A temperature and humidity control system for natatoriums. The system provides a constant volume of air circulation which is used to control temperature and humidity in the natatorium while inhibiting the accumulation of moisture on the surfaces defining the natatorium. Usually, ambient air is introduced into the system and moisture latent air discharged from the system under controlled conditions. When the humidity of the ambient air is too great the system operates in a self-contained cycle. Return air from the natatorium flowing through the system is treated to maximize its relative humidity. Subsequently, it flows across a cooling coil. This cooled air flows through a heat exchange module where it is placed in exchange relationship with the air being drawn from the natatorium. It cools the air drawn from the natatorium to maximize its relative humidity and this air in turn flows across the refrigeration coil removing substantial quantities of moisture. Combining the refrigeration coil with the heat transfer module and the other components in the system, the sensible/latent heat split is shifted towards higher latent output increasing the overall efficiency of the system as a dehumidification device.

A system for providing a continuous flow of air to control surface condensation, humidity and temperture in a defined environment which comprises: means to introduce return air into the system from the defined environment at a first humidity and first temperature; means to measure the humidity of said return air; means disposed within the system to exhaust one portion of said return air to ambient; means to recycle another portion of said return air; means to flow through the system intake air, said intake air at a second humidity and a second temperature; means to discharge continuously into the defined environment supply air at a third humidity and a third temprature; a heat recovery module having an exhaust side through which the return air flows and an inlet side through which the intake air flows; a refrigeration module having first and second zones, the first zone downstream of and in communication with the exhaust side of the heat recovery module, the second zone upstream of and in communication with the intake side of the heat recovery module, the second zone including means to cool the return air flowing therethrough; means to control the flow of the return air from the first zone to the second zone to cool said return air; means to flow said cooled recycled return air as intake air from the second zone through the intake side of the heat recovery module, said intake air in heat exchange relationship with the return air flowing through the exhaust side of the heat recovery module, to thereby cool the return air flowing through the exhaust side of the heat recovery module and to increase the relative humidity of said return air, which return air then flows through the second zone and means to control the flow rates of the return air and the intake air to discharge the supply air.
