Description

DESCRIPTION
The VUT/VUE WH EC air handling units with a water heater are the fully-featured ventilation units that ensure air filtration, fresh air supply and stale air extract. During the operation process the extract air heat is transferred to the supply air through the plate heat exchanger. The units are used in ventilation and air conditioning systems installed in various premises that require reasonable energy saving solutions and controllable ventilation systems.	EC motors reduce energy demand by 1.5-3 times and ensure high performance and low noise operation. Designed for connection to ø150, 160 and 200 mm round air ducts.
MODIFICATIONS
VUT WH EC – models with water (glycol) heaters, fans with EC motors, counter-flow duct hexagonal heat exchanger made of polystyrene.	VUE WH EC – models with water (glycol) heaters, fans with EC motors, counter-flow duct hexagonal heat exchanger with an enthalpy membrane at the core.
CASING
Made of aluzinc steel, internally filled with a 25 mm mineral wool heat- and sound-insulating layer.
FILTER
Two incorporated filters (G4 panel filter for extract air ventilation and F7 filter for supply air ventilation) are supplied with the unit.
FANS
The units feature efficient electronically commutated (EC) direct current motors with external rotor and centrifugal double-intake impellers with forward curved blades. These state-of-the-art motors offer the very best in energy efficiency today.	EC motors are characterised with high performance and optimum control across the entire speed range. In addition to that the efficiency of the electronically commutated motor reaches very impressive levels of up to 90 %.
HEAT EXCHANGER	The VUE WH EC units are equipped with a counter-flow heat exchanger with an enthalpy membrane 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 reduction of the supply air temperature and humidity which, in turn, reduces the air conditioning load.
The units are equipped with high efficient heat exchangers with heat recovery up to 98 %. The VUT WH EC models are equipped with counter-flow heat exchangers made of polystyrene. The unit is equipped with a drain pan for condensate drainage and removal.
HEATER
The VUT/VUE WH water heater at outlet from the heat exchanger is designed for warming up of supply air up to the set level if heat recovery is not enough to attain the set supply air temperature.	The water heaters are designed for maximum operating pressure 1.0 MPa (10 bar) and maximum heat medium operating temperature +95 °C.
CONTROL AND AUTOMATION
The unit incorporates an integrated automation and control system with a multifunctional control panel with a graphical display. The standard delivery set includes a 10 m cable for connection to the control panel. The freezing protection function is performed by means of the bypass and the heater. In case of a freezing danger according to the temperature sensor readings the bypass damper is opened to let supply air flow through the bypass duct and not come in contact with the heat exchanger.	The heater warms up supply air up to the required temperature and meanwhile the heat exchanger is heated by the warm extract air. After the heat exchanger defrosting, the bypass damper closes the bypass duct and the air handling unit reverts to the standard operation mode.
VUT/VUE WH EC CONTROL AND PROTECTION FUNCTIONS
Via control panel: Turning air handling unit on/off, room temperature indication, low-medium-high speed selection. Supply and exhaust fan speed can be adjusted from 0 to 100 % for each of 3 speeds during the system set-up. Maintaining supply air temperature set from the control panel by controlling the circulation pump and actuating the heat medium regulating valve. The air temperature sensor downstream of the heater and the return water temperature sensor are used for freezing protection of the heater.	Safe start-up/shutdown of the fans, warming up of the water heater before start-up; maintaining the set return heat medium temperature when the fan is off. Actuating the external air dampers with a return spring. System shutdown on signal from fire fighting system. Smooth bypass damper control in the freeze protection mode to prevent the heat exchanger freezing.
INSTALLATION
The units are designed for suspended installation under the ceiling. They can also be mounted on a wall in a vertical or horizontal position.	The access for unit and filter maintenance is available from the service panel.
ACCESSORIES
For attenuation of sound generated by the fans it is recommended to install the duct silencer SR from inside upstream of the unit. For vibration absorbing it is recommended to install the flexible anti-vibration connectors VVG on both sides of the unit. The VUT WH units are recommended to be equipped with automatic air dampers for the water heater freezing protection when the fans are off.	The USWK mixing units are recommended for smooth supply air temperature regulation in the units equipped with water heaters. The mixing unit USWK with a three-way heat medium regulating valve and circulation pump provides smooth heating capacity regulation and minimizes the water heater freezing danger.
