Abstract

In this study, the continuous operation and efficiency variation of a portable air conditioner under high-humidity conditions were experimentally studied by changing the condenser path and condensate supply method. By applying countercurrent path, drain hole, and optimized splash fan position and structure, the coefficient of performance (COP) could be enhanced by approximately 8.1% without increasing the cost. However, the increase in condensate made continuous operation impossible under high humidity conditions of 90% or more as it was optimized for operation at a relative humidity of 50% based on the general capacity measurement conditions in the market. To increase the operating time under a 90% relative humidity condition, cycle temperature and surface abnormalities were evaluated. The cycle temperature of the condenser increased before the end of the continuous operation. The condensate did not evaporate from the surface of the condenser at a sufficient rate and the blocked area increased. Finally, the continuous operation time can be extended by changing the cycle by using an electronic expansion valve.
