The air supply and exhaust unit Vents VUT 400 EG EC is designed for supply and exhaust ventilation of residential or commercial premises. The unit uses heat recovery and an4 kWelectric heater to additionally heat the air, which is used at low air temperatures. The nominal capacity of this model is400 m3/hwith a maximum head of 700 Pa. The fans of the unit use EC motors, which makes it possible to connect a fairly long network of air ducts.
The ventilation unit is equipped with an automatic control system and is completely ready for operation. The diameter of the air ducts used is 200 mm, installation of the unit must be carried out in a closed room with a positive temperature (attic, heating station, corridor, dressing room, glazed loggia, etc.)
Housing
The body 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
Uses highly efficient electronically commutated (EC) external rotor DC motors equipped with a double-inlet 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 400 EG 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 EG 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 EG EC
- turning the unit on and off,
- the ability to use the control panel to set the desired supply air temperature and maintain the set one,
- the ability to use the control panel to regulate the fan rotation speed and, accordingly, change the performance of the installation,
- the ability to control the electric drives of the air dampers,
- when turning the installation on and off, the settings are processed necessary algorithms,
- operation of the installation on a weekly timer,
- active protection against overheating of the heater heating elements,
- exclusion of the operation of the electric heater without turning on the fan,
- two thermostats are installed to protect the electric heater from overheating,
- the automation system is protected from short circuits by a circuit breaker,
- the degree of filter clogging is controlled.
Supply supply - the exhaust unit is equipped with a remote control, which provides:
- turning on/off the ventilation unit,
- setting the required air flow,
- setting the required supply air temperature air,
- 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 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.
