Pop Quiz – How does your A/C Work?

What are air conditioners? 

Air conditioners are a central heating and cooling system that draws heat energy from the outside and send it to the inside. 

How does an AC work as a device?

After installation, an air conditioner functions as a central heating and cooling device that distributes the cold air through a sheet metal duct by drawing warm air inside, absorbing its heat, and replacing it with cooler air.

Describe what goes on inside an AC’s cooling system.

Chemicals in your air conditioner quickly transform from gas to liquid and back again. These chemicals move heat from your home’s interior to the outside air.   

What are the three critical elements in an AC?

The compressor, condenser, and evaporator are the three main components of your air conditioner. The compressor and condenser of your air conditioner are usually found on the exterior of the device. The evaporator is located within the residence.

What is the role of the cooling fluid? 

As low-pressure steam, the cooling fluid enters the compressor. The pump compresses the gas/fluid, and the ions in the liquid are packed together closely. As the temperature and energy rise higher, the compressor forces both the molecules together.

How does heat get dissipated in an AC?

As a high-pressure, hot gas, this operating fluid leaves the compressor and travels to the condenser. Some fins function similarly to a car’s radiator, allowing heat to be dissipated more rapidly. As a result, the fluid is much colder as it exits the condenser. 

When does the solvent evaporate into smoke?

When the liquid enters the evaporator through a small, narrow opening and hits the passage’s other side, the pressure drops. As a result, the solvent starts to evaporate and transform into smoke.

Describe the role of heat in an air conditioner.

Heat is absorbed from the ambient air. This heat is needed to convert the liquid molecules into gas molecules. The evaporator’s metal fins also aid in the diffusion of thermal energy with the surrounding air.

When does the refrigerant become a low-pressure, chilled gas?

The refrigerant is once again a low-pressure, chilled gas as it exits the evaporator.

Where does the process of cooling begin again?

When the gas returns to the compressor, the process begins all over again. If this process does not happen, it is best to get your AC repair in Lexington, KY.

Describe the journey of air from the evaporator to the ducts.

A fan is attached to the evaporator, and it circulates air across the property. Then, via a fan, the air conditioner draws air into the ducts. This air is used to cool gas in the evaporator, and it is cooled when the heat is separated from it. The air is then blown back into the house through ducts.

When does the air conditioner get turned off on its own?

The air conditioner is turned off when the thermostat detects that the indoor temperature has reached the target amount. When the room begins to heat up again, the thermostat reactivates the air conditioner before the desired ambient temperature is restored.
