Some Sacramento homeowners may think that their AC works by removing hot air from the home and replacing that hot air with cool air. However, this is far from the truth. Read on and learn how experts from Fox Family Heating & Air, a Sacramento heating and air conditioning company, explain how your air conditioner works in order to cool your home during the hot months of the year.
Two Synchronized Movements
Two kinds of movement work together to deliver comfort to you in your home. The first movement involves the sucking of warm air into the vents in your home. Remember, warm air rises, so the warmest air in your home is the one that gets sucked into the vents for circulation through the AC system. This same air returns through the return air registers when it has cooled down. How it cools down is connected to the second kind of movement in the AC system.
The second movement has to do with the refrigerant in the AC. This refrigerant is cold before it gains heat from the air moving around it. The refrigerant then heats up and goes through a system that cools it before returning it to absorb more heat. The same refrigerant keeps undergoing these transformations without needing to be recharged. You should, therefore, contact air conditioning repair experts in Sacramento in case you see any signs of a refrigerant leak. The process of heating then cooling the refrigerant will become clearer once you understand the workings of the two key parts of the air conditioning system as discussed below.
The Indoor Unit
The indoor unit of an air conditioner is normally installed in the basement or the attic in most homes. The main component of this indoor unit is the evaporator. The evaporator has coils within which a refrigerant circulates. The refrigerant is initially cold.
The hot air which has been sucked by the vents in the different rooms of your home passes over these coils containing the cold refrigerant. The refrigerant absorbs the heat from this warm air and that heat causes the refrigerant to turn into a gas (that is why the unit is called the evaporator). The air is now cool and is returned to the different rooms in order to make you feel more comfortable.
Meanwhile, the heated refrigerant (which is now a gas) travels towards the outdoor unit in order to be cooled so that it can absorb more heat from the next batch of heated air coming from the rooms in your home.
The Outdoor Unit
The main components of the outdoor unit of your air conditioner are the compressor and the condenser. The heated air from the indoor unit travels out and finds the compressor. This compressor pressurizes the heated air and pushes it towards the condenser.
The condenser has fins similar to those in the radiator of your vehicle. These fins provide a large area into which the compressed refrigerant is released. The large surface area allows the pressurized gas to spread out.
Meanwhile, fans blow air across the surface of the fins into which heated air has been released. That ambient air absorbs the heat from the refrigerant and the refrigerant cools. The refrigerant converts into a liquid as it loses heat to the air around the condenser fins. That is why this section of the outdoor unit is called the condenser (it facilitates the condensation of the hot refrigerant gas into a cold liquid). This cold liquid flows towards the indoor unit where it will absorb heat from the warm air coming from the vents in your home. You may need to consider air conditioner replacement (Sacramento) in case a major component, such as the compressor, fails and the outdoor unit can no longer do its work.
The process described above is repeated until the thermostat detects that the temperature inside the home has dropped to the desired level. A signal is then sent to the control unit of the AC to shut off the system. Another signal will be sent later to restart the system once the thermostat detects that the temperature has risen beyond the set level. Your AC keeps cycling on and off throughout the day in order to keep the home at the desired temperature.
The discussion above only covers the basics of how your air conditioner works. Other activities, such as the removal of contaminants (by the filter) and the removal of excess humidity (by the dehumidifier) take place while the heated air is moving from the rooms to be cooled and then returned once more.
Any defect at any point of this well-coordinated process will affect the degree of comfort that you experience in your home. That is why it is important to call AC maintenance and repair and repair professionals from trusted companies, such as Fox Family Heating and Air so that an inspection can be conducted to locate and fix the defect.
