A method for managing the reinstallation of seasonal or limited-time ice skating rinks and their reinstallation, which suppresses the deterioration of thermal insulation performance due to the reinstallation of insulated structures.

Abstract

In seasonal ice skating rinks, the repeated setup and dismantling of the rinks meant that when the reused insulation structures were reinstalled in piping sections with different shapes and conditions, variations in compressibility, poor adhesion, or localized gaps could occur due to the deformation history formed in the elastic insulation material, potentially leading to a decrease in insulation performance. [Solution] According to the present invention, in seasonal ice skating rink facilities, even when the insulation structure is removed and reinstalled, the correspondence between the cooling pipes and the insulation structure can be maintained, enabling a stable and highly reproducible facility configuration for the setup work. This suppresses the deterioration of thermal insulation performance when the thermal insulation structure is reused, and allows for the maintenance of stable cooling performance.

Description

Technical Field

[0001] The present invention relates to seasonal or limited-term ice skating rink facilities, and particularly to a management technique for suppressing a decrease in heat insulation performance by reinstalling a heat insulation structure on a corresponding pipe section when the heat insulation structure provided for a cooling pipe through which a refrigerant or brine circulates is reinstalled after removal.

Background Art

[0002] In seasonal or limited-term ice skating rink facilities, the cooling pipes and peripheral equipment may be removed after the end of the operation period and reinstalled during the next operation. In such facilities, the arrangement shape and curvature of the cooling pipes may vary for each section, and the arrangement order and correspondence relationship of the heat insulation structures may change for each operation.

[0003] Since the heat insulation structure has elasticity, local compression marks and restoration marks are formed according to the curvature and outer shape of the section where it is once installed. Therefore, when it is transferred to a section with a different curvature or different support conditions, local gaps and over-compression are likely to occur. As a result, a decrease in heat insulation performance, condensation, an increase in heat inflow, and an increase in cooling load may occur.

[0004] When the heat insulation structure includes an elastic heat insulating material such as urethane foam, the heat insulation structure undergoes local compression deformation according to the curvature, outer diameter change, joint position, and support conditions of the pipe section to be installed. Therefore, when the heat insulation structure once installed in a specific section is reinstalled in a section having different shape conditions, non-uniformity of the compression ratio, uneven distribution of the contact pressure, or local gaps may occur, leading to an increase in heat inflow and condensation.

[0005] In general cooling pipe heat insulation, the heat insulating material is usually constantly arranged after construction, and repeated removal and reinstallation are not assumed. In contrast, in the case of seasonal or limited-operation ice skating rink facilities, the process of dismantling the rink after the end of the operating period and reinstalling it for the next operating period is repeated, so the insulation structure is also intended to be reused and reinstalled. Under these operating conditions, thermal insulation structures, including elastic thermal insulation materials, have a deformation history corresponding to the curvature, joint positions, and support conditions at the time of previous installation. Therefore, when reinstalled in piping sections with different shape conditions, variations in compression ratio, poor adhesion, or localized gaps are likely to occur, leading to a decrease in thermal insulation performance. This invention addresses the challenges inherent in repeated installation by assigning management information to each thermal insulation structure to maintain correspondences, and further by performing standard checks after reinstallation. This suppresses the deterioration of thermal insulation performance while ensuring the reusability of the thermal insulation structure and contributing to the reduction of maintenance costs. [Overview of the Initiative] [Problems that the invention aims to solve]

[0006] The present invention aims to provide equipment and operating methods that can stably maintain the correspondence between cooling pipes and insulating structures, even in operations involving the removal and reinstallation of insulating structures in seasonal or limited-time ice skating rink facilities. In particular, when insulating structures containing urethane-based insulation materials are repeatedly reused, changes in installation position and curvature tolerances with each setup can lead to uneven compression and adhesion of the insulation material, resulting in reduced insulation performance and variations in localized cooling efficiency.

[0007] For reusable elastic thermal insulation structures, ensure their repositioning to piping sections that match the deformation history formed during the previous installation, thereby suppressing the deterioration of thermal insulation performance caused by variations in compression ratio and adhesion between sections. [Means for solving the problem]

[0008] The seasonal or limited-time ice skating rink facility according to the present invention comprises cooling pipes for circulating a refrigerant or brine, and a plurality of heat insulating structures detachably arranged around the outer circumference of the cooling pipes, with each of the heat insulating structures being provided with management information to correspond to the shape conditions of a predetermined section of the cooling pipes. When removing the structure, the insulation structure is recovered while maintaining the correspondence between the management information and the piping section. When setting up the structure again, the insulation structure is reinstalled in a piping section having the same or equivalent shape conditions as the previous installation, based on the aforementioned correspondence. Furthermore, after reinstallation, the contact state, outer shape, or thermal insulation state between the thermal insulation structure and the cooling pipes shall be checked, and if the predetermined standards are not met, the thermal insulation structure shall be repositioned or replaced. [Effects of the Invention]

[0009] According to the present invention, in seasonal or limited-time ice skating rink facilities, even when the insulation structure is removed and reinstalled, the correspondence between the cooling pipes and the insulation structure can be maintained, enabling a stable and highly reproducible facility configuration for the installation work.

[0010] As a result, the insulation structure, including the urethane-based insulation material, is reinstalled each time under the same cooling piping section and curvature conditions, thus suppressing excessive compression and uneven stress concentration of the insulation material. As a result, the deterioration of thermal insulation performance associated with the reuse of the thermal insulation structure can be suppressed, making it possible to maintain stable thermal insulation performance and cooling efficiency over a long period of time.

[0011] This suppresses localized overcompression and insufficient adhesion during the reinstallation of the insulated structure, and stabilizes the contact between the insulation material and the piping. As a result, it is possible to suppress the decrease in thermal insulation performance over time while suppressing the increase in heat inflow, the rise in cooling load, and the occurrence of condensation.

[0012] Therefore, the provision of management information and post-installation verification in the present invention are not intended for the purpose of organizing components or managing work, but rather function as a technical means to suppress the deterioration of the thermal insulation performance of the reusable elastic thermal insulation structure. [Brief explanation of the drawing]

[0013] [Figure 1] This is a conceptual diagram showing the correspondence between a thermal insulation structure and a piping section based on management information and historical information, relating to one embodiment of the present invention. [Figure 2] This is a conceptual diagram showing a comparison between a conventional example in which an insulating structure was reinstalled in a piping section with different shape conditions and an example of the present invention in which it was reinstalled in a piping section with the same or equivalent shape conditions. [Figure 3] This is a conceptual diagram showing the correspondence between the insulation structure and the piping section, the suitability assessment, and the state after reinstallation. [Figure 4] This cross-sectional view shows the state of void formation when the device is reinstalled under different shape conditions, and the state of tight contact when the device is reinstalled under the same or equivalent shape conditions. [Modes for carrying out the invention]

[0014] In one embodiment, the thermal insulation structure is assigned management identification information consisting of a number, symbol, color, code, or a combination thereof. During setup, the insulated structures are sequentially placed in the corresponding cooling piping sections based on the management identification information. During removal, the insulated structures will be recovered while retaining the same management identification information, and will be repositioned in the same correspondence during the next installation.

[0015] The thermal insulation structure is composed of an elastic thermal insulation material that is compressible and deformable during installation and removal, and the shape and compression state of the material are set to conform to the shape of the corresponding cooling piping section. In this embodiment, by reinstalling the same thermal insulation structure under the same conditions each time, it is possible to suppress the cumulative deterioration of the deformation state of the thermal insulation material.

[0016] The management information may be managed as a table that associates at least the piping section number with the attribute information of the section. As the attribute information, the radius of curvature, bending angle, pipe diameter, joint position, support position, pipe gradient, upstream or downstream side distinction, etc. can be used. After removal, the heat insulation structures may be separately stored according to the corresponding attribute information.

[0017] After reinstallation, the contact state between the heat insulation structure and the cooling pipe, the continuity of the outer peripheral shape, or the heat insulation state can be confirmed. If the predetermined standard is not met, the heat insulation structure can be rearranged or replaced. The above confirmation may be performed by visual inspection, palpation, gap confirmation, confirmation of condensation or frosting, or confirmation of temperature distribution.

Example

[0018] Hereinafter, an example of the present invention will be described. In the seasonal installation type ice skating rink according to this example, a plurality of heat insulation structures are detachably provided on the outer periphery of the cooling pipes temporarily installed outdoors. These heat insulation structures are assigned numbers indicating the attachment and detachment order during installation and removal based on the laying order of the cooling pipes and the pipe connection relationship. During installation, by sequentially attaching the heat insulation structures according to a predetermined number order, variations in the work procedure can be suppressed. Also, during removal, by removing the heat insulation structures in the reverse order of the above order, workability can be improved and damage to the heat insulation structures can be prevented. Thus, according to this example, in a seasonal installation type ice skating rink where the installation and removal operations are repeated, the manageability and work reproducibility of the heat insulation structures can be improved.

[0019] Such numbering is not only for simple work order management but is used to reinstall each heat insulation structure to the piping section that conforms to the shape conditions at the previous installation and suppress the deterioration of the heat insulation performance.

[0020] The insulation structure may be marked with a barcode, two-dimensional code, wireless identifier, or other identification medium, and a database may be established corresponding to the identification medium to record the installation history, reinstallation history, shape conditions of the corresponding piping section, inspection results, deterioration status, replacement history, etc. for each insulation structure. When reinstalling, the feasibility of reinstalling, the need for repositioning, or the need for replacement of each insulation structure may be determined based on the history information recorded in the database.

[0021] Furthermore, the identification medium may be used as individual identification information to identify each thermal insulation structure or each segmented thermal insulation member on an individual basis. In this case, the database may record at least a portion of the following in correspondence with the individual identification information: installation history, removal history, reinstallation history, shape conditions of the corresponding piping section, inspection results, compression deformation history, contact condition, deterioration condition, water absorption condition, hardening condition, fracture condition, or replacement history. When reinstalling, this historical information may be used to determine whether each insulation structure or each segmented insulation component can be reused, reinstalled, rearranged, or replaced. [Industrial applicability]
