How Much Electricity does Air Conditioning Use?


The humble air conditioner has come a long way since its first appearance on the market as a cooling device for buildings and homes. In the year 2000, air conditioners used from 30% to 50% less energy than those models that were manufactured back in the 1970s. With newer designs, makers have discovered ways to make them for better efficiency.

Before moving on to the amount of electricity used up by air conditioning, it is of importance to understand how they work. Basically, an air conditioner works in almost the same way as a refrigerator, in that a pump and a circuit of tubes produces the cooling system. Inside the device is coiled tubing, usually made from copper that winds into two kinds of coils, evaporator coils and condenser coils. The cold, indoor evaporator coil cools the room while the hot, outdoor coil releases the heat outside. The assembled heat that is expelled is a result of the energy running through the machine as it works and does its job.

A refrigerant has a busy job

One of the major parts of an air conditioner is a pump known as a compressor. This pump moves a heat transfer liquid, called refrigerant, between the condenser and the evaporator. Both types of coils are surrounded by aluminium fins, and the compressor pushes the heat transfer liquid through a series of tubing and fins. This liquid evaporates after hitting the evaporator, drawing heat out of the indoor air, which then results in the observable decrease in room temperature. The refrigerant is then pumped to the condenser, where it condenses into a liquid again, removing heat.

Most people who have a wall air conditioner in their home can easily cut down on energy expenditure by turning the system on only when there are people around at home. Surely that makes perfect sense, right?! A well looked after and maintained air conditioner will cool the air pretty quickly, so they really should only be turned on when it’s deemed necessary. It’s also a great idea for homeowners to keep drapes or blinds closed on any windows that face the sun, thus reducing the amount of solar heat entering your rooms.

Getting the right kind of air conditioning

It may also be in your best interests to install a programmable thermostat, so that the home is cooled on a routine basis, which saves the homeowner the trouble of having to manually turn it off and on every time they leave and come back home.
