This paper examines the compression of heat loss by the refrigerant in the condenser, the compressor’s input power requirement, the coefficient of performance, and the mass and volume flow rates of various refrigerants in a chiller plant at SVNIT, Surat. Operational data from the chiller plant were utilized, with R-134a currently used as the refrigerant. Data computations for alternative refrigerants—R-408A, R-402A, R-507, and R-152A—were performed using CoolPack software. The results show that the compressor power consumption for R-134a is 34.05%, 18.65%, and 15.04% lower than that for R-408A, R-402A, and R-507, respectively, but 5.14% higher than R-152A. Regarding heat loss in condenser, R-134a shows 5.01%, 2.72%, and 2.21% lower compared to R-408A, R-402A, and R-507, respectively, but 0.75% higher than R-152A. The volume flow rate of R-152A is higher than that of R-134a, which necessitates a larger system size. While R-152A achieves the highest COP, R-134a provides 26.81%, 15.57%, and 12.9% higher COP compared to R-408A, R-402A, and R-507, respectively, but 5.53% lower than R-152A. The COP values for R-134a are reported as 6.1 and 5.78. However, due to the flammability of R-152A and the larger system size it requires, R-134a remains the preferred refrigerant for chiller plants, despite the higher COP of R-152A.

摘要

This paper examines the compression of heat loss by the refrigerant in the condenser, the compressor’s input power requirement, the coefficient of performance, and the mass and volume flow rates of various refrigerants in a chiller plant at SVNIT, Surat. Operational data from the chiller plant were utilized, with R-134a currently used as the refrigerant. Data computations for alternative refrigerants—R-408A, R-402A, R-507, and R-152A—were performed using CoolPack software. The results show that the compressor power consumption for R-134a is 34.05%, 18.65%, and 15.04% lower than that for R-408A, R-402A, and R-507, respectively, but 5.14% higher than R-152A. Regarding heat loss in condenser, R-134a shows 5.01%, 2.72%, and 2.21% lower compared to R-408A, R-402A, and R-507, respectively, but 0.75% higher than R-152A. The volume flow rate of R-152A is higher than that of R-134a, which necessitates a larger system size. While R-152A achieves the highest COP, R-134a provides 26.81%, 15.57%, and 12.9% higher COP compared to R-408A, R-402A, and R-507, respectively, but 5.53% lower than R-152A. The COP values for R-134a are reported as 6.1 and 5.78. However, due to the flammability of R-152A and the larger system size it requires, R-134a remains the preferred refrigerant for chiller plants, despite the higher COP of R-152A.
