Test of a reciprocating compressor for ammonia heat pumps.

Author(s) : HIVET B., ARZANO C., DUCRUET C., BRAENDGAARD T.

Summary

Ammonia and HFC-134a appear to be the only fluids useable for heat pumps on the basis of regulations and simple thermodynamic criteria. Ammonia has been revealed as being exceptionally efficient for high condensation temperatures. However, only recently has its use been possible through industrial refrigerating compressors with a design working pressure of 40 bars. Test results confirm the interesting performance of this fluid. A comparison against HFC-134a reveals that ammonia offers COPs at the same rate, or even better, and this at much greater volumetric heating capacity. Two applications in the food industry are presented.
