As a result of comparing the performance of wall-mounted air conditioning products sold on the market, it was found that Samsung Electronics had superior cooling speed, while LG Electronics products excelled in electricity cost savings.
On the 23rd, the Korea Consumer Agency (KCA) noted that such results emerged after testing and evaluating five types of wall-mounted air conditioners. The target products included one model each of 7-pyeong energy efficiency grade 1 products from LG Electronics (SQ07FS8EES) and Samsung Electronics (AR80F07D21WT), as well as one model each of 6-pyeong grade 5 products from Lukomz Electronics (A06T04-W), Carrier (OARB-0061FAWSD), and Haier (HSU06QAHIW).
The cooling speed of Samsung Electronics products was relatively superior. When the air conditioner was operated at maximum airflow to bring the temperature down from 35 degrees to 24 degrees, the time taken was 9 minutes and 53 seconds for Samsung Electronics products, making it the fastest, while Lukomz Electronics products took 14 minutes and 52 seconds, the slowest.
In a test comparing the set temperature and the actual temperature after running the air conditioner for 5 hours, the variations were smallest in the order of LG Electronics, Haier, and Samsung Electronics products.
When the air conditioner was operated at 24 degrees and maximum airflow, the noise generated from the indoor unit was quietest at 40 decibels (dB) with the 6-pyeong Carrier and Haier products.
As a result of a joint investigation conducted by the Korea Consumer Agency (KCA) and Korea Energy Agency (KEA), it was found that all five types matched their indicated energy efficiency grades with the measured grades. Safety and labeling also complied with all standards.
The monthly energy cost and carbon dioxide (CO₂) emissions for the grade 1 product from LG Electronics were the lowest at 17,000 won and 141 grams per hour, respectively. The same grade 1 product from Samsung Electronics was found to cost 19,000 won and emit 155 grams.
The price of Samsung Electronics products was 1.22 million won, more expensive than LG Electronics (approximately 1.197 million won), but it offered 25 additional functions, more than LG Electronics' 18 functions. The prices of three types of 6-pyeong air conditioners were in the 400,000 won range, with relatively fewer additional functions.
