*Ninaee Electrical and Engineering Pvt Ltd has design* of rooftop HVAC systems, for 52 ambient”, it  means the unit is designed to operate at an outdoor ambient temperature of 52 °C (not 52 °F). In very hot climates like parts of India or the  
What “52 °C Ambient” Means
The maximum outdoor temperature at which the rooftop unit can still deliver its rated cooling capacity.
The condenser, compressor, and refrigerant system are designed to handle this heat level.
Standard HVAC units are often rated at 46 °C ambient, but high-ambient models go up to 50–52 °C.
At very high temperatures:
Condenser pressure increases
Cooling capacity drops
Compressor load increases
So manufacturers design special high-ambient packages with:
Larger condenser coils
High-capacity condenser fans
Special compressor protection
