Ground-source heat pumps exploit thermal energy stored in the rocks or soil. An enormous amount of solar energy that is stored in the soil can easily be used for space or tap water heating. The amount of solar energy that can be extracted from the soil depends on the composition of the soil, on the heat pump capacity, and the manner of the source exploitation (horizontal collector or vertical probe).
The energy is extracted by means water (+ antifreeze agent) which circulates in a closed piping system laid at a depth of 110 – 130 cm (horizontal collector); in case of a vertical probe, the tubular probes are placed into boreholes at a depth of 60 – 140 m. The circulating water transfers heat to the heat pump, which transforms this heat to a higher temperature level (to 55°C) by the help of added electrical energy; the returned water is cooled by approximately 4°C).
- Integrated electronic regulation to control the device and to operate the system.
- Incredibly silent appliances with a sound-insulated housing and a twice dampened compressor.
- Elastic mounting of the entire cooling system to the housing (dual anti-vibration mounting of the compressor) decreases the system’s oscillation and noise.
- Compact dimensions of the heat pump.
- A highly efficient and silent Copeland scroll ZH compressor purpose developed for heath pumps.
- An optimised plate evaporator and a condenser made of stainless steel.
- A thermostatic expansion valve.
- A simple and quickly removable cover of the housing enables quick access to the system’s elements.
- Environmentally friendly R 407 C refrigerant.
