Document Type and Number:
Japanese Patent JP2021008977
Kind Code:
A
Abstract:
To eliminate a possibility that a gas sensor measures a concentration of introduced outside air to unintentionally hinder air supply control from being conducted even if a gas concentration in an indoor space is high with regard to an air conditioner which measures the concentration of the predetermined gas in an indoor space to ventilate the indoor space properly.SOLUTION: An indoor unit (10) of an air conditioner (1) includes: a casing (11); an indoor fan (12); an air supply passage (P1) which introduces outside air into an indoor space; a gas sensor (15) which measures a concentration of a predetermined gas in the indoor space; and a control unit (16). The control unit (16) stops introduction of outside air when the concentration of the predetermined gas becomes a predetermined value or lower in a case that the indoor fan is driven when outside air is introduced into the indoor space through the air supply passage. The control unit (16) continues the introduction of outside air even if the concentration of the predetermined gas becomes the predetermined value or lower in a case that driving of the indoor fan (12) is stopped when outside air is introduced into the indoor space through the air supply passage (P1).SELECTED DRAWING: Figure 5
