摘要
传统的冷却除湿通常采用带一次回风的空调箱系统,其存在大量的冷热抵消,采用二次回风空调箱系统能够较好的避免冷热抵消。通过对一医疗器械厂房采用的一二次回风系统在除湿过程中所消耗的电量进行计算比较,得出了二次回风在一个除湿周期的节电量。同时计算二次回风系统的动态投资回收期以及指出了该系统的适用范围。
It is usually when dehumidifying using the primary return air system of AHU, heating load offsetting the cooling load can not be avoided in this system. By using the secondary return air system of AHU can avoid the heating load offsetting the cooling load. Here compare the power consumption between primary return air system with secondary return air system in dehumidification, calculate the power saving during one dehumidification period. Meanwhile, dynamic investment pay-back period is calculated and the using scope is pointed out.
