【摘要】：根据场协同原理,可通过改变制冷剂循环倍率、蒸发风机距离蒸发器的位置,来改变场协同数,提高换热效率。通过实验得出,当蒸发器进液温度为-30℃,实验中的制冷剂循环倍率从4.0增大到4.7,风机位置从21cm到36cm,换热器的场协同数存在极大值0.9。所测的降温速度、计算的COP均在场协同数达到极大值时最佳,系统达到最优。
[Abstract]:According to the principle of field coordination, the number of field synergy can be changed and the heat transfer efficiency can be improved by changing the refrigerant circulation ratio and the position of the evaporator from the evaporator. The experimental results show that the refrigerant circulation ratio increases from 4.0 to 4.7, and the fan position ranges from 21cm to 36 cm when the temperature of the evaporator is -30 鈩，
