Abstract
Due to more stringent environmental legislation over the years, the automotive sector seeks alternatives to reduce the emission of pollutants. The air conditioning system consumes a good deal of energy from the combustion engine. This work presents a comparative analysis of conventional and an air conditioning with water-cooled condenser using R134a and R1234yf. In order to evaluate the performance of the conventional air conditioner and the water-cooled condenser a steady-state model was developed using the Equation Engineering Solver (EES). The model uses empirical correlation obtained from performance map provide by manufacture to evaluate the effectiveness of the heat exchangers, the mass flow rate and the power consumption of the compressor. The results show that COP and cooling capacity of water-cooled condenser is smaller than air-cooled condenser. In addition, the R134a has a COP 20% higher than R1234y, difference that are in the range found in the literature. The Cooling Capacity of R1234yf is lower than R134a.
