摘　　要：地下工程的大量涌现,使得节能效果好、效率高的并联型调温除湿机得到了广泛的应用,三通比例调节阀是并联型调温除湿机的关键部件,其动作特性对机组性能具有重要影响。在构建双冷凝器并联型调温除湿系统的基础上,测试了制冷剂流量三通比例调节阀开度变化对机组性能的影响,结果表明:1)可以通过调节三通比例调节阀的开度实现送风温度的连续调节,三通阀作用区域为开度30%～80%;2)三通阀开度变化对系统除湿量有影响。阀门开度在50%～65%时,系统除湿量最大,输入功率最小,具有最高的单位功率除湿量;3)通过调节阀门开度,可以实现制冷剂流量的调节,制冷剂流量最大值出现在阀门开度为50%～70%区间内。这些调节方法对提高并联型调温除湿机效率具有一定意义。With the rapid growth of underground projects,the temperature control dehumidifier with parallel condensers has been widely used for its energy saving and high efficiency.The influence of the 3-way modulating control valve in temperature control dehumidifier with parallel condensers on unit cooling,dehumidifying and supply air temperature was studied,The result shows that：（1） the continuous temperature adjustment could be achieved by adjusting the opening degree of the three-way valve.The effective region of the three-way valve was between 30% and 80%;（2） the opening degree of the three-way valve has influence on the dehumidification of the unit;when the open degree is between 50% and 65%,the unit has the lowest value in input power and highest value in dehumidification;（3） the refrigerant＇s flow rate could be modulated by modulating the opening degree of the 3-way valve,and the highest flow appeared when the opening degree is between 50% and 70%.The ways of adjustment are very useful for improving the efficiency of temperature control dehumidifier with parallel condensers.
