Thus, the following detailed description of the embodiments of the present application, as provided in the accompanying drawings, is not intended to limit the scope of the application, as claimed, but is merely representative of selected embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present application without making any inventive effort, are intended to be within the scope of the present application.
It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further definition or explanation thereof is necessary in the following figures. Meanwhile, in the description of the present application, the terms "first", "second", and the like are used only to distinguish the description, and are not to be construed as indicating or implying relative importance.
Referring to fig. 1, fig. 1 is a control system of a fixed-frequency air conditioner in some embodiments of the present application, for controlling temperature adjustment of the fixed-frequency air conditioner, and externally installed on the fixed-frequency air conditioner, including:
the temperature module is used for acquiring indoor current temperature information;
the setting module is used for setting indoor regulated target temperature information;
the control module is used for reading the current temperature information and the target temperature information in real time, is provided with a temperature threshold value, and is also used for adjusting and reducing the air supply speed of the air conditioner when the difference value between the current temperature information and the target temperature information is smaller than the temperature threshold value.
According to the control system of the fixed-frequency air conditioner, the fixed-frequency air conditioner is externally arranged on the fixed-frequency air conditioner, the fixed-frequency air conditioner is generally used for an existing intelligent or non-intelligent fixed-frequency air conditioner, the control module can be used for reading current temperature information and target temperature information, and the air supply speed of the air conditioner is controlled according to the difference value between the two temperature information, so that the temperature change curve of the fixed-frequency air conditioner is stable, and the user feel more comfortable.
Specifically, when the difference between the current temperature information and the target temperature information is smaller than the temperature threshold, the control module adjusts and reduces the air supply speed of the air conditioner, namely reduces the air supply speed of the air conditioner.
More specifically, taking air-conditioning refrigeration as an example, since the refrigerating power of the compressor of the fixed-frequency air conditioner is constant, that is, the amount of cold generated in the evaporator in unit time of the air conditioner is measured, assuming that the refrigerating power of the compressor is sufficiently high (that is, the evaporator can still effectively exchange heat with the air supply at the highest wind speed), at this time, the refrigerating efficiency of the fixed-frequency air conditioner mainly depends on the air supply speed, the air-conditioning air supply cooling depends on the room cooling, the cooling generated by the heat exchange around the evaporator and the indoor temperature rising speed, and in the refrigerating process of the fixed-frequency air conditioner, the refrigerating is suspended when the current indoor temperature information reaches the target temperature information, and the refrigerating is started again at intervals or at a certain temperature rising degree; based on the fixed-frequency air conditioner operation logic, the control system of the fixed-frequency air conditioner sets a temperature threshold, when the difference value between the current temperature information and the target temperature information is smaller than the temperature threshold, the condition that the current temperature information is close to the target temperature information but the air conditioner stops refrigerating is indicated, at the moment, the control module adjusts the air conditioner to be low in air supply speed, namely, the integral air supply coldness is reduced, so that the refrigerating efficiency of the air conditioner to the indoor space is reduced, the indoor temperature change speed is reduced, under ideal conditions, when the refrigerating efficiency is equal to the indoor temperature rise, the current temperature information is slightly higher than the target temperature information, the indoor temperature is kept constant, the pseudo-frequency conversion function is achieved, the user feel is more comfortable, and the indoor temperature change process or the sudden stopping of the compressor cannot be annoyed.
In some preferred embodiments, the temperature module is an electronic thermometer that obtains indoor current temperature information that is an indoor temperature of a corresponding air conditioner installation site.
In some preferred embodiments, the setting module is a client, and may be one or more of a touch screen, a cloud webpage, an applet and an APP, so that the setting module is convenient for a user to operate and use, and is also beneficial to remote operation of the user.
Specifically, the target temperature information set by the setting module is set by the control module by sending an instruction to the air conditioner.
In some preferred embodiments, the temperature threshold is 0.5-1 ℃.
Specifically, the temperature threshold is set between 0.5 ℃ and 1 ℃, so that when the difference between the current temperature information and the target temperature information is between 0.5 ℃ and 1 ℃, the control module controls the air conditioner to adjust the air supply speed; the air conditioner is provided with the temperature sensor, the system in the application embodiment is externally arranged on the fixed-frequency air conditioner, and the temperature sensor of the air conditioner and the temperature at the sitting position of the temperature module possibly have certain deviation by combining the indoor local temperature difference, so that the temperature threshold value is set to be more than 0.5 ℃, the condition that the air conditioner stops refrigerating caused by the fact that the difference value of two temperature information detected by the system does not reach the temperature threshold value and the two temperature information detected by the air conditioner are the same can be avoided, and in addition, the air conditioner generally refrigerates to a temperature slightly lower than the target temperature information when refrigerating, and the problem that the air conditioner stops refrigerating in advance can be effectively avoided by setting the temperature threshold value of 0.5 ℃; in addition, the temperature threshold is set below 1 ℃, so that the problem that the current temperature information and the target temperature information are too large in gap when the air supply speed is regulated and reduced, and the temperature required by a user is far less than the target temperature information, so that discomfort is caused can be avoided.
In some preferred embodiments, the control module controls adjusting the air-conditioning air-supply speed to correspond to one of the three-speed air-supply speeds at which the air-conditioning speed is lowest when the difference between the current temperature information and the target temperature information is less than the temperature threshold.
Specifically, the air conditioner is utilized to carry out refrigeration efficiency adjustment by utilizing the lowest three-gear air supply speed of the air conditioner, and the proper low air supply speed can be dynamically selected for air supply based on the indoor temperature rise condition so as to stabilize the current temperature information, namely when the indoor temperature rise efficiency is higher, the low air supply speed with relatively higher air supply speed is selected for air supply, and when the indoor temperature rise efficiency is lower, the low air supply speed with relatively lower air supply speed is selected for air supply, so that the temperature dynamic adjustment is realized, and the indoor temperature can be ensured to be more stable.
More specifically, after the difference between the current temperature information and the target temperature information is smaller than the temperature threshold and the low air supply speed is adjusted to be started (the low air supply speed at the middle grade is preferred), the control module reads the current temperature information in real time, if the current temperature information is reduced for a certain time, such as 1 minute, the current temperature information indicates that the refrigerating efficiency is greater than the temperature rise efficiency, at this time, the low air supply speed with the relatively low air supply speed is adjusted to be used for air supply, if the current temperature information is increased for a certain time, such as 1 minute, the current temperature information is increased to indicate that the refrigerating efficiency is less than the temperature rise efficiency (the situation of opening doors and windows is more obvious), and at this time, the low air supply speed with the relatively high air supply speed is adjusted to be used for air supply.
In some preferred embodiments, when the air conditioner is delivering air at a low speed, the control module adjusts the speed of the air conditioner to increase if the difference between the current temperature information and the target temperature information increases beyond the temperature threshold.
In addition, there are situations that the lowest or highest low air supply speed still cannot keep the temperature stable, and these situations are mainly caused by that the indoor size is not matched with the air conditioner or the temperature is difficult to uniformly cover the whole area; when the refrigerating efficiency of the air conditioner with the lowest-grade low air supply speed is still greater than the indoor temperature rise speed, the current temperature information finally still reaches the target temperature information to stop refrigerating the air conditioner, but the temperature overall change curve is more stable compared with that of the common constant-frequency air conditioner when the air conditioner is directly used, so that a user is more comfortable; when the refrigerating efficiency of the air conditioner adopting the highest low-grade air supply speed is still smaller than the indoor temperature rising speed, after the difference value between the current temperature information and the target temperature information exceeds the temperature threshold value, the control module controls the air conditioner to switch to normal air supply speed for refrigerating, namely, the air supply speed is increased for air supply, so that the current temperature information is just stabilized at the temperature of the target temperature information increased by the temperature threshold value, and the temperature of a user body is continuously stabilized and comfortable.
In some preferred embodiments, during the period when the air conditioner stops cooling, the control module can also set temporary temperature information with a temperature value lower than the target temperature information, and the control module starts the air conditioner cooling again in advance according to the temporary temperature information and the temperature threshold value; assuming that the cooling is started again after the indoor temperature rises by 2 ℃ after the cooling of the air conditioner is stopped, the temperature threshold is set to be 1 ℃, a user feels gradually uncomfortable and even sweats in the temperature rising process, when the difference value between the current temperature information and the target temperature information is larger than the temperature threshold, namely, the indoor temperature rises to exceed 1 ℃ and still does not reach 2 ℃ so as to start the cooling of the air conditioner again, at the moment, the control module sets a temporary temperature information lower than the target temperature information in temperature as temporary target temperature information so as to start the cooling of the air conditioner, and when the current temperature information is reduced to the target temperature information, the control module cancels the temporary temperature information and sets the original target temperature information as the regulating temperature of the air conditioner, so that the temperature difference required by restarting the temperature rising of the air conditioner can be reduced, the indoor temperature change range is smaller and more comfortable.
As shown in fig. 2, in some preferred embodiments, the system further comprises:
the instruction module is used for acquiring instruction code information of the air conditioner;
the infrared module is used for sending out infrared signals for controlling the operation of the air conditioner;
the control module adjusts the air conditioner by calling instruction code information pairing and sending out corresponding infrared signals.
Specifically, according to the control system of the constant-frequency air conditioner, the instruction code information of the air conditioner to be controlled is obtained through the instruction module, so that the control module can call the corresponding instruction code information and convert the corresponding instruction code information into an electric signal which can be received by the combined infrared module, and the infrared module sends out an infrared signal corresponding to the instruction code information based on the electric signal of the control module, and effective operation control of the air conditioner is further achieved.
Specifically, the control system of the fixed-frequency air conditioner is externally arranged on the fixed-frequency air conditioner, namely, an independent control system independent of the existing fixed-frequency air conditioner is designed, and the control system is applicable to all fixed-frequency air conditioners on the market and has the characteristic of universality.
More specifically, the instruction module obtains the applicable instruction code information according to the air conditioner model, and obtains the instruction code information of the air conditioner of the corresponding model by accessing the internet or a database and the like.
In a second aspect, referring to fig. 3, fig. 3 is a method for adjusting a constant-frequency air conditioner according to some embodiments of the present application, for controlling a temperature adjustment of the constant-frequency air conditioner, the method includes the following steps:
acquiring and calculating the difference value between the indoor current temperature information and the target temperature information;
specifically, the current temperature information which can represent the indoor current temperature condition and the target temperature information which can represent the air conditioner working end point are respectively read, then the difference value of the two temperature information is calculated, and the difference value is combined with the set temperature threshold value to serve as the basis of air conditioner adjustment control.
And when the difference value between the current temperature information and the target temperature information is smaller than a temperature threshold value, sending out an adjusting signal to adjust and reduce the air supply speed of the air conditioner.
Specifically, reducing the air supply speed of the air conditioner can reduce the indoor refrigeration efficiency, so that when the current temperature information is close to the target temperature information (namely less than the temperature threshold), the indoor temperature change is smoother, and the human body feel is more comfortable.
Specifically, the temperature threshold is preset.
The adjusting method of the fixed-frequency air conditioner is generally used for the existing intelligent or non-intelligent fixed-frequency air conditioner, and controls the air supply speed of the air conditioner according to the difference value between the current temperature information and the target temperature information so as to enable the temperature change curve of the fixed-frequency air conditioner to be stable and enable the user to feel more comfortable; when the refrigerating efficiency is equal to the indoor temperature rise, namely, the cooling degree fed into the room at a low air supply speed is equal to the indoor temperature rise enthalpy value, the current temperature information is slightly higher than the target temperature information, so that the indoor temperature is kept constant, the function of pseudo-frequency conversion is achieved, the user feel more comfortable, and the user cannot feel annoyed and uncomfortable due to the indoor temperature change process or the sudden start and stop of the compressor.
In some preferred embodiments, the adjusting the reduced air conditioning supply speed is adjusted to correspond to one of the lowest speed three-speed supply speeds of the air conditioner.
Specifically, the air conditioner is utilized to carry out refrigeration efficiency adjustment by utilizing the lowest three-gear air supply speed of the air conditioner, and proper low air supply speed can be dynamically selected to stabilize the current temperature information based on the indoor temperature rise condition, namely when the indoor temperature rise efficiency is higher, the low air supply speed with relatively higher air supply speed is selected to carry out air supply, and when the indoor temperature rise efficiency is lower, the low air supply speed with relatively lower air supply speed is selected to carry out air supply, so that the temperature dynamic adjustment is realized, and the indoor temperature can be ensured to be more stable.
