Abstract
A temperature control system to be installed in an electric vehicle includes a water circuit, a coolant circuit, a radiator, a heat exchanger, a water pump, and a controller. The water circuit circulates cooling water to cool an electric device. The coolant circuit circulates a coolant to control a temperature of a cabin or battery of the electric vehicle. The radiator is disposed in the water circuit. The heat exchanger is disposed in the coolant circuit and receives heat released from the radiator through cooling air delivered from the radiator. The water pump regulates a flow rate of the cooling water circulating in the water circuit. The controller increases the number of rotations of the water pump to a greater value in a condition where an increase in temperature of the cabin or the battery is requested than in a normal condition where the increase in temperature is not requested.
