Abstract
The present invention provides a system for heating a compressor assembly of a heating, ventilation, and air conditioning (HVAC) system. The system comprises a heat source for transferring thermal energy to a plurality of compressor units. A controller varies the thermal energy transferred to the compressor units, between at least two substantially non-zero rates of transfer of thermal energy, in a plurality of modes of operation of the HVAC system.
