Optimisation through performance inspections.

Author(s) : BERGLÖF K.


The requirement for energy performance in the EU and on other markets can potentially improve the energy efficiency significantly - if well implemented. Many systems are not operating as the owners and contractors believe thay are. It has been documented that there is in many, not to say most cases, a significant deviation between design performance and achieved performance in the field. The internal method is based on easy to perform measurements of pressures and temperature of the refrigerant and the thermophysical data of the refrigerant. It is not required for the system to be specially prepared as all sensors can be connected in 20 minutes (or permanently mounted if so desired). The method allows the COP and capacity to be measured with good accuracy as well as identifying the performance and behaviour of each component in the system. This can all be done without flow meters or any manufacturer data. The internal method is suitable for commissioning, inspections and troubleshooting as it establish all characteristics in an independent and un-biased way.
