CONTROL METHOD OF INTER COOLER REFRIGERATOR

摘要

PURPOSE: A control method of an inter cooler refrigerator is provided to improve efficiency by letting a cooling force remaining in an evaporator into a refrigerating chamber. CONSTITUTION: A refrigerating chamber is cooled and reached to a normal state. A control unit(100) outputs a control signal to an output port(OP4) by a signal of a refrigerating chamber temperature sensor(92) and act a fourth relay(150). A channel switching valve(30) is acted so a coolant let out from a condenser as to face a second channel. The coolant is supercooled after passing through an inner pipe of an evaporator of the refrigerating chamber. The coolant lets in an evaporator of a freezing chamber passing through a second expansion device and cools the freezing chamber. Thereafter, the coolant returns to a compressor(10) passing through an outer pipe of the evaporator of the refrigerating chamber.
