Fresh air conditioning system

A fresh air conditioning system, comprising

• a first cooling device, including a first cooling end and a first heating end;
• a dehumidifying rotary defining a first section and a second section, wherein when the first section works as a processing zone, then the second section works as a regenerating zone, wherein when the first section works as the regenerating zone, then the second section works as the processing zone;
• an airflow switching device connected to the first cooling device and configured to selectively direct a fresh airflow from a first space to the first cooling end or the first heating end of the first cooling device;
• a first heat exchanger connected to the second section of the dehumidifying rotary and configured to conduct a heat exchange with a return airflow from a second space;
• a first energy switching device connected to the first cooling device and the first heat exchanger and configured to selectively transfer energy from the first cooling end or the first heating end to the first heat exchanger;
• a second cooling device including a second cooling end and a second heating end, wherein the second cooling end is connected to the first section of the dehumidifying rotary, and after flowing through the first section of the dehumidifying rotary, the fresh airflow from the first space conducts heat exchange with the second cooling end of the second cooling device, and then flows to the second space;
• a second heat exchanger connected to the first heating end of the first cooling device and the second heating end of the second cooling device and the first section of the dehumidifying rotary, wherein the fresh airflow from the first space flows to the first section of the dehumidifying rotary after the fresh airflow completes heat exchange with the first heating end of the first cooling device and then with the second heat exchanger;
• and
• a second energy switching device connected to the second heating end of the second cooling device, the first heat exchanger and the second heat exchanger to selectively transfer energy from the second heating end of the second cooling device to the first heat exchanger or the second heat exchanger;
• wherein the fresh airflow from the first space conducts heat exchange with the first cooling end or the first heating end of the first cooling device and then flows through the first section of the dehumidifying rotary to the second space, and the return airflow from the second space conducts a heat exchange with the first heat exchanger and then flows out through the second section of the dehumidifying rotary.
