Thesis Proposal

The thesis proposal contains a discussion about changes that will be investigated for the designed mechanical system at the current WRNMMC. The proposed topics of change involve decentralizing the supply air fans, utilizing backpressure steam turbines, and a combined heat and power investigation.

Depth Topics:

A study on the effects of decentralizing the current supply air fans in the basement spaces will take place to analyze the potential energy savings from having smaller fan motors. In order for this alternative to be viable the fan energy savings must offset the additional cost from the added fans throughout the system

An investigation into replacing the steam pressure reducing stations with backpressure steam turbines will be performed to quantify the amount of electricity generation potential and payback period.

Combined heat and power will be studied to determine the potential savings due to electricity generation while recovering heat to create steam. This combined heat and power analysis will also look into the incorporation of backpressure steam turbines for the steam pressure reducing requirements.

Breadth Topics:

An investigation into external electronically controlled solar shading will be performed. The quantity and quality of light entering the space will also be evaluated. Potential load reduction due to reduced heat gain may result in decreased mechanical equipment sizes.

With the addition of new mechanical equipment an acoustical analysis will be performed in the mechanical rooms to determine that the new noise levels will not be disturbing to the surrounding spaces.

MAE Incorporation:

I be utilizing information gained from HVAC Central Cooling and Distribution Systems (AE 557) to help in changing the central utility plant. Combined Heat and Power (AE 551) will be utilized during the backpressure steam turbine and combined heat and power analysis. Life cycle cost and payback period information will be calculated using the techniques and materials presented in Central Heating Systems (AE 558).
