摘要
为探究压缩机的倒置性能,搭建性能实验台,研究制冷剂充注量对制冷性能的影响。结果表明:当制冷量及其他条件一定时,随着充注量的增加,压缩机排气温度和功率大于正立的值,制冷COP(coefficient of performance)小于正立的值。最佳制冷剂充注量150 g下的最大制冷COP值为3.2。压缩机倒置后系统性能良好,该系统是"重力无关"系统。压缩机倒置性能实验可为热泵空间应用提供实验参考价值。
Compressor is the core component of the vapor compression heat pump. In order to explore the inverted performance of the vapor compression heat pump compressor, compressor is inverted and performance laboratory bench is built to study the influence of refrigerant charge on system performance. Experimental results show that compressor discharge temperature and compressor power increase with the amount of refrigerant charge under conditions of constant cooling capacity and other conditions. The coefficient of performance （COP） is less than the value obtained when compressor is upright. The maximum cooling COP value of 3.2 under 150 g is got. The cooling performance is good that the vapor compression heat pump can be considered as gravity-independent. Experiments of vapor compression heat pump with compressor inverted provide valuable reference value for space application.
