摘要
介绍了一种自行设计的小型水冷式跨临界CO2热泵热水器试验系统,研究了在蒸发器侧冷冻水流量不变,改变气冷器侧冷却水流量的情况下,相关系统性能的变化规律。试验结果表明:试验条件下,在流量为0.0243kg/s时,平均制热量最大,约为1570W;系统制热COPh值随气冷器冷却水流量的增加而升高,最大COPh值为2.84;跨临界CO2热泵热水器可用于制取较高温度的热水。
A small self-designed water source heat pump water heater system with transcritical CO2 cycle was presented. When the evaporator side chilled water flow rate was unchanged and the gas cooler side cooling water flow rate was changed, the changes of system＇ s performance were studied. The experimental results show that ： in the experimental conditions, when the flow rate is 0.0243kg/s ,the average maximum heat was 1570W. The system＇ s COPh increased with the increase of flow rate of gas cooler＇ s cooling water and the maximum COPh was 2.84. It seems that heat pump water heater with transcritical CO2 cycle could get high- temperature hot water.
