While we all want to be kept cool in summer and warm in winter, energy costs are rising every year. Whether you are purchasing an air conditioner that’s portable, a window/wall unit, a split system, or even a ducted system, there are several ways you may use it more efficiently so your invoices are kept low and you are helping the environment too.
Choosing an air conditioner
- Check how much electricity it uses — Compare the cooling/heating Input and output power consumption of different versions, which is measured in kilowatts (kW). Also look at the size of your room, home, or building, and if there are some other internal heat sources.
- Choose an inverter model with a variable-speed drive (VSD) – An inverter air conditioner (e.g. split systems) has a VSD set up on the fan motor that automatically varies the compressor’s speed. Therefore it runs at full speed when you have to cool the place quickly and it runs at a slower speed when cooling isn’t urgent.
- Select the ideal size — If it is too big to your place, it’ll have short heating or cooling cycles where it will change off and on, and this uses up a great deal of energy. When it’s too small, it’ll need to work harder to cool down or warm up the location. Have an expert carry out complete heating and cooling load calculations in your house or business to determine whether the air conditioner is the right size before you buy it.
- Compare energy rating labels — All these labels have a celebrity rating, from 1-6 stars, for cooling and heating efficiency. The more stars that an air conditioner has, the more energy-efficient it is, and the more economical it’ll be to run too. Super-efficient air conditioners may have a rating of 7-10 stars.
Heating and cooling tips
- Close all doors and windows — This will stop a non-air conditioned atmosphere, whether hot or cold, from flowing to the room, as well as stop your air conditioner from running for longer.
- Keep the area you are cooling or heating to a minimum — You can do this by closing the doors of other rooms which don’t require heating or cooling. You may even be certain that vents and thermostats in fresh areas are sectioned off.
- Examine the gap between the indoor and outside temperatures — Whatever the temperature is outside, do not cool down the room’s temperature to less than 8°C below it. Also, the smaller the difference between the inside and outside temperatures, the lower your heating costs will be. Do that by setting your thermostat at a high, comfortable temperature in summer months and ensuring humidity management if needed.
- Adjust the temperature depending on the season — Set your thermostat between 24-26°C in the summertime and 18-20°C in winter. For rooms that are used infrequently (e.g. toilets and storerooms), the temperature should be 16°C in winter.
- Don’t set your thermostat at a colder temperature than normal — Your house will not cool down any faster and may lead to overcooling.
- Use the economy mode — This will decrease electricity use by keeping moderate temperatures in the ideal problems.
- If you have a central cooling system, then use the zoning choices — This will allow air to flow into just certain regions of the house.
- If you’ve got a central air system, then have the fan shut off together with the compressor — Place the ‘auto’ mode on the fan setting to do this and use fans in individual rooms instead.
- Use portable or ceiling fans — All these can be used together with your air conditioner to spread the atmosphere quicker and more efficiently across your property. You can also get portable air conditioning units for rent at the most affordable price to fast cooling in summer.
- Ventilate during the night or early in the morning — Close the windows during the day and open them at night or in the early morning to let in some fresh air.
- Turn it off when the temperature drops — You can then let the cool air inside by opening the doors and windows.
- Switch off other inner heat sources — These include lighting, computers, ovens, and printers. They can add to the heating load, so turn them off when not being used.
- Use energy-efficient lighting and office equipment — They will not emit as much heat as less-efficient products. For lighting, use compact fluorescent light bulbs.
- Only use it when needed — Your air conditioner should only run when you are using the room. For industrial buildings, it should be turned off at the end of the business day and on the weekends.
- Use timers — You can reduce the number of hours the air conditioning system operates due to using timers. The system will switch on when someone enters the room and switch off when they leave the room.
- Use a programmable thermostat — This is great for commercial buildings, as it will turn on the ac system 30 minutes until people arrive and turn off it 30 minutes before they leave at the close of the day.
- Ensure good air circulation around the inside and outside components — Remove curtains, furniture or plants which may be blocking the inside unit, and also clean the filter. For your outside unit, eliminate dust which might be obstructing the heat exchanger, as well as plants that are blocking the airflow.
- Cover the outside unit from the sun — Utilize an awning or a shade mesh to ensure the unit doesn’t overheat.
- Do not confuse the temperature sensors and thermostat — If there are additional heating sources near the air conditioner, like a lamp or TV, put them somewhere else in order not to influence the sensors on the unit or wall, as well as the thermostat.
- Don’t do things that will increase the room’s humidity — Don’t have a long hot shower, mop the floor or dry the clothes. Just do these things in the day when it’s cooler.
- Ensure ducting is free of air leaks — Cool air that Leaks will cool the interior of your roof in contrast to the interior of your home.
Long-term energy-saving tips
- Replace your old air conditioner with an energy-efficient one — Look for the ENERGY STAR label and compare Energy Guide labels. When compared to standard models, a room air conditioner with those labels is 10% more efficient, and also a central unit is 15% more efficient. In general, energy-efficient air conditioning systems use up to 40% less electricity than older models…
- Use a heating ventilation system —This may use waste energy from exhaust air to state incoming fresh air.
- Take advantage of waste heat —If your business utilizes heat-generating procedures like cooking or dispersed generation, use heat recovery to capture free waste heating.
- Insulate the home or building —Insulate roof spaces, walls, and pipes to reduce heat loss in winter and heat gain in summer. Cold and hot air ducts must also be insulated.
- Install double-glazing windows —They can also significantly reduce the amount of heat lost during winter and the quantity of heat that enters during summertime.
- Color the window from outside —Utilize an awning, shutters, blinds, curtains, or tinting to reduce the amount of sunlight entering the room in summer, which can decrease the room’s temperature by a few degrees. In the winter, keep them open throughout the daytime and closed at night.
- Use skylights —They allow natural light to go inside, which is excellent during winter months. In summer, however, consider covering them up.
- Use a dehumidification system —If you live in a humid climate, this can raise your comfort when it’s very hot, which means that you may just use a small air conditioning system.
- Consider installing economizers —They are great for when the temperature outdoors is lower than the temperature indoors. They will take fresh outdoor air to cool the inside, so you won’t have to use the indoor portable air conditioning units to cool the inside with recirculated air.
- Utilize an energy management system —It’s ideal to use this if your air conditioning system can’t be controlled with timers or thermostats. You can use different cooling and heating temperatures for various zones, stop times, optimum gear start, and more.
- Maintain it regularly —Follow the manufacturer’s maintenance instructions to make sure that your air conditioner is functioning as it needs to be. Including keeping the system, in addition to replacing and cleaning the filters regularly.
- Get it checked by a specialist at least once a year —A specialist can confirm whether the air conditioner is at tiptop shape by checking that all the functions are working correctly.
When used properly, air conditioners can create an environment that feels agreeable and comfy. And together with these energy-saving tips, you can decrease your energy bills and be more eco-friendly at precisely the same time.
