Air conditioner (heat pump) Mitsubishi SRK-SRC20ZTX-WA Kazan Arctic series

The Mitsubishi Heavy Industries Kazan Arctic 20ZTX-WA is a high-efficiency inverter air-to-air heat pump designed for year-round indoor comfort. It provides efficient cooling in summer and reliable heating during cold winter conditions.
The system combines Mitsubishi Heavy Industries' advanced inverter technology with excellent seasonal efficiency, achieving A+++ energy efficiency in both cooling and heating modes. With a SEER of 9.60 and SCOP of 5.20, it is designed to provide high efficiency while keeping energy consumption under control.
The Kazan Arctic series is developed for cold-climate operation. The SRK20ZTX-WA / SRC20ZTX-WA system has a manufacturer-specified heating operating range down to -25°C, while the Kazan Arctic series is marketed for operation in very cold conditions. At -20°C, the 20ZTX-WA model can deliver up to approximately 3.9 kW of heating capacity.
The system uses the modern R32 refrigerant and features 3D AUTO airflow control, which helps distribute air evenly throughout the room. The indoor unit operates from just 19 dB(A) at its lowest fan speed, making it suitable for bedrooms and other noise-sensitive areas.
Built-in Wi-Fi connectivity allows the system to be controlled remotely from a smartphone, including temperature and operating-mode settings.
