Working principle of thermostat

The thermostatic automatic sampler is equipped with a cooling/heating module, which uses effective cooling air from Peltier elements. When on, set the front of the heating/cooling Peltier element according to the temperature. The fan draws air from the sample tray area and passes it through the channels of the heating/cooling module. Fan speed is determined by ambient conditions (e.g. ambient humidity, temperature). In the heating/cooling module, the air reaches the temperature of the Peltier element, and then these thermostats are blown to the special sample disk, where they are evenly distributed and flow back to the sample disk area. From there the air enters the thermostat. This circulation mode ensures efficient cooling/heating of the sample bottle.

In the cooling mode, the other side of the Peltier element will become very hot. In order to maintain the farsighted performance, it must be cooled, which is achieved through the large heat exchanger on the back of the thermostat. The four fans blow air together from left to right to exhaust the heated air. The fan speed determines the temperature control of the Peltier element.

During cooling, condensation occurs in the heating/cooling module. Condensate will be everywhere in the thermostat.
