Justice.
Fig. 1 and Fig. 2 are please referred to, the control method of embodiment of the present invention is applied to air-conditioning system 100.Air-conditioning system 100
Including outdoor unit 10 and indoor unit 20.Outdoor unit 10 connects indoor unit 20.Refrigerant recycles between outdoor unit 10 and indoor unit 20.
In the present invention, air-conditioning system 100 is multi-online air-conditioning system 100, such as Three-pipe heat recovery multi-connected machine air-conditioning system 100.It is more
Online air-conditioning system 100 includes at least one outdoor unit 10 and two or more indoor units 20.Air-conditioning system shown in Fig. 2
100, it is merely meant that the main modular or component of air-conditioning system 100, do not make specifically the quantity of indoor unit 20 and outdoor unit 10
Limitation.
It is appreciated that air-conditioning system 100 includes pure refrigeration mode, pure heating mode and mixed mode.Air-conditioning system 100
Mixed mode includes main refrigeration mode and main heating mode.When air-conditioning system 100 is with the operation of pure refrigeration mode, indoor unit 20 is equal
Freeze.When air-conditioning system 100 is with the operation of pure heating mode, indoor unit 20 is heated.When air-conditioning system 100 is with mixed
When syntype is run, part indoor unit 20 freezes, and part indoor unit 20 heats.
Referring to Fig. 1, the control method of air-conditioning system 100 includes:
Step S12: acquisition outdoor temperature T simultaneously judges whether outdoor temperature T meets mixed-mode operations condition;
Step S14: if outdoor temperature T meets mixed-mode operations condition, it is greater than preset temperature threshold G in outdoor temperature T
When (T > G), air-conditioning system 100 is controlled with the operation of main refrigeration mode;
Step S16: when outdoor temperature T is not more than preset temperature threshold G (T≤G), air-conditioning system 100 is controlled with main system
Heat pattern operation.
The control method of the air-conditioning system 100 of embodiment of the present invention, controls air conditioner using the judgement of outdoor temperature T
System 100 is run with main heating mode or main heating mode, can avoid air-conditioning system 100 frequently in pure refrigeration mode or pure heating
Toggling between mode and mixed mode reduces the energy consumption of air-conditioning system 100, meets the demand of user.
It is appreciated that in the prior art, air-conditioning system when determining starting operational mode and carrying out operational mode switching,
Only consider that heating can need and freeze the variation that can be needed.For example, having refrigeration that can need after air-conditioning system starting and can needed without heating
When, air-conditioning system can be directly entered pure refrigeration mode.If in the operational process of air-conditioning system, if suddenly have heating can need and
Still there is refrigeration that can need at this time, air-conditioning system can be switched to mixed mode from pure refrigeration mode.For another example, after air-conditioning system starting,
Existing refrigeration need to can have again heating that can take, and air-conditioning system can be directly entered mixed mode.In the operational process of air-conditioning system,
If refrigeration can need to become zero and still have heating that can need at this time, air-conditioning system can be switched to pure heating mode from mixed mode.Energy
Need to change fastly will lead to air-conditioning system and frequently toggles between pure refrigeration mode or pure heating mode and mixed mode.Air-conditioning
System toggling between pure refrigeration mode or pure heating mode and mixed mode needs the compressor of outdoor unit standby so
Restart again afterwards, increases the energy consumption of air-conditioning system.
In embodiment of the present invention, in 100 starting up of air-conditioning system, acquires outdoor temperature T and judge outdoor temperature T
Whether mixed-mode operations condition is met.If outdoor temperature T meets mixed-mode operations condition, further according to outdoor temperature T
It is run with the size relation control air-conditioning system 100 of preset temperature threshold G with main refrigeration mode or main heating mode is run.If room
When outer temperature T is unsatisfactory for mixed-mode operations condition, controls air-conditioning system 100 and run with pure refrigeration mode or pure heating mode.
Since outdoor temperature T will not be changed greatly within a short period of time, mixed-mode operations condition is reasonably set, it can be to avoid air-conditioning
Frequent the toggling between pure refrigeration mode or pure heating mode and mixed mode of system 100, reduces air-conditioning system 100
Energy consumption.
Mixed-mode operations condition is the temperature range of mixed-mode operations comprising the first temperature threshold T1, the second temperature
Threshold value T2 and T1 is spent to the temperature range (T1, T2) between T2.When outdoor temperature T is less than the first temperature threshold T1, outdoor temp
Degree T is unsatisfactory for mixed-mode operations condition, then controls air-conditioning system 100 with the operation of pure heating mode, when outdoor temperature T is greater than the
When two temperature threshold T2, outdoor temperature T is unsatisfactory for mixed-mode operations condition, then controls air-conditioning system 100 with pure refrigeration mode
Operation.It is appreciated that mixed-mode operations condition can be configured according to the climate type of given area.In an example
In, the first temperature threshold T1 be -13 DEG C, -17 DEG C or -13 DEG C to -17 DEG C between temperature, second temperature threshold value T2 be 25 DEG C,
Temperature between 29 DEG C or 25 DEG C to 29 DEG C.Preferably, the first temperature threshold T1 is -15 DEG C, second temperature threshold value T2 is 27 DEG C.
Preset temperature threshold G is the temperature between 8 DEG C, 12 DEG C or 8 DEG C to 12 DEG C, preferably, preset temperature threshold G is 10 DEG C.
It should be noted that outdoor temperature T can be acquired by the outdoor temperature sensor of setting.In the present invention
In, i.e., it can need to be taken without heating again without refrigeration, the indoor unit 20 and outdoor unit 10 of air-conditioning system 100 are in standby shape
State.The refrigeration of each indoor unit 20 can need=indoor unit 20 several * (set temperatures of room temperature-indoor unit 20).Each
The heating of indoor unit 20 can need=indoor unit 20 several * (set temperature-room temperatures of indoor unit 20).
