COMPRESSOR ASSEMBLY WITH LIQUID SENSOR

摘要

A compressor may include a shell, a compression mechanism, first and second temperature sensors, and a control module. The shell may define a lubricant sump. The compression mechanism may be disposed within the shell and may be operable to compress a working fluid. The first temperature sensor may be at least partially disposed within the shell at a first position. The second temperature sensor may be at least partially disposed within the shell at a second position that is vertically higher than the first position. The control module may be in communication with the first and second temperature sensors and the pressure sensor and may determine whether a liquid level in the lubricant sump is below a predetermined level based on data received from the first and second temperature sensors.

1. A compressor comprising:
a shell defining a lubricant sump; a compression mechanism disposed within said shell and operable to compress a working fluid; a first temperature sensor at least partially disposed within said shell at a first position; a second temperature sensor at least partially disposed within said shell at a second position that is vertically higher than said first position; and a control module in communication with said first and second temperature sensors, said control module determining a difference between a first temperature measurement from said first temperature sensor and a second temperature measurement from said second temperature sensor, said control module determining whether a liquid level in said lubricant sump is below a predetermined level based on said difference.
