Energetic, economic and environmental (3E) analysis of R290, R454C and R465A for drop-in split type air conditioning running on R22
The present study aims to evaluate the process of drop-in of R22 in split type air conditioning with refrigerant fluids R290, R454C, and R465A. A mathematical model was developed to do an energetic, economic and environmental analysis using different fluids. The mathematical model of the heat exchan...

| description | The present study aims to evaluate the process of drop-in of R22 in split type air conditioning with refrigerant fluids R290, R454C, and R465A. A mathematical model was developed to do an energetic, economic and environmental analysis using different fluids. The mathematical model of the heat exchangers was developed using the moving boundary technique and the compressor was modeled as recommended by the ISO9309 standard. The model was experimentally validated by comparing several results obtained in the laboratory using R22. The average absolute difference between experimental and theoretical results are 3.5%. R465A has cooling capacity 2.5% higher and R290 COP 8.1% higher than R22 in the test condition described by AHRI Standard 210/240. When taking into account cost, efficiency, and environmental effect, R290 is the most suitable replacement for R22 drop-in. R465A is the best option to replace the R22 when taking the cooling capacity results into account. |
