Responsibilities

• Prepare engineering man-hour estimates for HVAC scopes.
• Perform building and room heating and cooling load calculations.
• Size and select HVAC equipment, and prepare equipment specifications and data sheets.
• Produce HVAC design drawings, including layouts, ductwork, piping and details, and HVAC control P&IDs.
• Write HVAC work scopes for contractors and equipment suppliers.
• Evaluate equipment and contractor bids technically, and make recommendations.
• Review and approve HVAC equipment submittals against the design intent and project specifications.
• Support commissioning of HVAC equipment and systems, including start-up, testing and issue resolution.
• Coordinate with other disciplines (mechanical/piping, electrical, structural, controls) and with clients, vendors and field personnel.

Equipment

• Working knowledge of how an air conditioning and refrigeration system operates; service experience is a plus but not required.
• Air-cooled vs. water-cooled systems, chilled water systems, packaged units and split systems.
• Air-cooled and water-cooled condensers, chillers (air-cooled and water-cooled), and cooling towers and their purpose.
• Compressor types: hermetic, semi-hermetic and screw; and the differences between screw and centrifugal chillers.
• Carbon filter air units and their purpose.
• Heaters: gas, electric, steam, duct-mounted and unit heaters.

Technical

• Heating and cooling load calculations for a room, building or structure, including infiltration (typically 15% to 25%), U-factors/R-values, solar loads, and sensible and latent loads.
• Determining when a system is sized on sensible vs. latent load, and what increases latent capacity.
• Psychrometrics: dry bulb, wet bulb, dew point, relative humidity, enthalpy, grains per pound of dry air, evaporation and dehumidification, and how they relate.
• Calculating mixed air temperature; conversions among hp, Btu/h and kW; single-phase vs. three-phase power.
• AC control strategies, including what drives dehumidification and how to control humidity.
• Sizing electric heaters by temperature rise vs. temperature differential (envelope loads).
• Air changes per hour for an envelope and ventilation design strategy, including heating and ventilating a warehouse or boiler building.
• Ventilation methods: cross-flow, push-pull and stack effect.
• Duct design and fabrication: SMACNA requirements, CFM, constant velocity and static regain methods, and which fittings can be fabricated and in what configurations.
• Refrigerants: pure vs. blends, GWP, ODP, A2L classification and the requirements for using A2L refrigerants.
• Piping: refrigerant piping types and insulation; chilled water piping material, insulation and velocity.
• Pipe design experience is a plus.

Software
