TEMPERATURE & RELATIVE HUMIDITY MONITORING

TEMPERATURE & RELATIVE HUMIDITY MONITORING

Objective:

To demonstrate the capability of AHU to maintain room temperature and relative humidity within the specified design limits.

Acceptance Criteria:

The room temperature and relative humidity shall meet the design values as set for each room.

Test equipment:

Thermo-hygrometers.

Procedure:

1.      Before starting the study ensure that Air conditioning system is in continuous operation for at least 24 hour prior to performing these tests.
2.      In the area the temperature control zone shall be divided into grids of equal area having dimensions of approximately 100 ft²(3m. X 3m. or 9m²). If the area is less than 100 ft²(3m. X 3m. or 9m²) temperature  mapping shall be done at one location.
3.      In small area the temperature monitoring shall be done at single location. If the huge area it can be increased instead of 1 location.
4.      If the storage racks are provided in the area, the number of locations shall be distributed at top, middle and bottom level of racks. No. of temperature locations can be increased as per study requirement .
5.      Monitoring area with no. of locations to be monitored.
6.      Ensure that the measuring instrument is in calibrated state with a valid calibration certificate.
7.      Distribution studies shall be performed at working height level. Monitor the temperature and relative humidity in all critical rooms, area for 3 days with an interval of 30 minutes for mapping with data loggers.
8.      Manually monitor the temperature and relative humidity in all non-critical rooms area for 3 consecutive days considering 3 times a day(During working shifts) with a frequency of 4 hours.

Dr Reddy's board gives nod to induct third generation leadership into the company: Dr Reddy's Laboratories board has given green signal to induct Akhil Ravi, the son-in-law of GV Prasad, Co-Chairman, and CEO - of Dr Reddy's into the company management. Drug maker Dr Reddy’s Laboratories board has given green signal to induct Akhil Ravi, son-in-law of GV Prasad, co-Chairman and CEO of the company into the management. The decision was taken at the company's board meeting in October and was notified on Wednesday. Akhil Ravi represents the third generation of family leadership of Dr.Reddy's, founded by late K Anji Reddy. The company is now jointly run by Anji Reddy's son-in-law GV Prasad and son Satish Reddy, 50. The promoters hold 27.66 percent stake in the company. The drug maker ended with sales of little over Rs 14,000 crore in FY17. Akhil Ravi, who will be joining the company in a mid-senior management role as Director of Business Development a...

AIR VELOCITY MEASUREMENT

Image
AIR VELOCITY MEASUREMENT Purpose: To provide a procedure to measure for airflow velocity and uniformity of velocity and supply airflow rate in clean room and clean zone. Scope: Applicable to all Air Handling Units system, Forced Air Ventilation system, Laminar Air Flow system(Unidirectional airflow system), Dynamic pass boxes, Garment Cubicles, Air showers, Air duct, Non unidirectional airflow installation(Diffuser, Grills, Risers). Responsibility: All HVAC Engineers. Definition: Uniformity of air flow: Unidirectional air flow pattern in which the point-to-point readings of velocities are within the defined percentage of the average airflow velocity. Unidirectional airflow: Controlled air flow through entire cross section of clean zone with steady velocity and approximately parallel streamlines. Non-Unidirectional airflow: Air distribution where the supply air entering the clean zone mixes with the internal air by means of induction. Laminar A...
