Feasibility of Chilled Beam Systems in Building Industry

Abstract

In recent years, sustainability and efficiency have made their way to the forefront of building design. The concept of green buildings is one such measure to achieve sustainability by using passive measures and renewable energy sources to function a building. Apart from this, there are also increased concerns about maintaining a proper indoor environment for the building's residents at all times. In addition to temperature control, a fully functional HVAC system must address a variety of other indoor environmental challenges that affect occupant comfort, productivity, and health, including ventilation, air dispersion, humidity control, noise levels, and so on. Chilled beams have emerged as the most environmentally friendly solution for achieving these goals. The chilled beam system provides good thermal comfort and energy conservation due to the high heat capacity of the water used as a heat transfer medium. It is a low-energy HVAC system that uses dry cooling to operate. When compared to a standard air-conditioned building, a chilled beams system would be explored, which would demonstrate energy conservation and have the ability to save 30-40% of HVAC energy use. Originally designed to replace passive radiant cooling ceiling systems, chilled beams allow designers and engineers to maximize their space by drastically reducing cumbersome supply and return air ducts to the bare minimum required to meet ventilation needs. Smaller water pipes and more efficient hydronic systems serve heating and cooling demands. Chilled beams are a smart choice for both new construction and retrofits. The technology has yet to reach its full potential, and it is frequently disregarded for projects where it would be the most appropriate solution. This is mainly because of the lack of awareness and expertise in the construction industry, and it has highlighted the need for efficient flow of information between manufacturers, engineers, architects, and contractors.
