Every year, though we all want to be kept cold in summer and hot in winter, energy prices are rising. There are several ways that you can do it more easily, whether you have or are buying a portable air conditioner, a window/wall machine, a split system or a ducted system, so that your costs are kept down and you are still benefiting the climate.
Choosing a conditioner for air
Compare the cooling/heating input and exhaust power consumption of various models, which is calculated in kilowatts, to see how much energy it uses (kW). Consider the size of your bed, house or home, too, and whether there are any other sources of internal heat.
An inverter air conditioner (e.g. split systems) has a VSD mounted on the fan motor that dynamically adjusts the compressor’s rpm. Select an inverter model with a variable-speed drive (VSD). So, when you need to cool the area quickly, it runs at maximum speed and when cooling is not urgent, it runs at a slower speed.
If it is too heavy for your venue, it will have quick cooling or heating periods where it will turn on and off, which takes a lot of electricity. Shutterstock 124533580 Pick the correct model. It will have to work harder to cool down or warm up the place if it’s too small. Get a technician in your home or organization run complete heating and cooling load calculations to decide whether or not the air conditioner is the correct size before you purchase it.
Compare energy rating labels: These labels have a star rating for cooling and heating efficiency, from 1-6 stars. The further stars an air conditioner has, the more energy-efficient it is, and the less costly it would still be to operate. Air conditioners that are super-efficient will get a rating of 7-10 stars.
Tips for Heating and Cooling
This would stop non-air conditioned air, whether hot or cold, from streaming into the room, as well as stop the air conditioner from working any longer. Close all doors and windows.
You can achieve this by shutting the doors of other rooms that do not need cooling or heating. Keep the space you’re cooling or heating to a minimum. You should also make sure the vents and thermostats are sectioned off in unused areas.
Test the disparity between indoor and outside temperatures; do not cool down the room temperature to less than 8 ° C below it, regardless of the temperature outside. Often, the greater the difference between the temperatures inside and outside, the lower your cooling costs would be. Do this by setting your thermostat in summer at a high, comfortable temperature and maintaining, if necessary, humidity control.
Set your thermostat between 24-26 ° C in summer and 18-20 ° C in winter, changing the temperature depending on the season. The temperature should be 16 °C in winter for rooms that are used infrequently (e.g. toilets and storerooms).
Do not set the thermostat at a cooler than normal temperature. Your house may not cool off quicker and can overcool.
Using the economy mode by keeping mild temperatures in the right conditions, which would decrease energy use.
Use the zoning choices if you have a central cooling system. This would allow air to circulate only to some parts of the building.
Have the fan turned off along with the compressor if you have a central air system. Set the ‘auto’ mode on the fan setting to do this and use fans only in individual spaces.
These can be used along with your air conditioner to disperse the air quicker and more effectively in your home, using handheld or ceiling fans.
Shut the windows during the day and open them at night or in the early morning to let some fresh air in. Ventilate at night or early in the morning.
Switch it off as the outside temperature decreases. By opening the doors and windows, you will then let the cold air inside.
Switch off all sources of internal heat, including lights, monitors, printers and ovens. They will contribute to the heating load, so when not in operation, turn them off.
111 They would not emit as much heat as less-efficient goods, using energy-efficient lamps and office appliances. Using compact fluorescent light bulbs for illumination.
Use it only when appropriate. Only when you use the space does your air conditioner operate. It can be turned off at the end of the workday and on the weekends for industrial buildings.
Using timers- By using timers, you can decrease the amount of hours that the air conditioning system operates for. When anyone enters the room, the machine will turn on and switch off when they leave the room.
Using a programmable thermostat- This is perfect for industrial buildings, since 30 minutes before customers enter, it will turn on the air conditioning system and turn it off 30 minutes before they depart at the end of the day.
Remove curtains, furniture or plants that can obstruct the inner unit, and also clean the filter, to ensure proper air ventilation across the inside and outside units. Remove dust that could be blocking the heat exchanger, as well as plants that obstruct the ventilation, for the outside device.
Using an awning or a shade mesh to ensure that the unit does not overheat, or protect the outside unit from the light.
If there are other heat sources near the air conditioner, such as a lamp or TV, position them somewhere else so as not to disturb the sensors on the wall or unit, as well as the thermostat. Don’t confuse the temperature sensors and thermostat.
Don’t do things that raise the temperature in the place. Don’t have a long hot shower, mop the floor or dry the clothing. Just do those things when it’s hotter in the evening.
Make sure that the ducting is free of air leakage. The interior of your roof will cold the cool air that escapes rather than the inside of your house.
Energy-saving long term tips
Check for the ENERGYSTAR logo and compare the EnergyGuide labels to swap your old air conditioner with an energy-efficient one. A room air conditioner with these marks is 10 percent more effective as compared to regular ones and a central unit is 15 percent more efficient. Overall, air conditioning units that are energy efficient consume up to 40 percent less energy than older ones..
Using a ventilation system for heat recovery. It would use excess energy from exhaust air to condition new incoming air.
If the company uses heat-generating processes such as cooking or distributed generation, use heat recovery to collect free excess heat. Shutterstock 107258300 Make use of waste heat.
Insulate the house or building to minimize heat loss in winter and heat gain in summer by insulating roof spaces, floors, walls and drains. There can also be sealed hot and cold air ducts.
Install double-glazing windows-the amount of heat losing during the winter and the amount of heat arriving during the summer will both be greatly decreased.
Using an awning, shutters, blinds, drapes or tinting to minimize the amount of sunshine entering the room in summer, which will reduce the temperature of the room by a few degrees. Shade the window from outside. Hold them open during the day in winter and locked at night.
They encourage natural light to reach the interior, which is perfect during winter, using skylights. However, in summer, consider covering them up.
Using a dehumidification system. If you live in a tropical environment, when it’s very hot, this will improve the convenience, meaning you can only use a small air conditioning system.
Try building economisers. They are perfect for when the outside temperature is colder than the indoor temperature. To cool the inside, they will take fresh outside air, so you will not need to use the indoor air conditioner to cool the inside with recirculated air.
If the air conditioning system can not be operated by timers or thermostats, it is safer to use an energy conservation system. For different areas, stop hours, optimal equipment start, and more, you should use different cooling and heating temperatures. shutterstock 159415724 Keep it constantly Follow the servicing directions of the manufacturer to ensure that the air conditioner is working as it should be. This means repairing the scheme, as well as constantly washing and changing the filters.
At least once a year, have it tested by an expert. A specialist will ensure that the air conditioner is in tip-top condition by ensuring that all the functions are functioning correctly.
Air conditioners can make any area feel friendly and relaxed when used properly. And you can reduce your energy costs and be more eco-friendly at the same time with these energy-saving tips.
How much power is being consumed by your air conditioner? Plus, how much would your air conditioner actually cost to run? Spoiler: It is less than you would have thought.
A new Canstar Blue study showed that to save money on their energy costs, many Australian households have cut back on using their air conditioning. Our findings found that nearly two in five survey respondents (38 percent) suspect that air conditioning is the largest contributor to electricity bills, so it’s no wonder that a comparable number of individuals (33 percent) said that when considering an air conditioner, energy efficiency was their number one determining factor.
On the Government of South Australia website, you can look up the wattage of an air conditioner and measure the average operating costs of equipment, but in the meantime, here’s our rundown of the energy cost figures, whether you’re using your aircon for heating or cooling. For these measurements, we have assumed an energy consumption fee of 35c/kWh.
How much does it cost to operate a refrigerated air conditioner?
The typical reverse cycle air conditioner costs about $0.25-$0.35 per hour to operate for cooling purposes, based on the size of the room. Air Conditioners Energy Costs Infographic It will cost $0.36-$0.70 per hour for a medium-sized space of 36sqm to work. It would cost between $0.70 and $0.95 per hour in wide areas (50sqm).
Around $0.45-$0.55 per hour, a portable refrigeration unit costs almost the same.
The real cost champions, but maybe not cooling power, are ceiling fans and compact fans, based on fan speed, at only $0.02-$0.05 per hour. In a near second, compact evaporative systems come in, charging about $0.06-$0.07 for power per hour, plus less than $0.02 per hour for the water needed to cool the air by the unit.
The main money pit, at $2.45-$3.45 per hour to work, is once again a ducted whole-house reverse cycle air conditioning system. That’s a lot more costly than using the heating machine, but if you want every inch of your house or office to be freezing cold, well…
How much does it cost to operate a heated air conditioner?
Using a reverse cycle air conditioner to steam a room normally costs $0.13 – $0.36 per hour.
At around $0.36 per hour, an electric radiant heater costs about the same as an electric panel heater at $0.43, but none of these would heat an area as large. At $0.43-$0.51 per hour, a gas heater costs higher.
At $1.45-$2.12 per hour, a ducted whole-house reverse cycle air conditioning system costs the most, just make sure that you truly need it before clicking the bell!
Adding up the prices
While the above-mentioned basic hourly operating costs don’t sound that alarming, bear in mind that these costs will add up easily over time. For starters, it’s likely to add an additional $200 to your next power bill to operate your split device air conditioner for cooling four hours a day in the summer months. You should plan to spend about $1,000 for the comfort during summer if you have ducted air conditioning. Before, you’ve used the word’ bill shock,’ right? It helps, of course, if you get a nice deal on energy.
