The embodiment of first aspect present invention provides a kind of control method of air-conditioning system, is used for air-conditioning system, such as Fig. 1 Shown, the control method of the air-conditioning system includes: step 102, judges the time between current time and default unused time Whether difference is poor greater than preset time, if the time difference between current time and default unused time is poor greater than preset time, controls It makes the air-conditioning system to run with conventional operating mode, if the time difference between current time and default unused time is less than or equal to Preset time is poor, then reduces the power consumption of the air-conditioning system, makes the air-conditioning system with default low-power consumption mode operation.
The control method for the air-conditioning system that embodiment according to the present invention provides is used for air-conditioning system, such as multiple air conditioner Adjusting system, certainly, air-conditioning system are also possible to the common air-conditioning of conventional single-plicate.Specifically, the controlling party of the air-conditioning system Method includes whether to be greater than preset time the time difference for judging between current time and default unused time poor, and current by judgement It is poor whether the time difference between time and default unused time is greater than preset time, can judge that current time distance is default and close The machine time there are also how long, so as to preset the unused time in distance, to be greater than preset time poor, such as the default shutdown of distance When time is greater than five points of kinds, air-conditioning system is allowed to run according to normal operating mode, normally to be freezed or be heated, and It is poor less than or equal to preset time that distance presets the unused time, for example apart from when the default unused time being less than or equal to five points of kinds, reduces The power consumption of air-conditioning system so that air-conditioning system is run with low-power consumption mode, for example, allow compressor with low frequency operation and/ Or allow outdoor fan with low-power consumption modes such as slow-speed of revolution operations, it just can be reduced in advance empty before air-conditioning system shutdown in this way The power consumption of adjusting system just can reduce the heat remained in air conditioner indoor unit or cold in this way when air-conditioning system is really shut down Amount with energy saving, is mentioned with making full use of the residual temperature in air conditioner indoor unit and making full use of existing heat or cooling capacity in room The energy utilization rate of high air-conditioning system.In addition, air-conditioning system is in normal refrigeration, the condensed water of generation is more, but in shutdown It is preceding to allow air-conditioning system with default low-power consumption mode operation in advance, the condensed water generated on indoor heat exchanger can be reduced, but at this time Indoor fan is still operating, and substantially can take away the condensed water of generation, and therefore, this kind of structure can also be in refrigeration shutdown Before, indoor heat exchanger is dried, thus prevents and breeds bacterium on indoor heat exchanger.
Wherein, the power consumption for here presetting at low-power consumption mode is less than power consumption of air-conditioning system when running with conventional operating mode, Specifically, power consumption of the air-conditioning system when low-power consumption mode is run can be specifically determined according to the actual situation, it can be according to practical need Determine the compressor of air-conditioning system, the running parameter in low energy mode operation such as outdoor fan, indoor fan, so as to energy Enough power consumptions for reducing air-conditioning system on the whole.
Fig. 2 shows embodiment according to the present invention provide air-conditioning system control method another flow diagram, Specifically, the embodiment method specifically includes the following steps:
Step 202, judge preset time of each air conditioner indoor unit of the air-conditioning system after the default unused time Whether shutdown command is received in range, if each air conditioner indoor unit of the air-conditioning system is pre- after the default unused time If receiving shutdown command in time range, then control the air-conditioning system and shut down immediately, if each sky of the air-conditioning system It adjusts indoor unit not receive shutdown command in the preset time range after the default unused time, then controls the air-conditioning system It is run with conventional operating mode；
Step 204, judge preset time of each air conditioner indoor unit of the air-conditioning system after the default unused time Whether shutdown command is received in range, if each air conditioner indoor unit of the air-conditioning system is pre- after the default unused time If receiving shutdown command in time range, then control the air-conditioning system and shut down immediately, if each sky of the air-conditioning system It adjusts indoor unit not receive shutdown command in the preset time range after the default unused time, then controls the air-conditioning system It is run with conventional operating mode；
Step 206, the actually powered off time for recording the air-conditioning system, again according to the actually powered off time of record Determine the default unused time.
Wherein, in step 202, whether it is greater than by the time difference judged between current time and default unused time pre- It if the time difference, can judge also how long current time distance presets the unused time, be closed so as to be preset in distance It is poor that the machine time is greater than preset time, for example apart from when presetting the unused time greater than five points of kinds, allows air-conditioning system according to normal work Operation mode operation, normally to be freezed or be heated, and it is poor less than or equal to preset time in the distance default unused time, such as When distance presets the unused time less than or equal to five points of kinds, the running frequency of compressor can be reduced, to reduce the power consumption of air-conditioning system, Thus with realizing energy-efficient mesh, meanwhile, the mode of windscreen can also be reduced to drop by way of reducing the revolving speed of outdoor fan The power consumption of low latitude adjusting system, thus with realizing energy-efficient mesh.But preferably, can simultaneously by reduce compressor running frequency with And the mode of the revolving speed of outdoor fan reduces the power consumption of air-conditioning system, so that with realizing energy-efficient mesh, air-conditioning can be made in this way The overall power of system declines, it is thus possible to keep the energy-saving effect of air-conditioning system more significant.
Wherein, in step 202, when air-conditioning system is run with low-power consumption mode, the working frequency of compressor can be according to reality Border needs to set, but when air-conditioning system is run with low-power consumption mode, the working frequency of compressor is preferably arranged in 20HZ-40HZ Left and right, certainly, what the working frequency of compressor can also be arranged according to actual needs is greater than 40HZ or is less than 20HZ.
Wherein, in step 202, when air-conditioning system is run with low-power consumption mode, the working speed of outdoor fan can basis Actual needs setting, but when air-conditioning system is run with low-power consumption mode, the working speed of outdoor fan is preferably arranged in 100r/ Min-500r/min or so.
Wherein, in step 202, the value of preset time difference can be set according to actual needs, but preset time difference cannot It is excessive, the excessive overlong time that will lead to air-conditioning system and carry out low power operation in advance, so as to cause air-conditioning system refrigeration or Heating capacity is insufficient, thus can reduce user experience, meanwhile, preset time difference can not be too small, and the too small air-conditioning system that will lead to exists The time of low power operation is too short before shutdown, to not have the residual temperature and indoor residual temperature made full use of in air conditioner indoor unit Purpose, thus the energy-saving effect of air-conditioning system can be reduced.It is therefore preferred that the preset time difference can be arranged in 5min- Between 10min, just air-conditioning system can be made to carry out low-power consumption mode in the 5min-10min before the default unused time in this way Operation, can prevent low-power consumption mode runing time too long in this way, and can fully utilize the residual temperature of indoor unit, to save The energy reduces the power consumption of product.
