2.6.2 LIST OF EQUIPMENTS The list shown below includes the equipment that will be tested and balanced by Evolution. Double Regulating Valves (DRV). Pressure independent control valve (PICV).
2.6.3 TESTING AND BALANCING PROCEDURES After the check list is completed and checked, the testing & balancing stage will start according to the following procedures:
2.6.3.1. WATER FLOW REGULATION PROCEDURE (Fixed and variable Orifice) 2.6.3.1.1. WITHOUT BRANCH CIRCUITS: 1. Verify that all balancing, control, and isolation valves are wide open. 2. Determine total system volume by the most appropriate method. 3. Calculate the percentage of actual hydronic flow to design hydronic flow requirements. 4. Adjust the riser to approximately 110% of design flow, if possible. 5. Measure the differential pressure across each balancing valves to indicate the flow rate, by using the following equation
6. Starting at the riser, as the terminal units’ closets to the pump will typically be the highest, adjust the balancing valves to a value approximately 10% below design flow requirements. 7. As the adjustments proceeds to the end of the system the remaining terminal flow values will increase. 8. Repeat the adjustment passes through the system until all terminal units are within + or – 10% of design flow requirements and at least one balancing valve is wide open. 9. If necessary, adjust the riser volume to set all terminals at design flow + / – 10%. 10. Re-measure all terminal units and record final values. 11. Mark or set all memory stops on all of the balancing valves so that the adjustment may be restored if necessary. 2.6.3.1.2 WITH BRANCH BALANCING VALVES: 1. Follow above steps 1) through 5) above for the terminal units on each branch. 2. Compute the ratio of measured branch flow to design branch flow. 3. Starting at riser, as the branches closets to the pump will typically be the highest, adjust the balancing valves to a value approximately 10% below design flow requirements. 4. As the adjustments proceeds to the end of the system the remaining branch flow values will increase. 5. If necessary, adjust the riser volume to set all branches at design flow + / – 10%. 6. Balance the terminal units on each branch as described in above steps. 7. Re-measure all terminal units and record final values. 8. Mark or set all memory stops on all of the balancing valves so that the adjustment may be restored if necessary. 2.6.3.2. SELF-ADJUSTING VALVE PROCEDURE (Automatic Balancing Valves): 1. Verify that all control and isolation valves are wide open. 2. Verify that all bypass valves fully close. 3. Verify that all PICV’s are adjusted to the correct Pre-setting to meet the design
requirement by visual check according to pre-setting schedule. 4. Ensure all valve actuators, if fitted are driven to their fully open position 5. Set the pump to design speed setting, turn the pump off then back on again. 6. Measure the differential pressure across each PICV by Hydronic Differential Pressure device. 7. Verify that the measured differential pressure at each PICV is within the operational pressure range. 8. Check the flow rate of the branch orifice plate to verify its value is equal to the sum of the pre-set PICV flow rates fed from the branch (if exist), otherwise more investigation is needed to establish the reason, once corrected measure again and record final results onto test sheet 2.6.4 INSTRUMENTS During the water balancing process, many types of instruments will be used, all these instruments should be within the calibration dates, and the calibration certificate are not more than 12 months. All instruments which will be used in this project should have control sheets to check certification validity and periodic visual inspection to check they are free of damage. The following major instruments will be used but not limited to, during the testing and commissioning works: No. 1 2 3 4 5

General Measurements Procedures
The following procedures are general procedures and will be repeated for most type of the equipment: 2.6.1. Fan and motor testing (Applicable for all AHU's and Fans): It is very important to check the fan and motor -before starting the testing of the airflow- by checking the voltage, Rotation, RPM, TSP and the amperage of the fan and motor, and record all this data and measurements onto test sheet. To test the fan, follow these procedures: 1. Record the voltage and the Full load ampere from the motor nameplate. 2. Record the over load setting and range. 3. Turn on the fan, and measure the voltage and ampere by using multi meter; at the rated voltage and frequency the ampere demand (drawn) shall not exceed the manufacturers stated full-load ampere 4. Verify correct rotation of the fan. 5. Measure the RPM for fan and motor by using Tachometer, and compare to design RPM's. 6. Use the micro manometer to measure the static pressure for suction and discharge of the fan to calculate the fan total static pressure. 7. Use the micro manometer to measure the static pressure and calculate the external static pressure for the fan. 8. Record all data and measurements from points above onto test sheet. 2.6.2. Establish Fan total airflow (Applicable for all AHU's and Fans): The most accurate and accepted field test to establish the airflow is a Pitot tube traverse of the main Discharge duct if enough straight duct is available, the Pitot tube traverse in a duct is performed as follows: 1. Measure the external dimensions of the duct to be traversed. 2. Determine if the duct is internally insulated. 3. Make number of holes in the duct according to the duct size 4. Mark the Pitot tube at the correct points. And connect the tubing to the Pitot tube and manometer. Verify the "zero" of the instrument as required prior to inserting the Pitot tube into the duct.

5. Insert the tube into the duct. The tip of the Pitot tube shall point into the air stream, and be parallel with the direction of airflow. 6. Perform and record a measurement of air velocity at each required point. 7. Once the average duct velocity is determined, multiply the average velocity by the net cross-sectional duct area. The result is the total airflow volume. 8. Measure the static pressure inside the duct by using the Micro manometer. 9. Record all data and measurements from points above onto test sheet. 10. All drilled test holes to be bunged after test procedures have been completed. Where insulation has been removed this needs to be rectified. 11. In case of JET fans, the test will be at fan face, and if this was not applicable for any reason then contractor will create small duct extinction for testing purpose.
2.6.3. Constant Air system balancing procedures (Applicable for supply, exhaust & return duct networks): Note: Individual return grilles in open-ducted (Non-ducted grills or dummy Grills) return air systems cannot be balanced even if design return airflows are indicated on the plans, so there is no balancing will be done for non-ducted or dummy return inlets 2.6.3.1 without main branch ducts 1. Verify that all grills, registers and diffusers dampers are fully opened. 2. Verify that all dampers in the duct system are fully opened. 3. Determine total system air flow by Pitot tube traverse according to Point 2.6.2. 4. Calculate the percentage of actual air flow to design air flow. 5. Adjust the fan to approximately 110% of design airflow, if possible. Making sure that the maximum permissible fan motor current is not exceeded 6. Measure the air flow at all air outlets. 7. Compute the ratio of measured airflow to design airflow for each air outlet. 8. Starting with the air outlets that have a highest percentage, adjust the volume damper to the value approximately 10% below the design airflow requirements. 9. As the adjustment proceeds to the end of the system, the remaining outlets air flow values are supposed to increase. 10. Repeat the adjustment passes through the system until all air outlets are within +-10% of design airflow requirement and at least one outlet volume damper is wide open. 11. If necessary, adjust the fan speed to set all air outlets at design airflow, +-10%. 12. Re-measure the flow for all air outlets and record the final airflow values. 13. Mark all dampers with felt markers, spray paint, or other permanent technique, so that adjustment may be restored if necessary. 2.6.3.2 with main branch ducts Where a system has main branch ducts, the procedure is: 1. Follow above steps 1) through 6) for outlets on each branch. 2. Compute the ratio of measured branch flow to design branch flow. 3. Starting at the fan, as the branches closest to the fan will typically be the highest, adjust the branch volume dampers to a value approximately 10% below design airflow requirements.

4.0. Temperature and Relative Humidity Test Procedure 4.2.1 Introduction For temperature and relative humidity measurements to be meaningful and the data to be reported accurately, advance preparations must be completed. The NEBB Qualified Temperature Supervisor shall examine the contract documents, examine the approved equipment submittals, and inspect the equipment installation prior to taking any field measurements. This point cannot be overstressed. 4.2.2 Examination of Contract Documents The purpose of the Contract Document examination is to become familiar with the Project requirements and conditions that may preclude proper temperature and relative humidity testing. This information may be found in the Architectural or Mechanical Drawings or some other part of the Contract Documents. The specifications shall be examined for the following items: a. Design temperature and relative humidity for the different rooms. b. List of any rooms or spaces noted in the specifications that require special temperature and humidity. c. Description, approved manufacturers, etc., of the equipment. 4.2.3 Construction Readiness All mechanical/electrical systems should be started, operated and completely under functional control. Testing, adjusting and balancing activities shall be completed. Items such as painting, hard surfaces flooring, etc. is not required. 4.2.4 Temperature and Relative Humidity Measurements Procedures: A. Choose a suitable day, when the outside weather conditions are within the normal values. B. Run the unit that should be tested and make sure that compressors are running correctly. C. Take the dry bulb and wet bulb temperatures at the return and supply ducts. D. Take the outside dry bulb temperature and relative humidity. E. Close windows and doors to the space. F. Adjust the thermostat set point to be at the design temperature of the room. G. Once the room temperature comes around the set point temperature, take temperature and relative humidity measurements at the middle of the room. H. Repeat the test for the different rooms.
