为了简化双回路热泵通风余热回收系统，本文设计了一种新型的双缸独立吸气口和两个独立排气口的旋转压缩机，并将其用于驱动余热回收系统。因此，通过双环压缩循环形成了接近洛伦兹循环的系统循环。搭建了新型压缩机换气余热回收热泵系统实验台，进行了系统性能试验。实验结果表明，与传统的单环路热泵系统相比，冬季试验条件下双环路系统的COP可提高17.1%。在室外温度−为5℃、室内温度为20℃的条件下，双回路系统的COP可达10.21.夏季试验条件下，双回路系统的COP比传统系统高出33.47%。在室外温度为40℃、室内温度为27℃的条件下，双回路独立压缩系统的COP可达4.69。采用独立吸、排气口的新型压缩机，可大大提高热泵通风余热回收系统的性能水平。
To simplify the dual-loop heat pump ventilation heat recovery system, a new type of dual-cylinder rotary compressor with two independent suction ports and two independent discharge ports was designed and used to drive the heat recovery system in this paper. Thus, a system cycle approaching the Lorentz cycle was formed by dual-loop compression cycles. A test bench of heat pump system for ventilation heat recovery with a novel compressor was built to carry out system performance experiment. Experimental results showed that the COP of the dual-loop system under winter test conditions could be increased by 17.1% compared with that of the traditional heat pump system with a single loop. The COP of the dual-loop system could reach 10.21 under the outdoor temperature of −5°C and the indoor temperature of 20°C. Under summer test conditions, the COP of the dual-loop system was up to 33.47% higher than that of the traditional system. Under the outdoor temperature of 40°C and the indoor temperature of 27°C, the COP of the dual-loop independent compression system could reach 4.69. The performance level of the heat pump system for ventilation heat recovery could be greatly improved using the novel compressor with independent suction and discharge ports.
