The meaning of the acronym HVAC is Heating, Ventilating, and Air Conditioning. But what uses and applications do these systems have?
What Is An HVAC Ventilation System?
An HVAC system is used to renew and treat the air within an environment in order to provide it with humidity, temperature, and health conditions (improving its purity and conditioning it to achieve air suitable for breathing) that are comfortable for people.
How Does An HVAC System Work?
The operation of the HVAC is as follows:
The system contains a gas that, when subjected to pressure, is compressed and its temperature increases, thus heating the duct through which it runs and giving off heat. The subsequent cooling occurs slowly and then, the remaining liquid is expelled in the form of gas through ventilation grills. In the passage from the gaseous state inside until the expulsion, it absorbs the internal or external heat of the environment. This process works without interruption if the system is activated.
HVAC Systems Applications
The uses of an HVAC system are different, depending on the type of unit we are talking about. The environment in which it is installed and the activities carried out there determine both the type of system and the actions it performs.
The actions that an HVAC performs are:
- Air heating
- Ventilation for air renewal
- Air cooling
- Indoor air movement
- Distributing fresh air from outside without drafts
- Humidification/dehumidification of the environment
- Filtering the air to remove dust, fumes, and all kinds of solid particles suspended in the air.
HVAC In Hospitals
HVAC systems play a very important role in hospitals. They are responsible for maintaining comfortable climatic conditions through humidity and temperature control and maintaining a clean, germ-free environment. Its presence is relevant due to its ability to increase the comfort of patients and medical teams while reducing the risk of spreading diseases. As these are particularly critical environments, the design of HVAC systems in hospitals acquires special importance.
Pharmaceutical Industry HVAC Systems
When we talk about the pharmaceutical industry, there are strict regulations regarding the conditions of the work area and the performance of the air equipment. The sector is obliged to comply with specific thermal parameters in manufacturing, packing, distribution, and storage. This is because the raw materials of its compounds, such as microorganisms or biomolecules, are very sensitive to fluctuations in temperature and air humidity. The control of both environmental factors is crucial to ensure the success of operations with pharmacological products. These air treatment systems for the pharmaceutical industry are not only applied for the protection of the product but also for the protection of personnel. Through its use, safe air is guaranteed for the equipment that operates in R&D laboratories and in the production area.
