Description

Time-control temperature-regulation method and device with adjustable frequency conversion coefficient of variable-frequency air conditioner and air conditioner
Technical Field
The invention relates to the technical field of air conditioners, in particular to a time-control and temperature-adjustment method and device with adjustable frequency conversion coefficients of a variable frequency air conditioner and the air conditioner.
Background
At present, air conditioners in the market are divided into a fixed-frequency air conditioner and a variable-frequency air conditioner. The fixed-frequency air conditioner operates at a fixed frequency, drives the compressor to operate at a fixed rotating speed, and continuously starts and stops the compressor to adjust the indoor temperature, but the fixed-frequency air conditioner is easy to cause unstable room temperature and brings inconvenience to users. In this context, inverter air conditioners are popular with users. In the prior art, the inverter air conditioner is provided with the inverter, the rotating speed of the compressor is changed by changing the output frequency of the inverter, and the purpose of controlling the room temperature is achieved by controlling the rotating speed of the compressor, so that the room temperature fluctuation is small, the electric energy consumption is low, and the comfort level is greatly improved. In the prior art, the frequency of the inverter air conditioner is adjusted in an automatic mode, the frequency of the inverter air conditioner is controlled to automatically adjust the output power supply frequency by comparing the ambient temperature with the temperature set by a user, so that the rotating speed of the compressor is correspondingly changed, the room temperature is always stabilized in a certain range, and the inverter air conditioner has a good effect of maintaining the room temperature when the room temperature reaches the temperature set by the user.
On the one hand, however, users often pay more attention to the temperature increasing and decreasing rate or the amount of power consumption in the temperature adjusting process, and the variable frequency air conditioner ignores the user demand when the room temperature does not reach the set temperature. For example, when a user urgently needs to increase or decrease the room temperature, the conventional variable frequency air conditioner can still automatically regulate and control the room temperature only according to the room temperature, and cannot rapidly increase the output frequency according to the user requirement to achieve the purpose of rapidly increasing and decreasing the temperature; or, when the user pays more attention to the effect of saving power, the existing variable frequency air conditioner still only can be automatically regulated and controlled according to the room temperature, and the air conditioner cannot be controlled to operate in a low-frequency range all the time so as to meet the energy-saving requirement of the user. On the other hand, the variable frequency air conditioner can not enable a user to intuitively feel the temperature adjustment speed, and the influence of the operation time on the temperature adjustment is not considered, so that the user requirements cannot be combined, the temperature adjustment sufficiency is guaranteed, and certain inconvenience is brought to the user.
In summary, the conventional inverter air conditioner can effectively maintain the temperature, but when the room temperature does not reach the range of the user requirement, i.e. in the process of temperature increase and decrease, the output frequency is automatically adjusted and controlled only according to the room temperature, and it is not determined whether the user tends to increase and decrease the temperature quickly or operate in a power-saving manner in the process of temperature adjustment, so that the output frequency of the inverter cannot be adjusted according to the user requirement to achieve the effect of the user requirement. Meanwhile, the conventional variable frequency air conditioner cannot enable a user to intuitively know the temperature regulation speed, and cannot control the air conditioner more reasonably by combining the self demand, so that the sufficiency of the temperature regulation effect is not considered by combining the running time of a frequency converter, and the temperature regulation effect of the air conditioner cannot completely meet the demand of the user.

In addition, an index for intuitively measuring the temperature regulation speed is provided, namely the temperature regulation rate is intuitively measured by calculating the predicted running time, if the predicted running time is longer, the setting of the user can result in the slower temperature regulation rate, and otherwise, if the predicted running time is shorter, the setting of the user can result in the faster temperature regulation rate. In conclusion, the invention meets the requirements of users on different aspects of temperature rising and reducing rate and power saving efficiency, and simultaneously intuitively measures the temperature adjusting speed through the estimated operation time, thereby facilitating the setting of the users, measuring whether the temperature is sufficiently adjusted or not by combining the operation time and the environment temperature, increasing the degree of independence of the users on selecting the operation mode of the air conditioner, and improving the comfort level of the users.

Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
In the prior art, the frequency conversion air conditioner continuously adjusts the output frequency to maintain the room temperature within the range required by the user when the room temperature reaches the temperature set by the user. However, when the room temperature does not reach the temperature set by the user, that is, during the temperature adjustment process, the user often does not need to maintain the temperature, but rather pays more attention to the rapid temperature adjustment to reach the required temperature, or operates with the least power consumption to reach the required temperature. In the process of temperature rising and falling of the existing variable frequency air conditioner, the output frequency is regulated and controlled only according to the room temperature, and whether the user tends to rise and fall the temperature quickly or run in a power-saving mode in the temperature regulating process is not judged, so that the output frequency of the frequency converter cannot be regulated according to the user requirement, the compressor runs according to the frequency required by the user, the effect of quick temperature regulation or high-efficiency power saving of the user requirement is achieved, meanwhile, the temperature regulating duration is not measured according to specific indexes, and whether sufficient temperature regulation is carried out or not cannot be judged fully according to the running duration.

In step S2, the estimated operation time for the ambient temperature to reach the set temperature is determined based on the set temperature and the set output frequency. The estimated running time is determined so that the running time is compared with the estimated running time to determine whether the temperature is sufficiently adjusted.
In step S3, the frequency converter is controlled to operate at the set output frequency according to the first external command signal, and the actual operation time of the frequency converter operating at the set output frequency is obtained. Therefore, under the condition that the room temperature does not reach the set temperature, the frequency converter is controlled to operate at the set output frequency required by the user according to the requirement of the user by combining the advantage of fixed frequency, so that the compressor is controlled to operate at the frequency required by the user: when a user sets a higher set output frequency, the frequency converter outputs a higher frequency to drive the compressor to run at a higher frequency, so that the aim of quickly increasing and decreasing the temperature can be fulfilled; when the user sets a lower set output frequency, the frequency converter outputs the lower frequency to drive the compressor to run at the lower frequency, so that the purpose of power-saving running can be achieved, and the actual running time is obtained so as to be used as a condition for judging the locked set output frequency. The output frequency is set by the user, the requirements of the user on energy saving and power saving or quick temperature adjustment are met according to the selection of the user, the degree of independence of the user on selection of the air conditioner operation mode is increased, and the comfort level of the user is improved.
In step S4, it is determined whether the actual operating time and the ambient temperature reach preset conditions based on the estimated operating time and the set temperature. Therefore, whether the set output frequency is continuously locked or not is judged according to the actual operation time and the environment temperature, whether the temperature is sufficiently adjusted or not is measured by combining the actual operation time and the environment temperature, the influence of the actual operation time and the environment temperature on the temperature adjusting effect is fully considered, the temperature adjustment control is carried out more reasonably, and the use of a user is facilitated.
If so, the frequency converter is controlled not to be locked at the set output frequency any more, and the automatic frequency conversion mode is operated in step S5. Through combining the advantage of frequency conversion and deciding frequently, when not fully adjusting the temperature, utilize the output of the settlement output frequency control converter of user's setting to this satisfies the user to the demand of cooling and heating rate or power saving efficiency, and when fully adjusting the temperature, then utilize the frequency conversion to maintain the temperature in the demand within range all the time. When the temperature is increased and decreased, the fixed frequency locking is utilized to set the output evaluation rate, the overweight requirements of a user on the temperature increasing and decreasing speed rate and the power saving efficiency are met, when the set temperature is reached, the temperature is maintained by utilizing the frequency conversion, the advantages of frequency conversion and fixed frequency combination are fully utilized, and the different requirements of the user on the temperature increasing and decreasing and the temperature maintaining are met.

Fig. 2 is a flowchart illustrating the process of determining whether the actual operation time and the ambient temperature reach the preset conditions according to the embodiment of the present invention, which includes steps S41 to S42.
In step S41, if the actual operating time reaches the estimated operating time, it is determined whether the ambient temperature reaches the set temperature. Firstly, whether the actual running time reaches the expected running time is determined, so that the temperature adjustment is carried out for a sufficient time, and then the temperature adjustment is further regulated and controlled by judging the room temperature, so that the sufficiency of the temperature adjustment is ensured.
In step S42, if the ambient temperature reaches the set temperature, it is determined that the actual operation time and the ambient temperature reach the preset conditions. Whether sufficient temperature adjustment is performed or not is determined by combining the operation time and the environment temperature, the temperature adjustment requirement of a user is fully met, and the use comfort of the user is improved.
Optionally, after determining the expected operation time when the ambient temperature reaches the set temperature according to the set temperature and the set output frequency, the method further includes: the predicted runtime is sent to the user device, where it is displayed. Therefore, the expected operation time is displayed on the user equipment through control, so that an intuitive index for measuring the temperature regulation speed is provided, a user can more directly know whether the selected set output frequency can meet the requirement of the user on the temperature regulation rate, the user can more conveniently and independently set the temperature, for example, when the requirement is low-frequency operation until the set temperature is 26 ℃, and when the user sets 30HZ or 35HZ, the user cannot intuitively sense the speed difference of the 30HZ or 35HZ, but by determining the operation time under the 30HZ and the operation time under the 35HZ, the user can more easily set the corresponding set output frequency according to the required operation time, the user requirement can be more accurately and efficiently met, and the user setting is convenient. In addition, displaying the estimated running time facilitates the user to plan time reasonably, such as when the user goes out to buy things after setting the temperature, and if he knows when the set temperature is reached, the user can schedule his time reasonably and get a comfortable temperature environment home.
In one embodiment of the present invention, the transmitting the predicted runtime to the user equipment, and after displaying the predicted runtime on the user equipment, further comprises: the user judges whether the current setting needs to be adjusted or not according to the displayed estimated running time; if the adjustment is needed, the first external instruction signal is continuously sent to adjust and set the output frequency, or the second external instruction signal is continuously sent to adjust and set the temperature until the user is satisfied with the displayed expected running time and sends a confirmation instruction through the user equipment.

When the displayed estimated running time is less than the time expected by the user, the temperature adjusting speed is fast, the power consumption is high, the user can adjust the set output frequency to be small according to the requirement of the user, and the temperature is adjusted to be high when the user cools and is adjusted to be low when the user heats; when the displayed estimated running time is longer than the time expected by the user, the temperature adjusting speed is very slow, the power consumption is low, the user can adjust the set output frequency to be high according to the requirement of the user, and the temperature is adjusted to be low during refrigeration and high during heating. Therefore, the invention provides an index for intuitively measuring the temperature regulation speed by calculating the predicted running time, and is convenient for users to further regulate and control selection.

Optionally, before acquiring the first external instruction signal and the second external instruction signal and simultaneously acquiring the ambient temperature, the MCU performs key detection to determine whether the setting mode is a cooling or heating mode, and if so, acquires the first external instruction signal and the second external instruction signal. Because the temperature is required to be adjusted only when the user sets refrigeration or heating, and in other modes, such as a dehumidification mode or a drying mode, the user does not need to adjust the temperature, and the requirements of quick temperature adjustment or power saving temperature adjustment are not met, the key detection is carried out, the mode without temperature adjustment is eliminated, the operation of a redundant control method with controllable frequency coefficients is avoided, and the energy and the power are saved.
