II -Cooling Pad
The Pad is the core of cooling system. It is made of corrugated paper with special technique processing, corroding-resistant, higher wet strength and long life.

III-Auto Controller

The controller can calculate the current target temperature

according the four different time period a day and corresponding temperature

requirement. The process is as follows:

Detect the indoor temperature------Calculate the difference between the current

temperature and the target one------Obtain the cooling requirement value after

further PI calculation------Control the work of Fan & Pad System.
