A system for controlling temperature of an energy store in a motor vehicle may include a coolant circuit in which a coolant may be flowable and into which the energy store may be incorporated in the thermally conductive manner, a refrigerant circuit in which a refrigerant may be flowable and including a refrigerant compressor, a flat tube condenser, and a receiver dryer, which may be secured in the flat tube condenser, and a refrigerant evaporator connecting the coolant circuit and the refrigerant circuit. Heat between the coolant and the refrigerant may be transferrable in the refrigerant evaporator. The system may be secured in a housing. A large area of the flat tube condenser, through which air may be flowable, and the receiver dryer, which may be secured in the flat tube condenser, may have an operating angle of greater than 5° and smaller than 90° with respect to an operating horizontal plane, wherein the operating angle may be selected in such a way that dimensions of the system may be adapted to desired values and the system may be designed in a more compact manner.
