The screw-type water-cooled chiller unit is an efficient and stable refrigeration equipment, widely used in central air conditioning systems for industrial, commercial, and large-scale public buildings. It uses a screw compressor to drive the refrigerant cycle and water as the cooling medium to achieve heat transfer and discharge. The screw compressor has become the core component of the chiller unit due to its simple structure, stable operation, and easy maintenance.
Through the rotational movement of the screw compressor, the screw-type water-cooled chiller unit compresses low-temperature and low-pressure refrigerant gas into high-temperature and high-pressure gas. Subsequently, the refrigerant exchanges heat with water in the condenser, condensing into a liquid. After being throttled by the expansion valve, it enters the evaporator, absorbs heat, and evaporates into gas, thus completing the refrigeration cycle.
It is suitable for places that require large cooling capacity and long-term operation, such as large shopping malls, hospitals, data centers, and factories. Its high efficiency and energy-saving characteristics make it particularly popular in energy-intensive industries.
Ensure the unit is installed in a well-ventilated environment without corrosive gases, and avoid direct sunlight.
Cooling water must undergo softening treatment to prevent scaling and corrosion. It is recommended that the water hardness be controlled at ≤150mg/L.
The outlet temperature of chilled water is usually set at 7-12℃, and the inlet temperature of cooling water is recommended to be controlled at 25-32℃.
Regularly clean the condenser and evaporator, and check the refrigerant charge to ensure the unit operates efficiently.
It usually needs to be equipped with cooling towers, water pumps, water treatment equipment, etc., to form a complete refrigeration system.
- Adopting advanced structural design and reasonable system matching, the unit boasts high energy efficiency ratio and a compact size.
- It supports variable capacity adjustment and flexible start-stop, ensuring comfort and energy conservation.
- Equipped with a large touch screen, it features powerful control functions, including fault self-diagnosis and other multiple functions.
- Multiple safety protection measures are in place to ensure safe and reliable operation of the unit.
- Applicable Area: Over 1000 m²
