FACILITY HVAC.



Introduction to Facility HVAC.

Where facility HVAC environmental conditions, such as temperature, humidity, particle content and biological contamination are important aspects of pharmaceutical, biotechnical and or medical device production, validation and qualification of the HVAC system must be performed.

This HVAC Facility validation must utilize a risk-based approach, which involves a high level of process understanding and focuses on potential problems, risks, and all suitable countermeasures. The facility HVAC validation must verify that in all areas where drugs or raw materials have air contact, the air cannot adversely affect the quality or efficacy of the product.

To fulfill regulatory requirements, a clean room HVAC system must maintain environmental condition within specified specifications. These conditions must be regularly monitored to ensure constant awareness of environmental conditions, such as temperature, humidity, pressure and particle levels. Digital outputs for alarms must also be monitored to ensure that an alarm will be raised if there is a change in any of the designated parameters.

All such environmentally controlled areas, zones and or rooms must be included in a preventative maintenance and calibration program that will monitor all trends and ensure continued use within the User Requirements specified specifications.


Energy Requirements and Efficiencies.

This graphic depicts the relationship between weight of water in Facility HVAC validation.

Two essential requirements for comfortable and healthy indoor environments are adequate ventilation and good humidity control. Unfortunately in humid climates, which includes much of the densely populated regions of the world, it is difficult to meet both these requirements without using a lot of electricity.

The fundamental problem is that a conventional cooling coil (whether using chilled water or direct-expansion refrigerant) cannot effectively meet the latent loads from ventilation on very humid days. All conventional chillers and air conditioners are essentially sensible cooling devices that dehumidify by lowering air temperature below its dewpoint so that moisture condenses. These systems must run with a wet cooling coil and the air that leaves this coil must be close to saturation.

The limitation of conventional chillers and direct-expansion (DX) air conditioners becomes evident when one tries to use them in an advanced HVAC system. Technologies such as displacement ventilation, chilled beams, and radiate panels can be part of a low-energy HVAC system that eliminates the fan energy used in a conventional system that recirculates large volumes of air.   However, these advanced systems will not work with a conventional chiller or DX air conditioner that supplies relatively cold air (e.g., 50 to 55 F) that is saturated with moisture (i.e., 100% rh). What is required is a cooling system that supplies drier, but warmer air.

Typical supply air conditions for displacement ventilation are 65 F and 50% relative humidity. This supply air has an absolute humidity of 45.5 grains moisture per pound of dry air (which is equivalent to a humidity ratio of 65 g/kg and a dewpoint of 46.0 F). Any cooling system that dehumidifies air by reducing its temperature to condense the moisture must first cool air to below 46 F and then reheat the air to 65 F. As shown on the neighbouring psychometric chart, a cooling system that process 6,000 cfm of warm, humid outdoor air must do 54.0 tons of cooling and then 10.8 tons of reheating. This air conditioner is doing 25% more cooling than is required to meet the load.   Furthermore, this percent excess cooling becomes much larger during cooler, damp weather, e.g., if it were 70 F and raining, overcooling would be 42% of the required cooling.

This cycle is seldom understood by management, who consequently fail to realise that the rise in energy consumption of a system 'out of calibration' can be very substantial.  These systems should be subjected to annual calibration and a defined method of tuning to attain minimum energy consumption.

Validation Risk Assessment (Issue-11.)  $125.00
10000014

The Risk and Part 11 Validation Risk Assessment(VRA) protocol is becoming the most important document in the validation train. The VRA reassures the regulators that you have looked at specific equipment functionality and considered the appropriate level of validation that is required. You have also considered various aspects of its use and the implications of any malfunctions. From the results of this exercise the scope of all validation activity can and must be justified. This is a robust and simple to execute document, one that will lead you through the process and deliver a result that can be used as the foundation for your validation activities.
This VRA now includes the assessment table for categorising and documenting the new 21 CFR Part 11 guidance ruling on what predicate data must be stored in a Part compliant system, along with the new broadsheet to establish your new database of part 11 records. (now mandatory).

Cold Chain Zone PQ (Issue 4)
$89.00  10000408

The Performance Qualification is the last of the qualifying tests that equipment and processes are subjected to, prior to the actual first product run. It maybe that there are some steps in the process that can only be verified by actually running them (quick freezing and sublimation, to mention only two) or it somtimes is the fact that the product is a very expensive product, and can not be wasted. So no one wants to run the process with product, until they are completely certain there will be minimal waste.
