Abstract:
A defrosting system control method used in a direct-cooling refrigerator comprises steps of: starting a main refrigeration cycle system, a first switch apparatus (6) connecting a compressor (1) and a freezer (2), and a second switch apparatus (7) connecting the compressor (1) and a refrigeration evaporation pipe (5); determining, according to a frosting degree, whether to defrost; and if yes, starting a defrost temperature controller (11), so that the defrost temperature controller (11) switches the first switch apparatus (6) to connect the compressor (1) and a freezer evaporator (4), and switches the second switch apparatus (7) to connect the compressor (1) and a defrost refrigeration evaporating pipe (9), so as to start a defrost refrigeration cycle system. In the defrost control method, the first and second switch apparatuses (6, 7) are switched to implement switch between the main refrigeration cycle system and the defrost refrigeration cycle system, so as to implement automatic defrost of the freezer.
