Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, 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 some, but not all, embodiments of the present invention. The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.
Furthermore, the appearances of the terms "first," "second," and the like, if any, are used solely to distinguish one from another and are not to be construed as indicating or implying relative importance.
It should be noted that the features of the embodiments of the present invention may be combined with each other without conflict.
At present, the air conditioner is generally tested and developed according to the connecting pipe with the standard pipe length in the industry, but most users use the connecting pipe with the pipe length larger than the standard pipe length. In such a case, after the air conditioner is operated, the pressure loss of the indoor unit and the outdoor unit connecting air pipe is increased, and the evaporation temperature is increased, thereby causing insufficient heating capacity of the air conditioner. The frequency regulation and control mode of the existing unit machine mainly can reach the optimal operation state when a connecting pipe with a standard pipe length is used, and can ensure both the heating capacity and the operation reliability. However, this adjustment ignores the pressure loss of the connection pipe and often also performs frequency limitation, so that the comfort of the user using the air conditioner is poor.
Based on the above situation, the frequency regulation and control method provided by the embodiment of the present specification can effectively alleviate the problem that the experience of the user using the air conditioner is poor due to the influence of the length of the connecting pipe.
As shown in fig. 1, an embodiment of the present invention provides a frequency regulation method, where the air conditioner further includes an internal unit, an external unit, and a connection pipe, the external unit is connected to the internal unit through the connection pipe, and the regulator is respectively in communication connection with the internal unit, the external unit, and the connection pipe, and the method includes the following steps as shown in fig. 2:
step S01: and acquiring the tube length of the connecting tube.
Step S02: and determining a target frequency regulation and control mode according to the pipe length specification of the pipe length of the connecting pipe.
Step S03: and regulating and controlling the frequency of the air conditioner based on the target frequency regulation and control mode to obtain the regulated and controlled frequency.
Step S04: and controlling the air conditioner to operate according to the regulated and controlled frequency.
The controller may be a device with control and data processing functions disposed on the indoor unit or the outdoor unit, or may be a separate device independent of the air conditioner, such as various intelligent terminals like a mobile phone and a tablet, or a device matched with the air conditioner. When the unit machine is in heating operation, the frequency of the compressor of the air conditioner and the connecting pipe have no corresponding control relation, and when the connecting pipe is lengthened, the pressure loss of the connecting pipes of the inner machine and the outer machine is increased.
In step S01, the length of the connecting tube may be obtained in various ways, for example: the pipe length of the connecting pipe is measured in a sonar mode to obtain the pipe length of the connecting pipe. For another example, the tube length of the connection tube is measured by an infrared detection device, and the tube length of the connection tube is obtained. It is also possible to provide a sensor at each end of the connecting tube, and in the test phase, the length of the connecting tube is obtained based on the flow rate of the liquid flowing in from one end of the connecting tube and the time taken to flow out from the other end of the connecting tube, and so on.
Optionally, the obtaining the tube length of the connecting tube includes:
and acquiring the air outlet temperature of the internal machine. And acquiring the pipe length of the connecting pipe according to the air outlet temperature.
When the air conditioner is developed, the air conditioner is tested at a free frequency, other frequency limits are shielded, and the relation between the air outlet temperature of the compressor and the connecting pipe can be tested. Because the air outlet temperature difference is small when liquid is added and is difficult to distinguish, liquid is not added when the relation between the air outlet temperature and the connecting pipe is tested. The air-out temperature is inversely proportional to the length of the connecting pipe, when the air-out temperature is tested, the air-out temperature is always changed along with the length of the connecting pipe, the connecting pipe is lengthened, the pressure loss is increased, the pressure loss accumulation is carried out, the control is carried out according to the specification, the control complexity can be reduced, and the control is more stable and reliable.
Through testing, the air outlet temperature of a general compressor is inversely proportional to the length of the connecting pipe, and the air outlet temperature is obviously reduced in different ranges of the length of the connecting pipe.
As shown in fig. 3, the relationship between the outlet air temperature and the length of the connecting pipe is shown when the length of the connecting pipe is 25m, the length of the standard connecting pipe is 5m, and the length of the connecting pipe is 5 sections. T1 is the temperature of lubricating oil in a compressor cavity of a compressor when a standard pipe length connecting pipe is in a free frequency, T2 is the temperature of the lubricating oil in the compressor cavity when the connecting pipe length is 25m, a, b, c and d respectively represent different pipe lengths of the connecting pipe, and Ta, tb, tc and Td respectively represent air outlet temperatures corresponding to a, b, c and d. In practical situations, the lengths of the pipes a, b, c, and d and the lengths of the pipes Ta, tb, tc, and Td corresponding to the lengths are different, and the measurement can be performed according to practical situations.
Based on the test data, the pipe length of the connecting pipe can be obtained through the air outlet temperature of the compressor under the condition that the unit configuration is determined. For example, in the R32 refrigerant of the inverter 72, when T2 is 36.6 ℃, the pipe length of the connecting pipe can be 25m.
And after the pipe length of the connecting pipe is obtained, executing the step S02, and determining a target frequency regulation and control mode according to the pipe length specification of the pipe length of the connecting pipe.
For connecting pipes with different pipe lengths, different frequency regulation modes are adopted as target frequency regulation modes, and the frequency of the air conditioner can be regulated and controlled more accurately.
Optionally, the pipe length specifications include a first specification, a second specification, a third specification and a fourth specification, the first specification is a range from a first pipe length to a second pipe length, and the first pipe length is greater than or equal to a standard pipe length of the connecting pipe; the second specification is a range between the second tube length and a third tube length, and the second tube length is greater than or equal to the first tube length; the third specification is a range between the third tube length and a fourth tube length, and the third tube length is greater than or equal to the second tube length; the fourth specification is a range between a fourth tube length and a fifth tube length, the fourth tube length being greater than or equal to the third tube length; the determining a frequency regulation and control mode according to the pipe length specification of the pipe length of the connecting pipe comprises the following steps:
and if the connecting pipe is in the first specification, determining that a first frequency regulation and control mode is the target regulation and control mode.
And if the connecting pipe is in the second specification, determining that a second frequency regulation mode is the target regulation mode.
And if the connecting pipe is in the third specification, determining that a third frequency regulation and control mode is the target regulation and control mode.
And if the connecting pipe is in the fourth specification, determining that a fourth frequency regulation mode is the target regulation mode.
The pipe length specification may be a specification of the pipe length of the connecting pipe according to actual conditions, and each section represents a different range of the pipe length of the connecting pipe, for example, the longest pipe length of the connecting pipe is preset to be 30m, and is divided into 3 sections, 0-8 m is a first pipe length specification, 9-16 m is a second pipe length specification, and 17-30 m is a third pipe length specification. After the length of the connecting pipe is obtained, different frequency regulation and control modes are determined to control the frequency of the air conditioner according to the pipe length specification where the length of the connecting pipe is located, and therefore the regulated and controlled frequency of the air conditioner is determined.
For better illustration of the present invention, as an alternative embodiment, as shown in fig. 4, the tube length specification may be set as a first specification a, a second specification B, a third specification C and a fourth specification D, wherein the first specification a may be in a range from a first tube length a to a second tube length B, and the first tube length a is greater than or equal to a standard tube length of a connecting tube (i.e. a tube length of a conventional connecting tube on the market); the second specification B is a range from a second tube length B to a third tube length c, and the second tube length B is greater than or equal to the first tube length a; the third specification C is a range between a third tube length C and a fourth tube length d, the third tube length C being greater than or equal to the second tube length b; the fourth specification D is a range between a fourth tube length D and a fifth tube length e, and the fourth tube length D is equal to or greater than the third tube length c. In the following, the solution of the invention will be illustrated with the above examples.
The first frequency regulation mode, the second frequency regulation mode, the third frequency regulation mode and the fourth frequency regulation mode are different frequency regulation modes, and the frequencies of the air conditioner are regulated and controlled by adopting different frequency regulation modes under different connecting pipe lengths.
And S03, regulating and controlling the frequency of the air conditioner based on the target frequency regulation and control mode to obtain the regulated and controlled frequency.
Optionally, the outdoor unit includes a compressor, and the controlling the frequency of the air conditioner based on the target frequency controlling mode includes:
if the target frequency regulation mode is the first frequency regulation mode.
The upper frequency limit of the air conditioner is adjusted to a first upper frequency limit and the upper discharge temperature limit of the compressor is adjusted to a first discharge temperature.
And acquiring the frequency of the air conditioner after the first time period.
And determining the frequency of the air conditioner after the first time period as the regulated frequency.
If the pipe length of the connection pipe is in the first specification a, it means that the pipe length of the connection pipe has affected the adjusting capability of the air conditioner, but the discharge pressure of the compressor is still in the normal range that can maintain the frequency of the air conditioner. It is thus possible to determine the target frequency regulation mode as the first frequency regulation mode. The first frequency regulation mode may be the following steps:
the upper limit of the frequency of the air conditioner is adjusted to a first upper limit frequency, and the upper limit of the exhaust temperature of the compressor is adjusted to a first exhaust temperature. After the previous exhaust temperature and the upper limit of the air conditioning frequency are cancelled, the air conditioning frequency is increased. After the first time period, when the frequency of the air conditioner is stable, the frequency of the air conditioner at the time is acquired, and the frequency is used as the regulated and controlled frequency of the air conditioner.
For example, if the upper limit of the initial heating frequency of the air conditioner is 90hz, a =8.5m, b =12.5m, the first exhaust temperature is 103 ℃, the first time duration is 30s, and the first upper limit frequency is 95Hz. If the length of the connecting pipe is 10m, the original upper limit of the frequency of the air conditioner is increased to 95Hz, and then after 30s, the frequency of the air conditioner at the moment is taken as the regulated frequency.
Optionally, the controlling the frequency of the air conditioner based on the target frequency controlling mode further includes:
if the target frequency regulation mode is the second frequency regulation mode.
Adjusting the upper frequency limit of the air conditioner to a second upper frequency limit, and adjusting the upper exhaust temperature limit to a second exhaust temperature, wherein the second upper frequency limit is greater than the first upper frequency limit, and the second exhaust temperature is greater than the first exhaust temperature.
And acquiring the frequency of the air conditioner after the second time period.
And determining the frequency of the air conditioner after the second time period as the regulated frequency.
The second upper limit frequency may be an upper limit of an air conditioning frequency preset by a developer, and the second upper limit frequency is greater than the first upper limit frequency; the second time duration may be a time duration set by the developer, the second time length can be different from the first time length and can also be the same as the first time length; the second exhaust temperature may be a temperature value preset by a developer, and the second exhaust temperature is greater than the first exhaust temperature.
If the obtained length of the connecting pipe is in the second specification B, determining that the target frequency regulation mode is the second frequency regulation mode, where the mode may include the following steps:
and adjusting the upper limit of the frequency of the air conditioner to a second upper limit frequency, and adjusting the upper limit of the exhaust temperature of the compressor to a second exhaust temperature. After the previous exhaust temperature and the upper limit of the air conditioning frequency are cancelled, the air conditioning frequency is increased. After the second time period, when the frequency of the air conditioner is stable, the frequency of the air conditioner at the time is acquired, and the frequency is used as the regulated and controlled frequency of the air conditioner.
For example, if the upper limit of the initial heating frequency of the air conditioner is 90hz, b =12m, c =15.5m, the second exhaust temperature is 106 ℃, the second time period is 30s, and the second upper limit frequency is 96Hz. If the length of the connecting pipe is 13m, the original upper limit of the frequency of the air conditioner is increased to 96Hz, and then after 30s, the frequency of the air conditioner at the moment is taken as the regulated frequency.
Optionally, the controlling the frequency of the air conditioner based on the target frequency controlling mode further includes:
and if the target frequency regulation mode is the third frequency regulation mode.
Adjusting the upper frequency limit of the air conditioner to a third upper frequency limit, and increasing the frequency of the air conditioner according to the first speed, wherein the third upper frequency limit is greater than the second upper frequency limit.
A discharge pressure of the compressor is monitored.
And when the exhaust pressure is greater than the first exhaust pressure, stopping raising the frequency of the air conditioner.
And when the exhaust pressure is determined to be greater than the first exhaust pressure, the frequency of the air conditioner is the regulated and controlled frequency.
The third upper limit frequency, the first speed and the first exhaust pressure can be values preset by developers, and the third upper limit frequency is greater than the second upper limit frequency; the first speed may be a speed deemed to set an up air conditioning frequency, such as 1Hz every 16 seconds.
If the obtained length of the connecting pipe is within the third specification C, determining that the target frequency regulation mode is a third frequency regulation mode, wherein the frequency regulation mode of the mode comprises the following steps:
the upper frequency limit of the air conditioner is set to a third upper limit frequency, and then the frequency of the air conditioner is increased at a first speed. While boosting the air conditioner, monitoring whether a discharge pressure of the compressor is greater than a first discharge pressure. And when the exhaust pressure of the compressor is detected to be greater than the first exhaust pressure, stopping raising the frequency of the air conditioner, and taking the frequency of the air conditioner at the moment as the regulated frequency.
For example, the current frequency of the air conditioner is 95Hz, the third upper limit frequency is 100Hz, the first speed is 1Hz adjusted up every 15s, and the first exhaust pressure is 3.2MPa. If the obtained length of the connecting pipe is in the third specification C, the upper limit of the frequency of the air conditioner is set to be 100Hz, and then the frequency of the air conditioner is increased at the speed of increasing 1Hz every 15 s. And monitoring whether the exhaust pressure of the compressor is more than 3.2MPa or not while the air conditioner is subjected to frequency boosting. And if the discharge pressure of the compressor is detected to be more than 3.2MPa after 30s, taking 97Hz as the regulated frequency.

The exhaust pressure is monitored.
And when the exhaust pressure is greater than the second exhaust pressure or the exhaust temperature reaches the third exhaust temperature, stopping raising the frequency of the air conditioner.
And when the exhaust pressure is determined to be greater than the second exhaust pressure or the exhaust temperature reaches the third exhaust temperature, the frequency of the air conditioner is the regulated and controlled frequency.
The fourth upper limit frequency, the second speed, the third exhaust temperature and the second exhaust pressure can be values preset by developers, and the fourth upper limit frequency is greater than the third upper limit frequency; the second speed may be the same as or different from the first speed.
If the obtained length of the connecting pipe is within a fourth specification D, determining that the target frequency regulation mode is a third frequency regulation mode, wherein the third frequency regulation mode comprises the following steps:
the upper limit of the frequency of the air conditioner is set to be the fourth upper limit frequency, and the upper limit of the exhaust temperature is adjusted to be the third exhaust temperature. And then up-converts the air conditioner according to the second speed. Meanwhile, it is monitored whether the exhaust pressure is greater than the second exhaust pressure, or whether the exhaust temperature reaches a third exhaust temperature. And when any one condition is met, stopping raising the frequency of the air conditioner, and setting the frequency of the air conditioner at the moment as the regulated frequency.
For example, the current frequency of the air conditioner is 95Hz, the third upper limit frequency is 100Hz, the first speed is 1Hz adjusted up every 15s, and the first exhaust pressure is 3.2MPa. If the obtained length of the connecting pipe is within the third specification D, the upper limit of the frequency of the air conditioner is set to be 100Hz, and then the air conditioner is started to be up-regulated at the speed of 1Hz every 15 s. And monitoring whether the exhaust pressure of the compressor is more than 3.2MPa or not while the air conditioner is subjected to frequency boosting. And if the discharge pressure of the compressor is detected to be more than 3.2MPa after 30s, taking 97Hz as the frequency after regulation.
Optionally, the indoor unit further includes an inner motor, the outdoor unit includes an outer motor, and after the frequency of the air conditioner is the adjusted and controlled frequency when it is determined that the exhaust pressure is greater than a second exhaust pressure or the exhaust temperature reaches a third exhaust temperature, the method further includes:
and judging whether the frequency of the air conditioner reaches the fourth upper limit frequency.
And if the regulated and controlled frequency is smaller than the fourth upper limit frequency, starting at any next moment, detecting whether the rotating speed of the inner motor reaches the preset rotating speed of the inner motor within a third time period, and detecting whether the exhaust pressure reaches a third exhaust pressure.
If not, the inner motor is accelerated according to a preset acceleration speed until the rotating speed of the inner motor reaches the preset inner motor rotating speed or the exhaust pressure reaches a third exhaust pressure.
And determining that the frequency of the air conditioner is the regulated and controlled frequency when the rotating speed of the inner motor reaches the preset rotating speed of the inner motor or the exhaust pressure reaches the third exhaust pressure.
If the regulated frequency does not reach the fourth upper limit frequency yet.
Then, starting at any time, detecting whether the rotating speed of the outer motor is reduced to a preset outer motor rotating speed within a fourth time period, and detecting whether the return air pressure of the compressor is reduced to a preset return air pressure.
If not, the speed of the outer motor is reduced according to a preset speed reduction speed until the rotating speed of the outer motor is reduced to the preset rotating speed of the outer motor, or the air return pressure is reduced to a preset air return pressure.
And determining that the frequency of the air conditioner is the regulated and controlled frequency when the rotating speed of the outer motor is reduced to the preset rotating speed of the outer motor or the return air pressure is reduced to the preset return air pressure.
When the set exhaust pressure is greater than the second exhaust pressure, or the set exhaust temperature reaches the third exhaust temperature, if the frequency of the air conditioner still cannot reach the fourth upper limit frequency (i.e., the highest frequency), it may be considered whether the rotation speed of the internal motor of the internal machine is insufficient. Therefore, it is possible to detect whether the rotation speed of the inner motor reaches the preset inner motor rotation speed (developer set value) and simultaneously detect whether the exhaust pressure reaches the third exhaust pressure (preset value) for the third period of time (developer set value) starting at any subsequent time. If both the air conditioning frequency and the air conditioning frequency are not met, the speed of the inner motor is increased according to the preset increasing speed, and the air conditioning frequency correspondingly increases while the speed of the inner motor is increased. And when the rotating speed of the inner motor reaches the preset rotating speed of the inner motor or the exhaust pressure reaches the third exhaust pressure, stopping accelerating the rotating speed of the inner motor, and taking the frequency of the air conditioner at the moment as the regulated frequency.
For example, the fourth upper limit frequency is 105Hz, the current rotation speed of the internal motor is 1000r/min, the current frequency of the air conditioner is 100Hz, the preset rotation speed of the internal motor is 1200r/min, the third duration is 5s, and the preset lifting speed is 50r/min every 5 s. After the discharge pressure is set to be greater than the second discharge pressure or the discharge temperature is set to reach the third discharge temperature, the frequency of the air conditioner still cannot reach the fourth upper limit frequency. It is possible to start at any next timing to detect whether the speed of the inner motor reaches 1200r/min and the exhaust pressure reaches the third exhaust pressure within 5 s. If the air-conditioning frequency does not reach the preset value, the rotating speed of the inner motor is increased to 1050r/min, the rotating speed of the inner motor and the exhaust temperature are detected for the next 5s in … … until the rotating speed of the inner motor reaches 1200r/min or the exhaust temperature reaches the third exhaust temperature, and the air-conditioning frequency at the moment is 104Hz and serves as the frequency after regulation.
When the speed of the inner motor is increased, the speed of the outer motor can be reduced at the same time so as to reduce the return air pressure of the compressor. If the air conditioning frequency still cannot reach the highest frequency (namely the fourth upper limit frequency) after the rotating speed of the inner motor is adjusted, the rotating speed of the outer motor can be adjusted. And detecting whether the rotating speed of the outer motor is reduced to the rotating speed of the outer motor preset by the developer within a fourth time length (which can be the same as or different from the third time length) set by the developer, and monitoring whether the return air pressure is reduced to the preset return air pressure preset by the developer. If the two conditions are not met, the outer motor can be decelerated according to a preset deceleration until the rotating speed of the outer motor is decelerated to a preset rotating speed of the outer motor or the return air pressure is reduced to a preset return air pressure, and the frequency of the air conditioner at the moment is used as the regulated frequency.
For example, the fourth upper limit frequency is 106Hz, the current rotation speed of the external motor is 1100r/min, the current frequency of the air conditioner is 102Hz, the preset rotation speed of the external motor is 900r/min, the preset return air pressure is 2.8MPa, the fourth duration is 6s, and the preset down-regulation speed is 50r/min down-regulated every 6 s. After the rotation speed adjustment of the inner motor, the frequency of the air conditioner still cannot reach the fourth upper limit frequency. Then starting at any next moment, and detecting whether the speed of the outer motor is reduced to 900r/min within 6 s; meanwhile, whether the return air pressure is reduced to 2.8MPa or not is detected. If the two are not satisfied, the rotating speed of the outer motor is reduced to 1050r/min, the rotating speed of the outer motor and the return air pressure are detected for the next 5s … … until the rotating speed of the outer motor is reduced to 900r/min or the return air pressure is reduced to 2.8MPa, and the air conditioning frequency at the moment is 105Hz and serves as the regulated frequency.
In the process of adjusting the air conditioning frequency, as long as the air conditioning frequency reaches the highest frequency, any adjustment of the air conditioning frequency is stopped, so that the air conditioner is kept operating at the highest frequency.
And after the regulated and controlled frequency of the air conditioner is determined, executing step S04, and controlling the air conditioner to operate according to the regulated and controlled frequency.
