Two information in S202 are sent to specified server (database clothes by cellular network by S203, communication module Business device);
S204, the information that server receives communication module transmission obtain the local following weather forecast number by internet channel According to;
S205, server send the data of weather forecast of acquisition in communication module;
S206, communication module return to the information received into the controller of air conditioner;
S207, controller start T0 backward at the time of interception corresponding to compressor dwell time T according to data of weather forecast All data of the weather forecast that=6h is included;
The data (data in the following T0) of interception are divided into n points, define every equal part and be recorded as F1 ... Fk ... by S208 Fn.Every part of data processing is obtained into its average value, i.e., the average of every equal part are as follows: t1 ... tk ... tn;It defines k to take [2, n], n is extremely It is less 2;
S209 judges to detect tk-t (k-1) > 0, if so, executing step S210, otherwise, executes step S211;
S210, reservation electric heating unlatching at the time of waiting subregions Fk to correspond to;
S211, reservation electric heating closing at the time of waiting subregions Fk to correspond to;
S212 judges whether k=n, if so, the S202 that gos to step, otherwise, go to step S209.
It can be seen that from the above description, in the present invention, portion is provided with the communication mould for network communication in the air conditioner Block, can with the database server connection communication comprising weather data, also, the default compressor of air conditioner time out of service when Between threshold value.When the cooler compressor time out of service being more than the first preset time threshold, pass through the communication module and data Library server establishes connection, and transmission includes solicited message to the database server, and having time request is carried in solicited message The position request information of information and air-conditioning region is establishing connection with data server and is receiving the required weather of return After forecast data, using the data of weather forecast as air conditioner be in the standby state compressor whether need it is electrically heated according to According to.This control program, which efficiently solves air conditioner in the prior art and is in the standby state compressor, still needs to a large amount of electric heating The problem for causing compressor of air conditioner stand-by power consumption big reduces the electric heating opening time under air-conditioner standby state, decreases energy consumption.
