DUCT-TYPE AIR CONDITIONING SYSTEM, AND CONTROL METHOD AND DEVICE FOR INDOOR VENTILATOR THEREOF

WIPO Patent Application WO/2018/126581

A1

A duct-type air conditioning system (1000), a control method and a device for an indoor ventilator thereof. The control method comprises the following steps: upon turning on the duct-type air conditioning system (1000), acquiring an indoor ambient temperature and a set temperature recorded the last time the duct-type air conditioning system (1000) was turned off, and acquiring a current set temperature (S1) according to the indoor ambient temperature and the set temperature recorded the last time the system was turned off; detecting a real-time indoor ambient temperature (S2); according to the current indoor ambient temperature and the current set temperature, calculating a temperature difference between the current indoor ambient temperature and the set temperature, and generating an air velocity adjustment instruction according to the temperature difference (S3); controlling, according to the air velocity adjustment instruction, the indoor ventilator to adjust the air supply velocity (S4) of an indoor unit (200). Thus, the invention acquires a set temperature by means of certain operating rules to achieve automatic control of air supply velocity when the indoor unit (200) cannot receive the parameters of a set temperature and an ambient temperature.
