Locomotive Ventilation System.

The primary responsibilities include developing the ventilation system for proposals, conducting design calculations, and selecting filters, blowers, and louvers that meet customer specifications. Additionally, it is essential to create the ventilation circuit to fulfill the flow specifications for various high-voltage and control panels, as well as to complete the airflow circuit balance and temperature projections. Filters and blowers are developed in partnership with the provider to meet project requirements utilizing the PPAP method. It is also important to provide the manufacturing team with all necessary support during the construction of the locomotive, ensuring that each component adheres to form, fit, and function requirements. To understand the different failure modes and to formulate a suitable verification and validation strategy, the DFMEA approach should be followed. The design must be reviewed with a global team at both the system and component levels.

Each design undergoes validation through FEA for structural analysis and CFD for flow and temperature distribution. Furthermore, assist customers with any ventilation issues that may occur during operation by engaging in reliability projects. Propose opportunities for design improvements and cost reductions. As part of my role, I was required to visit production facilities to conduct testing at both the component and system levels.

HVAC and Plumbing System:

The primary duties encompass the calculation of U-Value, heating and cooling loads utilizing Elite software, as well as determining equipment loads, system sizes, conducting psychometric analyses, sizing ducts, assessing external duct pressure loss, and estimating pump head. The selection of equipment, which includes air washers, unitary air filtration units, chillers, and AHUs, is also a critical task. Technical specifications are developed, vendors are evaluated, HVAC equipment is prepared, inspected, and reviewed, and schematics, schedules, and ducting plan drawings are produced. HVAC design must comply with local state codes, if applicable, as well as ASHRAE, CIBSE, NFPA, and IMC.

The key responsibilities further include the calculation of roof drains, sanitary drains and vents, pump heads, water supply calculations, and water heater calculations. Additionally, the selection of equipment, cost estimation using the RS Means cost data handbook, and interdisciplinary coordination are essential. Plumbing layout drawings, schematics, and schedules are created, verified, and reviewed using AutoCAD. The plumbing design adheres to the International Plumbing Code (IPC), Uniform Plumbing Code (UPC), and relevant local state codes, if necessary.
