Using Computational Fluid Dynamics to Optimize HVAC Design

Posted by Price Industries on June 16, 2020 at 10:01 AM

Leverage the power of simulation on your next building design

High demands are placed on modern HVAC systems to create optimal indoor environments while minimizing energy usage. Consequently, usage of computer-based analysis tools like computational fluid dynamics (CFD) that aid in the design of these systems is becoming more prevalent. With the recent addendum to ASHRAE 62.1 we expect the demand for CFD analyses to increase even further. The change states that a CFD analysis can be used to estimate the ventilation effectiveness value used to determine the outdoor air requirement instead of tables provided in the standard.

Fan Filter Units in Retrofit Isolation Rooms

Posted by Price Industries on March 26, 2020 at 9:16 AM

Application of Fan Filter Units in Airborne Infection Isolation Rooms 

Airborne infection isolation rooms (AIIR) are used for patients with easily communicable airborne disease. When there is a shortage of AIIR, existing patient rooms (or hotel rooms in temporary care facilities) can be converted to negative pressure isolation rooms. Price Fan Filter Units (FFU) can be used in three configurations to retrofit these existing spaces.

Swimming Pool Ventilation

Posted by Price Industries on March 24, 2020 at 12:03 PM

Design Considerations for Natatorium Ventilation

Designing a ventilation system for a swimming pool can be tricky. For occupant comfort, these facilities require 40 to 60% relative humidity to be maintained year round. For swimmers, a humidity range of 50 to 60% is most comfortable. However, humidity levels below 50% can significantly increase energy consumption, while humidity levels above 60% can cause damage due to mold, mildew and condensation.
