The present development is a building air cooling system using cool ground water, e.g. well water. Building air is cooled by coming into direct contact with cool ground water in a compact chamber using PVC packing for maximizing heat transfer efficiency, conserving space and reducing the required ground water pumping power consumption without requiring expensive compression and expansion cycles of the traditional air conditioning systems. If additional cooling is desirable, a second stage traditional air conditioning or heat pump system may also be used.

1. A building air cooling system comprising: a) a pump;b) a fresh water pipe for drawing water from a deep well ground water source; and,c) an air temperature modification unit contained within a housing, wherein the pump is in communication with the fresh water pipe and is configured to deliver water from a deep well ground water source through the fresh water pipe and into the air temperature modification unit, and wherein the air temperature modification unit consists of: 1) an air mixing section comprising a building air intake to allow air from a building to enter into the air mixing section and a fresh air intake to allow air from the exterior environment of the building to enter into the air mixing section;2) a bed of polyvinylchloride (PVC) packing positioned above the air mixing section such that the air from the air mixing section must pass through the PVC packing as the air rises within the air temperature modification unit;3) a ground water discharge pipe mounted above the bed of PVC packing and connected to the fresh water pipe, wherein the ground water discharge pipe is oriented to feed ground water to the bed of PVC packing with the water counter-flowing relative to the air from the air mixing section;4) a water discharge positioned below the air mixing section which allows water that has been feed through the PVC packing to exit from the air temperature modification unit;5) a plurality of heat pump coils positioned above the ground water discharge pipe such that the air from the PVC packing section must pass over the heat pump coils as the air rises within the air temperature modification unit;6) a demister positioned above the heat pump coils such that the air from the heat pump coils must pass through the demister as the air rises within the air temperature modification unit; and,7) a vent to feed the treated air back into the building. 2. The building air cooling system of claim 1 further comprising a circulating fan to force air from the demister into a building. 3. The building air cooling system of claim 1 further comprising a second stage compression and expansion system. 4. A method of cooling and conditioning building air comprising: a) providing the building air cooling system of claim 1;b) allowing air from the building to enter into the air temperature modification unit air mixing section through the building air intake and allowing air from the exterior environment of the building to enter into the air mixing section through the fresh air intake;b) allowing air from the air mixing section to rise within the air temperature modification unit and to pass through the bed of polyvinylchloride (PVC) packing material;c) delivering water from a deep well ground source into the air temperature modification unit through the ground water discharge pipe and discharging the water into the PVC packing material such that the water contacts the air and is counter-flowing relative to the air from the air mixing section;d) allowing the water remain in contact with the air to thermally equilibrate the air and the water;e) allowing the thermally-equilibrated water to drain through the water discharge;f) allowing the thermally-equilibrated air to pass over the heat pump coils and allowing the air to be temperature modified by the heat pump coils;g) allowing the temperature-modified air to flow through the demister;h) forcing the temperature-modified air through the vent and into the building.
