Patent ID: 7240725

Claim:
A device for climate control of a vehicle interior, comprising: a coolant circuit including a compressor, a condenser, and an evaporator; a heat transfer medium circuit including a heat source and a first heat exchanger; a heat/cold reservoir in which the evaporator and the first heat exchanger are located; and a heating/cooling surface integrated in the heat transfer medium circuit and being connected in parallel to the first heat exchanger; a second heat exchanger integrated in the heat transfer medium circuit and being connected in parallel to the heating/cooling surface; means for fluid conductively connecting the heating/cooling surface with the first heat exchanger, which means for fluid conductively connecting have a connecting and a non-connecting state; means for fluid conductively connecting the second heat exchanger with the first heat exchanger, which means for fluid conductively connecting the second heat exchanger have a connecting and a non-connecting state; means for fluid conductively connecting the heating/cooling surface with the heat source, which means for fluid conductively connecting the heating/cooling surface have a connecting and a non-connecting state; means for fluid conductively connecting the second heat exchanger with the heat source, which means for fluid conductively connecting the second heat exchanger with the heat source have a connecting and a non-connecting state; and a circulation pump integrated in the heat transfer medium circuit, which circulation pump is arranged for pumping at least part of said heat transfer medium, coming directly from said heat source, through said first heat exchanger.
