About this file
This is a comprehensive mechanical calculations document for the replacement of an Air Handling Unit (AHU) in Building 45 at the Edward Hines Jr. VA Hospital in Hines, Illinois, as part of Project Number 578-17-012. The file contains detailed technical calculations including peak heating and cooling loads for multiple zones, ventilation calculations, humidifier sizing, psychrometric analysis, hydronic piping system loss calculations, duct static pressure loss calculations, steam and condensate pipe calculations, and relief valve calculations. The calculations cover various systems including AHU-1, MAU-1, chilled water supply and return, glycol systems, hydronic systems, steam systems, and condensate systems, providing extensive engineering data to support the AHU replacement project.
The document includes precise technical specifications such as air flow rates, temperature differentials, pressure drops, pipe sizes, friction factors, and system volumes across multiple mechanical systems. Key parameters examined include steam pressures ranging from 15 to 60 psig, steam rates between 300 and 2,100 lb/hr, pipe diameters from 1 to 4 inches, and calculations for different system pressures and temperatures. The calculations are designed to ensure proper sizing, performance, and efficiency of the mechanical systems involved in the AHU replacement, with methodical analysis following engineering standards like ASHRAE guidelines and ASME B31.1 specifications.

GENERAL NOTES:
1. COOLING CFMS CALCULATED AT 617 FT ELEVATION WITH A SUPPLY AIR TEMPERATURE OF 55⁰F AND A COOLING SETPOINT OF 75⁰F.
2. HEATING CFMS CALCULATED AT 617 FT ELEVATION WITH A SUPPLY AIR TEMPERATURE OF 90⁰F AND A HEATING SETPOINT OF 70⁰F.
3. MINIMUM AIRFLOW (IN MOST CASES, THIS IS THE HEATING AIR FLOW RATE) USED FOR AIR CHANGE CALCULATIONS.
Directions:
Sensible peak room cooling load: From trace room checksums, sum the space peak envelope loads, the space peak internal loads and the space peak ceiling load.
Latent peak room cooling load: From Trace room checksums, subtract the people sensible load from the total people load.
