For large-scale construction projects such as hydroelectric dams, nuclear power plants, high-speed railways, and high-rise buildings, temperature-controlled concrete is critical to ensure the structural integrity of the final product. During the mixing of concrete, the internal heat of hydration increases, especially under high temperatures. This excessive heat can cause thermal expansion during the curing phase, leading to cracks and reducing the quality of the concrete. To mitigate this, the initial pouring temperature of the concrete must be kept low, ideally reaching the specified temperature limits outlined in the architectural design.



This is where concrete cooling chillers come into play. By utilizing cold water during the construction process, the heat of hydration is effectively reduced, ensuring that concrete maintains optimal temperature throughout the curing process.



Reducing Concrete Temperature with Industrial Chillers

One of the most effective ways to control the temperature of concrete is by lowering its pouring temperature using industrial cooling systems. Industrial chillers can produce low-temperature water, typically below 20°C, to keep concrete at the ideal temperature range for curing. This process is particularly important during summer months when high ambient temperatures make it difficult to maintain a controlled water temperature for mixing.

The temperature control range of 0-10°C allows for precise management of the cooling process, ensuring that thick concrete structures—such as those used in dams, bridges, power stations, and tunnels—do not suffer from thermal expansion and cracking. The result is better-quality concrete with improved strength and durability.



Key Components of the Cooling System

A well-designed refrigeration system for concrete cooling consists of several essential components:



Compressor: The core of the refrigeration system, responsible for compressing the refrigerant and converting electrical energy into mechanical energy to drive the cooling process.

Evaporator: This component absorbs heat by evaporating the refrigerant, which cools the circulating water used for concrete cooling.

Condenser: The condenser releases the heat absorbed by the refrigerant, transforming the refrigerant from gas back into a liquid.

Thermal Expansion Valve: This valve controls the flow of refrigerant into the evaporator, ensuring that the temperature and pressure remain consistent for optimal cooling performance.

Filter Drier: It prevents moisture and contaminants from entering the system, ensuring that the refrigerant remains clean and the system operates efficiently.

Liquid Receiver: This stores the refrigerant liquid after it leaves the condenser and helps regulate the refrigerant flow when the cooling demand changes.

The refrigerant typically used in these systems is R407C or R404A, known for their efficient heat transfer properties and environmental friendliness.
