Chilled Beam Hvac System

A chilled beam is a type of radiation convection hvac system designed to heat and cool large buildings.

Chilled beam hvac system.

When you have a central air conditioning unit or a rooftop unit large fans must move the cooled air through the building via large air ducts. An alternative to a conventional vav system this chilled beam cooling device separates ventilation and dehumidification. A chilled beam system is designed for use in non residential applications where there is a high temperature load and or rooms that require individual comfort control. Chilled beam systems were designed to reduce energy waste.

Active linear vertical coil chilled beam. Active chilled beam for use in recessed applications. It s made of copper tubing and bonded to aluminum fins. It is replaced by warmer air moving up from below causing a constant passive air movement called convection which cools the room.

Energy efficient chilled beam systems maintain a comfortable indoor climate with york chilled beams. 24 inch width active linear chilled beam with 1 way or 2 way throw. Sill mounted concealed active chilled beam. A chilled beam system is an hvac system used to heat and cool large buildings.

Pipes of water are passed through a beam either integrated into standard suspended ceiling systems or suspended a short distance from the ceiling of a room. It s housed in a sheet metal enclosure and is usually placed at ceiling level. Separate heating systems e g finned tube radiators electric baseboard duct heaters are often required in heating dominated climates with a chilled beam system. As the beam chills the air around it the air becomes denser and falls to the floor.

Since large buildings require large amounts of energy to keep cool the idea of a chilled beam system is to use natural convection warm air rises cool air falls and the superior energy capacity of water to make cooling much more economical. The chilled water must be relatively warm typically between 58 f and 60 f to prevent condensation. Explore hvac chilled beam systems. Chilled beams utilize the reduced density of cold air to induce flow and are therefore less effective at providing heat to a space.

Heating works in muc. Fläktgroup semco s chilled beams are designed to manage high cooling capacity by using a primary air supply typically outdoor air to increase airflow over the element. The active beams use a dedicated outdoor air system doas to supply the spaces with cool dry air to satisfy the latent loads as well as the ventilation requirements. The water coil in the chilled beam a two pipe system for either cold or hot water or a four pipe system for simultaneous heating and cooling is controlled by the space thermostat and satisfies the space sensible load.

1 deliver at least the required amount of outdoor air to each space for ventilation and 2 deliver air which is dry enough to offset the space latent load and maintain the indoor dew point low enough to avoid condensation on the chilled beams and 3 deliver enough air to induce. Low profile terminal with sensible cooling coil for outside air.
