Electric Thermostat Switch
There are many types of electronic temperature control switches, also called thermostats, and their principles are as follows:
The temperature controller is an electrical switch device that controls the temperature of an air-conditioned room. The temperature range in the air-conditioned room controlled by the temperature controller is generally between 18°C and 28°C. The temperature controller commonly used in window air conditioners is based on the principle of pressure action to push the contacts on and off. Its structure consists of a bellows, temperature bulb (test tube), eccentric wheel, micro switch, etc. to form a sealed induction system and a signal power transmission system.
There are generally two control methods:
One is to control by the temperature change of the object to be cooled, and the steam pressure type temperature controller is mostly used. The other is controlled by the temperature difference of the object to be cooled, and electronic temperature controllers are mostly used. The thermostat is divided into:
Mechanical type is divided into: steam pressure type thermostat, liquid expansion type thermostat, gas adsorption type thermostat, metal expansion type thermostat.
Among them, the vapor pressure type thermostat is divided into: inflatable type, liquid-gas mixed type and liquid-filled type. The mechanical type of household air conditioner is mainly based on this kind of thermostat.
Electronic type is divided into: resistance type thermostat and thermocouple type thermostat.
The role of the circuit system:
The function of the air conditioner circuit system is to control the normal and multi-function operation of the air conditioner, and to protect the normal operation of the compressor and fan motor. The main components of the circuit system are:
The temperature controller, thermal protector, main control switch, running capacitor, fan motor running capacitor, etc. are fixed in the control box. The picture on the left is the electrical circuit diagram of the single-cooling air conditioner. The function of the temperature controller is only to control the start and stop of the compressor.
