Summer has come. Most people who often drive will clean the car air conditioner before summer, but some people don't pay attention to the cleaning of car air conditioner, or even don't clean it for a long time. So what are the benefits of cleaning the car air conditioner? What's the harm of not cleaning the car air conditioner? What should we pay attention to when using automobile air conditioner in summer? This article brings you the benefits of car air conditioning cleaning, the harm of not cleaning and the precautions for using car air conditioning in summer.
Benefits of car air conditioning cleaning
1. Enhanced refrigeration.
After cleaning with special cleaning agent, the air conditioner is free of dust and scale, the air exchange is smooth, and the refrigeration effect is significantly enhanced.
2. Good for health.
After cleaning with special cleaning agent, it not only greatly reduces the incidence of 'air conditioning syndrome', but also purifies the indoor air and removes the strange smell produced by air conditioning.
3. Extend the service life of air conditioner.
After cleaning with special cleaning agent, the working environment of the air conditioner is changed, the service life of the air conditioner is prolonged, and the air conditioner itself is as clean as new.
4. Reduce power consumption.
After cleaning, the air conditioning environment is changed, the work efficiency is improved, and the power consumption is reduced.
5. Reduce expenses.
After cleaning and maintenance, the failure rate of the air conditioner is reduced, the power consumption is reduced, and the oil cost is virtually saved.
Harm of not cleaning automobile air conditioner
1. A large amount of return and dirt accumulated on the surface of filter plate, radiator, evaporator and fin, resulting in airflow blockage;
2. As a result, the cooling and heating effects are reduced, and the power consumption and noise are increased;
3. Reduce the service life of air conditioner;
4. Produce peculiar smell, breed bacteria and mites, and endanger people's health.
Precautions for using automobile air conditioner in summer:
1. When starting up, first turn on the blower switch, and then turn on a / C (compressor switch); When shutting down, first turn off the A / C switch, and then turn off the blower switch.
2. The temperature in the car should not be adjusted too low. Too low temperature will affect your health. Generally, the temperature of the air outlet in the car can be controlled at about 8 ~ 10 degrees.
3. In case of traffic jam, low-speed driving or parking, try to turn off the A / C switch of the air conditioner in order to prevent the engine from running at a high speed for a long time, resulting in too high temperature, so as to protect the engine
4. Control the air outlet direction. When the air conditioner is turned on, blow the air outlet upward. When the heating is turned on, blow the air outlet downward. It is based on the principle of cold air sinking and hot air rising according to physical phenomena.
5. When the air conditioner is turned on, first use the external circulation, so that the blower will suck the fresh air outside the vehicle into the vehicle to form air pressure and discharge the turbid air inside the vehicle. When the temperature drops, switch to the internal circulation mode, so that the refrigeration effect is the best, but the internal circulation mode cannot be used for a long time to avoid affecting the air quality in the vehicle.
