Abstract
The utility model relates to a pump-less lithium bromide absorption refrigerator, which aims to solve the problems of large occupation area, complex structure, large energy consumption, high cost, and existence of noise in the present lithium bromide absorption refrigerator. The utility model is characterized in that the liquid in the generator is divided into two portions by an isolating mechanism. A thermal siphon and a vapor balancing pipe pass through the vapor-liquid separator in order to maintain the pressure balance of the circulating system. The high liquid level pressure enables the automatic circulation of the refrigerant water, the concentrated solution and the dilute solution. The utility model utilizes solar refrigeration, applicable to air conditioners in families, dance halls, hotels, ships, and other places.
Description
The utility model belongs to a kind of refrigeration plant, and relating to water is cold-producing medium, and lithium-bromide solution is the pump-free lithium bromide Absorption Refrigerator of absorbent, produces the above idle call cold water of zero centigrade.
At present, the lithium-bromide absorption-type refrigerating machine of common use has patterns such as monotubular, the bitubular, three, and it is little, compact, in light weight wherein to have a volume with monotubular formula structure, advantage such as device height is low.The lithium-bromide absorption-type refrigerating machine of low capacity adopts this kind pattern more, and the xs-200 type lithium-bromide absorption-type refrigerating machine of Shanghai first Coolers Factory that announces in " the refrigeration plant handbook " published as National Defense Industry Press is the monotubular structure.Use but be generalized to family, still exist and occupy that the space is big, cost is high, energy consumption is big and noisy shortcoming.Its reason is that lithium-bromide absorption-type refrigerating machine all be unable to do without the effect of canned motor pump, and accumulating water as refrigerant in the evaporimeter water pond needs the evaporimeter canned motor pump to spray outer surface at evaporator tube bank equably; The weak solution that the concentrated solution of coming from generator enters absorber and the absorber is mixed the intermediate solution that forms, and needs the outer surface of the even spray of absorber canned motor pump at the absorber tube bundle; Need the generator canned motor pump to be sent to go heating in the generator owing to having absorbed weak solution that water vapour obtains.The existence of canned motor pump bromizates lithium Absorption Refrigerator complex structure, occupies that the space is big, cost improves, energy resource consumption is big, noise is arranged, the miniaturization difficulty.
The purpose of this utility model is in order to overcome disadvantages of background technology, to design a kind of miniaturization, simple in structure, power consumption less, low, the noiseless of the cost pump-free lithium bromide Absorption Refrigerator of circulation automatically.
The utility model removes three canned motor pumps that are used to circulate in the existing lithium-bromide absorption-type refrigerating machine to achieve these goals.As if this imagination is unworkable theoretically, also is that people want to solve and unsolved problem for a long time.Because whole circulation system is to get back to the generator of high pressure again to evaporimeter and absorber low pressure from generator and high condenser pressure, the spray of water as refrigerant wherein, the conveying of the spray of intermediate solution and final weak solution all needs power to circulate, especially the weak solution of low pressure is sent in the generator of high pressure, not having canned motor pump is the obstacle that can't cross.How to realize continuous kind of refrigeration cycle: utilize the boiling of heated lithium-bromide solution to produce steam bubble, the steam bubble come-up of being heated drives concentrated solution and rises to vapour liquid separator along thermal siphon, its objective is the concentrated solution circulation that begins lithium bromide with lower pressure.Water as refrigerant in the evaporimeter water pond utilizes high-order pressure that water is sprayed on the evaporimeter; High-order concentrated solution is utilized high-order pressure through over-heat-exchanger, with this solution spraying to absorber.The pressure of a rare lithium-bromide solution utilization high position and get back to the generator of high pressure has been finished the circulation of refrigeration.The key of cyclic process is how to control the pressure of boiling lithium-bromide solution.Hypertonia, rare lithium-bromide solution can not be got back in the generator of high pressure; The dense lithium-bromide solution of hypotony can not rise to vapour liquid separator.All can not finish circulation.
The utility model will be set about from the pressure of the balance circulatory system, and balance fluid pressure and balance gas pressure reach the vapour-liquid pressure balance.The balance fluid pressure: adopting dividing plate that liquid is divided into boiling liquid and balance liquid two parts, is not only separately but also two parts liquid of UNICOM, and the liquid dividing plate under impels concentrated solution to rise to vapour liquid separator owing to be heated continuously, has begun the first step that circulates.If surpass cyclic balance pressure, by balance pipe boiling liquid pressure is sent to balance liquid, reach the balance fluid pressure; Balance liquid top gas is compressed with boiling liquid and produces steam formation gas hypertonia, adopt the gas balance pipe to be communicated with generator and vapour liquid separator, make generator liquid and vapour liquid separator space keep the gas pressure balance, therefore the vapour-liquid two-phase circulatory system reaches new balance, guarantees that the circulatory system continues operation.Also must solve liquid when solving vapour-liquid circulatory system equalizing pressure circulates automatically, on the structure of circulating system, make water as refrigerant, concentrated solution and weak solution liquid level are higher than corresponding evaporimeter, the position of absorber and generator utilizes liquid level pressure to finish circulation automatically.
The utility model is by generator (1-8,21,22) condenser (15) evaporimeter (16) absorber (18) heat exchanger (19) and vapour liquid separator (12) are formed, be characterized in the interior dress of cylindrical shell (2) heat exchanger tube (3) of generator, heat exchanger tube (3) top welding interrupter: upper folding surface (4) and lower folding surface (5) are engaged with each other and separately constitute fluid balance groove (21), the thermal siphon (7) of many break-through of upper folding surface (4) welding, and pass the upper cover (6) of cylindrical shell (2), upper cover (6) is gone up the gas balance pipe (8) of welding break-through, and the bottom surface (11) of people's vapour liquid separator (12) is worn in thermal siphon (7) and gas balance pipe (8) upper end; In vertical vessel (14), set gradually condenser (15) from top to bottom, evaporimeter (16), absorber (18), in vertical vessel (14) lower side and cylindrical shell (2) top heat exchanger (19) is set, the woven hose of heat exchanger (22) is welded to connect with generator cylindrical shell (2) underfeed mouth (23), and other parts connect with pipeline valve.
Another characteristics of the present utility model are division board mechanisms: under division board (24), and the fluid connection pipe (25) of two symmetries of welding break-through.
