In summers, the temperature goes to its peak and everything starts melting. As a result, we all look for a room with cool air to get a relaxing environment either in our homes or offices. When it comes to buying the air conditioner, the debate starts with inverter ac or non-inverter ac. Above all, everyone wants the most cost-effective, eco-friendly, and energy-efficient appliances. Therefore, we tried to clear your confusion by simply explaining the working of both inverter and non-inverter air conditioners. Keep reading to make a better decision about buying the best ac this summer.
Difference between inverter and non-inverter ac
An air conditioner with inverter technology is becoming the preferred one due to its energy efficiency and quieter operation. Let’s have a look at the working of both inverter and non-inverter air conditioners and how they are different from each other.
How a Non-Inverter ac works
A non-inverter air conditioner has a fixed-speed compressor motor. All compressor motors consume the most electricity at start-up. The compressor switches off when the desired room temperature is reached. However, it starts again when the temperature increases beyond the present threshold. As a result, the compressor will consume this high start-up electrical energy because of the repetitive ON-OFF process through each cycle. Thus, making them less energy efficient than their inverter counterparts. Also, the ambient/room temperature will also be going below and higher than the set temperature through each cycle.
How an Inverter ac works
An Inverter air conditioner has more than one rotation speed of the compressor. When the ac is switched on, the compressor operates at a high speed to cool the area rapidly. As room temperature approaches the desired temperature, the compressor slows down eventually to its lowest speed setting. Thus, slowly achieving the set temperature. During this period, the slower rotation speed of the compressor reduces the energy consumption. On the other hand, it significantly delays the compressor from turning off which eventually would need to be started up again needing the high start-up energy.
In short, for a billing cycle, the inverter air conditioner will use significantly less power. Hence, a significantly lower cost in comparison to a similar BTU capacity non-Inverter or conventional air conditioner.
Why an inverter ac is not working?
Despite the clear advantages of choosing an Inverter air conditioner, we must take into account that an inverter air conditioner will only perform optimally if:
- It is not under capacity, for example, a room-size needs a 2 Ton (24000 BTU/hr) unit. But, installing a smaller capacity unit will cause the compressor to run at its maximum rotation setting for a much longer time. As a result, making it consumes the same amount of energy as a non-Inverter air conditioner.
- The air conditioner is not used intermittently for short durations. In other words, turned on for half an hour or an hour and then turned off again. For an inverter air conditioner to go into a reduced speed compressor operation mode, it needs to run and reach the target room temperature and then maintain it. But, running it for short durations is equivalent to manually overriding the inverter. Hence, turning it off and on again converts it into a non-Inverter air conditioner. As a result, removing the advantage of reduced power consumption.
Hence, an added investment in an inverter air conditioner should only be made for a space where we need to run the air conditioner for at least 6 to 8 hours a day. So, if you want to purchase the best air conditioner then investing in a dc inverter is recommended by experts. In short, a one-time investment is far better than paying increased bills monthly.
