The world’s first* two-pipe system that simultaneously cools and heats
(Nominal 22.4 – 124.0kW cooling / 25.0 – 140.0kW heating).
*As of 1992 (according to our in-house survey)

Simultaneous heating and cooling

The R2 system provides simultaneous cooling and heating. With the BC Controller connecting several indoor units to one outdoor unit using only two pipes and energy-saving heat recovery operation, economy and efficiency are guaranteed. Smooth auto-switching (heating and cooling) based on a set temperature realizes convenient operation and a comfortable environment.

New Heat Exchanger Technology

The heat exchanger of the outdoor unit has been drastically changed. Our new EP (high COP) model’s use a world-first aluminum flat-tube heat exchanger as a heat exchanger of the outdoor unit. The flat tubes can reduce airflow resistance, and the larger number of tubes can be installed in the flat-tube heat exchanger compared to our conventional heat exchanger, which can increase the surface area that is in contact with the refrigerant, and the heat exchange performance can be greatly improved. Our new air conditioner can, therefore, operate at higher SEER/SCOP, and maintain the required cooling/heating capacity.
