Abstract
ABSTRACT Four different identical 100 percent outdoor air HVAC (heating, ventilation and air conditioning) systems with total enthalpy control were evaluated in four locations for a base system, an HRV (heat recovery) system, and an ERV (enthalpy recovery) system. The locations were in New York, NY; Atlanta, GA; Omaha, NE; and Sacramento, CA. The four base systems were evaluated under design conditions for both cooling and heating. An HRV (heat recovery ventilation) system was added, then the change in heating and cooling loads from an energy cost standpoint were tested. This was repeated with an ERV (enthalpy system), and again the energy savings were tested and recorded. Infrared thermal analysis was also used to explain and further evaluate and detail the thermal performance and characteristics of different HVAC components. At a national ASHRAE seminar session, this presentation was well received and peer reviewed. Talking about energy savings is one thing, but actually seeing them is very interesting!
