Refrigerant is crucial for efficient cooling and heat transfer in air-cooled chillers. When a chiller has low refrigerant levels, its cooling capacity decreases, causing higher energy consumption, excessive compressor strain, and potential equipment failure.
Identifying early symptoms of an undercharged refrigerant can help prevent costly repairs and system inefficiencies. EKG (Malaysia) Sdn Bhd provides expert refrigerant diagnostics, leak detection, and gas recharging services, ensuring optimal cooling performance and energy efficiency.
Our ISO-certified refrigerant services cater to:
Industrial & Manufacturing Facilities
Commercial Buildings (Offices, Malls, Hotels, Hospitals)
Data Centers & IT Cooling Systems
Pharmaceutical & Healthcare Cooling
Food Processing & Cold Storage Units
1. Reduced Cooling Efficiency
Struggles to maintain the desired setpoint temperature
Cooling output is weaker than usual, even in normal operating conditions
Takes longer to reach required cooling levels
2. Higher Energy Bills & Increased Power Consumption
Compressor runs longer than usual to compensate for low refrigerant levels
Chiller consumes excessive electricity, leading to higher operational costs
Energy efficiency ratio (EER) decreases, affecting overall performance
3. Ice Buildup on Evaporator Coils & Refrigerant Lines
Ice formation appears on evaporator coils and suction lines
Indicates improper heat absorption due to insufficient refrigerant
Can lead to airflow blockages and frozen coils, further reducing cooling performance
4. Frequent Compressor Short Cycling
Chiller turns on and off frequently to maintain cooling levels
Short cycling increases wear and tear on the compressor, reducing lifespan
Causes unstable cooling performance and inconsistent temperature regulation
5. Hissing or Bubbling Noises
Audible hissing or bubbling sounds coming from the refrigerant lines
May indicate low refrigerant pressure or gas leaks within the system
Suggests the presence of air or moisture contamination inside the refrigerant circuit
6. Overheating & High Compressor Discharge Temperature
Compressor operates at higher temperatures than normal
High discharge temperature results in overheating, which can damage compressor components
Lack of proper refrigerant levels reduces lubrication, increasing friction and system stress
7. Low Suction & Discharge Pressures
Refrigerant pressure readings are below normal operating range
Low suction pressure reduces evaporator efficiency, causing inadequate cooling
Low discharge pressure leads to poor heat rejection in the condenser
1. Refrigerant Level Inspection & Leak Detection
Perform pressure testing and temperature analysis to diagnose refrigerant charge levels
Use ultrasonic and electronic leak detection technology to pinpoint refrigerant leaks
Inspect compressor, condenser coils, expansion valves, and refrigerant piping
2. Safe & Efficient Refrigerant Recharging
Refill air-cooled chillers with approved refrigerants (R-32, R-410A, R-134a, R-513A, R-407C, R-22, R-1234ze)
Ensure precise refrigerant charge levels to prevent overcharging or undercharging
Apply leak-sealing solutions to prevent further refrigerant loss
3. Compressor & Expansion Valve Optimization
Adjust expansion valve settings for proper refrigerant flow and heat exchange
Optimize compressor cycling to enhance energy efficiency and system reliability
Monitor suction and discharge pressure levels for refrigerant flow stability
4. Performance Testing & Final System Validation
