A cold engine lockout CELO method is carried out when cooling water of an engine is not sufficiently warmed upon the startup of a vehicle in the winter according to default levels, wherein the default levels are divided into a total default level, a partial default level and a control level according to inside and outside air temperatures.

Celo method for vehicle

An air conditioner includes a thermoelectric device, and a first line with a first fluid therein. The first line is configured such that the first fluid can exchange heat with a first surface of the thermoelectric device, and configured to discharge the fluid to a space. A second line has a second fluid therein. The second line is configured such that the second fluid can exchange heat with a second surface of the thermoelectric device, and pass through a heat sink to further exchange heat. A control unit supplies electricity to the thermoelectric device such that the first surface absorbs heat in a cooling mode and the second surface absorbs heat in a heating mode. The control unit also controls a flow rate of the second fluid, such that the flow rate is higher in the cooling mode than in the heating mode.
