Re: PS 260Q HVAC Investigation, Terminal Calibration and Air Device Balance

of RTU-1+2 Systems

Facility: 40-20 100th street

Queens, NY 11368

Dear Mr. Russelli,

Airpath completed the airflow investigation, air terminal calibration and

confirmed airflow rates at those air devices served by RTU-1 and RTU-2 systems at PS 260Q

(renamed PS 307).

The two variable air flow systems were tested and balanced by another firm

prior to our arrival. The final test and balance report indicated that these two RTU's are

of limited flow capacity that does not match the total connected air flow requirement of

either unit. Many inconsistancies have been reported by the original test and balance firm,

and are supported by Airpath. Some of the major issues that have been uncovered are as

follows.

Issue #1 It was reported to Airpath by the SCA and Botto Mechanical that the original

RTU-1 unit was placed in the designated RTU-2 roof position, and vice versa.

It was originally thought that the two units are identical, except for the internal

return fans. Presently the unit in the RTU-2 position has the larger return fan,

and a class 2 supply fan, capable of speed, pressure, and power ratings up to

1,200 RPM, 5" wc total static pressure, and 30 HP, to achieve 26,000 CFM. The

unit placed in the RTU-1 position has the smaller return fan, and a class 1

supply fan limited to speed, pressure, and power rating of 984 RPM, 3.75" wc

total static pressure, and 20 HP to achieve approximately 24,000 CFM.

Issue #2 The total connected VAV and FPB load designated for RTU-1 and RTU-2 are:

north RTU-1 (19,800 CFM from Mammoth submittal) 29,270 CFM connected

south RTU-2 (21,400 CFM from Mammoth submittal) 24,620 CFM connected

Obviously, the units do not match the system requirements, but the unit in the

RTU-2 position (south side of building) is currently satisfying the connected

terminals. The unit in the RTU-1 position (north side of building) is unable to

satisfy the connected terminals.

There are several other issues that may be addressed before the systems will achieve

improved air flow. These issues, as well as our observations are listed below:

OBSERVATIONS

1

heating mode, the damper shall close directing all air flow around the gas heat

tube. For testing purposes, Airpath repositioned the existing baffle to improve

the airflow capability of the unit. (see figures 1, 2, and 3 for configurations)

2 The supply air ductwork for RTU-1 has a soundtrap installed on the 5th floor

right before the system branches out into the four risers that distribute the

air to the connected terminals. The positioning of this soundtrap severely

limits the capabilities of the system. The static pressure drop across the

soundtrap is 0.4" wc to one branch and 1.1" wc to the other branch. The static

pressure at the discharge of the unit is only 1.5" wc.

The contract drawings do not identify a soundtrap, but specifies duct liner.

Airpath suggests that this soundtrap be removed in order to eliminate the

unnecessary duct air friction, which was not calculated into the fan total static

pressure selection. (Refer to Blue Diamond SM 5-3)

3 The fan classes for the RTU supply fans are not the same, RTU-1 was originally

specified to use a class 2 fan, however, the air handlers were swapped during

placement on the roof. RTU-1 now has the class 1 fan that was intended for

RTU-2. The fan class is important because the designation is based on its

operating range for maximum static pressure and rotational speed. The fan

which is now is RTU-1 is at the maximum limit of its class 1 designation.

In order to achieve design flow, the fan and motor would need to be upgraded

to a class 2 fan and a 30 HP motor. This is impractical to do at this time.

The discharge static pressure and total air flow of the unit can be improved

using the suggestions previously mentioned, but the required airflow for

full cooling will not be reached with the fan and motor currently installed.

Page 1.4

section creates a large restriction to air flow and a high drop in static pressure.

The design value of the static pressure drop is 0.19" wc, however, the static

pressure drop measured by Airpath on RTU-1 was 0.88" wc. This high pressure

controlled open in all non-heating modes, and when the unit changes over to

drop (due to air friction) has not been calculated into the fan total static

pressure and fan selection. Less fan energy and discharge static pressure is

available to the air terminals. Additionally, the way the baffle is currently

configured does not provide optimal heat transfer in the gas heating section.

Airpath suggests replacing the existing baffle with a bypass damper that is

Airpath believes that the gas heat section of both rooftop units RTU-1 and

RTU-2 have an inherent high air friction loss, much greater than the published

submittal values. The sheet metal baffle that is installed in the gas heat

4 Airpath noticed that the brake horsepower specified in the contract drawing

equipment schedule for the return fans of both RTU-1 and RTU-2 exceed the

size of the motor specified. This seems to have been corrected in the Mammoth

submittal data, the equipment currently installed matches these corrections.

5 The following terminals were unable to achieve design flow due to low pressure

in the supply ductwork in riser 4 on RTU-1:

FPB-108, FPB-212, FPB-312, FPB-410, FPB-506, FPB-508, FPB-510

Airpath believes that resolving the issues previously mentioned concerning the

duct static pressure will allow these boxes to achieve the required air flow.

6 Airpath found volume dampers installed on the FP-VAV inlet ductwork on the

second floor. These dampers were not fully open, and were restricting the

airflow to the terminals. The dampers are shown on the Blue Diamond shop

drawings, but not specified in the contract drawings. Airpath fully opened

each of these dampers to allow the air to pass freely. ( Normally, dampers are

not installed upstream of FPBs or VAVs)

7 The terminals listed below do not function correctly and are in need of repair:

-FPB 207 on RTU-1 cannot achieve maximum design flow. There is insufficient

static pressure upstream of the terminal.

-The fan speed control knobs on FPB-206 are broken off and cannot be adjusted,

currently the actual fan flow is 300 CFM above the design rate of 900 CFM.

-FPB-305 on RTU-1 has a malfunctioning fan motor controller, the fan is not

currently running.

-FPB-308 on RTU-1 is not communicating properly with the BMS. The flow

setpoint is stuck at 0 CFM and does not change.

-FPB-505 on RTU-1 has a malfunctioning fan speed controller, the fan speed

cannot be adjusted. The fan is currently at low speed.

-FPB-414 on RTU-2 is unable to achieve the minimum design flow when the

damper is fully closed. Airpath verified the actuator is fully closed, but is not

seating closed.

-The fan motor in FPB-507 does not energize, this is possibly a fan controller

malfunction.

Page 1.5

SUGGESTIONS

1 Repair malfunctioning air terminals listed in the observations.

2 Implement an approved bypass damper modification in the gas heat section

of RTU-1 and RTU-2 to reduce excessive internal static pressure component

friction loss.

3 Remove the sound trap core located on the 5th floor RTU-1 discharge duct,

and reline the raw duct section. To reduce excessive external static pressure

discharge duct loss.

4 Since an increase in the fan speed to the unit in the RTU-1 position may not be

practical, Airpath suggests isolating one of the four risers (riser 4) and

connecting the riser to a smaller RTU with a total fan capacity of 7450 CFM

at 2" wc external static pressure.

If you have any questions regarding the information in the report, please do
