INTRODUCTION

In steam jet refrigeration systems, water can be used as the refrigerant. Like air, it is perfectly safe. These systems were applied successfully to refrigeration in the early years of this century. At low temperatures the saturation pressures are low (0.008129 bar at 4°C) and the specific volumes are high (157.3 m3/kg at 4°C). The temperatures that can be attained using water as a refrigerant are not low enough for most refrigeration applications but are in the range which may satisfy air conditioning, cooling, or chilling requirements. Also, these systems are used in some chemical industries for several processes, e.g. the removal of paraffin wax from lubricating oils. Note that steam jet refrigeration systems are not used when temperatures below 5°C are required. The main advantages of this system are the utilization of mostly low-grade energy

    The refrigeration system can be defined as a closed system in which the process of absorbing and rejecting heat is performed by flowing a refrigerant in a vapor compression cycle. In its simplest form, the refrigeration system consists of five components: the compressor, condenser, evaporator, expansion device, and interconnecting piping.…

    This experiment is conducted by placing 2mL of Turpentine and 15mL of water into the flask.10mL graduated cylinder is used as the receiver.All the connections are make sure tighten.Next,two boiling chips are added to ensure smooth bubbling and prevent bumping of the liquid up into the distillation head.The heating mantle is adjusted to give vigorous boiling.The first 1.5mL of distillate is discarded and the next 5mL is collected.The volumes of the water and turpentine layers in this distillate are recorded.The recorded volume is then compared with the ideal steam distillation law using the tabulated vapour pressure and densities.…

    Mechanical refrigeration is done by three processes that are circulation, evaporation, and condensing a fixed supply of refrigerant in a closed system. Evaporation takes place at a low temperature and low pressure while condensation occurs at a high temperature and high pressure. Thus, it is possible to transfer heat from an area of low temperature (i.e., water storage tank) to an area of high temperature (i.e., environment).…

    In industry, a heat exchanger is used to cool down streams for temperature sensitive processes. The now hot cooling water is useless to the plant unless something is done to cool it down. In industry, cooling water towers are used to bring the water back down to a sufficient level . In a cooling tower, outside atmospheric air is flowed through a “column” while the hot water sprayed into the system. Since air is never at full saturation of water (unless it is raining), some of the hot water will evaporate to satisfy equilibrium. When this water evaporates, heat is taken from the surrounding liquid water which cools it down. In cooling tower design, a very important variable is the wet bulb temperature of the air. The wet bulb corresponds to the current humidity of the air. The greater the difference between the air temperature and wet bulb temperature, the greater the humidity.…

    Abstract- According to a cautious estimate, approximately 10% of the energy available at the crankshaft in a diesel operated vehicle is used for operating the compressor of the vehicle’s air-conditioning system. This is a huge loss if one takes into account the fact that the thermal efficiencies of most diesel operated vehicles range from 2030% when in pristine condition. The bottom line is that a great deal of diesel is consumed to generate electricity. In addition to this, alternating current via an alternator is necessary for the operation of the conventional a/c system. The refrigerant, usually R12 or R22 leaks easily. Being a secondary refrigerant, it is also harmful to the environment. Conventional air conditioning systems are also questioned due to the ODP (ozone depletion potential) and GWP (global warming potential) caused by the CFCs or HCFCs. Increasing recognition of environmental problems associated with CFCs and HCFCs has opened favourable opportunities for the development of green air conditioning technologies. This project report presents a revolutionary silica gel – water adsorption system for air conditioning in automobiles. The cooling effect is achieved by recovering waste thermal energy from the exhaust gases. The system is cheap and easy to fabricate. The refrigerant, being water, is environment friendly. The report provides the details regarding the construction of a prototype fabricated on this technology, by the co-authors. The design of the generator, which is the focal part of the system, is novel yet simple. The experimental results obtained, while conducting tests on a four stroke diesel engine from Mahindra have been included.…
