Common Terminology For Air Conditioning

- Apr 09, 2019-

1. Nominal cooling capacity

The amount of heat that the air conditioner removes from the space area or the room under nominal cooling conditions is called the nominal cooling capacity per unit time.


2, nominal heat

The amount of heat that the air conditioner releases to the space area or room under nominal heating conditions per unit time.


3. Energy efficiency ratio (EER)

The amount of cooling capacity per unit of motor input power. It is the ratio of the cooling capacity to the cooling power when the air conditioner is cooling, in units of W/W. The national standard stipulates that the energy efficiency ratio of the 2500W air conditioner is 2.65; the energy efficiency ratio of the 2500W to 4500W air conditioner is 2.70.


4, performance parameters (COP)

The performance parameter COP value of the refrigeration compressor, that is, the cooling capacity per unit of shaft power.


5. Common air conditioning unit and conversion:

One kilowatt (KW) = 860 kcal (Kcal / h).

A large card (Kcal/h) = 1.163 watts (w).

1 cold ton (USRT) = 3024 kcal (Kcal / h).

1 cold ton (USRT) = 3517 watts (W).
