International Classification:

G06F 17/30

US Classification:

705007000

Abstract:

Systems and methods for asset data collection, presentation, and management. In one general aspect, a Web portal provides a centralized end-to-end view of IT operations of an organization. The portal may, for example, provide an organization's view of operations and asset data. Visibility of accurate data on an organization-wide scale allows managers to spot issues immediately, respond quickly, and offer continuous improvement.

US Patent:

51813882, Jan 26, 1993

Filed:

Nov 5, 1991

Appl. No.:

7/787833

Inventors:

Anthony W. Abraham - Arlington TX

Assignee:

Wynn's Climate Systems, Inc. - Ft. Worth TX

International Classification:

F25B 4500

US Classification:

62 77

Abstract:

A refrigerant recovery apparatus has a feature for purging an air conditioning system component for cleaning. The air conditioning component will be connected into the recovery unit at a point where it will receive liquid refrigerant from the recovery unit. This liquid refrigerant comes from the storage container, with pressure being maintained by the use of the compressor. The air conditioning component connects to a purge container, which is separate from the storage container. The purge container has an outlet leading to an expansion valve for converting the purged refrigerant into a vapor. The vapor refrigerant leads back to a suction end of the recovery unit.

Nov 29, 1990

Appl. No.:

7/621251

Inventors:

Anthony W. Abraham - Arlington TX

Assignee:

Wynn's Climate Systems, Inc. - Ft. Worth TX

International Classification:

F25B 4500

US Classification:

62292

Abstract:

A refrigerant recovery apparatus has a combination heat exchanger which both serves as a condenser and evaporator. The heat exchanger has spaced apart headers, each header having a plurality of holes. Finned evaporator tubes and finned condenser tubes extend between the headers. The tubes are parallel to each other and perpendicular to the header. A fan blows air through the evaporator. Refrigerant fluid flows through the condenser and evaporator sections of the heat exchanger. The water condensate formed in the evaporator section will evaporate as a result of the heat from the condenser section. In one embodiment, the evaporator tubes are sandwiched between condenser tubes on the forward and rearward sides of the heat exchanger. In another embodiment, the evaporator tubes are located above the condenser tubes.

Appl. No.:

7/908396

Inventors:

Anthony W. Abraham - Arlington TX

Assignee:

Wynn's Climate Systems, Inc. - Fort Worth TX

International Classification:

F25B 4500

US Classification:

62292

Abstract:

A refrigeration system servicing apparatus includes a digital controller, a vessel for storing and pressurizing refrigerant, a solenoid actuated valve responsive to the digital controller for selective connection of the refrigeration system to a vacuum source, a solenoid actuated valve responsive to the digital controller for connection of the vessel to the refrigeration system, a pressure sensor for providing pressure readings to the digital controller from the low pressure side of the vacuum source, a pressure sensor for providing pressure readings to the digital controller from the vessel and means for quantifying the refrigerant in the Vessel. Three operational modes provided for are: a "vacuum" mode, during which residue material in the refrigeration system is boiled away; a "charge oil" mode, during which lubricant is added to the refrigeration system; and a "charge refrigerant" mode, during which refrigerant is added to a refrigeration system. During vacuum mode the refrigeration system may be subjected to a pressure integrity test. Where in an inadequate vacuum is developed the error condition is signalled and the service technician is given opportunity to attempt correction.

Filed:

Apr 21, 1993

Appl. No.:

8/051088

Inventors:

Anthony W. Abraham - Arlington TX

Assignee:

Wynn's Climate Systems, Inc. - Ft. Worth TX

International Classification:

F28F 1308

US Classification:

165174

Abstract:

A parallel flow heat exchanger has perforated webs within its tubes. The tubes are parallel to each other and extend between headers. Each tube has webs located within it which define flow passages. The webs are perforated along the length to communicate refrigerant flow in one passage with that of refrigerant flow in other passages. The flow tubes are extruded integrally. The perforations are formed by air jets mounted in the extrusion die cores.

Appl. No.:

8/027200

Inventors:

Anthony W. Abraham - Arlington TX

Assignee:

Wynn's Climate Systems, Inc. - Ft. Worth TX

International Classification:

F28F 922

US Classification:

165173

Abstract:

The air conditioner condenser includes a set of hollow parallel tubes disposed between a pair of header pipes. The header tubes provide fluid flow between the header pipes and are substantially flat, having parallel upper and lower side walls. The walls have inner and outer surface and are separated by longitudinally extending webs defining separate flow passages. A partition or baffle is formed by removing one of the upper or lower walls from a tube having a length greater than that of the other tubes. The header pipe has a series of slots, each having similar dimensions. The tubes are inserted into the slots and sealed, with the extended portion of the extended tube forming the partition or baffle.

Appl. No.:

7/540186

Inventors:

Anthony W. Abraham - Arlington TX

Assignee:

501 Wynn's Climate Systems, Inc. - Ft. Worth TX

International Classification:

F25B 4302

US Classification:

62470

Abstract:

A refrigerant recovery apparatus has features for trapping oil recovered from an air conditioning system. It has a low pressure oil separator which is mounted in line with the flow of refrigerant on the suction side of the compressor. The low pressure oil separator will be located at a lower elevation than the compressor. When the compressor is turned off, this allows excess oil in the compressor to drain to its design level.
