THE ROLE OF CHILLERS IN PLASTIC PRODUCTION

Chillers provide stable chilled water to cool molds, injection machines, and auxiliary equipment in the plastic production line. Precisely controlled water temperature helps shorten the injection cycle while ensuring the surface gloss and dimensional accuracy of finished products.

A high-performance chiller system allows manufacturers to maintain stable productivity, reduce defective products, and extend equipment lifespan. Conversely, if the chiller consumes excessive power or delivers insufficient cooling, it can significantly increase operating costs and disrupt production schedules.

FACTORS AFFECTING CHILLER POWER CONSUMPTION

To understand why some chillers are more energy-efficient than others, it’s essential to consider key technical factors directly influencing energy performance:

• Compressor efficiency: The compressor is the “heart” of a chiller system. The higher its compression efficiency, the less power is required to achieve the same cooling capacity.
• Control technology (Inverter/DC Inverter): Conventional chillers operate in on/off mode at full load, wasting power during low-load periods. In contrast, inverter technology allows the compressor to adjust its capacity according to actual demand, greatly reducing energy consumption.
• Cooling method: Water-cooled chillers usually offer a higher Coefficient of Performance (COP) than air-cooled chillers, though they require cooling towers and circulation pumps. Selecting the right cooling method helps balance investment costs and energy efficiency.
• Chilled water system design: Proper piping layout, insulation, and heat exchanger arrangement reduce thermal loss and pressure drop, optimizing overall system efficiency.

From these factors, it’s clear that choosing a DC Inverter chiller is the key solution for saving electricity in modern plastic manufacturing.

ENERGY-SAVING SOLUTIONS FOR PLASTIC FACTORIES

Below are practical approaches factories can apply to improve energy efficiency:

• Optimize chiller capacity based on actual load: Avoid selecting oversized chillers, as they often operate at low load, resulting in unnecessary power waste.
• Adopt DC Inverter technology: DC Inverter chillers can adjust compressor speed dynamically, saving 30–40% of electricity compared to conventional on/off chillers.
• Perform regular maintenance: Cleaning condensers and evaporators, checking refrigerant levels, circulation pumps, and water pressure ensures the system operates at peak performance.
• Design piping systems efficiently: Minimize pipe length and bends to reduce pressure loss and heat leakage.
• Apply smart control systems: Real-time monitoring of temperature and energy usage via PLC or BMS helps detect abnormal consumption and make timely adjustments.

These improvements not only reduce electricity costs but also extend equipment lifespan and maintain consistent product quality.
