Why does inverter Air Conditioning save more on Electricity consumption?
Well, the main reason is in the component that consumes the most electricity from all the equipment, and this is the engine or compressor.
In a conventional air conditioning machine the compressor is always operating at 100% capacity, i.e.:
Let’s imagine that we get home and it’s awfully hot, for example, 30oC, and we put our air conditioner at 25oC because until the temperature drops to 25o the compressor will be running at maximum performance, that is, at 100% of its capacity. Once the appliance has managed to lower the temperature to 25o what happens is that the compressor is s stop, and the moment the temperature rises again it will start walking again.
Why does it save more inverter equipment than conventional ones?
Well, the main reason is that it is able to control, through an electronic plate, the frequency of the electric current, which normally reaches our homes between 50 and 60 hz, and that it is able to control from 5 hz to 120 hz (reaching to increase the capacity of the compressor up to 30% more) And what does this mean? Since varying the frequency varies the turning speed of the compressor, being able to operate from 10% to 100% of its capacity.
In this way the compressor saves on a day of operation many starts and stops, saving in a year between 30 and 60% in electrical energy.
Putting the same example above, if we get home and have a temperature of 30o C and put our system at 25o C, the compressor as it approaches 25o will slow down, reducing its performance to 10% of its capacity, thus achieving great energy savings in addition to saving us the multiple starts and stops of the compressor.
The inverter compressor reaches fewer decibels than that of a conventional machine, especially when the compressor starts to lower its performance. In this way, it is less likely that over time they will start to look like sheet metal noises because of the dilations of the materials since the compressor is quieter and causes fewer vibrations.
Another advantage is that by lowering its performance as it reaches the temperature we ask the compressor reaches fewer revolutions so that the compressor is 100% sure that it will last longer than a normal compressor.
As you may have seen, this system is always more cost-effective than conventional equipment, mainly because of energy savings. So if you’re planning on buying an air conditioner, I hope you know what kind to buy it from.
One of the drawbacks is that they are more expensive than conventional ones, but everything you’re overspending now will make a big recovery on your electric bill.
These units achieve greater stability of the setpoint temperature. This means that if we select a temperature of 22 oC, for example, the equipment will keep the ambient temperature much better, this is because the compressor suffers fewer stops and starts, regulating its speed and making the temperature more stable.
In the following image, you can see perfectly what we are explaining.
As you can see an all-or-nothing (conventional) air conditioner suffers more stops and starts, which is equivalent to the selected temperature having more variations, however an inverter system by regulating its operating speed achieves a more stable temperature.
This is the largest workhorse of inverter units, consumption, performance.
It is clear that among the improvements with respect to fixed speed units this is the most essential, thanks to electronics and obviously the rest of the advances in these years, a current inverter unit is able to achieve an energy factor of five commas fifteen that is equated with a two with seventy-six of the same non-inverter model is something to consider.
It is practical twice the performance and therefore this means half the consumption to do exactly the same work and air conditioning exactly the same room, only for this reason choosing between an inverter unit and one that is not should be a simple choice for anyone.
Higher operating range
Another peculiarity where this system far exceeds a conventional unit is in the operating range, especially in the heat pump.
An all-or-nothing unit when the outside temperature reaches between five and zero degrees begins to lower performance in a very abrupt way, becomes even ineffective and also useless for it to continue marching if it lowers, even more, the outside temperature.
This is because when you go in heat pump the outdoor unit will be cooling and there comes a point where it starts to generate frost and ends up freezing making it impossible to exchange heat or cold outside, this is solved with the so-called “defrost” or defrost that almost all units of this class have.
With this defrost what the air conditioning unit does is send over a few minutes the heat that should go face the indoor unit to heat our house faces the outdoor unit to make a “thawing” of this, losing in the process that heat that would be driving in the indoor unit.
After this, the unit will start again normally until the next de-scratch that will be but frequent and shortened in time against colder and more moisture done on the outside.
The inverter units do not have this inconvenience or if they always have it and at all times it is much less pronounced while the electronics the process itself regulates the flow of the gas so that this does not happen according to the measurements made by the temperature probes going up to -fifteen degrees of outside temperature and losing much less performance than the all-or-nothing air conditioning units.
In addition to this, unique units for operation up to less than twenty-five degrees of outdoor temperature, giving a performance of one hundred per cent up to at least fifteen degrees like Mitsubishi Electric units.
What is the inverter system?
When buying air conditioning equipment one of the most important points where we have to look is in the electricity consumption, and the best thing for these cases is the inverter system.
It must also be said that to save on electricity consumption the ideal is to install an air conditioning equipment with the cooling power necessary to meet the needs of our premises, I say this because there are many people who by saving a few euros buy a lower power machine, and this, in the long run, comes out more expensive. So first of all, it’s best to make sure the power we need and then find the equipment that suits us best.
An air conditioner with inverter system has several advantages that conventional equipment does not have. Less outdoor unit noise, higher compressor performance and, of course, lower power consumption.
What is an A/A inverter?
It consists of an electronic control system that is used to control the rotation speed of the compressor and with it the amount of gas that is able to displace, (the more speed more gas moves through the refrigeration circuit and at a lower speed less amount of gas in motion), in this way, the compressor adapts its power to the refrigeration needs of the premises or premises with the consequent saving of energy and mechanical effort, since it does not have as many starts and stops.
To control the speed of the compressor drag motor, the electronic board varies the frequency of the power supply (50 Hz) by operating the motor from approximately 5 Hz to 50 Hz. Therefore, the power of the outdoor unit can be biased from 10% to 100% depending on what the indoor units demand. It is known as the first generation of the inverter.
The second-generation inverter system also works by raising the frequency to 120 Hz, increasing the compressor power by 30%. This property is used to get the setpoint temperature in the shortest possible time and then acts as a first-generation.
Finally, I will tell you that it is always more efficient than an all-or-nothing system, so if you are thinking of buying an air conditioner and your pocket allows you, I recommend that you opt for the inverter system, it is always something more expensive but in the long run, you can get some good savings on the electricity bill.
Tips for increasing efficiency and reducing consumption
The electricity consumption of our homes is today one of the most important points of our day today. As much as the electrical appliances we have at home consume less and less the price of electricity does not stop going up.
There are a lot of people who think that for our air conditioner to cool down faster and get colder, we have to put it to a minimum of temperature, but that’s a profound mistake!!
The air conditioning always has the same temperature, no matter if you put it at 16o or 30o, what happens is that when the room reaches the temperature we are asking, the machine stops and stops cold. So don’t put your device in full milk because all you’re going to get is to spend more electricity.
That said we’re going to see some points that make saving electricity on our electricity bill possible.
Tricks to Save Electricity
1. Install a machine with enough power to meet the needs of our room or room. And I say this because many people, by saving a few euros, install a lower power air conditioner and then that has a direct impact on the electricity consumption, so if you haven’t installed it yet I recommend you do the corresponding calculation of refrigerators and buy one with enough cold power.
And why do you consume more? because an air conditioner when it reaches the temperature that we are asking, for example, 25o, the compressor will stop, and when the temperature rises again it starts to work again. If you have a smaller machine it is safest that it never stops or that it takes much longer to do so, consuming much more energy.
2. Clean filters regularly and exchangers, as well as perform good maintenance to your A/A team.
3. Set the temperature to 25o. Although this also depends on each person, I say this because you at 25o may be comfortable but nevertheless I can be roasted for heat. This temperature thing is very relative, although it is true that depending on how we use it the savings will be greater or lower. But come on, you’re already on, instead of putting an air conditioner on it, think about it better and if that can put a fan better on the ceiling and that’s it.
4. Keep whenever we have the appliance on all doors and windows tightly closed, otherwise hot air will enter the room and the machine will not stop walking, consuming more energy.
5. Take advantage of the first hours of the day to ventilate the house and thus cool off, after this close everything. It may seem silly, but that’s how we’ll be able to lower the temperature of the structure by several degrees.
Myths and truths about equipment consumption
Do you think air conditioning is the biggest villain on his electricity bill? Do you know that a device well installed and sized correctly consumes less energy than your daily shower? for example.
There are many consumer questions about air conditioning energy consumption, and that’s why we’ve decided to uncover the main myths and truths about this.
- Installation does not interfere with power consumption: If the installation is performed correctly indicated by the manufacturer favours the appliance. An installation performed differently than that recommended by the manufacturer interferes with the operation of the installation by consuming more energy. (Myth)
- There is a suitable type of equipment for each environment: There are devices suitable for every environment size, intensity, and flow of people. (Truth)
- Temperature does not interfere with energy consumption: Keeping air conditioning at minimum temperature (cooling) and maximum (heating) consumes more energy. Keeping the room at a temperature between 22oC and 24oC avoids unnecessary energy costs and is more suitable for the human body (Myth).
- The condenser can be in a closed area and does not influence consumption: The outdoor unit has to be in a place where there is no air circulation to prevent the return of the supply air (Myth).
- The most economical inverter systems: The inversion apparatus of the function as a frequency converter, to control the speed of compression equipment. The compressor does not turn off, avoiding voltage overloads and temperature fluctuations (Truth).
- More power-consuming equipment: A device with 18000 refrigerators consumes more power than a 12,000-minute unit, for example. But be careful as using a device with less power than indicated greatly increases your power consumption. So the right size is very important (Truth).
- To reduce power consumption it is ideal to turn off the equipment when leaving the room: Turning the equipment off and on too often leads to higher power consumption. If when leaving the room for a short space of time we turn off the air conditioning we will be causing consumption spikes at each new start (Myth).
- Leaving the window open with the air conditioner connected increases power consumption: In addition to consuming more energy, this omission may endanger the appliance. Ideally, leave all doors and windows tightly closed (Truth).
- Keeping filters clean avoids unnecessary energy costs: Dirty filters prevent free air circulation, forcing the unit to work harder and therefore consume more energy (Truth).
- Procel-sealed devices are cheaper and healthier: The Procel Seal identifies the most economical equipment, according to the energy efficiency measured by the EEC (Energy Efficiency Index) and the higher the EEC, the more efficient and economical the device will be. The classification is divided into A, B, C, D and E (Truth).
Air conditioning doesn’t really have to be the worst villain of beads, just use it properly, keep filters clean and perform preventive maintenance.
