Description

509774 V. Description of the invention 0) ^ ^ Ming refers to an absorber with an absorption and diffusion type freezing structure, not to mention: a large volume and a length-reduced cooling unit, and a receiver installation structure. It is known that the device of the refrigerating cycle system of the air-conditioner is mainly composed of a living unit 1: a chlorine gas cabinet 2, a separator 3, and a liquid heat exchanger 4 and a 5 "/ kindizer 7, an evaporator 8, an air heat exchanger q, Gold tube 1 is divided into Γ1 " type tube ", fan 13, asbestos board / 4, which uses ammonia water (amm 〇niaaq S〇l 4 U 6 〇USU ti 〇) has the advantage of high latent heat of vaporization as: water Yuhang > can absorb a large amount of ammonia gas under visible and normal pressure. The characteristics of ammonia gas absorbed by heating in the reverse direction ▲ and 祜 will escape as a result of heating: U Evaporation rate and pressure level of the system 丨 =… 2. The pumping operation of the date shrinking machine has no compressor operation sound. Mechanically, as shown in the first figure, the generator 1 is connected to the thunderbolt by a titanium heat pipe * to the acoustic generator 1, so that the ammonia gas escapes the solution, and It is said that the amount of heat generated is increased, and some dissolved vapors follow a separate pipeline 3a, ^ h are internal and internal, and after this, the tube 3b flows into the liquid heat. The exchanger 4, when it arrives, will come, the body will be turned from the gas part in 3 by the central air pipe 3 a by gravity: 5: in the separator, the gas Lighter, still going up to the dewaterer :: turn 2 analyzer 1 1 or the crossbow liquid will flow down and return to the analyzer ii AY There is any water dewaterer Θ There is a circle of resistance plates 6 on the drain pipe 6 1 Inside the generator 1, the coin liquid rises. Therefore, it can stop the gas on page 4. 509774 V. Description of the invention (2) After passing through the water separator 6, the pure ammonia gas will enter the condenser 7, and the condenser 7 is divided into a condensation tube 7a and a condensation There are two parts of tube 7 b, and the condensation tube 7 a has fins for cooling to condense a part of the vapor. The heat in the system is only used for the ascent cycle, and until the point of condensation tube 7 a, the subsequent circulation depends on gravity only. Then, the pure ammonia flows to the evaporator 8. In addition, part of the uncondensed vapor in the condensing pipe 7 a rises to the condensing pipe 7 b and recondenses. The U-shaped tube 1 between the condenser 7 and the evaporator 8 As a reservoir of liquid ammonia, the ammonia liquid storage volume exceeds a predetermined level, that is, it flows into the evaporator 8, and due to the effect of gravity, the liquid tends to be horizontally balanced. After the U-shaped tube 12 is filled with liquid, it will flow into the evaporator 8. When the ammonia liquid enters the evaporator 8 along a series of horizontal baffles 8a, a thin layer of ammonia liquid film is formed. Hydrogen is in the U-shaped tube 1 2 The charging at the place allows the liquid ammonia to be depressurized to the design standard, and can be evaporated at a low temperature in the evaporator 8. When it is evaporated, it absorbs heat and achieves the condensation effect. It is discharged by the fan 13 and isolated by the asbestos board 14. The more hydrogen, the less the ammonia content, the lower its temperature. When ammonia is mixed with hydrogen, the mixed gas is heavier than hydrogen, that is, it is dropped into the absorber 5 along the inner tube 9a of the gas heat exchanger 9, At the same time, the upstream hydrogen of the outer tube 9 b is cooled, and the weak ammonia solution flowing from the separator 3 through the liquid heat exchanger 4 to the top of the absorber 5 is absorbed by the ammonia when it comes into contact with the mixed gas from the gas heat exchanger 9. Only hydrogen is left. Hydrogen is insoluble in water and is relatively light. Therefore, it rises along the outer tube 9 b of the gas heat exchanger 9 and returns to the evaporator 8, and then mixes with ammonia vapor. The fins 5 a outside the absorber 5 are Air cooling, which can cool the weak ammonia solution and enhance its absorption capacity. At the same time, it also emits heat during absorption.

V. Description of the invention (3) j = air-cooled fin 5 a removes this heat and promotes the continuous circulation of the system. Second, after the liquid absorbs ten amounts of ammonia vapor, it becomes a strong solution sinking into the absorber 5, and Continue downward through the liquid heat exchange gas 4 and the analyzer 1 1 and return to the generator 1 to start another cycle. The disadvantage of Yongzhizhi is that the absorber is provided with a relatively long coiled pipe, which increases the volume of the machine and the whole. Therefore, the volume of the known is quite large, and it is more in line with actual needs. The inventor It is to conduct research and development to solve the problem that the government knows that it is too long to reduce the overall volume. ^ The purpose of this month is to provide an absorption ram with an absorption diffusion cold structure. The purpose is to make the structure of the absorber simple. The absorber is always in a tubular shape, but there are spiral devices to make the overall processing easy. Delay &: The time when the liquid machine passes through the absorber, the extended dilute solution reacts in the absorber, and the flow path of the mixed gas flowing into the ammonia gas and hydrogen gas is shorter, but it comes into contact with the dilute ammonia water on the inner wall of the official, resulting in better Reaction effect, "" lower the weight of the system, reduce the volume; so the invention can produce

The body t,: t 5: ’frozen structure with better overall operability than the conventional one, so that the S-type frozen structure is no longer a dream. ★ The structure of the present invention. The freezing cycle is composed of a generator, a rectifier, an evaporator, an agricultural solution tank, and an absorber. When the ammonia solution is heated, it flows to the condenser tube and flows to the condenser tube. The road is led by / chen, he, dingyue / melon pipe into the evaporator pipe, absorption = 'then it is connected with ammonia tank through ammonia solution, sucks upright, and receives lice gas and hydrogen When passing through the absorber, the concentrated ammonia gas is dilute = government, and the device reacts into a concentrated solution of ammonia water to return to the concentrated solution = two of two = the liquid is in a spiral, night tank, dilute ammonia and hydrogen 509774. V. Description of the invention ( 4) Pass the air pipe to the hydrogen pipe, and the hydrogen pipe also leads into one end of the evaporator's pipe, and simultaneously releases ammonia and hydrogen at the closed end of the other end of the evaporator's pipe. Exchange reaction, absorb heat and refrigerate, release coldness, and return the generated ammonia vapor together with hydrogen and discharge it into the concentrated solution tank through the introduction tube. In order to allow your reviewers to further understand the technology, means and effects adopted by the present invention to achieve the intended purpose, a better and feasible embodiment will be given in conjunction with the drawings to explain in detail later. I believe that the purpose, characteristics and The advantages should be a deep and specific understanding.

Tubular, water vapour to water vapour 0, part 1 is returned to the condenser 5 0 condenser second and second pipeline 5, the two pipelines are arranged in a bend 6 and the dilute mixed flow rectifier in the 7th condensation 5 It consists of 3 7 vertical liquid pipe 3 enlarged tube solution return pipe 3 water 7 4 return pipe water 7 4 Because of this 7 3 and 7 3 or ammonia dilute solution, the condensing pipe 5 5 is divided into 5 2. The pipe occupies one The pipeline becomes ammonia solution and ammonia contains 5 1 in the tube. The concentrated solution wave tube returns straight down to 7 reflux or the end of the tube flow tube 3 8 8 is cooled by gravity at the end of 3 8 °. In the steam ammonia 7 2 7 2 also cold pipe 37. Device 5 0 with 5, and there are a number of 5 5 rooms with space 5 2 again

509774 V. Description of the invention (6) Because the condenser pipe 5 2, 5 5 is inclined and has a reverse folding shape, the ammonia liquid 7 6 will flow to the end of the condenser second pipe 5 5 At this time, a first ammonia liquid pipe 57 is connected to the end of the second pipe 55 of the condenser, and a few third fins 5 8 are still provided in front of the first ammonia liquid pipe 57 to enhance cooling. The liquid pipe 57 is guided through a second ammonia liquid pipe 59 into the pipe 62 of the evaporator 60.

The first ammonia liquid pipe 57 is passed through a receiving block 61, and the second ammonia liquid pipe 59 is contained in the pipeline 62. In fact, the first ammonia liquid pipe 57 and the second ammonia liquid pipe 59 are Same pipeline. In addition, the pipes of the dilute solution pipe 37 and the rectifier 51 are the same as those of the condenser first pipe 5 2 and the condenser second pipe 55, both of which are designed to facilitate production. The focus of the present invention is on the structure in the absorber. One end of the absorber pipe 4 1 of the absorber 40 is connected to the concentrated solution tank 31, and the dilute solution 7 4 in the absorber 40 is refluxed. There are several absorber fins 4 2 on the outside, and a spiral device 4 3 on the inner wall of the absorber pipe 4 1 so that the dilute solution 7 4 surrounds the inner peripheral wall of the absorber pipe 4 1 and the concentrated solution tank On the inner liquid surface, there is a hydrogen-ammonia mixed gas formed by the hydrogen 7 7 and ammonia vapor 7 9 flowing in from the evaporator 60, and the mixed gas is released from the liquid surface passing through the solution (concentrated ammonia water 7 1). The concentrated ammonia gas 7 5 absorbs the concentrated ammonia gas 7 5 for the first time, and then introduces the mixed gas into the absorber 40 to perform the second absorption reaction. The concentrated ammonia gas 7 5 enters the absorber 40. After reacting with the dilute solution 7 4 to form a concentrated solution 7 1, the solution is refluxed to the concentrated solution tank 31 along the spiral device 4 3. In addition, the spiral device provided in the inner tube wall of the absorber 40 pipeline 41

Page 9 V. Description of the invention (7) 4 3, the spiral device 43 is made of spiral impeller snail fibers, the inner wall is made of Shi Zhongxi, and the lanes are further cooled. Efficacy = The shape of the ammonia water level or the spiral groove of the semi-circular μ 'spring in the second section can be a μ-shaped, 5 3 can be a capillary, ^, type or square. The spiral beam is placed with fiber bundles or foamed metal; the thin structure is a woven mesh or a sintered fan of the three pigeons.

As shown in the fifth figure above, the dilute solution directly flows down like a rotary device, and at the same time, it can prevent the flow resistance of the return pipe 38 from being too large, and block the outlet 38. In addition, the ν-shaped notch 3 8 2 can also be an oblique cut to facilitate the outflow of the solution and prevent clogging. % In addition, the absorber 4 〇 near the other end of the pipeline 4 1 to form a compression zone 4 4 'The compression zone 4 4 is located above the absorber pipeline 41 and the dilute solution pipe 38, using gravity to suppress the concentrated ammonia gas 7 5, and then the absorber pipe 4 1 is connected with an absorber guide block 4 5 at the other end, and the absorber guide block 4 5 is connected with an air duct 46, and a number of cooling fins 47 are provided outside the air duct 46 to further prevent non-absorption. Completely concentrated ammonia gas is cooled to ammonia liquid 7 6. Because the air duct 46 is arranged in a downwardly bent manner, after the concentrated ammonia gas 7 5 and hydrogen 7 7 pass through the absorber 40, part of the concentrated ammonia gas 7 5 and the dilute ammonia water 7 7 are diluted in the solution. 7 4 The absorber 40 reacts with the concentrated ammonia water 1 which becomes a concentrated solution to reflux, so that the amount of ammonia gas in the mixed gas is reduced again, and dilute ammonia gas is generated.

Page 10 3uy / 74, description of the invention (8) The mixed gas of 8 and chlorine 7 7 flows through the air duct 4 6, because most of the air duct 4 ^ is pure hydrogen 7 7 and air duct 4 6 Connect a hydrogen I4 9 'set the hydrogen tube 49 upward and guide the hydrogen 77 to move upwards' according to the characteristics of the hydrogen 7 7, that is, the lighter the gas will flow upward.

A drainage tube capillary ^ weaving 4 8 1 ′ can be provided in the ammonia liquid drainage tube 4 8 to prevent The tube diameter is too small to produce a liquid seal. The other end of the ammonia liquid drainage tube f 4 8 is connected to the concentrated solution tank 3 1 under the liquid surface. The hydrogen tube 4 9 also passes through a receiving block 61 and is guided into the evaporator. The pipeline 6 of 60, the inner pipeline 3 of the evaporator 60, the hydrogen pipeline 4 9 and the ammonia pipe 59 are arranged side by side at the same time, and the pipeline 62 of the evaporator 60 can be a bent one. The pair of hydrogen pipes 49 and the second ammonia liquid pipe 59 to the pipeline 6 2 form another outlets at the same time, and simultaneously release the ammonia liquid 7 6 and the hydrogen gas 7 7 to allow the ammonia liquid to lice milk 7 7 for heat exchange. The evaporation reaction can absorb heat and cause the mixture of ammonia vapor 7 9 and hydrogen 7 7 to return after evaporation, and return along the internal space of the pipeline 6 2 from the other end to the end near the pipeline 6 and the pipeline 6 2 An introduction tube 6 4 is connected, so that ammonia vapor 7 9 = cyano oxygen 7 5 and hydrogen 7 7 are discharged into the concentrated solution tank 31 through the introduction tube 6 4. In the mountain t, the other end of the evaporator 60 is not higher than the end of the second pipe 5 5 / to form a U-shaped communication pipe, the ammonia liquid 7 6 will naturally move by gravity to reach the pipe The other end of 6 2 flows out, because here, the exchange speed is fast, for the convenience of the ammonia liquid outflow. Therefore, the evaporation state 60 of the present invention can achieve a rapid heat exchange function under the forward flow. , ^
