Heating is heating an object with a heat source.

The purpose of heating is to raise the temperature of liquid, solid or gas. The constant temperature heating is to keep the temperature of liquid, solid or gas stable at a certain temperature scale or temperature value. The heat supplied is basically equal to the heat cut in the process of its own heat dissipation.

Principle of thermostat

The measuring end of the temperature probe extends in the air inside the thermostat, and can not avoid touching with objects or boxes. Real-time monitoring of the temperature in the box can set the constant temperature scale of the thermostat on the control panel, i.e. setting the allowable upper and lower temperature limits. When the probe detects that the temperature is lower than the lower limit, the hot air fan is opened to heat and the temperature starts to rise again. When the probe detects that the temperature is higher than the upper limit, the temperature of the thermostat can be set. Time limit, open refrigeration compressor refrigeration, temperature drop, so back and forth control.

Some constant temperature is relatively advanced, can set deviation, for example, under normal circumstances, the temperature should reach the lower limit when the beginning of heating, heating at this moment later, because after the beginning of heating, the temperature may fall for a period of time, at this time can set deviation, so that it can be heated or refrigerated in advance.
