2. Design Comparison of Daikin FBFC50DVM9/RZFC50DVM and Panasonic S-1821PF3H/U-18PR1H5 Air Conditioners
Comparing the design of both products, each consists of 1 outdoor unit and 1 indoor unit. The design of the Panasonic air conditioner tends to be more modern, while the Daikin FBFC50DVM9/RZFC50DVM air conditioner leans towards a simpler style.
Regarding the indoor unit, Daikin's air conditioner is smaller in size but heavier compared to the Panasonic S-1821PF3H/U-18PR1H5 air conditioner. Thus, the Daikin FBFC50DVM9/RZFC50DVM air conditioner is suitable for rooms with low ceiling height that require space-saving installation.

Concerning the outdoor unit, the sizes of both types are quite similar, but the Daikin air conditioner is heavier than Panasonic, making installation more difficult.
3. Power Consumption Capability
Both devices are equipped with Inverter energy-saving technology by the manufacturers to save energy and maintain smooth operation. Specifically, according to the announcements of the companies, the power consumption of Daikin air conditioner, including the model Daikin FBFC50DVM9/RZFC50DVM, is 1.56 kW, while Panasonic S-1821PF3H/U-18PR1H5 air conditioner is 1.54 kW. Therefore, despite having the same cooling capacity index of 18,000 BTU, Panasonic S-1821PF3H/U-18PR1H5 air conditioner consumes slightly less power than Daikin FBFC50DVM9/RZFC50DVM air conditioner 1 bit.
4. Cooling Technology
Both products utilize R32 refrigerant, providing high cooling efficiency and environmental friendliness. Moreover, combined with a copper heat exchanger in the Panasonic air conditioner and an aluminum heat exchanger in the Daikin FBFC50DVM9/RZFC50DVM air conditioner, they enhance cooling performance and prevent environmental impacts on the outdoor unit, thus prolonging the lifespan of the air conditioner. The copper heat exchanger of Panasonic ensures better heat dissipation, cooling efficiency, and corrosion resistance compared to the aluminum heat exchanger of Daikin.

5. Bacteria Elimination Technology
The Daikin FBFC50DVM9/RZFC50DVM air conditioner is equipped with a silver ion antibacterial drain pan in the indoor unit to inhibit the growth of grease, mold, and bacteria. Meanwhile, the Panasonic S-1821PF3H/U-18PR1H5 air conditioner is equipped with Nanoe X antibacterial technology, which eliminates bacteria and odors in the air by up to 99%, protecting users' health. Nanoe X technology is Panasonic's proprietary technology developed after Daikin's silver ion antibacterial drain pan, so this technology still remains more experimental.

In conclusion, both the Panasonic 18,000BTU S-1821PF3H/U-18PR1H5 air conditioner and the Daikin 18,000BTU FBFC50DVM9/RZFC50DVM air conditioner have their own pros and cons. With a higher price, Panasonic's air conditioner features modern design, convenient installation, lower power consumption, and higher durability. On the other hand, Daikin's air conditioner, with a slightly lower price, has a simpler design, technologies tested over time, and more space-saving installation.
