The Vents VUT 300 G mini air handling unit is designed for ventilation of one to three rooms in residential or commercial premises. This model is capable of supplying fresh air with a nominal capacity of300 m3/h. The maximum consumption of the installation is only116 Wper hour, since the heating installation does not use a heater. Installation of the unit must be carried out in a closed room with a positive temperature. The ventilation unit is connected to125 mm air ducts. This model is mountedunder the ceiling or on the wall in a horizontal position.
Casing
The casing is made of aluminum-zinc steel, with internal heat and sound insulation 20 mm thick made of mineral wool.
Filter
To filter supply and exhaust air, the unit has two built-in filters with a cleaning degree of G4.
Fans
The Vents VUT 300 G mini unit is equipped with supply and exhaust centrifugal fans with backward-curved blades and a built-in protection thermostat with automatic restart. Electric motors and impellers are dynamically balanced in two planes.
Recuperator
The plate recuperator is made of aluminum plates. A “summer” liner is provided for operating the unit without recuperation. Under the recuperator block there is a tray for collecting and discharging condensate. The air handling unit is equipped with a built-in system for protecting the recuperator from freezing.
During the operation of the recuperator in the cold season, heat is transferred from warm exhaust air to cold supply air. In this case, condensation may form in the recuperator during the cooling of the exhaust air, and when the temperature of the supply air entering the recuperator on the other side is on average below -5°C, the condensate in the exhaust ducts may freeze.
To avoid freezing of the recuperator, electronic anti-freeze protection is used. Its essence is that the temperature sensor turns off the supply fan. Warm exhaust air warms up the recuperator. Then the supply fan turns on and the entire installation operates as usual.
Control
The installation is turned on and its performance is controlled using a thyristor engine speed controller (RS-1-400), which allows you to smoothly change the fan speed in the range of 0–100%.
Installation
The air handling unit is mounted on the floor, suspended from the ceiling using a mounting angle 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 folding side panel.
