1. A system comprising:
- a first heat exchanger;
an expansion device in direct fluid communication with the first heat exchanger;
a pumping device in fluid communication with the first heat exchanger; and
a valve receiving a fluid from the pumping device and movable between a first position allowing the fluid through a first flow path and a second position to allow the fluid to flow through a second flow path,a second heat exchanger;
an energy storage device in heat transfer relation to the second heat exchanger;
whereinwhen the valve is in the first position, the first flow path extends from the valve through the first heat exchanger and from the first heat exchanger through the second heat exchanger; and
when the valve is in the second position, the second flow path extends from the valve, through the second heat exchanger bypassing the first heat exchanger.

Abstract
A system may include a first heat exchanger, a pumping device, and a valve. The pumping device may be in fluid communication with the first heat exchanger. The valve may receive a fluid from the pumping device and may be movable between a first position allowing the fluid through a first flow path and a second position to allow the fluid to flow through a second flow path. The first heat exchanger may be in heat transfer relation with an energy storage device such that heat may be extracted from the energy storage device when the valve is in the first position. Heat may be transferred from the first heat exchanger to the energy storage device when the valve is in the second position.

11. A system for a vehicle, the vehicle having a cabin and a battery, the system comprising:
-
a first fluid path including a first heat exchanger providing a cooling effect to air within the cabin; an expansion device in direct fluid communication with the first heat exchanger; and a second fluid path including a second heat exchanger and a valve, the second heat exchanger being in heat transfer relation with the battery, the valve being movable between a first position allowing fluid at a first temperature to flow through the second heat exchanger to extract heat from the battery and a second position allowing fluid at a second temperature to flow through the second heat exchanger to transfer heat from the fluid to the battery;
whereinwhen the valve is in the first position, fluid flows from the valve to the first heat exchanger and from the first heat exchanger to the second heat exchanger; and when the valve is in the second position, fluid flows from the valve to the second heat exchanger bypassing the first heat exchanger. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
