SR2013 Refrigeration System with Two Stage Compression Educational Equipment Air Conditioner Training Equipment

Learning Objectives / Experiments

– design and function of a refrigeration system with

two-stage compression and injection intercooling

– effect of the inlet temperature at the HP compressor on the efficiency of the compression

* with intercooling

* without intercooling

– effect of the additional refrigerant intercooling

– distribution of the compressor pressure ratios

– represent and understand the refrigeration cycle process in the log p-h diagram

Specification

[1] refrigeration system with two-stage compression

[2] hermetic low and high pressure compressors

[3] adjustable intercooling via refrigerant injection

[4] heat exchange for additional supercooling of the liquid refrigerant

[5] closed refrigeration chamber contains evaporator with fan and adjustable electric heater as cooling load

[6] digital display for temperatures, drive power of the compressors and cooling load power

[7] software for data acquisition with USB under Windows Vista or Windows 7 with online display of the log p-h diagram

[8] refrigerant R404a, CFC-free
