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, offices,
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, RECU – with plate heat exchanger, which may be replaced
with summer cassette, when recuperation is needless, air filters, an electric or water heater, fans and automa
-
tion 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 frost-
ing may appear. For this reason anti-frost protection function is foreseen in the controller of the Komfovent 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. Counter cross flow heat exchanger is the mostly sensitive for low out
-
side air temperatures, as the risk of frosting appears in the temperature range from 0 to -5 °C and below. Stan-
dard aluminium cross-flow plate heat exchanger has better features, as the risk of freezing appears only at
-10 °C. 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 temperatures of -30 °C if the humidity level of the air is appropriate.
