Application
1. Compact air supply and exhaust ventilation unit DHRV is a simple and effective energy-saving solution ventilation of apartments, cottages, single-family houses, workshops and trade premises.
2. The unit is a fully-featured ventilation unit that provides air cleaning, fresh air supply to the premise and removal of extract air from the premise.
3. Extract air thermal energy is transferred to the cross-flow heat exchanger and is used to warm up the supply air flow.
4. Built-in heat exchanger prevents heat losses and saves operating costs for heating in winter and air conditioning in summer.
Design
1. The casing is made of corrosion-resistant alumozink and sound-insulated with 15 mm cellular polyethylene layer.
2. For easy mounting the casing is fitted with mounting brackets.
3. The detachable panel is swivel connected to the unit to provide fast and easy access to the casing internal components for servicing and maintenance.
4. The unit is equipped with two backdraft dampers, one in the supply and the other in the exhaust air duct.
Fans
1. The unit is equipped with reliable supply and exhaust fans with forward curved blades that are powered by motors with low energy demand.
2. The motor has maintenance-free ball bearings that ensure long service life about 40 000 hrs and are greased for the operation period.
Filters
1. and extract air flows are purified through two filters with filtering class G4.
2. The filters prevent dirt and dust ingress into the room and protect the unit components against contaminations.
Heat Exchanger Vents
1. Cross-flow enthalpy heat exchanger with heat recovery efficiency from 64 % up to 72 % enables not only heat but humidity recovery and provides indoor humidity balance.
2. In summer season the heat exchanger serves for intake air cooling down and drying and in winter season for warming up and moisturizing. Water vapour is extracted from wet extract air and is absorbed by the heat exchanging plates.
Control
1. Air flow (speed) is regulated with A3 (P3-1-300) speed switch.
2. Low speed – 55 m³/h, 24 dBA
3. Medium speed – 74 m³/h, 32 dBA
4. Maximum speed – 100 m³/h, 41 dBA
5. The external speed switch is comfortable to use at any place.
Heat Exchanger Protection
For freeze protection at low temperatures the unit is equipped with a thermostat inside the casing that switches the supply fan off in case of freezing danger to let extract air warm up the heat exchanger.
Mounting
Due to the compact casing height the unit is designed for horizontal indoor installation behind suspended ceilings and connection to Ø 125 mm round air ducts.
