Abstract
This paper presents an experimental analysis of an Ebidon® TAABTM: Air Conditioning Lab unit running on R-134a being compared with R22 and R404 refrigerants, a $24,449 piece of equipment purchased by the JMU ISAT Department. In this paper we will compare the performance of the R-134a refrigerant under a range of working conditions and compare them to how the system would run on R22 or R404. The experimental tests use varying fan speeds and the R-134a data collected is compared to simulated data collected for R22 and R404. Analysis of the collected data and simulated data will be compared on the basis of COP and the systems effectiveness to add or remove heat from the air. From testing the system it is seen that R134a has the higher COP, R22 has the highest heat transfer, air heat transfer as fan speed increases and R134a has the highest, realistic heat transfer effectiveness under same refrigerant-side temperature and pressure testing conditions.
