In hot summer, most people turn on the air conditioner when driving. We often hear car owners say "my XX car has good air conditioning" and "my XX car has cold air conditioning" and so on. So, you all want to know whether the air conditioning and refrigeration performance of your car is good or bad in the same class? To be honest, we are also very interested in this. To this end, this time, a big test of air-to-sound comparison was planned. We will choose several models of different factions in a checkpoint and compete on the spot to see who has better air sound.

The test method is simple. We exposed the assembled vehicle to the sun for 30 minutes and recorded the temperature of the compartment. Then immediately start the vehicle to turn on the empty sound, start the refrigeration 10 minute at the lowest temperature and the maximum air volume, then record the temperature of the carriage, and finally get the result. In the process of testing, in order to ensure fairness as much as possible, we will also have some special arrangements and testing steps, which will be introduced in detail below.

The first batch of A-class cars with the highest market share were tested. We have selected FAW-Volkswagen Golf, Shanghai GM Buick Hideo XT, Dongfeng Honda Civic, Saicmg6, Dongfeng Citroen Sega sedan and Beijing Hyundai Elantra as representatives, covering independent brands in Europe, America, Japan, South Korea and France, so that everyone can have a chance to see the empty performances of various factions. Because the air conditioning system test mainly tests the refrigeration capacity of each air conditioning compressor, we allow the engine displacement and power of different models to be different.

Ok, the rules of the game and the players are well understood. Let's get down to business.

Thanks to the following units for their strong support in providing test vehicles: Beijing Hyundai Elantra: Shenzhen Shunheying 4S Store FAW-Volkswagen Golf: Shenzhen Longteng 4S Store Dongfeng Honda Civic: Shenzhen Cheyou 4S Store Dongfeng Citroen Sega: Shenzhen Yanxing Penglong 4S Store.
