The Science of ComfortTM
VAV diffusers help keep rooms comfortable using an individual thermostat and a built-in damper to create small zones of control. The amount of air provided by the VAV diffuser is based on three factors: the temperature in the room, the room’s set point and the temperature of the supply air.

Operating rooms (ORs) come in many varieties depending on the type of surgeries performed in them. A hybrid OR, for example, is home to large imaging equipment, whether that’s a CT scanner or an MRI machine.

When it comes to designing an HVAC system, the moisture content of the air within a space is just as important as the supply air temperature. In a system with active chilled beams, the moisture content becomes a critical factor, so it is important to understand the concept of moisture depression.

Displacement ventilation (DV) systems are revolutionizing how large spaces are cooled and ventilated. Although mostly known for their ability to provide exceptional indoor air quality, DV systems can also reduce total airflow requirements in certain applications.

Single-zone HVAC solutions come in many shapes and sizes, but space is always at a premium. Using hydronic distribution for heating and cooling is a great way to minimize a system’s footprint – and it’s a perfect fit for single-zone fan coils.
