摘要： A waste heat utilization system may include an air conditioning circuit for air conditioning a vehicle interior of the electric vehicle, wherein a working medium may circulate in the air conditioning circuit, which may have arranged therein a compressor for compressing the working medium, a condenser for condensing the working medium, and an evaporator for evaporating the working medium. The system may also include a cooling circuit for cooling at least one of the electric motor and the battery, wherein a coolant may circulate in the cooling circuit, which may have arranged therein the electric motor in a first branch and the battery in a second branch fluidically connected in parallel with the first branch, a first heat exchanger for discharging heat from the coolant into surroundings of the waste heat utilization system, a first delivery device for driving the coolant in the cooling circuit, a first chiller via which heat may be transferrable from the first branch into the air conditioning circuit, and a second chiller via which heat may be transferrable from the second branch into the air conditioning circuit. The system may further include a heating circuit, in which a heating medium circulates, and in which a second delivery device for driving the heating medium and a second heat exchanger for giving off heat from the heating medium into the vehicle interior may be arranged. The condense may be an indirect heat exchanger via which heat is transferrable from the air conditioning circuit into the heating circuit.

摘要： An air-conditioning system for a motor vehicle may include at least two indirect heat exchangers through each of which both water and air is flowable. The water and the air may be fluidically separated from one another such that heat is transferable therebetween. The system may also include a warm water supply, a cold water supply, and at least two temperature-control devices each including a respective indirect heat exchanger of the at least two indirect heat exchangers. The warm and/or cold water supply may be in fluid communication with the at least two indirect heat exchangers. At least one indirect heat exchanger of the at least two indirect heat exchangers may communicate with the warm water supply and the cold water supply via an adjustable and controllable valve device such that a mixing ratio of a mixture of the warm water and the cold water introduced therein is adjustable.
