Description Cooling systems account for nearly 20% of electricity consumption and 10% of greenhouse gas emissions, globally. With demand for cooling expected to grow tenfold by 2050, and the increasing frequency of extreme heat waves, improving the efficiency of cooling systems plays a critical role in addressing the global climate challenge. Passive Radiative Cooling (PRC) materials that can dissipate heat as infrared radiation, have recently emerged. This thesis project aims to define - by means of lumped-parameter models based on experimental evidence - the figures of merit and testing conditions enabling the standardised evaluation of their cooling performance on-site and potential energy saving that could derive from such technologies. In detail, the thesis will aim to calculate the potential energy savings for the particular case of air source heat pumps enhanced by the sub-ambient cooling capabilities of passive radiative cooling materials, by developing the lumped-element dynamic model of this cooling technology and testing it for the whole summer season.

Required skills Fundamentals of thermodynamics and heat&mass transfer; Familiarity with MATLAB and SIMULINK environment
