\t\t\t\t\t\tThe phenomenon of ice jam in\u00a0low temperature chiller\u00a0system is mainly due to the excessive water in the refrigeration system. With the continuous circulation of refrigerants, the water in the refrigeration system gradually concentrates at the outlet of expansion valve. Because the outlet of expansion valve has the lowest temperature, the water turns into ice and the ice enlarges gradually. To a certain extent, the expansion valve will be completely blocked,\u00a0resulting that\u00a0the refrigerant can not be recycled, and the cold storage will not refrigerate. <\/p>\n

The phenomenon\u00a0of ice jam in low<\/strong> temperature<\/strong> K\u00e4ltesystem<\/strong><\/a> is normal in the initial stage. There is frost in the evaporator, heat dissipation of the condenser, stable operation of the unit, clear and stable movement of refrigerant in the evaporator. With the formation of ice jam, the air flow is\u00a0gradually weakened and intermittent. When the jam becomes\u00a0serious, the sound of air flow \u00a0completely disappears. The refrigerant cycle is\u00a0interrupted. And the condenser\u00a0is gradually cooled.
\nBecause of the blockage, the exhaust pressure rises.\u00a0The sound of the machine increases.\u00a0There is no refrigerant flowing into the evaporator.\u00a0The frost area decreases gradually.\u00a0The temperature increases gradually, and the temperature of the expansion valve rises together, so the ice begins to melt. At this time, the refrigerant begins to recycle again. After a period of time, ice blockage occurs again, forming a periodic phenomenon of through-blockage. <\/p>\n

Troubleshooting of Ice Block <\/p>\n

The ice jam failure of low temperature\u00a0chiller system is due to excessive moisture in the system, so the whole refrigeration system must be dried. There are two ways to deal with it: <\/p>\n

1. Heat and dry the components of the refrigerant system in a drying box. Remove\u00a0the compressor, condenser, evaporator, expansion valve and return pipe in the refrigerant system \u00a0from the cold storage and put\u00a0them\u00a0into the drying box for heating and drying. <\/p>\n

2. Remove the water content of each part of the refrigeration system by heating and secondary vacuum extraction. <\/p>","protected":false},"excerpt":{"rendered":"
