Ease Inverter Split Air Conditioner, 5 Star

Details

The efficient one, and the page prints the arithmetic instead of the adjective. Rated cooling on the 1.5 ton is 5,275 W, measured to IS 1391 (Part 2) at the standard rating condition. One ton of refrigeration is 3,517 W, so that is exactly 1.50 ton. Tonnage inflation is the classic cheat here, and a unit sold as 1.5 ton that measures 4,200 W is 1.19 ton, so read the watts on the rating plate rather than the name on the box. Now the star. This unit is ISEER 5.2 and uses 720 units a year on the 1.5 ton over the 1,600 running hours the BEE label assumes. Our 3 star, which is the same machine with a smaller heat exchanger, is ISEER 3.9 and uses 960, because 5.2 divided by 3.9 is exactly four thirds. The difference is 240 units, or Rs 1,920 a year at Rs 8 a unit. The 1.5 ton costs Rs 9,000 more than the 3 star, so it repays in a little under five years; the 1 ton gap is Rs 7,000 against Rs 1,280 a year, which is five and a half; the 2 ton gap is Rs 11,000 against Rs 2,560, which is four and a third. Bigger unit, faster payback, because the saving scales with capacity while the price gap does not scale as fast. And the honest edge of it: below roughly 700 to 900 running hours a year, depending on tonnage, this never repays inside the machine's life and you should buy the 3 star instead.

• ISEER 5.2. Annual units 480 (1 ton), 720 (1.5 ton), 960 (2 ton) over 1,600 hours, so about Rs 3,840, Rs 5,760 and Rs 7,680 a season at Rs 8 a unit
• Rated cooling 3,517 W (12,000 BTU/h), 5,275 W (18,000) and 7,034 W (24,000), to IS 1391 (Part 2) at 35 C outdoor and 27 C dry bulb, 19 C wet bulb indoor. Exactly 1.00, 1.50 and 2.00 ton
• Condenser and evaporator tubes are copper with a 0.3 mm wall, and the interconnecting pipe kit in the box is copper. The fins are aluminium, as they are on every split air conditioner including the ones that print 100 percent copper, because a copper fin costs several times more and buys nothing. What copper buys is repair: a leaking copper tube is brazed on site, an aluminium micro channel coil is replaced whole
• Twin rotary inverter compressor, variable 15 to 90 Hz, R32 refrigerant at GWP 675 against 2,088 for R410A. R32 is mildly flammable and is a reason to have the unit handled by someone who knows it
• Installation is not included and we do not arrange it. A split has to be mounted, piped, vacuumed and gas checked by someone competent, which in most cities costs Rs 1,500 to Rs 2,500 for a standard fit, with core cutting, extra pipe, a stand and cabling on top. That is what installers charge, not a quotation from us
• The outdoor unit ships pre charged for a pipe run up to 5 m: 0.70 kg of R32 on the 1 ton, 1.05 kg on the 1.5 ton, 1.45 kg on the 2 ton. Beyond 5 m the installer adds about 20 g a metre
• An installation caused leak is not a manufacturing fault and is not covered. A badly flared joint is the commonest thing that goes wrong with a new split, and we would rather say so here than at the claim
• 32 dB(A) indoor on low, 42 dB(A) on high and 48 dB(A) outdoor, all at 1 m, all measured in a room with a background below 30 dB(A)
• Washable pre filter, front slide out, no cartridge to keep buying. Fault codes blinked on the indoor unit and published, so no dealer only diagnostic tool is needed
• Spares held 10 years at published prices, on a spares bank bought with the first production run, a ten year supply clause with the maker, and the moulding tooling held in our name. The compressor and the PCB are bought in, so those rest on the supply clause rather than on tooling, which is the honest distinction
• 2 years comprehensive on both units including one gas recharge if a factory joint leaks, 5 years separately on the PCB, 10 years on the inverter compressor, covering the compressor itself and not the gas, the labour or the piping
• The honest trade off is size. A star rating is mostly heat exchanger area, so this outdoor unit is 900 x 700 x 320 mm and 42 kg against 800 x 550 x 285 mm and 32 kg on the 3 star. Measure the ledge before you buy
• Left out: no ioniser, no UV lamp, no filter subscription, no sealed PCB potting, no dealer only diagnostic tool
• There is no Shuunnya service network. We send parts and publish the fault codes so any competent technician can work on the unit. We do not promise a turnaround, because we cannot keep one yet
