（1）完善的程序控制系统
Improved program control system
机组控制元件全部采用国际品牌，运用可编程控制器及带背光中文显示器，对机组的恒温恒湿精度、过滤效果、可靠运行、故障保护进行全自动控制，机组运转可靠稳定.
The controlling components of the unit all adopt the international brands, and make the use of programmable logic controller and Chinese display with backlight. It can automatically control the precision of the constant temperature and humidity unit, filter effect, reliable operation and fault protection. Thus, the operation of the unit is stable and reliable.
（2）免维护，节省成本
Maintenance-free, cost-saving
机组根据设定的参数与室内外环境温度值作比较，智能化选择运行机组，由室内外温差判定运行换气送风系统，进/出风压差判定运行除尘装置和除尘排风系统，利用换气送风系统把室外的低温空气通过双级空气过滤后送入室内，从而达到洁净、节能、降温效果，实现免人工维护的效果，减免维护产品时间及成本。
According to the comparison of the set parameters and the indoor and outdoor temperature, the unit operation can be selected intelligently. The aeration and air supply system can be determined by the difference between the indoor and outdoor temperature. The dust-removing device and the dust-removing air-exhausting system can be determined by the pressure difference between inlet and outlet air. By using the aeration and air supply system, the low temperature air outside can be sent to inside through the double stage air filter, in order to achieve the clean, energy-saving, refrigerating effect. Thus, the users are free of artificial maintenance and reduce the maintenance time and cost.
（3）安装简单，操作方便
Simple installation, convenient operation
免工具设计，安装卸载时只需将面板卡簧轻轻压紧，就能轻松自如的拆下或装上面板，满足不同环境安装需求，方便快捷，省时省力。
It is free of the tool design. By gently pressing the clamp spring, the panel can be easily installed or removed, satisfying installing requirements of different environment, which is convenient, efficient, and energy-saving.
