COP stands for Coefficient of Performance and is sometimes referred to as the CP or CoP and can be used to refer to the ratio of useful heating or cooling provided compared to the output required. The higher the COP, the higher the efficiency and the lower the operating costs. COP is a measure used […]
The terms air conditioner, power inverter and heat pump are sometimes referred to by different air conditioner manufacturers because air conditioners as well as having a cooling function can also provide a heating one. In the cooling industry, a power inverter normally has a higher COP (Coefficient of Performance) and can cope with a longer […]
A British Thermal Unit (BTU) is used to measure thermal or heat energy and is the amount of energy needed to raise 1 pound of water 1°F at sea level. BTU/hr is measure of the thermal or heat energy generated per hour and is a measured to used specify air conditioners. The formula for calculating BTU/hr […]
Duty of Standby is a configuration scenario where one cooling system is referred to as the ‘Duty’ system and the other as the ‘Standby’. The choice between which device acts as the Duty is known as the service. In normal operation, the Duty air conditioner is running and the Standby is does not run. This […]
R32 is a refrigerant with relatively low flammability but zero Ozone Depleting Potentual (ODP) and a lower Global Warming Potential (GWP) than traditional R22 or R410A refrigerants used in air conditioners.
R22 is a Hydrochloroflourocaron (HCFC) refrigerant used in air conditioners, process chillers and industrial plant cooling systems. R22 is an ozone depleting gas and EU legislation banned its stockholding and system topping up from 1st January 2016. As a result air conditioners using this refrigerant cannot be maintained and must be replaced.
Relative Humidity is the ration of partial pressure of water vapor in an air-water mixture to the saturated vapor pressure of water at a particular temperature. Relative Humidity is shown as a percentage and measured in: %rh. In a high temperature area the difference can be as high as 10% or greater leading to potential […]
A refrigerant is a fluid used within a refrigeration or cooling system to transfer heat. The refrigerant is circulated and absorbs heat at low temperature and pressure and transfers this heat at high temperatures and pressure. Refrigerants are typically man-made fluorocarbon compounds but there are natural refrigerants including Ammonia, CO2, hydrocarbons, water and air. Within […]
A Precision Air Conditioning (PAC) system is one designed for cooling datacentre and server room environments rather than one designed for general building (homes, commercial offices and retail). Precision Air Conditioning systems typically offer superior design and reliability and have a high ratio of sensible-to-total cooling capacity (COP).
