ASHRAE AB-10-025, 2010 Edition, 2010 - Heat Gain from Electrical and Control Equipment in Industrial Plants—Part 2 ABSTRACT RP-1395 is a continuation of an earlier project where the heat dissipated by indoor power distribution equipment is estimated. Commercial kitchens and dishrooms house equipment that generate the most intensive concentrations of sensible and latent loads. 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. The ASHRAE HVAC Applications Handbook 1999 [ASHRAE 1999, p. 13.2] recommends that the designer “…should evaluate equipment nameplate ratings, appli-cable use and usage factors, and overall diversity.” However, due to the lack of data on these parameters, it is often difficult to analytically derive the equipment loads.1 0000006400 00000 n when we say unhooded equipment we have two cases: 1- the equipment itself is not directly under a hood but there is a hood in the same space 2- there is no hood at all in the same space ASHRAE tables provide very good help but you have to read the ASHRAE book too not only tables. heat load calculation for kitchen equipment,heat gain from kitchen equipment ashrae,heat load kitchen equipment,heat gain from commercial kitchen equipment Document History. The average amount of heat given off by a person depends on the level of activity, and can range from about 100 W for a resting person to more than 500 W for a physically very active person.

ASHRAE TC9.9 recommends the equipment be designed to withstand a higher inlet air temperature than the data center cooling supply air if: a) the equipment is installed in an enclosed space that doesn’t have direct access to the data center air cooling stream, or b) the The equipment items not covered in this paper are medium and low-voltage switchgear and adjustable speed drives. 0000006857 00000 n ASHRAE is the industry organization that sets the standards and guidelines for most all HVAC-R equipment. Commonly, heat gain from equipment in a laboratory ranges from 50 to 220 W/m 2 or, in laboratories with outdoor exposure, as much as four times the heat gain from all other sources combined.
