How Do Water Coils Work?

Diving into the Deep End of Water Coil Construction and Performance

What actually happens when you press the “up” button on the thermostat? What makes the air “hot”? Moving heat in and out of buildings is more complex than simply heating and cooling the outdoor air. While outdoor air is typically preconditioned before becoming primary system air, there is often a need for further cooling or reheating for thermal comfort purposes.

Stepping into the World of Fluid Dynamics

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.)

Promoting Healthy Indoor Air Quality in the Classroom

As HVAC professionals, one of our primary goals is to promote healthy indoor air quality in all spaces, and there are fewer applications where this is more important than in classrooms. It is estimated that approximately half of public school districts need to update or replace the HVAC systems in their schools.1

Determining the Right Amount of Airflow for a Space

At Price, we pride ourselves on being industry leaders in room air distribution. Our manufactured products are designed around a common goal: to keep the room air clean, dry and comfortable. This is often accomplished by blowing a jet of conditioned, fresh air through a grille, register or diffuser (GRD) throughout a room to properly ventilate it.
