Agent, completes cycle of operation using it to the Absorption of refrigerant vapour.Absorption Refrigerator is mainly by several heat exchangers
Composition.Conventional Absorption Refrigerator has ammonia water absorbing refrigerator and two kinds of lithium-bromide absorption-type refrigerating machine.Absorption refrigeration
The heat energy of machine both can be high-grade heat energy, such as high temperature and high pressure steam or hot water, fuel oil or combustion gas；Can also be low-grade
Heat energy, such as used heat, waste heat, solar energy or underground heat etc., and Absorption Refrigerator can be with water, ammonia etc. as cold-producing medium, therefore
There is clean environment firendly, economizing on energy and electricity, elimination electric power peak-valley difference, applied range, simple to operate, operation part is few, operating cost
Low advantage.
Certain flue gas can be produced during the work such as natural gas boiler, gas turbine, in flue gas, contain substantial amounts of heat, these
Heat can use as the thermal source of Absorption Refrigerator.But, the heat absorption efficiency of existing Absorption Refrigerator is not high, its reason
It is that natural gas flow of flue gas speed is fast, the time of staying is short in the absorber of refrigeration machine, absorbent heat absorption is limited, and passes through portion
Departure section too reduces flue gas and stops in absorber, gas fired-boiler etc. can be led to produce larger back pressure, lead to flue gas to be difficult to
Discharge in time, the flameholding on boiler and adequacy produce impact.
