Refrigerator is one of the essential electrical appliances in modern homes, it can keep food and beverages cold and prolong their preservation time. The ability of refrigerators to cool is related to the electronic components that control the temperature.
The thermistor is a special resistance device. Although the thermistor is small in size, it plays an important role in many fields. The resistance value of the thermistor will change with the temperature.
In the constant temperature equipment of the refrigerator, the thermistor plays an important role. It is installed inside the refrigerator to monitor and control the temperature inside the refrigerator.
The thermistor can send a corresponding signal to the refrigerator control system by measuring the temperature of the surrounding environment. When the temperature rises, the resistance value of the thermistor will decrease, and the system will adjust the refrigerant flow and cooling power inside the refrigerator according to this signal to maintain a constant low temperature state.
In addition to the application in constant temperature equipment, thermistors in refrigerators can also be used for fault alarm functions. If the refrigerator is overheated or has other abnormal conditions, the thermistor will sense it immediately and send an alarm signal to the refrigerator control system to prompt the user to deal with it in time.
Despite their small size, thermistors play an important role in refrigerators. It helps the refrigerator to maintain a constant low temperature by measuring the ambient temperature, and it will give an alarm in time when there is a failure, so as to ensure the user's personal health and the freshness of food. In addition, it also plays an important role in temperature measurement, fire alarm and medical equipment.
