In the hot summer, car air conditioners are our right-hand assistant when driving. Regular maintenance is essential to guarantee its efficient operation. This article will introduce you to the maintenance of car air conditioners.

Basic maintenance of car air conditioner

Basic maintenance of your car's air conditioner is key to ensuring the system operates efficiently, provides fresh air, and extends component life. Here are some basic car air conditioning maintenance methods:
① Replace the air conditioning filter:
Regularly changing your air conditioning filter is an essential step in maintaining clean air quality. Its function is that the filter stops dust, pollen and other particles from entering the car, while protecting the air conditioning system from impurities.
② Check the refrigerant level:
Check the refrigerant level regularly to make sure it is within the recommended range. If cooling effectiveness is reduced, refrigerant may need to be added. The effect is that adequate refrigerant levels help maintain the cooling performance of the system.
③ Clean the air conditioning drainage system:
Regularly inspect and clean the air conditioning drainage system to prevent water damage and mold growth. This can be done by cleaning the water drain lines. Its function is to clean the drainage system to prevent the accumulation of water stains, avoid odor and maintain the normal operation of the system.

④ Check and clean the condenser and evaporator
Check the condenser and evaporator regularly to make sure they are free of excessive dust or impurities. Its function is that clean condensers and evaporators help keep the system running efficiently and improve heat dissipation.
⑤ Make sure the pressure is normal
Regularly check the pressure of the refrigeration system to ensure it is within the normal range. Its function is that normal refrigeration system pressure helps avoid system failure and maintain the normal working condition of components.

By performing these basic maintenance steps regularly, we can ensure the normal operation of the car's air conditioning system, improve driving comfort, and extend the life of the system. If you're not sure how to perform certain maintenance tasks, it's best to consult a professional technician or seek help from a professional auto repair center.

Refrigerants in automobile air conditioners

The refrigerant in a car's air conditioning system is a key working element, playing a key role in regulating temperature and ensuring a comfortable driving environment. The following are the main functions of refrigerants:
① Absorbing and releasing heat: The refrigerant is responsible for circulating in the air conditioning system, absorbing the heat in the car, and then releasing the heat through the process of compression and expansion. This process allows the air conditioning system to lower the temperature inside the vehicle.
② Refrigeration effect: The flow state of the refrigerant enables the air conditioning system to provide cooling effect. It absorbs heat from the car and releases it in the condenser, thereby lowering the temperature inside the car.
③ Cycle process: The refrigerant undergoes a cycle of evaporation and condensation. In the evaporator, it changes from a liquid state to a gas, absorbing heat from the car's interior. Then, in the compressor, the refrigerant is compressed into a liquid and the heat released is removed through the condenser.
When the refrigerant has the following problems, it may need to be recycled and refilled:
① Refrigerant leakage:

Leaking refrigerants rank among the most frequently encountered issues. Leaks can occur at connections, pipes, seals, or other components of the air conditioning system.
Reasons for recycling and refilling: Leakage causes the refrigerant to decrease, affecting the cooling effect of the air conditioning system.

② Abnormal system pressure:
A low or high pressure condition in your air conditioning system may indicate abnormal refrigerant levels.
Reasons for recovery and refilling: Low pressure may indicate insufficient refrigerant, while high pressure may indicate excess refrigerant in the system.
③ Compressor failure:
Compressor failure may cause unusual noise or vibration.
Reasons for recycling and recharging: Compressor failure may cause abnormal circulation of refrigerant, requiring recycling, repair or replacement of refrigerant.
④ Odor and mold:
Not using your air conditioning system for an extended period of time can lead to odor and mold growth.
Reasons for recycling and refilling: Odors and mold may be due to moisture entering the system or refrigerant contamination. Recycling and recharging cleans the system and adds fresh refrigerant.
⑤ Regular maintenance:
As part of regular maintenance, refrigerant levels and the overall condition of the system need to be checked.
Reasons for recycling and filling: In order to ensure the long-term healthy operation of the system, regular recycling and filling are necessary.
⑥ Replace some components:
Recycling and refilling may be required after replacing certain key components of your air conditioning system (e.g. compressor, evaporator, etc.).
Reasons for recycling and recharging: After replacing components, it may be necessary to refill the refrigerant to ensure normal operation of the system.
Generally speaking, refrigerant recovery and recharging are usually to solve the problem of reduced cooling effect, system failure or maintenance needs to ensure the normal operation of the automobile air conditioning system.

Refrigerant recovery and filling equipment

Refrigerant recovery and filling equipment are specialized tools for handling refrigerants in automotive air conditioning systems, ensuring safety, efficiency and compliance with environmental regulations.

Today we introduce a car air conditioning refrigerant recycling and filling machine that integrates refrigerant recycling, vacuuming, filling and other functions.

AC519 is a fully automatic intelligent automobile air conditioning maintenance equipment newly launched by SmartSafe that integrates disassembly-free cleaning, refrigerant recovery, filling, vacuuming and other functions. It can effectively improve air conditioners with poor refrigeration effect and high compressor load. Problems such as loud noise and high fuel consumption.

① Equipped with automobile refrigerant model database, no manual setting is required.
② Supports two refrigerants: R134A or R134YF.
③ It has forward cleaning, reverse cleaning and pulse cleaning functions, and the cleaning effect is obvious.
④ The automatic mode can complete operations such as cleaning, recycling, vacuuming, filling refrigeration oil, and refrigerant with one click. Each function can also be executed independently.
⑤ Built-in printer supports printing materials, working hours and other information.
① Air conditioning pipeline cleaning:
Clean the air-conditioning pipelines to remove sludge, powder and other impurities inside the pipelines, replace the refrigeration oil more thoroughly, improve compressor lubrication, and improve the refrigeration performance of the air-conditioning system.
② Refrigerant recovery
The refrigerant in the automobile air conditioning system is purified and regenerated and then recycled into the working tank to meet the standards for reuse.
