The Science of ComfortTM
In the HVAC industry, an application-specific controller is a device that comes preprogrammed with a sequence of operations for the equipment it’s intended to control. This could be anything from a boiler or air handler to a rooftop unit or terminal unit.

Understanding how much space a fan coil unit needs is imperative for mechanical system design. Incorrect assumptions can create deviations between contract documents and finished buildings, which can lead to change orders and increased project costs for building owners. The type of fan coil unit, the options it is configured with and the overall design of the building’s HVAC system all influence the final installation requirements.

In the world of air distribution, a drop box is a plenum with multiple air outlets that is connected directly to an air handling unit (AHU) by a short run of ductwork. A drop box can be an effective way to deliver a substantial volume of conditioned air to large, enclosed spaces.

Air-to-water heat pump systems are highly efficient HVAC solutions, but optimizing their performance depends on addressing key factors – most notably, the hot water supply temperature (HWST). And when these heat pumps are paired with a VAV distribution system, it’s especially critical to select the correct coil configuration.
