Chilled Water Units are divided into water-cooled and air-cooled types. The water-cooled chilled water unit is an industrial cooling equipment equipped with a compressible refrigeration circuit, using water as the cooling medium for the condenser and water as the refrigerant. It is commonly referred to as a water-cooled ice water unit or water-cooled frozen water unit. It features a scroll compressor and shell-and-tube condenser, offering high energy efficiency, low cost, and significant cooling capacity. The air-cooled chilled water unit is also equipped with a compressible refrigeration circuit, using air as the cooling medium for the condenser and water as the refrigerant. It is typically called an air-cooled ice water unit or air-cooled frozen water unit. It utilizes a scroll compressor and finned condenser, providing compact size, ease of mobility, and the ability to be installed and used without a cooling water tower.
Chiller specifications:
Compressors: Equipped with high-quality scroll compressors from the U.S. or Danfoss from Denmark, ensuring safety, quiet operation, energy-saving, and durability.
Condenser: Utilizes an upward-blowing cooling system with double-sided air intake, offering excellent condensation performance.
Evaporator: Utilizes a high-efficiency, reinforced copper tube design with coil (shell-and-tube option), capable of rapidly evaporating refrigerant to produce low-temperature chilled water.
Ice Water Pump: High flow rate ice water pump, operates smoothly, no leakage, low noise
Control System: Utilizes electrical components from Schneider and other brands, along with brand-name microcomputer control systems, featuring remote control capabilities and alarm information output.
Innovative Design: Unique appearance, sturdy structure, stable center of gravity, leak-proof, ensuring dry factory floors.
Thermal Constant Feature: Temperature control within ±1°C, explosion-proof device included
Chiller operating principle:
The operation of the chilled water system is through three interrelated systems: the refrigerant circulation system, the water circulation system, and the electrical self-control system.
The refrigerant absorbs heat from the cooled object and vaporizes into steam within the evaporator. The compressor continuously extracts the generated steam from the evaporator, compresses it, and the high-pressure, high-temperature steam is then sent to the condenser where it releases heat to the cooling medium (such as water or air) and condenses into a high-pressure liquid. After passing through a throttling device to reduce pressure, it enters the evaporator again, vaporizes, absorbs heat from the cooled object, and the cycle repeats.
