Electrical panel on the unit with microprocessor and dedicated control. Cooling circuit with high efficiency compressor.
Command electronics
Version K: Electrical panel on board unit with microprocessor and dedicated regulation. Fan management, display of internal machine temperature probes, timed dirty filter management, recirculation and renewal air management.
Possibility to control the unit with these three solutions:
- 1: Management through external commands and 0-10vdc signal to control air flow from minimum to maximum;
- 2: Management through remote panel with integrated T / H sensor;
- 3: MODBUS RTU RS 485 communication.
Use
Versions
Version D: version for dehumidification with neutral air (isothermal).
Unit for the renewal of the ambient air with the external one through a high efficiency recuperator, the air flow is increased by partially recirculating the ambient air thus allowing the operation of the refrigeration circuit, obtaining during the summer period (compressor active) dehumidified air .
Equipped with a post-cooling / heating hydronic battery which, if supplied, provides a supplement to the cooling / heating capacity of the radiant air-conditioning system (the connection to the heating / cooling system is optional and does not affect air dehumidification).
Version DC: version for dehumidification and integration in cooling / heating.
Unit for the renewal of the ambient air with the external one through a high efficiency recuperator, the air flow is increased by partially recirculating the ambient air thus allowing to dehumidify the air and to provide an integration of the cooling / thermal power radiant air conditioning system.
During the summer (active compressor) the unit can work in 2 modes:
Renewal + Dehumidification: The unit condenses partially in air and partially in water through the plate condenser, obtaining dehumidified air;
Renewal + Dehumidification + Cooling integration: The unit completely condenses in water, thus obtaining dehumidified and cooled air. During the winter period (compressor off) the hydronic battery is supplied with hot water from the heating system and behaves like a thermo-ventilator with recuperator.
Operation Only with Ventilation
The EVHRD unit will cater for mechanical ventilation with high efficiency heat recovery. It will be possible to select the fan speeds in order to obtain the desired flow rate to meet the air renewal requirements.
The selectable flow rates are:
On size EVHRD 30-15 from 0 to 150 m³/h
On size EVHRD 50-25 from 0 to 250 m³/h
Ventilation, Dehumidification and Integration Operation
The EVHRD unit will continue to satisfy the mechanical ventilation with high efficiency heat recovery but will increase the air flow rate, recirculating from a dedicated ambient air duct to increase the air volume on the integration part.
The integration part can consist of a version
with dehumidification (Version D), from a version with dehumidification and integration (Version DC) and hydronic supplementary batteries.
The D version, finds its most common application, in radiant systems where there is the need of only dehumidification in the summer. During operation, the unit, through humidity and temperature probes, activates the refrigerant circuit composed of the compressor, the air evaporation coil and the air condenser, thus performing dehumidification. It is possible to supply the hydronic post battery with the radiant system water (the lack of battery power does not compromise the operation of the refrigeration circuit) it is possible to integrate it with the summer cooling and the winter heating.
The DC version, finds its most common application, in radiant systems where there is the need for dehumidification and the integration of cooling in the summer. During operation, the unit, through humidity and temperature probes, activates the refrigerant circuit composed of the compressor, the air evaporation coil and the air and water condenser supplied by the radiant system, thus achieving air dehumidification and integration. cooling.
In winter, it is still possible to use the unit to integrate the radiant heating by feeding the hot water hydronic battery, obtaining a rapid thermal contribution to the environment.
