The Carrier 42BJ ICM (Individual Comfort Module) is a compact air conditioning system available in 3 sizes, designed for conditioning rooms measuring 25 to 50 m².
  • All-in-one offer: minimal installation costs thanks to factory-tested and fitted-options
  • Easy integration into a centralized zone
  • Very low sound level
  • Available static pressure: 100 to 350 Pa

carrier-IdroFan

General description

  • Connected by flexible sound-absorbing ducts (heat insulated air discharge duct) to one or more plenums
  • Can be fitted in suspended ceilings or raised floors, ideally in corridors, where they are connected to hot water, chilled water and fresh air circuits
  • Designed to be ultra quiet

Comfort

  • Equipped with a Carrier digital control, providing each occupant with a remote user interface located on their desktop or wall and enabling individual selection of room temperature, forced air function, occupied/unoccupied mode
  • Aquasmart Evolution is used to control and optimize each module to obtain the best balance between energy savings and individual comfort

Indoor air quality

  • In this application, each individual comfort module (ICM LEC) is equipped with a fresh air intake control and high-efficiency filtration to successfully protect against any type of pollutant
  • High efficiency filtration : type F5 or F6
  • Fresh air flow modulation system to control the air flow diffused in a room

Three objectives 

  • Adapt the ventilation flow rate to the actual occupancy of the rooms
  • Maintain excellent indoor air quality to ensure the comfort and health of occupants, in accordance with the labour code
  • Control energy costs relating to air change in rooms to avoid "over-ventilating" the building and to minimize operating costs, particularly when the building is unoccupied

Operating principle 

  • A CO2 sensor measures the concentration of the room
  • The sensor sends a signal to the Carrier digital controller which, in turn, sends a signal to actuate the fresh air valve
  • If the concentration is below a threshold value, the air flow is at minimum, if it is above, the flow rate is increased

Stand alone thermostats 33T

2 types of thermostats:
  • Type C : a two-pipe application equipped with EC motors
  • Type D : four or two-pipe applications equipped with electric heating and EC motor

Wall-mounted controls can easily and discreetly be integrated into any room environment. The operating range goes from 10°C to 30°C.
