Abstract

A method of controlling a vapor cycle system (10) having first and second compressors (14,16) includes operating the first compressor (14) to compress refrigerant while the second compressor (16) is idle, sensing a motor temperature of the second compressor (16), activating a preheating mode in which the motor (16-1) of the second compressor (16) is powered to generate heat when the motor temperature of the second compressor is below a lower temperature threshold, turning off the preheating mode when the sensed motor temperature of the second compressor (16) is above an upper temperature threshold, and limiting the maximum duration of the preheating mode to a preheating time period, such that the preheating mode is turned off after being activated for the preheating time period.
