LG's round cassette air conditioners outperform competing products in both design and performance. Traditional indoor units of round cassette air conditioners include three separate air outlets that distribute air in three directions, resulting in blind spots. However, LG's new round cassette air conditioners reduce the connections of the round ventilation openings to distribute airflow evenly throughout the space, completely eliminating blind spots. Users can also take advantage of the six-stage crystal panels for precise control in directing cold or warm air to any desired location. This design offers double the accuracy in air flow control compared to the three-stage flow control provided by other round cassette air conditioners. LG conducted extensive air room tests to ensure the precise circular control of airflow achieves 30% faster cooling compared to other round cassette air conditioners available on the market. Even with this exceptional performance, the operational noise level emitted by LG's round cassette air conditioners does not exceed 39 decibels (A), which is lower than the typical noise level set for libraries at 40 decibels (A). These features contribute to making LG's round cassette air conditioners suitable for all customer environments.
