摘要
以某AQR-TZ42k型号冰箱为研究对象,对不同毛细管流量条件下的节能效果进行了对比研究.实验研究发现:使用12 L/min、7 L/min、5 L/min毛细管流量分别进行测试,当毛细管流量为5 L/min时,整机稳定段耗电量最低为0.70 kW·h/24 h,随着流量增加,耗电量分别升高3％、14％;采用双毛细管分时控制,使用5 L/min(低负荷)+5 L/min(高负荷)、7 L/min(低负荷)+7 L/min(高负荷)、12 L/min(低负荷)+12 L/min(高负荷)毛细管流量分别进行测试,当采用5 L/min(低负荷)+5 L/min(高负荷)组合时,冰箱(含化霜段)耗电量最低为0.80 kW·h/24 h,随着流量增加,耗电量升高6％、19％.实验结果说明,通过分时控制毛细管流量,可有效提升冰箱节能效果.
Abstract
A comparative study was conducted on the energy-saving effect of a certain AQR-TZ42k refrigerator under different capillary flow conditions.The experimental study found that:using 12 L/min,7 L/min,5 L/min capillary flow were tested,when the capillary flow is 5 L/min,the minimum power consumption in the stable section of the whole machine is 0.70 kW·h/24 h,with the increase of the flow,the power consumption increased by 3％,14％respectively.Dual capillary time sharing control,the capillary flow rates of 5 L/min(low load)+5 L/min(high load),7 L/min(low load)+7 L/min(high load),12 L/min(low load)+12 L/min(high load)were used for the test,respectively.When the combination of 5 L/min(low load)+5 L/min(high load)is adopted,the power consumption of the whole machine(including the defrosting section)is the lowest 0.80 kW·h/24 h,and the power consumption increases by 6％and 19％with the increase of flow.The experimental result proves that the energy saving effect of the refrigerator is improved by controlling the capillary flow rate by time sharing.
