Abstract

Pendinginan merupakan proses pengambilan panas, sehingga terjadi penurunan suhu lingkungan dan menjaga suhu tersebut selama waktu yang diinginkan. Terdapat beberapa system pendinginan yang digunakan namun system pendingin kompresi uap merupakan pendinginan yang umum digunakan karena mudah diterapkan. Sistem ini terdiri dari kompresor, katup ekspansi, kondensor dan evaporator. Fluida kerja yang digunakan dalam proses pendinginan disebut sebagai refrigeran. Pada laboratorium konversi energy terdapat air conditioner test-bed hasil rekayasa terdahulu yang kinerjanya masih belum sesuai dengan harapan dikarenakan beberapa hal, menyangkut instalasi equipment dan instrument. Rancang bangun dilakukan guna mengevaluasi letak sumber permasalahan, merancang dan menginstalasi beberapa peralatan dan instrument agar mendapatkan kinerja system atau performa yang lebih baik. Pendekatan teoritis dan praktis dilakukan untuk mengkaji dan menyelesaikan permasalahan tersebut, dan ternyata mampu menghasilkan kinerja test-bed yang lebih baik dibanding sebelumnya yaitu 4,35 dan COP pada alat yang sekarang sebesar 4,45. Kata kunci : air conditioning test-bed, refrigerant, suhu Refrigeration is a heat removal process, resulting in a decrease in ambient temperature and maintain that temperature for the desired time. There are several cooling systems that are used,but the vapor compression refrigeration system is cooling a commonly used because it is easy to implement and easy to analyze its effectiveness. This system consists of a compressor, expansion valve, condenser and evaporator. Working fluid used in the cooling process referred to as a refrigerant. In the energy conversion laboratory there is an air conditioner test-bed, results of previous engineering process whose performance is still not in line with expectations due to several things, involves the installation of equipment and instruments. Design was conducted for evaluating the location of the source of problems, designing and installing some equipment and instruments to obtain system performance or better performance. Theoretical and practical approach is to examine and resolve these problems, and was able to produce test-bed performance better than before the previous 4,35 and COP on the tools thatare now at 4,45. Keyword : air conditioning test-bed, refrigerant, temperature.
