摘　　要：在非夏季外气温度较低时,若采用风冷式冷凝器制冷设备的冷负荷不变时,冷凝压力会相应偏低。本文提出一种基于冷凝风机变频调速的冷凝压力调节方法,并通过试验进行了研究。试验结果表明,该方法在外气温度较低时,不仅能够合理地调节冷凝压力,还具有较大的节能潜力。If it is not in summer and the ambient temperature is lower,condensing pressure will be lower than the normal value when the thermal load of a refrigeration plant with air cooled condenser is constant.In this paper,a regulation method of condensing pressure was proposed based on variable frequency speed regulation of a condenser fan.By experiments,it is found that the method can not only regulate the condensing pressure properly when the ambient temperature is lower,but also gain a great energy-saving effect.
