Section, plays an important role to the strategy of energy-saving and emission-reduction.
Industrial refrigeration is compression refrigeration and absorbed refrigeration using more, and compression refrigeration advantage is high cooling efficiency, hence it is evident that
Disadvantage is exactly power consumption；It absorbs refrigeration and mostly uses lithium bromide absorbing type refrigeration, unit advantage: using thermal energy as power, power consumption is few.
Disadvantage: service life is shorter than compression；It economizes on electricity not energy-efficient, steam consumption is big, and the thermal efficiency is low；Unit is run under vacuum for a long time, outside
Gas is easy intrusion, if air invades, causes cooling metering, therefore requires stringent sealing, increases manufacture and operation difficulty；Unit heat extraction
Duty ratio compression refrigeration is big, more demanding to cooling water quality；Lithium-bromide solution has strong corrosivity to carbon steel, influences machine
Group service life and performance；Cryogenic temperature only limits zero degree or more；Ammonia absorption refrigeration, cryogenic temperature can be lower than zero degree, but water is not achieved
Completely isolated from ammonia, distillation process increases cost of investment and operation difficulty, reduces heat utilization rate, improves energy
Consumption.
