Summary

In order to improve the performance of the heat pump system under large temperature difference, this paper proposed a triple-loop heat pump ventilation recovery scheme, and an energy recovery performance test platform was set up based on the exhaust energy recovery of the building air-conditioning system. The performance of the single-loop and triple-loop heat pump systems were tested under different outdoor temperature conditions in winter and summer through experiments. The results showed that the overall performance of the triple-loop system was significantly higher than the single-loop under all operating conditions. Under winter conditions, the COP of the triple-loop system had reached to 11.19, when the indoor and outdoor temperature difference was 40 °C, and the COP of the triple-loop was 54.8% higher than the single-loop. Under summer conditions, the growth rate of the COP of the triple-loop system had reached to 89.8%, when the temperature difference was 13 °C, and the COP of the triple-loop was 74.6% higher than the single-loop.
