Abstract

A vehicle temperature control system, for electric motor-powered vehicles or hybrid vehicles, includes a heater (18), which can be operated electrically or/and with fuel, with a first heat exchanger device (16) for transferring heat provided in the heater (18) to a first heat carrier medium provided in a first heat carrier medium circuit (12). An operating material tank (20) holds a liquid operating material (24). A second heat exchanger device (26) provides heat transfer between the first heat carrier medium provided in the first heat carrier medium circuit (12) and energy storage material (36) contained in the operating material tank (20). A third heat exchanger device (38) provides heat transfer between the first heat carrier medium provided in the first heat carrier medium circuit (12) and a second heat carrier medium provided in a second heat carrier medium circuit (40).

Dependent claims

A vehicle temperature control system comprising:

a heater operated electrically and/or with fuel, the heater comprising a first heat exchanger device for transferring heat provided in the heater to a first heat carrier medium provided in a first heat carrier medium circuit;
an operating material tank configured to hold a liquid operating material;
a second heat exchanger device configured to transfer heat between the first heat carrier medium provided in the first heat carrier medium circuit and energy storage material contained in the operating material tank;
a third heat exchanger device configured to transfer heat between the first heat carrier medium provided in the first heat carrier medium circuit and a second heat carrier medium provided in a second heat carrier medium circuit;
a heat pump system associated with the second heat carrier medium circuit;
a cooling heat exchanger device associated with the second heat carrier medium circuit for absorbing heat from air to be introduced into a vehicle interior flowing through the cooling heat exchanger device in a cooling operation of the heat pump system;
