Common fuel cell environmental test device inspection method

During the cooling process of the fuel cell environmental test device, there is a chance of dripping inside. This is not a normal phenomenon used by the fuel cell environmental test device, but is caused by improper installation. After the fuel cell environmental test device is installed, test the machine (refrigeration) immediately. If there is no water leakage after running for a certain period of time, there will be no leakage problem. Of course, the installer can also be required to carry out the water leakage test, and the water is introduced into the internal machine, and the water naturally flows out of the outdoor water through the water receiving tray and the down pipe.

The fuel cell environmental test device will emit a certain amount of noise, but if the noise is too large, it may be caused by improper installation. During the installation, the inner wall panel is not nailed, and the inner machine is not fixedly dead, which may easily lead to excessive noise. In this case, the installer can easily find and correct the problem by testing the machine.

The installation position of the fuel cell environmental test device is also very particular. It is not where the user likes to install it. Otherwise, it will lead to maintenance troubles and poor cooling effect. The households should avoid heavy oil smoke, wind and sand, direct sunlight and heat dissipation. Where there is a poor or high-temperature heat source, it is also necessary to avoid hidden dangers such as flammable gas leaking easily, strong corrosive gas, artificial strong electricity or direct magnetic field action.

If the joint of the fuel cell environmental test device is not tightened, cracked, etc., fluorine leakage may occur. If fluorine is leaking, the user should always replenish it. The normal use of the fuel cell environmental test device generally does not require the addition of refrigerant for several years. The refrigerant leak check should be performed before the test machine. The leak detection is mainly for the four interfaces of the internal and external connecting pipes of the household fuel cell environmental test device and the valve port of the shut-off valve. Soap water (you can also use detergent) leak detection is one of the commonly used methods in the field. After opening the valve for 10 to 15 seconds (the cabinet is 20 to 30 seconds), the valve is closed, and the parts in the system are quickly filled more than A gaseous refrigerant with an air pressure of 0.8 MPa. Apply soapy water to the suspicious point of the leak. If there is a bubble, it will leak. If it is observed for 3 minutes, no bubbles will appear.

The regular installer will check the user’s power supply before installing the fuel cell environmental test device. If the requirements are not met, the user is advised to change it. The power cord is not installed in accordance with the specifications, and it is prone to leakage and fire, which endangers the user’s personal safety. The installer is required to test the power supply with the associated power detection tool.

Since the fuel cell environmental test device has a certain requirement in the fuel cell test, the above faults are avoided as much as possible.
