AI Technical Summary

Technical Problem

When the dehumidification equipment does not perform dehumidification operation in the existing air treatment system, the refrigerant will remain in the heat exchanger of the dehumidification equipment, resulting in insufficient refrigerant supplied to other equipment of the air treatment system, thereby affecting the performance of the air treatment system.

Method used

When the indoor mechanism is heated, open the flow regulating valve in the dehumidification module so that the refrigerant does not stay in the heat exchanger in the dehumidification module, thereby ensuring that sufficient refrigerant is supplied to the indoor unit.

Benefits of technology

By avoiding refrigerant retention, the heating performance of the indoor unit is ensured and the user experience is improved.
