What is Ice Thermal Storage Screw Chiller

LG Ice Thermal Storage Screw Chiller shown in a virtual space with four key features summarized. LG Ice Thermal Storage Screw Chiller shown in a virtual space with four key features summarized.

Ice Thermal Storage Screw Chiller

It operates by freezing and storing ice in a tank overnight. During the day, the stored ice is melted to provide cooling. By utilizing electricity during off-peak night time hours, it helps reduce operating costs while delivering efficient cooling.

The Optimal and Flexible Solutions

LG Screw Chiller provides various utilizing options such as ice thermal storage. These options help provide efficient heating and cooling.

Highly Efficient Operation

Falling Film Type

Unlike flooded evaporators, falling film types drip refrigerant from distributors over stacked tubes, providing direct contact with each tube for greater efficiency with less refrigerant.

Highly Reliable Technology

    Back Up Operation

    The LG Ice Thermal Storage Screw Chiller offers continuous operation through an automatic emergency backup if an issue occurs in one compressor or cycle. This enhances system reliability and provides stable performance.

  • Structural diagram illustrating the Oil Recovery System process.

    Oil Recovery System

    During high-speed rotation of the compressor, the supplied oil is recovered through a three-stage separation system. The three-stage oil recovery system minimizes the amount of oil during refrigerant circulation, improving cooling efficiency. Continuous oil supply and recovery prevents oil shortage.

* Back Up Operation function is available for over 2 compressor models.

Convenient Installation & Control

  • LG Water-cooled Screw Chiller 1 Compresoor model shown with reduced footprint highlighted below.

    Reduced Weight & Size

    The Ice Thermal Storage Screw Chiller utilizes installation area efficiently and features a reduced weight design.
