P.S.Ravi , Dr Arkanti Krishnaiah , Dr Suresh Akella , Dr Md. Azizuddin

In all refrigeration and air conditioning equipment the evaporator is either a plate and fin evaporator, tube and fin or a plate and tubular evaporator. There were little changes in manufacturing methods and geometry. This paper presents a new design of evaporator, in which roll bond evaporator is used in room air conditioner. Presently the use of roll bond evaporator is limited to domestic refrigerators only. The study throws light on evaluating the inside heat transfer coefficient ( refrigerant side) of the roll bonded evaporator using R-22 as Refrigerant
