US Patent:

6889179, May 3, 2005

Filed:

Sep 6, 2001

Appl. No.:

09/947724

Inventors:

Xiaoyuan Chang - Manlius NY, US
Sandra Jayne Downey - Cazenovia NY, US

Assignee:

Carrier Corporation - Syracuse NY

International Classification:

G06F007/48

US Classification:

703 6

Abstract:

An environmental simulation test utilizes various temperatures and exposure times while exposing a test item to wet and dry conditions. In one example a marine environment where there is some pollution is simulated using a 24 hour test cycle that may be repeated as many days as necessary. The test cycle includes spraying a solution onto a test item and then cyclically exposing the test item to dry and humidified conditions.

Appl. No.:

10/011424

Inventors:

Sandra Downey - Cazenovia NY, US
Daniel Gaffaney - Chittenango NY, US
Thomas Garosshen - Glastonbury CT, US

International Classification:

F28F013/18

US Classification:

165/133000

Abstract:

An article having a first member formed from a first metal and a second member connected with the first member at a contact area. The second member is formed from a second metal having high reduction reaction kinetics and galvanic corrosion driving force relative the first member, wherein the second metal is more noble than the first metal. A material for substantially eliminating the galvanic corrosion problem by reducing the reduction reaction kinetics of the second metal in the presence of an electrolyte is provided between the first and second metals. In a preferred embodiment, the article is a heat exchanger wherein the first member is a fin collar and the second member a tube and the material for reducing is a coating on the tube has low reduction reaction kinetics relative to copper for reducing corrosion activities between the tube and fin collar.

Appl. No.:

8/435930

Inventors:

Sandra J. Downey - Cazenovia NY

Assignee:

Carrier Corporation - Syracuse NY

International Classification:

C09K 504
F25B 1500

US Classification:

252 68

Abstract:

A corrosion inhibiting working fluid for absorption refrigeration systems and a method of manufacturing such a fluid. The fluid is an aqueous solution of a halogen salt of lithium or ammonia to which are added water soluble compounds containing molybdates, borates and, in a preferred embodiment, silicates. Preferred concentrations of the resultant molybdenum, boron and silicon ions are disclosed. A water soluble compound containing a hydroxide is also added to produce an alkaline normality. In a preferred method of manufacture, the additive compounds are added to the working fluid as aqueous solutions.
