Remarkable innovation for the heat exchanger!. Samsung’s Multi Jet Technology increases the heat exchange surface with multi channel flow, and with its new flat surface design, it reduces air resistance compared to conventional heat exchangers. Therefore, the cooling efficiency has been improved! Instant heat exchange for faster cooling. Compared to conventional ones, Samsung Multi Jet Technology heat exchanger performs faster, resulting in faster heat exchange. So, your space cools instantly. Smaller size for easier installation: Samsung’s Multi Jet Technology heat exchanger makes the outdoor unit smaller, which allows for easier transfer and convenient installation. Though it has advantages I would not prefer it. Samsung is brand which deals with electronics items. AC is not among their cup of tea.
