Title:
AIR CONDITIONER INDOOR UNIT
Document Type and Number:
WIPO Patent Application WO/2018/198400
Kind Code:
A1
Abstract:
The primary purpose of the present invention is to provide an air conditioner indoor unit that does not leak water to the exterior during freeze cleaning. An air conditioner indoor unit (2) has a heat exchanger (16) to perform heat exchange between air and a refrigerant, a drain pan (17) to receive drain water dripping from the heat exchanger (16), and a control unit to control a freezing operation that causes frost or ice to adhere to the surface of the heat exchanger. The volume of the drain pan (17) is greater than or equal to the total volume of frost or ice that adheres to the heat exchanger (16) during the freezing operation. Giving consideration that the drain water is discharged to the exterior of the indoor unit (2) through a discharge pipe, preferably this indoor unit (2) can have a configuration such that the volume of the drain pan (17) is greater than or equal to [total volume of frost or ice adhering - discharge volume of discharge pipe per unit time ∙ the lesser of the time required to melt all frost or ice or the time required for all the frost or ice to drip into the drain pan].
