As a air -conditioning equipment that provides fresh air, according to the requirements of the use environment, the function can meet the constant temperature and humidity or simply provide fresh air, dust removal, dehumidification (or humidification), cooling and other functions.To determine, summarize in a sentence, the more complete the function of the fresh air -changing machine, the higher the cost will be corresponding.In terms of the application principle of the new group, Xiaobian will introduce you in detail:
The temperature control system of the fresh air unit consists of the temperature sensor and the electric regulating valve installed in the air supply pipe.The role of the controller is to pass the air supply temperature detected by the temperature sensor placed in the air supply pipeline to the temperature controller and compare it with the temperature set by the controller.According to the PI operation results, the temperature controller sends an open/off -turn valve signal to the electric regulating valve to keep the air supply temperature within the required range.
Electric regulating valve and fan chain to ensure that the wind valve is closed at the same time when cutting off the fan power supply.When the fan is cut off, the electric regulating valve can also be linked to the fan to turn off the electric regulating valve.Users can choose two chain line connection methods: power -off resetting equipment and power control equipment according to the specific situation.
When cooling, the temperature controller is placed in the refrigeration mode.When the temperature measured by the sensor is reached or lower than the set temperature, the temperature controller closes the valve signal to the electric valve to the electric valve.If the measuring temperature does not reach the set temperature, the temperature controller gives an electric valve a valve signal to the electric valve, and the electric valve open valve connection to open the valve.When heating, the temperature controller is placed in the heating mode.
When the temperature measured by the sensor is reached or higher than the set temperature, the temperature controller offses a valve signal to the electric valve, and the turnover valve joint connection connecting valve is closed.If the measuring temperature does not reach the set temperature, the temperature controller gives an electric valve a valve signal to the electric valve, and the electric valve open valve connection to open the valve.
The above is the introduction of the relevant application principle information about the fresh air gas exchange machine. I hope that the above content will help you.
