Abstract
A paver work machine comprises of a hopper, a screed, a thermal manage system with a heat pump, and a controller. The hopper receives and distributes paving material, and the screed levels the paving material on the ground surface. The thermal management system includes a thermal energy circuit for circulating a medium through an evaporator, a compressor, a condenser, and an expansion device. The compressor receives the medium from the evaporator and is operable to compress and circulate the medium through the thermal energy circuit. The evaporator receives the medium from the expansion device and is operable to transfer heat to the medium. The condenser is operable to desorb heat form the medium and adapted to transfer heat desorbed from the medium to one or more the hopper or the screed. A controller controls heat transfer between the condenser and one or more of the screed and the hopper.
