This study outlines the implementation of compressor less refrigerator with peltier module. Compared to conventional refrigeration systems thermoelectric refrigeration based on the Peltier effect, does not require any compressor, expansion valves, absorbers, condensers or solution pumps. Moreover, it does not require working fluids or any moving parts, which is friendly to the environment and results in an increase in reliability. It simply uses electrons rather than refrigerants as a heat carrier. Nowadays, thermoelectric refrigeration devices have a distinct place in medical applications, electronic applications, scientific equipment and other applications, where a high-precision temperature control is essential. The device is powered by a Non-conventional energy resource, here PV Cells. The difference between the existing methods and this model is that a thermoelectric cooling system refrigerates without use of mechanical devices (Conventional Condenser fins and Compressor) and without refrigerant too. Since the Peltier module is compact in size, refrigeration or heating system can be designed according to the user's requirements (in desired size and shape).
: In recent trends with increase awareness towards environmental pollution due to to the production, use and discharge of cholorofloro carbon (CFC) and Hydrocholorofloro carbon (HCFC) as a refrigerant for heat carrier in conventional refrigeration system has become a subject of great concerned and result in extension research into development of refrigeration technology. Thermoelectric Refrigeration is new era as alternative because it can convert waste electricity into useful cooling, is expected to play an important role in today's refrigeration system. In this project we have use thermoelectric module for cooling and heating effect the precise develop cooling power below which the thermoelectric method is preferable thermoelectric cooler is solid state heat pump which uses semiconductor material by peltier effect,to provid intaneous cooling or heating.It has the advantage of having no moving parts like compressor, condenser, evaporator and dust maintenance free. The thermoelectric refrigeration have been design and developed an experimental thermoelectric refrigeration system having refrigeration space of 2.5 lit is cooling by three module and heat sink fan assembly for thermoelectric module to increase heat dissipation rate . The rejected heat has been utilized for piazza heating I. INTRODUCTIONThe basic concept behind thermoelectric (TE) technology is the Peltier effect-a phenomenon first discovered in the early 19th century. The Peltier effect occurs whenever electrical current flows through two dissimilar conductors. Depending on the direction of current flow, the junction of the two conductors will either absorb or release heat. Explaining the Peltier effect its operation in thermoelectric devices, is a very challenging proposition. It ultimately keys on some very complex physics at the sub-atomic level. Here we will attempt to approach it from a conceptual perspective with the goal of giving readers an intuitive grasp of this technology.
Today’s market is getting progressively doused step by step, customer ending up progressively self important and hard to persuade that one will offer same value they are searching for, Lean Manufacturing has a route in front of rivalry by envisioning and upgrading the value stream. Value stream mapping (VSM) is a tool in lean execution. It is a strategy to investigate the present condition of procedure and assessing a future condition of the procedure. It takes an item or administration from its start through to end client by lessening waste contrasted with current mapping. In this paper, the first Value stream mapping of the current condition of the procedure is dissected for a situation organization and consequently, the future Value stream map was proposed base on lean standards. In light of the last outcomes, it tends to be the reason that value stream mapping is a helpful apparatus for decreasing waste and non-value included activities
