How Your Air Conditioner Cools Your Home
An air conditioner cools your home by removing heat and moving it outdoors. This works by using chemicals that change from gas to liquid and back again quickly.
This LG model offers a variety of convenient features, including a remote control and programmable 24-hour timer. It also provides auto, dry, and eco settings to help achieve the ideal temperature.
Evaporator Coil
The evaporator coil inside your air conditioner (and heat pump, if you have one) is responsible for blowing cool air into your home. It’s made of copper tubes that can efficiently conduct heat, and it works side by side with the condenser coil to absorb and release heat.
In other words, without the evaporator coil, your AC won’t produce cold air at all. It’s located in the indoor part of your AC unit, or air handler, and it is inside the blower compartment along with the furnace.
When warm indoor air blows over the coil, it’s absorbed by the refrigerant that’s running through the copper tubing connecting your indoor and outdoor units. As it absorbs heat, the moisture in the air turns into water vapor, which is then dispersed throughout your home to lower the temperature of the air.
The evaporator coil should be cleaned on a regular basis to keep it working properly. If it becomes clogged with dirt and Air conditioner debris, the air conditioner’s fans will have to work harder to create the desired cooling effect in your home, which can expedite wear and tear on other AC components. To clean the coils, you can use a brush or spray cleaner (follow the instructions on the label) to remove any dirt buildup. If you use a cleaning solution, it is recommended to wear eye protection and gloves to prevent chemical exposure.
Compressor
The compressor is one of the most important parts of your air conditioner because it circulates refrigerant throughout the system. It is responsible for changing the refrigerant from a liquid to a gas, and back again. This change in temperature is what helps make your home cool and comfortable.
The air conditioner compressor is a machine that decreases the volume of a refrigerant by forcing it between two metal surfaces. These metal surfaces are usually hermetically sealed so that no leaks can occur. There are many different types of compressors, but the most common is the screw compressor. This type is reliable and efficient, and it can be used for large industrial cooling systems.
This type of compressor compresses the refrigerant by reducing its volume through the use of a rotating impeller. Its design increases its power and efficiency. It is also more quiet than other types of compressors.
The compressor can be compared to the heart of an air conditioning system. It pumps the refrigerant around the system to ensure it works properly. If the compressor is not functioning properly, it can cause your air conditioner to malfunction and stop working. You should call Snell if you notice any signs that the compressor is not working correctly. We will send one of our technicians to repair or replace the compressor as quickly as possible.
Condenser Coil
The condenser coil, also called the outdoor coil, is in your air conditioner’s outdoor unit. The function of this coil is to reject the heat absorbed by the evaporator coil from your home’s indoor air. The refrigerant then transfers this rejected heat to the outside environment.
To do so, the coil needs a certain amount of pressurized coolant. If this coolant level becomes too low, your system might fail to transfer enough heat, or even shut down completely. Call an AC service specialist to check your refrigerant levels.
As mentioned, your evaporator and condenser coils need regular maintenance to work correctly. The most common problem with these coils is a build-up of dirt on the outdoor coils. If the coils are covered with dirt, they cannot reject heat effectively and your air conditioner will require more energy to run.
You can clean the evaporator coils using a coil cleaner, which you can find in most big box hardware stores. However, it is important to keep in mind that your air conditioner is a highly charged 240V system, so you should disable its electricity before working on it. Then, you should take the proper safety precautions – you will need safety glasses, a face mask and chemical-resistant gloves. Make sure you have sufficient ventilation too, since the chemicals in a coil cleaner are hazardous.
Thermostat
Often the most overlooked component of your air conditioner, the thermostat is responsible for turning your air conditioning system on and off according to your temperature settings. The thermostat reads the ambient room temperature and uses this information to determine when it’s necessary for the rest of the AC system to turn on.
This is a fairly simple Air conditioner little device, in its most basic form it is nothing more than a switch connected to a temperature sensor. Older systems use capillary tubes filled with alcohol, but most modern thermostats are digital and rely on solid state devices such as thermistors or thermopile powered “millivolt” circuits.
A bimetallic strip is wound into a coil with one end attached to a moving contact (usually a mercury switch). As the coil gets warmer the bimetallic strips expand and tips the switch to the left, this in turn allows current to flow through the mercury which then energizes a relay that turns on the heating system.
The thermostat also has a display that shows the current temperature and your setting. Some models have a set of up and down arrows that allow you to adjust the desired temperature. Most of today’s thermostats can be programmed to turn the HVAC system ON and OFF at specific times of the day based on your schedule.
