In order to solve the above problems, this embodiment provides a control method for an air conditioner, where the air conditioner includes multiple air supply modes, multiple dehumidification modes, and multiple bacteriostatic modes, and the control method includes: and in the process of refrigerating operation of the air conditioner, determining the current indoor heat and humidity load working condition according to the acquired indoor temperature value and indoor humidity value, selecting a corresponding air supply mode, dehumidification mode and bacteriostasis mode according to the determined heat and humidity load working condition, and controlling the air conditioner to operate according to the selected air supply mode, dehumidification mode and bacteriostasis mode.

And determining the air supply mode, the dehumidification mode and the bacteriostasis mode corresponding to the current indoor heat and humidity load working condition in the preset corresponding relation according to the preset corresponding relation between different heat and humidity load working conditions and different air supply modes, dehumidification modes and bacteriostasis modes.
This embodiment combines air supply mode, dehumidification mode and antibacterial mode and indoor damp and hot operating mode, selects corresponding air supply mode, dehumidification mode and antibacterial mode according to indoor damp and hot operating mode condition. The air conditioner controller stores preset corresponding relations of different damp and hot working conditions and different air supply modes, dehumidification modes and bacteriostasis modes, and after the current indoor damp and hot working conditions are determined, the air supply modes, the dehumidification modes and the bacteriostasis modes corresponding to the current damp and hot working conditions can be found according to the preset corresponding relations. It should be noted that the current indoor damp-heat working condition can be represented according to the magnitude of the temperature difference Δ tin and the set temperature difference t1, and the comparison result of the humidity difference Δ din and the set humidity difference d 1.
The air supply system comprises a plurality of air supply modes, namely an upper air supply mode and a lower air supply mode, wherein the upper air supply mode and the lower air supply mode are used for controlling an upper air outlet and a lower air outlet of the air conditioner to simultaneously supply air in the upper air supply mode and the lower air supply mode, and the upper air outlet mode only controls the air outlet of the upper air outlet of the air conditioner; the air outlet implementation of the cooling mode of the air conditioner is shown in figure 2,
when the air conditioner is started for refrigeration, the temperature sensor is used for detecting and recording the current indoor temperature tin of a room in real time, the set temperature tc of the air conditioner, and delta tin is specified as the difference value between the current indoor temperature tin and the set temperature tc of the air conditioner.
1) When the difference delta tin between the indoor temperature tin and the set temperature tc of the air conditioner is larger than t1, the indoor heat load is larger, the indoor temperature is higher, the air conditioner needs to refrigerate quickly, and indoor quick cooling is achieved by controlling the upper air inlet and the lower air outlet to supply air simultaneously.
2) When the difference value delta tin between the indoor temperature tin and the set temperature tc of the air conditioner is smaller than or equal to t1, the indoor heat load is smaller, the indoor temperature is close to the set temperature of the air conditioner, cold air is not directly blown only by opening the upper air inlet to supply air, cold discomfort caused by adhesion of the cold air to the ground can be reduced, and the indoor heat comfort level can be improved.
The multiple dehumidification mode is including cooling dehumidification mode and non-cooling dehumidification mode, refrigerates through control air conditioner in the cooling dehumidification mode and dehumidifies, heats through control air conditioner earlier in the non-cooling dehumidification mode and carries out the dehumidification.
Specifically, the implementation of the dehumidification mode of the air conditioner mainly includes two dehumidification modes, one is a conventional refrigeration dehumidification mode, and is not substantially different from the refrigeration of the air conditioner, as shown in fig. 3, both are cooling and dehumidification processes (1 → 2), that is, the temperature of air is reduced after passing through an indoor heat exchanger of the air conditioner, and water vapor in the air is liquefied into condensed water and discharged outdoors, so that the humidity of the indoor air is reduced. The other is a non-cooling dehumidification mode, as shown in fig. 3, which is different from the conventional refrigeration dehumidification mode in that a (2 → 3) heating process, i.e. a process of reheating the air cooled by the evaporator, is added, so that the temperature of the air cooled in the dehumidification process is raised again, and the temperature of the indoor air is ensured to maintain a relatively stable state. The present embodiment provides two selectable different dehumidification modes according to the heat and humidity load in the room, as shown in fig. 4, wherein the dehumidification mode 1 is that the air conditioner starts the normal refrigeration dehumidification mode, and the dehumidification mode 2 is that the air conditioner starts the non-cooling dehumidification mode.
The multiple antibacterial modes comprise an electric heating antibacterial mode and a heating antibacterial mode, wherein the electric heating antibacterial mode is used for controlling the electric heating module to heat and controlling the inner fan to rotate forwards and backwards firstly, and the heating antibacterial mode is used for controlling the air conditioner to heat.
Specifically, in the air-conditioning refrigeration and dehumidification process, the indoor heat exchanger is easy to generate condensed water on the surface of the indoor heat exchanger due to relatively low temperature, and if the indoor heat exchanger cannot be cleaned in time, bacteria and mold can be bred, peculiar smell is generated, and the indoor air quality is further influenced. The existing air conditioner bacteriostasis mode mainly includes means such as electric heating, fan reversal, heating drying and degerming equipment, but the degerming equipment easily causes the cost increase of the air conditioner, so this embodiment provides two different bacteriostasis modes according to the indoor heat and humidity load and combining the existing bacteriostasis means, as shown in fig. 5.
The bacteriostatic mode 1 is a bacteriostatic mode of starting electric heating and reversing an inner fan, the bacteriostatic mode 2 is a bacteriostatic mode of converting heating and drying, and the converting heating mode relates to starting and stopping of components such as an air conditioner compressor, a four-way reversing valve and the like, so that the relative energy consumption is large, and the bacteriostatic mode 1 is preferentially selected under the same condition. The specific implementation mode of the bacteriostatic mode is as follows:
the bacteriostasis mode 1: and starting an electric heating device of the air conditioner, and simultaneously opening an inner fan to blow air firstly, and then reversely blowing the air to the indoor heat exchanger by the inner fan.
And (3) a bacteriostatic mode 2: after refrigeration and dehumidification, the air conditioner changes the heating mode, and simultaneously opens the upper air inlet and the lower air inlet to carry out drying and bacteriostasis treatment.
The air conditioner of this embodiment integrally controls the cooling air supply mode, the dehumidification mode and the bacteriostasis mode according to the indoor heat and humidity load working condition, for example, as a control logic diagram shown in fig. 6, in the air conditioner cooling operation process, the current indoor temperature tin and the current humidity din are detected and recorded in real time through a temperature sensor and a humidity sensor, the set temperature tc and the humidity dc of the air conditioner are obtained at the same time, Δ tin is specified as the absolute value of the difference between the current indoor temperature tin and the set temperature tc of the air conditioner, and Δ din is the absolute value of the difference between the current indoor humidity din and the set humidity dc of the air conditioner.
Firstly, judging the relationship between the current indoor humidity and the set humidity of the air conditioner:
(1) When the humidity difference delta din is larger than the set humidity difference d1 and the temperature difference delta tin is larger than the set temperature difference t1, determining that the current indoor heat load and humidity load are large, selecting an air supply mode of the air conditioner as an up-and-down air supply mode, a dehumidification mode as a non-cooling dehumidification mode and a bacteriostasis mode as an electric heating bacteriostasis mode.
Specifically, if the difference between the current indoor humidity din and the set humidity dc of the air conditioner is greater than d1, and the difference between the indoor temperature tin and the set temperature tc of the air conditioner is greater than t1, it indicates that the indoor heat and humidity loads are relatively large, and the corresponding air treatment process is as shown in fig. 7 (6 → c). Because the indoor heat load is relatively large, an air supply mode of simultaneously blowing air up and down is selected, and cold air is simultaneously supplied through an upper air inlet and a lower air inlet to realize indoor rapid cooling; because the indoor humidity load is relatively large, the air conditioner can be accompanied with the great reduction of the indoor temperature in the process of refrigeration and dehumidification, and in order to ensure the indoor comfort, a non-cooling dehumidification mode is selected; in addition, because the indoor heat and humidity load is large, the surface of the indoor heat exchanger can generate a large amount of condensed water due to relatively low temperature, the reheating process is performed in the non-cooling dehumidification process, the air temperature is not too low, the antibacterial mode 1 is selected preferentially, the condensed water is heated and dried by opening the electric heating device of the air conditioner, the inner fan is opened simultaneously, the air channel is blown firstly, and then the fan is reversely blown to the indoor heat exchanger.
(2) And when the humidity difference delta din is larger than the set humidity difference d1 and the temperature difference delta tin is smaller than or equal to the set temperature difference t1, determining that the current indoor heat load is small and the current indoor humidity load is large, selecting an air supply mode of the air conditioner as an upper air supply mode, selecting a dehumidification mode as a cooling dehumidification mode and selecting a bacteriostatic mode as a heating bacteriostatic mode.
Specifically, if the difference between the current indoor humidity din and the set air conditioner humidity dc is greater than d1, and the difference between the current indoor temperature tin and the set air conditioner temperature tc is less than or equal to t1, it indicates that the indoor heat load is relatively small and the indoor humidity load is relatively large, and the corresponding air handling process is shown in fig. 7 (7 → c). Because the indoor heat load is relatively small, the air supply mode of single upper air outlet is selected, energy consumption waste caused by cold air accumulating on the ground is avoided, and cold air is not blown directly; although the indoor humidity load is relatively large and the heat load is relatively small, the temperature reduction brought by the air conditioner in the process of refrigeration and dehumidification does not result in too large indoor temperature reduction, and the influence on indoor heat comfort is relatively small, so that a conventional refrigeration and dehumidification mode is selected; because the indoor moisture load is great relatively heat load relatively less, probably still need extra dehumidification after the air conditioner refrigeration process, can further lead to indoor heat exchanger surface to produce a large amount of comdenstions water, need select antibacterial mode 2 this moment, the air conditioner changes the heating mode, opens upper and lower wind gap simultaneously, carries out dry antibacterial treatment, realizes disinfecting fast.
(3) And when the humidity difference delta din is judged to be less than or equal to the set humidity difference d1 and the temperature difference delta tin is larger than the set temperature difference t1, determining that the current indoor heat load is large and the current indoor humidity load is small, selecting the air supply mode of the air conditioner as an up-down air supply mode, selecting the dehumidification mode as a cooling dehumidification mode, and selecting the bacteriostasis mode as any one of a heating bacteriostasis mode or an electric heating bacteriostasis mode.
