What does chilled water do for concrete?
After pouring, the concrete surface must be kept moist. Regularly spraying cold water on the surface will lower the concrete's temperature via evaporative cooling and allow for even setting of the material. Adding water, however, must be done in a controlled way.
Provide cold water for mixing concrete, make the molecular structure of the mixed soil suitable for construction road requirements, and effectively enhance the temperature and temperature of the mixed soil.
Application Description:
For concrete applications, your thermal load capacity needs to be the single most determining factor in your chiller buying decision. Air cooled chillers are normally installed for concrete cooling applications because of their ease of installation. Sometimes WPI installs FRP Whaley cooling towers if the required temperatures are above 70degF. Water cooled chillers can be installed as well with a cooling tower removing the heat from the water cooled condenser.
Chiller Capacity is effected by several factors:
Incoming uncooled water temperature:
The warmer your water feed, the fewer yards you can cool with your chiller system.
Ambient Temperature
High ambients lower the chiller’s capacity and make it less efficient. You should always size your chiller based on maximum summer high temperature. If it seldom reaches 100F, but usually stays around 80F, then you could be safe going with a 90degF factor.
Added batch water amount
The larger the volume of the water batch you mix to each concrete yard, the less yards worth of cooled batch water that the process can produce per day.
Blended chilled water
If you use part chilled water, and part unchilled water in your batch process when your current capacity requirement drops below 100%needed, you can save money on operating costs, most notibly energy. A modular chiller system would be ideal in this situation becuase you could stage in modules as needed per the load requirement. You could have 2nd, 3rd, and 4th units sitting and waiting to be used, saving money all the while. However, when load increases back up to 100%, the 2nd, 3rd, and 4th units kick on automatically to accommodate.
Other Chilled water loads
Some concrete companies use their chilled water loop for multiple purposes(wash out or pre-cooling mixer), then this will reduce the chiller’s daily capacity.
System heat leak
You will gain heat in the system through the batch tank walls, the circulation and supply pumps, and the circulating lines. Most chiller sizing professionals recommend sizing chillers for 20% over theoretical load size to make up for this additional heat gain.
Anyda Chiller is consistently working over and successfully manufactured a full stock of Concrete Chiller, available in different cooling capacities for worldwide supply with customization services for clients.
Anyda Chiller designed Concrete Chiller is made of fin condenser, scroll or screw compressor, evaporator, plate and frame heat exchanger, evaporator, water tank, condenser coils, screen display, protection system, power supply, and PLC-based temperature control.
Concrete Chiller has different benefits for different construction materials as given below.
The process of creating concrete requires highly accurate and precise temperature and chilled water for concrete mixing inside a tank, maintained by the use of a Concrete Chiller featured by PLC temperature controller and chilled water batch-wise supply ensuring concrete processing.
Concrete Chiller is highly efficient in cooling production configured by the installation of branded heat exchanger with double-sided exchanger tubes enforcing quick heat exchange from concrete tank to unit chilled water.
Concrete Chiller is featured with power-saving water/air-cooled condenser that has a high capacity to collect temperature from the concrete tank and dissipate it by consuming lower power supply when chilled water requirements will be 16000kg/hour.
Modular type Concrete Chiller deals with elevated temperature during concrete processing batch-wise by releasing heat efficiently from batch tanks with screen display.
Anyda brand Concrete Chiller is equipped with a smoothly rotating compressor that applies pressure for fluent chilled water circulation preventing noise production and ensuring quiet operation.
Concrete Chiller ensures the proper mixing of sand, cement, and water inside the tank by regulating temperature during mixing and then cooling the concrete mixture with high-pressure flow ensuring concrete curing.
Anyda Chiller manufactured Concrete Chiller has numerous applications for different construction instruments:
The construction industry, cement processing industry, dams, buildings, and road manufacturing machines cooling, etc.
