Optimizing the performance of refrigeration systems is critical to energy efficiency and equipment life. We specialize in comprehensive thermal studies of refrigeration systems to maximize the efficiency of refrigeration systems and minimize operating costs.
What are thermal tests of refrigeration systems?
What kind of research do we do?
Our services include a detailed analysis of the operating parameters of refrigeration systems, including an assessment of energy efficiency, identification of potential sources of energy losses and recommendations for system optimization. With state-of-the-art technology and an experienced team of experts, we provide the highest quality research services.
Measurements of temperature, pressure, refrigerant/coolant flow:
Our tests include precise measurements that are crucial to the efficiency and safety of refrigeration systems. We measure, among other things:
- Evaporation and condensation temperatures
- Refrigerant pressures before the compressor
- Refrigerant flow through the system
Measurements of temperature, humidity, air velocity:
In our analysis, we take into account the climatic parameters affecting the operation of the plant:
- Air temperature and humidity
- Air velocity
Temperature testing of the elements:
We take detailed temperature measurements at key points in the system, such as:
- Oil temperature before and after the radiator
- Cooling water temperature before and after the oil cooler
- Cooling air temperature before and after the condenser
- Condenser inlet and outlet water temperature
- Temperature in the evaporator space (between the fins)
- Temperature before the expansion valve
- Chilled water temperature upstream and downstream of the chiller
Measurements of climatic parameters:
In addition, we measure key climate parameters, such as:
- Air temperature and humidity
- Air velocity
- Pomiary wielkości elektrycznych:
Measurements of electrical quantities:
In addition to thermodynamic and climatic parameters, we also measure electrical quantities in refrigeration systems:
- Electrical power consumed by compressors, pumps, fans, generators and other equipment
- Current, voltage, frequency
- Leakage current, inrush current, short circuit current
- Active, reactive power
- Insulation resistance
- Order of phases
Through comprehensive surveys, we provide our customers with a complete picture of the performance of their refrigeration plants and recommendations for optimization and energy efficiency improvements.

Importance of Precision Measurements in Diagnostics of Refrigeration, Air Conditioning and Heat Pump Equipment
In the diagnosis of refrigeration, air conditioning and heat pump equipment, precise measurements of various technical parameters play a key role. The most commonly used techniques are the measurement of temperatures, pressures and flows of factors associated with the operation of these systems. These tests are designed not only to monitor the technical condition of the equipment, but also to assess its energy efficiency and identify potential problems and failures.
Temperatures are measured at various points in the system, such as refrigerant evaporation and condensation points, before and after components like oil coolers and condensers. Pressures, on the other hand, are monitored before and after compressors and at other key points in the system. In addition, measurements of refrigerant flows make it possible to assess the performance and smoothness of the refrigeration system.
Another important aspect of diagnostics is electrical measurements, which include monitoring the power consumed by compressors, fans and other equipment, as well as current, voltage and frequency. These data are crucial to ensure the safe and efficient operation of equipment.
Controlling the climatic conditions under which the equipment operates also plays an important role. Parameters such as temperature and humidity affect the operating efficiency of refrigeration systems and their energy efficiency.
In summary, precise measurements of the quantities characteristic of refrigeration, air conditioning and heat pump equipment are essential to ensure their proper functioning and optimize their operation. Regular diagnosis and monitoring of these parameters allows quick response to possible technical problems and prevention of failures, which translates into longevity and efficiency of refrigeration and air conditioning systems.
