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 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. 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 compressor refrigeration circuit, using air as the cooling medium for the condenser and water as the refrigerant. It is generally known as an Air-Cooled Ice Water Unit or Air-Cooled Frozen Water Unit. It features a compact design, ease of mobility, and can be installed and used without a cooling water tower, utilizing a scroll compressor and finned condenser.

Innovative Design: Stylish appearance, sturdy structure, stable center of gravity, leak-proof, ensuring a dry factory floor.
Thermal Control Feature: Temperature can be maintained within ±1°C; explosion-proof device incorporated
Operating 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 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 throttle device to reduce pressure, it enters the evaporator again, vaporizes once more, absorbs heat from the cooled object, and the cycle repeats.
