5.1?Heat Gain to SpaceThis test method determines the heat gain to the space from a hood/appliance system. Note 2:?To maintain a constant temperature in the conditioned
space, this heat gain must be matched by space cooling. The space
sensible cooling load, in tons, then equals the heat gain in Btu/h
divided by the conversion factor of 12 000 Btu/h (3.412 W) per ton
of cooling. Appliance heat gain data can be used for sizing air
conditioning systems. Details of load calculation procedures can be
found in ASHRAE, see Ref 5.2?Parametric
Studies:?
5.2.1?This test method also can be used to conduct parametric studies of alternative configurations of hoods, appliances, and replacement air systems. In general, these studies are conducted by holding constant all configuration and operational variables except the variable of interest. This test method, therefore, can be used to evaluate the following: 5.2.1.1?The overall system performance with various appliances, while holding the hood and replacement air system characteristics constant. 5.2.2?Entire hoods or characteristics of a single hood, such as end panels, can be varied with appliances and replacement air constant. 5.2.3?Replacement air characteristics, such as makeup air location, direction, and volume, can be varied with constant appliance and hood variables. |

|
1.1?This test method covers the determination of appliance heat gain to space derived from the measurement and calculation of appliance energy consumption, energy exhausted, and energy to food, based on a system energy balance, parametric evaluation of operational or design variations in appliances, hoods, or replacement air configurations. 1.2?The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.3?This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4?This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. |
