Screw chiller vs centrifugal chiller
Screw chiller uses screw compressor, mainly through the combination of two rotating screws, when the screw rotates the shape can be gradually compressed gas, increase the pressure and temperature of the gas, so as to achieve refrigeration effect, more suitable for applying to the high load operation.
Centrifugal chiller uses centrifugal compressor, centrifugal compressor is through the centrifugal force of the gas compression, produce refrigeration effect, more suitable for large flow and variable speed operation.
Screw chiller vs centrifugal chiller pros and cons
● Stability: Screw chillers provide stable cooling effect during long working hours and are suitable for industries and scenarios with long hours of continuous work.
● Low vibration and low noise: the unique design of the screw compressor allows the equipment to maintain low vibration and low noise during operation.
● Adjustability: Screw chillers can automatically adjust the operating parameters according to the actual load demand, as a way to provide higher energy efficiency and temperature control.
● Larger size: Screw chillers are typically larger in size and may require more installation space for applications where space is limited or small.
● Need for specialized maintenance: Screw chillers require specialized skills for post maintenance, such as regular inspection and cleaning, compressor maintenance, etc., which may require additional labor costs and technical support.
● High reliability: Centrifugal chillers utilize centrifugal compressors, which have fewer moving parts and therefore have a relatively low failure rate.
● Easy maintenance: Centrifugal chillers are relatively easy to maintain and usually require less maintenance work and simple maintenance procedures.
● Lower cost: Centrifugal chillers typically have a lower initial investment cost and are less expensive to design and manufacture than other types of chillers.
● Higher noise levels: Centrifugal chillers typically produce higher noise levels, so additional noise control measures may be required.
● Higher power start-up: Centrifugal chillers may require higher power consumption during start-up and therefore may cause a momentary shock to the electrical circuits, which requires proper power provision and management.
Screw chiller vs centrifugal chiller price and cost
The price of a screw chiller and a centrifugal chiller depends on a number of factors, usually including model, energy consumption, customization and other factors; for example, the power and capacity of the equipment, the price of a larger capacity will also be higher, because it will require a larger compressor and other equipment to handle a larger load; therefore, you need to consult with the different chiller manufacturers according to the application industry and specific requirements.
Of course, in addition to the above comprehensive factors, the price of Screw chillers is usually slightly higher than centrifugal chillers, first of all, the design and manufacture of screw chillers to be more complex, can cover more industries and scenarios, have better cooling capacity, so it will make its price is high. And screw chiller and centrifugal chiller market demand has a more obvious differentiation, according to the global users in Google's search data research results, screw chiller market demand is much larger than the centrifugal chiller.
