Abstract

A climate control system includes a compressor which includes a compressor housing, a compressor element provided in the compressor housing, a lubricant circuit, and an auxiliary sump. The lubricant circuit includes a lubricant sump provided in the compressor housing. The auxiliary sump is in fluid communication with the lubricant sump. A method for maintaining lubrication supply for a compressor of a climate control system includes transferring lubricant from the auxiliary sump to the lubricant sump of the compressor when a height of the lubricant in the auxiliary sump is greater than a height in the lubricant sump and returning the lubricant from the lubricant sump to the auxiliary sump when a height of the lubricant in the lubricant sump is higher than a height of a predetermined minimum level in the lubricant sump. The lubricant in the auxiliary sump and lubricant sump are equalized by gravity.
