Why is operating parameter optimization critical?

Maximizing efficiency of cooling systems, reducing energy bills, and extending refrigeration system lifespan.

Optimizing the operating parameters of refrigeration systems is critical for energy efficiency and the overall operational life of the equipment. We specialize in comprehensive thermal testing of refrigeration systems, which allows for maximizing the efficiency of cooling systems while minimizing operating costs.

Our services include detailed analysis of refrigeration system operating parameters, including energy efficiency assessments, identification of potential energy loss sources, and practical recommendations for system optimization. Thanks to state-of-the-art technologies and an experienced team of experts, we guarantee the highest quality of research services. We perform measurements both in our modern test chambers and directly at client facilities on-site.

Scope of thermal testing

We perform comprehensive diagnostics of refrigeration system operating parameters across the following measurement areas.

Temperature, pressure and refrigerant flow

High-precision measurements vital for the efficiency and safety of refrigeration systems.

  • Evaporating and condensing temperatures of fluid
  • Suction pressure of refrigerant before the compressor
  • Refrigerant mass/volumetric flow through the system

Air temperature, humidity and velocity

Climatic parameters that directly affect system performance and load.

  • Air temperature and relative humidity
  • Airflow velocity

Component and heat-node temperature profiles

Detailed temperature measurements at critical nodes of the cooling circuit.

  • Oil temperature before and after the oil cooler
  • Cooling water temperature before and after the oil cooler
  • Cooling air temperature before and after the condenser
  • Water temperature at the inlet and outlet of the condenser
  • Temperature inside the evaporator space (between fins)
  • Temperature before the thermostatic expansion valve
  • Chilled water temperature before and after the chiller unit

Additional climatic parameters

Ambient measurements supporting a complete thermal balance of the surroundings.

  • Ambient air temperature and humidity
  • Wind / airflow speed
  • Barometric pressure

Electrical parameter measurements

Integrated electrical diagnostics alongside thermodynamic and climatic testing.

  • Electrical power consumed by compressors, pumps, fans, chiller packs and auxiliary units
  • Current intensity, voltage and network frequency
  • Insulation leakage, startup inrush and short-circuit currents
  • Active and reactive electrical power demand
  • Winding insulation resistance of motors
  • Symmetrical power supply phase sequence

Through our comprehensive testing, we provide our clients with a full picture of their refrigeration plant’s performance along with targeted recommendations to optimize energy efficiency.

Advanced laboratory testing equipment

Our laboratory is equipped with regularly calibrated control and measurement instrumentation that guarantees high precision and reliability of results.

Manometers & pressure transducers

High-accuracy instruments for continuous monitoring and logging of pressures in high- and low-pressure circuits.

Thermometers, hygrometers & vacuum gauges

Digital dataloggers of climatic parameters and vacuum levels for diagnostics of components, ambient air and chilled spaces.

Mass & volumetric flow meters

Calibrated meters for liquid and gaseous refrigerants, cooling water, glycols and brines.

Vane & hot-wire anemometers

Air velocity meters for evaporators, air-cooled condensers and ventilation ducts.

Electrical power analyzers & multimeters

Analyzers recording active/reactive power demand, inrush currents and insulation resistance.

Tachometers & shaft speed sensors

Contactless laser devices for compressor shafts, axial fans and circulation pumps.

Frequently asked questions

Everything you need to know about the course, goals and benefits of thermal performance diagnostics.

The primary benefit is discovering hidden operational inefficiencies that force the system to run constantly at reduced efficiency (e.g., incorrect refrigerant charge, faulty expansion valves, or dirty heat exchangers). Our tests allow us to precisely calculate actual COP/EER ratios, locate energy losses, and provide an optimization plan that can reduce electricity consumption by 10% to 30% while extending compressor life.
