APPLICATION

Air handling units for efficient supply and exhaust ventilation in flats, houses, cottages and other buildings.For arranging of controlled energy saving ventilation systems.Heat recovery minimises ventilation heat losses.Controllable air exchange for creating the best suitable indoor microclimate.Compatible with round Ø160, 200 and 250 mm air ducts.

DESIGN

The casing is made of double-skinned aluzinc panels, internally filled with 25 mm mineral wool layer for heat and sound insulation.Casing has fixing brackets with vibration absorbing connectors for easy installation.The hinged casing panel ensures easy access to the internals for cleaning and other maintenance operations.The spigots for connection to the air ducts are located at the side of the unit and are rubber sealed for airtight connection to the air ducts.The bypass damper is opened automatically in summer time to cool down a room with cool outside air. For the model with a heater the bypass damper is also used for the heat exchanger freezing protection.

FANS

High-efficient external rotor EC motors and centrifugal impellers are used for air supply and exhaust.The forward curved blades in KOMFORT EC LB300/LB400/LBE300/LBE400 S11 provide permanent air flow.The KOMFORT EC LB600/LBE600 S11 model has impellers with backward curved blades.EC motors have the best power consumption to air capacity ratio and meet the latest demands concerning energy saving and highefficient ventilation.EC motors are featured with high performance, low noise level and totally controllable speed range.Dynamically balanced impellers.

AIR HEATER

The KOMFORT EC LBE S11 model is equipped with an electric heater for operation during cold seasons at low outside temperature.The integrated electric heater is activated to warm up supply air flow if set indoor air temperature may not be reached by means of heat recovery only.Smooth heat output control ensures automatic supply air temperature maintaining.Two integrated overheat protection thermostats, one actuated at +60 °C with automatic restart and the other one actuated at +90 °C with manual restart.

AIR FILTRATION

The built-in G4 pocket supply filter and G4 cassette extract filter provide efficient air filtration. Optionally, an F7 supply filter may be used.

HEAT RECOVERY

The unit is equipped with a counter-flow polystyrene heat exchanger with a large surface area and high heat recovery efficiency.Heat recovery is based on utilization of heat energy contained in the extract air stream for heating up of supply air stream. Extract air transfers most of its heat to the intake air flow. Heat recovery reduces heat energy losses in cold seasons.In summer the heat exchanger performs reverse and intake air is cooled in the heat exchanger by the cool extract air. This contributes to better performance of the air conditioner in ventilated premises.The drain pan under the heat exchanger block is used for condensate collection. The drain pan is fitted with a drain pipe for condensate removal.The electronic freeze protection system is used to prevent the heat exchanger freezing in the cold season:

  • KOMFORT EC LBE S11: the bypass damper is opened according to the temperature sensor feedback to let supply air flow pass along the bypass air duct. Synchronously, the heat exchanger surface is warmed up with warm extract air flow. After a freezing danger is over the bypass damper is closed and the unit reverts to the normal operation mode.
  • KOMFORT EC LB S11: in case of a freezing danger registered by the outdoor temperature sensor the supply fan is turned off to let the heat exchanger surface get warmed up with warm extract air flow. After a freezing danger is over the supply fan is turned on and the unit reverts to the standard operation mode.

CONTROL AND AUTOMATION

The units incorporate an integrated control system with a wallmounted control panel and sensor display.The standard delivery set includes a 10 m cable for connection of the unit and the control panel.Automation functions:

  • Activating/deactivating the unit.
  • Setting low, medium and high speeds for the supply and extract fan as well as air flow control. Each speed is individually adjusted during set-up.
  • Automatic heater activation/deactivation and smooth heat output control. Heater overheating protection. Cooling of the heater at the end of the heating cycle for KOMFORT EC LBE S11.
  • Opening/closing the bypass damper for summer ventilation.
  • Setting and maintaining room or duct air temperature.
  • Timer activation/deactivation and set-up.
  • Setting day- and week-scheduled operation of the unit.
  • Operation control on feedback from FS1 duct humidity sensor (to be ordered separately) or from the humidity sensor in the control panel.
  • Filter clogging control.
  • System shutdown on signal from a fire alarm panel.
  • Controlling supply and exhaust air dampers (available separately).
  • Cooler control (available separately).

MOUNTING

The unit is suitable for floor, ceiling or wall mounting using fixing brackets.The correct mounted unit must provide free condensate collection and drainage as well as good access for servicing and filter replacement.The service access is on the side of the removable service side panel, leftwards along supply air flow.
