What is the normal pressure of automotive air conditioning refrigerant?

The pressure of automotive air conditioning refrigerant varies under different conditions: 1. When the compressor is running at 1500 to 2000 rpm, the high pressure is approximately 1.5 to 2.0 MPa, and the low pressure is around 0.15 to 0.35 MPa. 2. In idle conditions, if the ambient temperature is high and under direct sunlight, the high pressure may be slightly higher, reaching about 2.5 to 2.8 MPa, but it generally does not exceed 3.1 MPa. Under normal circumstances, cars do not need to add refrigerant for 3 to 5 years. However, sometimes if the cooling effect of the refrigerant is poor, it may need to be replenished. After the air conditioner has been running normally for a while, if the air blowing on you feels cool and quickly reaches the set temperature, and the outdoor compressor operates intermittently like a refrigerator, it indicates normal functioning. Otherwise, it might be necessary to add refrigerant.

What are the dangers of refueling without turning off the engine?

The hazards of refueling without turning off the engine: 1. When opening the fuel tank cap, fuel may spray out, creating a safety hazard; 2. The engine continues to run with current flowing, which can lead to short circuits or leakage, posing a significant fire risk; 3. The surrounding area of the car generates considerable heat. During refueling, the concentration of fuel vapor mixed with air around the tank increases. If a spark occurs while the vehicle is running, the gasoline molecules in the air can easily ignite, leading to danger. Precautions for refueling: 1. Do not use mobile phones; 2. No smoking; 3. Turn off the engine and power supply before refueling.

How to Tell if a Tire is a Tubeless Tire?

Methods to identify a tubeless tire: 1. Tubeless tires bear a unique marking, the TUBELESS logo. If present, it's a tubeless tire; otherwise, it's not. 2. If the wheel rim is of the spoke type, it's not a tubeless tire. 3. Tubeless tires have raised sections on their rubber; absence of these indicates it's not tubeless. Precautions for using tubeless tires: 1. Maintain the specified air pressure. Tubeless tires are made of high-quality rubber with good elasticity and flexibility, accommodating a wide range of pressures. Even at high pressure, they don't feel as hard as conventional tires, so always use a pressure gauge for checks. 2. Not suitable for overloading. Tubeless tires are wear-resistant but not pressure-resistant; they're unsuitable for excessive overloading.
