The Time Is Running Out! Think About These Ways To Change Your Hvac-supplies
The acronym HVAC is Heating, Ventilating and Air Conditioning, which in Portuguese was translated to: HVAC – Heating, Ventilation and Air Conditioning, refers to the basic and essential functions of air conditioning systems.
There are 3 central functions of the HVAC. Together they make up a system responsible for ensuring thermal comfort to users of the environments, high indoor air quality, in addition to allowing control over some variables related to the air. You can search on blackhawksupply.com regarding the same.
The inclusion of “R”, as the 4th acronym: HVAC-R or AVAC-R, refers to the Refrigeration function.
In this way the acronym becomes slightly larger, and the system broader and more complete.
Understanding what each of the acronyms means separately, undoubtedly helps to understand a little more the functions of the system as a whole, see:
A or H – Refers to the heating function 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 to maintain maximum relative air humidity (air reheat).
V – The ventilation plays the role of renewal of oxygen and promotes air circulation, removing the same smells and dirt, and prevent for example gases such as CO² increase their concentration in the environment.
AC – The air conditioning system controls the temperature and promotes ventilation and cooling of the environment. In addition, it is in air conditioning equipment that air filters are usually inserted. These perform the removal of impurities and air contaminants harmful to health.
A – The coolant removes heat from the environment managing and maintaining low temperature, cooling the air artificially. Certainly essential in some applications such as the food and refrigerator industries, 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.
