Detailed Description

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 single lithium bromide absorption refrigeration unit has a rectangular parallelepiped structure, and heat exchange components such as a regenerator, an evaporator, an absorber, and a condenser are arranged inside the single lithium bromide absorption refrigeration unit. The basic working principle is as follows: the lithium bromide solution and the pure water are used as a working substance pair, the pure water is used as coolant water, the lithium bromide solution is used as an absorption liquid, and the refrigeration is realized by evaporating and absorbing heat under the high vacuum environment by means of the pure water. The refrigerant absorbs heat and evaporates into vapor. The refrigerant vapor no longer has phase change heat absorption capacity, and therefore, is absorbed by the lithium bromide solution and then is heated and regenerated together with the lithium bromide solution. The refrigerant water absorbs heat and evaporates to become refrigerant vapor, and the refrigerant water can absorb heat and evaporate again after being condensed and changed back to liquid state. The refrigerant water absorbs heat and evaporates, absorbs, regenerates, condenses, absorbs heat and evaporates again, so the refrigeration cycle is continuously carried out. The refrigerating unit circulates and exchanges heat among the parts of the evaporator, the regenerator, the absorber and the condenser through a pipeline system of hot water, cooling water and cold water respectively so as to complete a refrigerating process, obtain energy from the outside, release heat to the outside and supply cold energy to the outside.

The absorption refrigeration unit shown in fig. 1 is provided with independent hot water, cold water, a cooling water pipeline system and a solution circulation system, is an independent and complete refrigerator, and can be independently installed and operated to provide the refrigeration power of the basic unit. Meanwhile, the system also has the capability of combining multiple units to form a large combined refrigeration matrix.

To accommodate this combination, the present invention provides a set of water flow interface groups on the upper 110, lower 120, left 130, and right 140 combining surfaces of the absorption refrigeration unit, respectively: a hot water inlet, a hot water outlet, a cold water inlet, a cold water outlet, a cooling water outlet, and a cooling water inlet. 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 outlet 115 and a cooling water inlet 116 respectively; a hot water inlet 141, a hot water outlet 142, a cold water inlet 143, a cold water outlet 144, a cooling water outlet 145, and a cooling water inlet 146 are similarly provided on the right combined surface 140. The lower combined surface 120 opposite to the upper combined surface 110 is provided with 6 identical water flow interfaces which are mirror symmetry with the upper combined surface 110, and the left combined surface 130 opposite to the right combined surface 140 is provided with 6 identical water flow interfaces which are mirror symmetry with the right combined surface 140. The design of symmetry about the top and bottom makes when two absorption refrigeration units are combined about or are combined about, and corresponding rivers interface can align each other and connect into an integral whole.

In fact, at least 2 of the 6 faces of the cuboid refrigeration unit can be provided as combined faces, each combined face being provided with a set of interface groups for connection with adjacent refrigeration units (or external energy media). Each interface group comprises 6 water flow interfaces, and in actual use, 4 water flow interfaces or other water flow interfaces can be used as an interface group to be arranged on a combined surface according to actual conditions.

Fig. 2 is an exploded partial view of the assembly of the absorption refrigeration unit of the present invention.

Fig. 2 shows the positional relationship between different water flow ports on the upper assembly surface 110 of the absorption refrigeration unit and their corresponding water supply pipes.

Taking hot water as an example: a hot water inlet pipe 211 is arranged below the hot water inlet 111, the hot water inlet pipe 211 forms a deformed S-shaped channel 230 on the upper combined surface 110, the right combined surface 140 and the front surface, and hot water is introduced from the

inlets

111 and 141, passes through the deformed S-shaped channel 230 and flows into a regenerator tube side (not shown in the figure) of the refrigerating unit from the regenerator inlet 220; the low-temperature hot water flowing out from the tube side of the regenerator and losing heat after heat exchange flows out from the hot water outlet 221 of the regenerator and then passes through the other variable S-shaped hot water outlet pipeline 212 to be communicated with the hot water outlet 111 of the upper combination surface and the hot water outlet 141 of the right combination surface.

Other water supply pipes, such as a cold water inlet pipe 213, a cold water outlet pipe 214, a cold water inlet pipe 215, and a cold water outlet pipe 216, are similar to the hot water inlet pipe 211, the hot water outlet pipe 212, and so on.

The lower assembly surface 120 has the same structure as the upper assembly surface 110, the water flow interface layout of the lower assembly surface 110 is in mirror symmetry with the upper assembly surface 110, the left assembly surface 130 has a similar structure as the right assembly surface 140, and the water flow interface layout of the lower assembly surface is in mirror symmetry with the right assembly surface 140.

Thus, the upper fuselage section 110 communicates with the corresponding ducts provided in the right section 140; the upper and left combining

surfaces

110 and 130, the lower combining surface 120 and the right combining surface 140, and the lower combining surface 120 and the corresponding pipes provided in the left combining surface 130 are also communicated with each other. The water flow connectors on the four surfaces and the built-in water flow pipeline form a four-way joint, so that the refrigerating unit can independently introduce or draw out hot water, cold water and cooling water from the four surfaces.

FIG. 3A is a schematic diagram of a two-way joint; fig. 3B is an enlarged cross-sectional view of the two-way joint connection structure of fig. 3A.

FIG. 3A shows a schematic diagram of a two-way joint; when the absorption refrigeration unit 313 needs to communicate with another absorption refrigeration unit 314, the connection interface is structured as shown in fig. 3B.

Taking the hot water inlet 111 as an example, the other water flow interfaces are the same. When the hot water inlet 111 needs to be connected with a hot water source, the corresponding hot water inlets 111 on two adjacent absorption refrigeration units are connected with the two-way joint 310; the two-way joint 310 is provided with a barb 311 and O-

rings

312, 315. When in connection, the reverse hook 311 is clamped on the inner wall of the water flow interface where the

refrigeration units

313 and 314 are positioned, so that the two-way joint 310 is ensured not to be separated from the port under the action of water pressure; and the tightness of the two connected water flow ports 111 is ensured by the two O-shaped sealing rings 312 and 315.

FIG. 4 is a schematic view of the water flow interface in the off state of the present invention

When a certain water flow interface on the combined surface of the absorption refrigeration unit is not required to be communicated with the outside, the interface is in a closed state for preventing liquid from flowing out because the inside of the water flow interface is communicated with the corresponding water flow interfaces of other combined surfaces. In fact, all the water flow interfaces on the combined surfaces (110, 120, 130, 140) are integrally sealed in an injection molding mode in the initial state, and when a certain interface is required to be connected with the outside, a special tool is used for opening the interface.

A special tool positioning hole 431 and a reserved circular mark 432 are reserved on the closed interface, and the interface can be opened along the circular mark 432 by a special tool (not shown in the figure) and then connected by using the two-way connector 310.

Taking

hot water inlets

111 and 141 as an example, when the hot water inlet 111 is required to be used in installation, a special tool is used to open the interface and connect the two-way connector 310; the hot water inlet 141 is not required to be used and is in a closed state.

Although the invention will be described with reference to the specific embodiments shown in the drawings, it will be understood that many variations of the water flow interface of the absorption refrigeration unit, and the absorption refrigeration unit and absorption refrigeration matrix using the same, are possible, such as changing the placement of the water flow interface on each combining surface, etc., without departing from the spirit, scope and context of the teachings of the invention. Those of ordinary skill in the art will also recognize that there are different ways to alter the parameters, dimensions, etc. of the disclosed embodiments of the invention, yet still fall within the spirit and scope of the invention and the claims.
