Standard Test Method for Heat Gain to Space Performance of Commercial Kitchen Ventilation/Appliance Systems

Importancia y uso:

5.1 Heat Gain to Space—This 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 (1) and Ref (2)5. The calculation of associated cooling loads from heat gains to the test space at various flow rates can be used along with other information by heating, ventilation, air conditioning (HVAC), and exhaust system designers to achieve energy-conservative, integrated kitchen ventilation system designs.

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.
