The Akabishi RAZ-SE18VG-Y1 / RBZ-SE18VG-Y1 is a 1.5 Ton inverter split AC with Hot & Cold functionality and a 3-Star BEE rating, designed for users who want year-round comfort: cooling when it’s hot, heating when colder, all in one unit. It combines modern inverter technology, eco-friendly refrigerant, and enough power to handle medium to large living spaces (or rooms with moderate heat load) reliably.

• Performance & Flexibility
  Because it’s inverter type with hot & cold capability, the unit adjusts its compressor speed depending on the thermal load. In very hot weather, it works harder; when the room is near set temperature, it backs off. That results in smoother temperature control, less frequent on/off cycling, quieter operation in moderate conditions, and better comfort during both summer and cooler times.

• Refrigerant & Efficiency
  Uses R-32 refrigerant (lower GWP, good heat transfer) which helps heat/cool more efficiently. Rated 3-Star, it’s not the top efficiency class, but it delivers good performance for its capacity without making electricity bills very steep. The published ISEER is 4.2 for this model, which is quite respectable.

• Key Features
  Features include Anti-Mold Filter, Self-diagnostic, Econo Cool mode (likely to reduce power in moderate conditions), and hot & cold mode. These features enhance usability, air quality, and energy savings.

• Noise & Airflow
  Indoor airflow is strong: values for indoor air flow are ~ 1050 / 920 / 830 / 790 CMH for Turbo / High / Mid / Low fan speeds. Noise levels for the indoor unit are in the range ~ 44 / 45 / 48 / 51 dB(A) depending on fan speed. So, decent performance but expect some noise when Turbo/High speeds are used.

• Build, Dimensions & Installation
  Indoor unit size: 1000 × 230 × 295 mm, weight ~ 11.5 kg. Outdoor unit: 810 × 301 × 594 mm, weight ~ 31.3 kg. Pipe connection sizes: liquid / gas sides ~ 6.35 mm / 12.7 mm. Max pipe length ~ 15 m, height difference between indoor and outdoor ~ 10 m. Ambient operating range: from about –7°C (for heating) up to 48°C (cooling).

• Use-Case / Value
  Best for users in climates with significant season variation (needing heating + cooling), who want good power in moderate to high ambient heat, and value features like quieter low-speed operation, eco modes, filters, etc. While electricity cost will be higher than for smaller or lower-star units, the inverter + hot-cold combo make it more versatile.
