A novel simple measuring method of actual performance of room air-conditioners by neural net work analysis (NNW) has been developed. The actual performance for a long term which is difficult to be measured by air enthalpy method is able to be measured easily by this method. In other words, actual performance of room air-conditioners can be measured by the proposed NNW method without measurement of air flow at indoor unit and outdoor unit which changes due to clogging of heat exchanger by dust. In order to gather data for training and testing the proposed NNW method, the room air-conditioner for experiment was set up. Inputs to NNW are outdoor temperature, indoor temperature, indoor wet-bulb temperature, inlet temperature of evaporator, outlet temperature of evaporator, condensation temperature and power consumption. The output from NNW is COP. The COP by NNW method has mean errors under 2.8% in quasi-steady operation condition and has mean errors under 4.6% in unsteady operation condition, compared to the COP of air enthalpy method. Results show that the COP of air conditioners can be measured easily for a long term using NNW within a high degree of accuracy.
