REFRIGERATION TEST RIG

DESCRIPTION:
The REFRIGERATION test rig works on simple vapour compression refrigeration cycle and uses R134a as a refrigerant. It is environment friendly. The system is fabricated such that students can observe and study vapour compression cycle, its component principle & working. The arrangement of parts such that, all the parts are visible and working can be easily understood.
