摘要：

The present study conducted experiment on heating and reverse-cycle operation using a low-temperature heat source. A 20 kW scale water switchable experimental device is built to develop a river water heat pump system with a heat source mix technology that can provide cooling and heating energy irrespective of the temperature characteristics of the heat source. Even at 4 degrees C and 4.5 degrees C, the river water heat pump demonstrates good efficiency, with COPh values of 3.05 and 3.15, respectively. The reverse-cycle operation experiment is conducted using three different methods, switching the water side valve momentarily each time the evaporator's water output temperature reaches -1 degrees C. In the reverse-cycle operation, the inlet and outlet temperatures of the evaporator circulating water are compensated to prevent supercooling of the plate. An optimal operation control pattern to prevent supercooling is determined to be possible through reverse-cycle operation.
