　　What is the reason for the pressure increase in semiconductor chiller?

　　Firstly, semiconductor coolers mostly use refrigerants for cooling, which are organic molecules. Due to its small molecular size, once leaked, it will quickly spread, and the refrigeration cycle system of semiconductor coolers is precisely a relatively closed environment. If there is a leak in this environment, the refrigerant will flow repeatedly, causing the pressure of the semiconductor cooler to increase.

　　Secondly, the increase in pressure in the semiconductor cooler may also be caused by blockage of the refrigerant oil or return oil pipeline. If the filter screen and other parts of the condenser are not cleaned in a timely manner during the refrigeration process, it may cause inefficiency in the return oil pipeline, increase the working load of the compressor, and increase the pressure of the semiconductor cooler.

　　We should take corresponding solutions to address the above issues. Firstly, regularly check the equipment for leaks, and if necessary, perform air changes in the refrigeration cycle system to address the leakage points. Secondly, regularly clean and inspect the filter screen and other components of the condenser, replace or add oil in a timely manner to ensure smooth oil return and prevent oil contamination from blocking the oil return pipeline and filter screen, causing pressure increase in the semiconductor cooler.

　　In addition, there are other methods that can solve the problem in a timely manner when the pressure of the semiconductor cooler increases. For example, after the initial shutdown of the semiconductor cooler, wait for 10-20 seconds before turning on the power, and at this time, the compressor will not immediately reverse if there is a startup shock. If there is a pressure increase during the normal operation of the semiconductor cooler, it is necessary to check the exhaust volume of the compressor one by one to identify the cause of the fault, and then carry out corresponding maintenance and replacement after confirmation.

　　In summary, the pressure increase of semiconductor coolers is a common problem, but as long as we regularly inspect and maintain them, and solve the problem in a timely manner, we can effectively avoid the impact caused by this. At the same time, reasonable use and arrangement in daily use can better ensure the long-term stable operation of semiconductor coolers.
