AIR CONDITIONER OUTDOOR UNITS

摘要

Air conditioner outdoor units provided with a non-electrically-driven compressor and an electrically-driven compressor suffer from the problem of reduced reliability of the air conditioner outdoor unit because when the electrically-driven compressor is started at a low temperature, oil-foaming, in which refrigerant dissolved in a refrigerant oil produces foam, occurs, and the oil is discharged into the circuit through a discharge opening causing the refrigerant oil in the electrically-driven compressor to be insufficient. A bottom plate (122) is divided into two regions by a straight horizontal line extending in the depth direction of a machine chamber (101) through the center of the bottom plate (122) of the machine chamber (101). The approximate center of an engine compressor unit (123) comprising an engine (111) and the non-electrically driven compressor (112) and the approximate center of the electrically-driven compressor (113) are both located in one of said two regions.
