| Abstract | Currently, the refrigerant used in the automotive air conditioning system is R134a which has a high global warming potential (GWP) value, so people are eager to find a good replacement for it. According to recent studies, R1234yf is considered as one of the top candidates to replace R134a. In this article, the performances of R1234yf “drop-in” system and the optimization to the R1234yf system are experimentally studied and investigated. The expansion valve used for the R1234yf system is optimized by changing the charged fluid and adjusting the spring force. The results indicate that it can improve the performance of R1234yf system significantly through adjusting the thermostatic expansion valve. For the thermostatic expansion valves (TEVs) charged with R134a in thermal bulb, the system performance is optimal. Compared to the original expansion valve, for the R1234yf system applying the adjusted expansion valves, under different working conditions the cooling capacity increases by 11.3% averagely and the coefficient of performance (COP) increases by 8% averagely. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
