Characterization of cooking effluent from seven commercial kitchen appliances and representative food products. ASHRAE’s document [1], “Thermal Guidelines for Data Processing Environments– Fourth Edition” has increased the industry’s awareness of the effect increased operating temperature can have on IT equipment. As the percentage of building energy use from plug loads continues to grow, a new standard from ASHRAE will help building professionals estimate the heat gain of equipment. considers both latent heat gain due to heat sources within the residential space, and sensible heat gains due to heat sources outside the residential space. This paper. https://www.thefreelibrary.com/Revised+heat+gain+rates+from+typical+commercial+cooking+appliances...-a0217848196, Swierczyna, Rich; Sobiski, Paul; Fisher, Don. The heat gain data for office equipment from RP--822 and RP--1055 have previously provided useful and necessary information for load calculations; however, computer, printer, and copier technology changes and the introduction of flat-panel monitors in recent years have necessitated an update in data for total heat gain and the split between convective and radiant loads for such office equipment. At least 80 hooded and un-hooded equipment types will be tested. A latent heat gain is the heat contained in water vapor. Notes recent research by ASHRAE into measuring actual heat gain and radiant and convective split from equipment in buildings and the application of the developed methodology to a wide range of equipment. A properly designed direct evaporative cooler reduces the ASHRAE is the industry organization that sets the standards and guidelines for most all HVAC-R equipment. Latent load is the heat that must be removed to condense the moisture out of the air. For webmasters. or. Elevators loads etc.....
