Application Area
Concrete pre-cooling application
I. Technical Principles and Operating Methods
Chiller
A refrigeration system is used to generate constant-temperature chilled water (usually 5-10℃), which is directly injected into the concrete mixing process or circulated to the aggregate pre-cooling system. Heat exchange between the chilled water and concrete materials lowers the overall temperature.
Supports a large temperature difference direct cooling mode, meeting the high-efficiency cooling needs of concrete mixing water, especially suitable for mixing plants requiring continuous water supply.
Ice Maker (Flake Ice Machine/Block Ice Machine)
Ice (such as flake ice or block ice) is made using a refrigerant compression cycle system. Flake ice or crushed ice is directly added to the concrete, and the melting of the ice absorbs the heat of the hydration reaction.
Because of its large contact area and controllable melting speed, flake ice can precisely adjust the concrete cooling rate, with a cooling range of 6-11℃.
II. Application Scenarios and Engineering Requirements
Chiller Application Scenarios
Stable cooling requirements: such as municipal engineering, high-rise building foundations, and other scenarios requiring long-term stable cooling.
Aggregate pre-cooling: Coarse aggregates are sprayed or washed with chilled water to lower the initial temperature of the concrete (for every 1℃ decrease in aggregate temperature, the overall concrete temperature decreases by approximately 0.5℃).
Ice Maker Application Scenarios
High-temperature environment construction: In summer or tropical regions, it is necessary to quickly offset the impact of high ambient temperatures on concrete.
Large-volume concrete engineering: such as hydropower dams, nuclear power plants, and other structures requiring high-intensity temperature control, using the ice-water mixing method to achieve deep cooling.
III. Comparison of Core Advantages
Equipment Type Advantages Source
Chiller
① Continuous and stable cooling, suitable for automated mixing plants;
② Low energy consumption, suitable for large-scale cooling needs;
③ Long equipment life (12-15 years), low maintenance cost.
Ice Maker
① Fast cooling speed (high heat absorption efficiency of ice melting);
② Flexible control of ice addition, adaptable to dynamic construction needs;
③ Can be used in combination with other cooling measures (such as chilled water systems).
IV. Comprehensive Application Cases
Combined Chiller and Ice Maker Solution
In concrete mixing plants, chillers are used to pre-cool mixing water and aggregates, and ice makers provide supplementary ice flakes to achieve multi-stage cooling (such as a commercial complex project in Shanghai).
Extreme Environment Applications
In tropical regions, containerized ice makers and chiller units operate together to ensure that the concrete discharge temperature is ≤25℃, meeting the construction requirements of high-grade concrete.
V. Precautions
Energy balance: Chillers have lower energy consumption during long-term operation, while ice makers need to optimize refrigeration power according to ice production needs.
Ice-water ratio: When using ice to replace mixing water, accurate weighing is required to avoid affecting the concrete mix ratio.
Ice makers and chillers, through complementary technologies, have become core equipment for modern concrete temperature control, significantly improving structural durability and construction efficiency, especially in large-volume, high-precision projects.
