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 the water-cooled ice water unit or water-cooled frozen water unit. It employs 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 generally known as the air-cooled ice water unit or air-cooled frozen water unit. It utilizes a scroll compressor and finned condenser, featuring compact size, ease of 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 efficiency.
Evaporator: Equipped with a high-efficiency copper tube design featuring a coil type (optional shell and tube type), capable of rapidly evaporating refrigerant to produce low-temperature chilled water.
Ice Water Pump: High-flow ice water pump with smooth operation, leak-free, and low noise.
Control System: Utilizes Schneider and other electrical components, along with brand-name microcomputer control systems, capable of remote control and alarm information output.
Innovative Design: Unique appearance, sturdy structure, stable center of gravity, leak-proof, ensuring a dry factory floor.
Thermal control feature: capable of maintaining temperature within ±1°C, equipped with explosion-proof devices.
Chiller operating principle:
The operation of the cold water machine system is through three interrelated systems: the refrigerant circulation system, the water circulation system, and the electrical automatic 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 and compresses it. 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.
