太阳能溴化锂吸收式空调性能测试分析

太阳能溴化锂吸收式空调制冷是解决建筑节能降耗和太阳能建筑供能推广应用的重要途径。通过对太阳能热源系统、空调机组制冷系统的性能测试,确定了太阳能吸收式空调的制冷能力和太阳能辐照、冷冻出水温度及水循环流量之间的关系。在太阳能辐照度为700 W/m2、热源供水温度在75℃以上的工况下,溴化锂吸收式空调机组的COP达到0.65左右。太阳能空调内的真空环境和溶液管理措施是影响机组制冷性能的重要因素。

The Performance Test and Analysis of Air-Conditioning with Solar Energy Lithium Bromide Absorption

The air-conditioning and refrigeration by solar energy lithium bromide absorption is an important method for energy saving and promotion of solar energy in buildings. The relation between air-conditioning refrigeration capacity and solar radiation illumination, temperature of frozen water outlet and volume of circution water was determined by perfor- mance test of solar energy heat source system and refrigeration system of air conditioning units. When solar radiant illumination was 700 W/m2 and supply water temperature of heat source was more than 75℃, the COP of above air conditioning reached around 0.65. The vaccum environment and solution managing measures in solar energy air conditioning were important factors affecting its refrigeration performance.
