Chilled Beams HVAC System

Understanding Chilled Beams HVAC System

Chilled beams are the most widely installed HVAC systems across the globe. It provides pleasant heating and cooling through an integral coil that is installed within a space. Chilled beams make less noise and have low-cost of maintenance.

The primary advantage that chilled beams provide is a reduction in energy wastage. Since they need fewer air drafts for the flow operations, they lead to minimal energy consumption. Chilled beams provide a consistent indoor air temperature and maintain it throughout their life.

Types of Chilled Beams HVAC Systems

There are two types of chilled beam systems – Active chilled beams and passive chilled beams.

Active Chilled Beams

Active chilled beams have a primary air supply and consist of fin-and-tube heat exchanger contained in the ductwork. Mostly, people use them for sensible cooling, heating, and ventilation of large and small spaces. As a primary source for air conditioning, they work and provide air throughout the space.

The heat exchanger is suspended in the ceiling of the building or office space. The air flows through the nozzles that result in air induction through a cooling coil installed in the system. The process of induction through cooling coils allows active chilled beams to provide more cooling than the passive ones.

Active chilled beams are most commonly used and offer code-required outdoor ventilation air. Facilities like offices, classrooms, healthcare facilities and other places where heat ratio is moderate, active chilled beams are used to maintain the temperature. Even in locations with limited space for mechanical space, active beams are an excellent choice.

Passive Chilled Beams

Passive chilled beams do not have any kind of ductwork. However, a suspended fin-and-tube heat exchanger is also part of their design. There are tubes through which the chilled water flows.

Passive chilled beams do not supply primary air, and they have no fan-powered equipment for the air that flows through the cooling coil. After reaching the ceiling through natural buoyancy, warm air cools down as it surrounds the beam. It then descends towards the open space again, and the whole process works in kind of a back and forth motion.

The cooling coil releases descending air, while fresh air rises and reaches the ceiling where the passive chilled beam is installed. They actively install these beams in locations with high heat loads and warm temperatures. Passive chilled beams are a perfect choice for labs and other scientific spaces that require maintaining a warm temperature.

While some spaces have active chilled beams, they can utilize passive beams as supplementary sources of cooling. If you want to keep the existing ventilation system and need to maintain the space in the room, passive chilled beams can be used.

How Does an Active Chilled Beam Work?

An active chilled beam operates by utilizing a combination of convective and radiant cooling principles to efficiently cool a space. The chilled beam, a component of the HVAC system, typically installs in the ceiling or within the space. It consists of a coil that circulates chilled water, and a primary air supply.

The process starts when the chilled beam receives primary air supplied from the HVAC system. As the primary air passes over the coil, it transfers heat from the air to the coil, resulting in the cooling of the air. Simultaneously, the chilled water circulating through the coil absorbs the heat from the air.

The system discharges the cooled air into the space, creating a comfortable and refreshing indoor environment. The chilled beam also emits radiant cooling, which further contributes to the overall cooling effect. The warm air in the space naturally rises and is drawn toward the chilled beam, which cools it, creating a natural convection cycle.

Using active chilled beam technology efficiently cools spaces while minimizing energy consumption. Additionally, active chilled beams offer a quiet operation, improved indoor air quality, and the ability to integrate with various architectural designs. Learn more.

What Is a Passive Chilled Beam?

A passive chilled beam is an HVAC system component that provides cooling to a space without the need for a dedicated air supply. Unlike an active chilled beam, which uses a primary air supply to induce the cooling process, a passive chilled beam relies solely on convection and radiation for cooling.

Passive chilled beams typically consist of a finned coil that circulates chilled water. When the warm air in the space comes into contact with the chilled surface of the beam, heat transfer occurs, cooling the air. The cooled air then naturally sinks, creating a convection current that helps distribute the cool air throughout the space.

Since passive chilled beams do not require a separate air supply, they operate silently and are energy-efficient. Integrating them into various ceiling or architectural designs makes them aesthetically pleasing and unobtrusive. However, it’s important to note that passive chilled beams may have a lower cooling capacity compared to active chilled beams and are more suitable for applications with moderate cooling loads.
