The Vents VUT 600 VG EC unit is designed to provide supply and exhaust ventilation for residential or commercial premises. To heat the outside air during the cold season, the installation uses a heat recuperator and additional reheating with a water heater. The heater requires a hot water supply from the boiler. The nominal capacity of this unit is 550 m3/h, the diameter of the connected air ducts is 200 mm.
The unit uses economical fans with EC motors, which have high pressure and low noise level. Installation of such an installation must be done indoors.
Casing
The casing is made of aluminum-zinc steel with internal heat and sound insulation made of 25 mm thick mineral wool.
Filter
To filter supply and exhaust air, the unit has two built-in filters with a cleaning degree of G4 (exhaust) and F7 (supply).
Fans
Highly efficient electronically commutated (EC) external rotor DC motors are used, equipped with a double-suction impeller with forward-curved blades. Such motors are by far the most advanced solution in the field of energy saving. EC motors are characterized by high performance and optimal control over the entire speed range. The undoubted advantage of an electronically commutated motor is its high efficiency (up to 90%).
Recuperator
Vents VUT 600 VG EC units use highly efficient recuperators (about 95%). In models VUT EG EC and VUT VG EC, counterflow recuperators are made of polystyrene. Under the recuperator block there is a tray for collecting and discharging condensate.
Heater
To operate the air handling unit at low outside temperatures, electric (for VUT EH EC models) or water (for VUT VG) heaters are installed. If using heat recovery it is not possible to achieve the set value of the supply air temperature, the heater automatically turns on and heats the air entering the room.
Control and automation
The installation is equipped with a built-in automation system and a multifunctional control panel with a graphic indicator. The standard installation kit includes a 10 m long wire for connecting to the remote control. To prevent the recuperator from freezing, electronic anti-freeze protection is used using a bypass and a heater. Its essence is that, based on the temperature sensor, the bypass damper opens and all the supply air passes past the recuperator through the bypass channel. During the defrosting period of the recuperator, the supply air is heated to the required temperature in the heater. During defrosting, warm exhaust air warms up the recuperator. Then the damper closes the bypass, the heater turns off, the supply air again passes and is heated through the recuperator, and the entire installation operates as usual.
Control and protection functions of VUT VG (EC)
- turning on and off the installation,
- control of the supply air temperature by influencing the three-way valve drive, regulating the supply of coolant to the liquid heater,
- protecting the liquid heater from freezing (using the air temperature sensor after the heater and the return coolant temperature sensor,
- controlling the electric drive of the recuperator bypass valve,
- control and monitoring of the operation of an external circulation pump installed on the coolant supply line to the liquid heater,
- protection of the heat exchanger from icing,
- control and monitoring of the operation of the supply and exhaust fans,
- control of filter contamination (based on the number of operating hours),
- control of electric drives of external air valves (supply and exhaust).
The air handling unit is equipped with remote control panel, which provides:
- turning on/off the ventilation unit,
- setting the required air flow,
- setting the required supply air temperature,
- display of room temperature.
Installation
The air handling unit is mounted on the floor, suspended from the ceiling using a mounting bracket with a vibration insert, or mounted on the wall with using brackets. The installation can be placed both in auxiliary rooms and in the main ones (behind a suspended ceiling, in a niche or in an open way). It can only be installed in such a position as to ensure collection and drainage of condensate. Access for service and filter cleaning is from the side panels.
