摘　　要：介绍了一种热能驱动的新型空调温区(>16℃)的VM循环制冷机,可直接利用太阳能、工业余热或矿物燃料等的热能转换成的压力波动驱动制冷机中的工质进行膨胀制冷,并具有结构简单紧凑、振动低、运行可靠等优点。研究了制冷机冷热腔容积比,死容积和冷热排出器相位差对理论制冷量的影响,分析了各种热损失;设计了一台VM制冷机,计算了其充气压力和运行频率对实际制冷量和COP的影响,探讨了作为空调的应用前景;研究结果表明:在运行频率10Hz,制冷量达2000W时,COP可实现2.5～3,其中回热器损失占热损失主要部分。A novel VM cycle refrigerator for air-conditioning temperature zone（ 〉 16~C ） is introduced. It＇ s driven by pressure wave con- verted from heat which can be obtained by solar energy, industrial waste heat or fossil fuels. It has the advantages of compactness, low vi- bration and high reliability. The influences of volume ratio, void volume and phase difference of hot and cold displacers on theoretical cooling capacity had been studied. Also, five kinds of thermal losses were analyzed. Parameters of one VM cycle refrigerator were de- signed and the influences of charged pressure and frequency on actual cooling capacity and COP had been calculated. Moreover, the pros- pect of applications was discussed. The results show that a COP of 2. 5 - 3 at 10 Hz can be obtained with a cooling capacity of 2000W. As to thermal losses, the losses in regenerators are dominant.
