The causes and solutions of ice blockage in the chiller

In industrial production, chillers are important cooling equipment. If ice blockage occurs during use, it will seriously affect refrigeration efficiency and production progress. So what are the reasons for ice blockage in the chiller? How can we solve this problem?

The ice blockage of the chiller is mainly due to excessive moisture in the refrigeration system, and the main source of moisture is the moisture in the motor insulation paper in the compressor; If the cooling speed of the coolant is too fast during the cooling process, it can cause water in the condenser or cooling pipeline to freeze and block; The failure of temperature or pressure sensors may also cause ice blockage in the chiller; The refrigerant continuously circulates, and the water in the refrigeration system gradually concentrates at the outlet of the capillary. When the temperature is low, the water will condense into ice and gradually increase, which to some extent can cause ice blockage in the capillary of the chiller. These are all possible causes of ice blockage in the chiller.

How to solve the problem of ice blockage during the use of the chiller? Because excessive moisture in the refrigeration system is the main cause of ice blockage in the chiller, it is necessary to dry the entire refrigeration system. There are two processing methods to choose from: 1. Use an oven to heat and dry the components of the chiller. Remove the compressor, condenser, evaporator, capillary, and other components from the refrigeration system, and then place them in the oven for heating and drying; 2. Use heating and secondary vacuum extraction methods to remove moisture from various components in the refrigeration system.

If the ice blockage problem of the chiller is caused by a malfunction of the temperature sensor or pressure sensor, it is recommended to contact the chiller manufacturer in a timely manner and send professional personnel for maintenance.
