1.0 Executive Summary

The objective of this report is to evaluate the suitability of retaining the existing duct sizes when the existing ductwork in the Visitor’s Center at the Nez Perce Historical Park is replaced under a separate project. There are 10 split-system fan-coil (FC) systems with electric backup heat currently serving the building. Calculations indicate that the existing duct systems are adequately sized for the equipment, except for two branch ducts connected to FC-6. Exhibit C shows the revised duct and diffuser layout, with additional notes pertaining to special construction and coordination items required for re-use of humidifiers / dehumidifiers, duct smoke detectors, dampers and carbon filters.

1.1 Project Background

In 2014, the water-source heat pumps and air handlers serving the Visitor’s Center were replaced with air-source fan-coil / heat pump systems designed to match the original systems’ capacities. Under the 2014 project, the existing ductwork was retained and re-used.

The existing ductwork has fiberglass lining which is deteriorating, necessitating more frequent filter changes and duct cleanings. The owner therefore intends to replace the existing ductwork. DC Engineering (DCE) has been tasked with evaluating whether the existing duct systems may be replaced in kind, and where duct sizes are found to be deficient, to provide corrected sizing.

The duct systems were evaluated based on SMACNA’S “HVAC Systems Duct Design” manual, along with Carrier Corporation’s “System Design Manual” air distribution volume.

General notes regarding the evaluation method:

• It is assumed that the duct sizes shown on the original drawings represented the free area.

• Calculations assume that changes in direction greater than 45° will have turning vanes. Bullhead Tees are assumed to incorporate turning vanes.

• It should be noted that the FC units 2, 5, 6 & 7 scheduled in the 2014 renovations are larger capacity units than those in the original design. The evaluations were conducted based on the 2014 CFM values.

In addition, a survey of the site indicated that the humidification and dehumidification systems serving the Storage area (002) and Exhibits area (102) are not functioning. These will require placement in order to maintain the proper humidity levels for museum collections (50% ± 10%) as requested by the owner.

2.0 Conclusions and Recommendations

All the existing duct systems may be replaced like for like and function as designed, except for two branches connected to FC-6 which require a slight increase in size. The duct static calculations for existing systems are shown in Exhibit A, and Exhibit B contains a “duct map” showing the segments corresponding to the segment names shown in the calculation sheets.

A revised mechanical plan is shown in Exhibit C. This includes the existing duct sizes and updated sizes serving the Admin Clerk Office, Room 115, and the Open Office, Room

114. It also shows new diffusers (except for custom diffusers/grilles retained in rooms 101 and 102) and airflows for balancing purposes and contains additional notes regarding the installation of ducts in the vicinity of the humidifiers, existing carbon filters, and the mixing boxes serving the Exhibits Room (Room 102). In addition to the work described above, these plans include the new humidifiers and dehumidifiers noted in the project background section. As a cost-saving measure, a deduct alternate specifying re-use of the existing grilles / diffusers may be requested.

As noted above, some HVAC units are larger than in the original design. Where this is the case, the additional airflow has been proportionally distributed between the air inlets and outlets.
