How to put refrigerant in car
With the arrival of high temperatures in summer, the frequency of use of car air conditioners has increased significantly, and the addition and replacement of refrigerant (refrigerant) has become a hot topic for car owners. This article will introduce in detail the correct method of adding car refrigerant, and provide you with a practical guide based on hot topics on the Internet in the past 10 days.
1. What is automobile refrigerant?
Automobile refrigerant, that is, automobile air conditioning refrigerant, is the key medium used for refrigeration in the air conditioning system. Common refrigerant types include R134a and R1234yf. The refrigerant types used by different models may be different and need to be selected according to the vehicle manual.
2. Steps to add car refrigerant
The following are the detailed steps for adding car refrigerant:
| steps | Operation content | Things to note |
|---|---|---|
| 1 | Check air conditioning system pressure | Use a pressure gauge to check whether the high and low pressures are normal |
| 2 | Connect the refrigerant tank | Make sure connections are sealed to avoid leaks |
| 3 | Start the air conditioner and add refrigerant | Keep the engine running and turn the air conditioner to maximum |
| 4 | Observe the pressure gauge | Stop adding after the pressure reaches the standard value |
| 5 | Disconnect and check | Make sure there are no leaks and the air conditioning cooling effect is normal |
3. Hot topics in the past 10 days and discussions related to automobile refrigerants
According to the search data on the entire Internet, the following are the recent hot topics related to automobile refrigerant types:
| topic | Discussion popularity | Main point |
|---|---|---|
| Is it feasible to add refrigerant by DIY? | high | Some car owners think DIY saves money, but they need to pay attention to safety |
| The difference between R134a and R1234yf | in | Environmental protection and compatibility are the focus of discussion |
| Common causes of refrigerant leaks | high | Pipeline aging and seal damage are the main reasons |
| Solutions for air conditioners that don’t cool in summer | extremely high | Insufficient refrigerant and compressor failure are common problems |
4. Common misunderstandings about adding refrigerant types
When adding refrigerant, car owners often fall into the following misunderstandings:
1.Excessive addition of refrigerant: It is believed that the more added, the better the refrigeration effect. In fact, too much will cause the system pressure to be too high and damage the compressor.
2.Ignoring leak checks: Failure to check the system for leaks before adding refrigerant, resulting in rapid loss of refrigerant.
3.Use inferior refrigerant: Low-priced refrigerants may contain impurities, which may affect the life of the air conditioning system.
5. Professional advice
For car owners who do not have professional knowledge, it is recommended to go to a regular repair shop to add refrigerant. The following are reference criteria for choosing a repair shop:
| Project | Standard |
|---|---|
| Qualification | Qualified for car air conditioning repair |
| Equipment | Use professional pressure gauges and recovery machines |
| Refrigerant type | Provide refrigerant types suitable for car models |
| service | Provide leak detection and system inspections |
6. Summary
The correct addition of automobile refrigerant is the key to ensuring the cooling effect of air conditioning. Through the structured data in this article, you can clearly understand the steps, common misunderstandings and professional suggestions for adding refrigerant. Under high temperatures in summer, regularly checking the air conditioning system and adding refrigerant in a timely manner can make your driving experience more comfortable.
