Temperature sensor in the development of the smart refrigerator

Original Six door refrigerator received attention, which is equipped with a new generation of vacuum chamber refrigerator , while the new intelligent vacuum ice greenhouse according to different vegetables, fish and other food ingredients , automatic switching optimal preservation temperature 1 ℃ / -1 ℃ , the eliminating the need for manual adjustment of trouble, easy to enjoy healthy and delicious .Especially in terms of energy saving , a refrigerator dedicated power saving procedure in the case of food preservation does not affect the cooling intensity is slightly weak tone , while the control speed of the compressor . Open the refrigerator door is usually the voice prompts after 1 minute will be shortened to 30 seconds after the prompt , and the LED lights inside the refrigerator will be prompted by the lights dimmed refrigerator door closed as soon as possible . Intelligent memory analysis , and by Camshaft Position Sensor of the refrigerator door opening and closing frequency analysis using household usage, no other family members at night or infrequently used defrost heater operation period , in the period of high frequency , inhibiting due to temperature rise caused by the defrost heater .It is reported that the temperature sensor in the refrigerator works is this : decide whether to open the compressor according to the temperature of the refrigerator and freezer cases , if the freezer temperature is too high , then open the electromagnetic popular V1, close the valve V2, V3, open at the compressor , high temperature high pressure superheated condensed through the condenser , dry filter and dried down the capillary orifice tube , refrigerant vaporized in an evaporator to produce low-pressure low-temperature drying gas . Flows into the refrigerator compartment through the solenoid valves V1 , so rapidly reducing the temperature of the refrigerator , when the compressor temperature reaches the required closed while closing the electromagnetic valve V1. If the freezer temperature is too high , you should open the V2 closed V1, V3. Solenoid valve V3 is mainly used for defrosting the freezer . V3 of the need to open the box , passing through the freezing chamber can be uniform vaporization frost freezer compartment temperature from the compressor outflow pressure gas . To achieve the effect of frost . Generalized frost shorter time , otherwise it will hurt the stored food .Essential quality refrigerator Auto Temperature Sensor performance , and its identification as follows: Since the refrigerator temperature sensor series negative temperature coefficient thermistor , so we can measure the resistance change using the " hand method ." When the hand grip temperature sensor , its resistance varies with temperature , normal to tens of thousands of European Euro . After the hand release , its resistance and recovery. If the holding temperature sensor , the resistance change, or a small range of variation , the temperature sensor is defective and should be replaced.
