The invention belongs to the technical field of vehicle-mounted air conditioners and discloses an air conditioner intelligent quick cooling and energy saving control method. If it is detected that T<inner ring> is smaller than or equal to T<optimization>, and T<outer ring> is smaller than or equal to T<outer highest frequency>, operation is conducted normally; if it is detected that T<inner ring>is larger than T<optimization> and larger than T<set temperature>+delta T, and T<outer ring> is smaller than or equal to T<outer highest frequency>, the following steps are executed, where the following steps include that if the inner air gear is set to be a high air gear, an inner draught fan operates according to an ultra-high gear, a compressor operates according to the highest frequency f<highest>, and the temperature is reduced quickly; if the inner air gear is set to be a non-high air gear, the inner draught fan operates according to the set air gear; when it is detected that T<inner ring> is smaller than or equal to T<set temperature>+delta T and smaller than or equal to T<optimization>, or operation consumption time reaches t<quick>, the inner draught fan operates according to thehigh air gear, and the compressor operates according to the highest frequency f<highest>; and when it is detected that T<inner ring> is smaller than or equal to T<set temperature>+delta T and smallerthan or equal to T<comfortable>, operation is conducted normally. The problems that the temperature is reduced slowly, the comfort level is low, and energy cannot be saved under the condition that theinterior of a vehicle is high in temperature and stuffy after being exposed under the blazing sun are solved.
