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 denaturing agents that can affect the thermal properties of the secondary fluids. In this study, a Thermal Constants Analyzer used the Transient Plane Source method ...
