Evaporator frost thickening repair method from the working principle of constant temperature and humidity box, any type of refrigeration system may have frost phenomenon. The main factor is the humidity of the air in the constant temperature and humidity box and the moisture content of the food. When the frost layer inside the box is very thin, the effect on the heat transfer of the evaporator is not very obvious, but after the frost layer is gradually thickened and the entire evaporator is enveloped by frost, the heat transfer capacity of the evaporator will be seriously affected, and the box The internal temperature does not fall. It has been determined that when the frost thickness on the surface of the evaporator is greater than 10 mm, the heat transfer efficiency is reduced by about 30%, and the cooling efficiency is greatly reduced. In this case, defrosting is required. If there is a semi-automatic frost mechanism in the constant temperature and humidity box, the box door can be opened; press the defrost button and close the box door to allow it to automatically defrost. If there is no defrosting mechanism in the constant temperature and humidity chamber, it is necessary to cut off the power supply, and all the frost on the evaporator is melted before the power supply is cooled. Be careful not to hit the frost layer with wooden sticks or metal devices to prevent accidental ringing of the evaporator and unnecessary trouble. The current state-of-the-art constant temperature and humidity box is equipped with a timed automatic frost system. Defrosting automatically at selected intervals eliminates the need for user cleaning or buttons. The compressor will work automatically after defrosting. The water formed by the defrosting flows from the tank to the water storage box at the bottom of the constant temperature and humidity chamber through the diversion pipe, and is heated to automatically evaporate. Water storage trays should be washed once a month to maintain cleanliness and evaporation.
