LTD Analysis/Tube Cleaning

Increase Chiller’s Efficiency with Tube Inspection

Leaving temperature differing (LTD) analysis improves chiller performance and efficiency through checking tube cleaning time and providing customer water quality management guide.
Note)
LTD(Cond.) = Cond. Ref. Temp. – Cooling Water Outlet Temperature
LTD(Evap.) = Chilled Water Outlet Temperature – Evap. Ref. Temp.
  • A two-dimensional straight graph Representing LTD Analysis.

    LTD Analysis

    LTD lift is an index that shows whether the heat exchange performance of your chiller’s tube is deteriorating (LTD Management Criteria: Below 3°C).

  • An engineer is cleaning dirty tubes.

    Tube Cleaning

    Scales inside the heat tube interfere with heat transfer, reducing the life time and efficiency of the device, so regular cleaning is required.

  • Three-dimensional bar graph, expressing energy efficiency.

    Benefit

    Better performance and reduced energy consumption improve your chiller's reliability (Actual improvement values may ​​vary by site).

Oil Replacement

Securing Reliability of the Compressor’s Internal Parts

Regular oil replacement improves the durability of core parts ensuring stable product management.
  • Oil flows out of a barrel with an open lid, and next to it is a graph about the time of oil replacement.

    Oil Change and Analysis

    The replacement cycle is analyzed through oil differential pressure analysis and replaces it with LG pure oil to secure reliability of parts. Analysis of oil can be added upon customer request.

  • A quarter of the chiller component is exposed, revealing a complex interior filled with intricate metallic parts.

    Benefit

    Prevention of damage to core components due to lack of lubrication

A graph plots head on the y-axis against inlet flow on the X-axis. Five arch lines intersected by two lines, with a red surge area indicated. A graph plots head on the y-axis against inlet flow on the X-axis. Five arch lines intersected by two lines, with a red surge area indicated.
Surge Analysis & Prevention

Secure Compressor Integrity with Surge Prevention Logic

A service to prevent damage to key compressor components and to reduce energy consumption through reducing number of surge occurrences.
  • A two-dimensional graph about analyzing the time of surges occurred.

    Surge Analysis

    The time of surges occurred in the compressor are analyzed.

  • A two-dimensional graph shows surges prevention Logic through self-learning.

    Surge Prevention Logic Application

    Surges are prevented by resetting self-learning surge lines.
    Note) A: Early Surge Line / B: Real Surge Line / C: Map Surge Line

  • A two-dimensional graph shows benefit through surge analysis.

    Benefit

    Prevention of compressor components damage, energy reduction, and stable product operation.
