摘要:

将单螺杆水蒸汽压缩机应用于机械蒸汽再压缩热泵(MVR)系统,并对该压缩机的工作过程进行分析;在不同蒸发温度的工况下,对采用闭式和开式循环的MVR系统进行实验研究.实验结果表明,当蒸发温度高于80 ℃时,压缩机的容积效率超过0.73,绝热内效率大于0.5;系统的实际COP最高达12.5,实际单位能耗蒸发水量最高可达20 kg/(kW·h);充分显示了单螺杆水蒸汽压缩机驱动MVR系统的高效节能特性.

Abstract:

Single screw water vapor compressor is applied in the mechanical vapor recompression heat pump (MVR) system. Analysis of the working process of the compressor is carried out. Experiments for the MVR systems with closed cycle and open cycle are performed under different evaporation temperature conditions. The results show that the volume efficiency of the compressor is larger than 0.73 and the adiabatic efficiency is larger than 0.5 when the evaporation temperature is higher than 80 ℃. The largest practical COP of the system reaches 12.5 and the highest actual SMER reaches 20 kg/(kW·h) in the present experiments. The high efficiency and energy-saving features of the MVR system driven by single screw water vapor compressor are fully shown in this study.

Key words: single screw water vapor compressor, MVR, efficiency of the compressor, COP, SMER
