摘要(Abstract):

房间空调与供热水耦合的CO2 跨临界循环系统 ,充分利用CO2 作为自然工质的独特性能 ,利用气体冷却器放出的热量提供所需生活热水。该系统结构紧凑 ,而且能够满足制冷、制冷 +热水、热水、制热、制热 +热水五种工况需求。通过对其进行技术可行性、全年能耗和综合性能系数进行分析 ,结果表明房间空调 +热水的CO2 耦合系统在能源利用、环境安全和经济运行等方面都具有优势和潜力。
CO_2 transcritical cycle system combined room air-conditioner and heat pump water-heater can offer enough living hot water by recovering the heat of gas-cooler.The system structure can be very compact with the help of character advantages of CO_2.The system can satisfy such needs as cooling,cooling and hot water,hot water,heating,heating and hot water.Through analysis on the technology feasibility,annual power consuming and comprehensive coefficient of performance,it indicates that the CO_2 transcritical cycle system combined room air-conditioner and heat pump water-heater is preponderant and potential in effectively utilizing energy,environment protection and economical operation.
