How To Save Light With Air Conditioning




In summer, the use of air conditioning can account for up to 70% of a home’s electricity consumption. So that your bill does not skyrocket.

Another summer is coming and, again, consumers are asking the same question: how can I save light with the air conditioning? After the changes in the new electricity rate, it is logical that more than half of Russellville households (which are those that have this appliance) are trembling at the thought of the bill that can reach them when the heat presses and have to get hold of this appliance. It should be remembered that, according to the IDAE (the Institute for Energy Diversification and Saving), the use of air conditioning can account for up to 70% of electricity consumption during the summer period.

How much electricity does the air conditioning cost?

Refrigeration appliances such as air conditioning can have an annual consumption of up to 170 kWh per home, which represents 2.3% of the total energy consumed in an average Russellville home, according to the IDAE.

However, it must be borne in mind that this consumption will not be the same during all months. Air conditioning is only usually used during the summer, a period in which that 170 kWh per year can triple. This means that, during those months, the consumption of the air conditioning can reach 70% of the electricity bill.

To calculate the amount of electricity used by the air conditioning, you must also bear in mind that this device is not working 24 hours a day. A person sleeps an average of eight hours a day, in addition to working another eight, plus another hour that they may have commuted to work. If the amount of time that person can be a way for leisure or errands is not counted, the total time that they would stay at home would be, at a minimum, about seven hours a day.

You should also consider the energy the air conditioner needs to operate. This energy is measured kW, although in the trade it is often referred to as a frigory: the power unit that measures the amount of energy the appliance needs to cool a room.

To find out how much energy the air conditioner consumes, we are going to use the following example: a user who uses an air conditioner for seven hours a day consumes about 2 kW per hour. According to this consumption pattern, the user would be using 14 kWh per day.

Tips to save with air conditioning

Only the use of the air conditioning can mean an expense of about 60 euros per month, so it is more than advisable to follow these tips on how to save energy with this device.

  •  Keep it at a temperature between 24 and 26 ºC: to save light with the air conditioning it is recommended to maintain a stable temperature of between 24 and 26 degrees, always without exceeding 12 degrees of difference from the outside. It should be noted that, with each degree that the temperature drops, the appliance will be consuming about an additional 8%.
  •  Do not neglect the maintenance of the appliance: dirty air filters force the unit to consume more energy to cool the house. It is convenient to keep the equipment in perfect condition so as not to increase its consumption.
  •  Turn it off before leaving: if we are going to leave the house, it is appropriate to turn off the air conditioning half an hour before, since the house will stay cool and unnecessary consumption will be avoided.
  •  Install it in the right area: it is preferable for the appliance to be installed in a shady area, not near other appliances that give off heat and have good air circulation.
  •  Ventilate the house in the cooler hours: the best trick to save with air conditioning is to make efficient use of it. Therefore, instead of turning it on first thing in the morning, take advantage of cool mornings (and nights) to open the windows and let the breeze in. Of course: when it starts to get hot, it is advisable to close the windows to keep the house cool for most of the time.

What is the most efficient air conditioner?

In addition to learning how to save light with air conditioning, before buying this type of appliance it is advisable to previously analyze the air conditioning needs of the home in order to choose the most suitable equipment.

There is a wide range of air conditioning devices on the market, but some of them, despite having similar features, can consume up to 60% more. Therefore, it is advisable to follow the following recommendations before choosing the equipment:

  •  Know the different models available: if the home does not have a centralized air conditioning system, which is the most efficient, you will have to choose between the two models available on the market. On the one hand, there are the compact ones, which are the ones that are usually attached to the windows and have the air condenser and evaporator in a single structure. On the other hand, in split models, the condenser occupies a unit that must be placed outside the house and connects with the evaporator, located inside. The latter requires more space but also ensures greater capacity. There are also small transportable models, but having smaller condensers and evaporators make them less efficient.
  •  Pay attention to power: the electrical power that the air conditioning equipment must have will depend on the size of the home or room to be cooled. For example, for an area of ​​between 35 and 40 m 2 a power of 3 kW is adequate.
  •  Bet on the inverter system: inverter air conditioners are those whose compressor (that is, the motor) does not turn off when the desired temperature is reached but adapts its speed at the moment. In this way, greater comfort at home is achieved, as well as better energy efficiency, since an inverter air conditioner can achieve an energy saving of 30%, according to the IDAE.
  •  Take into account the energy label: a device that has the highest classification in terms of energy efficiency (currently B, although in the old labelling system it corresponds to A +++) can save about 30 euros per year. However, these devices are also more expensive, so you should do numbers to see if the savings make up for the initial outlay you will make.

Do you spend more to turn off and on the air conditioning?

One of the most frequent doubts that consumers have when using their air conditioning is whether it is convenient to turn it on only occasionally or leave it on throughout the day. To clarify this doubt, it is necessary to use common sense: if you are going to leave the house or you are going to leave the room where the air is working, it is better to turn it off, especially if you plan to be away for a long time.

However, if what happens is that you have already reached the temperature you want, it is better to leave it on. Although you can find inverter air conditioners on the market, which have a more efficient motor, even older appliances have a thermostat that allows them to regulate the temperature of the room where they are. Therefore, if it reaches the temperature set by that thermostat, it will no longer consume so much energy, because it will stop cooling the room.

The moment it starts to get hotter than the temperature set by the air conditioner, it will consume more energy again.

Therefore, the best way to avoid turning the appliance on and off and thus saving light with the air conditioning, with the consequent extra expense that it may take to put the appliance back into operation, is to keep it at a comfortable temperature.

For example, if you have the air at 16 degrees, the room will cool down faster, but there will come a point where you start to feel cold. In addition, it will require many more frigories to cool the room, which causes a greater consumption and, therefore, a greater use of light.

On the contrary, if you keep it at 26 degrees, the room will take longer to cool down, but then it will stay cool for longer without having to turn it off and turn it on again in a few minutes.

Other tips to save light at home

In addition to the tricks on how to save electricity with air conditioning, there are other guidelines that you can follow to get the least amount of electricity spent and, thus, save on your electricity bill.

  •  Compare the different rates: One of the most essential tips to save light is to use an electricity comparator with which you will know what offers are currently available on the market. By using a comparator and choosing the cheapest rate for your profile, you can save more than 160 euros per year on your electricity bill.
  •  Install double-glazed or double-glazed windows: they prevent cold leaks in summer (and heat in winter).
  •  Install awnings and seal doors and windows: by having awnings or shading elements and sealing the windows with weather-stripping you can achieve savings of up to 60% in home energy consumption.
  •  Wear appropriate clothing: to avoid abusing the air conditioning, as far as possible, it is advisable to choose fresh fabrics or cotton garments.
  •  Eat properly: drinking plenty of water and eating refreshing meals during the summer is essential to avoid heatstroke and dehydration, especially in children and the elderly.
  •  Opt for a fawned air conditioning is not necessary. With this type of appliance, especially the ceiling ones that distribute the air better and that have a very low electricity consumption, you can get a sensation of a drop in temperature of between 3 and 5 ºC.
  •  Use light bulbs: the LED bulbs not only save you money by making more efficient use of energy but are also more environmentally friendly.

In the end you must have to concern with your heating and cooling expert in Russellville, AR for proper guidance.
