Abstract: A primary air flow path has a pre-cooler and an evaporator. A secondary air flow path includes portions of an air conditioner assembly including a compressor and an condenser. The air conditioner assembly also has lines connecting the compressor and the condenser the evaporator. A cooling tower has a coolant fluid input and output with a heat exchanger section. The heat exchanger section conveys coolant fluid. A pump causes cooling flow of water over the section. The coolant fluid output is adapted to feed a coolant fluid in two coolant fluid paths. The first fluid path is in heat exchanging relationship with the air conditioner assembly. The second fluid pat is coupled to the pre-cooler.

Abstract: An evaporative condenser system has an air handler with an input end and an output end with a fan to facilitate the movement of the air. An air cooler has at least one conical spiral coil having a top end and a bottom end, each with linear extents in the output ends and the input ends of the air handler. A pump moves a working fluid through the coil. A cooling water pathway has a water recycle input and a reservoir for the cooling water adjacent to the bottom end of the air cooler coils. The reservoir has a submersible sump pump for moving the cooling water to an elevated location with a sprayer.

Abstract: Conduits or chambers for use in directing and conditioning the flows of air or fluids using a wide variety of heat generation, cooling, variation of pressure or vacuum and the effect of this on a member that is moved or rotated from one chamber to other chambers to effect the removal of moisture, particles and some gasses from an air or fluid stream that is conditioned for a specified use; generally, but not limited to a living or storage environment.

Abstract: An air conditioning system is provided which utilizes both exhaust and outside air energy to regenerate the latent and sensible heat removal operations while not detrimentally increasing the bacterial contamination risks associated with exhaust air energy recoupment. The air conditioning system includes a supply air passageway through which supply air flows during conditioning thereof and a desiccant wheel for reducing the humidity of supply air in the supply air passageway. The system also includes separate exhaust air and outside air passageways. A first circulation assembly is provided for circulating a heat transfer medium between a refrigerant-type cooling assembly and a first transfer zone disposed in the exhaust air passageway and a second circulation assembly is provided for circulating a heat transfer medium between the cooling assembly and a second transfer zone disposed in the outside air passageway.

Abstract: A curb for a roof air conditioning package is enclosed on all sides and the bottom to form a plenum. The air conduits from and to the building are connected to the plenum rather than the unit. The plenum is reinforced by a wood collar around the top, which then serves as a second function of a roofing nailer strip. The curb is leveled by wedge supports.
