The thermal expansion valve in the central air-conditioning unit is a key component that can adjust the refrigerant flow to ensure the normal operation of the system. When a failure occurs, it will affect the cooling effect and increase energy consumption. The causes of failure of the thermal expansion valve include blockage, air leakage and spring failure. The replacement steps include closing the valve, removing the old valve, installing the new valve, detecting leaks and opening the valve. Maintenance methods include regular inspection and cleaning.
The central air-conditioning unit is an important refrigeration equipment in modern buildings, and the thermal expansion valve is one of the key components in the central air-conditioning unit. The thermal expansion valve can automatically adjust the flow of refrigerant according to the needs of the system to ensure the normal operation of the system. However, when the thermal expansion valve fails, it will not only affect the cooling effect of the central air-conditioning unit, but also increase the energy consumption of the equipment. Yuxin Air Conditioning will explore the failure replacement and maintenance methods of the thermal expansion valve of the central air-conditioning unit.
The thermal expansion valve is an important component of the central air-conditioning unit. Its main function is to control the flow and pressure of the refrigerant. During the refrigeration process, the thermal expansion valve can automatically adjust the flow of refrigerant according to the needs of the system to ensure the normal operation of the system.
1. Blockage: Impurities and particulate matter in the system may block the thermal expansion valve, causing the refrigerant to not flow normally.
2. Leakage: The seal of the thermal expansion valve may leak, causing refrigerant leakage and affecting the refrigeration effect.
3. Spring failure: The spring of the thermal expansion valve may fail, causing the valve to fail to open and close normally.
