1. A heat transfer fluid, comprising:
25 wt % to 90 wt %, relative to a weight of the heat transfer fluid, of at least one hydrogen bond donor having a molecular weight of 60 g/mol or more and a first heat capacity, the at least one hydrogen bond donor comprising 1.0 wt % or more of hydrogen bond donor functional groups relative to the molecular weight of the at least one hydrogen bond donor; and
10 wt % to 75 wt %, relative to a weight of the heat transfer fluid, of at least one hydrogen bond acceptor having a molecular weight of 60 g/mol or more and a second heat capacity, the at least one hydrogen bond acceptor comprising 1.0 wt % or more of hydrogen bond acceptor functional groups relative to the molecular weight of the at least one hydrogen bond acceptor; and
an electrical conductivity of the heat transfer fluid being 2.0 μS/cm or less,
wherein, a) the hydrogen bond donor does not contain hydrogen bond acceptor functional groups, or b) the hydrogen bond donor comprises one or more hydrogen bond acceptor functional groups, and 10 wt % or more of the hydrogen bond acceptor functional groups in the hydrogen bond acceptor, relative to the molecular weight of the hydrogen bond acceptor, are different from the hydrogen bond acceptor functional groups in the hydrogen bond donor, and
i) wherein the hydrogen bond donor comprises at least one hydrogen bond donor selected from the group consisting of an alcohol, a carboxylic acid, a polycarboxylic acid, a primary amine, a secondary amine, and any combination thereof, and wherein the alcohol comprises:
an alcohol comprising a single alcohol functional group, a linear alkylene glycol, a polyol, a polyalkylene glycol, an ether alcohol, a hydroxyl group-terminated polyether, a hydroxyl group-terminated polyalkylene glycol ether, a hydroxyl group-terminated polyester, and any combination thereof; and
ii) wherein the hydrogen bond acceptor comprises at least one hydrogen bond acceptor selected from the group consisting of an ether, a polyether, an ester, a polyester, a ketone, an aldehyde, a carbonate, a phosphite ester, a phosphate ester, a tertiary amine, and any combination thereof.
