Description

Technical Field

[0001] This utility model relates to the field of indoor ice rink technology, and in particular to an indoor ice rink temperature control structure. Background Technology

[0002] With the popularization and development of winter sports, the demand for indoor ice rinks, as important sports venues, is increasing. Traditional indoor ice rink temperature control structures typically use a simple combination of ice layers and cooling pipes, but this has revealed many problems in actual use.

[0003] On the one hand, insufficient temperature control precision and unreasonable refrigeration pipe layout lead to uneven ice surface temperature, resulting in localized melting or cracking, which seriously affects the quality of the ice surface and the skating experience. On the other hand, poor structural durability and lack of effective moisture-proof and heat-insulating design make the ice rink susceptible to external moisture and heat erosion during long-term operation, accelerating structural damage and increasing maintenance costs and frequency.

[0004] Furthermore, traditional temperature control structures consume a lot of energy, and the refrigeration and heating systems interfere with each other, resulting in significant heat loss. This not only wastes energy but also increases the operating costs of ice rinks, making it difficult to meet the current demands for energy conservation, environmental protection, and high-quality operation. Therefore, there is an urgent need to develop a new type of indoor ice rink temperature control structure that can accurately control temperature, has a stable structure, and saves energy.

Detailed Implementation

[0017] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0018] Example: A temperature control structure for an indoor ice rink, such as Figure 1 As shown, the system includes an ice surface layer 1, an ice paint layer 2, a leveling layer 3, a pressure-bearing and temperature-conducting module, a thermal insulation layer 7, a low-temperature crack-resistant stress-absorbing layer 8, a rigid support layer 9, a first waterproof layer 10, a water collection layer 11, a hydrophobic layer 13, a heating layer 14, a drainage pipe 15, and a base surface 19. The ice surface layer 1 serves as the direct load-bearing surface for skating activities, with the ice paint layer 2 tightly bonded to its lower surface. The ice paint layer 2 is evenly applied beneath the ice surface layer 1 using a spraying process, creating a seamless connection between the two. The ice paint layer 2 protects the ice surface and enhances its smoothness. The leveling layer 3, made of cement-based material, is laid beneath the ice paint layer 2 and has a thickness of 3-5 cm. The leveling layer 3, relying on the bonding properties of cement-based materials, firmly adheres to the ice paint layer 2, providing stable and reliable support for the ice surface layer 1 and ice paint layer 2 above. A pressure-bearing and temperature-conducting module is located below the leveling layer 3. The insulation layer 7 is positioned below the pressure-bearing and temperature-conducting module, effectively blocking external heat transfer, reducing heat exchange, and maintaining the low-temperature environment inside the ice rink. The low-temperature crack-resistant stress-absorbing layer 8 is carefully constructed of elastic polyurethane material, with a thickness of 5-8 cm and a Shore A hardness of 30-50. Lay at the bottom of the insulation layer 7, it can sensitively sense and absorb stress caused by temperature changes, preventing structural cracking due to stress concentration. To prevent cracking, a rigid support layer 9 is fixedly connected to the bottom of the low-temperature crack-resistant stress-absorbing layer 8 via anchors. The rigid support layer 9 provides rigid support and enhances the overall stability of the structure. The first waterproof layer 10 has a U-shaped structure and is directly connected to the rigid support layer 9. Its edges extend upwards to the sidewalls of each layer, forming a continuous waterproof barrier. The water collection layer 11 is placed below the first waterproof layer 10 and is responsible for collecting any water that may seep down, preparing for subsequent drainage. The polymer moisture-proof and vapor-proof layer 12 is connected to the bottom of the water collection layer 11. Utilizing its own material properties, it effectively blocks moisture and water vapor, preventing them from adversely affecting the structure. The lower surface of the polymer moisture-proof vapor barrier layer 12 is connected to a hydrophobic layer 13, which is used to guide water to drain quickly and avoid water accumulation. The heating layer 14 is connected to the bottom of the hydrophobic layer 13. The heating layer 14 has a pre-embedded drainage pipe 15. The top of the drainage pipe 15 has multiple water inlets 16 along the circumference. The water inlets 16 are embedded in the hydrophobic layer 13. The drainage pipe 15 and the water inlets 16 are used to drain accumulated water and supply water or other media, respectively. Together with the hydrophobic layer 13, the water collection layer 11, etc., it realizes the functions of drainage and media supply. The foundation ground 19 is located at the bottom layer. It is a concrete base with a surface that is completely attached to the upper structure and bears the overall structural load.

[0019] like Figure 1As shown, the pressure-bearing and temperature conduction module includes a pressure-bearing layer 4, a protective layer 5, and refrigeration pipes 6. The pressure-bearing layer 4 is located below the leveling layer 3 and is formed by casting high-strength concrete. The top bears the ice surface load, and the bottom is covered by the protective layer 5. Multiple refrigeration pipes 6 are evenly spaced inside the protective layer 5. The refrigeration pipes 6 are fixed in the protective layer 5 by means of brackets or adhesives, and then precisely connected to the external refrigeration system through welding joints. The lower surface of the protective layer 5 is directly connected to the insulation layer 7, which plays a role in protecting the refrigeration pipes 6 and assisting in temperature conduction.

[0020] like Figure 1 As shown, it also includes a second waterproof layer 17 and a moisture-proof layer 18. The second waterproof layer 17 is made of modified bitumen roll material and is fully laid on the bottom of the heating layer 14 to further enhance the waterproof performance and effectively block water vapor penetration that may occur in the heating layer 14 and the upper structure. The moisture-proof layer 18 is made of bentonite waterproof blanket and is set at the bottom of the second waterproof layer 17. The second waterproof layer 17 and the moisture-proof layer 18 are joined by hot-melt overlap to form a double layer of protection. The bottom of the moisture-proof layer 18 is fixed to the foundation ground 19 by concrete pouring, effectively blocking moisture from penetrating upward from the foundation ground 19.

[0021] During the refrigeration process, the external refrigeration system delivers a low-temperature medium into the freezing pipe 6. The freezing pipe 6, through heat conduction with the pressure-bearing layer 4 and the protective layer 5, gradually reduces the temperature of the ice surface layer 1, thereby creating and maintaining the required low-temperature environment for the ice surface. The insulation layer 7 plays a crucial role in this process, greatly reducing the transfer of external heat and ensuring the stability and efficiency of the refrigeration effect. When the ice rink needs to be heated, such as during ice surface maintenance or seasonal changes, the heating layer 14 begins to work, releasing heat to meet the heating demand. Regarding moisture prevention and drainage, the first waterproof layer 10, the second waterproof layer 17, the polymer moisture-proof vapor barrier layer 12, and the moisture-proof layer 18 form a tight moisture-proof system, comprehensively preventing moisture and humidity from intruding into the structure. The water collection layer 11, the hydrophobic layer 13, and the drainage pipe 15 work together to efficiently collect and quickly drain accumulated water, ensuring the interior of the structure remains dry, thus guaranteeing the stable operation of the temperature control structure.
