Title:
AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2019/087632
Kind Code:
A1
Abstract:
This air conditioner comprises: an indoor heat exchanger; an indoor fan; an indoor discharge port; an up/down air direction plate; an indoor heat exchanger temperature sensor; and a control device. The control device has an air volume control unit for restricting the air volume of the indoor fan at the start of a heating operation, and an air direction control unit for controlling the up/down air direction of the up/down air direction plate. The air volume control unit controls the air volume of the indoor fan at the start of the heating operation so that the air volume increases as the temperature of the indoor heat exchanger increases. The air direction control unit restricts the position of the up/down air direction plate at the start of the heating operation so that the up/down air volume plate is oriented toward at least an upward direction within a discharge direction adjustment range.
