Cleaning and maintenance: * step, which is to clean the appearance. Simply rinse with ordinary water or use soapy water, and remember not to use corrosive liquids. And the ground around and at the bottom of the box should also be kept clean. The exterior of the box should be cleaned at least once a year to minimize dust. The second step is to clean the interior of the constant temperature and humidity testing machine workshop. Before operating the constant temperature and humidity testing machine, the internal impurities and distribution room should be cleaned at least once a year to avoid dust in the air from adhering to the machine surface or accessories such as condensers and evaporators. After cleaning, the body should be dried and kept dry. The front is the cleaning of the inside and outside of the body. As the core components of the constant temperature and humidity testing machine, such as the condenser, copper tube, evaporator, compressor, etc., the refrigeration system should be regularly cleaned, and dust should be collected in a timely manner.
