Beschreibung
Zusammenfassung:	A vehicle temperature control system includes: a first temperature control circuit; a second temperature control circuit; a heat exchanger in which heat exchange between a first temperature control medium and a second temperature control medium is performed; and a control device. The control device is capable of controlling a carrier frequency and a flow rate control valve of the second temperature control circuit based on the temperature of the first temperature control medium detected. In a case where the temperature of the first temperature control medium is lower than a predetermined value, the control device is configured to set the carrier frequency to be lower and controls the flow rate control valve such that the flow rate to a second branch flow path is smaller, as compared with a case where the temperature of the first temperature control medium is equal to or higher than the predetermined value.
