Summary

The paper presents the construction, newly developed design technologies and performance features of a compact horizontal scroll-type compressor for room air conditioners. The authors were able to develop a compact variable speed horizontal scroll-type compressor with a cooling capacity of 1.8 kilowatt, which necessitated the development of new mechanisms, including an axial compliance mechanism for compensating liquid compression, an oil-pump mechanism for lubrication and a suppression mechanism for oil discharge. Use of the new compressor in room air conditioners made it possible to reduce the external unit of the air conditioner by about 25%. The new compressor is about 10% more efficient, particularly at low speeds.
