The invention discloses an
air cooling refrigerator
defrosting method. The
air cooling refrigerator
defrosting method includes the following steps that: first step, after accumulative
operating time of a compressor achieves a set value, the method enters a second step; second step,
defrosting preparation is performed; third step, after the temperature of a
freezing chamber drops TLD degrees, an
electric control device of the refrigerator judges whether THS is smaller than TDFTE-3 degrees in a
refrigeration process of the
freezing chamber, when THS<=TDFTE-3 degrees, the second step is terminated, and the method enters a fourth step; and fourth step, defrosting is performed, the defrosting specifically includes the following steps that: the
electric control device controls the compressor and makes the same stop working, and then, starts up a freezing defrosting heating tube to heat an
evaporator, and turns off the freezing defrosting heater when a freezing defrosting
electric heating condition quitting condition is satisfied, and the
electric control device control makes the compressor stop for 6 minutes, and then, the
air cooling refrigerator defrosting method is terminated, a normal startup-shutdown control program is initiated. According to the air cooling refrigerator defrosting method of the invention, an optimized control method is utilized to perform fine adjustment on a defrosting process, and therefore,
energy consumption increase caused by frequent defrosting of the refrigerator can be avoided, and condensed
frost can be melt completely.
