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.
“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.
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.
BTU (British Thermal Unit)
The British thermal unit (BTU) is a unit of energy used in the power, steam generation, heating and air-conditioning industries. In scientific contexts the BTU has largely been replaced by the SI unit of energy, the joule [J].
A buffer tank is a storage tank used on the cold user side of an air-conditioning system. The tank is used as storage to cover peak loads or in situations when a surge in demand exceeds the capacity of the cooling system.
A butterfly valve is from a family of valves called quarter-turn valves. The butterfly is a metal disc mounted on a rod. When the valve is closed, the disc is turned so that it completely blocks off the passageway.
CFC and HCFC refrigerants are detrimental to the breakdown of the ozone layer and the greenhouse effect. CFC is an abbreviation of chlorofluorocarbon; HCFC is an abbreviation of Hydrochlorofluorocarbon. They describe the molecules’ atom content.
