Page 5: Principles 1. 1 Heat Yield
Principles 1.1 Heat yield Thermal flux Ground Primary Cooling Heating circuit circuit system well (brine) circuit The ground as a heat source Water as a heat source (well circuit) Flat-plate collectors or geothermal probes extract heat from the The water circulating in the well circuit transfers the heat to the primary ground.
Page 6: Operating Modes
Drilling contractors certified according to the DVGW Code of Practice Under standard hydro geological conditions, an average extraction W 120 should be engaged to carry out the drilling work. Viessmann capacity of 50 W/m probe length can be assumed for geothermal probe recommends the work to be carried out by the geothermal energy systems (according to VDI 4640).

Principles (cont.) Screed drying In water/water heat pumps, it is generally sufficient to increase the Top covers (such as tiles, parquet etc.) permit only minor residual pump rate to cover the higher heat demand. moisture in the screed prior to their application. Screed drying also requires a higher heat demand.
Page 9: Noise Development
Principles (cont.) Natural cooling is possible with the following systems: Temperature in °C ■ Underfloor heating systems on the surface of the ground ■ Fan convectors ■ Chilled ceilings 1 May 1 Nov. ■ Concrete core tempering 1 Feb. 1 Aug. The ambient air can only be dehumidified in conjunction with the nat- ural cooling function if fan convectors are connected (condensate drain required).
Page 10: Sound Power Level And Sound Pressure Level
Principles (cont.) Structure-borne noise, liquid-borne noise Mechanical vibrations present in equipment, such as machine and building components as well as in liquids, are transmitted through them and radiated out by them at different points as airborne noise. Airborne noise Sound sources (equipment in which vibrations are present) create mechanical vibrations in the air that propagate in wave form and are audible to the human ear at different levels.
Page 11: Propagation Of Sound In Buildings
Principles (cont.) Propagation of sound in buildings In buildings, sound generally results from the transmission of structure- borne noise via the floors and walls. The sound emissions from light wells frequently not only lead to disturbances around the building but also inside the owner's property.
