Abstract: PURPOSE:To prevent a refrigerator having an electrical charger troubled from being used and further prevent deterioration in quantity of a transported item by a method wherein the trouble of the electrical charger is detected and informed. CONSTITUTION:A timer means 53 transmits a signal to a informing output means 54 after an optional time from a turning-ON of a commercial power supply in response to a power supply input discrimination means 43. Informing output means 54 informs that an electrical charger 45 is troubled when a signal is sent from the timer means 53 and when a completed electrical charging sensor means 48 is not turned ON. Although an electrical charging time of a rechargeable battery cell 46 of the electrical charger 45 is varied in response to an electrical discharging state, a signal output time of the timer means 53 is set to a longer time at a complete electrical discharging of the worst condition as the electrical charging time, for example, 20 hours, it becomes sufficient as the electrical charging judging time. In the case that the charging completion sensing means 48 is not turned ON when the timer means 53 is turned ON, it can be judged that the electrical charger 45 is in its troubled state and the trouble of the electrical charger 45 is advised to a person in charge of transportation with an informing output means 54 and then a troubled insulated box is prevented from being used.

Abstract: PURPOSE:To effectively use the space by significantly reducing the installation space and ensure the quality by maintaining the cold storage bin in a certain temperature range by keeping the coldness during the heat accumulation operation by means of opening and closing the temperature controller unit for the heat accumulation compartment. CONSTITUTION:A compressor 42 is operated to perform a heat accumulation, wherein the heat accumulation compartment 27 is cooled by a cooling unit 29 which has been cooled and the heat storage material 28 is cooled and frozen by the cold air in the heat accumulation compartment 27. When the temperature of the heat accumulation compartment temperature sensing part reaches the set temperature of approximately -20 deg.C past the completion of freezing of the storage material 28, a heat accumulation compartment temperature regulator 32 is started to cause the compressor 42 to repeat the start and stoppage so as to maintain the temperature of the heat accumulation compartment 27 within a certain temperature range. The cold storage bin 41 is cooled by the cold air in the heat accumulation compartment 27 which enters from an opening 35 and a vent 36 as well as through the heat insulating partition 34. As the heat accumulation compartment 27 is controlled in the constant set temperature range, the quantity of heat to cool the cold storage bin 41 becomes constant. Although the cold storage bin 41 releases heat to the atmosphere, it is balanced out to maintain the temperature at about 0 deg.C to 5 deg.C by the cooling effect by the heat accumulation compartment 27 and the atmosphere.

Abstract: PURPOSE:To obtain a highly economical cold accumulation type cold-keeping storeroom without the need for other heating elements by disposing a heat accumulator for accumulating heat radiated from capacitors on the side wall surface of the cold-keeping storeroom accommodating therein a cold accumulating agent and by heating the cold insulating room with heat from the heat accumulator when an external air temperature is low. CONSTITUTION:On the ceiling-plane of a cold-keeping storeroom body 17 is equipped a cooler 21 consisting of a cold accumulating agent 23 and a cooling pipe 24 that cools and freezes this cold accumulating agent 23. On the other hand, a heat accumulator 27 is closely fixed on the side surface part of the cold-keeping storeroom body 17. Heat accumulating capacitors 34 are disposed inside the heat insulating wall correspondingly facing the heat accumulator 27, and only when an external air temperature is low, a flow path is changed over to supply hot gas from main capacitors 36. In this arrangement, heat can be accumulated simultaneously with a cold accumulating operation when an external air temperature is low, and hence an article can be prevented from freezing without using other heating elements such as a heater.

Abstract: PURPOSE: To simultaneously satisfy functions as a cold storage and a refrigerator by bending zigzag a cooling pipe on the same plane and allowing the pipe to stick to a wall surface part facing the inside of a cold storage reservoir by a fixing metal fitting with a heat transfer fin in an upper direction. CONSTITUTION: When a compressor 12 is operated, cooling operation is started, a cold storage agent 16 being filled into a cold storage reservoir 9 starts to be frozen by a cooling pipe 15, and at the same time the inside of the cold storage bath is forcibly cooled via a lower wall 9b. In this case, even if separation is made from a power supply, the cold insulation can be made for a specific amount of time in the reservoir due to the melting latent heat of the cold storage agent 16. Also, when power is turned on, cold insulation goods being stored in the cold storage reservoir can be efficiently and rapidly cooled due to natural convection since a lower wall 9b of the cold storage reservoir 9 where the cooling pipe 15 adheres to is located inside the cold storage bath. Further, the cold storage agent 16 is frozen from the surrounding of the cooling pipe 15 and heat travel becomes insufficient. However, since heat is transferred by a heat transfer fin part 17b being fixed to the cooling pipe 15, the upper cold storage agent 16 can be efficiently and positively frozen to the center of the cold storage reservoir 9, thus extending freezing time.
