The Science of ComfortTM
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.

The original intention of the Price Engineer’s HVAC Handbook was to create a “polished compilation” of existing design guides and examples from the Price Catalog. In typical Price fashion, we dedicated more than 20,000 internal hours over the course of two years to create an industry-first reference guide on air distribution – complete with 1,350 pages and more than 3,000 illustrations.

When SolutionAir launched the RegenCore alternating mass-exchanger energy-recovery unit in 2019, the unit rocked the industry, delivering up to 92% effectiveness and no preheat requirement down to outdoor temperatures of −40°C/F. Its energy-recovery cores and four-damper design maximized energy conservation and minimized leakage, but combining the components meant RegenCore needed to be either mounted on a roof or concrete pad outdoors or installed in large mechanical rooms indoors.

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].
