摘要
通过热力学分析,运用REFPROP软件对多功能热泵洗碗机在4种工况下运行时的能效等级指标COP进行研究,结果表明:4种工况下系统的COP均在3.2以上,满足能效等级指标要求。将传统电加热式洗碗机与多功能热泵洗碗机的能效及环保效益、运行费用进行对比发现,在一次运行能耗为40 kW·h情况下,多功能热泵洗碗机的标准煤热能消耗量、一个循环过程二氧化碳排放量和运行费用分别为1.24×10~5 kJ,10.55 kg和15.49元,均低于传统电加热式洗碗机。
The energy efficiency rating indexes COP of the multi-functional heat pump dishwasher under four operating conditions are studied by thermodynamic analysis. The results show that under all four operating conditions, the COP of system is above 3.2, which meets the energy efficiency rating index. The energy efficiency and environ- mental benefits, operation cost of traditional electric heating dishwashers and multi-func- tional heat pump dishwasher are compared, the results show that for multi-functional heat pump dishwasher, the energy consumption of standard coal, the carbon dioxide emissions and operation cost of one cycle are 1.24 x 105 kJ, 10.55 kg and 15.49 yuan respectively under the condition of primary operation energy consumption of 40 kW·h, which are all lower than those of traditional electric heating dishwasher.
