Title:
DEHUMIDIFICATION MODE CONTROL METHOD AND APPARATUS, DEVICE, MEDIUM, AND PROGRAM PRODUCT
Document Type and Number:
WIPO Patent Application WO/2023/070606
Kind Code:
A1
Abstract:
A dehumidification mode control method and apparatus (400), a device (500), a medium, and a program product. The method comprises: when detected that a dehumidification requirement exists in a passenger compartment, obtaining a dehumidification load of a heat pump system and an external environment temperature; then according to the dehumidification load, the external environment temperature and a load threshold, determining whether to enter a first dehumidification mode, the first dehumidification mode being used for: in a dehumidification process, supplementing heat and increasing the temperature of air passing through a first internal heat exchanger by means of an external heat exchanger absorbing the heat of an external environment; if so, then determining a control instruction of the first dehumidification mode according to the air temperature on a plurality of first preset positions in a heat exchange box and a supercooling degree of a heat exchange medium on at least one second preset position in a transmission pipe; and then outputting the control instruction so that a first target temperature and a second target temperature simultaneously meet preset requirements of a dehumidification function. Thus, the technical problem of how to dehumidify a new energy automobile is solved.
