Compared with the central air conditioner, the principle of the fresh air gas exchange machine is not complicated. The fresh air gas exchange machine is divided into one -way flow, two -way flowing new and full heat exchange.The new energy -saving temperature control system is exchanged. The working principle is more complicated and the use effect is also good.
Electric regulating valve and fan chain to ensure that the wind valve is also turned off at the same time when the power supply is cut off. The electric regulating valve can also be connected with the fan. When the fan is cut off, the electric regulating valve is turned off.Temperature controllers, temperature sensors and electric regulatory valves installed in the air supply pipe.
The role of the controller is to compare the air supply temperature detected by the temperature sensor placed in the wind channel to the temperature controller and the temperature setting of the controller. According to the result of the PI operation, the temperature controller is adjusted by the electric controller to the electric adjustment.A signal of a valve on/off the valve, so that the air delivery temperature is maintained in the required range.
When the filter is blocked or when it exceeds the prescribed value, the voltage switch gives a switch signal.When the cooling is needed, 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 gives the electric valve to a valve signal, and the control valve contact of the electric valve is turned on to close the valve.If the measurement temperature does not reach the set temperature, the temperature controller gives an electric valve to open a valve signal, and the electric valve open valve connection connecting the valve to open it.
When the heating is needed, the temperature controller is placed in the heating mode. When the temperature measured by the sensor reaches or higher than the set temperature, the temperature controller gives the electric valve to a valve signal.Essence
It is recommended that you install the fresh air unit, and then install the fan ducts separately in each room, so that you can make long and short, and at the same time, you can also achieve a more energy -saving and comfortable purpose.If the measurement temperature does not reach the set temperature, the temperature controller gives an electric valve to open a valve signal, and the electric valve open valve connection connecting the valve to open it.
