Project Summary: Bear Valley Visitor Center, Heating System Rehab

Project Number: 17-22-024

This is a summary of TAB data collected on 8/25/2017.

Pacific test and Balance was asked to survey the heating systems serving the Bear Valley Visitor center. There are two air handlers that supply heating to this facility. S-1 serves Offices and other support areas. S-2 serves the auditorium. There are two recirculating supply fans (S-3/S-4) that serve the Exhibit Space that we could not access as it would require a large man lift. There are four ceiling mounted exhaust fans serving the restrooms and janitor closet that we read and recorded airflows for. Airflow readings were measured both by direct flowhood readings and duct traverses. Running performance data was also read and recorded for S-1 and S-2. See below for specifics on each system.

S-1

This air handler has a belt driven forward curved supply fan. The fan blades have a lot of dirt buildup that could be hindering the fans performance. The pleated filters looked new and clean. The motor has an adjustable sheave open to its minimum position. The total airflow measured at the outlets using the flowhood was 61% of design total specified on the mechanical drawings provided. The total airflow measured by duct traverse was 69% of design, with a difference of 185 CFM. There are two air terminals installed on this system which both serve the same two outlets. One is connected to the supply duct before the Furnace, and the other is connected after the discharge of the Furnace. Both of these terminals were found closed and not operating. They also look as though they are installed backwards to direction of airflow. The total return airflow measured was 77% of design, with a difference from the supply of 132 CFM. The OSA damper is 100% closed.

S-2

This air handler has a belt driven forward curved supply fan. The fan blades have a lot of dirt buildup that could be hindering the fans performance. The pleated filters looked new and clean. The motor has an adjustable sheave closed to its maximum position. This fan originally served four supply outlets in the auditorium. The last two have been removed and the ducted capped. There are currently only two remaining outlets. Both supply and return airflow’s for this fan were measured by duct traverse. There is no access for flowhood readings. Total supply measured was 69% of design total specified on the mechanical drawings provided. Total return airflow measured was 72% of design with a difference of 81 CFM. The OSA damper is 100% closed.

E-1

This ceiling mounted exhaust fan was measured at 53% of design specified.

E-2

This ceiling mounted exhaust fan was measured at 17% of design specified.

E-3

This ceiling mounted exhaust fan was measured at 47% of design specified.

E-4

This ceiling mounted exhaust fan was measured at 56% of design specified.
