Abstract

A heat transfer system first includes an air conditioner which includes an evaporator. The system further includes a chamber having an air duct including an input end for receiving fresh ambient make up air and for also receiving recycled air. The air duct also includes an output end to move conditioned air passed the evaporator and into the chamber, with intermediate zones between the input end and the output end. The intermediate zones include a return air zone, a make up air zone, an air handler zone, and an air supply zone. The system also includes a distiller with an input end to receive water from a feed water source, an outputs, an exhaust chimney to direct the flow of excess heat and recycled air to atmosphere or for recirculation, and a heater element. Furthermore, the system includes a passive transfer assembly having a pair of ends with a coil at each end thereof and a pair of lines connecting the coils there between forming a closed loop for a second working fluid to pass. The first heated end is located in operative association with the exhaust chimney of the distiller and the second chilled end located in operative association with the second output end of the air duc…
