    Abstract: PURPOSE:To perform delicate temperature regulation, in a freezer refrigerator to freeze, refrigerate, and store foods. CONSTITUTION:A temperature in chamber detecting means 22 is arranged to each of a freezing chamber and a refrigerating chamber to detect temperatures in respective chambers. A door opening closing detecting means 21 is provided to detect the door opening closing state of each chamber, and an open air temperature detecting means 42 is provided to detect an open air temperature. From temperature in a chamber, a door opening closing state, and an open air temperature, the decrease margin of a set temperature is operated by a first neutral network operating means 43 and a second neutral network operating means, and based on the operated results, a set temperature is operated by a set temperature operating means 44. Further, a compressor, a fan, and a motor-operated damper are controlled.

    Abstract: PURPOSE:To provide a controlling device for a refrigerated-cold storage cabinet which regulates the temperature of a refrigerating chamber to an optimum value when foods are packed to the full during a summer season and rapid cooling is to be effected when a user has unexpected visitors, in a freezer refrigerator provided with a refrigerating chamber in which foods can be refrigerated and stored. CONSTITUTION:A computing means 26 for an atmospheric temperature is provided and computes the degree of a change in an atmospheric temperature of a refrigerating chamber from a door opening time, an outside air temperature, and temperature in a cabinet. A computing means 28 for a load is provided and computes a load amount (a food temperature X heat capacity) of foods in the refrigerating chamber from temperature in the cabinet and a rate of change in temperature in the cabinet and further computes a fluctuation in a thermal load (an increased and a decrease in a thermal load amount). A fuzzy inference processor 30 performs fuzzy logic computation based on a thermal load amount, a fluctuation in a thermal load, the degree of a change in an atmospheric temperature, and a control rule taken out from a memory 29 and calculates the number of revolutions of a fan motor and the opening of a damper.

    Abstract: PURPOSE:To provide a quick cooling controller for a refrigerator, which is for cooling foods and the like to the optimum temperature within a short period of time and capable of achieving an objective temperature in a short period of time without deteriorating the quality of the foods or spoiling the taste and flavor of the foods due to the freezing of the foods. CONSTITUTION:The title device is constituted of a food temperature detecting means 27, detecting the temperature of foods in a chilling chamber, a first air temperature detecting means 35, detecting the temperature of air, a second air temperature detecting means 37, detecting the temperature of air, a differentiating means 28, outputting the amount of changing of a difference between the outputs of these two sets of air temperature detecting means, a memory means 31, storing a control rule based on an experience rule for obtaining the amounts of operations of a chilling fan 23 and a damper 31, and a fuzzy inference means 30, effecting fuzzy inference operation based on the control rule taken out of the memory device 31.
