What are the reasons for the car compressor working normally but not cooling?

Car air conditioning compressor is working normally but not cooling, the specific reasons are as follows: 1. Refrigerant issue: The reason why the car air conditioning is not cooling may be due to a problem with the refrigerant in the car air conditioning system. 2. Filter blockage: The filter screen is blocked, increasing the resistance to cooling, resulting in the car air conditioning not cooling. 3. Dryer saturation: There is a dryer in the car air conditioning refrigeration system, whose main task is to absorb moisture in the refrigerant and prevent excessive moisture in the refrigerant from reducing the cooling capacity. When the desiccant in the dryer is saturated, moisture cannot be filtered out in time, resulting in the inability to cool.

Can electric cars run air conditioning while charging?

Electric cars can run air conditioning while charging, but this practice is not recommended. Using the air conditioning during charging increases the internal charge load on the power battery pack of new energy electric vehicles, causing the battery pack to continue working before it is fully charged. This significantly accelerates the battery degradation of the power battery pack. Below are some precautions for charging electric cars: 1. Pay attention to the timing of charging: Charge when the remaining battery level is around 30%, and use the car only after it is fully charged. For battery maintenance, it is advisable to perform a deep charge and discharge once a month—discharge the battery to 20% and then fully charge it before use. 2. Charging environment: High temperatures in summer and rainy weather can pose threats to the safety of electric vehicle charging. After using the electric vehicle, wait for it to cool down before charging. Charging should ideally be done in a cool, dry, and well-ventilated area.

Does using natural air without AC consume fuel?

Using natural air without AC consumes less fuel. Here is a brief introduction to gasoline: 1. Basic information: Gasoline is a volatile, flammable hydrocarbon mixture liquid distilled and cracked from petroleum, used as fuel. It appears as a transparent liquid, is flammable, and has a distillation range of 30°C to 220°C. 2. Development background: In the mid-19th century, people did not yet recognize the importance of gasoline, as kerosene for lamps was widely used at the time. Petroleum refining then relied on simple distillation processes to separate components with different boiling points. Kerosene, with its higher boiling point, was safer for lamp use and became the primary product of crude oil refining, while gasoline and other components were often burned as fuel.
