Abstract
An air conditioner includes: a heat-medium air heat exchanger that exchanges sensible heat between a heat medium having a temperature adjusted by the heat-medium temperature adjuster and ventilation air blowing to a space to be air-conditioned; a heat transfer portion having a flow path through which the heat medium circulates to transfer heat with the heat medium having the temperature adjusted by the heat-medium temperature adjuster; a large-inner-diameter pipe that forms a heat-medium flow path between the heat-medium temperature adjuster and the heat transfer portion; and a small-inner-diameter pipe that forms a heat-medium flow path between the heat-medium temperature adjuster and the heat-medium air heat exchanger. The small-inner-diameter pipe has small inner diameters ϕH and ϕC, compared to the large-inner-diameter pipe.
