Fundamentals and Applications
Chair:
Jeff Stein, P.E., Taylor Engineering, LLC
Technical Committee: 4.1 Load Calculation Data and Procedures
CoSponsor: 5.10 Kitchen Ventilation
This session presents the results of ASHRAE research projects that updated the office equipment and kitchen appliance heat gain tables in the Fundamentals Handbook Chapter 18, Nonresidential Cooling and Heating Load Calculations. The office equipment heat gain project was research project RP-1742, Update to Measurements of Office Equipment Heat Gain Data. The kitchen appliance heat gain project was RP-1631, Countertop Commercial Appliance Emissions.
1 RP-1742 Update to Measurements of Office Equipment Heat Gain Data: Experimental Approach and Results Overview
 |
Christian Bach, Ph.D., Oklahoma State University |
This seminar introduces the experimental approach and selected test sites used to update the heat gains and diversity factors for different office equipment in the ASHRAE Fundamentals handbook tables. The seminar gives an overview on the data logger’s selection criteria for measurement and calibration purposes as well as the testing duration for different equipment. An overview of the experimental results for both, heat gains and diversity factors is also given. Transient data is shown and some typical and atypical findings are pointed out.
2 RP-1742 Update to Measurements of Office Equipment Heat Gain Data: Data Analysis and Parametric Studies
 |
Omer Sarfraz, Oklahoma State University |
This seminar gives an overview of methods used for the determination of recommended heat gains and diversity factors for different office equipment in the ASHRAE Fundamentals Handbook tables. In particular, the effects of a number of tested pieces of equipment as well as the interval duration for data reduction are investigated. Analysis on the effect of the different number of tested pieces of equipment and averaging interval on the diversity factor is also discussed. Recommendations for minimum equipment count for determining diversity factors as well as recommendations for future work are given.
3 RP-1631 Update to Kitchen Appliance Heat Gain Data
 |
Rich Swierczyna, Fisher-Nickel |
Commercial kitchens and dishrooms house equipment that generate the most intensive concentrations of sensible and latent loads. This seminar presents the heat gain findings from RP1631 Countertop Commercial Appliance Emissions along with the updates to the appliance heat gain tables in the handbook.
