The most commonly used cycle in the refrigeration system is VCRS (Vapour Compression Refrigeration System) system. The suction line heat exchanger is employed in vapour compression refrigeration system for protecting system components. It ensures sub cooled liquid refrigerant supplied to expansion device inlet and superheated vapour refrigerant to the compressor inlet. Nano lubricant was added in the compressor to reduce power consumption and increase COP of the system. In the present work suction line heat exchanger is placed in VCRS cycle and nanoparticle (SiO2) with the 0.5% weight concentration was dispersed into the lubricant oil. With the employing of heat exchanger net refrigeration effect increased. Replacing of POE oil with nano lubricant reduces the power consumption and COP of the system increased
