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 water as the refrigerant. It is commonly referred to as a 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 reciprocating refrigeration circuit, utilizing air as the condenser medium and water as the refrigerant. It is generally known as an Air-Cooled Ice Water Unit or Air-Cooled Frozen Water Unit. It uses 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: High-quality scroll compressors from USA Genuair 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 in coil form (optional shell-and-tube form), capable of quickly evaporating the refrigerant to produce low-temperature chilled water.
Ice Water Pump: High flow ice water pump, operates smoothly, no leakage, low noise
Control System: Equipped with electrical components from Schneider and other brands, and 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, ensuring a dry factory floor.
Constant Temperature Feature: Capable of maintaining a temperature control within ±1°C, featuring explosion-proof devices.
Operation Principle of Chiller:
The operation of the chill water system is through three interrelated systems: the refrigerant circulation system, the water circulation system, and the electrical automatic control system.
The refrigerant (i.e., refrigerating agent) 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, air, etc.) 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.
