Research on Evaluation Method of Long Term Energy Saving Performance of Air-conditioner

Evaluation method of long term energy saving performance of air-conditioner was introduced. According to the practical case, the experiments were performed for three periods through artificial simulating rain and dust tests to accelerate aging of air-conditioner performance. Long term energy saving performance of air-conditioner was analyzed by means of the performance degradation rates of refrigerating capacity, energy efficiency ratio and energy efficiency load. With the aging of air-conditioner, the performance degradation rates of refrigerating capacity and energy efficiency ratio had descending trends.
