Abstract

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of driving a refrigerator using heat storage cooling in a cold storage refrigerator. In the related art, since the method has been achieved by a time zone driving method or a timer driving for using late night power, it is possible to actively use a refrigerator using a storage coolant. It is hard to expect. The present invention is to allow the coolant to be operated in the refrigerator regardless of the use of late-night power in the refrigerator having a freezing fan and a refrigeration fan to improve the conventional problems, which is the microcomputer 40 of the freezer and the freezer Checking whether the operating temperature of the freezer compartment and the refrigerating compartment by comparing the temperature with the reference value, respectively (step 101,109,102,110), and checking whether the freezer compartment is a heat storage condition when the freezer compartment temperature condition is not determined through the step of checking the freezer compartment temperature condition (step 103). A step of checking whether the coolant heat dissipation condition is applied if the freezer compartment is on (step 104); and if the heat storage condition is not the above, the compressor and the refrigeration fan are turned off (step 105). (Step 106) and the refrigeration fan is driven if the coolant heat dissipation condition (step 108), otherwise the compressor and the refrigeration fan (Step 107), and if the system is not in the fridge operating on condition, turning off the fridge fan (step 113) and checking whether the coolant heat dissipation condition is in the fridge room condition (step 111), where the heat dissipation condition The present invention provides a cooling cycle control method for a refrigeration type two solenoid valve direct connection refrigerator, which comprises driving a refrigeration fan (step 112) or keeping the refrigeration fan in a hop state.

Claims (2)

In a method of controlling a refrigerator using accumulating heat in a refrigerated refrigerator including a compressor, a freezing fan, a coolant, a coolant for cooling, a microcomputer, and the like, the microcomputer 40 compares the temperatures of the freezer compartment and the freezer compartment with reference values respectively. And checking whether the refrigerating chamber is in an operating on condition (step 101,109,102,110), and checking the freezer compartment when the freezer is in a freezer storage condition when the freezer is in a freezer temperature condition (stem 103). Checking whether the condition is applied (step 104), turning off the compressor and the freezing fan when the heat storage coolant is not in the heat storage condition (step 105), and turning off the freezing fan only when the heat storage condition is obtained (step 106); Driving the refrigeration fan (step 108) if the coolant heat dissipation condition (step 108) or driving the compressor and the refrigeration fan (step 107); If the refrigerator is in a non-operating condition, turn off the refrigeration fan (step 113). If the refrigerator is in a cold condition, check whether the coolant heat dissipation condition is satisfied (step 111). A method of controlling the cooling cycle of a refrigeration type 2 evaporator direct-attached refrigerator comprising the steps of keeping the refrigeration fan off. The method of claim 1, wherein the cooling cycle control method comprises the steps of checking whether the microcomputer 40 compares the temperatures of the freezer compartment and the freezer compartment with reference values, respectively, to determine whether the freezer compartment is in an on condition (steps 101 and 102). If the freezer is not in the on-temperature condition, the compressor is turned off and the compressor is operated (steps 103, 104). If the coolant is in the heat storage condition, the refrigeration fan is checked. After the operation is turned off and the coolant heat dissipation condition is checked again, turning on the refrigeration fan (step 105, 106, 107) when the coolant heat dissipation condition is detected, and checking the refrigerating heat storage condition if the coolant operating temperature is detected. Or operating the refrigeration fans (steps 109, 110, 113), and the coolant heat dissipation tank if the coolant heat storage conditions are not the above. Checking the application and turning off the refrigeration fan under the heat storage condition of the coolant (step 111); driving the refrigeration fan under the heat storage condition of the coolant (step 112); or turning off the refrigeration fan. Cooling cycle control method of the refrigeration type 2 evaporator direct-attached refrigerator. ※ Note: The disclosure is based on the initial application.
