The "HANSA" cascade Refrigeration systems with two-stage compression are used for the generation of particularly low temperatures. At very low temperatures large pressure differences are required between the evaporator and condenser. In a compressor the volumetric efficiency drops significantly at high-pressure ratios.Therefore, two compressors are connected in series, with each compressor only having a relatively low-pressure ratio. This makes a more favorable dimensioning of the low-pressure stage compressor possible. Due to the large specific volume it requires a larger capacity at lower drive power.In addition, intercooling between the low-pressure compressor (LP) and the high-pressure compressor (HP) reduces the outlet temperature of the HP compressor to harmless values and improves the efficiency of the compression.All relevant measured values are recorded by sensors and displayed. The simultaneous transmission of the measurements to the software enables analysis and the representation of the process in the log p-h diagram in real time. Additionally, two flow meters indicate the total volumetric flow rate and the volumetric flow rate in the intercooling.Computerized Cascade Refrigeration TrainerFEATURESDesign and function of a refrigeration system with two-stage compression and injection intercoolingEffect of the inlet temperature at the HP compressor on the efficiency of the compressionWith intercoolingWithout intercoolingEffect of the additional refrigerant intercoolingDistribution of the compressor pressure ratiosRepresent and understand the refrigeration cycle process in the log p-h diagram SPECIFICATIONLow-pressure compressor (LP)Displaced volume: 25,93cm3Power consumption: 550WRefrigeration capacity: 1744W at -10/32?CHigh pressure compressor (HP)Displaced volume: 8,86cm3Power consumption: approx. 275WRefrigeration capacity: 583W at -10/32?CRefrigerantFilling volume: 1,29kgCO2-equivalent: 1,8tMeasuring rangesflow rate: 2?29L/h, 4?40L/hPressure: 1x -1?15bar, 2x -1?24barTemperature: 8x -75?125?CPower:0?562W (heater)0?750W (LP compressor)0?2250W (HP compressor)Required for operation230V, 50Hz, 1 phase230V, 60Hz, 1 phase DIMENSIONS AND WEIGHTL x W x H (approx.): 2000 x 800 x 1600 mmWeight (approx.): 265 kg
