Offer Description
RESEARCH PROJECT
Natural Refrigerant technologies for Ultra-Low Temperature Cooling (NAR-ULT)
PRINCIPAL INVESTIGATORS
Prof. Rodrigo Llopis and Prof. Daniel Sánchez
LOCATION
Thermal Engineering Research Group
Mechanical Engineering and Construction Department
Jaume I University
Castellón de la Plana – Spain
DESCRIPTION
The candidate will conduct PhD doctoral studies in Jaume I University. Requirement is to obtain the PhD grade in three to four years.
The candidate will be involved in NAR-ULT project, which aims to develop experimentally high-efficient ultra-low temperature systems using only natural refrigerants. Target of the project is to develop and validate experimentally at least two prototypes achieving -150ºC in the refrigerated space.
The research will focus on advanced modelling of ULT refrigeration architectures, design of the test rigs, building of prototypes, monitoring, testing and evaluation of performance. High level of refrigeration is required to contribute to the project.
Candidate will join a multidisciplinary team with high expertise in refrigeration using natural refrigerants (centralized, commercial, ultra-low temperature, cryogenics) and heat pumps. Group is highly international.
