Mitsubishi Electric introduces ZUBADAN series systems.
Translated from Japanese, it means “superheat”. It is known that air conditioners that use the low-potential heat of outdoor air for space heating reduce performance when the air temperature drops. And this reduction is very significant: at -20°C, the heating power is 40% less than the nominal value indicated in the device characteristics and measured at +7°C. For this reason, air conditioners in countries with cold winters are not considered a full-fledged heating device.
The attitude towards them has changed radically thanks to Mitsubishi Electric heat pumps based on ZUBADAN technology.
Stable Heat Capacity The heat capacity of the Mitsubishi Electric ZUBADAN Inverter semi-industrial series maintains its nominal value down to -15°C outside temperature. With a further decrease in temperature (the manufacturer guarantees the operation of outdoor units of the R2.UK series and older to a temperature of -28 ° C), the heating capacity begins to decrease. However, the advantages are retained both over traditional systems and over the energy-efficient systems of the POWER Inverter series. Comfortable space heating The injection circuit control algorithm can be optimized to achieve maximum heat output, for example when starting the system in a cold room. Another mode in which maximum performance is important is the defrosting mode of the outdoor heat exchanger (evaporator). The defrost mode, which cannot be avoided in air-cooled heat pumps, takes place quickly and completely unnoticed by the user. Two-Phase Injection Circuit The compressor’s unique two-phase refrigerant injection technology ensures stable heating output as the outdoor temperature drops.
