某碳氢制冷剂替代R22节能性能比对试验研究

Research on energy efficiency of R22 and Hydrocarbon refrigerant by experiment comparison

采用现场试验测试、性能比对方法,对采用R22制冷剂的空调设备为样品1与采用某品牌碳氢制冷剂的同性能空调设备为样品2进行对比,试验得出:样品2制冷速度比采用样品1慢,但2个小时以后,制冷效果基本一致;样品2的出风温度比样品1高,平均高出4.1℃;样品2的耗电水平低于样品1,节电率达21.43%。

By the new method of experiment testing and pertormanee comparison, comparing sample 1 was the Air Conditioning Equipment that used the refrigerant R22, while the sample 2 was tire same performance Air Conditioning Equipment that used the hydrocarbon refrigerant. The result shows that ： the cooling speed of sample 2 was much slower than tire sample I, bnt cooling performance was consistent basically after running two hour＇s ; The sample 2g outlet wind temperature was much higher than the sample I g, more than 4.1℃ averagely ; the sample 2g power consumption was less than the sample l g, the power saving tale was 21.43%.
