Heating, Ventilation, and Air Conditioning is a system design of technology based on the mechanical engineering discipline and principles far beyond the understanding of us typical homeowner consumers. So let’s skip the technical mumbo-jumbo; this is not an engineering or physics classroom.
What is important to know is that it is all about developing an adequate system for your particular space (home, office, car) that will provide the most effective indoor environmental comfort. A product of the industrial revolution, HVAC systems are continuously reviewed and reworked, ever striving for greater effectiveness and energy efficiency.
The design of the HVAC system is critical because building conditions are regulated to provide us with fresh outdoor air that is safe and healthy. Simply put, it is a means of providing and removing air delivery from enclosed spaces.
While the terms “heating” and “air conditioning” appear to be self-explanatory in their definitions, primary health concerns can result from their operation without the coexistence of proper ventilation. It is easy to see that these three functions are interrelated. Ventilation is the process of circulating air within a building and exchanging it with outside air. An acceptable HVAC system should be designed to “maintain” indoor air quality, control temperature and humidity, and limit exposure to the health threats of airborne bacteria or carbon dioxide, while oxygen is replenished. Furthermore, potential air contaminants (such as smoke or dust) should be removed.
With continuous changes in technology, energy efficiency and government regulation, it is always best to contact your local HVAC expert when contemplating changing, replacing or installing a new heating and air conditioning system; your health and comfort may depend on them.
