Product Description

Water cooled chiller is an efficient refrigeration equipment, widely used in commercial buildings, industrial facilities and data centers and other places. It is dissipated by water cooling, with strong cooling capacity, stable operation, energy saving and environmental protection.

Structure and working principle

● Core structure

● Compressor (screw/centrifugal type): it drives refrigerant circulation and provides refrigeration power.

● Condenser: Cooling water exchanges heat with high-temperature refrigerant, and heat is discharged through the cooling tower.

● Evaporator: The refrigerant evaporates to absorb the heat of frozen water and output low-temperature frozen water.

● Throttle device (expansion valve): control refrigerant flow and adjust evaporation pressure.

● Double circulation system: cooling water circulation (heat dissipation) is separated from chilled water circulation (cooling supply).

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

● High efficiency and stability: high efficiency of water cooling and heat dissipation, and COP value (energy efficiency ratio) can reach above 5.0.

● Low noise: The main noise source (cooling tower) can be installed far away from the building.

● Long life: the design life of core components is 15-20 years, and the maintenance cost is low.

Application scenario

● Industry: reactor cooling in chemical plant, heat dissipation in data center server.

● Business: central air conditioning system in large shopping malls and hotels.

● Special environment: high temperature area (such as Middle East), confined space (underground computer room).

FAQ

Q1: How to deal with scaling in cooling water system?

A: Regular chemical water treatment+automatic blowdown device to prevent scale from blocking the pipeline.

Q2: How to prevent freezing in winter?

A: Add antifreeze (ethylene glycol) or keep water circulating to avoid freezing when shutdown at low temperature.
