Investigation and optimization of a CO2-based polygeneration unit for supermarkets

Multi-Objective Optimization of a Solar Combined Power Generation and Multi-Cooling System Using CO2 as a Refrigerant

“…The supercritical CO 2 cycle is compatible with a wide range of heat sources, particularly renewable energy, and it is also used in combined cooling, power, and heating systems [49]. Over the years, various configurations of the supercritical CO 2 cycle have been developed, making it an increasingly promising technology for power generation [50,51].…”

Holistic renovation of a multi-family building in Greece based on dynamic simulation analysis

“…The storage tank which is connected to the solar thermal system receives the heat inputs from the solar field, stores a part of its quantity and feeds the building with DHW, while there is also a small thermal loss percentage to the ambient. Therefore, it can be written as below (Lykas et al, 2022):…”

“…Where ( Qload ) is the load heat demand, ( Qloss ) is0307 the tank thermal losses and ( Qst ) is the stored energy in the tank which can be written as below (Lykas et al, 2022):…”

Residual energy use and energy efficiency improvement of European supermarket facilities during the post-COVID and energy crisis period

“…Based on the establishment's useful area, electricity consumption values range from 440 to 600 kWh/m 2 ·year, depending on the local weather conditions [ 38 ]. As a result, modern supermarket companies account for 3 %–5 % of the world's total electricity consumption [ 39 ].…”
