Abstract
An integrated thermal transfer system is provided for transferring heat between a coolant and a refrigerant in an HVAC system to change a temperature of the coolant. Heat is then transferred between the coolant having a changed temperature and a device in need of thermal control, such as a battery. The system includes an evaporator having a refrigerant tank, where the refrigerant tank contains the refrigerant. A coolant tank is disposed adjacent and in thermal communication with the refrigerant tank, the coolant tank including an inlet and an outlet, where the coolant tank contains the coolant. The device is fluidly coupled to the inlet and the outlet of the coolant tank.
