The Basics of HVAC Systems
HVAC stands for heating, ventilation and air conditioning. This system is designed for heating and cooling the interior of a building. HVAC components generate cycles of warm or cool air to keep building environments, healthy, comfortable, and clean. The basic component parts are designed for intake, exhaust, supply, and return. HVAC systems, depending on the type of environment they will be installed in, are available in varying sizes and complex mechanical designs. HVAC systems supply filtered air which has been conditioned to certain temperatures to supply heat or cool air to each room of the building and to keep it circulating. The heating and cooling systems are also designed to pull-in external air to keep the inside of a building circulating fresh air.
HVAC Components
The different components of an air conditioning system includes the heating and cooling systems, a fan, a filter, vents, and sealed duct work. The heater heats up the air which passes through the filter, then the fan forces the warmed air through the duct work and out through the vents. Cool air conditioning systems reduce the air temperature by utilizing a copper or aluminum tubing line carrying liquefied refrigerant from the condensing unit to the evaporator coil, and then recycles the vaporized refrigerant back again.
HVAC – Commercial vs. Residential
Is there any difference between the HVAC components used in commercial and residential systems? They both work in almost the same way to cool and heat any given space, but there are three main areas where these systems are different: size, zones, and the draining system.
• Size: Heating and cooling a large commercial building may require a more extensive system which will cover a larger environment.
• Temperature zones: Multiple thermostats to control different areas of a large building are needed. The varying temperature controlled areas are known as “zones.” Residential HVAC units are now being created with temperature control systems which can affect individual areas of a smaller space such as home.
• Draining system: Commercial businesses have a more complicated draining system than a simpler residential system. A home is designed with one drainage pipe to empty a drip pan, but a commercial HVAC components system is designed with multiple drainage pipes to make sure that the water does not overflow.
DDC System
Innovative HVAC technology has been introduced into this heating and cooling system. Direct Digital Control (DDC) is the use of computers and microprocessors in conjunction with sensors and actuators to provide a closed loop control. HVAC has evolved from pneumatic systems, to electronic systems, and now micro-processor controlled units, which has greatly improved performance and financial costs. A smaller home or commercial building might use a single computerized HVAC controller, while a larger building may require a complex system of controllers which are divided into sections called “tiers.”
