2. Steps for adding air conditioning liquid
1.Check if cooling fluid needs to be added
If the cooling effect of the air conditioner is significantly reduced, and the reasons such as filter clogging have been ruled out, it may be that the air-conditioning liquid is insufficient. It is recommended to use a pressure gauge to check the system pressure to confirm whether it needs to be replenished.
2.Prepare tools and materials
| Tools/Materials | Purpose |
|---|---|
| refrigerant tank | Replenish air-conditioning fluid |
| pressure gauge | Check system pressure |
| Connecting hose | Connect the air conditioner to the refrigerant tank |
| Gloves and goggles | Security protection |
3.Specific steps for adding cold air liquid
(1) Turn off the air conditioner power to ensure safety.
(2) Find the air conditioner low-pressure valve interface and connect the pressure gauge and hose.
(3) Open the refrigerant tank valve, slowly inject the cold liquid, and observe the pressure gauge reading.
(4) When the pressure reaches the normal range (usually 30-50psi), stop injection.
(5) Disconnect and start the air conditioner to test the cooling effect.
3. Precautions
1.Air conditioner liquid type: Be sure to use refrigerant that matches the air conditioner model. Common ones include R22, R410A, etc.
2.safe operation: Air conditioning liquid is a chemical substance. Protective equipment must be worn during operation to avoid direct contact with skin or eyes.
3.Leak check: If you need to add air-conditioning liquid frequently, there may be a leak in the system. It is recommended to contact a professional for repair.
4.Environmental requirements: Wasted refrigerants must be disposed of in accordance with regulations to avoid environmental pollution.
4. Risks added by DIY
Although adding your own cooling fluid can save money, improper operation may lead to the following problems:
| risk | Consequences |
|---|---|
| Excessive addition | Compressor damaged |
| Air mixed into the system | Cooling efficiency decreases |
| Leak not dealt with | Continuous loss of air conditioning fluid |
5. Professional advice
For most users, it is recommended to contact a professional air conditioning repairman to add air-conditioning fluid. Professionals can accurately determine the problem and use professional equipment to complete the operation to ensure long-term stable operation of the air conditioner.
