A direct system is a heating system where the heat emitters are directly connected to a boiler or district heating system. This means, that the district heating water is supplied directly to the consumer’s radiators or other heat surfaces.
A discharge de-superheater can be used in a cooling plant to produce domestic hot water. This is possible when there is a simultaneous demand for both cooling and hot domestic water in the building.
Discharge flow is the assumed flow from discharge units. Normally, it refers to the flow entering a pumping station. It is typically expressed in litres per second or cubic metres per hour.
