Chilled water units are categorized into water-cooled and air-cooled types. A water-cooled chilled water unit is an industrial cooling equipment equipped with a compressor 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. Featuring a scroll compressor and shell-and-tube condenser, it boasts high energy efficiency, low cost, and large cooling capacity.
A wind-cooled chiller is an industrial cooling equipment equipped with a compressor refrigeration circuit, using air as the condenser medium and water as the refrigerant. It is commonly referred to as a wind-cooled ice water chiller or wind-cooled frozen water chiller. It features a scroll compressor and finned condenser, offering compact size, easy mobility, and the ability to be installed and used without a cooling water tower.
Chiller configuration:
Compressors: Utilizing high-quality scroll compressors from USA GEA or Danish Danfoss, 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: Equipped with a high-efficiency copper tube design in coil form (optional shell-and-tube form), capable of rapidly evaporating the 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, capable of remote control and alarm information output.
Innovative Design: Stylish appearance, sturdy structure, stable center of gravity, leak-proof, keeping the factory floor dry at all times.
Thermal Constant Feature: Temperature control within ±1°C, explosion-proof device included
Chiller operation principle:
The operation of the cold water machine system is through three interconnected 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 and compresses the produced steam from the evaporator. After compression, the high-temperature, high-pressure steam is sent to the condenser, where it releases heat to the cooling medium (such as water or air) and condenses into high-pressure liquid. The liquid then passes through a throttle device to reduce pressure and enters the evaporator again, vaporizing once more and absorbing heat from the cooled object. This cycle repeats indefinitely.
