What are the different applications of thermostat?

Views:5     Author:Fisher      Publish Time: 2019-12-06      Origin:Site

The working principle of the thermostat, according to the temperature change of the working environment, physical deformation occurs inside the switch, thereby generating some special effects, generating a series of automatic control components for conduction or disconnection, also called temperature control switch, temperature protector , temperature controller, referred to as temperature controller.

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 device to achieve the desired temperature and energy saving effect. The application range is very wide, and the application is based on different types of thermostats in the home appliance, Among many products such as motors, refrigeration or heating.

The control method is generally divided into two types; one is controlled by the temperature change of the object to be cooled, and the vapor pressure type temperature controller is often used, and the other is controlled by the temperature difference of the object to be cooled, and the electronic temperature is often used. Controller.

The types of thermostats are: liquid-up thermostat, pressure thermostat, electronic thermostat, digital thermostat.

It is now used in household heating equipment controlled by intelligent thermostats.

1. Convenience: Automatically adjust the wall-hung boiler in advance or delay after switching, eliminating manual operation, which is most necessary for office workers;

2, comfort: every day, morning, evening, night, room temperature, automatic height adjustment, avoiding the morning waking up and going home after work, waiting for the room to heat up and freezing;

3, gas: change the water temperature control behind the extensive control of advanced and accurate room temperature control, plus the time zone to set the room temperature on demand, no need to open the day and night to burn gas;

4, rest assured: when the room temperature is too low, forced to start the wall-hung boiler, only need very little gas, you can safely carry out room frost protection.

 

Mechanical and electronic: Mechanically, two layers of different thermal expansion coefficients are pressed together. When the temperature changes, his curvature changes. When it is bent to a certain degree, it is turned on (or disconnected). The circuit makes the cooling (or heating) equipment work. The electronic type converts the temperature signal into an electric signal through a temperature sensing device such as a thermocouple or a platinum resistor, and controls the relay through a circuit such as a single chip microcomputer or a PLC to operate (or stop) the heating (or cooling) device. There is also a mercury thermometer type, when the temperature is reached, there will be contacts and mercury connected.
