6 Key Parameters to Consider When Selecting a Chiller Unit

In industrial refrigeration and central cooling systems, the selection of chiller units directly affects system energy efficiency, operational stability, and long-term operating costs. For industries such as food processing, ice making, chemical and industrial cooling, scientific and reasonable selection of chiller units is particularly important. This article will start from practical applications and provide a detailed introduction to the six key parameters for selecting industrial chiller units, combined with FOCUSUN‘s engineering experience, to help users make the right choices.

1. Cooling Capacity

The refrigeration capacity is the most critical parameter in the selection of chiller units, usually expressed in kW, RT, or kcal/h. Insufficient cooling capacity can lead to long-term full load operation of the system, affecting the lifespan of the equipment; Excessive cooling capacity can result in energy waste.

During the project design phase, FOCUSUN will accurately calculate the required cooling capacity based on the customer’s process requirements, environmental temperature, and load changes to avoid selection deviations.

2. Outlet temperature and return temperature

The chiller unit needs to determine the outlet temperature and return temperature according to the actual process requirements. Different temperature differences will directly affect the configuration and energy efficiency performance of the unit.

FOCUSUN chillers can be customized according to different application scenarios to ensure stable operation of the system within the target temperature range.

3. Cooling method (air-cooled/water-cooled)

Cooling method is one of the important parameters for selecting chiller units:

Air cooled chiller unit: easy to install, suitable for areas with limited water resources

Water cooled chiller unit: high energy efficiency, suitable for large-scale industrial projects

FOCUSUN can recommend the most suitable cooling method for customers based on the project site conditions.

4. Compressor type and brand

The compressor is the core component of the chiller unit, and its performance directly determines the system stability and service life.

FOCUSUN adopts internationally renowned compressor brands and supports specifying brands and models according to customer requirements to ensure efficient operation of chiller units under different working conditions.

5. Power and voltage parameters

The power standards vary greatly among different countries and regions, so it is necessary to clarify the voltage, frequency, and number of phases when selecting a chiller unit.

FOCUSUN chillers support multiple power configurations to meet the usage needs of different markets worldwide.

6. Energy efficiency ratio and operating costs

In addition to initial procurement costs, long-term operating costs are equally important. High energy efficiency chillers can significantly reduce electricity bills.

FOCUSUN fully considers energy efficiency optimization in its design, helping customers achieve energy conservation and consumption reduction while ensuring refrigeration efficiency.

Conclusion: Choosing FOCUSUN brings peace of mind

The selection of chiller units involves multiple technical parameters, and improper consideration of any one link may affect the overall performance of the system. Based on rich project experience, FOCUSUN can provide customers with professional chiller selection solutions to ensure efficient, stable, and long-term operation of the equipment.
