Evaporative air cooler
1 Scope
This document specifies the terms and definitions, classification and model designation, requirements, test method, inspection rules, marking, packaging, transportation and storage of evaporative air coolers for household and similar use (hereinafter referred to as "air cooler").
This document is applicable to the evaporative air coolers for household and similar use with single-phase rated voltage not exceeding 250V and other rated voltage not exceeding 480V.
This document is not applicable to:
——air coolers but designed exclusively for industrial purposes;
——air coolers intended to be used in locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapor or gas);
——air coolers with rated output air volume exceeding 1,500m³/h.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
evaporative air cooler
an apparatus that uses the principle of evaporation and heat absorption of water to mechanically ventilate air through a moist cooling pad, thereby lowering the temperature of the treated air
3.2
cooling pad
a substance that provides an evaporation interface and increases the area of water-air contact
3.3
air flow
volume of air delivered by an air cooler per unit of time under specified conditions
Note: It is expressed in m3/h. The rated output air flow is specified by the manufacturer.
3.4
evaporative quanlity
amount of water consumed per unit time by the air cooler during evaporative cooling operation under specified conditions
Note: It is expressed in mL/h or L/h. The rated evaporation is indicated by the manufacturer.
3.5
energy efficiency ratio
ratio of the sensible heat taken away by the air flow per unit time to the input power of the air cooler when the air cooler undergoes evaporative cooling under the specified conditions
Note: It is expressed in W/W.
3.6
rated water tank capacity
amount of water to be contained when the tank is filled to the highest indicated water level prescribed by the manufacturer
Note: It is expressed in L. The rated water tank capacity is indicated by the manufacturer.
3.7
standby mode(s)
when connected to the main power, the air cooler provides one or more of the following user-oriented functions or protection functions, which is a continuous mode for any product:
——other modes (including active mode on or off) can be triggered by triggering remote switches (including remote control), internal sensors and timers;
——continuous function: information or status display including clock;
——continuous function: sensor-based function.
4 Classification and model designation
4.1 Product classification
By function:
——Single cooling type: with code omitted;
——Heating and cooling type: with code indicated by R.
