How to achieve low cost operation of screw chiller

Jun 05, 2023

In this era of advocating energy saving and environmental protection, it is very necessary to reduce the operating cost of the screw chiller. We can start from the product itself, and pay attention to various details in daily use, so as to reduce energy consumption and reduce the operating cost of the screw chiller. To reduce the operating cost of the screw chiller, we must start from its energy consumption. The energy consumption of the screw chiller mainly depends on whether the unit is faulty, and the other is the operating power of the unit. Next, let's talk about how to reduce the operating cost of the screw machine from several aspects.

water cooled screw chiller cost

1) Regular maintenance: Regular maintenance of the screw chiller is essential to ensure efficient operation. This includes cleaning the evaporator and condenser coils, checking and maintaining refrigerant levels, lubricating the compressor, and replacing worn out components.

2) Optimize water flows: Adjusting the flow rates of the chilled and condenser water can significantly impact the energy consumed. By minimizing the flow rates, the chiller consumes less energy.

3) Control temperature set points: Ensure optimal set points for both condensing and evaporator temperatures to prevent unnecessary operation of the chiller.

4) Use economizer mode: Many screw chillers have an economizer mode that utilizes free cooling when the outside temperature is cooler. This mode helps save energy and reduces running costs.

5) Upgrade to an energy-efficient system: Consider upgrading to a more efficient screw chiller model to reduce running costs. The initial investment may be higher, but it will pay off in terms of reduced energy consumption and lower operating costs.

6) Utilize VFDs: Variable Frequency Drives (VFDs) allow the chiller to operate at varying speeds, depending on the cooling requirement. This results in less energy consumed, along with reduced wear and tear on the equipment.

7) Use high-efficiency motors: The installation of high efficiency motors can significantly reduce energy consumption. These motors have high power factors, which means they consume less energy while operating at the same load.

8) Monitor energy usage: Regular energy monitoring helps identify inefficiencies and areas for improvement. By tracking energy usage, property owners can determine the best practices for reducing operating costs.
