An ideal multi pressure refrigeration system consists of 57 tons HP Evaporator at 9°C and 63 tons LP Evaporator at -26°C. The system uses 2-stage compression with intercooler with flash tank for the purpose of minimum works on compressors. A pressure reducer valve is installed after the HP Evaporator to equalize its pressure to that of intercooler. The condenser pressure is 40°C. The refrigerant is R22
