Cooling Capacity - It is the amount of heat energy removed by the Air Conditioner from a space for a given time. The most commonly used unit for Cooling capacity is British Thermal Unit (BTU) per hour. In common parlance, the capacity of AC is indicated in ton. 1 ton (1 TR) is equivalent to 12,000 BTU.
Energy Efficiency Ratio (EER) EER is a ratio that indicates the cooling efficiency of an air-conditioner with respect to the power consumption. EER = Cooling Capacity (Watt) / Power Input(Watt).
Star Rating - Star rating is provided by Bureau of Energy Efficiency (BEE),an autonomous body under the Ministry of Power. It is a part of its energy labeling pro gramme. The objective of the pro-gramme is efficient use of energy & its conservation. As of now, the number of stars vary from 1 -5. Energy labeling is mandatory for Room Air Conditioners. Each star has a specified band of EER . The following table provides the details of the EER band corresponding to each star
Star Rating-- Minimum --EER Maximum EER
1 star ------------ 2.3 ------------ 2.49
2 star ------------ 2.5 ------------2.69
3 star ------------ 2.7 ------------ 2.89
4 star ------------ 2.9 ------------3.09
5 star ------------ 3.1 -----------***

The amount of heat is a function of many factors such as i) the location of your city ii) solar radiation heat through exposed roof, glass window etc, iii)No. Of people, electrical gadgets, in the room. Exact capacity can be determined by using the 'Heat Load calculation template'. However, as a rule of thumb , the following are the suggested area tonnage combination :
Area Of The Room (Sqf) -- Suggested AC Tonnage
Less Than 100 --------------------0.75 TR
100-130 ----------------------------1 TR
130 175 --------------------------- 1.5 TR
175 Upto 220 ---------------------2 TR
