AC Service in Yuba City, Twin Cities & Maryville, CA, and Surrounding Areas

Are you seeking AC service in Yuba City, CA? Vardell’s is your answer! Air conditioners use refrigeration to chill indoor air, taking advantage of a remarkable physical law. When a liquid converts to a gas (in a process called phase conversion), it absorbs heat. Air conditioners exploit this feature of phase conversion by forcing unique chemical compounds to evaporate and condense repeatedly in a closed system of coils. The compounds involved are refrigerants that have properties enabling them to change at relatively low temperatures. Air conditioners also contain fans that move warm interior air over these cold, refrigerant-filled coils. Central air conditioners have a system of ducts designed to funnel air to and from these serpentine, air-chilling coils.

Cooling Down Your Air

When hot air flows over the cold, low-pressure evaporator coils, the refrigerant inside absorbs heat as it changes from a liquid to a gaseous state. To keep cooling efficiently, the air conditioner must convert the refrigerant gas back to a liquid. To do that, a compressor puts the gas under high pressure, a process that creates unwanted heat. All the extra heat created by compressing the gas is then evacuated to the outdoors with the help of a second set of coils called condenser coils and a second fan. As the gas cools, it changes to a liquid, and the process starts again. Think of it as an endless, elegant cycle: liquid refrigerant, phase conversion to a gas/ heat absorption, compression, and phase transition back to a liquid again.

Chilling Indoor Air

It’s easy to see that two distinct things are happening in an air conditioner. The refrigerant chills the indoor air, and the resulting gas is continually compressed and cooled for conversion back to a liquid again. Next, we’ll look at the different parts of an air conditioner and how AC Service in Yuba City, CA & Twin Cities works to make all that possible.

The Parts of an Air Conditioner

AC Service in Yuba City, CA & Twin Cities - Vardell's Air ConditioningLet’s get some housekeeping topics out of the way before tackling the unique components of a standard air conditioner. An air conditioner’s biggest job is to cool the indoor air. That’s not all it does, though. Air conditioners monitor and regulate the air temperature via a thermostat. They also have an onboard filter that removes airborne particulates from the circulating air. Air conditioners function as dehumidifiers. Because temperature is a critical component of relative humidity, reducing the temperature of a volume of humid air causes it to release a portion of its moisture. That’s why drains and moisture-collecting pans are near or attached to air conditioners and why air conditioners discharge water when they operate on humid days.

Still, the major parts of an air conditioner manage refrigerant and move                                                                                   air in two directions: indoors and outside:

Main Components of an Air Conditioner

The cold side of an air conditioner contains the evaporator and a fan that blows air over the chilled coils and into the room. The hot side contains the compressor, condenser, and another fan to vent hot air from the compressed refrigerant to the outdoors. In between the two sets of coils, there’s an expansion valve. It regulates the amount of compressed liquid refrigerant moving into the evaporator. Once in the evaporator, the refrigerant experiences a pressure drop expands, and changes back into a gas. The compressor is a large electric pump pressuring the refrigerant gas to turn it back into a liquid. There are some additional sensors, timers, and valves, but the evaporator, compressor, condenser, and expansion valve are the main components of an air conditioner.

Variations in Air Conditioners

Although this is a conventional setup for an air conditioner, there are a couple of variations you should know about. Window air conditioners have all these components mounted into a relatively small metal box that installs into a window opening. The hot air vents from the back of the unit, while the condenser coils and a fan cool and re-circulate indoor air. More oversized air conditioners work a little differently: Central air conditioners share a control thermostat with a home’s heating system, and the compressor and condenser, the hot side of the unit, aren’t even in the house. It’s in a separate all-weather housing outdoors. The exterior condensing unit is often mounted somewhere on the roof in very large buildings, like hotels and hospitals.
