【摘要】 对带有中间补气功能的涡旋式压缩机理论循环进行分析,针对在不同蒸发温度下采用中间补气对涡旋式压缩机的能力、功率、排气温度及能效比的影响进行试验研究与分析。结果显示,与普通涡旋式压缩机相比,带有中间补气功能的压缩机在蒸发温度由-5℃到-20℃之间变化时,其能力提升约15%～30%,能效比提升约9%～19%,功耗仅上升约10%。更多还原

【Abstract】 Theoretical cycle of scroll compressor with second gas-injection is analyzed.The influence of second gas-injection on the capacity,power,energy efficiency and discharge temperature of scroll compressor is tested and analyzed at different evaporating temperature(-5~-20 ℃).The results show that the capacity of scroll compressor with second gas-injection increases 15%~30%,the energy efficiency increases 9%~19%,power increases merely 10%,compared with normal scroll compressor.更多还原
