Abstract:
A heating, ventilation and air conditioning (HVAC) unit for a conditioned space comprising:a cooling coil divided into a first cooling coil circuit and a second cooling coil circuit each in fluid communication with coolant from a coolant supply, each of the first and second cooling coil circuits having a leading and trailing surface, the leading surfaces being defined by first and second perpendicular axes with the coil being divided along the first axis into the first and second circuits;an outside air intake introducing air from outside to inside the conditioned space, the outside air intake being positioned to distribute outside air to substantially the center of the leading surface of the first cooling coil circuit along the second axis;a return air intake for introducing return air from inside the conditioned space to the leading surface of the second circuit of the coil;a first valve in fluid communication with the coolant supply and the first cooling coil circuit, the first valve having an open setting permitting and a closed setting preventing the circulation of coolant through the first cooling coil circuit;humidity control means coupled to the first valve for actuating the first valve between the open and closed settings as a function of a need to decrease the humidity of the outside air introduced into the conditioned space; andan exhaust introducing dehumidified outside and return air to the conditioned space.
