OPTIMIZATION OF LARGE HEAT PUMPS IN INDUSTRIAL PLANT.

Author(s) : SCHNITZER H.

Summary

THE UTILIZATION OF HEAT PUMPS IS OFTEN LIMITED BY THEIR INABILITY TO GENERATE SUFFICIENT LOW PRESSURE STEAM AT 383-433 K (110-160 DEG C), THE MOST USUAL INDUSTRIAL REQUIREMENT. IN SOME COUNTRIES ELECTRICALLY DRIVEN HEAT PUMPS ARE COSTLY, AND GAS OR DIESEL UNITS ARE EQUALLY EXPENSIVE. THE ECONOMY OF ABSORPTION HEAT PUMPS IS ALSO LOW BECAUSE THEIR RELATIVELY LOW COP AND IT IS IMPOSSIBLE TO GENERATE STEAM. IF HOWEVER THEY ARE DRIVEN BY WASTE HEAT FROM A DUAL GENERATION SYSTEM, THEN THEIR EFFICIENCY IS IMPROVED. THE AUTHOR CONSIDERS IN DETAIL DUAL SYSTEMS IN WHICH ELECTRICITY IS GENERATED FROM A BACK PRESSURE TURBINE AND PART OF THIS IS USED TO POWER A HEAT PUMP TO AUGMENT THE HEATING LOAD. G.R.S.
