Abstract
An air cleaning system can rapidly senses occurrence of local pollution, caused by fine dust, through a remote sensor hub and supplies purified air to a polluted area in a concentrated manner, thereby quickly purifying indoor air.
Claims25
An air cleaning system, comprising:
- an air cleaner configured to discharge purified air;
- and
- one or more sensor hubs configured to be spaced apart from the air cleaner, each of the one or more sensor hubs being configured to measure local dust concentrations of an ambient air and transmit local dust concentration data to the air cleaner, the local dust concentration data indicative of the measured local dust concentrations of the ambient air,
- wherein the air cleaner comprises:
- a main dust sensor configured to measure dust concentrations of unpurified air around the air cleaner and to generate reference dust concentration data,
- a wireless communicator configured to receive the local dust concentration data transmitted from the one or more sensor hubs,
- a circulator configured to change a discharge direction of the purified air, and
- a controller configured to receive the local dust concentration data and the reference dust concentration data respectively from the main dust sensor and the wireless communicator, and to determine whether to change the discharge direction of the circulator based on the received local dust concentration data and reference dust concentration data.
