What causes the insufficient cooling of the Baojun 730 air conditioner?

[MacHazel]

It is usually due to a lack of refrigerant or a clogged air filter. Here are the relevant explanations: 1. Refrigerant: Refrigerant, commonly known as Freon, is the working fluid used in refrigeration and air conditioning systems to transfer heat energy and produce a cooling effect. Based on the working method, it can be classified as primary refrigerant or secondary refrigerant. Based on material properties, it can be categorized as natural refrigerant or synthetic refrigerant. 2. Car Air Conditioning: The car air conditioning device (air-conditioning-device), referred to as car air conditioning, is used to adjust and control the temperature, humidity, air cleanliness, and air flow inside the car cabin to the optimal state. It provides a comfortable riding environment for passengers, reduces travel fatigue, and creates good working conditions for the driver, playing an important role in ensuring safe driving as a ventilation device.
