PCT No. PCT/AU92/00235 Sec. 371 Date Jan. 24, 1994 Sec. 102(e) Date Jan. 24, 1994 PCT Filed May 25, 1992 PCT Pub. No. WO92/20973 PCT Pub. Date Nov. 26, 1992.An air conditioner with coolant pumped from a chiller first through a heat exchange conduit of an outside air heat exchanger to provide a minimum wetted surface temperature when treating undiluted outside air at its current temperature and humidity as it passes through this heat exchanger so to make maximum use of the available potential difference between the outside air and the coolant and therefore to cause maximum dehumidification. The leaving coolant from the outside air heat exchanger is the source of the coolant which then passes to the return air heat exchanger which cools and dehumidifies the return air. The leaving air streams from the return and outside air heat exchangers are mixed to become the supply air for a conditioned room which is economically dehumidified without need to overcool and reheat, nor to curtail the design flow rate of ventilation air and hence without contributing to conditions which are associated with the "sick building syndrome." As a consequence there results a design which performs to standards over its full range of operation with low noise and low operating costs.
