Exploitation of solar energy is becoming increasingly popular thanks to the potential saving on energy costs and to widespread environmental friendly policies. In this context, solar cooling is particularly interesting since greater cooling loads are usually needed in areas where the solar...

The most commonly employed technology for cold production is vapour compression, mainly due to the high efficiency of such devices. However, a major operating issue is the strong dependency of system efficiency and capacity on ambient temperature, which in turn leads to low yearly performance...

The increasing diffusion of renewable energy sources are posing new challenges to the power grid due to their intrinsic unpredictability causing poor power quality, line congestion and unreliable and unsecure grid operations. In the future, power grid operators may require to the...

A diffuse interest on cycle modifications for R744 applications that allow to achieve better CO2 cycles performance can be inferred from the literature. The parallel compression cycle in flash tank configuration seems to be an interesting solution and the authors conducted an experimental...
