EVHRA Autonomous unit with heat recuperator up to 5000 m³/h

Description

Active recovery unit for heating, cooling and room air renewal.
The unit is composed of a monobloc including all components for correct operation: fans, refrigeration circuit with high efficiency compressors, air filtration sections and cross-flow heat recovery unit.

Use

EVHRA works as a passive recuperator and as an active thermodynamic recuperator and is particularly suitable for residential, commercial or collective residential buildings, it has plug-and-play for a quick and simplified installation.

Unit components

REFRIGERANT CIRCUIT:
- high efficiency rotary or scroll compressor;
- copper tube batteries with aluminium fins;
- 4-way reversing valve;
- electronic expansion valve;
- dehydrator filter;
- pressure transducers;
- liquid receiver;
- high pressure pressure and safety devices.

AERAULIC CIRCUIT:
- cross-flow aluminium heat recovery unit;
- double suction centrifugal fans;
- ePM1 70-80% filters.

ELECTRICAL CIRCUIT:
- general actuator;
- protection fuses;
- contactors and relays;
- microprocessor.

Characteristics

Panels made by double sandwich panel 38 mm thickness, with externally white painted finish and Aluzinc inside the unit.
Perimeter structure with aluminium profiles, with seals and no air leakage. The insulation of the panels is made with high performance insulation which allows low noise and reduced transmittances during unit operation.
Coss-flow aluminium heat exchanger has an efficiency of 50-60%. Summer and winter operation.
Double suction centrifugal fans with directly coupled motor compliant with Erp regulations.
The thermodynamic recovery allows, thanks to its refrigeration circuit, to supply energy to the environment in a greater quantity than that subtracted from ventilation.
Upstream of the recovery unit there are two filters with easily removable ePM1 70-80% filtration class.
Refrigerant circuit made of brazed copper complete with: high efficiency compressor, dehydrating filter, finned batteries, solenoid valves, electronic expansion valve, receiver
liquid, pressure transducers and safety devices.
On-board electrical panel with microprocessor and dedicated regulation. Fan management, visualization of internal temperature probes, temporized dirty filters management.
Defrost algorithm management
optimized for operation with low internal temperatures.
Wide graphical interface with configuration menu and multi-lingual user menu.
Predisposition for MODBUS RTU RS 485 communication with the most varied home automation systems.
