REFRIGERATION TEST RIG
Model Number : NAERF-01E
The REFRIGERATION test rig works on simple vapor compression refrigeration cycle and uses R‑134a as a refrigerant. It is environment friendly refrigerant gas available in the market. The system is fabricated such that students can observe and study vapor compression cycle, its component principle & working. The arrangement of parts is such that, all the parts are visible, within reach and working can be easily understood
List of Experiments :
- To study various components and controls used in vapor compression cycle.
- To evaluate actual & theoretical C.O.P. of vapor compression cycle.
- To plot actual refrigeration cycle on P‑H chart.
