Say air conditioning is "three-point quality seven-point installation", this sentence can be seen that the correct installation of air-conditioning for the future use of air-conditioning is how important. However, in the winter, the long-settled air conditioner was reopened due to the sudden cooling of the winter, and many friends found that the air conditioning in the home was not a lack of heating or an abnormal operating phenomenon, especially in the southern cities. The usage rate is higher.
So today, the editor brings you a few safety precautions that you need to pay attention to in your use. In the winter, we must not only use health but also use safety.
One defense: Leakage of water in the air-conditioning cooling process, the chance of dripping within the opportunity, this is not the normal use of air conditioning, but due to the installation of air conditioning is not standardized, such as the internal machine installed than through the wall hole (tubes open to the outside The machine's place) is low, and the internal machine installation is not even.
â— Test method: After the air conditioner is installed, immediately test (cooling), if there is no water leakage for a certain period of time, there will be no water leakage problem. Of course, it is also possible to require installation personnel to perform leak testing and import water into the machine. The water flows through the machine's water tray and the downfall pipe naturally flows out of the room.
The second defense: leaking fluorine If the air conditioning joint is not tightened, cracked, etc., there will be fluoride leakage phenomenon. If the air-conditioning leaks fluorine, the user will need to replenish it frequently, and the normal use of air-conditioning generally does not require the addition of refrigerants for several years.
â— Inspection methods: The refrigerant leak check should be performed before the test machine. The leak detection is mainly for the four interfaces of the air-conditioning inside and outside the air-connected pipes and the shut-off valve ports. Soap water (or detergent can also be used) Leak detection is one of the methods commonly used at the scene. After opening the valve for split-type air conditioner for 10 to 15 seconds (cabinet for 20 to 30 seconds), the valve is closed. The various parts of the system are very Gas refrigerants with a pressure greater than 0.8 Mpa are quickly filled. Suspend suspicious spots and apply soapy water. If air bubbles form, there will be leakage. If no bubbles appear after 3 minutes of observation, it is considered as acceptable.
Three defenses: The regular installer of leakage current will check the power of the user before installing the air conditioner. If it does not meet the requirements, the user will be advised to change it. If the power cord does not meet the specifications and the air conditioner is installed, the phenomenon of electric leakage may occur and the user's personal safety may be endangered.
The “Specifications†requires that the connection between the power cord and the electrical control line of the air conditioner should be clear, accurate, and free of cross-winding; the air-conditioning must use a dedicated branch circuit, and the capacity must be greater than twice the maximum rated current value of the air conditioner; There is a dedicated power outlet, and it is a three-wire jack socket with a safety ground. The air-conditioner less than or equal to 4500W needs to use a 16A socket, and the air-conditioner larger than 4500W should use an air switch; the air-conditioner must have a good grounding and a grounding wire. It should be dedicated; the indoor and outdoor cables of the air conditioner should not be stretched, twisted, or twisted. The extension cord should use the wire that meets the requirements and be within the maximum connection length specified by the product.
Inspection method: See if the installer has the relevant power detection tool and check the power supply.
