Evaporative condenser
An evaporative condenser is used to remove excess heat from a cooling system when the heat cannot be utilised for other purposes. The excess heat is removed by evaporating water.
Evaporator
An evaporator is used in a cooling system. An evaporator absorbs heat from the surroundings, for example by cooling the surrounding air.
Expansion
Expansion is an expression used in a cooling plant. It relates to the temperature and the process that brings the refrigerant from the condenser side to the evaporator side in the cooling plant.
Fan
A fan is a device with wings or an impeller that rotates by means of an electric motor. Upon the rotation of the wings or impeller, air is set in motion. The rotation causes the mechanical work to be transferred to the air.
Fan coil
A fan coil is used to heat or cool down air in many different types of locations, for example; in production areas in the food industry, warehouses, offices, supermarkets, etc.Since it does not have any ductwork, a fan coil unit is used to control the temperature only in the space where it is installed.
Fieldbus
A fieldbus is the information highway that connects the components in a BMS system to allow monitoring and controlling of air-conditioning systems, heating systems, lighting systems, ventilation, wastewater systems etc.
Fin spacing
Fin spacing is the distance between fins which are used on fan coils, air coolers, dry coolers, evaporators and condensers. Increasing or decreasing fin spacing has a major impact on the coil performance.
Frequency converter
A frequency converter is an electric device that converts a current with one frequency to a current with another frequency. The voltage is normally the same before and after frequency conversion. Frequency converters are normally used for speed regulation of motors used to drive pumps and fans.
GENIbus
GENIbus is an open data communication protocol developed and maintained by Grundfos. It is used to connect Grundfos pumps to pump controllers or via gateways to monitoring and supervisory computers in Building Management Systems and SCADA systems.
Geometric Height
In a boosting system, the geometric height is the physical height that the water has to be lifted, in order to reach the consumer.
