The Science of ComfortTM
As HVAC systems evolve to meet increasingly demanding energy codes and sustainability goals, chilled beams are emerging as a compelling solution. Their popularity is driven by their ability to deliver long-term energy savings, reduce duct sizing, lower noise levels and minimize maintenance requirements.

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.

The most challenging class from my university days was a grad-level course on thermal convection. For four months, our professor rederived our favorite fluid mechanics equations using partial differential equations. (I scraped by with a C+ and learned just enough about Navier-Stokes equations to sound pretentious.)

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.

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.
