Removing and collecting fluorine from air conditioning units is an operation that requires professional skills. The following are the specific steps and precautions:
1、 Preliminary preparation
Before starting to disassemble and collect fluorine, the following preparations need to be made:
1. Tool preparation: Prepare the necessary tools, such as adjustable wrench, Allen wrench, screwdriver, insulating tape, etc.
2. Safety protection: Wear work clothes to avoid injury during disassembly.
3. Power off operation: Turn off the power to ensure safe operation.
4. Cleaning the site: Clean up the debris on site to ensure the cleanliness of the operating area.
2、 Operating Steps
The following are the specific steps for removing fluorine from air conditioning units:
1. Turn on the air conditioning: Turn on the air conditioning and adjust the temperature to the cooling state.
2. Find the valve of the external unit: Find the valve on the external unit of the air conditioner. Generally, there are two valves, one high-pressure valve (thin pipe) and one low-pressure valve (thick pipe).
3. Close valves: Close both valves to ensure that they are in a closed state.
4. Discharge refrigerant: Open the vent valve and allow the refrigerant to be discharged from the thin tube, while using a container to catch the discharged refrigerant.
5. Disassembling the connecting pipe: Use tools to disassemble the connecting pipe, and be careful not to use excessive force to avoid damaging the connecting pipe.
6. Fluorine collection: After disassembling the connecting pipe, use an Allen wrench to close the valve of the external unit, wait for a period of time, and let the refrigerant flow back to the external unit until the pressure gauge value becomes 0. At this point, fluorine collection is completed.
7. Disconnect the power supply: Disconnect the power supply to ensure safe operation.
8. Cleaning the site: Clean up the debris on site and ensure the cleanliness of the operating area.
3、 Precautions
The following precautions need to be taken during operation:
When turning on the air conditioner, close the doors and windows to avoid affecting the operation effect.
When finding the external valve, pay attention to the position and identification of the valve, and do not confuse the high-pressure valve with the low-pressure valve.
3. When closing the valve, ensure that the valve is fully closed to avoid refrigerant leakage.
4. When discharging refrigerant, be careful not to discharge the refrigerant into the environment to avoid polluting the environment. At the same time, it is also important to avoid splashing refrigerant onto the skin to avoid skin irritation and poisoning.
When disassembling the connecting pipe, pay attention to protecting the interface of the connecting pipe to avoid damaging the interface. At the same time, be careful not to drop tools inside the machine to avoid damaging internal parts.
6. When collecting fluoride, it is necessary to pay attention to the changes in the pressure gauge. If an abnormal change in the pressure gauge value is found or cannot be reduced to 0, it may be due to refrigerant leakage or damage to the connecting pipe interface. At this time, the operation should be stopped immediately and the problem should be checked.
7. When disconnecting the power supply, pay attention to safe operation to avoid electric shock accidents.
8. When cleaning the site, attention should be paid to cleaning up the debris and residual refrigerants in the operating area to avoid harm to the environment and human health. At the same time, it is also important to place and organize the tools and materials in order to facilitate their next use.
