Humidity control apparatus and air-conditioning system

摘要

A humidity control apparatus and an air-conditioning system are capable of controlling the latent heat processing amount and the sensible heat processing amount in accordance with an indoor heat load without decreasing the operation efficiency. Every time an air route is switched to an air route A or an air route B, the route maintenance time for the switched air route is set on the basis of the heat load within a dehumidification target space, and switching of switching devices is controlled such that the set route maintenance time is ensured.

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
on the basis of the heat load within the dehumidification target space, a preset default time as the route maintenance time in a case where an amount of a processing for the latent heat load increases, andon the basis of the heat load within the dehumidification target space, a time extended from the default time as the route maintenance time in a case where an amount of a processing for the sensible heat load increases.
