HCFC (Hydrochlorofluorocarbon)
CFC and HCFC refrigerants contribute to the breakdown of the ozone layer and the greenhouse effect. CFC is an abbreviation of chlorofluorocarbon; HFC is an abbreviation of Hydrochlorofluorocarbon. They describe the molecules’ atom content.
Header
A header is a manifold, the purpose of which is to uniformly distribute coolant in pipe circuits in air coolers, dry coolers, evaporators and condensers.½
Heat pump
A heat pump is a system that can both cool, heat, and dehumidify air in a room, depending on the demand. These systems have a reversible heat transfer cycle.
Heat rejection
Heat rejection is the excess heat from a cooling system which is removed by the condenser/cooling tower. Heat rejection is the total amount of heat energy which is transferred from the cool side to the warm side, plus the work carried out by the compressor.
Heat transfer fins
Fins are used on all air coolers, dry coolers, evaporators
HFC (Hydrofluorocarbon)
HFC as a refrigerant does not contribute to the breakdown of the ozone layer, but contributes to the greenhouse effect. HFC is an abbreviation of hydrofluorocarbon, and describe the molecules’ atom content.
Hygienic designed manifold
Grundfos Hydro booster sets are not designed for the pumping of sterile liquids, but their construction and the choice of materials make them an ideal solution for secondary processes in hygienic applications such as pumping of potable water.
Inlet pressure
Inlet pressure describes the pressure available where the suction pipe meets the booster pump.
Lambda value
The heat conductivity of a material is known as its lambda value. The lambda value is used for thermal calculations on buildings and thermal components.
Latent cooling load
Latent cooling load is a measure of the amount of energy that is necessary to dehumidify the air in a building, for example, regardless of the outdoor humidity. Cooling load needs to be considered when a cooling system is being dimensioned.
