Basics of HVAC
You have probably heard of the term HVAC. Have you ever wondered what it means?
HVAC is actually an acronym that stands for “Heating, Ventilation, and Air Conditioning” commonly pronounced as “H-V-A-C “ or “H-VAK”. The term itself is used for heating and air conditioning systems installed in homes, buildings and businesses throughout the world. Its primary use and purpose is to regulate room temperature, humidity levels, air flow and to maintain safe and healthy indoor conditions.
HVAC dates back as far as the second century, during Roman times, cities throughout the Roman Empire used a kind of central heating system (hypocaust). Commercially HVAC systems weren’t used until the Industrial Revolution, higher production rates and numbers of factories built increased the demand of HVAC systems needed. Nowadays HVAC systems are integrated in every aspect of our life, from our homes, to work, to stores, to hospitals, down to our cars use a kind of cooling system. HVAC has become an essential need of everyday life.
