Different ethyl alcohol secondary fluids used for GSHP in Europe

Ethyl alcohol based secondary heat transfer fluids are typically used in ground source heat pumps (GSHPs) in Sweden because of their attractive thermophysical properties and low toxicity. Denaturing agents must be added to ethyl alcohol based secondary fluids, and in Europe, the most commonly used ...

Ethyl and isopropyl alcohol blends as alternative secondary fluids

Methyl and ethyl alcohol have good thermophysical characteristics for use in refrigeration systems. The purpose of this study was to measure the thermal conductivity of ethyl and methyl alcohol solutions to determine if they can become competitive secondary fluids. A Thermal Constants Analyzer measured the ...

Investigation of ethanol based secondary fluids with denaturing agents and other additives used for borehole heat exchangers

Borehole heat exchangers are used in conjunction with ground source heat pumps in Nordic countries. Aqueous ethanol solutions are commonly used with other secondary fluids such as water in borehole heat exchangers to decrease the freezing point of the liquid. However, ethanol based mediums contain ...

Combined effect of physical properties and convective heat transfer coefficient of nanofluids on their cooling efficiency

The authors have developed a model for the estimation of how a nanofluid will work as a coolant without having to perform a number of experiments. The nanofluids used in the study were four water based metallic oxides. These nanofluids were compared to water in ...
