AHU-03 Air Audit Notes

1. The supply fan VFD was not operating correctly. The supply fan has been wired around the VFD drive and is operating at a constant speed of 60 Hertz. Please see the attached picture.

2. A velocity matrix was performed at the discharge side of the cooling coil to determine the

Supply Fan CFM. The results are as follows.

3. Part of the final filter bank located inside the unit were not installed. Please see attached picture.

4. Return air is provided by RF-03. A traverse of the return air duct was completed in the penthouse. Those results are included in the RF-03 section of this report. The average reading of that process was 11,366 CFM. The outside air for AHU-03 was determined by subtracting 11,366 CFM of return air from 13,273 CFM of supply air. This equates to 1,907 CFM of outside air. The outside air dampers appeared to be almost closed.

Log: AHU-03/SPP-01 12/26/2024 Clint Walker The last “Final Filter” is the filter box located on the roof outside of the penthouse. I did not see anyway to access this as it is all insulated. I utilized an existing hole that had been drilled on the discharge side of the filter section.

AHU-03/SPP-01 12/26/2024 Clint Walker The pressure drop across the heating coil actually represents the drop across the heating coil and the cooling coil as they are located back to back.

AHU-03/SPP-01 12/26/2024 Clint Walker There are some final filters missing from the final filter section. I have to assume the pressure differential would have been higher if they are all in place. I have included a picture in the deficiencies section of this report.

ICU AHU Outside Air Audit Notes

1. The design team requested that I try and determine the amount of outside air for the AHU that serves the ICU. A velocity matrix was performed at the outside air inlet. The results are as follows:

2. The outside air damper was opened approximately 10%. The return air damper was opened approximately 90%. The exhaust air damper was 100% closed. Please see the attached picture.

3. The filters are dirty. Please see the attached picture.

9.1 ICU Re-Heat Pump-01

9.2 ICU Re-Heat Pump-02

ICU Re-Heat Pump Notes

1. There are two pumps that run at the same time at a constant speed.

2. Neither pump has ports installed that would allow me to take a suction or discharge reading. Ther are no gauges installed. There are only check valves and isolation valves installed.

3. ICU Re-Heat Pump #1 is a Gurndfos pump. I was able to input the nameplate information into the website. I am attaching that as well as pictures of the nameplate data immediately following this notes section.

4. ICU Re-Heat Pump #2 is a Bell & Gossett pump. It is a Series 60 pump. These pumps have been replaced by the eSeries 60 pumps according to their website. I was able to use older pump parts lists and motor parts list to get some of the missing information from the name plate data. It appears that this pump was a generic Series 60 pump as the GPM, Feet of Head and impeller data was not stamped on the pump nameplate. I am attaching the pages I used as well as a picture of the motor and pump name plates. The J59 identifier in the Part #M80067 J59 identifies the production date of this pump as September of 1995.
