Abstract: PROBLEM TO BE SOLVED: To provide a vehicle-mounted refrigerator in which a battery can be prevented from dying even if the load current is varied by detecting overdischarge at a correct battery voltage even if the length of wiring is different among different types of vehicle. SOLUTION: A control means for preventing overdischarge 13 controls the temperature in the compartment by varying the voltage of a cooling means 8 comprising a thermoelectric element 5 depending on the temperature in the compartment and detects overdischarge of a battery 15 by detecting the input voltage through an input voltage detecting circuit 14. Since the input voltage is compensated by a voltage corresponding to the load current, overdischarge can be detected constantly with a correct battery voltage and the battery is protected against dying.

Abstract: PROBLEM TO BE SOLVED: To restrict temperature rise when a damper is closed and permit the improvement of quality of preservation of foods by a method wherein cold storage agent is provided in a cooling duct which conducts cold air directly from a damper device provided on the ceiling surface of a low temperature chamber. SOLUTION: Cold storage agent 22 is provided in a ceiling surface discharging duct. Cold air, cooled by a cooler 8, is ventilated forcibly by a fan 9 to cool foods to a predetermined temperature by sending the cold air into a refrigerating chamber 5 through a damper device 11. The opening and closing of the damper of the damper device 11 is controlled by a temperature detected by a temperature detector 13 for a low temperature chamber 6 to store cold heat in the cold heat storage agent 22 when the damper device 11 is opened to send cold air thereinto and release the heat of the cold air, stored in the cold heat storage agent 22, in a low-temperature chamber vessel 17 when the damper device 11 is closed whereby the variety of temperatures in the upper and lower parts of the low temperature chamber is minimized. According to this method, cold air is showered from the upper part of the low temperature chamber even when the damper device is closed and the variety of temperature in the low temperature chamber can be minimized.

Abstract: PURPOSE: To prevent a liquid refrigerant from stagnating in a condensation-proof pipe to produce a poorly cooled state by being introduced into a condensation proof pipe, and keep a thermal effect to the inside of a refrigerator to a minimum, and at the same time, prevent a condensation on the refrigerator from happening by providing a dryer and capillary tube respectively in the condensation-proof pipe and bypass pipe. CONSTITUTION: A refrigerant is split by a switching valve 4 into a condensation proof pipe 5 on which a dryer 7 and capillary tube 8 are arranged, and bypass pipe 6 on which a second dryer 10 and second capillary tube 11 are arranged. The temperature of a freezer chamber is detected by a temperature sensor, and a dew-point temperature is deduced by an outside air temperature sensor on the external surface of the refrigerator, and the switching valve 4 splits the refrigerant into the condensation-proof pipe 5 and bypass pipe 6 so that the temperature of the temperature sensor may become the dew-point temperature or higher. By this method, the liquid refrigerant does not stagnate in the condensation-proof pipe, and also, the condensation-proof pipe is prevented from becoming warm to the dew-point temperature or higher, and the thermal effect to the inside of the refrigerator can be kept to a minimum.
