What is the working principle of mechanical thermostat?

With our life getting better and better, people are getting richer and have higher and higher requirements for life. We used to use a traditional thermostat at home. With the continuous development, people invented mechanical thermostats, which made our life more convenient. Speaking of this mechanical thermostat, do you know the working principle of this mechanical thermostat? Let's take a look at Bian Xiao.

Brief introduction of mechanical thermostat;

Mechanical thermostat is suitable for indoor temperature control of industrial, commercial and civil buildings. The mechanical thermostat automatically controls the air conditioning equipment by detecting the indoor temperature and comparing it with the temperature set by the user, so as to achieve the purpose of indoor constant temperature. The main control equipment includes: fan coil unit, heating, three-wire or two-wire electric valve, and building management system.

Working principle of mechanical thermostat;

A bimetallic disk with a fixed temperature is used as a heat-sensitive reaction element. When the temperature rises, the generated heat is transferred to the bimetallic disk, and when it reaches the predetermined temperature value, it moves quickly, and the contact is opened or closed through the action of a mechanism. When the temperature drops to the set value of reset temperature, the bimetallic disk quickly recovers, so that the contacts are closed or disconnected, thus achieving the purpose of connecting or disconnecting the circuit, thereby controlling the circuit.

What are the functional characteristics of mechanical thermostat?

Indoor temperature setting

Cooling/heating mode selection

Beautiful appearance and reliable performance.

On/off control, wind speed adjustment

It can be directly installed on the standard junction box on the wall.

Can control two-wire or three-wire electric (ball) valve.

Through the knob setting, the temperature setting is convenient and intuitive.

The switch adopts toggle type, which has comfortable feel and long service life.

Toggle the switch to manually control the system operation and fan speed.

It can be used to control fan coil unit and electric (ball) valve or air valve.

The bimetallic bellows temperature sensing element can ensure accurate temperature control as required.

Automatic hot-cold conversion can be controlled by pipeline thermostat (referring to some types of thermostats)

Special function: 1. Stop working overtime? 2.？ Security shield? 3.？ Wall-hanging method for special installation requirements

All types of thermostats have thermal sensors, which can further improve the control of hot and cold temperatures.

Of course, you should pay attention to the use or installation of any product. Of course, this thermostat is the same. The height must be one meter and two meters when installing. And it should be installed when the air can no longer be sealed. And when installing, don't follow your own ideas, pay attention to the direction of the wire, and install it along the bending direction, otherwise it will damage the wire. When installing in an unfinished home, pay attention to fixing and packaging with things to avoid dirty things entering during decoration.
