The time it takes for an air conditioner to cool down a room from 36 degrees Celsius to 26 degrees Celsius will depend on several factors, including the cooling capacity of the AC unit, the size of the room, insulation levels, and external environmental conditions. It's difficult to provide an exact estimate without specific details, but I can offer a general guideline.
A 5-star AC unit typically has a higher cooling capacity, which means it can cool a room faster than lower-rated units. However, cooling a room by 10 degrees Celsius (from 36 to 26 degrees Celsius) is a significant temperature difference and may take some time.
Under normal conditions, it could take approximately 30 minutes to a few hours for the AC to bring the temperature down to 26 degrees Celsius, assuming the AC is functioning properly and the room is properly insulated. However, it's important to note that the actual time can vary depending on the factors mentioned earlier.
Keep in mind that setting the cooling temperature to 16 degrees Celsius is quite low and may require the AC to work harder, increasing the cooling time and energy consumption. It's generally recommended to set the temperature to a comfortable level, usually around 22 to 24 degrees Celsius, to ensure efficient cooling and energy usage.
