Claim Text:
1. A humidity control apparatus comprising: a main body including an air inlet into which air from a dehumidification target space is taken and an air outlet through which air is supplied to the dehumidification target space; an air path arranged within the main body and configured to connect the air inlet and the air outlet; a first moisture adsorption/desorption device arranged within the air path and configured to transfer moisture to air having a relatively low humidity and receive moisture from air having a relatively high humidity; a second moisture adsorption/desorption device arranged within the air path so as to be separated from the first moisture adsorption/desorption device and configured to transfer moisture to air having the relatively low humidity; a cooling device arranged between the first moisture adsorption/desorption device and the second moisture adsorption/desorption device and configured to cool air that has been humidified by moisture transfer by the first moisture adsorption/desorption device or the second moisture adsorption/desorption device; switching devices arranged within the air path and configured to alternately switch between a first air route and a second air route, the first air route being a route through which the air taken through the air inlet passes in order of the first moisture adsorption/desorption device, the cooling device, and the second moisture adsorption/desorption device, the second air route being a route through which the air taken through the air inlet passes in order of the second moisture adsorption/desorption device, the cooling device, and the first moisture adsorption/desorption device in that order; and a controller configured to set, every time the air routes are switched to the first air route or the second air route, a route maintenance time for the switched air route on the basis of a heat load within the dehumidification target space, and control switching of the switching devices such that the set route maintenance time is ensured, wherein the controller sets
