Numerical analysis of the combination of radiative collectors and emitters to improve the performance of water-water compression heat pumps under different climates

Radiative cooling allows to cool down surfaces in a renewable way. It can be combined with solar collection functionality produce heat and cold single device known as Collector Emitter (RCE). In this paper we propose combine RCE compression pumps improve its performance, producing both cold. Two systems are studied: peak load shifting configuration where radiative production for demand occur simultaneously, decoupled an intermediate tank. The research numerically simulates different cities climates, compares them reference system based on conventional pump. results reveal improvement of the performance configurations: greater pump is found tank configuration; but after considering electrical consumptions all components system, configurations exhibit best most cities. Denver, Lleida Rome – dry climate moderate requirements top greatest performance. heating mode, facilities show underutilization field.
