How to add air conditioning refrigerant

As the high temperature in summer continues, the frequency of use of air conditioners has increased significantly, and the problem of poor cooling effect of air conditioners has also appeared frequently. Among them, insufficient refrigerant is one of the common reasons that causes the cooling effect of air conditioners to decrease. This article will introduce in detail how to add refrigerant to the air conditioner, and attach the hot topics and hot content in the past 10 days to help you better understand the relevant knowledge and operation steps.

1. Hot topics and content in the past 10 days

2. The role of air conditioning refrigerant

Refrigerant is the key medium used to transfer heat in air conditioning systems. It transfers indoor heat to the outdoors through the process of evaporation and condensation, thereby achieving a cooling effect. If there is insufficient refrigerant, the cooling efficiency of the air conditioner will decrease significantly, and it may even cause damage to the compressor.

3. How to judge whether the air conditioner needs to add refrigerant

1.Refrigeration effect deteriorates: If the indoor temperature drops slowly or fails to reach the set temperature after the air conditioner is turned on, the refrigerant may be insufficient.

2.The air outlet temperature is high: Under normal circumstances, the temperature of the air conditioner outlet should be more than 10°C lower than the indoor temperature. If the temperature difference is small, there may be insufficient refrigerant.

3.Air conditioner freezes: Evaporator ice is one of the typical symptoms of insufficient refrigerant.

4.Abnormal noise: The compressor is overloaded due to insufficient refrigerant, which may produce abnormal noise.

4. Steps to add refrigerant

1.Preparation: Make sure the air conditioner is turned off and have the refrigerant tank, pressure gauge, charging tube and other tools ready.

2.Connect pressure gauge: Connect the pressure gauge to the low-pressure valve of the air conditioner, paying attention to distinguish the high-pressure and low-pressure interfaces.

3.Start the air conditioner: Set the air conditioner to cooling mode and turn on the maximum air volume.

4.Read pressure value: Observe the reading of the pressure gauge. Normal low pressure should be between 0.4-0.6MPa. If it is lower than this range, it means that refrigerant needs to be added.

5.Add refrigerant: Connect the refrigerant tank to the charging pipe, slowly open the valve, and let the refrigerant flow into the air conditioning system. Also observe the pressure gauge to ensure that the pressure is within the normal range.

6.Check the effect: After the addition is completed, close the refrigerant tank valve, disconnect, and check whether the air conditioning cooling effect returns to normal.

5. Things to note

1.Safety first: Be sure to wear protective gloves and glasses during operation to avoid refrigerant contact with skin or eyes.

2.Professional assistance: If you are not familiar with the air conditioning system, it is recommended to contact professional maintenance personnel for operation to avoid equipment damage or personal injury caused by improper operation.

3.environmental awareness: Refrigerant is a chemical substance, and random discharge will cause environmental pollution. Please dispose of waste refrigerant in accordance with relevant regulations.

6. Conclusion

Through the above steps, you can have a preliminary understanding of how to add refrigerant to the air conditioner. However, air conditioning systems are complex, and if you are unsure whether you are operating properly, it is recommended to seek professional help. Regular maintenance of your air conditioner not only improves your experience, but also extends the life of your equipment.
