The Science of ComfortTM
Water-to-air heat exchangers are commonly used throughout commercial HVAC systems. The amount of fluid flowing through a coil directly influences the temperature exchanged to the air, which ultimately impacts the thermal comfort of those in the space. Both the type and size of piping package components are important to ensure that the overall system is running efficiently and to optimize thermal comfort.

Silencers, also referred to as sound attenuators or sound traps, are used as part of the HVAC system to reduce the noise that would otherwise be transmitted to the nearest indoor or outdoor space. In large commercial or industrial applications, silencers can be used in large banks to prevent noise from transferring into the environment.

Although perceived as an up-and-coming technology, chilled beams have been around for years. This system offers many benefits, including energy savings over the lifespan of a project, reduced duct sizing, lower noise levels and minimal required maintenance.

In modern buildings, the heating, cooling, and ventilation systems consume a large portion of the total energy use. This creates an obvious target when looking for areas where improvements and optimizations can reduce annual energy consumption. Costs associated with these improvements can be reduced year over year. Within the HVAC system, the largest consumer of energy will typically be fan energy. Using hydronic systems to transport heating or cooling energy throughout a building is a great way to dramatically reduce the overall energy consumption of the entire HVAC system.

The fan column is a vertical fan unit designed to discharge air into a raised access floor plenum. The unit may be likened to an air handler as it mixes filtered, cooled return air with pre-treated outside air typically from a dedicated outdoor air system (DOAS) to achieve the design supply air temperature, then discharge the mixed air into the raised access floor plenum.
