3 Terms and Definitions

The terms and definitions defined in GB/T 16803 and the following terms and definitions apply to this document.

3.1

The driving force is the water vapor transfer potential energy possessed by the difference between the partial pressure of water vapor in the air and the corresponding saturated water vapor pressure (hereinafter).

(abbreviated as "dry air energy") is an air conditioning unit that drives water in the evaporative cooler to evaporate and exchange heat, providing cold air or simultaneously providing cold air and chilled water.

3.2

An air-cooling heat exchanger that uses dry air energy to drive water evaporation to cool the air, and the produced cold air is in direct contact with the water.
