Abstract
A lithium bromide absorption type refrigerator with a feeder for feeding interface activator in gas state is disclosed. A method for feeding said interface activator includes such steps as loading the activator into said feeder, heating for evaporating the activator, and feeding the vapor of activator into refrigerating system to intensify the absorption function.
Description
Technical field
The invention belongs to the Refrigeration ﹠ Air-Conditioning technical field.
Background technology
In history, since lithium bromide water solution when seething with excitement, can numerous air-bubble take place and make very unstability of solution surface in the generator of Absorption Refrigerator.For suppressing the generation of bubble, people attempt to use interfacial agent to reduce the surface tension of solution.And in experimentation, what the inhibition effect of bubble was more noticeable in the comparison generator is, because the adding of interfacial agent makes that absorber performance is improved greatly.So interfacial agent is used as sorbefacient and begins to be used.Like this, though actual set has been brought into use interfacial agent very early, people were almost completely unclear to the sorbefacient mechanism of interfacial agent at that time.Traditionally, people strengthen STUDY ON TRANSDERMAL ABSORPTION to interfacial agent, normally interfacial agent are mixed with lithium-bromide solution in advance, and then check its effect that strengthen to absorb, analyze its mechanism of action.Up to the present, explain, also do not obtain a generally acknowledged mechanism interpretation though there is the people to propose some.And the present invention proposes to add interfacial agent with the gas phase form, and interfacial agent is strengthened absorption mechanism research provides new method.
Summary of the invention
Purpose of the present invention is exactly at the method that people adopt liquid phase to add interfacial agent to be strengthened the situation that STUDY ON TRANSDERMAL ABSORPTION does not draw generally acknowledged mechanism interpretation, proposes the method that a kind of new research circle's surface-active agent is strengthened absorption mechanism.
Technical solution of the present invention is, a kind of lithium-bromide absorption-type refrigerating machine is made of absorber 1, evaporimeter 2, condenser 3, generator 4, interfacial agent gas phase adding set 5, tube connector 6, refrigerant vapor pipe 7, refrigerant tube 8, refrigerant vapor pipe 9, concentrated solution pipe 10 and weak solution pipe 11; Generator 4 links to each other by refrigerant vapor pipe 9 with condenser 3; Condenser 3 is being communicated with evaporimeter 2 by refrigerant tube 8; Evaporimeter 2 usefulness refrigerant vapor pipes 7 link to each other with absorber 1; Having two-way to be connected between absorber 1 and the generator 4, is respectively concentrated solution pipe 10 and weak solution pipe 11; Be connected by tube connector 6 between interfacial agent gas phase adding set 5 and the absorber 1, the interfacial agent steam is provided in absorber.
Use a kind of gas phase addition method of interfacial agent of lithium-bromide absorption-type refrigerating machine, lithium bromide water solution is heated in the generator 4, the steam that produces enters condenser 3 and is cooled, the water as refrigerant that is cooled enters sweat cooling in the evaporimeter 2, become steam and enter absorber 1, the bromize lithium concentrated solution that is come from generator 4 in absorber 1 absorbs, and the weak solution of formation is introduced heating evaporation in the generator 4 again.
When refrigeration system was moved, the activating agent of 50-400ppm was heated evaporation in the interfacial agent gas phase adding set 5, and the activating agent steam of generation enters in the absorber 1, strengthened the absorption of bromize lithium concentrated solution for the water as refrigerant steam that comes flash-pot 2.
Used activating agent is isooctanol 2-Ethyl-1-Hexanol, octanol 1-octanol, enanthol 1-Heptanol or hexanol 1-Hexanol.
The invention has the beneficial effects as follows, add interfacial agent with the gas phase form, directly act on sorbent surface, the effect that absorbs is strengthened in performance, for the absorption mechanism of research circle's surface-active agent provides new method.
