- OBJECTIVE:
To lay down a procedure for AHU Parameter monitoring.
- SCOPE:
This SOP is applicable for AHU Parameter monitoring at {Company Name} {Company Location}.
- RESPONSIBILITY:
- Technical Assistant – Engineering is responsible to perform the activity as per the SOP.
- Manager / Executive – Engineering shall ensure compliance as per SOP.
- ACCOUNTABILITY:
Engineering Head
Head Quality Assurance
- PROCEDURE:
- Switch ON the AHU as per the respective SOP.
- Measure the differential pressure across the filters (10, 5 & 0.3 microns) by using Calibrated digital manometer or magnehelic gauge.
- Whenever differential pressure of filters exceeds the specified alert limits, clean the filter as per the SOP
- After cleaning the filters ensure that clean filters differential pressure is within the limits and enter filter cleaning details in ‘Filter cleaning log’.
- Check the chilled water/hot water inlet and outlet pressure and check the functioning of modulating valves.
- If the inlet and outlet pressure difference is more than 1 kg/cm2, clean the strainer.
- Check the chilled water/hot water inlet and outlet temperature.
- Chilled water inlet temperature should be in the range of 5 – 9°C and outlet temperature should be in the range of 11 – 15°C. Hot water inlet temperature should be in the range of 40 – 60°C and outlet temperature should be in the range of 20 – 40°C.
- AHU Parameters shall be checked once in 15±3 days for all process areas and 30 ±1 day for all other Non process areas, and recorded in Annexure-I.
