What is the lowest temperature setting for car air conditioning?
1 Answers
Generally speaking, the lowest temperature setting for car air conditioning is around 10 degrees Celsius, and it also depends on the effectiveness of the car's air conditioning refrigerant. The cooling limit for most car air conditioning refrigerants is 10 degrees Celsius. The functions and usage recommendations of car air conditioning: The air conditioner can control the temperature inside the car, both heating and cooling the air to maintain a comfortable level. It can also remove humidity from the air. The ideal temperature setting for car air conditioning is between 18 to 25 degrees Celsius, with a temperature difference of no more than 10 degrees between the inside and outside of the car. The comfortable temperature range for the human body is 20 to 25 degrees Celsius. Above 28 degrees, people may feel hot, while below 14 degrees, they may feel cold. Car air conditioning engineers suggest setting the air conditioning to 21 to 25 degrees Celsius in summer and 25 to 28 degrees Celsius in winter. They also recommend that the temperature difference between the inside and outside of the car should not be too large to avoid discomfort for passengers. Typically, the temperature difference should be within 10 degrees for cars and 8 to 12 degrees for large buses. Classifications of car air conditioning: By throttling device and system structure: expansion valve refrigeration system, expansion tube refrigeration system. By driving method: non-independent air conditioning system, independent air conditioning system. By function: separate heating and cooling system, combined heating and cooling system, full-function system. By control method: manual air conditioning system, semi-automatic air conditioning system, fully automatic air conditioning system. By compressor displacement: fixed displacement air conditioning system, variable displacement air conditioning system.
