Temperature rise and fall control method based on intelligent interconnectionTechnical Field
The invention belongs to the technical field of air conditioners, and particularly relates to an intelligent interconnection-based temperature rise and fall control method.
Background
With the use of various intelligent interconnected home devices, intelligent interconnected home devices such as intelligent air conditioners, televisions, windows, curtains, lamps and the like are moved into thousands of households. A user can control various smart home devices through voice, motion, portable terminals, etc. Meanwhile, various household devices are mutually related and controlled.
In three aspects:
although the smart interconnected home can be controlled by voice, motion, portable terminals and the like, the smart interconnected home still needs participation of people, and a user is required to send out instructions, so that the intelligence is required to be further improved. The ideal result is that the home equipment can automatically give the optimal scheme through acquiring information of environment, clients and the like, and automatically start and execute the scheme. Thus, the user operation is not needed, and the optimal effect is achieved.
At present, the air conditioner is used for controlling the rapid cooling and heating of the air conditioner (and a user is often required to set a super-strong cooling or super-forced heating mode through a remote controller) so as to achieve the purpose of rapid temperature rise and fall of a room. Therefore, the effect of temperature rise and reduction is limited, and the speed is low. The direct heat exchange and radiation heat exchange values between the window and the wall and the outside are very large, if the loss can be reduced, the indoor temperature rise and drop speed can be greatly improved, and the actual power consumption of the air conditioner can be greatly reduced.
The heat lost by radiant heat exchange is enormous.
The human body exchanges heat with the surrounding environment in three modes of convection, radiation and evaporation, and the heat conduction is negligible.
The temperature of the air determines the temperature difference between the surface of the human body and the convection heat exchange of the environment, so that the convection heat exchange quantity is influenced, but the indoor wind speed is low, and the convection heat exchange quantity accounts for 30% of the heat dissipation quantity of the human body;
Radiation heat exchange, namely, the radiation heat exchange occupies 50 percent of the heat dissipation capacity of the human body. The radiation heat exchange (radiation HEAT TRANSFER) refers to a heat exchange process between two objects with different temperatures and without contact with each other through electromagnetic waves, and each object in nature continuously emits radiation heat to a space and simultaneously continuously absorbs radiation heat emitted by other objects. The radiation heat exchange between two objects is related to the blackness of the objects and the temperature difference of the surfaces of the objects. The larger the temperature difference between the two objects, the larger the radiation heat exchange.
Heat is exchanged between the human body and the environment mainly by convection and radiation, and the heat conduction is basically negligible (the heat conduction coefficient of air is very low). Under the ordinary indoor climate condition, the human body surface temperature is higher than the environment average radiation temperature, and the indoor wind speed is generally smaller, so the radiation heat dissipation capacity can account for about 50% of the total heat dissipation capacity, the convection heat dissipation capacity is about 30%, and the rest is the evaporation heat dissipation capacity.
Therefore, the heat radiation has great influence on the heat dissipation of the human body. Not only for human bodies, but also the influence of heat radiation on indoor objects and indoor temperature is particularly great. As long as the temperature of the surface of the human body is inconsistent with the temperature of the surrounding surface, radiation heat exchange can be carried out between the human body and the environment. This is why the indoor temperature is also 20 ℃ and the somatosensory feel is completely different in summer and winter. In summer, the temperature of the wall body and the window is high, the temperature of the human body is low, and the human body receives a large amount of heat radiation from the wall body window to feel heat. Similarly, indoor objects can receive heat radiation from wall windows, and more cooling energy is required to maintain the same indoor temperature. In winter, the temperature of the wall body and the window is very low, the temperature of the human body is high, and the human body can absorb a large amount of heat by the wall body window through heat radiation and feel cold. Maintaining the same indoor temperature requires more heat. If the radiation heat exchange of human body, indoor object and wall window can be reduced, the comfort level of human body and indoor temperature rise and reduction speed can be greatly improved, and the power consumption of the air conditioner can be reduced.
