Geothermal pre-conditioning - what it is?

The Geothermal pre-conditioning is a ground heat exchanger designed for use with heat recovery ventilation units. In cold winter seasons, the geothermal pre-conditioning prevents the ventilation unit's heat exchanger from freezing and becoming damaged. During hot summer periods, it cools incoming air, creating a comfortable indoor environment. The "GHT" geothermal pre-conditioning employs a geothermal heat collector to transfer heat from the ground to the air within the ventilation system.

Winter period

During extremely cold winters, the geothermal pre-conditioning heats incoming air to ensure the proper functioning of the ventilation unit. It utilizes ground heat at depths of 1.5 to 2.5 meters, where temperatures range from +5°C to +8°C.

Maximum heating capacity of up to 8 kW while consuming only 0.04 kW, for airflow up to 1000 m3/h.

Summer period

The brine defroster leverages ground coolness, with temperatures between +10°C and +14°C at depths of 1.5 to 2.5 meters, to cool incoming air.

Maximum cooling capacity of up to 8 kW while consuming only 0.04 kW, for airflow up to 1000 m3/h.
