Heating Ventilation and Air Conditioning systems (HVAC) systems are fundamental to the operation and control of laboratories in particular where barriers and containment systems are in use.
Getting the balance right is a crucial factor for all laboratories but especially for facilities with containment and barriers. In addition, clean rooms and aseptic facilities require carefully balanced rooms with demonstrable test results that meet with regulatory compliance.
Following on from the BPO process
The recommissioning specification must identify the systems to be recommissioned, their functions, duration of operation and interrelationship with other plant and systems.
Drawings, schematics and design data should be available. These should show the locations of the following:
A commissioning programme is generally agreed which will enable the rebalance to be achieved whilst the facility is operational.
Access for areas must be determined and PPE requirements established. Together with knowledge of any restrictions between areas within the facility which must be clearly understood prior to the start of the process (restrictions across the barrier in a BSU for example).
The commissioning process that CCTech implement is always predicated on meeting the requirements of the relevant codes of practice, guidelines and regulatory compliance.
Key to the success of any rebalance is an agreed programme with the end users, this will include the following:
The commissioning programme will generally require the resetting of all fixed and dynamic dampers across a full system – access to dampers must be determined in advance to ensure a smooth programme of works.
Once the rebalance of the facility is completed the readings are reviewed and witnessing commences with an independent expert appointed by the client to verify the readings are achieving the required settings.
A full and complete set of commissioning check sheets and test record sheets are provided to the client by CCTech. CCTech will update all drawings and schematics to reflect the new operating levels.
Seasonal commissioning may be required.
Occupancy Evaluation will be required at regular intervals for the first year.
