1. Close the valve: First close the valve connected to the thermal expansion valve to ensure that no refrigerant leaks during the replacement process.
2. Disassemble the old thermal expansion valve: Use appropriate tools to disassemble the old thermal expansion valve.
3. Install a new thermal expansion valve: Install the new thermal expansion valve into the system. During the installation process, make sure that the model and specifications of the new thermal expansion valve are the same as the original one, and make sure that the installation position is correct for subsequent maintenance and care.
4. Detect leakage: After the installation is completed, perform a leak detection to ensure that the new thermal expansion valve has no leakage, thereby ensuring the normal operation of the entire air conditioning system.
5. Open the valve: Finally, open the valve connected to the thermal expansion valve to restore the system to normal operation. At this point, the entire replacement process is complete.
1. Regular inspection: Regularly inspect the thermal expansion valve, including checking whether the flow and pressure of the refrigerant are normal, whether the valve is flexible to open and close, etc.
2. Cleaning: Regularly clean the impurities and dirt around the thermal expansion valve to ensure the normal operation of the expansion valve.
