Experts believe that the air conditioning in the car should be controlled at 20 to 24 degrees Celsius in summer, and the temperature difference between the inside and outside of the car should be maintained at 5 to 7 degrees Celsius.
On July 3, the Legislative Affairs Office of the State Council issued the "Regulations on Energy Conservation in Civil Buildings (Draft)" for public opinions, stipulating that the state implements an indoor temperature control system for public buildings that use air-conditioning for heating and cooling. Among them, the "indoor air-conditioning in summer shall not be lower than 26 degrees Celsius" regulations are expected to be determined in the form of legislation by the State Council.Although the "Regulations (Draft)" does not coverCar Air ConditionerTemperature control, but for the owners of more than 300,000 private cars in Shanghai, the use of appropriate air-conditioning temperature in summer is a good move for the country and the people.
Shanghai Sanden BehrcarHe Bin, director of the R&D department of an air-conditioning company, believed in an interview a few days ago that my country is the world's largest emitter of greenhouse gases, and the emissions of automobile exhaust and environmental pollutants are relatively serious. Therefore, driving one day less per person per month or controlling the car air conditioner at an appropriate temperature is to contribute to energy conservation and reduction of greenhouse gas emissions.
He Bin pointed out that in the hot summer season, the correct use and control of car air-conditioning temperature is very particular. First of all, if the temperature of the air conditioner in the car is too low or the temperature difference between the inside and outside of the car is too large, the blood vessels of the human bod

Shanghai Sanden BehrcarHe Bin, director of the R&D department of an air-conditioning company, believed in an interview a few days ago that my country is the world's largest emitter of greenhouse gases, and the emissions of automobile exhaust and environmental pollutants are relatively serious. Therefore, driving one day less per person per month or controlling the car air conditioner at an appropriate temperature is to contribute to energy conservation and reduction of greenhouse gas emissions.
He Bin pointed out that in the hot summer season, the correct use and control of car air-conditioning temperature is very particular. First of all, if the temperature of the air conditioner in the car is too low or the temperature difference between the inside and outside of the car is too large, the blood vessels of the human body will suddenly contract, causing the blood flow in the body to slow down and the heart's blood supply is insufficient. If things go on like this, it may cause complications. Similarly, the lower the temperature of the air conditioner in the car, the more fuel it consumes, and the greater the loss of air conditioners and related components, the cost of using the car will increase significantly. Therefore, under normal circumstances, the air conditioning in the car should be controlled at 20 to 24 degrees Celsius in summer, and the temperature difference between the inside and outside of the car should be maintained at 5 to 7 degrees Celsius.
Secondly, the vehicle is "exposed" by the sun when it is parked, and the inside of the vehicle is like a steamer with a temperature of at least 50 degrees Celsius. At this time, you should first open the window and door to start the external circulation of the air conditioner to exhaust the hot air in the car. Wait for the hot air to dissipate before turning on the air conditioner, but do not close the windows first, and close the windows to open the internal circulation after the cool air blows out from the air outlet of the air conditioner. This can avoid the increase of engine load and save fuel. According to the principle of sinking cold air and rising hot air, when turning on the air-conditioning in summer, turn the air outlet upward and use the car air conditioner in a fully enclosed state. If the windows are not closed tightly, not only the cooling effect is not good, but also fuel is wasted.
Again, long-term use of the air conditioner will makeCondenserThe pressure is too high, causing losses to the refrigeration system. Therefore, each time you use the air conditioner should not be too long.If the car has reached a comfortable temperature, you can turn off the air conditioner and turn it on again after a while; when parking, do not turn off the power directly to leave, you should turn off the air conditioner firstswitch, Let the ventilation system run for 1 minute, which is definitely beneficial to the maintenance of the air conditioning system.
He Bin finally reminded owners of cars that, according to a sample survey, about 50% of drivers do not operate the air-conditioning system correctly. Therefore, in consideration of physical health and driving safety, it is necessary to master basic knowledge of air-conditioning use and overcome bad operating habits. This is not only conducive to vehicle maintenance and reducing vehicle costs, but also conducive to the optimization of environmental protection in the whole society.
