Air cooler
The function of an air cooler is similar to that of an evaporator. What makes it different is the type of cooling medium it uses. An air cooler is a heat exchanger used to cool and/or dehumidify the air.
Air Handling Unit (AHU)
An Air Handling Unit (AHU) is used to re-condition and circulate air as part of a heating, ventilating and air-conditioning system.
Airlift pump
The airlift pump – also called mammoth pump – exploits the increase of the oxygen intake in water under pressure. At the same time, rising air is used to lift – and therefore circulate – water. This makes the mammoth pump suitable for aerating and circulating large volumes of water. An airlift pump is often used in situations where maintenance needs to be kept to an absolute minimum.
Aluminium
Pure aluminium is a light, soft metal with a density of about a third of that of steel. Pure aluminium has a high electrical and thermal conductivity.
Ambient condition
“Ambient conditions” is a set of parameters used by designers for dimensioning ventilation and cooling systems. Ambient conditions typically include temperature, humidity and air pressure.
ATEX
ATEX is an abbreviation of a French term used to denote an explosive atmosphere.
Axial fan
An axial fan is a type of fan where both motor and wings are mounted directly on the axle. When the axle and the wings rotate, it results in a current parallel with the axle.
Back-to-back seal
A back-to-back seal describes two shaft seals mounted back-to-back to provide a higher level of safety and reliability.
BACnet
BACnet is a data communication protocol for Building Automation and Control Networks. It is a standardised technology for building automation and supports a variety of specific physical network standards, which makes it ideal for use on all automation levels.
Balance point
In any thermal heat exchange process, a mixture of two energy flows will result in a new stage or phase called the balance point. Here, a common temperature, humidity or enthalpy is reached.
