摘要:
提出了一种同时供冷、供热的CO2双级压缩热泵循环,它能够实现冷热量的同时独立调节;并通过实际案例,理论分析了不同中间温度、热水加热器入口水温、回热器出口过热度以及制冷剂质量流量系数下新循环的性能,考察了高压压缩机最佳排气压力的影响因素
Abstract:
A CO2 two-stage compression heat pump cycle is proposed. It can not only recycle waste heat the generated by refrigeration, but also supply cooling and hot water at the same time according to the users need. Theoretical an alysis indicated that the intermediate temperature、inlet water temperature of the hot water heater、the superheat at the outlet of the regenerator and the refrigerant mass flow coefficient all exert their have influence on the new cycle properties. In addition, the effect factors of the high pressure compressors optimum exhaust pressure are discussed
