Heating and/or cooling device for omnibus passenger compartment with reheating circuit supplied via pump operated independent of vehicle IC engine

摘要

The device has a central circulation circuit (36), a cooling circuit (50) and a heating circuit (12), respectively extracting and supplying heat energy from and to the central circulation circuit, which is coupled to a load circuit (68,70) containing at least one heat exchanger (80,82) within the passenger compartment. A reheating circuit (118,120) having a reheating heat exchanger (96,98) associated with the latter heat exchanger is supplied with the heat transfer medium from the heating circuit via a pump (104) operated independent of the vehicle IC engine and contained in a second load circuit (66) having a heat exchanger (108) preceded by a distributor valve (116). An Independent claim for a vehicle provided with heating and/or cooling device is also included.
