| 摘要 |
The present invention relates to the application of a non aqueous fluid as heat transfer agent in cooling circuits or heat exchanger heating circuits, this application being characterized in that the non aqueous fluid comprising one or more alkleneglycol monoethers of the general formulae R1O(CH2CHR2O)mH in which m is an integer equal to 1 or 2, R1 is an alkyl radical comprising a number of carbon atoms from 4 to 8 where m=1 , or from 1 to 5 where m=2, and R2 is a hydrogen atom or a methyl radical. The present invention also relates to new compositions based essentially on alkyleneglycol monoether or monoethers, mixed with diols and/or other alkyleneglycol monoethers. |
