Abstract:
An assembly for cooling air in a mine environment comprising: a water supply, a source of compressed air, a chiller unit having at least one inlet and an outlet. The chiller unit receives water from the water supp!y and compressed air from the source of compressed air. A venturi receives chilled water from the chiller unit and compressed air from the source of compressed air. The venturi delivers cooled air via a mist nozzle associated with the venturi into the environment requiring air cooling.
Abstract:
A process and the required apparatus for air conditioning the interior of a structure located within a harsh desert like exterior environment. A tube and shell heat exchanger wherein the shell side is wet and the tube side is dry is employed to air condition the interior of the structure. In the operation of the air conditioner, a mass of distributed water is established on the wet shell side, and a flow of ambient air is passed through the wet shell side to form a resulting stream of moist air. A flow of ambient air is passed through the dry tube side and a resulting stream of dry cooled air is recovered. The streams of moist and cooled air are combined and the resulting stream of combined air is discharged into the exterior of the structure. The structure is not hermetically sealed and the water consumption rate is generally less then conventional evaporative cooler.
Abstract:
A fresh air heating unit has a casing (2) containing a stale air flow path (25) and a fresh air flow path (14). Combusted gas products from a gas burner (29) are mixed with the fresh air to heat it to a desired temperature before it is discharged into an enclosure. The two paths extend through a heat exchanger (15) and the rate of flow of stale air driven by a fan (26) through the casing is substantially equal to the rate of flow of fresh air driven through the casing by a second fan (21). As the rate of flow of fresh air from the casing into an enclosure is substantially matched by the rate of flow of stale air from the enclosure, and heat is transferred between the two air flows by the heat exchanger (15), a total replacement of air in the enclosure at a relatively high rate can be sustained in an economically viable manner. The level of noxious combustion products in the enclosure and produced by the gas burner (29) can thus be kept beneath that regarded as harmful by health authorities.

Abstract:
The present invention provides a simple pre-cooling system and method for pre- cooling air. The pre-cooling system comprising a first stage sensible cooling means for exchanging sensible heat indirectly between water and air to cool air and raising the temperature of the water and a second stage adiabatic cooling means for cooling the air adiabatically by direct contact of water with sub-cooled air from the first stage sensible cooling means. In the method for pre-cooling air, atmospheric air and water indirectly contacted for exchanging sensible heat to cool air and heat water, and directly contacting water and cooled air for adiabatic cooling of cooled air and water wherein air and water are cooled to wet bulb temperature lower than ambient wet bulb by evaporation of less quantity of water.

Abstract:
A multi-stage hybrid evaporative cooling system is described as having a direct evaporative cooling subsystem and an indirect evaporative cooling subsystem having one of a horizontal and a vertical set of heat exchanger channels. The multi stage hybrid evaporative cooling system with a horizontal set of heat exchanger channels has a portion of the horizontal heat exchanger channels partially extended into a next stage of the multi-stage system. The multi-stage hybrid evaporative cooling system with the vertical set of heat exchanger channels includes a first set of vertical set of heat exchanger channels spanning a substantial vertical height of the stage of the hybrid evaporative cooling system, and a second set spanning approximately half the height of the stage. The multi-stage hybrid evaporative cooling system further includes a refrigeration system for lowering the temperature of the indirect evaporative cooling subsystem air without affecting its pressure flow.
