Description

Technical Field

[0001] The present application relates to a prefabricated component and a heat exchange system with energy storage function. Background Art

[0002] At present, peak-valley electricity prices are generally implemented in China. The electricity price during peak hours is much higher than the unit price during valley hours. Therefore, it is more economical for energy-consuming products to operate during valley hours than during peak hours. However, energy-consuming products are subject to the needs of users during their usage periods, and valley electricity is often at night. Even during peak hours during the day, users will still turn on energy-consuming products to meet their needs. Therefore, the existing technology needs to consider how to allow energy-consuming products to operate during valley hours and store the converted energy in a physical way. During valley hours, it can be charged and discharged, and the stored energy can be released during peak hours to meet the needs of peak hours. However, with the increasing price of energy, it is also an urgent need for buildings to use energy economically by using peak-valley electricity prices, which is also highly consistent with the policy of peak-shaving and valley-filling electricity.

[0017] To make the purpose, technical solutions and advantages of this application more clear, the embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be noted that, unless there is a conflict, the embodiments and features in the embodiments of this application can be combined with each other in any way.

[0018] The prefabricated component of the present application includes an energy storage layer 1, a heat conductive layer 2 and a heat exchange component 3. The heat conductive layer 2 and the heat exchange component 3 are arranged in the energy storage layer 1 to form a prefabricated component, and the heat exchange component 3 is arranged between the heat conductive layers 2 or on the heat conductive layer 2. The energy storage layer 1 is formed into the required size of the prefabricated module by in-mold casting. Fiber reinforcement materials can be added to the mixed energy storage layer 1 to improve the strength of the prefabricated module. In order to increase the thermal conductivity of the energy storage material, materials such as metal powder or graphene can also be added to enhance the thermal conductivity of the prefabricated module. The energy storage material can be concrete or other materials that are mixed and solidified using one or more materials. One or both sides of the surface of the energy storage layer 1 can be smooth and used as a decorative layer of the floor; one or both sides of the surface of the energy storage layer 1 can also be rough. In order to form a good bite with the cast-in-place concrete during construction, texture or unevenness can be formed on the surface so that the cast-in-place concrete is embedded in the texture and the two form a good whole.

[0019] The heat-conducting layer 2 can be provided on at least one side of the heat exchange component 3, and the heat-conducting layer 2 can be made of a metal plate less than 1 mm or a metal film less than 0.1 mm. The heat-conducting layer 2 has good thermal conductivity, which can improve the heat exchange capacity between the heat exchange component 3 and the energy storage layer 1, thereby quickly transferring the energy in the heat exchange component 3 to the energy storage layer 1. Considering that the heat-conducting layer 2 is pre-buried in the energy storage layer 1, the surface of the heat-conducting layer 2 needs to be treated by lamination, coating, electrophoresis or electroplating to improve the corrosion resistance, and after the surface treatment, the heat-conducting layer 2 needs to form good bonding properties with the energy storage layer 1. In order to prevent the energy storage layer from being hollowed due to the heat-conducting layer, a through hole can be provided in the heat-conducting layer so that the energy storage material can pass through from top to bottom to form a fastening structure. Figure 3-5 As shown, the heat exchange component 3 may include at least one pipeline, and the heat conductive layer 2 may be flatly attached to the heat exchange component 3, or may be joined to the heat exchange component 3 in the form of heat exchange ribs or fins. Figure 1 As shown, a support member 4 may be provided on at least one side of the heat conducting layer 2 and the heat exchange component 3 to enhance the strength of the prefabricated component. The support member 4 may be in the form of a grid to improve the uniformity and integrity of the support.

[0020] like Figure 6-7As shown, the prefabricated component may include a bottom layer 11 and a top layer 12, and the heat-conducting layer 2 and the heat-exchanging component 3 are joined and arranged between the bottom layer 11 and the top layer 12. Specifically, the prefabricated module can be made by in-mold casting. First, a certain amount of energy storage material is placed in the mold to form the bottom layer 11, and then the bottom layer of the heat-conducting layer 2 is laid, and then the heat-exchanging component 3 is placed, and then the top layer of the heat-conducting layer 2 is covered, and then the energy storage material is cast to form the top layer 12. After the mold is closed, the bottom layer 11, the bottom layer 12, the heat-conducting layer 2, the heat-exchanging component 3, etc. are fixed and dried, and can be demoulded. During on-site construction, in order to further improve production efficiency, the heat-conducting layer 2 and the heat-exchanging component 3 can be prefabricated as a whole in advance, and the support member 4 can also be prefabricated as a whole together with the heat-conducting layer 2 and the heat-exchanging component 3. Prefabricated components can be equipped with additional installation structures such as hooks and holes according to installation requirements.

[0021] like Figure 6-9 As shown, the prefabricated component is also provided with at least one notch 14, and the inlet end 3A and the outlet end 3B of the heat exchange component are exposed from the notch 14. When multiple prefabricated components are spliced together, the inlet end 3A of one prefabricated module will be connected to the outlet end 3B of another prefabricated module, thereby forming a connection between the pipelines of the heat exchange components in multiple prefabricated modules. The heat exchange components between multiple prefabricated components can be connected in series or in parallel, and finally connected to the energy supply unit to realize the heat exchange medium transportation circulation of the heat exchange components of the prefabricated module, thereby continuously supplying the prefabricated module and storing energy in the prefabricated module. The functional unit can be an air source unit with refrigerant as the heat exchange medium; or it can be a water pump with water as the heat exchange medium to realize the energy supply to the prefabricated module and meet the energy demand of the prefabricated module when storing energy. Energy can be cooling or heat.

[0022] like Figure 6-10 As shown, the prefabricated component is also provided with a mortise and tenon structure, that is, a mortise structure 1A is provided on one side of the prefabricated component, and a mortise structure 1B is provided on the other side. When the two prefabricated components are spliced and assembled, the mortise structure 1A on one prefabricated component can match the mortise structure 1B on the other prefabricated component to form a positioning relationship to meet the size requirements of splicing multiple prefabricated components.

[0023] The present application also relates to a heat exchange system comprising the prefabricated components described above, and further comprising a liquid distributor. A plurality of the prefabricated components are connected to the liquid distributor in parallel, series, or a combination of series and parallel. The liquid distributor can be connected to an external heat exchange assembly using methods known in the art. The heat exchange medium is diverted through the liquid distributor to the heat exchange components of each prefabricated component. The external heat exchange assembly and the heat exchange components within the prefabricated components exchange heat, thereby achieving heat exchange in the target area.
