A modern marvel
Cooling you off in summer’s most unforgiving temperatures, 80% of home owners now rely on air conditioning – mostly central. This feat of engineering offers comfort essential to quality of life. But not many understand its function.
The “split” system
Split systems, the most commonly used central heating and cooling units such as systems by Bryant air conditioning and heating, operate much like your refrigerator. Rather than an insulated icebox, however, your home’s walls contain cooled air. How is this air cooled? Science and mechanics.
The cooling concept
Utilizing principles of physics, air conditioners take advantage of a process called “phase conversion,” in which when liquids are converted to gas, they absorb heat. Using special chemical compounds – refrigerants capable of changing at relatively low temperatures - central air conditioners complete the conversion process over and over in a closed system – your A/C’s serpentine coils – funneling warm interior air over them to condition it to a cooler temperature, then distributing it via ductwork.
Phase conversion in action
To complete phase conversion – and deliver cool, conditioned air through your home, the cooperative effort of a gaggle of components is necessary.
- The indoor cabinet
Fans blow air across your indoor unit’s evaporator coil, transferring heat to the outside air by carrying it to the outside cabinet via refrigerant in the coils. - The outdoor cabinet
Once heat energy is carried to the outside unit’s condenser coil by the refrigerant, the refrigerant is pumped back into the compressor, thus beginning the cycle again. What happened to the heat? It was moved outside when the cooled air was blown in, as was any moisture via condensation (hence the name “condenser” coils). - Other major components your central air conditioning system relies on include…
- The blower (fans)
Which distribute air over the coils to improve heat dissipation and distribute them to the rooms being cooled. - The expansion valve
For controlling refrigerant flow. - The thermostat
Which regulates operation by monitoring air temperature. - The filter
To removes airborne particles that can reduce air movement and clog system components. - Drains and moisture collection pans
For reducing humidity in indoor air and the moisture that is a natural by-product of temperature reduction.
