43335152, Jun 8, 1982

Filed:

Aug 13, 1980

Appl. No.:

6/177663

Inventors:

William H. Wilkinson - Columbus OH
William T. Hanna - Gahanna OH

Assignee:

Battelle Development Corp. - Columbus OH

International Classification:

F25B 1500

US Classification:

165 1

Abstract:

Sensible waste heat from industrial or other sources is boosted to useful temperature levels by combining at least one Rankine vapor generation cycle with at least one solution heat pump cycle. Waste heat is first utilized to boil off refrigerant in the Rankine cycle evaporator to provide a source of relatively high pressure vapor to an absorber in the solution heat pump. In the absorber, the vapor is contacted with a working solution of absorbent and refrigerant. As the refrigerant vapor is absorbed into solution, its latent heats of condensation and solution are given off at a temperature higher than the temperature of to a process (boosted output) stream the waste heat source. The working solution is then throttled to a relatively low pressure desorber where a portion of the refrigerant is desorbed as vapor from the solution by the further use of waste heat. The desorbed refrigerant vapor is then condensed and pumped to the evaporator for reuse. Working solution is recycled from the desorber to the absorber for reuse.

Assignee:

Gas Research Institute - Chicago IL

International Classification:

F25B 1500

US Classification:

62476

Abstract:

A absorption refrigeration system having cooling and heating modes of operation functions with a double-effect or "split" refrigeration cycle having approximately the same refrigerant concentration span in each cycle loop. The system includes a novel direct expansion combined evaporator and absorber assembly with improved heat transfer characteristics and with interchangeable liquid flows accomplished through actuation of a conventional reversing valve. Also, the system is provided with improved recuperative heat exchangers to further increase system energy conversion efficiencies.

Appl. No.:

6/177660

Inventors:

William H. Wilkinson - Columbus OH
William T. Hanna - Gahanna OH

Assignee:

Battelle Development Corporation - Columbus OH

International Classification:

B01F 304

US Classification:

261140A

Abstract:

Countercurrent flow absorber and desorber devices are provided for use in absorption cycle refrigeration systems and thermal boosting systems. The devices have increased residence time and surface area resulting in improved heat and mass transfer characteristics. The apparatuses may be incorporated into open cycle thermal boosting systems in which steam serves both as the refrigerant vapor which is supplied to the absorber section and as the supply of heat to drive the desorber section of the system.

Appl. No.:

7/475811

Inventors:

William H. Wilkinson - Columbus OH

Assignee:

Battelle Memorial Institute - Columbus OH

International Classification:

F25D 2300

US Classification:

62271

Abstract:

A hybrid air-conditioning system having an absorption refrigeration subsystem for sensible heat loads and a cooperating liquid desiccant dehumidification subsystem for latent heat loads incorporates additional apparatus for effecting the efficient transfer of available heat between the subsystems to improve the total system Coefficient of Performance (C. O. P. ) over a wide range of latent heat load to sensible heat load proportions. Available heat recovery and system internal load generation are utilized in high and low latent load ratio regions, and modulated heat transfer using an additional series absorption refrigeration cycle loop is optionally utilized in the mid-latent heat load ratio region.

Inventors:

William H. Wilkinson - Columbus OH

Assignee:

Gas Research Institute - Chicago IL

International Classification:

F25D 2300

US Classification:

62271

Abstract:

Filed:

Aug 13, 1980

Appl. No.:

6/177680

Inventors:

William H. Wilkinson - Columbus OH

Assignee:

Battelle Development Corporation - Columbus OH

International Classification:

F01K 1706

US Classification:

60648

Abstract:

A system is provided which improves the ability of cogeneration facilities to meet varying electrical power and process steam demands. One or more thermal boosting systems each having a Rankine cycle evaporator coupled with a solution heat pump cycle is integrated with the turbines of the cogeneration facility to maintain full steam flow through the turbines and provide a portion of the process steam demands on the facility. Optionally, a bottoming turbine is added to the system to further improve its flexibility to meet varying demands.

Inventors:

William H. Wilkinson - Upper Arlington OH

Assignee:

Gas Research Institute - Chicago IL

International Classification:

F25B 2702

US Classification:

622383

Abstract:

An absorption refrigeration and heat pump system in which a higher temperature subsystem and a lower temperature subsystem are combined with the desorber means of the higher temperature subsystem in heat exchange relationship with the condenser means of the lower temperature subsystem, and in which the evaporators of each subsystems are in heat exchange relationship with either the load in one mode of operation or the heat sink in another mode of operation, and the absorbers and condenser of the lower temperature subsystem are in heat exchange relationship with the heat sink in the first mode of operation and with the load in the other mode of operation. Means are provided to balance the system including a condensate pump between the higher temperature condenser and the higher temperature desorber. Alternate means are provided to improve lower temperature heat pumping by restricting the refrigerant flow through one of the expansion valves and diverting it to the solution pump.
