International Classification:
F25B 9/00
US Classification:
62 87, 62116

US Patent:
8220277, Jul 17, 2012
Filed:
Aug 20, 2007
Appl. No.:
11/841152
Inventors:
John T. Dieckmann - Belmont MA,
Detlef Westphalen - Roslindale MA,
Assignee:
Tiax LLC - Cambridge MA
International Classification:
F25D 17/06
F25D 11/00
F25B 1/00
US Classification:
62 93, 62 89, 62 90, 62 91, 62 92, 62430, 62498
Abstract:
Recuperation systems and methods are applied to vapor compression cycles in dehumidification, such as in air conditioning. In some embodiments, a method for dehumidification includes introducing a refrigerant from a heating unit to a cooling unit along a first path; introducing the refrigerant from the cooling unit to the heating unit along a second path different from the first path; introducing the refrigerant from the heating unit to the cooling unit along a third path different from the first path; and contacting the cooling unit and the heating unit with a first gas stream.
