Refrigeration systems with propane (R290)

In the course of the Ecodesign Directive, increasingly stringent requirements are being placed on liquid chillers with regard to minimum energy efficiency values. In some areas of application, the minimum efficiency values can only be achieved at great expense with conventional systems using conventional partially halogenated hydrocarbons as refrigerants. One way to improve the energy efficiency of such systems is to use propane as a refrigerant. In comparison, propane has good thermodynamic properties and a low climate impact (GWP = 3).

Within the scope of the research project, the novel refrigeration system will be investigated both experimentally and computationally. In the first step, a computational simulation of the new refrigeration system will be carried out based on theoretical preliminary considerations using the EES software. For the experimental investigation, a test bench for the novel refrigeration system will be set up.

Students have the opportunity to participate in the development of the test bench or the experimental investigation of the novel refrigeration system within the framework of project (PA, R & D) and final theses (Bachelor, Master). Open topics can be found under student research or by direct contact with the responsible staff member.
