Embodiment Construction

[0023] figure 1 An air conditioning system 2 according to a first embodiment of the invention is shown.

[0024] The air conditioning system 2 according to the invention has two cooling circuits 4 and 6 , the cooling circuit 4 serving to cool the drive motor 8 , and the cooling circuit 6 being designed as an air conditioning system cooling circuit and simultaneously serving to cool the battery modules 10 . The two cooling circuits 4 , 6 discharge waste heat via a common cooler 20 into the surroundings.

[0025] The battery module 10 has a thermostatic circuit 12 in which the coolant is pumped by means of a pump 14 through a heat exchanger 16 which is thermally coupled to the air-conditioning system cooling circuit 6 by means of a cooling circuit 50 . In addition, a heater 18 is provided. Depending on the temperature of the battery module 10 , heat can be withdrawn from the thermostatic circuit 12 by means of a heat exchanger 16 or fed in by means of a heater 18 in order to b...

Abstract

An air-conditioning system (2, 102)is provided for an automobile comprising an interior air-conditioning module (38, 138), which can be connected in a heat-transporting manner to at least two coolant-carrying cooling circuits of the automobile via valves (32, 52, 132, 152)(e.g., controllable or adjustable valves). A controller (64, 164) is also provided that is configured to control the valves (32, 52, 132, 152)in such a manner that those cooling circuits (4, 6, 104, 106)having the higher coolant temperature can be connected in a heat-transporting manner to the interior air-conditioning module. A method is also provided for operating an air-conditioning system (2, 102).

Description

technical field [0001] The invention relates to an air-conditioning system with at least two coolant-carrying cooling circuits and an interior air-conditioning module and a method for operating the air-conditioning system. Background technique [0002] Air conditioning systems are known in the prior art. Almost all cars have passenger compartment heating to keep the passenger compartment at a comfortable temperature and to keep the windows, especially the windshield, from clouding from condensation. Cars often also have air conditioning, which cools the interior. [0003] In a conventional car, the air conditioning system obtains the necessary thermal energy from the waste heat of the internal combustion engine. In the case of high-efficiency internal combustion engines, especially modern diesel engines, and / or in the case of large interior volumes, heaters are sometimes provided in order to rapidly heat the interior. [0004] Electric vehicles, due to their operating pri...
