[QUOTE="avi, post: 2078578, member: 38834"] I have updated the OP. I did some calculations, for me 3 star also seems okay: Voltas 1.5 Ton 5 Star 185 CY - [URL]http://www.snapdeal.com/product/voltas-15-ton-5-star/754375241[/URL] Voltas 1.5 Ton 3 Star 183 CY - [URL]http://www.snapdeal.com/product/voltas-15-ton-3-star/229606840[/URL] Difference between them is 7000rs. Lets say my usage is daily 10 hours for 4 months an year. 3 star, 1555W: per day: 15.55 units per year: 1866 units (10 hours per day for 4 months) 5 star: 1424W: per day: 14.24 units per year: 1708 units (10 hours per day for 4 months) so difference each year is 158 units for 6rs per unit, you will save 948rs per year. ---- Some rough calculations on inverter also: Okay I am doing calculations around inverter and std ACs (5 star) I need 1.5ton Ac, so let's assume it's of 1500W making 1.5unit per hour. The initial difference is 10-12K for inverter and non inverter. And I am gonna run the Ac only for 4 months. Max 10 hours/day. Usually it's said that inervters save 30% of std ones. Std Ac: 1.5 unit/hour i.e. 450 units per month (each day 10 hours) For 4 months = 1800 units Inverter Ac: Let's assume it saves only 20% For 4 months = 80% of 1.8k = 1440 units The difference is 360 units. At 6rs unit I will save roughly 2k per year. So it will take me 5 years to get the inverter AC extra charges back and reap the benefits. Now let's assume, for the sake of it, that I am gonna use for 15 hours day Std ac: 1.5 unit/hour i.e. 675 units per month (each day 15 hours) For 4 months = 2700 For inverter For 4 Months = 2160 So difference is 540 units At 6rs unit I will save roughly 3k per year. So it will take 3 years to reap the benefits of AC Is my understanding, calculations are correct? Am I wrong anywhere? [/QUOTE]
