AIR HANDLING UNITS WITH HEAT RECOVERY

DescriptionThe air handling units are the fully featured ventila-tion units with heat recovery for air filtration, fresh air supply and stale air extract. During operation the extract air heat is transferred to the supply air stream by the highly efficient plate heat exchanger. The units are designed for energy efficient ventilation of cottages and flats and are compatible with round air ducts (Ø 150 mm).

Casing The casing is made of expanded polypropylene (EPP) with high heat and sound insulation characteristics.

FilterTwo built-in filters with filtration class G4 and F7 provide efficient supply air filtration. Extract air is cleaned by the integrated G4 filter.

MotorThe units are equipped with high-efficient EC motors with an external rotor and a centrifugal impeller with forward curved blades. These state-of-the-art motors offer the very best in energy efficiency today. EC mo-tors are characterised with high performance and opti-mum control across the entire speed range. In addition to that, the efficiency of the electronically commutat-ed motor reaches very impressive levels of up to 90 %.

Heat exchangerThe VUT 180 P5B EC units are equipped with a coun-ter-flow polystyrene heat exchanger. In the cold season the extract air heat is captured and transferred to the supply air stream which reduces the ventilation-gen-erated heat losses. This can lead to formation of con-densate that is collected in a special drain pan and dis-charged into the sewage system. In the warm season the ambient air heat is transferred to the exhaust air stream. This allows for a considerable reduction of the supply air temperature which, in turn, reduces the air conditioning load.

The VUE 180 P5B EC units are equipped with a counter-flow heat exchanger with an enthalpy mem-brane at the core. In the cold season the extract air heat and moisture are transferred to the supply air stream through the enthalpy membrane reducing the heat losses from ventilation. Consequently, it is the ambient air heat and moisture transferred to the exhaust air stream through the enthalpy membrane in the warm season. This allows for a considerable re-duction of the supply air temperature and humidity which, in turn, reduces the air conditioning load.

BypassThe units are equipped with a bypass for summer ventilation (cooling of the premise with a cool out-side air).

Control and automationThe VUT/VUE 180 P5B EC units are equipped with an A14 automation.The VUT/VUE 180 P5B EC A14 models have the A14 sensor control panel with LED indication.

Freeze protection

Supply fan stopping. The heat exchanger freeze protection operates as follows: in case of freezing danger determined by the temperature sensor the supply fan is turned off to let extract air warm up the heat exchanger. After freezing danger is no longer imminent, the unit reverts to the standard operation mode.

Installation The unit is designed for suspended ceiling, wall hori-zontal or vertical mounting using mounting brackets. While installing the unit, ensure convenient access for subsequent maintenance and repair.
