Type of article: Article, IJR article

Summary

The properties of aqueous fluid of potassium formate were studied theoretically and experimentally in order to find an improved secondary refrigerant fluid for indirect refrigeration systems. The most important advantages compared to the traditional aqueous solutions of alcohols and glycoles are good thermodynamic properties, low toxicity and non-flammability. A remarkable benefit is a reduced change of a laminar flow. Volumetric heat is lower, which brings about a higher rate of mass flow, if the temperature change of the fluid is maintained constant. However, because of the clearly lower values of viscosity, the pumping power demand is at same level. Good thermal conductivity promotes good heat transfer.
