Title:
AIR-CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/261322
Kind Code:
A1
Abstract:
This air-conditioning device which performs air-conditioning operation for a space to be air-conditioned comprises a heat exchanger, a blower, a filter, and a control unit. The heat exchanger circulates a refrigerant therein and provides heat exchange between the refrigerant and the air in the space to be air-conditioned. The filter allows the air in the space to be air-conditioned to flow into the heat exchanger. The filter filters the air flowing from the space to be air-conditioned to the heat exchanger. The control unit detects the state of the blower and the state of the heat exchanger and/or the filter, and determines whether or not the air-conditioning device needs to be cleaned on the basis of the state of the blower and the state of the heat exchanger and/or the filter. Upon determining that the air-conditioning device needs to be cleaned, the control unit provides notification prompting to clean the air-conditioning device.
