Three Technological Solutions

This system features a pure refrigerating circuit in which the heat-absorbing loops are the system's evaporator and the floor coils are the condenser: evaporation and condensation occur gradually, thus maximising efficiency. The generator housing, which can be installed in the garage, cellar, or other utility area, comprises a compressor and the expansion valve. Several compressors can be installed, thus allowing for varying temperatures in different indoor areas. This is the most efficient solution since it requires a minimum outdoor surface.

In addition to the compressor and the expansion valve, the generator housing includes two exchangers where the evaporation and condensation processes take place, thereby releasing the energy to heat the water. This technology is also compatible with radiator systems already in place (maximum temperature 45°C). This system requires a larger outdoor surface area than the direct condensation and evaporation system. It is possible, however, in certain sites to sink geothermal probes deep into the soil, thereby reducing the surface area necessary.

This technology is a combination of the first two systems: it features a refrigerant fluid in the outdoor loops and a hydraulic circuit for the floor or radiators. Like in the direct condensation and evaporation system, the evaporation process occurs directly in the external loops. The generator housing comprises a condenser that releases the energy used to heat the water, which then flows through the floor coils or the radiator system. This technology, like the dual water heat exchanger system, offers the option of using existing radiators
