Heating register

from Wikipedia, the free encyclopedia

The heating register is a recuperative heat exchanger and is used in building air conditioning. In ventilation and air conditioning systems , it increases the temperature to treat the air.

The heating register can be used for different tasks:

Preheater
  • raise the temperature of the fresh outside air to +5 ° C in winter to prevent frost damage to downstream water-filled system components.
  • raise the air temperature by 2 to 3 K for filter  drying so that fog or rain droplets carried by the air do not soak the air filter to be protected .
  • raise the air temperature before evaporative humidification in order to achieve better moisture absorption in the air.
Heater
  • temper the fresh outside air so that the supply air is not too cold into the rooms.
  • heat the supply air in such a way that the static heating of the rooms is relieved or replaced.
Reheater
  • are downstream of a cooler and raise the air temperature behind a dehumidification process so that the supply air is not too cold into the rooms.
  • are downstream of a heat recovery system in order to raise the supply air temperature above the extract air temperature.
  • are downstream of the central air treatment and provide different temperatures for different supply air zones.

The term was also used for an extension of the stove pipe for wood and coal room stoves . This expansion channeled the smoke to give off more heat before it was channeled into the chimney . One could also speak of a downstream heating surface.
