The memory 1005 may also optionally be a storage device separate from the processor 1001 described above.
It will be appreciated by those skilled in the art that the configuration shown in fig. 1 is not limiting of the air conditioner and may include more or fewer components than shown, or may combine certain components, or may be a different arrangement of components.
As shown in fig. 1, an operating system, a network communication module, a user interface module, and an air conditioner control program may be included in the memory 1005 as one type of storage medium.
In the air conditioner shown in fig. 1, the network interface 1004 is mainly used for data communication with a network server; the user interface 1003 is mainly used for data interaction with a user; the processor 1001 and the memory 1005 in the air conditioner of the present invention may be disposed in the air conditioner, and the air conditioner invokes the air conditioner control program stored in the memory 1005 through the processor 1001 and executes the control method of the air conditioner provided in the embodiment of the present invention.
Based on the above hardware structure, an embodiment of the control method of the air conditioner of the present invention is presented.
Referring to fig. 2, fig. 2 is a flowchart illustrating a control method of an air conditioner according to a first embodiment of the present invention.
In this embodiment, the control method of the air conditioner includes the following steps:
step S10: and when the energy release loop is in cooling, acquiring the current indoor temperature and the set air outlet temperature of the air conditioner.
In this embodiment, the execution body of the embodiment is the air conditioner control device, which has functions of data processing, data communication, program running, and the like, and the air conditioner control device may be a computer device such as a tablet, a computer, or a server. Of course, other devices with similar functions may be used, and the implementation conditions are not limited thereto. For convenience of explanation, the present embodiment will be described taking an air conditioner control device as an example.
It should be noted that, the present cold storage air conditioner generally adopts an internal ice melting type ice storage scheme, and the scheme is that a low-temperature glycol aqueous solution (secondary refrigerant) produced by a water chilling unit is sent into a plastic pipe or a metal pipe in an ice storage tank (barrel) to enable water outside the pipe to be frozen. The ice storage tank can freeze more than 90% of water into ice. When melting ice, the glycol water solution with higher temperature flowing back from the air conditioner load end enters the ice storage tank, flows through the plastic or metal coil pipe to melt the ice outside the pipe, and the temperature of the glycol water solution is reduced and then is pumped back to the air conditioner load end for use. However, the heat exchange area of the inner ice melting is only the surface of the coil, so that the ice melting and cooling releasing speed of the inner ice melting is low, the current cold storage air conditioner cannot realize the rapid cooling function, and the requirement of the kitchen air conditioner for use at once cannot be met.
In order to solve the above problems, the embodiment uses an external ice melting mode to store cold, and detects the indoor environment temperature and the set air outlet temperature of the air conditioner in real time, and adjusts the air shield of the indoor unit according to the indoor environment temperature and the set air outlet temperature of the air conditioner, thereby realizing a rapid refrigeration function and meeting the demand of the kitchen air conditioner for instant use.
In order to make the technical scheme related to the implementation mode of each control method clearer, the invention firstly provides an air conditioner.
Referring to fig. 3 and 4, fig. 3 is a schematic structural view of an air conditioner according to an embodiment of the present invention; fig. 4 is a schematic structural view of an air conditioner according to an embodiment of the present invention, in which fig. 3 is a front view and fig. 4 is a bottom view.

The air conditioner has an energy storage mode and an energy release mode. In the energy storage mode, the wind wheel 12 is started to form air external circulation, and the air conditioner stores cold or heat into the energy storage unit through the energy storage loop and the air duct.

The energy release loop comprises a water inlet pipe 8, a water outlet pipe 9, an indoor unit 10 and a circulating pump 11.
Further, the energy storage mode includes a cold storage mode and a heat storage mode. In the cold accumulation mode, the system realizes the cold accumulation process that after the compressor 3 is started, the gaseous refrigerant is firstly condensed by the condenser 2 and then enters the water tank heat exchanger 7 for evaporation after passing through a throttling component (not shown in the figure) of the system, the evaporation process is to remove the heat of water in the water tank 6 and reduce the water temperature to the freezing point, the process leads the water to generate phase change and simultaneously stores the cold energy, and the process completes a complete cold accumulation process.
The energy release mode includes a cool release mode and a heat release mode. In the cooling mode, after an indoor fan is started in the cooling process, a circulating pump 11 is started to operate, the circulating pump 11 brings cooled cold water at the temperature of 0 ℃ of a water tank 6 to an indoor unit heat exchanger (not shown in the figure) through a water inlet pipe 8, then the cold energy is sent to the indoor unit through the fan (not shown in the figure), and returned water at the temperature of 5 ℃ of return water after later temperature rise returns to the water tank 6 through a water outlet pipe 9, so that the complete cooling process is completed.

As shown in fig. 9, an air conditioner control device according to an embodiment of the present invention includes:
and the detection module 10 is used for acquiring the current indoor temperature and the set air outlet temperature of the air conditioner when the energy release loop is in cooling.
It should be noted that, the present cold storage air conditioner generally adopts an internal ice melting type ice storage scheme, and the scheme is that a low-temperature glycol aqueous solution (secondary refrigerant) produced by a water chilling unit is sent into a plastic pipe or a metal pipe in an ice storage tank (barrel) to enable water outside the pipe to be frozen. The ice storage tank can freeze more than 90% of water into ice. When melting ice, the glycol water solution with higher temperature flowing back from the air conditioner load end enters the ice storage tank, flows through the plastic or metal coil pipe to melt the ice outside the pipe, and the temperature of the glycol water solution is reduced and then is pumped back to the air conditioner load end for use. However, the heat exchange area of the inner ice melting is only the surface of the coil, so that the ice melting and cooling releasing speed of the inner ice melting is low, the current cold storage air conditioner cannot realize the rapid cooling function, and the requirement of the kitchen air conditioner for use at once cannot be met.
In order to solve the above problems, the embodiment uses an external ice melting mode to store cold, and detects the indoor environment temperature and the set air outlet temperature of the air conditioner in real time, and adjusts the air shield of the indoor unit according to the indoor environment temperature and the set air outlet temperature of the air conditioner, thereby realizing a rapid refrigeration function and meeting the demand of the kitchen air conditioner for instant use.
