VENTILATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/112470
Kind Code:
A1
Abstract:
This ventilation system 1 comprises a refrigerant circuit 60, an air supply fan 22 that takes in outdoor air to indoors through a first heat exchanger 12 of the refrigerant circuit 60, an exhaust fan 42 that exhausts indoor air to outdoors through a second heat exchanger 32 of the refrigerant circuit 60, a temperature sensor 24 for sensing the blowout temperature TS of the air supply fan 22, a monitoring sensor 80 for sensing state information CT pertaining to the indoors, and a control unit CU that adjusts the indoor ventilation volume. A first mode and a second mode that are described below are included as classifications of control modes in which the control unit CU operates. First mode: a control mode in which a higher weighting is applied to the state information CT, among the state information CT and the blowout temperature TS that can be used in adjustment of the indoor ventilation volume. Second mode: a control mode in which a higher weighting is applied to the blowout temperature TS, among the state information CT and the blowout temperature TS that can be used in adjustment of the indoor ventilation volume.
