Summary

This paper deals with the development of the performance evaluation method for a split air conditioning system using the compressor characteristic curve. In split air, air conditioning system, refrigerants expand directly in an evaporator and heat-exchange is done on the indoor unit. it is too difficult to measure the actual capacity and the accurate performance evaluation method is not established. The performance evaluation method using the compressor curve method based on the characteristic curve of compressor mass flow rate was developed. The authors examine the application of the method to this system which has different compressor type. The regression equations for refrigerant mass flow rate were obtained based on characteristic curve of the sliding vane compressor. The relative error between air conditioning capacity based on measurement and regression equation is obtained within 9.0%. The applicability of method for another type compressor is confirmed.
