What is a water-cooled compressor?

Water-cooled compressor is a kind of compressor cooling method which takes away the heat generated when the compressor works by circulating cooling water. It is one of the common and efficient cooling schemes in the industrial field (especially in large and medium-sized high-load applications).

The core principle of water-cooled compressor is that in the process of compressing gas (such as air, refrigerant, etc.), the friction of mechanical parts and the compression of gas itself will produce a lot of heat energy. The core of water cooling system is to use water to flow through the heat exchanger inside or outside the compressor (such as cylinder liner, intercooler and aftercooling)

Device), absorb heat and take it away, so as to maintain the compressor running in a safe and efficient temperature range.

Core special requirements include:

High cooling efficiency: water has large specific heat capacity and good thermal conductivity, and the cooling effect is far better than that of air cooling, especially suitable for high power, high exhaust temperature and continuous operation.

Stable operation: little affected by ambient temperature, and can keep good cooling in high temperature or closed environment.

Low noise: no large high-speed fan is needed, and the running noise is relatively low.

Compact equipment layout: the compressor body does not need a huge fin radiator, saving space.

Low exhaust temperature: it can cool compressed gas more effectively and improve the quality of gas production and the safety of downstream equipment.

Water-cooled compressor is a type of compressor with efficient thermal management through water circulation. Because of its excellent cooling performance, stability and adaptability to harsh environment, it has become the first choice for large-scale industrial applications. However, its high complexity, initial investment and requirements for water system maintenance mean that it is usually only in the wind.

The cold mode will be selected only when it can't meet the heat dissipation requirements. Choosing water cooling or air cooling requires comprehensive consideration of power, operation system, environmental conditions, water resources and total holding cost.
