US Patent:

44870272, Dec 11, 1984

Filed:

Nov 7, 1983

Appl. No.:

6/549461

Inventors:

Robert A. Macriss - Deerfield IL
Thomas S. Zawacki - Oak Park IL

Assignee:

Institute of Gas Technology - Chicago IL

International Classification:

F25B 1500

US Classification:

62112

Abstract:

A high efficiency space conditioning process and apparatus for heating and cooling utilizing an absorption cycle in the nature of absorption heat pumps for heating and cooling. The invention provides a process and apparatus having a higher Coefficient of Performance than conventional absorption heat pumps by utilization of a substantially saturated salt solution cycle between at least one pair of: (1) an absorber and generator, or (2) a condenser and evaporator, wherein the salt is crystallized to the solid phase in the generator or evaporator, respectively, and the heat of crystallization is utilized for refrigerant vaporization occurring simultaneously.
