Engineering Labs Equipment is a leading Computerized Cascade Refrigeration Trainer Manufacturer,and suppliers in India
The 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.
All relevant measured values are recorded by sensors and displayed.
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.
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.
