This standard specifies the constructional, performance, and safety requirements for room air conditioners of the vapour compression type, including both window and split units, up to a rated cooling capacity of 12 kW. It is fundamental for manufacturing, testing, and the BEE star labelling program in India, focusing on energy efficiency through ISEER.
Specifies requirements for the design, construction, performance, and testing of room air conditioners.
Quick Reference Values
Standard Indoor Test Temperature (Cooling)27°C Dry Bulb, 19°C Wet Bulb
Standard Outdoor Test Temperature (Cooling)35°C Dry Bulb, 24°C Wet Bulb
High Temperature Outdoor Test Condition46°C Dry Bulb
Voltage and Frequency Tolerance for Test±1% of rated value
Minimum Power Factor (>1000W input)0.90 lagging
Maximum Condensate Water Carry Over3% of total condensate
Key Formulas
EER = Q / P (where Q is Cooling Capacity in W, P is Power Input in W)
ISEER = CSTL / CSEL (where CSTL is Cooling Seasonal Total Load and CSEL is Cooling Seasonal Energy Consumption)
Practical Notes
This standard is integral to the mandatory BEE (Bureau of Energy Efficiency) Star Labelling Program for air conditioners; compliance is essential for market access.
The key performance metric is the Indian Seasonal Energy Efficiency Ratio (ISEER), which has replaced the older Energy Efficiency Ratio (EER) to better reflect real-world usage patterns.
Safety requirements are largely deferred to IS/IEC 60335-2-40, making it a critical companion document for ensuring product safety.
