Abstract
Disclosed are climate systems and methods for control the climate systems. A climate system includes a plurality of compressors arranged in parallel, a condenser disposed downstream of the compressors and an evaporator disposed downstream of the condenser. The compressors, the condenser, and the evaporator are fluidly connected by refrigerant lines to form a refrigerant circuit. The climate system also includes a controller that controls the operation of the compressors to draw back lubricant to the compressors without use of an oil equalization system.
