APPLICATIONS OF HVAC IN COMFORT, PHARMACEUTICAL AND CLEANROOM
HVAC is playing an enormous role in the world market. It is basically a system which keeps the other sector work more efficiently and impacts positively to a world market. Today we are going to understand the important application of HVAC in comfort, pharmaceutical and cleanroom.
Application of HVAC has enrolled in a big space in the world market. Application of HVAC in comfort, pharmaceutical and cleanroom has a tremendous impact on world efficiency and effectiveness.
So let's dig into the different application which is very important in the sector mentioned so let's start a kickoff to the application of HVAC in comfort, pharmaceutical cleanroom industries.
COMFORT APPLICATIONS IN HVAC
Air conditioning is the process of removing heat and moisture from the interior of an occupied space, to improve the comfort of occupants.
Electric refrigerant-based AC units range from small units that can cool a small bedroom, which can be carried by a single adult, to massive units installed on the roof of office towers that can cool an entire building.
The cooling is typically achieved through a refrigeration cycle, but sometimes evaporation or free cooling is used. Air conditioning systems can also be made based on desiccants (chemicals which remove moisture from the air) and subterraneous pipes that can distribute the heated refrigerant to the ground for cooling In the most general sense, air conditioning can refer to any form of technology that modifies the condition of air (heating, (de-)humidification, cooling, cleaning, ventilation, or air movement).
In common usage, though, "air conditioning" refers to systems which cool air. In construction, a complete system of heating, ventilation, and air conditioning is referred to as HVAC.
HVAC FOR PHARMACEUTICAL INDUSTRIES
All pharmaceutical industry products must be produced in air-conditioned and clean space, for this reason, the air conditioning and ventilation system in the pharmaceutical the industry is one of the most vital elements in the manufacturing process.
In pharmaceutical manufacturing, how space conditions impact the product being made is of primary importance. The pharmaceutical facilities or industries require to conform to CGMP (Current Good Manufacturing Practices).
These regulations, which have the force of law, require that manufacturers, processors, and packagers of drugs to take proactive steps to ensure that their products are safe, pure, and effective, GMP regulations require a quality approach to manufacturing, enabling companies to minimize or eliminate instances of contamination, mix-ups, and errors.
HVAC system performs four basic functions:
1. Control airborne particles, dust and micro-organisms - Thru air filtration using high-efficiency particulate air (HEPA) filters.
2. Maintain room pressure (delta P) - Areas that must remain cleaner" than the surrounding areas must be kept under "positive" pressurization, meaning that airflow must be from the “cleaner" area towards the adjoining space (through doors or other openings) to reduce the chance of airborne contamination. This is achieved by the HVAC system providing more air into the "cleaner" space than is mechanically removed from that same space,
3. Maintain space moisture (Relative Humidity) - Humidity is controlled by cooling air to dew point temperatures or by using desiccant dehumidifiers. Humidity can affect drugs and is sometimes important to effectively mould the tablets.
4. Maintain space temperature - Temperature can affect production directly or indirectly by fostering the growth of microbial contaminants on workers.
HVAC FOR CLEANROOM
A cleanroom is a room or space in which the level of particulate contamination is controlled within set levels. The construction, temperature, humidity, airflow patterns and pressure are controlled in such a way as to minimize the introduction, generation and retention of particles (such as dust) inside the room. These rooms are used commonly within the scientific research, medical, pharmaceutical and high technology manufacturing industries, where product/sample quality and employee wellbeing are critical Cleanroom Classification:
Cleanrooms are classified from ISO 1 to ISO 9. These standards are based on the number of particles allowed per unit volume of air within the space. The physical size of a particle is measured in a unit called known as a micron (um). To put the size of a micron into perspective, a human hair is approximately 75 microns in width. A typical room in a home would contain more than 10,000,0000 particles of 0.5 um and above, this roughly equates to a class ISO 9 cleanroom.
This is most important application in HVAC, which plays a vital role to process the industry smoothly without any page break.
