About This PhD Project

Project Description

Context
The project consists in the study of energy conversion technologies in innovative refrigerant -based district heating systems. These systems transport energy from the heat production units (e.g. cogeneration plants, geothermal heat exchangers) to the buildings through latent heat of vaporization. This reduces the volume of fluid that circulates in the network, and thus reduces the energy consumed for pumping and material costs due to smaller required piping sizes.

As the fluid in district heating systems is usually water, the use of refrigerant will affect the expected efficiency of the energy conversion systems for the production of heat in the network as well as for the exchange of heat between the network and the buildings. The candidate will develop simulation models to predict the energy efficiency of energy conversion systems in refrigerant-based district systems, perform an energy efficiency analysis of refrigerant-based district systems, and draw recommendations for the design and operation of these systems.

Qualifications
Experience and skills in the following fields are major assets: thermodynamics (refrigeration), simulation of building energy systems, object-oriented programming (Python, Modelica). Proficiency in English (written and oral) is essential.

Application
Applications should include: (1) curriculum vitae, (2) academic transcripts, (3) letter of motivation and (4) sample of a technical text written in English.
