Project Title : Design & Development of Single Stage Vapour Compression Refrigeration Test Rig

Abstract :

Vapour compression refrigeration system (VCRS) is used in a small scale to high scale refrigeration system. The VCR system is work on Vapour Compression Cycle (VCC) principle. In this paper we differentiate the VCC in simple and adding Liquid Suction Heat Exchanger (LSHX). By adding heat exchanger in liquid side the temperature of liquid line is higher than the that of the suction line, heat flows the from liquid to suction line and therefore the temperature of exit of condenser is decreases and increase in the suction temperature (superheating). The use of LSHX is always followed by superheating on the suction of the compressor. The superheating causes an increase in the input power. As a result, the use of LSHX is expected to enhance the COP of the system. There are three parameters, viz., the cooling capacity, the discharge temperature and COP investigated in theoretically.

Working Model:

RESULTS :

The refrigerating effect (h₁ – h₅) of the vapour compression cycle after undercooling is higher than the refrigerating effect (h₁ – h₄) without undercooling but the compressor work becomes (h₂ – h₁), these results enhance the COP of the vapour compression cycle directly and fulfill the our requirement.

Role: Leading the team, Design & Developing the components as well as software working work.
