Description

Technical Field

[0001] The utility model relates to the field of new construction or renovation of high-efficiency machine rooms for energy-saving refrigeration and air-conditioning equipment in the high-efficiency energy-saving industry, and in particular to a laying structure for chilled water pipes in a standard high-efficiency machine room. Background Art

[0002] The introduction and implementation of standard high-efficiency computer rooms aims to save energy in air conditioning systems and reduce operating costs for cooling systems. In commercial and hotel buildings, cooling systems account for over 30% of total building energy consumption. However, the development of standard high-efficiency computer rooms in China is still in its early stages, and most buildings' air conditioning systems are still energy-intensive. Therefore, within the broader context of the "dual carbon" goals, the implementation of standard high-efficiency computer rooms is crucial for directly reducing resource consumption, better serving and supporting sustainable development goals, promoting ecological progress, and achieving harmonious coexistence between man and nature.

[0003] However, when building or renovating air conditioning rooms, the issues of chilled water pipe leakage and the devices and installation to prevent it remain largely unresolved. While solutions to these two issues exist in other fields, providing insights into the implementation of standard, high-efficiency equipment rooms, they still face the following challenges:

[0004] (1) The re-leakage of the chilled water pipes was not monitored, and the installation of the secondary structure was defective.

[0005] The phenomenon of chilled water pipe leakage, as well as the devices and methods for preventing it, has garnered widespread attention. Currently, the primary structures designed to prevent leakage on water pipes somewhat overlook monitoring for subsequent leakage after damage, and the design of secondary structures has also been neglected. For example, Chinese utility model patent CN215445591U discloses a wooden support for insulating and fixing drainage pipes, which prevents condensation from forming on parts of the pipe. However, this structure, which uses wooden supports and sealants for fixing and insulating, has limitations and neglects monitoring for subsequent leakage after damage to the insulation layer or fixing structure.

[0006] (2) The installation location of the chilled water pipe and the types of bolts and nuts were not fully considered.

[0007] The size of the bolts and nuts affects the force applied by the pipe clamps to the chilled water pipes and filler material. The installation position of the chilled water pipes affects the balance and force of the channel steel. Oversized bolts and nuts can damage the insulation and protective layers, while undersized bolts and nuts are insufficient to support the normal operation of the chilled water pipes. Currently, no design guidelines have been developed that consider the bolt and nut installation sizes for high-efficiency computer room chilled water pipes. Utility Model Content

[0008] The present invention aims to solve at least one of the above-mentioned technical problems in the prior art to a certain extent. The embodiment of the present invention provides a standard and efficient chilled water pipe laying structure for a computer room. An insulation layer and a protective layer are sequentially wrapped around the outer peripheral wall of the chilled water pipe to insulate the chilled water pipe and reduce the probability of the external environment damaging the insulation layer. The installation and fixation of the chilled water pipe are achieved by a pipe clamp, and the setting of a reconstructed wooden support can reduce the vibration effect caused by the change of water flow in the chilled water pipe. By setting a moisture-sensitive color-changing dye, cold leakage can be detected in time, thereby realizing the monitoring of the cold leakage phenomenon.

[0012] Preferably, the moisture-sensitive color-changing dye is disposed on the surface or inside of the reconstituted wood.

[0013] Preferably, the humidity-sensitive color-changing dye is cobalt chloride humidity-sensitive color-changing dye.

[0014] According to an embodiment of the first aspect of the present invention, the insulation layer is made of a flexible foam rubber-plastic material. The thickness of the insulation layer wrapped around the chilled water pipe can be calculated using the following formula:

[0015]

[0016] Where d is the diameter of the chilled water pipe, δ is the thickness of the insulation material, and t m is the average temperature of the insulation layer, t1 is the temperature of the cold medium in the chilled water pipe, t2 is the dry bulb temperature of the air in contact with the outer surface of the insulation material, t b It is the dew point temperature of the air that the outer surface of the insulation material contacts (the dew point temperature of the hottest month under local meteorological conditions).

[0017] According to the embodiment of the first aspect of the present utility model, the chilled water pipe can be laid in a vertical direction. During laying, the outer periphery of the chilled water pipe is fully wrapped by the insulation layer and the protective layer in sequence. The reconstructed wooden support wraps the protective layer with a certain gap according to construction requirements. The pipe clamp is tightly attached to the reconstructed wooden support and is fixed to one side of the mounting seat by a first bolt and a nut. The other side of the mounting seat is fixed to the vertical construction surface by an expansion bolt.

[0018] According to the embodiment of the first aspect of the present invention, the chilled water pipe can also be laid in a horizontal direction. During laying, the periphery of the chilled water pipe is fully wrapped by the thermal insulation layer and the protective layer in sequence. The reconstructed wooden support wraps the protective layer with a certain gap according to construction requirements. The pipe clamp is tightly attached to the reconstructed wooden support and is fixed to the upper end of the mounting seat by a second bolt and nut.

[0019] According to the embodiment of the first aspect of the present invention, tripods are welded on both sides of the lower end of the mounting seat, an embedded plate is welded at the bottom end of the tripod, and thick plates that fit together are welded at the junction of the mounting seat and the tripod.

[0020] The tripod is made of channel steel.

[0022] According to an embodiment of the first aspect of the present invention, when the chilled water pipe is laid in a horizontal direction, the size of the second bolt and nut is approximately twice as large as the size of the first bolt and nut when laid in a vertical direction; the models of the first and second bolts and nuts are determined according to the diameter of the chilled water pipe and the maximum allowable flow rate, and the installation spacing of the two chilled water pipes is the same as the distance between one of the chilled water pipes and the edge of the mounting base.

[0023] According to an embodiment of the first aspect of the present utility model, the specific length of the tripod is determined by the actual needs of on-site construction.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

In addition, the overall ambient temperature of the high-efficiency machine room is relatively low, so the combination structure of the reconstructed wood support structure and the moisture-sensitive color-changing dye has strong stability, durability and cooling leakage monitoring effect in this environment.

[0026] (2) The installation spacing of the chilled water pipes and the determination of the installation types of bolts and nuts can balance the interaction forces between the pipe clamps, mounting bases, chilled water pipes and reconstructed wooden supports, effectively reducing the damage to the insulation layer and protective layer, thereby further preventing the occurrence of cold leakage in the chilled water pipes, and contributing to the safe operation of the chilled water pipes and the safety of the equipment in the efficient machine room.

The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the entire technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

Therefore, it cannot be understood as a limitation on the present invention.

[0034] In the description of the present invention, it should be noted that, unless otherwise clearly defined, terms such as "setting", "installation", and "connection" should be understood in a broad sense, and technicians in the technical field can reasonably determine the specific meaning of the above terms in the present invention in combination with the specific content of the technical solution.

[0035] See also Figure 1-3 The utility model provides a standard and efficient laying structure for chilled water pipes in a machine room, comprising a chilled water pipe 2, an insulation layer 3, a protective layer 4, a mounting base 5, a reconstructed wooden support 6, a pipe clamp 7, a first bolt and nut 9, and a second bolt and nut 10. The periphery of the entire chilled water pipe 2 is wrapped by the insulation layer 3, and the periphery of the insulation layer 3 is wrapped by the protective layer 4 (in order to clearly show the structure of each layer in the figure, the insulation layer 3 and the protective layer 4 are not shown on some positions of the chilled water pipe 2). During laying, the chilled water pipe 2 is fixed to the mounting base 5 by the pipe clamp 7. The mounting base 5 is used to achieve fixation between the pipe clamp 7 and the position where the laying structure is to be laid, wherein the reconstructed wooden support 6 is provided at the contact point between the pipe clamp 7 and the protective layer 4 and at the contact point between the protective layer 4 and the mounting base 5, and a moisture-sensitive color-changing dye is provided in the reconstructed wooden support 6.

[0036] The pipe clamp 7 and the mounting seat 5 are fixed by means of bolts and nuts, and the mounting seat 5 and the construction surface are fixed by means of expansion bolts.

[0037] In some embodiments of the present invention, the mounting seat 5 is a channel steel.

[0038] In some embodiments of the present invention, the material of the protective layer 4 is aluminum.

[0039] In some embodiments of the present invention, the insulation layer 3 is made of a flexible foam rubber-plastic material, and the thickness of the insulation layer 3 wrapped around the chilled water pipe 2 can be calculated according to the following formula:

[0040]

[0041] Where d is the diameter of the chilled water pipe, δ is the thickness of the insulation layer, and t m is the average temperature of the insulation layer 3, t1 is the temperature of the cold medium in the chilled water pipe, t2 is the dry bulb temperature of the air in contact with the outer surface of the insulation layer, t b is the dew point temperature of the air in contact with the outer surface of the insulation layer (the dew point temperature of the hottest month under local meteorological conditions). This formula can be used to accurately determine the thickness of the insulation layer 3, which can further effectively prevent the chilled water pipe 2 from leaking cold and, to a certain extent, reduce the overweight problem caused by the excessive thickness of the insulation layer 3.

[0042] The periphery of the thermal insulation layer 3 is fully wrapped by the protective layer 4. In some embodiments of the present invention, the thickness of the protective layer 4 is 0.5 mm. The addition of the protective layer 4 can effectively reduce the probability of the external environment damaging the thermal insulation layer 3.

[0043] The reconstituted wood support 6 comprises reconstituted wood and a moisture-sensitive color-changing dye disposed on the reconstituted wood. Preferably, the moisture-sensitive color-changing dye is cobalt chloride. The cobalt chloride moisture-sensitive color-changing dye changes from blue to pink upon contact with water, and this color change is reversible, returning to its original color after dehumidification and drying. In some embodiments of the present invention, the main structure of the reconstituted wood support 6 is formed from ordinary wood using reconstituted wood technology, and the cobalt chloride moisture-sensitive color-changing dye is added to the surface or interior of the main structure via a soak-and-dry method. The reconstituted wood reduces the vibration caused by changes in the water flow rate of the chilled water pipe 2, and the reconstituted wood structure is easier to process. The addition of the cobalt chloride moisture-sensitive color-changing dye allows for timely detection of cold water leaks so that protective measures can be taken.

[0044] The diameter of the chilled water pipe 2 is mainly determined by the maximum flow rate and economic flow rate of the terminal equipment, but will be affected by the specific construction scenario.

[0045] The chilled water pipe 2 can be laid in a vertical direction or in a horizontal direction.

[0046] When the chilled water pipe 2 is laid in the vertical direction, please refer to Figure 1 The periphery of the chilled water pipe 2 is fully wrapped by the insulation layer 3 and the protective layer 4 in sequence. The reconstructed wooden support 6 wraps the protective layer 4 at a preset gap according to the construction requirements. The pipe clamp 7 is close to the reconstructed wooden support 6, and the pipe clamp 7 is fixed to one side of the mounting base 5 by a first bolt and a nut 9. The other side of the mounting base 5 is fixed to the vertical construction surface 1 by an expansion bolt 8.

[0047] The expansion bolt 8 is of the same model as the first bolt and nut 9, and the two are arranged in a one-to-one correspondence, which can improve the stability, durability, and safety of the structure. In some embodiments of the present invention, the expansion bolt 8 is an M16 expansion bolt, and the first bolt and nut 9 are of the same model.

[0048] When the chilled water pipe 2 is laid horizontally, refer to Figure 2 The periphery of the chilled water pipe 2 is fully wrapped by the insulation layer 3 and the protective layer 4 in sequence. The reconstructed wooden support 6 wraps the protective layer 4 at a preset gap according to the construction requirements. The pipe clamp 7 is close to the reconstructed wooden support 6. The reconstructed wooden support 6 is distributed on the periphery of the protective layer 4. The mounting seat 5 is located below the reconstructed wooden support 6. The pipe clamp 7 is installed on the upper side of the reconstructed wooden support 6. The mounting seat 5 and the pipe clamp 7 are fixed by welding with a second bolt and nut 10, and fit closely with the reconstructed wooden support 6.

[0049] In some embodiments of the present invention, the second bolt and nut 10 are bolts and nuts M24, the bracket 12 is made of channel steel, the embedded plate 13 is a steel plate, and the thick plate 11 is a thick steel plate. The specific length of the bracket 12 is determined by the actual needs of the on-site construction, not as Figure 2 The splicing structure shown, Figure 2 It has the effect of omitting length.

[0050] In some embodiments of the present invention, when the chilled water pipe 2 is laid in the horizontal direction, the pipe clamp is fixed to the upper end of the mounting base 5 by a second bolt and a nut 10, and brackets 12 are welded on both sides of the lower end of the mounting base 5, and an embedded plate 13 is welded to the bottom end of the bracket 12. At the junction of the mounting base 5 and the bracket 12, a thick plate 11 is welded to fit the mounting base 5 and the bracket 12.

[0051] In some embodiments of the present invention, when the chilled water pipe 2 is laid in the horizontal direction, the size of the second bolt and nut 10 is approximately twice the size of the first bolt and nut 9 when laid in the vertical direction. The model of the bolt and nut 9-10 is determined by the diameter of the chilled water pipe 2 and the maximum allowable flow rate.

[0052] The installation spacing of the two chilled water pipes 2 is the same as the distance between one of the chilled water pipes 2 and the edge of the mounting seat 5, which balances the physical forces applied or received by the pipe clamp 7, the mounting seat 5, the chilled water pipe 2 and the reconstructed wooden support 6, thereby improving the safety and reliability of the operation of the chilled water pipe 2.

[0053] The laying structure provided by the aforementioned embodiment of the present invention can be installed in the spare space of a standard high-efficiency machine room through a good connection between the mounting base, pipe clamps, bolts and nuts, and has a stable structure. It can also prevent and monitor the leakage of the chilled water pipe, providing scientificity for its laying.
