Description

Technical Field

[0001] The present invention belongs to the technical field of air conditioners, and particularly relates to a temperature rising and falling control method based on intelligent interconnection. Background Art

[0002] With the use of various intelligent interconnected home appliances, intelligent interconnected home appliances including intelligent air conditioners, televisions, windows, curtains, electric lights, etc. have entered thousands of households. Users can control various smart home appliances through voice, actions, portable terminals, etc. At the same time, various home appliances are also interconnected and controlled with each other.

[0003] From three aspects:

[0004] Although intelligent interconnected home appliances can be controlled through voice, actions, portable terminals, etc., human participation is still required, and users need to issue instructions, so the intelligence needs to be further improved. The ideal result is that home appliances can automatically give the optimal solution by obtaining information such as the environment and customers, and automatically turn on and execute the solution. In this way, no user operation is required and the optimal effect is achieved.

[0005] At present, rapid cooling and heating of air conditioners are still controlled from the air conditioner equipment itself (and often in the way that users need to set super cooling or super heating through the remote control) to achieve the purpose of rapid temperature rising and falling in the room. In this way, the effect of temperature rising and falling is limited and the speed is slow. The direct heat exchange and radiative heat exchange values through windows and walls with the outside world are very large. If this part of the loss can be reduced, the indoor temperature rising and falling speed will be greatly improved, and the actual power consumption of the air conditioner will be greatly reduced.

[0006] The heat loss through radiative heat exchange is huge.

[0007] The human body exchanges heat with the surrounding environment through three ways: convection, radiation, and evaporation, and heat conduction can be ignored.

[0008] Convective heat transfer: The air temperature determines the convective heat transfer temperature difference between the human body surface and the environment, thus affecting the convective heat transfer amount. However, the indoor wind speed is small, and the convective heat transfer amount accounts for 30% of the heat dissipated by the human body;

[0009] Radiative heat transfer: Radiative heat transfer accounts for 50% of the heat dissipated by the human body. Radiative heat transfer is the heat transfer process between two objects with different temperatures and not in contact with each other through electromagnetic waves. All objects in nature are constantly emitting radiant heat into space, and at the same time, constantly absorbing the radiant heat emitted by other objects. The radiative heat transfer between two objects is related to the emissivity of the object itself and the temperature difference on the object surface. The greater the temperature difference between two objects, the greater the radiative heat transfer.

[0010] Heat transfer between the human body and the environment mainly occurs through convection and radiation, and conduction can be basically ignored (the thermal conductivity of air is very low). Under ordinary indoor climate conditions, the surface temperature of the human body is higher than the average radiant temperature of the environment, and the indoor wind speed is generally small. Therefore, the radiant heat dissipation can account for about 50% of the total heat dissipation, the convective heat dissipation is about 30%, and the rest is evaporative heat dissipation.

[0011] Therefore, thermal radiation has a great impact on the heat dissipation of the human body. Not only for the human body, but also for indoor objects and indoor temperature, the principle is the same. As long as the temperature of the human body surface is inconsistent with the surrounding surface temperature, radiation heat transfer will occur between the human body and the environment. This is why the body feels completely different in summer and winter when the indoor temperature is the same at 20°C. In summer, the temperature of the wall and window is very high, while the human body temperature is low. The human body will receive a large amount of thermal radiation from the wall and window and feel hot. Similarly, indoor objects will all receive thermal radiation from the wall and window, and more cooling capacity is required to maintain the same indoor temperature. In winter, the temperature of the wall and window is very low, while the human body temperature is high. The human body will lose a large amount of heat through thermal radiation and be absorbed by the wall and window, feeling cold. More heat is required to maintain the same indoor temperature. If the radiation heat transfer between the human body and indoor objects and the wall and window can be reduced, the comfort of the human body and the speed of indoor temperature rise and fall can be greatly improved, and the power consumption of the air conditioner can be reduced. Summary of the Invention

[0013] In order to achieve the above object, the present invention adopts the following technical solutions:

[0014] A temperature rise and fall control method based on intelligent interconnection, comprising the following steps:

[0015] Step 1: Set the air conditioner temperature as T, the indoor environment temperature as T1, the human body temperature as T2, and the wall temperature as T3; the operation duration of the rapid temperature rise and fall mode is h; the indoor brightness is N; the temperature difference between the air conditioner set temperature T and the indoor environment temperature T1 is Δt1; the temperature difference between the human body temperature T2 and the wall temperature T3 is Δt2;

[0016] Step 2: Determine whether it is cooling or heating;

[0017] If: the determination result is cooling, then execute Step 3:

[0018] Or if the determination result is heating, then execute Step 4:

[0019] Step 3: Determine whether Δt1 is greater than the cooling preset value ΔT1 and Δt2 is greater than the cooling preset value ΔT2;

[0020] If: the determination result is that Δt1 is greater than the refrigeration preset value ΔT1, and Δt2 is greater than the refrigeration preset value ΔT2, then step 5 is executed;

[0021] Or if the determination result is that Δt1 is less than or equal to the refrigeration preset value ΔT1, and Δt2 is less than or equal to the refrigeration preset value ΔT2, then normal control operation is performed;

[0022] Step 4: Determine whether Δt1 is greater than the heating preset value ΔT1', and Δt2 is greater than the heating preset value ΔT2';

[0023] If: the determination result is that Δt1 is greater than the heating preset value ΔT1', and Δt2 is greater than the heating preset value ΔT2', then step 5 is executed; or if the determination result is that Δt1 is less than or equal to the heating preset value ΔT1', and Δt2 is less than or equal to the heating preset value ΔT2', then normal control operation is performed;

[0024] Step 5: Run the rapid temperature rise and fall mode;

[0025] Step 6: Determine whether the exit condition is satisfied;

[0026] If: the determination result is that the exit condition is satisfied, that is, the rapid temperature rise and fall mode is exited, and the user is informed by voice that the rapid temperature rise and fall mode has been exited and enter normal control operation;

[0027] Or if the determination result is that the exit condition is not satisfied, continue to run the rapid temperature rise and fall mode.

[0028] Preferably, the exit conditions include:

[0029] (1) Δt1 is less than the refrigeration preset value ΔT1, or Δt2 is less than the refrigeration preset value ΔT2, and the rapid temperature rise and fall mode is automatically exited; Δt1 is less than the heating preset value ΔT1', or Δt2 is less than the heating preset value ΔT2', and the rapid temperature rise and fall mode is automatically exited;

[0030] (2) The operation duration h of the rapid temperature rise and fall mode is greater than the preset value H, and the rapid temperature rise and fall mode is automatically exited;

[0031] (3) The user exits the rapid temperature rise and fall mode through voice or remote control.

[0032] The beneficial technical effects brought by the present invention:

[0033] The present invention obtains data on the indoor environmental temperature T1, the human body temperature T2, and the wall temperature T3 through an air conditioner temperature sensor, and controls the intelligent interconnection of the entire house through the interconnection with intelligent windows, intelligent curtains, and intelligent lights to achieve the optimal temperature increase and decrease effect. It also notifies the user through voice. When the exit condition is met, it automatically exits the rapid temperature increase and decrease mode; when in the rapid temperature increase and decrease mode, the user can exit the rapid temperature increase and decrease mode through voice or remote control. This significantly reduces the radiant heat transfer amount and improves the speed of temperature increase and decrease; because the loss of cold and heat is reduced, the actual power consumption of the air conditioner is reduced; the human body comfort is improved, and the influence of wall radiant heat transfer on the body sensation is reduced.
