The recommended temperature range for car air conditioning is 21-25°C in summer and 25-28°C in winter. These are the automotive comfort environment standards established by the industry, and the interior temperature should not differ too much from the external environment temperature. Precautions for using car air conditioning: Regularly replace filters: The air conditioning filter should be changed periodically. Dust and willow catkins can accumulate on the filter, which not only promotes bacterial growth but also causes musty odors in the AC system. It's advisable to replace the filter every year after spring. Additionally, the condenser should be cleaned regularly, and for thorough cleaning, the radiator should be removed. Temporarily turn off AC during heavy engine load: During hot seasons when the engine operates under heavy load for extended periods, it requires effective cooling. To prevent engine overheating, temporarily deactivate the air conditioning. Otherwise, engine overheating may affect both vehicle performance and AC operation. Select appropriate fan speed settings: During normal driving, to prevent excessive frost buildup on the evaporator that could impair AC system performance, avoid setting both fan speed and temperature controls to their lowest settings for prolonged periods. However, when driving below 25km/h, set the fan speed to low gear to prevent insufficient power generation and inadequate cooling.
