The Science of Comfort

Swimming Pool Ventilation

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.

What is Inlet Effect?

Inlet Effects

ASHRAE Standard 70 guidelines are in place so that ideal conditions are present during GRD testing

and to ensure the testing is repeatable. It is important to note that the performance

published in the Price catalog is based on these ideal conditions outlined in ASHRAE 70 and that

any field modifications can affect the performance of the outlet. There are five common field conditions and their influence on the air pattern of a given diffuser:

Hard 90 Degree Elbow
90 Degree Flexible Duct Elbow
Radial Opposed Blade Damper
Butterfly Damper
Radial Damper

Low Temperature Air Distribution

Posted by Price Industries on August 13, 2019 at 8:59 AM

Low temperature overhead air distribution (also called cold air distribution) supplies cooling air to the occupied space with an entering air temperature typically between 40°F and 50°F [4.4 and 10°C]. This contrasts to the “typical or conventional” overhead air distribution cooling supply air temperature between 50°F and 59°F [10 and 15°C].

Creating Lasting Impressions with Customer Mock-ups

Posted by Price Industries on July 2, 2019 at 9:26 AM

In the HVAC design world, there is some uncertainty about the application of new and existing air distribution technologies since codes change so quickly and sometimes drastically. Customer mock-ups of the proposed HVAC design for a specific space are a great way to help resolve design uncertainty.
