Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
Fig. 1 is a schematic flow chart of a control method of an air conditioner according to an embodiment of the present invention. The control method of the air conditioner provided by the first embodiment of the present invention is executed through steps S11 to S14:
s11, detecting the outdoor temperature in real time;
s12, when the outdoor temperature is larger than or equal to a preset temperature threshold value, controlling a fresh air fan to be started;
specifically, a temperature threshold is preset, and the condition that the outdoor temperature reaches the preset temperature threshold is used as the starting condition of the fresh air fan. After the air conditioner is started, detecting the temperature value of the outdoor environment in real time, comparing the outdoor temperature detected in real time with the preset temperature threshold value, and controlling the new fan to start to perform corresponding work when the outdoor temperature is judged to be greater than or equal to the preset temperature threshold value. It can be understood that when the outdoor temperature detected in real time is less than the preset temperature threshold, the new fan is forced not to be started, that is, the new fan does not work.
Furthermore, a fixed time interval can be set to detect the primary outdoor temperature, and the primary outdoor temperature is compared with a preset temperature threshold value to control the opening and closing states of the fresh air fan, so that the control on the opening or closing of the fresh air fan is effectively realized, and the power consumption loss and the like caused by continuous work of a device for detecting the outdoor temperature can also be avoided. Preferably, the outdoor temperature is set to be detected once an hour.
S13, detecting indoor environment parameters and indoor personnel parameters in real time after the new fan is started;
and S14, controlling the fresh air machine to operate in a corresponding operation mode according to the indoor environment parameters and the indoor personnel parameters.
Specifically, the indoor environmental parameters include PM2.5 concentration and carbon dioxide concentration; the indoor personnel parameter comprises the number of indoor personnel. After the new fan is started, the concentration of PM2.5 and the concentration of carbon dioxide in the indoor environment and the number of indoor personnel are detected in real time. According to the detected PM2.5 concentration and carbon dioxide concentration in the indoor environment and the number of indoor personnel, a corresponding control strategy suitable for the working of the fresh air machine is generated, the fresh air machine is controlled to operate in a corresponding operation mode, and the comfort level of a user in the indoor air-conditioning environment is effectively improved.
Further, a first standard concentration and a first excess concentration, which are smaller than the first excess concentration, are set in advance as two concentration threshold parameters relating to the PM2.5 concentration. When the indoor PM2.5 concentration is less than the first standard concentration, the particulate matter pollution of the indoor environment is less, and the air quality is better; when the concentration of the indoor PM2.5 is greater than the first standard exceeding concentration, the air quality of the indoor environment is poor, and pollution is serious. A second standard concentration and a second exceeding concentration are preset as two concentration threshold parameters related to the concentration of carbon dioxide, wherein the second standard concentration is smaller than the second exceeding concentration. When the indoor carbon dioxide concentration is lower than the second standard concentration, the carbon dioxide concentration of the indoor environment is lower, and the air quality is better; and when the indoor carbon dioxide concentration is higher than the second overproof concentration, the carbon dioxide concentration in the indoor environment is overproof, and the air quality is poor.
Specifically, step S14 is specifically executed by the following steps S141 to S146:
and S141, when the concentration of PM2.5 is greater than a first standard exceeding concentration or the concentration of carbon dioxide is greater than a second standard exceeding concentration and the number of indoor personnel is equal to 0, controlling the fresh air fan to operate in a fresh air mode and low-grade wind.
And S142, when the concentration of the PM2.5 is greater than a first standard exceeding concentration or the concentration of the carbon dioxide is greater than a second standard exceeding concentration and the number of indoor personnel is greater than 0, controlling the fresh air fan to operate in a fresh air mode at a high-speed wind.
It can be understood that when the concentration of PM2.5 is greater than the first standard exceeding concentration, or the concentration of carbon dioxide is greater than the second standard exceeding concentration, both the concentration of PM2.5 and the concentration of carbon dioxide in the indoor environment exceed the standards, and at this time, the indoor air quality is poor, the air pollution is serious, and a new fan needs to be started to purify the air. If the number of indoor personnel is 0 at this moment, only need control new fan with the operation of new trend mode low-grade wind, can realize indoor air purification, also can reduce the operation consumption of new fan simultaneously, prolong new fan's life. If the number of indoor personnel is greater than 0, the indoor air purification efficiency needs to be enhanced in consideration of the activities of the indoor personnel, the fresh air machine needs to be controlled to operate in a fresh air mode at a high-grade wind, and the comfort level of the indoor personnel in the air conditioning environment is improved.
It should be noted that, in the fresh air mode, both the fresh air motor and the exhaust motor operate. Fresh air outside the room is introduced into the room through the fresh air motor, and polluted air inside the room is discharged through the exhaust motor.
S143, when the concentration of the PM2.5 is smaller than a first standard concentration, the concentration of the carbon dioxide is smaller than a second standard concentration, and the number of the indoor personnel is equal to 0, controlling the fresh air fan to stop running.
S144, when the concentration of the PM2.5 is smaller than a first standard concentration, the concentration of the carbon dioxide is smaller than a second standard concentration, and the number of indoor people is larger than 0, controlling the fresh air fan to operate in a fresh air mode and low-grade wind.
It is understood that when the PM2.5 concentration is less than the first standard concentration and the carbon dioxide concentration is less than the second standard concentration, the PM2.5 concentration and the carbon dioxide concentration of the indoor environment are small, and both are in a standard state, and the indoor air quality is high. If the number of indoor personnel equals 0 at this moment, then need not start the new fan and carry out air purification, control new fan stop operation to reduce new fan's operation consumption, prolong new fan's life. If the indoor personnel quantity is greater than 0 at this moment, consider that indoor personnel's activity needs carry out air purification and circulation, then need control new fan with the low-grade wind operation of new trend mode, effectively improve the comfort level of indoor personnel under the air conditioning environment, also can reduce the operation consumption of new fan simultaneously, prolong new fan's life.
S145, when the concentration of the PM2.5 is greater than or equal to a first standard concentration and less than or equal to a first superscalar concentration, the concentration of the carbon dioxide is less than a second standard concentration, and the number of the indoor personnel is greater than 0, controlling the fresh air fan to operate in a wind shielding mode in a purification mode.
It is understood that when the concentration of PM2.5 is after the first standard concentration and the first excessive concentration, and the concentration of carbon dioxide is less than the second standard concentration, it indicates that the concentration of PM2.5 in the chamber is slightly higher, and the concentration of carbon dioxide is smaller, and particulate pollution exists in the chamber. If the number of indoor personnel is greater than 0, the indoor personnel activity is considered, air purification needs to be carried out, the fresh air fan is controlled to operate in a wind shielding mode, air purification is effectively achieved, and the comfort level of the indoor personnel in the air conditioning environment is improved. It should be noted that, in the purification mode, the fresh air motor operates, and the exhaust motor is turned off.
Further, the indoor personnel parameters also comprise indoor personnel types; and the indoor person types include the elderly, children, pregnant women, and adults; therefore, after the new fan is started, the method also comprises the step of detecting the type of indoor personnel in real time.
S146, when the concentration of PM2.5 is smaller than or equal to a first exceeding standard concentration, the concentration of carbon dioxide is larger than or equal to a second standard concentration and smaller than or equal to a second exceeding standard concentration, and the number of indoor personnel is larger than 0, controlling the fresh air fan to operate in a fresh air mode with the air speed as r;
wherein R is mxr/C; m ═ X × X1+y×X2+m×X3+n×X4；
R is the wind speed of the new fan, R is the maximum rotating speed of the new fan, and C is the maximum fresh air volume of the new fan; x1、X2、X3、X4Respectively the fresh air volume required by the old, children, pregnant women and adults every hour, and x, y, m and n are the number of the old, children, pregnant women and adults indoors respectively.
It can be understood that when the concentration of PM2.5 is less than or equal to the first superstandard concentration, and the concentration of carbon dioxide is between the second standard concentration and the second superstandard concentration, the indoor environment quality is medium, the air quality needs to be further improved, and if the number of indoor personnel is greater than 0 at the moment, the wind speed of the fresh air fan is determined according to the type of indoor personnel, the number of each type of personnel, and the fresh air volume required by each person of each type of personnel per hour, and the operation mode and the wind speed of the fresh air fan are controlled. The comfort level of indoor personnel in the air-conditioning environment is effectively improved, the operation power consumption of the air conditioner can be effectively reduced, and the reduction of the service life of the air conditioner due to continuous operation is avoided.
It should be noted that there is no sequence in the execution timings of steps S141 to S146, and according to the detection of the indoor environmental parameters and the indoor personnel parameters, a corresponding control strategy is selected to control the fresh air machine to operate in a corresponding operation mode.
The embodiment of the invention provides a control method of an air conditioner, which controls the opening of a fresh air machine by detecting the outdoor temperature in real time; and after the fresh air machine is started, detecting indoor environmental parameters and indoor personnel parameters in real time so as to control the fresh air machine to operate in a fresh air mode or a purification mode and control the fresh air machine to operate at different wind speeds.
