Its main function is to achieve the transfer of heat and moisture through the core to achieve energy saving and improve the indoor environmental quality. When the indoor exhaust air and fresh air flow through the heat exchange core alternately, heat and mass transfer occurs due to the temperature difference and steam partial pressure difference of the airflow on both sides of the airflow partition. Specifically, the temperature is transferred from the hotter side to the colder side to achieve heat transfer, and the humidity is transferred from the larger side to the smaller side to achieve mass transfer, and finally heat exchange is achieved.
