Air conditioning lack of fluoride protection method and apparatus

The present invention discloses an air conditioning method and apparatus protection lack of fluoride. Wherein, the air conditioning lack of fluoride protection method comprising: a first temperature of the first evaporator tube temperature and air conditioner evaporator temperature detecting air conditioner in which the indoor environment difference, wherein the temperature of the first evaporator tube evaporator in the first evaporator tube temperature time; a first predetermined condition is satisfied is determined first temperature difference; a first evaporator tube temperature detector and the second air conditioner evaporator temperature of the second temperature difference between the evaporator tube, wherein the second evaporator tube temperature of air conditioner evaporator temperature of the evaporator tubes at a second time point; a second predetermined condition is satisfied second temperature difference is determined; and if the temperature difference is judged that the first condition satisfies a first predetermined temperature difference satisfy the first and the second two pre-conditions, the execution control air conditioning lack of fluoride protection. By the present invention, to solve the problem of the related art compressor is liable to cause excessive winding temperature.
