Here's an AC that thinks and adjusts according to your needs. Blue Star's Inverter AC. Its compressor changes frequency according to the ambient load. As the frequency changes, RPM of the compressor also changes. This eliminates any temperature fluctuations and helps maintain a comfortable temperature. For example, a 1.5 TR Inverter AC can decrease its capacity of 1.5 TR and can go as low 0.25 TR , as per the requirement. As there is no cut in and cut off, the Inverter AC saves up to 30% more power.
The Inverter AC comes with a special heat pump that is useful during severe winters. What's more, this AC uses the latest environment-friendly refrigerant, R410A, that has almost nil ozone depleting substances. So, the AC is healthy for the environment too.
