    Circulating Water Cooling

    Overview Knowledge Standards Terms
    Circulating water cooling involves pumping water through heat-generating equipment to absorb heat, and then dissipating the heat via a cooling tower or heat exchanger before recirculating the water, thereby cooling the equipment. It is used in applications requiring continuous heat dissipation, such as laboratory instruments and injection molding machines.
    Selection
    Determine the cooling capacity based on the equipment's heat dissipation, and match the pump's flow rate and head. Select corrosion-resistant materials according to water quality, and choose between an open or closed system based on the available space. Verify power compatibility and ensure maintenance access is reserved.

    The Impact of Cooling Circulating Water Chillers on the Temperature Stability of Digesters
    The cooling circulator helps maintain a stable temperature for the digester by circulating the cooling medium, thereby improving the repeatability of experiments. Its working principle involves using a refrigeration system to lower the water temperature, and then circulating the cooled water to the digester through a circulation pump to absorb excess heat.
