Abstract：In the portable air conditioner(PAC),the condensate is sprayed on the high temperature fin of the condenser by the centrifugal atomization of the water-wheel,and then discharged through the exhaust duct after heating.But its atomization capacity is limited,and artificial drainage is still needed under high-humidity conditions.A new atomization method(micro-hole high-speed jet atomization/nozzle atomization)is proposed,and we test the no-drainage capacity and the performance of PAC under high humidity conditions(t=27℃,RH=90％).The influences of water-wheel atomization and micro-hole high-speed jet atomization on the condensate removal capability and refrigeration system of PAC is compared.Compared with no condensate,the result shows that the refrigerating capacity increases by 3.16％(water wheel is 1.77％)and the Energy Efficiency Ratio(EER)increases by 11.70％(water wheel is 6.62％),and the continuous running time can be achieved for 24 h(water wheel is 6 h)for nozzle atomization.Therefore,the use of nozzle atomization has more advantages in improving the energy efficiency and no-drainage capacity of the whole machine.
