Air conditioner intelligent quick cooling and energy saving control method

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of automobile air conditioners, and in particular relates to an intelligent rapid cooling and energy saving control method for an air conditioner. Background technique [0002] At present, the air conditioners used in passenger cars and urban buses and vehicle-mounted air conditioners are often encountered in actual use. Causes hot and stuffy conditions, often much hotter inside the car than outside. According to the big data research: in this case, after starting the vehicle, the driver and passengers are most concerned about the temperature drop in the car after starting the air conditioner, hoping to solve the temperature drop demand and noise demand, so as to quickly cool down and achieve comfort somatosensory. [0003] At present, there are three main forms of frequency control during the stable operation of air conditioners used in passenger cars and urban buses: [0004] The first is a common contr...

AI Technical Summary

Problems solved by technology

[0009] In view of the above-mentioned technical problems in the prior art, the purpose of the present invention is to provide a vehicle-mounted air conditioner such as an air conditioner for passenger cars and city buses, which takes into account the first power-on start-up operation process to quickly reduce the indoor temperature (in-vehicle temperature) to meet comfort requirements and The new intelligent control method of energy-saving control can solve the problems of rapid cooling, slow cooling, discomfort and non-energy saving in passenger cars, urban bus air conditioners and other vehicle-mounted air conditioners after exposure to the sun
