GEO VENTS system description and structure
The air duct system is laid below the freezing point serves as a heat exchanger between the ground and the air moved through these air ducts. The air that is moved in the air duct is heated or cooled by the ground depending on the season of the year.
Composition set (10)
GEO VENTS system comprises:
- The ground heat exchanger for intake air pre-heating or pre-cooling.
- The VENTS VUT air handling unit with heat exchanger. The thermal energy gets transferred from the extract air to the warmed up supply air from the geothermal heat exchanger.
- Air ducts for air transportation into the premise.
- Grilles and swirl diffusers for air distribution in the room.
The GEO VENTS system advantages:
- Pre-heating of the intake air during the winter time as well as cooling and dehumidification of the supply air during the summer time. Significant reduction of operating costs.
- The VENTS VUT ventilation unit with heat exchanger provides heat transfer from the exhaust air to the supply air. Energyefficient EBM electronically-commutated motors increase the system energy efficiency.
- High system inertness. Whereas the outside air temperature can quickly change the ground temperature at 1,5 m depth has a permanent value as well as the supply air temperature at the heat exchanger inlet..
SYSTEM ARRANGEMENT EXAMPLE IN BUILDINGS WITH BASEMENT FLOOR
Mounting the geothermal ventilation system in a building with basement floor is always combined with mounting of the basic system elements such as condensate collecting and drainage unit, by-pass valve, reducers and air handling unit with heat recovery in the basement floor.
SYSTEM ARRANGEMENT EXAMPLE IN BUILDINGS WITHOUT BASEMENT FLOOR
Mounting the geothermal ventilation system in a building without basement floor is always combined with the manhole with the condensate collecting and drainage unit. The air handling unit and its components need to be installed in a specially designed place.
Installation scheme of GEO VENTS in buildings without basement floor
The air duct for ground application enter the building through a hole in a wall below of the ground level. The air handling unit is placed in a basement.
