经实验测试结果表明,沙层土壤温度越高,则机组进水温度也越高,单位管长换热量也就越大,热泵系统COP也就越大;实验工况下,毛细管单位片面积换热量平均值为27. 2 W/m2,热泵系统COP平均值2. 35;浅层海床沙层土壤温度恢复能力较强,毛细管换热器对周围土壤热环境影响较小。
Based on the experiment of capillary front heat exchanger of seawater source,the heating is tested. The experimental results show that the higher the sand temperature is,the higher the inlet water temperature of the unit is,the greater the heat transfer of per unit tube length is,therefore the greater the COP of the heat pump system is. Under the experimental conditions,the average of heat transfer of per unit area of the capillary tube is 27. 2 W/m2,and the average COP of the heat pump system is 2. 35. The capillary heat exchanger has less influence on the surrounding of soil thermal environment.
