Performance inspections with innovative analysis equipment results in significant energy saving in air-conditioning and refrigeration systems.

Summary

The EU has implemented a requirement on “performance inspections” on an air-conditioning system above 12 kW. As 15-20% of the electrical energy in EU is used by refrigeration, air-conditioning and heat pumps units, the saving potential is significant. This paper presents an innovative method for performance inspections and practical experiences of optimisation through documentation of performance. The method is used at commissioning, trouble shooting, service and energy optimisation. The “internal method” for performance inspections has proven to be very useful to give detailed documentation of performance which is essential to optimise systems. Experiences from different sectors are presented. The method is cost effective to document COP/capacity as no costly installations of flow meters or preinstalled sensors are required. The method require 20-30 minutes set up and give capacity with an accuracy of plus or minus 7% and COP with plus or minus 5% for virtually any compressor driven refrigeration/air-conditioning system.
