You have heard the low humming sound it makes when it turns on, but you have likely never peered in to see exactly what is going on inside your air conditioner. Understanding how your unit works can help you provide the proper air conditioning maintenance and perform adequate HVAC repair in Tampa. These factors will allow you to enjoy your air conditioner’s long and efficient working life. Keep reading if you are interested in learning a little bit about the science behind air conditioning.
What Happens Behind the Scenes
People know air conditioners as the boxes in their yards and windows that keep their homes comfortable throughout the summer. However, not many people recognize the processes of evaporation and condensation that go on inside these boxes, and thus are relatively clueless when it comes to air conditioner repair. Your air conditioner creates cool air using a substance called a refrigerant. This refrigerant evaporates at a low temperature inside metal coils; once the refrigerant evaporates, the coils cool. A fan blows air over these cool coils, and this newly cooled air circulates through your ductwork and into the various rooms of your home. Your unit’s compressor then causes the refrigerant to condensate and turn back into a liquid, which creates heat. Another fan expels this heat to the outside of the unit, and the refrigerant continues the cycle by evaporating again.
Two important acronyms that describe different aspects of air conditioners are Btu and EER. Btu stands for British thermal units and tells you how much heat is required to heat one pound of water by one degree Fahrenheit. Btu is important when it comes to choosing the right size unit for your home. EER stands for Energy Efficiency Rating and compares a unit’s Btu with its wattage. Higher EER ratings mean more savings.
The Energy Efficiency Difference
An energy efficient air conditioner makes the most of the power that it is given. This means that you will save money on your energy bills and reduce your home’s carbon footprint at the same time. These units also tend to last longer.
