How can we help you?

• Determine actual refrigeration capacity Q0 and COP at PCA AB 308 accredited laboratory
• Conduct energy balance of compressor-condenser unit and identify efficiency reserves
• Order mobile thermal testing directly at your cold store or freezer without equipment transport
• Identify causes of excessive energy consumption and reduce refrigeration system operating costs
• Obtain test report in Polish and English accepted by energy auditors

Thermal Testing Scope

COCH Laboratory performs thermal testing covering:

• Refrigeration capacity Q0 [kW] measurement
• COP and EER determination
• Energy balance of compressor-condenser unit (compressor power, cooling, condenser heat rejection)
• Temperature and pressure measurements at system nodes (evaporator and condenser inlet/outlet)
• Heat exchanger efficiency assessment (LMTD, U·A)
• Heat loss, thermal bridge, and insulation leak identification
• Control stability analysis (TEV/EEV expansion valve performance)

Measurement Methods

• Calorimetric method (refrigerant enthalpy measurement)
• Refrigerant mass flow measurement method
• Heat transfer fluid flow measurement (water-side installation)
• Multi-channel data logger recording (1 Hz)

On-Site Testing

COCH operates a mobile measurement kit enabling complete thermal testing of installations directly at client sites - cold stores, freezers, air handling units, and production halls.

Typical Applications

• Commissioning acceptance testing (verifying declared parameters)
• Diagnosis of low efficiency or high energy consumption
• Comparative testing before and after system modernisation
• Documentation for energy audits
