Document Type and Number:
WIPO Patent Application WO/2024/034328
Kind Code:
A1
Abstract:
Provided is an air conditioner that is capable of detecting an indoor temperature without operating a fan during thermostat OFF of a heating operation. This air conditioner includes: an indoor unit that includes a fan, an indoor heat exchanger, a first opening that takes in air, a second opening that discharges air, and a temperature sensor; and an outdoor unit. The first opening is provided downward from the center in the height direction of the indoor heat exchanger. The second opening is provided upward from the indoor heat exchanger. In order to satisfy a conditional expression including the various parameters of an air temperature of the first opening during heating operation, an air temperature of the second opening, a height difference between the center in the height direction of the indoor heat exchanger and the height direction of the second opening, and an area of the second opening, the aforementioned parameters are set so that a flow of air being taken in through the first opening and discharged from the second opening is generated even if the fan is stopped when the heating operation enters a thermostat OFF state in which the heat exchange by the indoor heat exchanger is unnecessary.
