Cold store
A cold store is a refrigerated area for cold storage, a refrigerated building, or an area for keeping goods, especially food, in cold conditions to preserve them.
Cold water
Domestic cold water covers the water that is used in a home for showering, cooking, etc. This water comes either from a water supply system delivering water to many households, or from a private well.
Colebrook-White
Colebrook-White's formula can be used to determine the friction coefficient (l) of a turbulent flow. The formula is normally used to create diagrams where the friction coefficient can be read.
Compensator
A compensator can be built-into a heating system to absorb pipe linear expansion as an alternative to an expansion loop.
Compressor
A compressor is the heart of a cooling system. It increases the pressure of a gas by reducing its volume.
Condensate pump
A condensate pump is used to pump condensed water in cooling systems.
Condenser
A condenser is used in a cooling system. A condenser removes heat from cooling medium that flows through it. The cooling medium can be one of several coolants.
Condensing boiler
A condensing boiler is provided with a condenser, by which the water vapour produced by the burning of gas or oil in the boiler, condenses back into liquid water - hence the name condensing boiler. The energy contained in the vapour, would without a condenser, normally discharged to the atmosphere through the flue.
Condensing temperature
The condensing temperature is the temperature at which a cooling medium changes phases from a gas to a liquid.
Conductivity transmitter
Conductivity transmitters measure the electrical conductivity in a liquid. This is done in order to avoid excessive salinity, which can cause corrosion in e.g. air-conditioning systems.
