Referring to fig. 1, a schematic flow chart of a constant temperature dehumidification control method of an air conditioning system according to an embodiment of the present invention is shown.
The embodiment of the invention provides a constant temperature dehumidification control method of an air conditioning system, which comprises the following steps of S11 to S14:
s11, responding to a dehumidification instruction sent by a user, and acquiring the outdoor environment temperature; wherein, the dehumidification command comprises a dehumidification demand parameter.
The user can set the dehumidification demand parameters and send out the dehumidification command through a remote controller or a mobile phone and other equipment.
Specifically, the dehumidification demand parameters include an air quantity demand parameter and an air deflector position demand parameter.

In specific implementation, the first preset time and the target range may be set according to actual conditions of the air conditioning system, and are not limited herein, optionally, the first preset time is 10 minutes, and the target range is 9-11 ℃.
Optionally, referring to fig. 2, the step S13 specifically includes:
s131, after a first preset time, acquiring the real-time temperature of the indoor coil pipe, and jumping to the step S132;
s132, judging whether the real-time temperature of the indoor coil is smaller than the minimum value of the target range, if so, jumping to the step S133, and if not, jumping to the step S134;
s133, controlling the opening of the electronic expansion valve to increase according to a preset first valve step, obtaining the real-time temperature of the indoor coil again after a third preset time, and jumping to the step S132;

s16, acquiring indoor real-time temperature at preset time intervals, and controlling the air conditioning system to perform dehumidification treatment according to the target running state parameter or preset adjustment parameter based on the magnitude relation between the indoor real-time temperature and a preset temperature threshold value; the preset adjusting parameters comprise a minimum compressor running frequency parameter and a maximum air quantity parameter.
Acquiring indoor real-time temperature at preset time intervals, and judging the size relation between the indoor real-time temperature and a preset temperature threshold value; when the real-time indoor temperature is lower than a preset temperature threshold value, the refrigerating effect is over-strong, and at the moment, the air conditioning system is controlled to carry out dehumidification treatment according to the minimum compressor operation frequency parameter and the maximum air quantity parameter, so that the refrigerating capacity is reduced, the indoor ventilation frequency is increased, the dehumidification uniformity is realized, and the dehumidification effect is further improved; when the real-time indoor temperature is higher than the preset temperature threshold value, the dehumidification state is good, and the air conditioning system can continue dehumidification according to the target operation state parameters. It can be understood that the judgment of the size relation between the indoor real-time temperature and the preset temperature threshold value is carried out at preset time intervals, so that the dehumidification state can be monitored in time while the stable operation of the air conditioning system is ensured.
In specific implementation, the preset time interval may be set according to an actual condition of the air conditioning system, and is not limited herein, and optionally, the preset time interval is 5 minutes.
