Evaluation of Air Conditioner Performance using Different Methods of Temperature Measurement

Performance evaluation of an air conditioner using R410a has been evaluated by field measurement pressure and temperature at suction discharge line. Two methods were used for measurement. First, the sensors mounted on outer wall pipe second, inserted into refrigerant flow in pipe. Using second method, is averagely 5.0°C lower 17.8°C higher than that first method. The coefficient performance power consumption resulted from method a good agreement with standardized test according to ISO 5151:2017. This indicates sensor insertion gives better accuracy conditioner.
