Kelon Inverter Air Conditioner 18000BTU

For the rooms a smaller aircon can't keep up in. Twelve thousand BTU handles a bedroom. Eighteen thousand handles what comes after — the open-plan lounge, the larger main bedroom, the family room that stretches into the dining area, the small business floor. The Kelon 18,000 BTU Inverter Air Conditioner delivers ~4,800W of cooling and ~5,100W of heating — roughly 50% more output than a 12,000 BTU unit — sized for rooms in the 30 to 45 m² range where a smaller aircon just can't keep the temperature where you set it. Under the hood is the same variable-speed inverter compressor technology used across Kelon's range, but scaled up for the higher heat load. Instead of thumping on and off at full power to hold the room at temperature (the traditional AC pattern), the inverter compressor ramps up and down continuously — pulling more power when the room's climbing above set point, backing off when it's stable. On a larger room with a bigger heat load, that modulation matters more, not less. Constant on/off cycling on a big room wastes energy; a modulating inverter compressor doesn't. WiFi control connects the unit to your phone through the Kelon app. Adjust temperature, switch modes, set schedules, or shut it off from anywhere with a signal — useful for pre-cooling a lounge before an evening event, or making sure the office aircon is off after everyone's gone home. Standard convenience features are all here too: sleep mode, timer function, auto restart after power interruptions, and the remote control. Refrigerant is R410A, cooling EER is ~3.0 W/W, and heating COP is ~3.61 W/W — the reversible-cycle design means one unit handles both summer cooling and winter heating (with better efficiency than resistive electric heaters in the process). Indoor noise on the low setting runs at 36 dB(A) — quiet enough for a lounge where people are watching TV or working.
