Project background

The large-scale pouring of large hydro power dams, nuclear power plants, high-speed railways and high-rise building foundations requires the use of temperature-controlled concrete. In the process of concrete mixing, the internal volume of concrete hydration heat increases, especially in the high temperature working conditions for mixing generated heat is higher, in the later curing or low temperature, due to thermal expansion cold contraction will lead to the internal volume of concrete decrease, this process will usually appear cracks. Therefore, the initial pouring temperature of concrete should be low to reach the limited temperature of the building design unit, so as to achieve the quality of the project. Construction will use cold water for concrete cooling.

In order to meet the needs of such customers in engineering, the cooling industrial chiller of concrete mixing plant directly provides 0-10℃ chilled water, or 0-2℃ ice water mixture, which is widely used in high-speed railway, tunnel, dams, hydropower station and other civil concrete mixing cooling.

Solutions

There are generally two kinds of high efficiency concrete mixing plant water cooling system solutions:

1, Batching plant water chiller + cooling tower

2.Integrated water cooling system

concrete mixing plant special water cooling machine adopts famous brand screw compressor for refrigeration host, combined with the automatic control system, according to the operation mode of in and out of the water temperature or summer cooling automatically choose a cooling or more sections, has the characteristics of energy saving, time saving, stability, environmental protection, than traditional concrete cooling chiller ice machine (group) energy saving 10-35%, At the same time, the cost of investment is greatly reduced.
