Control Method, Principle and Service Life of Thermostat

Thermostat refers to a series of automatic control elements that undergo physical deformation inside the switch according to the temperature change of the working environment, thereby producing some special effects and generating on or off actions, also called temperature control switches, temperature protectors, Temperature controller, referred to as thermostat. Or the temperature is transmitted to the temperature controller through the temperature protector, and the temperature controller issues a switch command to control the operation of the equipment to achieve the ideal temperature and energy saving effect. Thermostats have a very wide range of applications, and are used in many products such as home appliances, motors, refrigeration or heating according to different types of thermostats.


1. Control method of smart central heating thermostat


Smart WiFi thermostat control methods are generally divided into two types; one is controlled by the temperature change of the object to be cooled, mostly using a steam pressure temperature controller, and the other is controlled by the temperature difference of the cooled object, and electronic temperature controller is mostly used.


2. The working principle of the smart central heating thermostat


The working principle of the intelligent central heating thermostat is to automatically sample and monitor the ambient temperature through the temperature sensor. When the ambient temperature is higher than the control set value, the control circuit starts, and the control hysteresis can be set. If the temperature is still rising, when it rises to the set over-limit alarm temperature point, the over-limit alarm function will be activated. When the controlled temperature cannot be effectively controlled, in order to prevent the equipment from being damaged, the equipment can also be stopped by the function of tripping to continue running. Mainly used in various high and low voltage switch cabinets, dry-type transformers, box-type substations and other related temperature application fields used in the power sector.


3. The service life of the smart central heating thermostat


Thermostats are widely used in various home appliances, such as refrigerators, water dispensers, water heaters, coffee pots, etc. The quality of the thermostat directly affects the safety, performance and life of the whole machine, and is a very critical component. Among the many technical indicators of intelligent central heating thermostats, life is one of the most important technical indicators to measure thermostat products. The home appliance standard stipulates that the life of the thermostat is at least 10,000 times. Some home appliances, such as the thermostat that controls the motor and the compressor in refrigerator products, and some thermostats in the liquid-filled radiator require at least 100,000 times.
