TERRApump - Ground / Water heat pumps

 

Heat source: the ground

 

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).

 

Advantages of our ground/water heat pumps:

 

- 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.

 


 

AQUApump - Water / Water heat pumps

 

Hea source: groundwater

 

Ground water is a very suitable energy source for the exploitation with a heat pump. Its main advantage is a relatively constant temperature level (between +7 and +12°C). To be able to exploit ground water we need to drill two boreholes into the ground – one for the extraction of water and one to return the water into the ground. A submersible pump into the extraction well pushes the water through the heat pump, which then extracts thermal energy from the water, and returns it (cooled by a few °C – from 2 to 4) back into the ground through the second borehole, which is about 15 to 20 m away. The amount of water in the borehole must be sufficient for continuous operation even at the highest heat necessities. To extract ground water we need a water permit and a chemical analysis of the water before any work is done. Due to a relatively high
temperature, the ground water is an ideal heat source with the highest energy efficiency (based on the annual average), since it reaches a very high COP.

 

Advantages of our water/water heat pumps:

 

- Integrated electronic control for monitoring the device and controlling the heating system.
- 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.
- Elastic mounting of the entire cooling system to the housing (dual anti-vibration mounting of the compressor) decreases the system’s oscillation and noise.
- Incredibly silent appliances with a sound-insulated housing and a twice dampened compressor.
- Compact dimensions of the heat pump.
- Environmentally friendly R 407 C refrigerant.

 


 

R - active cooling version

 

Only active cooling offers genuine benefits. R version heat pumps offer active cooling function. This means that in summer the internal cooling circuit is reversed and actively pumps heat out of the house into the heat sink. So your house stays cool even over long hot periods.

 

HE - high temperature version

 

High-temperature heat pumps have a special type of a compressor and refrigeration system which enables the heating of output water up to 65 °C. They are mainly convenient for alteration of existing buildings with radiators. In new buildings, we always choose systems which require lower temperatures of the heating water for cost saving purposes.
