APPENDIX B. ENGINEERING DATA 

B.1 INTRODUCTION 

This appendix presents baseline specifications and detailed cost-efficiency results for 

each of the three sizes in the beverage vending machine equipment classes analyzed in the 

engineering analysis (chapter 5). 

B.2 BASELINE DESIGN OPTIONS 

Table B.2.1 shows the baseline design options for each size of each equipment class. 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.

B.3 COST-EFFICIENCY RESULTS 

For each size and equipment class analyzed in the engineering analysis, Figure B.3.1 

through Figure B.3.6 show cost-efficiency curves and Table B.3.1 through Table B.3.6 show 

detailed cost-efficiency data. Cost-efficiency data and technology changes that occur above the 

baseline level are included in each table. 

Design option changes above the baseline are shown in Table B.3.1 through Table B.3.6 

as additions to the previous design option level. For example, in the Type A small product class,

“0 + PSC Condenser Motor” would indicate that the condenser fan motor technology in the 

baseline level (shaded pole motor, SPM) was replaced with a permanent split capacitor (PSC) 

motor. Design options are implemented from the lowest to highest payback and only one design 

option change is made per design option level.
