Energy Cost Saving
What is LTD?
LTD (Log Mean Temperature Difference) evaluates heat exchange performance between refrigerant and water LTD analysis verifies tube heat transfer efficiency, predicts optimal cleaning cycles, and improves chiller efficiency while reducing energy consumption
Causes and Effects of Increased LTD
Condenser LTD
Condenser heat exchanger tube contamination, poor cooling water quality, non-condensable gases
Increased compressor power demand, reduced efficiency, condenser pressure surge causing compressor burnout
Evaporator LTD
Evaporator heat exchanger tube contamination, refrigerant leakage, poor refrigeration cycle
Reduced cooling capacity and evaporator pressure
Improving LTD Through Tube Cleaning
Data extraction (USB, CatM1)
LTD analysis
Tube cleaning
Before/after analysis report
Minimize energy loss by reducing compressor power demand
Prevent compressor damage from pressure surges
*Theoretical efficiency improvement: 7% when condenser LTD improves from 3℃ to 1℃. Actual results vary by site conditions
Annual Operation Data Analysis
Analyze annual operation data to assess load and operating range, evaluate chiller operation patterns (load/head), and recommend optimal compressor types and operating strategies for energy reduction
Data extraction (USB, CatM1)
Discharge superheat analysis
Run-time and range analysis
Review chiller load and operation range based on annual operation data
Prevent compressor damage from frequent surges
Prevent energy loss from inefficient operation under high head or low load conditions
Recommended Solutions Based on Analysis

*Actual energy savings vary by country and site conditions
Chiller Overhaul
Why Do Chillers Need Overhauls?
Secondary Failure
Essential Solutions for Regular Inspections
Major component wear can cause high-risk secondary failures. System operation impact requires repair within 30 days
Reduced Performance and Durability
Performance Degradation and Durability Issues
Worn components cause compressor degradation, leading to reduced system performance and efficiency
Management Challenges
Operational Management Issues
Secondary failures often cause extensive damage, including chiller shutdowns. Failures lead to complaints and extended repair times, affecting business operations
Efficiency Improvement
Overhauls ensure smooth refrigerant compression, improving performance. Rotating part inspection and replacement enhance durability and operation efficiency for energy savings
Lubrication System
Proper lubrication system ensures smooth oil supply, preventing secondary failures in bearings and motors
