The accompanying drawings form a part of this specification; various embodiments of the present invention will be described below with reference to the accompanying drawings. It is to be understood that for convenience of description, terms such as "front", "rear", "upper", "lower", "left", "right", and the like are used herein to describe various example structural components and elements of the invention, but such terms are merely determined according to the example orientations shown in the figures. Since the disclosed embodiments of the invention may be arranged in a variety of orientations, these directional terms are used by way of illustration only and are in no way limiting. Wherever possible, the same or like reference numerals are used throughout the present disclosure to refer to the same parts.

as shown in fig. 1, the external shape of the refrigeration unit is a cuboid structure. The inside of the rectangular machine body is provided with a regenerator, a condenser, an evaporator, an absorber, a solution heat exchanger, a solution tank and the like. The refrigerating unit is an independent absorption refrigerator, and the nominal refrigerating power is 4RT (simply called unit power) and is a refrigerating matrix with 1X 1 dimension. Meanwhile, the plurality of refrigeration units can be freely combined and seamlessly expanded in the horizontal direction and the vertical direction to form an n multiplied by m dimension refrigeration matrix with the power of n multiplied by m times of the unit power. Wherein seamless refers to a close fit.

In fact, at least 2 of the 6 faces of the rectangular parallelepiped refrigerating unit may be provided as combined faces, and at most 6 faces may all be provided as combined faces, as shown in fig. 12. Each combination surface is provided with a group of interfaces for connecting with adjacent refrigeration units (or external water sources). In practical use, the water flow interfaces with the number of 4 or other water flow interfaces are used as an interface group to be arranged on one combined surface.

In order to realize the combination of the units with each other, as an example, the refrigerating unit is provided with four combination surfaces: upper combining surface 110, left combining surface 120, lower combining surface 130, and right combining surface 140. A group of interface groups are respectively arranged on the four combined surfaces: a hot water inlet, a hot water outlet, a cold water inlet, a cold water outlet, a cooling water inlet, and a cooling water outlet. Taking the upper 110 and right 140 combining surfaces as can be seen in fig. 1 as an example: the upper combination surface 110 is provided with a hot water inlet 111, a hot water outlet 112, a cold water inlet 113, a cold water outlet 114, a cooling water inlet 115 and a cooling water outlet 116 respectively; the right combining surface 140 is provided with a hot water inlet 121, a hot water outlet 122, a cold water inlet 123, a cold water outlet 124, a cooling water inlet 125 and a cooling water outlet 126, respectively. In fact, the lower combined surface 130 opposite to the upper combined surface 110 is provided with 6 identical water flow interfaces mirror-symmetrical to the upper combined surface 110, and the left combined surface 120 (back surface) opposite to the right combined surface is provided with 6 identical water flow interfaces mirror-symmetrical to the right combined surface 140. The design of symmetry of the upper, lower, left and right is that when two refrigeration units are combined up and down or combined left and right, the corresponding water flow interfaces can be directly aligned and connected into a whole.

In addition, in the embodiment of the present invention, hot water, cold water, cooling water are used as energy medium for energy transfer between the refrigerating unit and the outside or adjacent refrigerating units, and in fact, other gases such as hot gas, cold gas, cooling gas, etc. may be used as energy medium of the present invention.

in fig. 2A, a plurality of water flow channels (i.e., internal channels) formed by matching with the wall plate of the shell are hidden in the upper combining surface 110 of the absorption refrigeration unit; a hot water inlet pipe 211, a hot water outlet pipe 212, a cold water inlet pipe 213, a cold water outlet pipe 214, a cooling water inlet pipe 215, and a cooling water outlet pipe 216, respectively. These water flow channels are respectively in communication with hot water inlet 111, hot water outlet 112, cold water inlet 113, cold water outlet 114, cooling water inlet 115 and cooling water outlet 116 in fig. 1. The bottom of the water flow channel is marked with marks H1, H2, L1, L2, M1 or M2 respectively.

Similarly, in fig. 2A, a plurality of water flow channels formed by matching with the wall plate of the shell are hidden in the right combining surface 140 of the refrigeration unit; a hot water inlet pipe 221, a hot water outlet pipe 222, a cold water inlet pipe 223, a cold water outlet pipe 224, a cooling water inlet pipe 225, and a cooling water outlet pipe 226, respectively, and are respectively communicated with the hot water inlet 121, the hot water outlet 122, the cold water inlet 123, the cold water outlet 124, the cooling water inlet 125, and the cooling water outlet 126 described in fig. 1.

The hot water inlet pipe 211 and the hot water inlet pipe 221 on the upper combined surface 110 and the right combined surface 140 form a right-angle elbow at the corners of the two combined surfaces, so that the hot water pipes in the two side surfaces are communicated together; the same is true of the cold water and the cooling water pipelines, and the description is omitted.

In this way, the

hot water inlets

111, 121, … … on the four combined surfaces are connected to the inlet of the regenerator 201 through hot water inlet pipes 211, 221, … …, etc. which are communicated with each other, to supply heat energy to the refrigeration unit; the four

cold water inlets

113, 123 … …, etc. of the cold water are connected to the inlets of the evaporator 203 by cold water inlet pipes 213, 223 … …, etc.; the four

cooling water inlets

115, 125, … …, etc. of the cooling water are connected to the inlets of the condenser 202 and the absorber 204 through the cooling water inlet pipes 215, 225, … …, etc.; therefore, the refrigerating unit can simultaneously or separately feed in or discharge hot water, cold water and cooling water from any combination surface. In other words, the refrigerating units can be attached and connected with one another through any one combination surface to form a refrigerating matrix.

in fig. 2B, the exterior surfaces shown in fig. 1 and 2A are removed, exposing the major components of the refrigeration unit of the present invention: comprising a regenerator 201, a condenser 202, an evaporator 203, an absorber 204, a solution fill port 205 (132 in fig. 1), a solution pump 206, a solution tank 207, a solution heat exchanger 208, and a solution delivery conduit 209. Wherein the regenerator 201 and the condenser 202 are arranged at the upper part of the cavity, and the evaporator 203, the absorber 204, the solution filling port 205, the solution pump 206 and the solution tank 207 are arranged at the lower part of the cavity; the pressure in the upper part of the chamber is higher than the pressure in the lower part of the chamber, separated from each other by a partition 241.

FIGS. 3A and 3B are respectively schematic diagrams of standard water flow interfaces of hot water, cold water and cooling water of upper and lower combined surfaces of a refrigeration unit according to the present invention

As can be seen in fig. 3A and 3B, the six standard water flow interfaces (H1, H2, L1, L2, M1, M2) on the upper and lower combining surfaces 110 and 130 (bottom view) are mirror images of each other; thus, when one refrigeration unit is combined with the other unit up and down, the standard water flow interfaces (ports) on the upper and lower faces of the two units can be precisely aligned;

the initial state of the standard water flow interface is a closed state. When a certain water flow interface needs to be opened, a special tool (not shown in the figure) can be used for cutting the seal of the water flow interface to be opened, and then the two-way connector is connected.

FIG. 3C is a schematic view of a two-way fitting for a refrigeration unit of the present invention; FIG. 3D is a schematic diagram of a two-way structure of the present invention for connecting standard water flow connectors on both sides;

as can be seen in fig. 3C, 3D, the refrigeration unit 313 needs to be combined up and down with another refrigeration unit 314; six water flow ports on the lower combination surface of the refrigeration unit 313 are required to be connected by six two-

way connectors

310 and 314. Taking a hot water inlet H1 as an example (other water flow interfaces are the same as the hot water inlet H1), firstly cutting and opening the H1 interfaces of the lower combined surface and the upper combined surface 314 of the refrigeration unit 313 by a special tool, and then connecting a two-way joint 310, wherein a reverse hook 311 and O-shaped sealing rings 312 and 315 are arranged on the two-way joint 310. When in connection, the inverted hook 311 is clamped on the inner wall of the water flow interface where the

refrigeration units

313 and 314 are positioned to form a self-locking structure; the tightness of the two connected water flow interfaces H1 is ensured by two O-shaped sealing rings 312 and 315.

The two

refrigeration units

313 and 314 combined up and down are connected with the external water supply pipeline, and can be connected by adopting the same two-way joint 310 by using water flow interfaces which are not used by any one (or a plurality of) of the

refrigeration units

313 and 314.

Fig. 3E and 3F are schematic diagrams of standard water flow interfaces of hot water, cold water and cooling water of the left and right combination surfaces of the refrigeration unit of the present invention.

As shown in fig. 3E and 3F, the six standard water flow interfaces (H1, H2, L1, L2, M1, M2) on the left and right combining

surfaces

120 and 140 are mirror images of each other; thus, when one refrigeration unit is juxtaposed side-by-side with the other, the standard water flow interfaces on the left and right combination surfaces of the two units can be precisely aligned. The water flow interface is connected in the same way as described in fig. 3B.

It should be noted that, the square hole of the solution heat exchanger 135 is reserved in the middle of the right combining surface 140, but not in the left combining surface 120. That is, the solution heat exchanger 135 is mounted within the housing of the fuselage where the combining surface 140 is located.

FIG. 4A is a front perspective view of the exposed water flow channel with the outer shell wall plate removed from the refrigeration unit; FIG. 4B is an enlarged view of a portion of region E of FIG. 4A;

as shown in fig. 4A and 4B, the externally supplied hot water flows into the inlet 251 of the tube side of the regenerator 201 through the hot water inlet pipe 211, and the right-angled elbow marked with H1 at the bottom of the tank at the upper and right parts, respectively, and the hot water partition 261 provided on the front panel; the low-temperature hot water flowing out from the tube side outlet 252 of the regenerator 201 flows back to the external heat source from the hot water outlet pipeline 212 through the elbow bend H2; thus, a complete heating path is formed.

A vacuum gap 271 with a width of 3.5-4.5 mm is provided between the hot water inlet pipe 211 and the hot water outlet pipe 212 to ensure heat insulation between high and low temperature hot water.

FIG. 4C is a rear perspective view of the exposed water flow channel with the cover plate removed from the refrigeration unit; FIG. 4D is an enlarged view of a portion of region F of FIG. 4C;

as shown in fig. 4C and 4D, cold water supplied from an external load enters the tube side of the evaporator 203 through the cold water inlet pipe 213 and the open hole 253 on the rear panel; the low-temperature cold water flowing out from the tube side 254 of the evaporator 203 flows back to the external load through the hot water outlet pipeline 212; in this way, a complete cold water path is formed.

The cooling water passage is similar to the hot water passage and the cold water passage.

as shown in fig. 5A, the solution heat exchanger 505 has a small thickness, and can be completely embedded in the solution heat exchanger 135 in the rectangular area on the machine body where the right combination surface 140 of the refrigeration unit is located in fig. 1, and is a part of the right combination surface 140 of the machine body, so that the heat exchange function is completed and the strength of the machine body is increased.

In fig. 5A, the solution delivery pipe 509 of the solution heat exchanger, which is also a part of the right combining surface 140 of the refrigerating unit, is completed together during molding of the body, and the cross-sectional form factor thereof also plays a role in reducing the weight of the body and enhancing the strength of the body while completing the function of delivering the solution.

In fig. 5A, the solution tank 510 is located at the lower part of the cavity of the refrigeration unit, that is, at the lower parts of the evaporator 203 and the absorber 204, and during the operation of the refrigeration unit, the solution naturally flows back to the solution tank 510 depending on the self weight, and no solution remains in other parts of the cavity except the solution tank 510 during long-term placement or even during transportation.

in fig. 5B, heat exchange wall plate 520 is embossed with dense, regular, textured ribs 522. The ribs 522 serve to support the heat exchange wall panel to withstand vacuum pressure and to cause turbulence in the fluid flowing past the ribs to increase the heat transfer coefficient.

In fig. 5B, the flow-blocking gasket 512 blocks the two circular

water flow ports

501 and 504 on the diagonal of the heat exchange wall 520, allowing only the hot solution from the regenerator solution outlet 514 to flow from the port 506 connected to 514 to the solution heat exchanger, then to the port 502 in the diagonal direction of the heat exchange wall, and then to the absorber 204 via the pipe 508 connected to 502 and sprayed. Adjacent to the other channel, the flow-blocking gasket 512 is turned 180 in the vertical direction (not shown); while blocking both

ports

502 and 506, only low temperature dilute solution is allowed to flow from circular water port 501 into the solution heat exchanger under the action of solution pump 503, then flows diagonally to circular water port 504, and then flows to the regenerator solution inlet via pipe 509 connected to circular water port 504 and sprays.

FIGS. 6A, 6B, and 6C illustrate a throttle device 600 according to the present invention, and in combination with FIG. 2B, the throttle device 600 is disposed on the baffle 241 in FIG. 2B, at the bottom of the condenser 202; on the side facing the condenser 202, the throttle device 600 further comprises a narrow elongated irregular V-shaped groove 601; the depth of the V-shaped groove 601 gradually increases from two sides to the middle position, and a circular through hole 602 with the diameter of 2-2.5 mm is formed in the deepest part of the throttling device 600; the circular through holes 602 are always sealed by the refrigerant water body, so that the mutual channeling of high-temperature refrigerant vapor in the condenser and low-temperature refrigerant vapor in the evaporator is blocked, and the normal operation of the evaporator 203 is ensured.

The chilled water generated by the condenser 202 will be deposited in the V-groove 601; according to the change of the flow rate of the refrigerant water, the height of the liquid accumulation in the V-shaped groove 601 is correspondingly changed, and the flow rate is regulated by the liquid accumulation height of the V-shaped groove 601.

On the side facing the evaporator 203, the orifice 602 gradually enlarges in diameter, forming an inverted horn 603. The refrigerant water generates a great pressure drop when flowing through the orifice 602, ensures that the refrigerant water is reduced from the regeneration pressure with higher pressure to the lower saturation pressure required by evaporation, and realizes the function of throttling and depressurization. At the same time, the inverted horn 603 also makes the orifice 602 less prone to fouling.

Fig. 7A is an assembly view of a regenerator 201 and a condenser 202 in a refrigeration unit according to the present invention; FIG. 7B is an enlarged view of a portion of the area encircled in FIG. 7A;

the first row of heat exchange tubes of condenser 202 in FIGS. 7A and 7B have been removed to show the bottom detail of channels 702. The regenerator 201 is formed by uniformly arranging heat exchange tubes 704 which are made of stainless steel tubes with nominal external diameter of 3mm in space to form a shell-and-tube heat exchanger which is formed by a 15X 36 heat exchange tube array; the arrangement of the heat exchange tubes of the condenser 202 is almost the same as that of the regenerator 201, except that the center line of the heat exchange tube 701 forms an inclination angle of 0-10 degrees with the horizontal direction; a diversion trench 702 is arranged between the upper row and the lower row of the

heat exchange tubes

701 and 704; the flow guide groove 702 traverses the regenerator 201 and the condenser 202.

In fig. 7B, a solution distributor 711 is provided at the upper portion of the heat exchange tube 704 of the first row of the regenerator 201; the solution distributor 711 is provided with four rows of 12 rectangular drain holes 712; the dilute solution supplied from the solution heat exchanger first flows into the solution distributor 711 and is uniformly distributed to the heat exchange pipes 704 through the 12 drain holes 712. Thereafter, the function of the solution distributor 711 is replaced by the diversion trench 702. A rectangular drain hole 712 which is the same as the solution distributor 711 is arranged at the bottom of the diversion trench 702; each row of rectangular drain holes on the diversion trench 702, each row of rectangular drain holes on the solution distributor 711 and each row of rectangular drain holes on the subsequent diversion trench are distributed in a staggered manner; the solution can not directly drop from the last drainage flow hole to the next drainage flow hole, but flows in a 'I' -shaped route, so that the contact time between the solution and the heat exchange tube is greatly prolonged, and the solution is ensured to have enough time for heat exchange and release the refrigerant.

In fig. 7B, support bars 713 with an inclination angle of 45 ° to 135 ° are provided at the bottom of the solution distributor 711, which are both support for the heat exchange tubes and serve to guide the flow, so that the solution is forced to be continuously redirected in the flow guide, thereby achieving the effects of increasing local turbulence and enhancing heat transfer.

In fig. 7B, the condenser 202 is not provided with a solution distributor, but is provided with a diversion trench, and the diversion trench is slightly different from the diversion trench of the regenerator 201 in shape: the heat exchange tube 701 and the diversion trench 702 of the condenser 202 have an inclination angle of 0-10 degrees with the horizontal direction so as to conveniently drain condensed water. At the bottom edge of the condenser 202, a chilled water drain hole 721 is provided; the coolant vapor evaporated from the regenerator 201 is cooled and condensed into coolant by the condenser 202 by the coolant drain holes on each row of the guide grooves aligned with each other in the vertical direction, and the coolant directly drops into the guide groove at the lowest layer of the condenser 202 and the throttling device 602 shown in fig. 6 under the action of gravity along the coolant drain holes 721, is throttled and depressurized by the throttling device 602, and then flows to the evaporator 203. A slope type liquid separation plate 703 is arranged between the heat exchange pipes of the regenerator 201 and the condenser 202; droplets entrained in the refrigerant vapor generated in the regenerator 201 are blocked back by the baffles 703, allowing only vapor to enter the condenser 202.

The

heat exchange pipes

704 and 701 of the regenerator 201 and the condenser 202 have a pipe center distance of 3.5-4.5 mm in the horizontal direction; the pipe center distance in the vertical direction is 6.5-7.5 mm. The heat exchange tubes are arranged in high density and have large heat transfer area per unit volume.

FIG. 8A is an assembly view of an evaporator and an absorber in a refrigeration unit of the present invention; FIG. 8B is an enlarged view of a portion of the K region of FIG. 8A;

the first row of heat exchange tubes in fig. 8A, 8B has been removed to show the bottom detail of the channels. The evaporator 203 and the absorber 204 are made of SS304 stainless steel pipes with nominal external diameter of 3mm, and the heat exchange pipes 801 are uniformly arranged into a 15 x 36 heat exchange pipe array in space to form a shell-and-tube heat exchange structure; a diversion trench 802 is arranged between the upper row of heat exchange tubes 801 and the lower row of heat exchange tubes 801; the flow guide groove 802 traverses the evaporator 203 and the absorber 204.

The upper part of the absorber 204 in fig. 8B is provided with a solution distributor 803, and the solution distributor 803 has the same shape and function as the solution distributor 711 in the regenerator 201 in fig. 7, and will not be described again here.

In fig. 8B, the evaporator 203 is not provided with a distributor, and the bottom of the flow guide groove 802 of the evaporator 203 is not provided with an inclination angle similar to that of the flow guide groove 702 of the condenser 202 in fig. 7, and the flow guide groove 802 is formed as a flat bottom shallow groove 811 on the side of the evaporator 203. In the middle of the flow guide groove 802 of the evaporator 203, a slope type liquid separation plate 805 is arranged, and liquid drops carried in refrigerant vapor generated in the evaporator 203 are blocked back by the slope type liquid separation plate 805, so that only vapor is allowed to enter the absorber 204. Meanwhile, four inverted triangle drain holes 806 are arranged on one side of the slope type liquid separation plate 805 facing the evaporator 203, and are used for uniformly discharging the coolant water in the diversion trench 802 to the surface of the lower heat exchange tube, performing heat exchange with the lower heat exchange tube by flowing in the shallow trench of the lower layer, and diversion and distribution are performed on coolant water effusion through the diversion trench 802, so that the coolant water uniformly infiltrates and flows through each row of heat exchange tubes.

The inverted triangle drain hole 806 can automatically adjust the deposition height of the coolant fluid in the flat bottom shallow groove 811 according to the coolant water flow rate: when the flow rate of the refrigerant water is large, the liquid height can reach the upper part of the inverted triangle hole, and the liquid discharge amount is increased; when the flow rate of the refrigerant water is smaller, the liquid level is low, and the liquid discharge amount is reduced through the lower part of the inverted triangle hole. The refrigerant water can uniformly infiltrate the heat exchange tube 801 when the refrigeration load is small and the refrigerant flow is small, so that the occurrence of dry spots on the surface of the heat exchange tube is reduced, and the evaporation heat transfer coefficient is improved.

The heat exchange tubes 801 of the evaporator 203 and the absorber 204 have a tube center distance of 3.5 to 4.5mm in the horizontal direction; the pipe center distance in the vertical direction is 6.5-7.5 mm. The heat exchange tubes are arranged in high density and have large heat transfer area per unit volume.
