Abstract
A transport climate control system includes a controller. When a pulldown operation is scheduled or performed, the controller can incorporate operation in a lubricant recovery mode into the pulldown operation, and operate the transport climate control system to perform the pulldown operation including the operation in the lubricant recovery mode. The lubricant recovery mode can include operation under conditions such as mass flow rates, compressor speed and/or compressor capacity supporting lubricant circulation, so as to return lubricant to the sump.
