METHOD FOR TRANSFERRING HEAT
Document Type and Number:
WIPO Patent Application WO/2012/032106
Kind Code:
A1
Abstract:
The present invention pertains to a process for transferring heat, said process comprising the following steps: (1) transferring heat from a body to a first heat transfer system by means of a secondary loop passageway comprising a heat transfer fluid and, optionally, (2) transferring heat from a second heat transfer system, said second heat transfer system being the same as or different from said first heat transfer system, to said body by means of said secondary loop passageway comprising said heat transfer fluid, wherein: - said secondary loop passageway comprises at least one polymer sealant selected from a rubber seal and a plastic pipe; and - said heat transfer fluid comprises one or more linear perfluoropolyethers having formula (I) here below: RF-(OCF2)n(OCF2CF2)m(OCF2(CF2)zCF2)p-ORF (I), wherein RF, equal or different at each occurrence, is a C1-C3 perfluoroalkyi group, m, n and p, equal to or different from each other, are integers comprised between 0 and 100, preferably between 0 and 50, the sum m+n being higher than 0, and z is equal to 1 or 2, and wherein said heat transfer fluid is circulated through said secondary loop passageway in step (1) for transferring said heat from said body to said first heat transfer system and, optionally, in step (2) for transferring said heat from said second heat transfer system to said body.
