Abstract
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.
