Motor reversal switching system

摘要

The present invention involves a reversible, dual capacity compressor system. The compressor systems includes a reversible compressor, a pressure sensor, and a control assembly. The reversible compressor operates at a first capacity when the compressor rotates in a first direction and at a second and lesser capacity when the compressor rotates in a second direction. The pressure sensor is coupled to the compressor and generates a high pressure signal and a low pressure signal. The control assembly is coupled to the compressor and the pressure sensor and controls the compressor to rotate in the first direction when receiving a high pressure signal from the pressure sensor and to rotate in the second direction when receiving a low pressure signal from the pressure sensor.
