2. BRIEF DESCRIPTION OF THE UNIT
•
Casings of air handling units are made of galvanized steel sheets, which are powder painted. Mineral wool
is used for thermal insulation and sound attenuation. Unit cover panels are 45 mm thick.
• The air handling units are intended for ventilation of medium-sized spaces (eg. single family houses, offic
-
es, etc.), having operating ambient temperature and relative humidity. As standard, the unit is designed for
indoor placement. The operating temperature range for the unit is -30 °C ... 40 °C, outdoor air temperature.
•
The air handling unit is not to be used to transport solid particles, even not in areas where there is a risk
of explosive gases.
• REGO is equipped with a rotary heat exchanger, air filters, an electric or water heater, fans and automation
control system, to ensure safe and efficient operation of the unit.
•
Before you open the door, the unit must be switched off and the fans must have been given time to stop
(up to 3 minutes).
•
The unit contains heating elements that must not be touched when they are hot.
• We recommend to leave air handling unit in working mode (minimum 20 percent of power) during the first
operation year. Due to moisture in building constructions, condensation may occur inside and outside the
air handling unit. Continuous operation of the equipment will significantly reduce the risk of condensation.
•
To maintain a good indoor climate, comply with regulations and, to avoid condensation damage, the unit
must never be stopped apart from during service/maintenance or in connection with an accident.
•
If the unit is placed in spaces with high humidity, condensation might occur on the surface of the unit when
outdoor temperatures are very low.
•
Under conditions, when the outdoor air temperature is low and humidity is high, risk of heat exchanger
frosting may appear. For this reason anti-frost protection function is foreseen in the controller of the Kom-
fovent air handling units. Depending on the type of the recovery, different methods of anti-frost protection
are available: cold air by-passing, or / and supply air fan speed reducing. For extremely low outdoor air
temperature the duct mounted preheater is recommended. The lowest risk and the highest resistance to
cold outside air is a competitive feature of the rotary heat exchanger, as it is not freezing even at the tem-
peratures of -30 °C if the humidity level of the air is appropriate.
