Industrial Refrigeration:Potential for Energy Conservation.

摘要

This report uses background theoretical and empirical information to identify the following major sources of inefficiency in industrial vapor compression refrigeration systems:temperature difference between the evaporator and condenser;waste heat lost via the condenser; nonideality of refrigerants;operation of system at lower than design peak load;inefficient heat transfer across heat exchanger walls;compressor inefficiency;irreversible expansion of refrigerant through the throttling valve;and superheating and supercooling in the evaporator and condenser,respectively.
