Alternative blends of CO2 for transcritical refrigeration systems. Experimental approach and energy analysis
Elsevier (2023-02-10)As a natural refrigerant, Carbon Dioxide (CO2) has been extended in almost all refrigeration fields due to its environmental friendliness, high availability, and high technological development in the main components of the ... -
Alternative CO2-based blends for transcritical refrigeration systems
Elsevier (2023-03-21)The extensive use of CO2 in commercial refrigeration system has grown in the last two decade thanks to the development of new components and configurations that allows working in transcritical conditions efficiently. ... -
Experimental evaluation of alternative CO2-based blends for transcritical refrigeration systems
International Institute of Refrigeration (IIR) (2023-08-21)This work presents two refrigerant CO2 blends with R32 and R1270 designed with a theoretically nonflammability and a GWP below 150. Both mixtures were tested in a small-capacity vapour compression system with and without ... -
Experimental evaluation of the CO2-based mixtures CO2/R32, CO2/R1234yf and CO2/R1270 in a transcritical refrigerating plant considering the effect of the internal heat exchanger (IHX)
Elsevier (2024-01-05)Using CO2 mixtures results in a simple but effective solution to increase the critical temperature of CO2 and reduce its working pressures. However, the overall effect of these mixtures on the global performance of the ... -
Refrigerant R32 as lower GWP working fluid in residential air conditioning systems in Europe and the USA
Elsevier (2017)Because air conditioning and heat pump systems contribute greatly to greenhouse gas emissions, equipment with both lower global warming potential (GWP) working fluids and a higher level of performance should be used. R32 ... -
Two parallel systems: the political economy of enclosures and open fields on the plains of Västergötland, Western Sweden, 1805-65
(2018-12)Una de las contradicciones de los cercamientos es que promovieron, al tiempo que amenazaron, los derechos de la propiedad. El objetivo de las reformas era establecer una propiedad de la tierra moderna y absoluta, proyecto ...
