3 Terms and definitions
The following terms and definitions apply to this document.
3.1
Air cooler aircooler
A heat exchanger that uses air as an intermediate medium to exchange heat between a refrigerating space and a refrigerant. The cooler is composed of heat exchangers and accessory equipment
a device.
3.2
Dry air cooler dry-typeaircooler
Air Cooler During operation, the heat exchange process is not an air cooler that is performed by injecting liquid refrigerant.
3.3
External static pressure loss externalstaticpressureloss
Static pressure loss caused by air flowing through the air duct and other external components of the air cooler.
3.4
Forced circulation air cooler forcedcirculationaircooler
An air cooler that circulates air by mechanical means.
3.5
Free conveyor air cooler freedelivery-typeaircooler
Contains no air ducts or other components that are resistant to airflow, absorbing air from the cold room and discharging it into the cold air cooler.
3.6
Total cooling capacity grosstotalcoolingeffect
The amount of heat absorbed by the refrigerant. The sum of the net total cooling capacity and the thermal equivalent of the work required to operate the chiller.
3.7
Internal static pressure loss internalstaticpressureloss
Air pressure loss caused by air flowing through a factory-assembled cooler.
