Product Description

Water-cooled screw chiller is a kind of refrigeration equipment based on screw compressor, which is mainly used for industrial and commercial refrigeration needs. Its core components include screw compressor, shell-and-tube condenser, shell-and-tube evaporator, thermal expansion valve, drying filter and electrical control part.

Structure and working principle

● Cooling tower: heat dissipation core, which discharges heat through water evaporation/air convection.

● Water pump: to drive cooling water and chilled water circulation, it is necessary to match the system resistance.

● Intelligent control: PLC automatically adjusts the load to realize energy-saving operation.

● Modular unit: multiple units are connected in parallel, which can flexibly match the load change.

● Heat recovery module: hot water is produced by condensing waste heat, and the comprehensive energy efficiency is improved by 20%.

Working principle

● The refrigerant is driven by the compressor to complete the cycle of "compression → condensation → throttling → evaporation", the cooling water takes away the condensation heat, and the chilled water delivers the cold energy to the terminal equipment (such as fan coil units).

Product advantage and Uses

Product advantages and characteristics

● Save energy and money: save 30% electricity compared with air-cooled units, and the long-term operation cost is lower.

● Space-friendly: the main engine can be placed in the basement, saving the exterior space of the building.

● Environmental compliance: Support R32/R134a and other low GWP refrigerants, and comply with global environmental regulations.

Application scenario

● High-load scenario: 24-hour constant temperature in hospital operating room and clean cooling in semiconductor workshop.

● Renovation of old buildings: no need for external platform, suitable for renovation projects with limited space.
