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].

Prevent Condensation from Becoming a Design Flaw

Water condensation is easily the most common concern when discussing chilled beams and cooling panels. This concern comes from the personal experience many have had of seeing water droplets form on the surface of piping such as a water coil.

Induction in Chilled Beams and Diffusers

ACTIVE CHILLED BEAMS

In a chilled beam, the term “induction” is used to describe the process of injecting primary air under pressure through a nozzle, which in turn entrains return or plenum air at the discharge of the nozzle.

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.

Silence is Golden: Optimizing the Acoustic Environment

Posted by Alex Michaud on June 14, 2019 at 10:02 AM

Noise is the number one occupant complaint.

Research indicates that hospital patients and staff, hotel guests, and restaurant diners complain about noise more than anything else. Noise can impact occupants by lowering productivity and increasing stress levels. This “invisible” problem is loud and clear.

Properly addressing all noise sources allows building occupants to be more comfortable and productive.
