please provide me the ppt of ejector expansion refrigeration cycle,,,because i needed this ppt for my mini project...
so kindly help me[/size][/font]

dear sir/medem my name is Thozamile from welkom,i would like to register for,2015,at lilitha college of nursing,at mthatha, my adress,is 126 pollokong village,welkom 9459.

To get full information or details of ejector refrigeration cycle please have a look on the pages

if you again feel trouble on ejector refrigeration cycle please reply in that page and ask specific fields in ejector refrigeration cycle

EJECTOR refrigeration cycle of expansion (EERC)


SUMMARY
Expansion cycle ejector refrigeration (EERC) is a variant of the standard vapour compression cycle in what year the ejector is used to restore part of the work that would otherwise be lost in the expansion valve. In initial Testing consortium of poor performance, mainly due to the non-equilibrium thermodynamic conditions causes the ejector nozzle. The changes made to fix the problem and improve the performance of significant were found.
Ejector refrigeration cycle System brand of DENSO world first ejector cycle technology, which won the prize for climate protection, the environmental protection agency for 2006 year. This new technology will reduce energy consumption and greenhouse gas emissions, vehicle air conditioning, refrigeration and heat pump housing.
When this technology is installed in the refrigerating unit and combined with other additional breakthroughs in components and controls, it improves the efficiency by more than 50%, leading to a reduction of 70% of emissions of refrigerants and a 60% reduction in carbon dioxide emissions.

cooling
Cooling process of removing heat from an enclosed space in a year, or substances, and rejecting the goal of lowering the temperature elsewhere confined space or substance, and then claiming that a lower temperature.
2.1 the cooling Unit
Commercial refrigerators in the United States partly by rating in tons. Much less common definition: 1 tonne of refrigeration is the rate of heat removal required to freeze a metric ton (i.e., 1000 kg) of water at 0° c for 12:0 am.
1 refrigeration ton = 13898 kJ/h = 3.861 kW
2.2 cooling methods
• Necikličeskie refrigeration

Vapor-Compression refrigeration Cycle 2.41
Para-compression refrigeration cycle consists of four components: evaporator, compressor, condenser and expansion (or choke) the valve. the most widely used refrigerant cycle is steam-compression refrigeration cycle. The perfect pair-compression refrigerating cycle, the refrigerant enters the compressor as a slightly overheated steam at low pressure. This goes from the compressor and then enters the condenser, vapour pressure at elevated some where the refrigerant is condensed as heat is transferred to cooling water or the environment. the refrigerant leaves the condenser, as then the liquid under high pressure. Pressure of the fluid as it flows from the fall through the expansion valve, and as a result, some of the liquid cold flashes into steam. The remaining liquid, now at low pressure and temperature, evaporate in the evaporator in the form of heat from the cooled space transmitted. It is then the ship back into the compressor.
