摘要：
In order to investigate the effect of gravity direction on the compressor lubrication of space vapor compression heat pump, the experiments for the scroll compressor with various inclination angle have been done in this paper. The results show that the heat pump system can keep working well in all inclination angles, and the gravity independence of scroll compressor is well. In the cooling power of 2500~3500 W, the maximum variation of evaporation temperature is 1.3℃. The maximum relative change in the temperature difference between evaporation and condensation and coefficient of performance (COP) are 3.2% and 6.3% respectively. The performance of the compressor is associated with quantity of circulating oil. When the compressor is inversed in these experiments, settled lubrication oil circulates together with the refrigerant through the heat pump system, thus improving the performance of compressor. © 2016, Editorial Dept. of JA.
