Lessons learned 

  • Specialized heat pump Systems allows to use this technology in all comfort functions, from space heating and cooling to ventilation and energy recovery
  • Small flats can benefit from innovative solutions such as the multi-function packaged air-to-air heat pump. Complete with DHW production, it fits in both architectural and historical buildings, as it does not need any outdoor unit

Description of the technical concept

In terms of heating and cooling, all larger apartments are equipped with a full inverter air-to-water heat pump, split-type with recessed indoor unit. This provides heating and cooling to the underfloor system, with additional domestic hot water.

The ventilation system for air renewal and purification, humidity control and thermodynamic energy recovery eliminates more than 95% of fumes, dust, viruses, bacteria and polluting particles.

Smaller flats each have a compact multi-functional air-to-air heat pump providing heating, cooling and domestic hot water, as well as renewing and purifying the air. The units use mechanical ventilation ducts for heating and air conditioning, to simplify the system. Electronic filters purify the outside air with an efficiency greater than 99.9%. Active thermodynamic recovery saves and amplifies the energy contained in the exhaust air. No outdoor units are needed.

The system can be managed remotely to customize the settings.
