| Sumario: | [EN] This paper presents a theoretical performance of R1234yf and R152a as possible replacements of R134a in refrigeration systems. The refrigeration system performance using R134a, R1234yf and R152a was carried out for single stage refrigeration system for different evaporating condition ranging from 253 to 283 K and for condensing temperatures of 313 K, 323 K and 333 K holding 5 K as superheating degree and subcooling degree. Refrigerant performance is evaluated using COP, cooling capacity, power consumption and compressor discharge temperature. Results shown that COP increases about 2.47-30.79% using R152a, meanwhile COP decreases about 2.7-18.14% using R1234yf respect to R134a for the condensation and evaporation range studied. |
