R290 room air-conditioner simulation based on SINDA/FLUINT

Liang Jierong,Li Tingxun(School of Engineering,Sun Yat-sen University,Guangzhou 510725,China)  
R290 is environment-friendly natural refrigerant,but it is flammable.According to IEC 60335 the charge is limited strictly in room air conditioner(RAC).In this paper,simulating models of R290 room air conditioner were developed based on SINDA/FLUINT,and the models were verified by comparing the simulated temperature distribution and system performance like COP and indoor air humidity with experiment results.With the models,the R290 mass distribution and pressure drop among the RAC components were calculated.It is found that refrigerant concentrates in condenser(62%),while pressure drop is mainly produced in evaporator,liquid line and vapor line.
