Theoretical Global Warming Impact Evaluation of Medium and High Temperature Heat Pumps Using Low GWP Refrigerants
MDPI (2021-08-01)This study provides a global warming impact analysis of environmentally friendly refrigerants used as replacements for R134a and R245fa. R290, R1234yf, R1234ze(E), R513A and R450A are considered as refrigerants to replace ... -
Thermodynamic Analysis of a CO2 Refrigeration Cycle with Integrated Mechanical Subcooling
MDPI (2020)Different alternatives are being studied nowadays in order to enhance the behavior of transcritical CO2 refrigeration plants. Among the most studied options, subcooling is one of the most analyzed methods in the last years, ... -
Variable speed liquid chiller drop-in modeling for predicting energy performance of R1234yf as low-GWP refrigerant
Elsevier (2018-07)This paper presents a model for a variable-speed liquid chiller integrating a compressor model based on Buckingham π-theorem to accurately predict the system performance when R134a is replaced with R1234yf, using a wide ...
