Sontay, manufacturer and distributer of building measurement and control peripherals, offers a complete range of sensors to control and monitor chilled beams. These water-based cooling systems are environmentally friendly and unobtrusive making them a popular choice for commercial buildings such as offices, hotels and hospitals
“As well as reducing energy consumption, chilled beams or chilled ceilings improve comfort levels for occupants,” says Sandy Damm, Managing Director at Sontay. “They can reduce the risk of draughts and eliminate the intrusive noise and aesthetic problems associated with more conventional solutions. Chilled Beams can be a great solution but they need to be controlled correctly to get the maximum benefit, which is why we have put together a complete range of temperature, RH, condensation and air velocity sensors.”
A chilled beam uses coils that exchange heat with the air in the room so the warm air rises, is cooled by the chilled beam and then falls back to the floor, where the cycle starts over. The ideal Sontay products to work alongside chilled beams include the WD-CPS Condensation Prevention Sensor, which detects the dew point on chilled surfaces such as chilled beams and adjusts accordingly. The TT-359 Direct Clamp-on Temperature Sensor will directly measure the pipe temperature along with the highly stable and reliable range of RH Sensors, GS-CO2 Sensors and Air Velocity Sensors.
Chilled beams of chilled ceiling systems are typically designed to use the dry cooling principle by selecting the ventilation rate, supply air conditions and chilled water flow temperature so that there is no risk of condensation. In order for it to work, the space air dew point temperature should be around 2°C lower than the flow temperature of chilled water in the ceiling or beam system. Chilled beams can be controlled in plenty of ways such as altering the rate at which air is supplied via an active chilled beam or varying the temperature of the air supplied.
