What is Zubadan Technology?
Zubadan is an advanced technology specifically developed by Mitsubishi Electric to deliver maximum efficiency and comfort regardless of weather conditions. Also known as Zubadan Inverter, it provides full heating capacity down to -15°C and a guaranteed operating range at temperatures as low as -30°C.
The systems feature optimized defrost operation—intervals between defrost cycles can reach up to 150 minutes, while the defrost duration is reduced by 50% compared to standard models. Thanks to the hyper-inverter series from Mitsubishi Electric, you can rely on a dependable ally during cold winter days.
“Zuba” derives from the Japanese word “zubbato,” meaning precisely or exactly at the right moment, while “Dan” means heat. The name itself indicates that, with its extensive heating capabilities, Zubadan sets new standards in thermal efficiency.
How Does a Heat Pump Work?
The fan draws air from the outdoor environment and directs it to a heat exchanger where refrigerant circulates. Even at low temperatures, the refrigerant evaporates and transitions into a gaseous state.
The compressor draws in this gas and compresses it, increasing its temperature and pressure.
The hot refrigerant then flows to a second heat exchanger (the condenser), where it transfers the accumulated heat to the home’s heating system.
After cooling, the refrigerant condenses back into a liquid and returns to the first heat exchanger, ready for a new cycle.
Because the heat pump efficiently extracts heat even from cold air, it produces more energy than it consumes.
When the outdoor temperature drops below 0°C, the amount of refrigerant passing through the compressor decreases, and with it the amount of heat produced. Mitsubishi Electric’s specialized technology solves this issue by regulating the refrigerant flow through the compressor and ensuring a constant flow rate even under severe winter conditions.
Key Advantages of Zubadan Technology
Improved heating capacity at low temperatures
With Flash Injection technology, Zubadan provides full heating capacity even at outdoor temperatures down to -15°C, while the reliable operating range extends to -30°C.
Rapid recovery after defrosting
The technology enables a faster return to a comfortable temperature after the defrost phase, with minimal response time.
High energy efficiency
Zubadan ensures efficient operation in both heating and cooling modes, resulting in significantly reduced energy consumption.
Flash Injection Technology
In conventional heat pump systems, when the outdoor temperature is low, the volume of refrigerant circulating through the compressor decreases. This occurs due to the reduced refrigerant pressure, which may lead to compressor overheating and a reduction in heating capacity.
Flash Injection technology addresses this issue by injecting additional refrigerant, maintaining the circulation volume and compressor load, thereby preserving stable heating capacity even at very low outdoor temperatures.
Improved Defrost Technology
One of the key advantages of Zubadan is the exceptionally fast restoration of heating after the defrost cycle. Compared to conventional systems, the Zubadan heat pump restores heating up to twice as fast.
Its intelligent self-regulating system operates only until the heat exchanger is fully defrosted, which saves energy and improves overall efficiency. Enjoy higher comfort and lower operating costs with the heating technology of the future.
Why Choose a Heat Pump with Zubadan Technology?
Heat Pump systems featuring Zubadan technology by Mitsubishi Electric set a high standard for heating solutions in cold regions. Choosing this technology not only ensures superior comfort but also significantly reduces energy consumption.
If your region experiences extremely low winter temperatures, or if you require guaranteed heating capacity without compromise or the need for supplementary heating, then this technology is the ideal solution for you.
