Screw type of chiller has air cooled screw chiller and water cooled screw chiller 2 types. Both two type adopts screw type compressor, the unit by the evaporator out of the state of the gas refrigerant adiabatic compression of the compressor, into the high temperature and high pressure state.After being compressed, the gas refrigerant, in the condenser, isobaric cooling condensation, after condensation change into liquid refrigerant, and then through the throttle valve expansion to low pressure, into a mixture of gas and liquid.Among them, the liquid refrigerant at low temperature and low pressure absorbs the heat of the cooled substance in the evaporator and turns into the gaseous refrigerant again.The gaseous refrigerant re-enters the compressor through the pipeline and starts a new cycle.These are the four processes of the refrigeration cycle and the main principle of the screw chiller.

Product introduction
What is an Air-Cooled Chiller?
An air-cooled chiller is an industrial refrigeration unit that uses air as its heat dissipation medium. Its core function relies on forced convection via fans to cool the condenser, eliminating the need for cooling towers or water pumps. This design ensures straightforward installation and maintenance.
I. Core Working Principle
Based on the vapor compression refrigeration cycle, heat transfer is achieved through four core components:
Evaporator: The refrigerant absorbs heat from the circulating water, evaporating into a low-temperature, low-pressure gas while producing chilled water.
Compressor: Compresses the gaseous refrigerant into a high-temperature, high-pressure gas.
Condenser (Finned Type): Forced airflow from fans carries away the refrigerant's heat, condensing it into a high-pressure liquid.
Expansion Valve: Throttles and reduces pressure, returning the refrigerant to a low-temperature, low-pressure state before it recirculates to the evaporator.
II. Key Features
Easy Installation: Integrated design requires only power and process water connections, eliminating need for cooling towers, pumps, or auxiliary piping.
Water-Saving & Eco-Friendly: No cooling water consumption, ideal for water-scarce or poor-water-quality regions.
Low Maintenance: Primarily involves periodic cleaning of condenser fins and filters, resulting in minimal upkeep costs.
Significant Environmental Impact: Heat dissipation efficiency is highly temperature-dependent; cooling capacity decreases in high-temperature environments.
Application Scope: Primarily for small to medium cooling capacities, suitable for compact systems and mobile/temporary scenarios.
III. Typical Applications
Industrial Equipment Cooling: Plastic injection molding, laser processing, electronics manufacturing, electroplating, printing, food processing, etc.
Commercial/Small-Scale Air Conditioning: Retail stores, offices, small data centers, laboratories, etc.
Mobile/Temporary Scenarios: Outdoor construction sites, exhibitions, emergency cooling, etc.
8-Hour Pre-Shipment Testing
Every water-cooled chiller undergoes continuous 8-hour full-load operation testing before shipment. This comprehensive evaluation covers refrigeration performance, temperature accuracy, operational noise, electrical safety, and system pressure.
Only after passing these comprehensive, rigorous tests and confirming no abnormalities will the unit be packaged for shipment. This ensures the equipment is ready for immediate installation and use upon arrival at the site, delivering long-term stable operation for worry-free and hassle-free customer use.
