Industrial HVAC System how the air conditioning works in these environments
The acronym HVAC: Heating, Ventilating and Air Conditioning, which in Portuguese was translated to: HVAC - Heating, Ventilation and Air Conditioning, refers to the basic and primordial functions of air conditioning systems.
There are 3 core functions of HVAC. Together they make up a system responsible for ensuring thermal comfort to users of the environments, high air quality, in addition to enabling control over some variables related to the air.
The inclusion of the “R”, as the 4th acronym: HVAC-R or AVAC-R, refers to the Refrigeration function.
In this way the acronym becomes a little larger, and the system more comprehensive and complete.
HVAC
Understanding what each of the acronyms means separately, without a doubt, helps to understand a little more about the functions of the system as a whole, see:
A or H - It concerns the function of heating responsible for keeping the air temperature stable on cold days. This function corrects low temperatures, bringing greater comfort to people in these climatic conditions. Also used for maintaining the maximum relative humidity of the air (air reheating).
V - A ventilation it fulfills the role of oxygen renewal and promotes air circulation, removing odors and impurities from it, in addition to preventing, for example, gases such as CO² from increasing their concentration in environments.
AC - The system air conditioning controls the temperature and promotes ventilation and cooling of the environment. In addition, it is in the air conditioning equipment that the air filters. These carry out the removal of impurities and air contaminants harmful to health.
R - A REFRIGERAÇAO removes heat from the environment by controlling and maintaining the low temperature, artificially cooling the air. Certainly essential in some applications such as food industries and refrigerators, where the low temperature guarantees food preservation. In addition, it is worth remembering that this system is part of one of the Air Conditioning functions.
Industrial HVAC System How Exactly It Works
The combination of all these functions in a single system promotes air stability in places that need extreme control of all the variables that are linked to the air, such as in clean rooms and pharmaceutical industries, which are critical environments that require high air quality (current regulations were created to establish strict parameters regarding the level of air temperature, humidity and count of suspended particles in these environments).
HVAC equipment meets all these requirements accurately and safely, providing air renewal and air conditioning.
Mainly used in industries (of different branches), as well as in shopping malls, offices, buildings and even homes, the HVAC system provides:
- air filtration
- Renewal of ambient air
- Retention of dust particles
- Minimization of fungi and bacteria
- Thermal comfort
- Decreased cases of allergic and respiratory diseases
Air Filters
In turn, the air filters that act within the HVAC systems perform the role of removing dust particles, mites, fungi and bacteria from the air that are harmful to the people who live in the place.
Changing the filters and maintaining the HVAC system are essential to guarantee the efficiency of this system, avoiding the uninterrupted operation of the equipment's refrigeration system, which would cause an increase in electricity consumption (increase in the electricity bill), failures in the system and even stop or break.
