Chilled Water Units are categorized into water-cooled and air-cooled types. The water-cooled chilled water unit is an industrial cooling equipment equipped with a reciprocating refrigeration circuit, using water as the condenser medium and as the refrigerant carrier. It is commonly referred to as water-cooled chilled 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.
An air-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 also commonly referred to as an air-cooled ice water chiller or air-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 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 unit with double-sided air intake for excellent condensation efficiency.
Evaporator: Equipped with a high-efficiency, reinforced copper tube design in coil form (shell-and-tube option available), capable of rapidly evaporating the refrigerant to produce low-temperature chilled water.
Ice Water Pump: High-flow ice water pump with smooth operation, no leakage, and low noise
Control System: Utilizes electrical components from Schneider and other brands, along with branded 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 Control Feature: Capable of maintaining temperature within ±1°C; explosion-proof device
Operation Principle of the Cold Water Machine:
The operation of the chilled water system is through three interconnected systems: the refrigerant circulation system, the water circulation system, and the electrical automatic control system.
The refrigerant (i.e., the cooling agent) absorbs the heat of 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 the heat of the cooled object, and the cycle repeats.
