1. A device for controlling a compressor of a vehicle, the device comprising: a sensor module including a cabin temperature sensor detecting a cabin temperature of the vehicle, an outdoor temperature sensor detecting an outdoor temperature, an evaporator temperature sensor detecting an evaporator temperature of a cooling medium in an evaporator, a vehicle speed sensor detecting a vehicle speed, and a brake sensor detecting an operation of a brake pedal;an injector injecting a fuel for an engine of the vehicle;an air conditioning system including a condenser condensing and liquefying the cooling medium, an evaporator evaporating the liquefied cooling medium, the compressor compressing the cooling medium, a temperature control door controlling a temperature of air flowing into a cabin of the vehicle, an intake door selectively distributing an inner air or an outer air into the cabin of the vehicle, and a blower blowing the air to the intake door; anda controller controlling the injector and the air conditioning system,wherein the controller is configured to accumulate a cold air energy by increasing an operation of the compressor in a case that a speed-reducing condition occurs until the evaporator temperature reaches a first target temperature in the case that the speed-reducing condition occurs, the first target temperature being a temperature where the evaporator begins to be frozen,wherein the air conditioning system uses the accumulated cold air energy by decreasing the operation of the compressor in a case that a release condition occurs, andwherein the controller controls the temperature control door to raise the temperature of the air supplied to the cabin in a case that the detected evaporator temperature is lower than a second target temperature during increasing the operation of the compressor, andwherein the release condition is satisfied when the speed-reducing condition is not satisfied. 2. The device of claim 1, wherein the controller decreases the operation of the compressor until the evaporator temperature is higher than or equal to an allowable temperature in a case that the release condition occurs. 3. The device of claim 2, wherein the controller controls the temperature control door to lower the temperature of the air supplied to the cabin in a case that the evaporator temperature is higher than a second target temperature during decreasing the operation of the compressor. 4. The device of claim 3, wherein control of the temperature control door by the controller comprises control of the intake door through which the inner air or the outer air selectively flows in the cabin and control of blowing speed of the blower. 5. The device of claim 2, wherein the controller increases the operation of the compressor according to a target increasing rate of the operation of the compressor in a case that the evaporator temperature is higher than or equal to the allowable temperature. 6. The device of claim 5, wherein the controller increases the operation of the compressor until the operation of the compressor reaches a target operation of the compressor. 7. The device of claim 5, wherein the controller controls the temperature control door to lower the temperature of the air supplied to the cabin in a case that the evaporator temperature is higher than the second target temperature during increasing the operation of the compressor. 8. The device of claim 7, wherein control of the temperature control door by the controller comprises control of the intake door through which the inner air or the outer air selectively flows in the cabin and control of blowing speed of the blower.
