HVAC stands for Heating, Ventilation, and Air Conditioning and is responsible for controlling the heat and air flow of a space. These can range from the air conditioner at home to the huge systems found in apartments, business establishments, office buildings, and industrial complexes. An efficient HVAC system provides indoor comfort by stabilizing thermal comfort. Its design follows the principles of thermodynamics, heat transfer, and fluid mechanics.
Components of an HVAC System
The ‘H’ in HVAC
Cool air is distributed via air conditioners and heat pumps. When the air conditioners and heat pumps are in the cooling mode, the heat is eliminated in the room and keeps the warm climate in your home during the cooler months of the year. These systems use refrigerants to cool the air inside a building and to remove excess humidity to provide air in a space.
This process is the same only in reverse for heating. There are several types of heating systems, with the forced air system as the most popular. However, many homeowners also use geothermal or radiant heating systems. All these systems create heat at a central source and distribute it throughout the home via different methods.
The ‘V’ in HVAC
Ventilation replaces the musty and stale air inside the building with fresh air. It eliminates some of the dust, heat, carbon dioxide, and moisture inside the area and replaces it with fresh outdoor air. It improves the air quality by removing the excess humidity inside a building, making it an effective humidifier.
The control component of an HVAC system, the thermostat controls the heat and air conditioning. It allows you to set the required temperature in a specific time for each room. It maintains the programmed temperature at the set time giving assurance that utmost comfort is inside your home. To regulate the temperature, you only need to press a button to attain your desired heating or cooling levels.
Different Kinds of HVACs
Keeping your home comfortable and livable is the main function of an HVAC system.
The Split HVAC System
This traditional type of HVAC has components that are fitted both in the internal and external area of your home or a building. They are optimized for the best heat and air flow. It includes a furnace, an air conditioner or a fan coil, an evaporator coil, and a heat pump system.
The Packaged HVAC System
These systems combine several components found in a single unit. Having a compact design, it is ideal for homes and building with no provision for the separate parts of a split HVAC system.
The Ductless Split HVAC System
This system is perfect for heating and cooling room additions or other areas, such as home theaters, garages, and exercise rooms, where installing or extending ductwork is not possible. It is a HVAC choice for homes with small spaces.
The Hybrid-Heat Split HVAC System
This system determines the external air temperature and chooses the fuel source that is the most economical for the condition. It includes both an electric heat pump and a gas furnace. It can also work to cool the air inside your home in spite of its name.
The Geothermal Heat HVAC System
These systems are the most cost- and energy-efficient systems available in the market today. They tap into the reliable and moderate temperatures of the earth to cool or heat your home.
