This project is needed to develop a comprehensive reference set of analytical solutions that are well-documented, peer-reviewed, and stated appropriately for use in testing simulation software. This work will assist users of SPC 140 SMOT by expanding the range of mechanical systems for which reference solutions are available. This work will be published as a supplement or incorporated into a future revision to SPC 140 SMOT, which will widen its acceptance and applicability.

The objective of this research project is to develop and document a reference set of steady-state analytical solutions for secondary HVAC systems. These solutions will show step-by-step the calculation of airflows, air temperatures, and coil loads given specifications of system configuration, space loads, space temperatures, and outside air conditions. They will demonstrate the application of these solutions for testing of simulation software by developing DOE-2 and BLAST input files for each case and comparing the simulation results with the analytical solutions.
