Air conditioners increase energy bills, which can be an issue for many people, but the big impact can be cut down significantly by selecting an ideal technology, accurate installation, proper maintenance, and right room insulation.
Speaking about technology, since BEE got active in rating air conditioners people got some good 5-star units. Today, inverter technology is latest and efficient in terms of energy saving in comparison to regular air conditioners. Visit Amazon and check on the inverter technology details and specs.
Use of the latest Inverter technology in air conditioners has made buying them more economical. Let’s get familiar with the latest inverter technology and its operating concept of air conditioner equipped with the new technology.
What is the Latest Inverter Technology?
Inverter technology or DC inverter is the latest evolution related to compressors electro motors. Air conditioners equipped with DC inverters have constant control over the thermal transfer rate through modification of compressors speed, according to cooling demand. This concept can be compared to technology applied in vehicles, where you press the accelerator more for increasing speed.
What DC Inverters do?
In a standard AC, the compressor operates at a fixed speed [100% capacity], when started. On the other hand, an inverter unit will start at low level and slowly increase its capacity on basis of temperature needed to cool the room. Fixed speed compressors turn on and off, automatically to sustain desired temperature, but inverter unit control the compressor capacity.
How DC Inverters Work?
Variable frequency drive is used to regulate motor speed thus controlling compressor speed. Variable frequency drive incorporates a rectifier, which converts AC to DC. PWM {Pulse Width Modulation] from the DC inverter is utilized to generate AC [alternating current] of desired frequency. The AC drives an induction or brushless motor.
The induction motor speed and frequency of A are directly proportionate to one another compressors of Voltas AC unit equipped with inverter can operate at different speeds. Micro-controller is used to measure current air temperature and then the speed of compressor gets adjusted, accordingly.
Benefits of Investing in Air Conditioner with DC Inverter
- The on/off cycle get eliminated and efficiency of rapid cooling and heating gets improved.
- Component lifespan also gets extended due to elimination of start/stop cycle.
- Power supply fluctuations strains the unit, which gets removed.
- Outdoor unit operates quieter than conventional ACs.
- Operate steadily without any fluctuations
- Inverter ACs are inexpensive to run and less prone to breakdowns.
- Heat load depends on season, number of people, day/night aspect, and location climate profiles. Inverter is flexible to work in every situation, accordingly.
Let’s understand why inverter AC operating cost is low and it becomes a cheap option with an example.
Suppose you bought an inverter AC with a 1.5-ton capacity. When you switch the AC on its compressor runs at its fullest speed [say 150% rated speed] to cool the space rapidly till it reaches the set temperature.
Now, it cools down slowly [say 10% rated capacity] to a level sufficient for maintaining cool temperature as well as recompensing for heat that enters the room [opening and closing of doors]. It means this 1.5-ton inverter air conditioner will operate like 0.15-ton AC unit most of the time and as 2.25-ton unit in the start for rapid cooling.
The ability of changing its capacity as per the needs makes running cost of inverter AC units substantially low, so it is considered as the cheapest option.
