EVHRA-D Autonomous unit with heat recuperator efficiency > 90%
Description
Active and passive heat recovery unit for the heating, cooling and air renewal of rooms, consisting of a one-piece structure including all components for correct operation: fans, cooling circuit with high efficiency compressors, air filtration sections and high efficiency counter-current heat recovery unit. The machine can work as a passive heat recovery unit and as an active thermodynamic heat recovery unit and it is particularly suitable for residential environments.
Characteristics
Complete unit capable of providing fresh air and integrating the heating or cooling requirements of the rooms served. The unit comes complete with all components required for its operation and it is ready for use. High efficiency counter-current cross-flow polypropylene heat exchanger. Low freezing temperatures and operation down to -25°C. Backward-curved fans with direct-coupled Brushless motor. The unit allows for the energy contained in the exhaust air to be recovered by means of a heat exchanger and cooling circuit, supplying it to the indoor environment. The heat recovery unit features two ePMl 70-80% filters on the supply and exhaust air with low pressure drops. Self-supporting frame with galvanised sheet metal sandwich panels, painted on the outside, with polystyrene insulation on the inside, internal cladding made of thick galvanised sheet metal. Cooling circuit made of brazed copper complete with high efficiency compressor, filter drier, finned coils, solenoid valves, electronic expansion valve, liquid receiver, pressure transducers and safety devices. The on-board electrical panel features a microprocessor and dedicated control thanks to which the speed of the fans is adjusted and the dirty filter warning is managed in a timed manner. In addition to this, a defrost procedure is automatically managed in extreme environmental conditions. Simplified touch interface for correct machine operation.
Use
Houses, surgeries and shops for air exchange with up to 90% reduction in energy waste.
Operating
In both winter and summer, the unit ventilates the rooms, recovering up to 90% of the energy through the sensible heat recovery unit. By means of the heat pump, the unit contributes to the room heating demand in winter and the cooling demand in summer.
