Energy performance evaluation of R1234yf, R1234ze(E), R600a, R290 and R152a as low-GWP R134a alternatives
文摘
A refrigerating facility was experimentally tested with five low-GWP alternatives. The results had been compared with R134a in the same operating conditions. R290 presented an increment of COP, cooling capacity and compressor power consumption. R152a and R1234yf presented a slight variation in terms of COP and cooling capacity. R600a and R1234ze(E) presented an important reduction in cooling capacity and COP.
