The present invention relates to an absorption type air conditioner, in particular an external cylinder that acts as an evaporator and an absorber during the cooling operation, an external cylinder for pre-cooling of the solution and an internal cylinder of the condenser, integrally and directly installed in the absorption type air conditioner It is about.

As a conventional absorption type air conditioner employing such a method, there is one configured as shown in FIG. 1, filed by the applicant of the present invention on November 3, 1992 (Application No. 92-20548).

In the conventional absorption type air conditioner shown in FIG. 1, the high temperature and high pressure refrigerant vapor generated by the generator 1 during the cooling operation is performed by an external cylinder 5 acting as an evaporator and an absorber and an internal cylinder 4 acting as a condenser. It flows into the inner cylinder (4) via the steam transfer pipe (3) formed around the heat transfer fins (17) disposed in between, and the two-way solenoid valve (28) disposed in the middle of the steam transfer pipe (3). At this time, the flow path of the refrigerant vapor from the generator 1 to the feeder pipe 26 is blocked by the three-way solenoid valve 27, and the lower portion of the inner cylinder 4 from the lower portion of the inner cylinder 4 to the upper space chamber 10 of the outer cylinder 4 is blocked. Since the flow path is open, the refrigerant vapor introduced into the inner cylinder 4 is condensed while emitting condensation heat from the inner and outer wall surfaces 4b and 4a of the inner cylinder 4, and the inner cylinder 4 to which the heat transfer fins 17 are attached. To the upper space chamber 10 of the outer cylinder 5 through the first connecting pipe 11 connected to the lower part of the first connecting pipe 11 and the three-way solenoid valve 27 disposed in the middle of the first connecting pipe 11. Inflow. The coolant introduced into the upper space chamber 10 of the outer cylinder 5 falls through the plurality of through holes 9a formed in the separator plate 9 and contacts the outer wall of the cold water pipe 7 while the cold water pipe 7 The evaporation heat is taken from the cold water pipe (7) and is discharged from the generator (1) and discharged from the generator (1) through the solution heat exchanger (6). It is absorbed while giving heat of absorption to the concentrated solution flowing along the inner wall 5b, which becomes a rare solution. This rare solution is discharged through the second connecting pipe 13 connected to the lower space chamber 18 of the outer cylinder 5, and exchanges heat with the agricultural solution while passing through the solution heat exchanger 6. It enters 1) and forms a cooling cycle.

At this time, the cold water in the cold water pipe (7) cooled by the evaporation action of the refrigerant from the surface of the cold water pipe (7) passing through the lower space chamber 18 is introduced into the indoor heat exchanger (not shown) through the discharge pipe (75). The room is cooled down.

In addition, the cooling fan (8) installed in the upper part of the system around the heat transfer fin (17) disposed between the outer cylinder (5) and the inner cylinder (4) and the heat transfer fin (19) disposed in the hollow of the inner cylinder (4). Intake of air in the direction of the arrow (A) through the air inlet 29 by the driving of the exhaust cylinder in the direction of the arrow (B) of the upper part of the outer cylinder (5) acting as an absorber and heat of the condenser in the inner cylinder (4) Absorption heat from the inner walls 5b and 5c of the lower space chamber 18 is removed.

However, since the cooling effect of the heat transfer fins 17 and 19 is not good, the solution and the refrigerant temperature and the pressure inside the outer cylinder 5 and the inside of the inner cylinder 4 rise, resulting in unstable operation of the system and in the cycle. When the crystal of the solution is highly likely to precipitate, the coolant pump 21 operates by detecting the temperature of the overheat detection temperature sensor 20 installed in the inner cylinder 4 and the outer cylinder 5, respectively. The cooling water 23 collected in the (22) is sent to the sprayer 25 located above through the cooling water supply pipe 24 to spray the cooling water 23 around the heat transfer fins 17 and 19 in the sprayer 25. Remove heat of condensation and heat of absorption. The cold water introduced through the main cooling water introduction pipe 70 through the above process is cooled by evaporation of the refrigerant liquid on the surface of the cold water pipe 7 while passing through the outer cylinder 5, and then heat exchanged in the room through the discharge pipe 75. It is supplied to the machine to cool the room.

Next, during the heating operation, the spray action from the fan 8 and the atomizer 25 is stopped and the high temperature and high pressure refrigerant vapor discharged from the generator 1 is blocked by the two-way solenoid valve 28 and the three-way solenoid. The upper flow chamber 10 of the branch pipe 26 and the outer cylinder 5 at the same time as the lower flow path of the valve 27, that is, the first connecting pipe 11 'upstream of the first connecting rod 11 is blocked. The first connection pipe 11 side communicating with the unit is opened, and the high-temperature, high-pressure refrigerant vapor is introduced into the upper space chamber 10 of the outer cylinder 5. Accordingly, the high temperature and high pressure refrigerant vapor flows from the upper portion to the lower portion of the outer cylinder 5 and condenses on the surface of the tube used as the cold water tube 7 during cooling to generate heat of condensation and flows into the cold water tube 7. At the same time as the cold water is heated, the upper part of the inner wall 5c in the lower space chamber 18 of the outer cylinder 5 through the solution pump 35, the solution heat exchanger 6, and the concentrate discharge pipe 12 from the generator 1; The high temperature and high pressure agricultural liquid flowing in flows along the inner wall of the outer cylinder 5, is mixed with condensed water condensed in the lower part of the lower space chamber 18, and the generator 1 is connected to the second connecting pipe 13. The cold water flowing in the cold water pipe 7 is configured to be heated by condensation heat and supplied to a heat exchanger in a room (not shown) through the discharge pipe 75 to heat the room.

By the way, in the conventional absorption type air-conditioning device configured as described above, precise and complicated work is required in the manufacturing process of the adhesion of the fins, and if the contact of the fins is poor, there is a concern that the heat transfer efficiency is lowered due to the increase of the contact thermal resistance. Also, a connection pipe between generator and inner cylinder (condenser), inner cylinder (condenser)-(outer cylinder) evaporator, solution heat exchanger-outer cylinder (when absorbing) and sprayer-cooling water between inner cylinder and outer cylinder There is a problem in the manufacturing process and installation work, such as to be careful to configure the above-mentioned heating fin between each connecting pipe by arranging, there was a problem that raises the manufacturing cost by this difficulty.

The high temperature and high pressure concentrated solution generated in the above was supplied to the solution heat exchanger, and the concentrated solution was supplied to the upper portion of the second outer cylinder and cooled. Afterwards, it is characterized in that the agricultural liquid distributor made to absorb the refrigerant vapor evaporated from the surface of the cold water pipe to eject the heat of absorption to the inner wall surface of the first outer cylinder.

Can be.

Next, the effect of the absorption type air conditioner according to the first embodiment of the present invention configured as described above will be described.

In the cooling operation, since the high temperature and high pressure steam generated by the generator 65 is blocked at the branch pipe 86 side of the three-way solenoid valve 99, the upstream steam transfer pipe 74a and the two-way solenoid valve 88 are operated. And supplied to the first to fourth inner cylinders 64a to 64d through the downstream steam transfer pipe 74b and the branch pipes 74c to 74f, and condensed on the inner wall surface of the inner cylinders 64a to 64d, respectively. Heat of condensation is discharged to the outside by the air cooling fins 121a and 121b respectively disposed between 64a to 64d. The condensed refrigerant liquid is collected on the bottom surface of the inner cylinders 64a to 64d and collected to the first connecting pipe 71a on the upstream side through the branch pipes 71c to 71f, so that the three-way solenoid valve 99 and the downstream side agent are made. It flows into the refrigerant liquid distributor 60 disposed above the first outer cylinder 61 through the connecting pipe 71b of the third. The coolant introduced into the coolant liquid distributor 60 is a main portion of the first siphon member 130 disposed over the leading edges of both side wall portions of the coolant liquid distributor 60, as shown in detail in FIG. 4. And the space formed by the inner and outer sidewalls of the refrigerant liquid distributor 60 flows by siphoning action, and contacts the surface of the cold water pipe 77 wound and disposed with a predetermined gap in a spiral parallel structure at the bottom thereof. The evaporated water is introduced along the cold water introduction pipe 70 to cool the cold water flowing in the cold water pipe 77. On the other hand, the precooling agent from the generator 65 through the solution pump 89, the solution heat exchanger 66, the upstream agricultural solution discharge pipe 72a, the three-way solenoid valve 140 and the downstream agricultural solution discharge pipe 72b. The agricultural liquid supplied to the upper portion of the second outer cylinder 62 is cooled by air on the outer circumferential surface while flowing down the inner wall surface of the second outer cylinder 62 and flows downward to the upstream third connecting pipe 131a. ) And pumped by the pump 120 and supplied to the solution distributor 63 through the two-way solenoid valve 122 and the downstream third connecting pipe 131b to supply the second siphon member 138 and the solution. The heat transfer fin 76 flows along the inner wall of the first outer cylinder 61 attached in a helical shape through a gap (space) formed by the side wall portion of the distributor 63. At this time, the refrigerant flowing down from the refrigerant liquid distributor 60 absorbs the refrigerant vapor evaporated while being in contact with the surface of the cold water pipe 77 and changes into a rare solution.

In this way, the cold water introduced into the cold water pipe 77 through the inlet pipe 70 is cooled and supplied to the heat exchanger in the room through the discharge pipe 75 to cool the room.

In the above description, the three-way solenoid valve 140 is blocked on the downstream third connection pipe 131b side, of course, the downstream side concentration solution discharge pipe 72b side is open.

Then, the rare solution collected on the lower surface of the first outer cylinder 61 is introduced into the generator 65 after heat exchanged with the agricultural liquid in the solution heat exchanger 66 through the second connecting tube 96. It forms a cooling cycle, and the air flowing between each air cooling fins 121a and 121b disposed between the plurality of inner cylinders 64a to 64d removes the heat of condensation generated in the inner cylinders 64a to 64d and precools them. The solution temperature in the second outer cylinder 62 of the dragon is lowered and supplied to the inner wall of the first outer cylinder 61 to improve the absorption efficiency. At this time, the air is sucked through the air suction unit 79 formed in the lower portion of the second outer cylinder 62 by the driving of the cooling fan 68, and the respective inner cylinders 64a to 64d and the outer cylinder 61, Through the air cooling fins 121a and 121b disposed between 62, the heat of condensation of the inner cylinders 64a to 64d and the heat of absorption on the inner wall surface of the first outer cylinder 61 serving as an absorber are removed.

However, when the cooling effect of the air cooling fins 121a and 121b is not great, the temperature and pressure of the solution and the refrigerant in the first outer cylinder 61 and the plurality of inner cylinders 64a to 64d are increased. In the case where the absorption type air conditioner of the present invention is unstable in operation and there is a possibility that crystals are precipitated, it is detected by the temperature sensors 80 and 81 provided in the inner cylinders 64a to 64d and the second outer cylinder 62, respectively. The temperature is inputted to a microcomputer (not shown), and the cooling water pump 93 is operated under the control of the microcomputer, and the cooling water 83 stored in the cooling water storage plate 82 is transferred to the upper portion through the cooling water supply pipe 84. It is supplied to the sprayer 85 located. The sprayer 85 is a cant type, and rotates around the joint 200 in accordance with the pressure of the cooling water to spray the cooling water 83 around the air cooling fins 121a and 121b to remove the heat of condensation and absorption.

Next, during the heating operation, the driving of the cooling fan 68 and the spraying action from the sprayer 85 are stopped and at the same time, the high-temperature, high-pressure refrigerant vapor discharged from the generator 65 is blocked by the two-way solenoid valve 88. Since the upstream side of the first connecting pipe 71a of the three-way solenoid valve 99 is shut off, the upstream steam transfer pipe 74a, the branch pipe 86, and the three-way solenoid valve 99 are closed. And a refrigerant liquid distributor 60 disposed above the first outer cylinder 61 through the downstream first connection pipe 71b.

Accordingly, the high temperature and high pressure refrigerant vapor is condensed while flowing from the upper portion to the lower portion of the first outer cylinder 61 while producing condensation heat on the surface of the tube used as the cold water tube 77 at the time of cooling to form the refrigerant liquid. Therefore, the cold water flowing in the cold water pipe 77 is heated by the heat of condensation, and the heated hot water is supplied to the room through the discharge pipe 75 to be heated.

On the other hand, the solution heat exchanger 66, the upstream concentrated liquid discharge pipe 72a, the three-way solenoid valve 140 and the downstream third connection pipe 131b are driven by driving the solution pump 89 from the generator 65. The high temperature and high pressure concentrated solution flowing into the solution distributor 63 disposed in the first outer cylinder 61 is mixed at the bottom of the condensed refrigerant liquid and the first outer cylinder 61 to be discharged. In the course of passing through the connecting pipe 96, the heat exchanger with the concentrated solution in the solution heat exchanger 66 constitutes a cycle flowing into the generator.

Next, a second embodiment of the present invention will be described with reference to FIG. 3 schematically showing an absorption type air conditioner of the present invention. In addition, the same code | symbol is attached | subjected about the part same as the part shown in FIG. 1, and the overlapping description is abbreviate | omitted.

Each of the air cooling fins 121a and 121b disposed to cool the condensation heat generated in the inner cylinders 64a to 64d. The other operations are the same as those of the first embodiment shown in FIG. In the heating operation, it is configured to be the same as in the first embodiment.

As described above, according to the absorption type air conditioner according to an embodiment of the present invention, air cooling fins are respectively disposed between the internal cylinders of the high temperature and high pressure refrigerant vapor generated in the generator during the cooling operation, and toward the center of the plurality of internal cylinders. The inner cylinder is supplied through a branch pipe with a small diameter, and the inner cylinder disposed outside is configured to gradually supply high temperature and high pressure refrigerant vapor through a larger diameter, and at the same time, a spiral (screw-shaped) heating fin is provided inside. Air cooling fins are disposed on the outer circumferential surface of the first external cylinder, and the second external cylinder for pre-cooling the agricultural solution is concentrically disposed on the outer side of the air cooling fin.

Air cooling fins disposed between each inner cylinder acting as a condenser, a first outer cylinder acting as the inner cylinder and an absorber, and disposed between the first outer cylinder and a second outer cylinder. The air flowing around the air-cooled fins removes the heat of condensation condensed in the inner cylinder, and lowers the temperature of the concentrate in the second outer cylinder for pre-cooling the concentrate, thereby improving absorption and improving the cooling and heating efficiency of the system. At the same time there is an excellent effect that the structure is simple and easy to manufacture.

In addition, the absorption type air conditioner according to the present invention has a configuration in which a refrigerant liquid distributor and a concentrated liquid distributor are disposed on an upper portion of the first outer cylinder, and a siphon member is disposed in the refrigerant liquid distributor and the agricultural liquid distributor. Even if it is not installed horizontally precisely, it is possible to eject a uniform amount of refrigerant liquid onto the surface of the cold water pipe disposed in a spiral shape at the lower part thereof, and at the same time, to uniformly flow the agricultural liquid on the inner wall of the first outer cylinder. In addition to improving the cooling and heating efficiency, it is possible to uniformly drop the refrigerant in the refrigerant liquid distributor and the agricultural liquid in the agricultural liquid distributor onto the surface of the entire cold water pipe by the respective siphon members without precisely leveling them at the time of installation. There is an excellent effect that the work is very easy.
