Device for climate control of a driver's bed

Abstract

A device for climate control of a vehicle is provided which includes a coolant circuit in which coolant flows through a compressor, a condenser, and an evaporator; a heat transfer medium circuit in which heat transfer medium flows through a heat source and a heat exchanger; and a heat/cold reservoir in which the evaporator and the heat exchanger are located. The device provides an improved and comparatively economical approach to climate control in the area of a driver's bed in a motor vehicle interior by, at least in part, using multiple heating/cooling surfaces for a driver's bed and/or vehicle interior wall, which is integrated into the heat transfer medium circuit in a parallel relationship to each other such that the heat transfer medium can flow selectively through the heating/cooling surfaces, or the heat transfer medium which is conveyed by the heat source can flow through the heating/cooling surfaces.

1 . A device for climate control of a vehicle interior, comprising: 
 a coolant circuit in which coolant flows therethrough;    a compressor positioned in the coolant circuit;    a condenser positioned in the coolant circuit;    an evaporator positioned in the coolant circuit;    a heat transfer medium circuit in which a heat transfer medium flows therethrough;    a heat source positioned in the heat transfer medium circuit;    a heat exchanger positioned in the heat transfer medium circuit;    a heat/cold reservoir in which the evaporator and the heat exchanger are located;    a heating/cooling surface for at least one of a driver's bed and vehicle interior wall, said heating/cooling surface being integrated into the heat transfer medium circuit such that at least one of a heat transfer medium flowing through the heat exchanger can flow selectively through the heating/cooling surface and a heat transfer medium being conveyed by the heat source can flow through the heating/cooling surface; and    a second heating/cooling surface for at least one of a second driver's bed and a second vehicle interior wall, said second heating/cooling surface being located in a parallel connection to the first heating/cooling surface.    
   
   
       2 . The device of  claim 1 , further including a first valve positioned to permit remote control of said first heating/cooling surface and a second valve positioned to permit remote control of said second heating/cooling surface.  
   
   
       3 . The device of  claim 1 , further including a common valve is positioned to permit remote control of the flow of heat transfer medium to the parallel connection and thus to the first and second heating/cooling surfaces.  
   
   
       4 . The device of  claim 1 , wherein the second heat exchanger is adapted to receive an air flow therethrough.  
   
   
       5 . The device of  claim 4 , wherein at least one of the first and second heating/cooling surfaces is series connected to the second heat exchanger, further including a bypass line positioned to bypass flow around said first and second heating/cooling surfaces and formed with an adjustable flow cross section.  
   
   
       6 . The device of  claim 4 , wherein at least one of the first and the second heating/cooling surfaces is located in a parallel connection to the second heat exchanger.
