The present disclosure provides a ventilation and air conditioning system. The ventilation and air conditioning system can include a ventilation and air conditioning body including a ventilation component and an automatic air-output device arranged at a ventilation outlet of the ventilation and air conditioning body and configured to open or close the ventilation outlet according to an operating state of the ventilation component. The automatic air-output device is coupled to a power switch of the ventilation component. When the ventilation component is powered on, the automatic air-output device opens the ventilation outlet of the ventilation component to allow fresh air of the ventilation component to flow indoors. When the ventilation component is powered off, the automatic air-output device closes the ventilation outlet.

The present disclosure relates to an air duct device and an air handling apparatus. The air duct device can include a first air duct and a second air duct. The first air duct has an air inlet and an air outlet. The second air duct has an air input channel passing by the air outlet of the first air duct, and an air outlet that is in communication with the first air duct.

An air conditioning unit (2) comprises a main body (3) including an air inlet (24) and an air outlet (22), the main body (3) defining an airflow passage between the air inlet (24) and the air outlet (22). A fan (28) is disposed within the airflow passage and a thermal element (26) is disposed within the airflow passage upstream of the fan (28). The main body (3) has a front face exposed to a temperature controlled space (8), on which the air outlet is disposed, and the air inlet and thermal element are disposed around the periphery of the front face.
