An air conditioner dehumidifier comprising coil portions cooled by a fluid coolant such as by chilled water or refrigerant. As the required air sensible and latent cooling demands and their ratio varies in the conditioned space, the number of operational coil portions and the velocity of the coolant flow through each is controlled, by valves or other means, increasing coolant velocity while reducing the number of operational coil portions and vice-versa, to provide the coil surface area and the coil surface temperature necessary to cause the required degree of dehumidification and the required degree of sensible cooling in the required ratio to maintain comfortable conditions in the conditioned space with low energy consumption at all cooling demands.

An air conditioner comprising a dehumidifier having a plurality of coil portions, coolant supply means and coolant flow control means controlling coolant flow from the coolant supply means and through the coil portions selectively in one at least of a plurality of coolant circuits which embody said coil portions, so as to establish a plurality of stages of dehumidifier capacity, an air flow fan, means controlling air flow from the fan to be through one at least of the coil portions, at least one control sensor located to sense magnitude of load, and coupling means coupling said sensor to said flow control means in such a way that as load reduces from peak load conditions through part load stages towards minimum load conditions, coolant flow is restricted through one at least of the coil portions but coolant flow rate is increased in another of said coil portions to maintain the required sensible heat cooling capacity, in turn increasing the heat transfer coefficient on the coolant side of a heat exchange interface of said other coil portion thereby reducing the temperature of that interface and in turn increasing the ratio of latent heat cooling to sensible heat cooling of that interface.
