What is the suitable temperature inside a car in winter?

[KalebAnn]

In winter, it is appropriate to set the car air conditioning between 18°C and 25°C; the most comfortable temperature for the human body is between 20°C and 25°C. Above 28°C, people will feel hot and stuffy; below 14°C, people will feel "cold." Therefore, the temperature inside the car should ideally be maintained between 18°C and 25°C. Components of car air conditioning: 1. Ventilation system: Its function is to ensure indoor ventilation while the car is in motion, continuously introducing fresh air and expelling dust, carbon dioxide, and harmful gases from the engine. In cold winters, the fresh air should also be heated to maintain a suitable indoor temperature. 2. Heating system: Its function is to heat the air inside the car or the fresh air entering from outside, providing warmth and dehumidification. 3. Cooling system: Its function is to lower the temperature inside the car when the external environment is hot, making passengers feel cool and comfortable. 4. Air purification system: Its function is to filter the incoming air, continuously removing polluted gases from the car and keeping the air inside clean.
