DESIGN AND OPERATING PRINCIPLE

The unit operation is as follows:
Warm extract air from the room flows into the unit and is cleaned in the extract filters. Then the air is moved through the heat exchanger and is exhausted outside through the air ducts with the extract fan. Cold fresh air from outside flows into the unit, where it is cleaned with the supply filters. Then the air flows through the heat exchanger and is moved to the room with the supply fan. Supply air is heated in the heat exchanger by transferring the heat energy of warm and humid extract air to the cold fresh air. The air flows are fully separated while flowing through the heat exchanger. Heat recovery minimizes heat losses, which reduces the cost of space heating in the cold season. The unit is a frame structure made of rigidly fixed steel panels. The panels are made of painted steel sheets and a galvanized steel sheets with a layer of mineral wool between for heat- and sound-insulation.
The service door enables access for maintenance and service operations.
The power cables and grounding conductors must be routed through the cable glands to the terminal block located on the top casing panel. The wiring diagram for wiring of the air handling unit is shown on the inner side of the terminal box lid. The unit design enables installation of a bypass duct with a bypass damper to route the intake air stream without contacting the heat exchanger. The unit has three automatic heat exchanger freeze protection modes, depending on the unit model.
Units without heater: the supply fan turns off in case of a freezing danger.
Units with a reheater and no preheater: the bypass system is activated in case of a freezing danger.
Units with a preheater: the preheating is turned on in case of a freezing danger*.

• danger of freezing appears when the exhaust air temperature downstream of the heat exchanger is lower than +5 °C and intake air temperature upstream of the heat exchanger is lower than -3 °C. After increase of these temperatures the unit reverts to the previous operation mode.
  The supply and extract air temperature difference during heat recovery may lead to condensate formation in the units with a polystyrene heat exchanger. The condensate is collected in the drain pan and is removed outside to the exhaust air duct through the drain hose. No condensate is generated in the units with an enthalpy heat exchanger as the air moisture is transferred from one air stream to the other via the membrane.
  The unit has options for connection of a humidity sensor, CO2 sensor or VOC (air quality) sensor for automatic keeping of set humidity level, CO2 or VOC concentration in the room.

UNIT OPERATING PRINCIPLE

UNIT DESIGN

Additional equipment (is not included in the delivery set, can be ordered separately)

• Humidity sensor. The unit with the installed humidity sensor maintains a set indoor humidity point. As the extract air humidity rises above the set point, the system automatically switches to the maximum speed. As the humidity drops down below the set point the unit returns to the previous mode
• CO2 sensor. Measures the level of concentration of carbon dioxide in the room and generates a signal that controls the performance of the fan. Air capacity control based on CO2 concentration is an efficient energy saving solution.
• VOC sensor. Qualitative assessment of air saturation with contaminants (cigarette smoke, exhaled air, solvent and detergent vapours). The sensor sensitivity can be adjusted with regards to the expected maximum level of air pollution. Enables on-demand ventilation which results in considerable energy savings as air is exchanged only upon reaching the preset level of pollution.

MOUNTING AND SET-UP

READ THE USER’S MANUAL BEFORE INSTALLING THE UNIT.

Sufficient service access to the unit for maintenance or repair operations must be provided.

The recommended minimum distances from the unit to the walls are shown below.
