这里列出的是具有不同隔热层厚度的不同大小的家用冻结器和冰箱的隔热层损耗的计算公式。对具有通常负荷和压缩机效率的,连同如门的周围的其它损耗在内的动力消耗,也作了估算。计算表明;用增加隔热层的办法节约动力的效果,冷结器只有20％,冰箱只有30％。代号说明: L 边缘长度,米 L_1 边缘的内部长度,米 A_M 隔热层的平均面积,米~2 V_1 内部容积,Ⅰδ隔热层厚度λ隔热层的热传导=0.018
Listed here are the formulas for calculating the insulation loss for home freezers and refrigerators of different sizes with different thickness of insulation layer. Power consumption with normal load and compressor efficiency along with other losses such as around the door has also been estimated. Calculations show that with the addition of insulation to save power, the cooler is only 20% and the refrigerator is only 30%.
