| 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。 |

| Abstract: |
| 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. |
