The dual flow heat exchanger recover most of the heat from the extracted air from the atmosphere in the winter period; in addition to ensure the air exchange within a building, the mechanical ventilation units combined with an air-air heat pump can heat all or part of the rooms. Thanks to the principle of the heat pump is possible to heat in the winter and cool in the summer period, reversing the operation cycle.
The units of dehumidification and air renewal with heat recovery are designed to be used in combination with radiant cooling installations, floor or ceiling, where normally occurs the problem of condensation: if the humidity level is too high, to avoid condensation I can not cool.
This machine is designed with an additional duct, for recirculation, used during dehumidification (recirculates clean air): all the air (mechanical ventilation + recirculation) is designed to dehumidify. The unit can also be installed at the service of existing plants.
