By having a mechanism to switch-off one of two cylinders, ”Dual Rotary Compressor” has become the best candidate to operate in wide range load condition. But the conventional mechanism still has some problems such as a decrease in efficiency in 2-cylinder operation, space-consuming pipe fittings and difficulties of application to highly-efficient models. We have developed a new mechanism which can solve those problems, and succeeded in commercialization for room air-conditioners. The new space-saving dual rotary compressor is more efficient 3% in APF than conventional model.
