Fresh air terminal units with heat pump active thermodynamic recovery and opposing flow passive recovery.
Construction features
• Recovery unit:
– First stage of heat recovery of static air-air type, sensitive or enthalpy, with opposing flows in very high efficiency polypropylene.
– Second stage of heat pump active thermodynamic heat recovery (with R410A gas) consisting of high efficiency BLDC horizontal rotary hermetic compressor, evaporating and condensing coils with copper pipes and aluminium fins, electronic expansion valve and safety devices, 4-way valve for cycle inversion and dryer filter.
• Fans: UTR double-intake centrifugal fans with constant flow EC motor for fresh and expelled air; UTRR: EC radial fans with constant flow for fresh and expelled air, centrifugal fans with double-intake, with EC motor, for recirculation air.
• Filtering section: 80% ePM1 filters with low pressure drop air side renewal and ambient inlet, both removable at the bottom; 70% coarse filters on the recirculation side removable at the bottom, for UTRR.
• Self-supporting structure, double side sandwich panelling, internally galvanised sheet steel and externally painted (RAL 9003), with high density polystyrene insulation (20 mm thick). Circular inlets (Ø 200 mm) with sealing gasket for connection to the air ducts; lower condensate collection tank with double drain.
• Electrical adjustment and power panel integrated on the unit; electronic microprocessor control for fan speed management, temperature display, timed dirty filter management, air quality sensor management with flow modulation, humidity sensor management for dehumidification mode, summer/winter changeover and defrosting cycles.
