We are looking for an ETH student interested in designing and building a suitable experimental setups and cuonducting experimental studies.

With growing populations and economies, the worldwide energy demand for cooling and heating will rise significantly in the upcoming decades. This necessitates the development of efficient and sustainable technologies and heat pumps play a crucial role in achieving this goal. At the Energy and Process Systems Engineering Lab, we focus on enhancing heat pump efficiency through innovative approaches. One such approach involves using mixtures as working fluids to improve efficiency and increase the overall applicability. To achieve this, we are in the process of setting up a fully autonomous lab to measure working fluid properties using spectroscopy to complement our simulations. Additionally, we explore the potential of electrochemical heat pumps, a promising technology that combines elements of a traditional vapor-compression refrigeration cycle with an electrochemical cell. This process significantly reduces compression work by shifting it from the gaseous to the liquid phase. After numerically evaluating the potential of this process, we now aim to set up an experiment to evaluate this process in more detail.

We are looking for an ETH student interested in designing and building suitable experimental setups as well as conducting experiments. Your task is designing (CAD drawings) and constructing of an experimental setup and conducting experimental work.

• Passion for constructive mechanical engineering (CAD, design, and selection of connections, seals, etc.)
• First experience with experimental work, e.g., in the context of a bachelor thesis. Desirable in spectroscopy or electrochemistry but not mandatory
• Technical and practical skills
• Highly motivated with an independent and goal-oriented way of working

The Energy and Process Systems Engineering (EPSE) Group focuses on sustainability in energy and chemical process systems. We develop methods to advance sustainable energy and chemical process systems from the molecular to the systems scale. At EPSE, you will be part of a young and motivated research team.

We look forward to receiving your online application with the following documents:

• CV
• Short Motivational Letter, (max. 300 words)
• academic transcripts

Please note that we exclusively accept applications submitted through our online application portal. Applications via email or postal services will not be considered.
