Each Packaged type air conditioning unit (PACU) is equipped with supply air (MVD), Return/Re-circulated air (MVD) along with Outdoor air (VD) Damper. Separate ducting from each Unit of the pair combines into one common ducting (sized for 100% of Supply air from single Unit). The supply air is ducted while the return air is free. The volume damper for supply air is motorized while the other volume dampers are manually operated. The duct smoke detector is mounted on the common supply & return air duct. The Fresh Air or Outdoor Air is supplied through the Sand Trap Louver with Wire Mesh Screen & Aluminum filter. The Fresh Air intake from the Sand Trap Louver arrangement is connected to the openings provided in PACU unit. If the PACU Unit is not running i.e. in standby mode, then all the Motorized volume control dampers (MVD) is in closed position. For the Duty Unit, the Supply Dampers (MVD) is fully opened; while Return Air damper (MVD) is also operating respectively and Outdoor Air Damper (MVD) is set at minimum open position. The minimum open position for Outdoor Air Damper is that which provides the minimum Flow Rate of Outdoor Air required for ventilation and pressurization of zones and maintains a +ve pressure of 0.2” of W.G. The Duty & standby units will operate on a shift basis. The changeover from duty to standby unit or vice-versa can be either automatic or manual. In “Automatic” mode, the Changeover from duty to Standby unit is either on the Time Basis or due to failure of running unit. The time Basis changeover can be set from one day to one week, as required. The 7-day per week – 24 hour per day timer shall take care of scheduling the operation of the two units in order to make sure that the two Units works equally. Also in case of failure of the running PACU unit due to any reason, then the operation shall be transferred automatically to the standby PACU unit. “Manually” the changeover can be activated any time from the HVAC Control Panel. The temperature controller (or Thermostat) will decide whether cooling or heating is required or not, by comparing the set-point with actual space temperature, If cooling is required then DX cooling stages have to be activated/deactivated based on the cooling demand to meet the set-point, which is adjustable from the controller display. If heating is required then the duct mounted electric heater is activated. The Temperature controls shall be provided as part of the AC unit by the Control Panel Supplier/Installer. The Thermostat shall be cooling and heating type with a minimum of 2 stages of Mechanical Cooling / Heating. The Thermostat shall be mounted on the return air stream @ 1.5M above F.F.L. The Thermostat shall be provided with lockable transparent cover.

In case the Smoke Detector installed at the common Supply and Return air Ducts detects smoke or the FACP sends a signal indicating smoke presence, then the Duty Packaged unit shall be automatically de-energized and all temperature control function shall stop. At such condition, an indication shall be sent to the HVAC control Panel also. During the Smoke purge operation all PACU’s (Duty and standby) dampers (Supply and Return air) will be closed and smoke purge / exhaust damper and Return Opening MF/SD will be opened fully to clear the smoke and product of combustion from the concerned zone. Smoke Purge Fan operates during smoke purging operation i.e. to exhaust smoke from the zones in the event of fire or heavy smoke conditions. It should be possible to manually run the Smoke Purge Fan either from the HVAC Control Panel or from Smoke Purge Fan isolating switch or from Remote Selector Switch located outside near the main door of Control Room. After the smoke purging operation ends, it would only be possible to re-start the Air Conditioning units by re-setting the HVAC Control Panel. Also smoke purging fan shall not operate unless PACU is de-energized.

As per TES-K-100.01 P-51 of 89 (sec. 10-1-b) in substations, control room and other duct sensitive facility, it is mandatory to provide 10% of supply air fresh air make up. Therefore 10% of the supply air for the fresh air make up is 4,927 CFM (For supply air quantity Refer cooling Load (CHVAC) Output sheets; section: C)

2.

As per TES-K-100.00 P-51 of 89 (sec. 10.2) the maximum amount of outside air shall equal the greater of 5% of supply air in excess of all exhaust air. Therefore 5% of total supply air is 2,464 CFM plus exhaust and ex-filtration air, i.e. 2,464 + 0 + 165 CFM. Total makeup air is 2,629 CFM.

The load calculations is performed using HVAC software (Elite CHVAC SOFTWARE Ver. 7.01 (window based) commercial HVAC Program) which employees ASHRAE CLTD / CLF calculation’s method / guidelines. For calculating the Sub station’s cooling and heating load, the building is divided into separate zone, keeping in view its orientation, purpose and load profiles. The load inputs (i.e. area, orientation, occupancy, equipment and light load etc.) are described in the “Zone Wise Data Sheets”. The Calculation was performed using the above data on proportion supply CFM basis. The load summary is given below. Detailed computer load output is attached.

AIR CONDITIONING DUCT SIZING:

REVISIONS

The supply air and return / exhaust air ducting for HVAC system is designed by using the “Equal friction method”. Velocity and friction rates are adopted from SEC Standard for low velocity system. (Refer attachment: “G-1”; SEC Engineering standard - TES-K-100.01). As per this standard, duct velocity ranges for low velocity system are as follows; INDUSTRIAL BUILDING

MAIN DUCT Supply Duct Velocity

1200 – 1800 FPM

Return Duct Velocity

900 – 1400 FPM INDUSTRIAL BUILDING

BRANCH DUCT Supply Duct Velocity

800 – 1000 FPM

Return Duct Velocity

600 – 800 FPM

For sizing duct, from above velocity range, we select a velocity, so that the friction drop is kept constant at around 0.05” to 0.15” of W.G. per 100 ft of duct run for main Supply & Return ducts. This friction rate is kept constant for sizing the remaining main and branch ducting. Sample Duct sizing calculation for the supply and return ducts, using ASHRAE tables is tabulated below.

DIFFUSER / GRILLE SELECTION: The Supply & Return Air Grilles and Diffusers are selected on the basis of Noise Criteria. In our case for diffuser / grille selection we chose such an air outlet terminal which gave Noise Criteria between NC 20 – NC 40, and keeping other factors like throw, terminal velocity within reasonable range. The Noise Criteria adopted is well within the recommended range for Industrial Areas, which is between NC 40 – NC 50 ( Refer ARAMCO Standard # AES-A105 - Attachment: “G-4”). Also adopted range is as per the SEC specifications (TES-K-100; Ref. Attachment: “G-5”) A summary for the selected Diffusers / Grilles for different zones are given below; ZONE DATA

Description "Loss" = Static pressure loss through the indicated fitting. "Equip" = User-entered loss through central equipment (supply main trunk only). "Add.L" = User entered additional static pressure loss. "F.Tot" = Total of all the fitting static pressure losses. For supply main trunk, also includes loss through central equipment and any loss carried from return system.
