APPENDIX 5A. ENGINEERING DATA

5A.1 INTRODUCTION

This appendix presents baseline specifications and other details for each of the 

refrigerated beverage vending machine analysis points modeled in the engineering analysis

(chapter 5 of the technical support document (TSD)).

5A.2 BASELINE SPECIFICATIONS

Table 5A.2.1 and Table 5A.2.3 show baseline design options for each of the refrigerated 

beverage vending machine analysis points modeled in the engineering analysis. All changes to 

cost and efficiency are measured relative to this level in the engineering analysis. Refer to 

chapter 5 of the TSD for details about each baseline technology.

Table 5A.2.2 and Table 5A.2.4 show baseline specifications for each of the beverage 

vending machine analysis points modeled in the engineering analysis. These specifications 

include dimensions, numbers of components, temperatures, nominal power ratings, and other 

case features that are necessary to calculate the energy consumption of each analysis point. In 

conjunction with baseline design option levels, the baseline specifications define the energy 

consumption and cost of the lowest-efficiency equipment which DOE analyzed in developing 

this preliminary analysis.
