  • Patent number: 10976086
    Abstract: An air conditioner and a method for controlling the same are disclosed. The air conditioner implements a multistage expansion scheme by implementing serial connection between electronic expansion valves including in the R410A refrigerant-based air conditioner, and thus guarantees an optimum compression ratio in all cooling/heating load regions. Therefore, although cycle characteristics are changed by changing R410A refrigerant to R32 refrigerant, the air conditioner optimizes the cycle simply by controlling a degree of opening of electronic expansion valves, respectively. As described above, since the cycle optimization is implemented using the multistage expansion scheme in which legacy electronic expansion valves are coupled in series, the design modification is minimized without design modification of requisite constituent elements such as a heat exchanger, system implementation is facilitated, resulting in high efficiency in cost and productivity.
