Air Conditioning – NRG Heating and Air Conditioning
HVAC is an acronym for Heating Ventilation and Air Conditioning. Basic residential HVAC systems consist of 3 varying types:
The first kind, which is also the most common, is called the Split System:
-This HVAC system consists of an Air Conditioning Condenser (the unit sits outside, usually on the side or back of the home or on the roof), the Evaporator Coil, the Furnace, and the Air Duct System.
-The condenser compresses the refrigerant, transforming from a gas to a liquid state, and is then transferred to the Evaporator Coil.
-The air then passes over the Evaporator Coil, where it is cooled. The Furnace uses natural gas via burners located in the furnace to heat the home
-The Evaporator Coil is always situated with the Furnace, whether horizontally in the attic or installed as an upflow/downflow, which would be situated in a closet or the garage.
-As the air is sucked in by the Furnace through a return air grill, it then blows over the Evaporator Coil, which cools it, and then into the ducts, which blows the air into the home.
-The air travels throughout the home via a flexible polyurethane Air Duct System.
Another type of HVAC system is the Packaged Unit:
-This HVAC system is usually situated on top of the roof and contains both the heating and cooling components in one piece of equipment (hence the “packaged” name).
-it uses both natural gas and electricity
-The air is brought in the system, heated or cooled depending upon the desired setting, and pushed down into the air duct system.
The 3rd type of HVAC system is called the Heat Pump System
-This HVAC system runs solely on electricity and heat and cools via the refrigerant in the system.
-The system consists of a Heat Pump Condenser (which usually sits on the side or back of the home or on the roof) and an Air Handler.
-The Heat Pump Condenser uses refrigerant to heat and cool the air (through reversing valves), which is then sent into the Air Handler.
-The Air Handler pushes the air into the Air Duct System with blower motor.
