Water chillers are divided into water-cooled and air-cooled types. A water-cooled chiller is an industrial cooling equipment equipped with a reciprocating refrigeration cycle, using water as the cooling medium in the condenser. It is typically also referred to as a water-cooled ice water chiller or water-cooled freezing water chiller. It utilizes a scroll compressor and shell-and-tube condenser, featuring high energy efficiency, low cost, and considerable cooling capacity. Air-cooled chillers are also equipped with a reciprocating refrigeration cycle, using air as the cooling medium in the condenser and water as the refrigerant. They are commonly called air-cooled ice water chillers or air-cooled freezing water chillers. They come with a scroll compressor and finned condenser, offering compact size, ease of mobility, and the convenience of installation without a cooling water tower.
Chiller configuration:
Compressors: Utilizing high-quality scroll compressors from USA GEA or Danish Danfoss, safe, quiet, energy-saving, and durable.
Condenser: Utilizes an upward-blowing cooling system with double-sided air intake, offering excellent condensation efficiency.
Evaporator: Utilizes a highly efficient coil design (optional shell and tube design) for rapid refrigerant evaporation, producing low-temperature chilled water
Ice Water Pump: Utilizes a high-flow 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, enabling remote control and alarm information output.
Innovative Design: Unique appearance, sturdy structure, stable center of gravity, leak-proof, ensuring a dry floor in the factory.
Thermal Control Feature: Capable of maintaining a temperature within ±1°C, with explosion-proof equipment.
Chiller operating principle:
The operation of the chilled water system is through three interrelated systems: the refrigerant circulation system, the water circulation system, and the electrical self-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 high-pressure liquid. After passing through a throttle device to reduce pressure, it enters the evaporator again, vaporizes, absorbs the heat of the cooled object, and this cycle repeats indefinitely.
