吸气/补气独立压缩房间空调器的运行特性及应用效果

Operating characteristics and application effects of room air conditioners with independent compression of suction and supplement gas

房间空调器作为住宅建筑最大的耗电量设备之一,随着人民对生活品质的追求,其空调器的保有量和总能耗仍将继续增加,因此,提高空调器的能效是节能减排、加速生态文明建设的重要措施。针对长江流域的特殊气候和用户对空调的需求,分析了采用R32制冷剂的吸气/补气独立压缩循环房间空调器的运行特性;获得了空调器的设计、匹配及运行控制的关键参数;并以能效最佳为目标,研发了空调器产品,实验结果表明:相比于常规单级压缩空调器,吸气/补气独立房间空调器的APF提高了6%,高温与低温工况的制冷(制热)能力提升了5%,且其排气温度降低了2~7℃。

Room air conditioners are one of the largest power-consuming devices in residential buildings.With people’s pursuit of quality of life,the number and total energy consumption of air conditioners will continue to increase.Therefore,improving the energy efficiency of air conditioners is an important measure to save energy,reduce emissions,and accelerate the construction of ecological civilization.In view of the special climate and users’demand for air-conditioning in the Yangtze River Basin,analyzes the operating characteristics of room air conditioners with independent compression cycle of suction and supplement gas using R32 refrigerant.And obtains the key parameters of air conditioner design,matching and operation control.Aiming at the best energy efficiency,the air conditioner product has been developed.The experimental results show that:Compared with the room air conditioner with single-stage compression,the room air conditioner with independent compression of suction and supplement gas can increase the APF by 6%,increase the cooling(heating)capacity of high temperature and low temperature conditions by 5%,and reduce the exhaust temperature by 2~7℃.
