Benefits of technology
[0012] The present invention accordingly has as one object to provide an improved heat exchanger design which improves and facilitates the heat transfer effect achieved within the condenser section of the heat exchanger.
[0014] Another object of the invention is to provide an improved air conditioning system which utilizes a condenser section having both a water cooled sub section and an air cooled sub section to provide, improved operating efficiency, redundancy, and the ability to operate in cold ambient conditions where freezing might otherwise inhibit the use of water cooling.
[0015] Another object of the invention is to provide a condenser circuit for an air conditioning system having both water and air cooled subsections, in which the water cooled sub section is always located before the air cooled subsection to provide an initial cooling effect using water, thereby increasing the efficiency of the system.
[0025] In the method of the invention an air conditioning apparatus is provided wherein a refrigerant is circulated between a condensing heat exchanger and an evaporating heat exchanger in a refrigerant circuit by a compressor. The efficiency of the apparatus is improved by providing both a water cooled subsection and an air cooled subsection in a redundant arrangement as a part of the condensing heat exchanger, and by providing a by pass means for alternately directing the flow of refrigerant in the refrigerant circuit through either or both of the water cooled subsection and the air cooled subsection of the condensing heat exchanger.
Problems solved by technology
This unit is a purely water cooled unit which fails to offer redundancy in the form of an auxiliary water coil in addition to the air coil.
Purely water cooled units are also more likely to fail due to maintenance requirements.

Embodiment Construction
[0037] The refrigerant based heat exchange system of the invention can be utilized to improve the efficiency of a conventional refrigerant type air conditioning system where a refrigerant such as Freon is circulated by compressor between an evaporator section and a condenser section, wherein it is respectively changed between liquid and gaseous states to effect cooling in the evaporator unit.
[0038] The conventional Freon type air conditioning circuit includes a compressor, condenser, a metering device and an evaporator connected in series in a refrigerant circuit. The system is charged with refrigerant, which circulates through each of the components in order to remove heat from the evaporator and transfer heat to the condenser. The compressor compresses the refrigerant from a low pressure superheated vapor state to a high pressure superheated vapor state, thereby increasing the temperature and pressure of the refrigerant. The refrigerant medium leaves the compressor and enters the...

The present invention comprises an improved refrigerant based heat exchange system useful in air conditioning and refrigeration applications. Improved heat transfer capability is achieved by using a dual heat exchanger with two different heat-transfer mediums, air and water, in one condenser unit and by advancing the water transfer medium ahead of the air transfer medium. Bypass controls are provided for bypassing a selected heat exchange section of the system depending upon existing environmental conditions. The system is optionally housed in a decorative facade which provides an exposed surface adorned with esthetically pleasing artwork.
Description
CROSS-REFERENCE TO RELATED APPLICATIONS [0001] The present application claims priority from a provisional application Ser. No. 60 / 654,618, filed Feb. 17, 2005, by Eric Barger, entitled “Heat Exchanger For Evaporative Cooling Refrigeration System.”BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates generally to refrigerant based heat exchange systems employing a compressor, a condenser, an evaporator and associated fluid circuitry used for air conditioning, food storage refrigeration, and similar applications, and to improvements in the condenser sections of such systems. [0004] 2. Description of the Prior Art [0005] In a typical commercially available air conditioning or refrigeration unit, a condensable refrigerant is compressed, condensed, cooled and then supplied to a metering device and evaporator for cooling a surrounding environment. The condensers of such refrigeration systems are usually cooled by ambient air or by water supplied...
