    摘要: A defrosting controller for use with a refrigeration system determines calculating a frost melting period from the measurements of the evaporator temperature during defrosting by means of an evaporator temperature sensor, establishes a refrigerating operation rate which is the ratio of the period of the frost melting process to the (total) open period of an electronic motor-driven valve during the refrigeration, and then decides whether the next defrosting operation is to be skipped or not.
