1.2. Unit Types and Sizes
An air-handling unit is a device designed to ensure good ventilation in the premises. An air- handling unit removes indoor
air containing carbon dioxide, various allergens or dust, while replacing it with filtered fresh air from outside. As the outside
air is usually colder or warmer than the air within the premises, an integrated recuperator (heat exchanger) collects thermal
energy from the indoor air and transfers the majority of it to the supply air. When a recuperator is not capable of reaching a
desired temperature, additional heaters or coolers may be activated.
Heat exchangers and heaters (or coolers) are designed to compensate for heat/cool losses during
ventilation, therefore, we do not recommend using this unit as the main heating/cooling source.
The unit may fail to reach a user-defined supply air temperature when the actual temperature in the
premises differs significantly from the temperature set point, since this will lead to inefficient opera-
tion of a heat exchanger.
RHP
– air handling units with a rotary heat exchanger and an integrated heat pump. Rotating wheel (rotor) of a rotary
heat exchanger collects heat or cold from the indoor air and transfers it to the fresh supply air. Recovered heat/cold capacity
is changed by adjusting the rotor speed. When heat recovery is not required, the wheel stops. If a heat exchanger alone is
not capable of reaching a desired temperature, an integrated heat pump is activated. If heating/cooling capacity is still too
low, additional heaters or coolers may be activated.

Maximum air volume may be limited according to the order, for example, if lower power fans are used or higher air vo-
lume is not required by the project requirements. For exact maximum air volume see the technical data print-out of the
specific unit.
