The freezing phenomenon of the refrigerated dryer is caused by the mismatch between the air volume processed by the air compressor and the refrigerated dryer, and the pressure is too low, resulting in the customer's production being unable to use the air normally. In case of ice blockage, stop the operation of the refrigerated dryer immediately. As the name implies, the freeze dryer is dry compressed air. Dry compressed air will wash away water. In the cold winter, the freezing of water will lead to the failure of the refrigerated dryer. How to solve the problem of ice blockage in the refrigerated dryer? Next, let's talk about it.
1. Water is introduced during the pressure test at atmospheric pressure. Air contains water, but the water content in different humidity is different. If the temperature in the cabinet and the temperature of the evaporator are relatively high and dry, the water in the compressed air is not easy to condense into water droplets, and when the water vapor is discharged from the system together with the water vapor, the water vapor will be discharged from the system together with the air. Evacuate. If the temperature of the cabinet is very low, that is, the temperature of the evaporator is very low (sometimes there is ice in the freezer during repair), the water introduced during pressurization will form water droplets or frosted pipes in the evaporator and adhere to the pipes. When time is taken out, the cream will not be discharged from the body. Only remove all ice from the refrigerator, and then use baking to raise the temperature of the evaporator. Used in conjunction with the addition of refrigerant, heat and bake for air treatment.
2. Due to the leakage of the evaporator, the refrigeration compressor will absorb water from the leakage when it is working. There is still water in the pipeline after the evaporator is repaired. Used in conjunction with the addition of refrigerant, heat and bake for air treatment.
3. Since the evaporator has a leak point, water will be drawn in from the leak point when the refrigeration compressor is working. These droplets are drawn into the refrigeration compressor. Because water is heavier than oil, these water droplets will sink into the bottom of the refrigeration compressor and be frozen. If the oil is sealed, it is difficult to evaporate all at once, which is an important cause of headache caused by stubborn ice cubes. Only operate the refrigeration compressor to generate heat, causing the temperature of the refrigerant oil to rise, and the water will slowly precipitate with the rotation of the rotor and the temperature rising refrigerant oil. Constantly drain and add refrigerant to test the machine. If there is ice block, please repeat the above steps until the ice block is eliminated.
