We all are familiar with heating and cooling systems. Most of us. We knew that our home stayed warm due to our heater and stayed cool in the summer because of our air conditioner. We also knew that if we adjusted the plastic box on the wall called a thermostat that we could make our home warmer or cooler. This probably all sounds a bit obvious and pointless to mention, but we do mention this because of how common HVAC systems are, but yet how little the everyday person knows about them.

H Stands For Heating
The way a building is heated is determined not only by its age but by its type. A building can be heated by various types of commercial HVAC systems, including supply air systems, perimeter fin-tube radiators or by floor, ceiling, or wall radiation.

V is For Ventilation
Having a healthy ventilation system as part of your commercial HVAC system is vital for many reasons. For building occupants to be able to not only be comfortable but also healthy, there must be a healthy mixture of breathable gases in the air. Also, ventilation systems rid the air of odors, allergens, germs and other contaminants that are frequently found in the air around public spaces and contribute to company-wide illness and allergy issues. There is such a thing as having a “polluted building” because your commercial HVAC system is inadequate for your building’s size or needs, or is not receiving proper maintenance.

A Stands for Air Conditioning

Air conditioning is referred to in the HVAC industry as sensible and latent cooling of air. Sensible cooling refers to the control of the actual heat of the air, and latent cooling involves the thickness of the cooled air. Having both tangible and latent cooling is important because cool, humid air is, for most, very hard. For climates that are dry, adding moisture to the air is important as well. There are several means for cooling the air: water loop heat pump system, air-cooled or water-cooled equipment, and geothermal exchange.

C is for Control

The controls of an HVAC system allow for keeping a building’s residents comfortable while also efficiently using energy resources. These controls also regulate how hard a system has to run to meet the demands of the building. Most commercial HVAC systems are made to handle more than they would ever probably need to.
