Tick Rating

The Tick Rating is defined as follows:

Air-conditioners

Type	COP _100%¹ (W / W)
No. of Ticks	0	1	2	3	4
Casement, window, single-split (non-inverter)	COP_100% < 2.5	2.78 > COP_100% > 2.5	3.2 > COP_100% > 2.78	COP_100% > 3.2	N/A
Multi-split (non-inverter)	COP_100% < 2.64	2.92 > COP_100% > 2.64	3.34 > COP_100% > 2.92	COP_100% > 3.34	N/A
Split type (inverter)² COP_100% Weighted COP ³	N/A Weighted COP < 2.64	N/A 2.92 > Weighted COP > 2.64	N/A 3.34 > Weighted COP > 2.92	COP_100% > 3.06 Weighted COP > 3.34	COP_100% > 3.34 Weighted COP > 3.76

¹ COP _100% is defined as the ratio of total cooling capacity to effective power input at full load cooling capacity
² For split (inverter) type air-conditioners, the model shall meet both the minimum COP _100% and weighted COP
³ Weighted COP = 0.4 x COP _100%+ 0.6 x COP _50%

Refrigerators

Type	Annual Energy Consumption (AEC) in kWh
No. of Ticks	0	1	2	3	4
Without freezer	AEC > (368 + 0.892 x V_{adj tot}⁴)	[(368 + 0.892 x V_{adj tot}) x 0.86] < AEC < (368 + 0.892 x V adj tot)	[(368 + 0.892 x V_{adj tot}) x 0.74] < AEC < [(368 + 0.892 x V adj tot) x 0.86]	[(368 + 0.892 x V_{adj tot}) x 0.64] < AEC < [(368 + 0.892 x V_{adj tot}) x 0.74]	AEC < [(368 + 0.892 x V_{adj tot}) x 0.64]
With freezer	AEC > (465 + 1.378 x V_{adj tot})	[(465 + 1.378 x V_{adj tot}) x 0.77] < AEC < (465 + 1.378 x V_{adj tot})	[(465 + 1.378 x V_{adj tot}) x 0.593] < AEC < [(465 + 1.378 x V_{adj tot}) x 0.77]	[(465 + 1.378 x V_{adj tot}) x 0.457] < AEC < [(465 + 1.378 x V_{adj tot}) x 0.593]	AEC < [(465 + 1.378 x V_{adj tot}) x 0.457]
With freezer , through-the - door ice dispenser ⁵	AEC > (585 + 1.378 x V_{adj tot})	[(585 + 1.378 x V_{adj tot}) x 0.77] < AEC < (585 + 1.378 x V_{adj tot})	[(585 + 1.378 x V_{adj tot}) x 0.593] < AEC < [(585 + 1.378 x V_{adj tot}) x 0.77]	[(585 + 1.378 x V_{adj tot}) x 0.457] < AEC < [(585 + 1.378 x V_{adj tot}) x 0.593]	AEC < [(585 + 1.378 x V_{adj tot}) x 0.457]

⁴ V_{adj tot}is defined here

⁵ 'Through-the-door ice dispenser' means an automatic ice maker coupled with a device that deliveries ice on demand externally through a door

Clothes Dryer

Type	Energy Consumption (EC) per wash in kWh
No. of Ticks	0	1	2	3	4
All clothes dryers	EC > [Rated Capacity⁶ ]	[Rated Capacity x 0.83] < EC < [Rated Capacity]	[Rated Capacity x 0.67] < EC < [Rated Capacity x 0.83]	[Rated Capacity x 0.50] < EC < [Rated Capacity x 0.67]	EC < [Rated Capacity x 0.50]

⁶ Rated Capacity means the mass in kilograms of a particular type of dry textiles which, according to the instructions of the manufacturer of the clothes dryer, can be treated in a particular drying programme suitable for drying the particular type of dry textile.
