## 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 (c hapter 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

. A ll changes to cost and efficiency are measured relativ e to this level in the engineering analysis

. Refer to

c hapter 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 , t he baseline specifications define the energy consumption and cost of the lowest

- efficiency equipment which DOE analyzed in developing this preliminary analysis.
