Chilled Beam Hvac System

An alternative to a conventional vav system this chilled beam cooling device separates ventilation and dehumidification.

Chilled beam hvac system.

Separate heating systems e g finned tube radiators electric baseboard duct heaters are often required in heating dominated climates with a chilled beam system. Sill mounted concealed active chilled beam. 24 inch width active linear chilled beam with 1 way or 2 way throw. 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.

It is replaced by warmer air moving up from below causing a constant passive air movement called convection which cools the room. Heating works in muc. It s made of copper tubing and bonded to aluminum fins. Engineered for compatibility with a low height ceiling void every chilled beam we offer features near silent operation and minimal maintenance requirements.

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. Active chilled beam for use in recessed applications. 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. Chilled beams utilize the reduced density of cold air to induce flow and are therefore less effective at providing heat to a space.

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. Chilled beam systems were designed to reduce energy waste. 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. Air system for active chilled beams is to.

It s housed in a sheet metal enclosure and is usually placed at ceiling level. 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. As the beam chills the air around it the air becomes denser and falls to the floor. 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.

Active linear vertical coil chilled beam. A chilled beam system is an hvac system used to heat and cool large buildings. Energy efficient chilled beam systems maintain a comfortable indoor climate with york chilled beams. Even with variable speed fans the cost to move the air through a large building can be significant.

The chilled water must be relatively warm typically between 58 f and 60 f to prevent condensation. Explore hvac chilled beam systems.
