The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the air that has been conditioned and heat-exchanged.
The compressor compresses a refrigerant gas in a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.
The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a cooling effect by heat-exchanging with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioner can adjust the temperature of the indoor space throughout the cycle.

Sa10, if the judgment result of the step Sa9 is 'yes', judging whether the time delay is more than 3 min; if the determination result at step Sa9 is "no", the process returns to step Sa 8.
It should be noted that, when the delay time is greater than or equal to 3min, it indicates that the compressor needs to wait for 3min after being stopped and restarted, so that the compressor can be well protected.
If the judgment result of the step Sa10 is "YES", returning to the step Sa 8; if the determination result at step Sa10 is "no", step Sa10 is executed again.
Therefore, by executing the steps Sa2-Sa10 in the cooling mode, the energy consumption of the air conditioner can be reduced while ensuring the use comfort of users.
In some embodiments of the present invention, after determining that the outdoor ambient temperature is greater than the first temperature threshold, and further determining that the indoor ambient temperature is equal to or less than the second temperature threshold, the air conditioner is controlled to enter the air supply mode. For example, the outdoor environment temperature Tout is more than 24 ℃, the indoor environment temperature Tin is less than or equal to 28 ℃,
in the embodiment, control parameters in the air supply mode are acquired, and the state of an indoor environment adjusting component of the air conditioner is controlled according to the control parameters. The control parameters may include compressor parameters, indoor fan parameters, transverse air deflectors parameters, longitudinal air deflectors parameters, and the like, for example, compressor shutdown parameters. Thereby realizing the control of the state of the indoor environment adjusting part of the air conditioner.
The following describes in detail a control method of an air conditioner according to an embodiment of the present invention, when the comfort operation mode is an air supply mode, with reference to fig. 2, where the air supply mode is different from the cooling mode, where the indoor temperature range is different, the operation state of the indoor fan needs to be controlled differently, and the air supply mode may be the same as the normal cooling mode, as follows.
Sa1, starting a TMS function by the air conditioner;
sb2, determining that the air conditioner enters a fourth temperature zone and operates an air supply mode according to Tout, Tin and Rh;
specifically, in step Sb2, it is determined that Tout is greater than 24 ℃, the air conditioner enters the fourth temperature zone, and Tin is less than or equal to 28 ℃, the air conditioner enters the air supply mode, and at this time, the air conditioner operates only in the air supply mode and continuously supplies air to the room.
Sb3, determine whether the operating time is 30s or more. For example, if the judgment result of step Sb3 is yes, Tout, Tin, and Rh are redetected; if the judgment result in the step Sb3 is "no", the flow returns to the step Sb2 to continue the air supply.
Therefore, the energy consumption of the air conditioner can be reduced while ensuring the use comfort of the user through the steps Sb2-Sb 3.
The adjustment of the state of the indoor environment adjusting member at the time of the air blowing mode in the embodiment of the invention is described below. In some embodiments of the present invention, the air conditioner enters a blowing mode, and the indoor environment conditioning components of the air conditioner include at least one of a compressor, an indoor fan, a transverse air deflector, and a longitudinal air deflector. For example, Tout > 24 ℃ and Tin ≦ 28 ℃.
The operation state of the indoor fan, the operation state and frequency of the compressor, the operation state of the electric heater, the horizontal air deflector, the vertical air deflector, etc. in the blowing mode are shown in table 1.
In an embodiment, in the blowing mode, controlling a state of an indoor environment adjusting part of the air conditioner according to a control parameter includes at least one of: controlling the compressor to stop running; controlling an indoor fan to run at a mute wind level; controlling the crosspiece air deflector to the position with the adjustable minimum opening degree; and controlling the longitudinal air deflector to an intermediate position between the adjustable minimum opening position and the adjustable maximum opening position.
Specifically, as shown in table 1, when the air conditioner operates in the air supply mode, the indoor fan operates in a silent wind range, for example, the wind wheel of the indoor fan is controlled to operate at the lowest rotation speed, the maximum rotation speed of the wind wheel is 600 rpm, and breeze is sent out indoors, so that noise interference of the air conditioner can be effectively reduced, and high comfort of a user is ensured. The transverse air guide plate is controlled to be at the adjustable minimum opening position, namely the upward maximum opening position, cold air can be continuously sent to the upper area of the indoor space, the cold air is then lowered to the space below from the upper area of the indoor space, the indoor environment temperature Tin of each area is the same, meanwhile, the indoor environment temperature Tin can be gradually raised, and the situation that the indoor environment temperature Tin is too low due to air supply is avoided. The vertical center of the longitudinal air deflector is controlled, air supply in a single direction is kept, and the problem of uneven cooling of the whole room caused by air supply in the single direction is not considered due to small air speed. Therefore, when the air conditioner runs in the air supply mode, only the fan operates, a small amount of air can flow into the room from the outside, so that the indoor air flow can be enhanced, and the energy consumption of the air conditioner can be reduced.
In a further embodiment of the present invention, the comfort stage target temperature in the cooling mode is obtained according to the outdoor ambient temperature Tout and the indoor ambient relative humidity Rh, and a method of obtaining the comfort stage target temperature in the cooling mode according to an embodiment of the present invention is described in detail below with reference to fig. 3.
Sq1, according to the indoor environment relative humidity Rh, searching a comfort stage target temperature initial value in the refrigeration mode in a comfort temperature and humidity reference table established based on the temperature and the humidity.
In the step Sq1, the comfort temperature and humidity reference table is calculated based on the currently internationally recognized human thermal comfort evaluation index pmv (predicted Mean volume) predicted average thermal sensation index value, and is obtained through calculation. In a comfort temperature and humidity reference table, the PMV value is +/-0.5. A comfort temperature and humidity reference table according to an example of the present invention is shown in table 2.
It should be noted that PMV is the predicted average heat sensation index, and the PMV evaluation index includes 4 environmental factors and 2 human factors. Wherein, the 4 environmental factors may include air temperature, humidity, air flow rate and average radiation temperature; the 2 human factors may include human metabolic rate and clothing thermal resistance.

Sq2, inquiring a temperature compensation value table according to the temperature zone to which the outdoor environment temperature belongs, the clothing thermal resistance clo and the human body metabolic rate M, and determining the comfortable temperature compensation value T under the temperature zone to which the outdoor environment temperature belongsSupplement deviceAnd the temperature compensation value table is a data table for determining temperature compensation values based on different temperature zones, thermal resistance clo of the clothes and human body metabolic rate M.
It is understood that, in the above steps, when the outdoor ambient temperature Tout is different, the comfort temperature zone and the comfort operation mode into which the air conditioner enters are different. The comfort operation mode may include a heating mode, a cooling mode, a dehumidifying mode, and an air blowing mode, among others. For example, when Tout is high, the air conditioner enters a cooling mode, and when Tout is low, the air conditioner enters a heating mode. When the comfort operation mode is the blowing mode, the above steps may not be performed.
The comfort temperature zone can be multiple. For example, as shown in table 3, the comfort temperature zones may be four, and the four comfort temperature zones may be a first temperature zone, a second temperature zone, a third temperature zone, and a fourth temperature zone, respectively. When Tout is less than or equal to 13 ℃, the air conditioner can enter a first temperature area, and when Tout is more than 13 ℃ and less than or equal to 18 ℃, the air conditioner enters a second temperature area; when Tout is more than 18 ℃ and less than or equal to 24 ℃, the air conditioner enters a third temperature zone; when Tout is more than 24 ℃, the air conditioner enters a fourth temperature zone. It can be understood that the number of the comfortable temperature zones and the boundary temperature for dividing the comfortable temperature zones can be specifically set according to actual requirements so as to better meet the actual application.
For example, a temperature compensation value table according to one example of the present invention is shown in table 3.
TABLE 3 temperature Compensation value Table

Sq3, and setting the initial value of the target temperature in the comfort stage and the compensation value T of the comfort temperatureSupplement deviceAnd the sum is used as the target temperature of the comfort stage in the cooling mode.
For example, in Table 3, T is when Tout ≦ 13 deg.CSupplement device-3 ℃ when the comfort stage target temperature is 3 ℃ lower than the comfort stage target temperature starting value. When Tout is less than or equal to 13 ℃, the outdoor environment temperature Tout is low, the air conditioner can enter the first temperature zone and operate the heating mode, and the initial outlet air temperature value of the air conditioner is the initial value of the target temperature in the comfort stage, so that the rapid temperature rise is realized. After the indoor temperature rises, if the initial value of the target temperature in the comfortable stage is continuously used as the air outlet temperature of the air conditioner, the indoor temperature is overhigh, and the use comfort of a user is reduced. The target temperature in the comfortable stage is 3 ℃ lower than the initial value of the target temperature in the comfortable stage, so that the indoor temperature is reasonable, and the user experience is improved. Therefore, through the steps, the indoor temperature can be adjusted to the comfortable temperature of the human body based on the clothing thermal resistance and the human body metabolic rate, so that the use comfort of a user is improved, and the requirement of the user on the comfort is met.
In some embodiments of the present invention, according to the indoor environment relative humidity Rh, in combination with fig. 4, when the target comfort operation mode is the cooling mode, the comfort stage target temperature initial value in the cooling mode is looked up in the comfort temperature and humidity reference table established based on the temperature and humidity.
And if the indoor environment relative humidity Rh is smaller than the lower limit value of the comfortable humidity in the comfortable temperature and humidity reference table, taking the lowest temperature corresponding to the lower limit value of the comfortable humidity as the initial value of the target temperature in the comfortable stage.
For example, in combination with table 2, when the indoor environment relative humidity Rh 25% is higher, in the comfort humiture reference table, the lower limit value of the comfort humidity is Rh 30%, and the indoor environment relative humidity Rh 25% is lower than the lower limit value of the comfort humidity Rh 30% in table 2. The lowest temperature corresponding to a humidity of 30% is 24.5 ℃, and 24.5 ℃ is taken as the initial value of the target temperature in the comfort stage. Therefore, when the indoor environment temperature Tin is higher, the indoor environment temperature Tin can be quickly reduced, and the use comfort of a user is improved.
And if the indoor environment relative humidity Rh is greater than the upper limit value of the comfortable humidity in the comfortable temperature and humidity reference table, taking the lowest temperature corresponding to the upper limit value of the comfortable humidity as the initial value of the target temperature in the comfortable stage.
For example, in combination with table 2, when the indoor environment relative humidity Rh 70%, in the comfort temperature and humidity reference table, the upper limit value of the comfort humidity is Rh 65%, and the indoor environment relative humidity Rh 70% is greater than the upper limit value of the comfort humidity Rh 65% in table 2. The lowest temperature corresponding to a humidity of 65% is 23.5 c, and 23.5 c is used as the initial value of the comfort stage target temperature. Therefore, when the indoor environment temperature Tin is higher, the indoor environment temperature Tin can be quickly reduced, and the use comfort of a user is improved.
And if the indoor environment relative humidity Rh is between the lower limit value of the comfortable humidity and the upper limit value of the comfortable humidity, taking the lowest temperature corresponding to the humidity closest to the indoor environment relative humidity Rh as the initial value of the target temperature in the comfortable stage.
For example, in combination with table 2, when the indoor relative humidity Rh 34% is measured, in the comfort humiture reference table, the indoor environment relative humidity is between 30% and 65% (inclusive), the humidity closest to the indoor relative humidity Rh is 35%, and the lowest temperature corresponding to the humidity of 35% is 24.5 ℃, and then 24.5 ℃ is taken as the initial value of the target temperature for the comfort stage. Therefore, when the indoor environment temperature Tin is higher, the indoor environment temperature Tin can be quickly reduced, and the use comfort of a user is improved.
Therefore, when the air conditioner operates in the refrigeration mode, the initial value of the target temperature in the comfortable stage can be more accurate, so that the indoor environment temperature Tin can be effectively adjusted to the comfortable temperature, and the comfort level of a user is improved.
In some embodiments of the present invention, in conjunction with fig. 5, when the target comfort operation mode is the heating mode,
and if the indoor environment relative humidity Rh is smaller than the lower limit value of the comfortable humidity in the comfortable temperature and humidity reference table, taking the highest temperature corresponding to the lower limit value of the comfortable humidity as the initial value of the target temperature in the comfortable stage.
For example, in combination with table 2, when the indoor environment relative humidity Rh 25% is higher, in the comfort humiture reference table, the lower limit value of the comfort humidity is Rh 30%, and the indoor environment relative humidity Rh 25% is lower than the lower limit value of the comfort humidity Rh 30% in table 2. The maximum temperature corresponding to a humidity of 30% is 27 c, and 27 c is taken as the initial value of the comfort stage target temperature. Therefore, when the indoor environment temperature Tin is low, the indoor environment temperature Tin can be quickly increased, and the use comfort of a user is improved.
And if the indoor environment relative humidity Rh is greater than the upper limit value of the comfortable humidity in the comfortable temperature and humidity reference table, taking the highest temperature corresponding to the upper limit value of the comfortable humidity as the initial value of the target temperature in the comfortable stage.
For example, in combination with table 2, when the indoor environment relative humidity Rh 70%, in the comfort temperature and humidity reference table, the upper limit value of the comfort humidity is Rh 65%, and the indoor environment relative humidity Rh 70% is greater than the upper limit value of the comfort humidity Rh 65% in table 2. The maximum temperature corresponding to a humidity of 65% is 26 ℃, and 26 ℃ is taken as the initial value of the target temperature for the comfort phase. Therefore, when the indoor environment temperature Tin is low, the indoor environment temperature Tin can be quickly increased, and the use comfort of a user is improved.
And if the indoor environment relative humidity Rh is between the lower limit value of the comfortable humidity and the upper limit value of the comfortable humidity, taking the highest temperature corresponding to the humidity closest to the indoor environment relative humidity as the initial value of the target temperature in the comfortable stage.
For example, in combination with table 2, when the indoor relative humidity Rh 43% is measured, in the comfort humiture reference table, the indoor environment relative humidity is between 30% and 65% (inclusive), the humidity closest to the indoor relative humidity Rh is 45%, and the maximum temperature corresponding to the humidity of 45% is 26.5 ℃, and then 26.5 ℃ is taken as the initial value of the target temperature in the comfort stage. Therefore, when the indoor environment temperature Tin is low, the indoor environment temperature Tin can be quickly increased, and the use comfort of a user is improved.
Therefore, when the air conditioner operates in a heating mode, the initial value of the target temperature in the comfort stage can be more accurate, so that the indoor environment temperature Tin can be effectively adjusted to the comfort temperature, and the comfort level of a user is improved.
In some embodiments of the invention, the temperature settings for the three comfort phases in the cooling mode are as follows: in the initial comfort stage of cooling, the target temperature of the comfort stage is set as the target temperature Ts of the initial comfort stageBeginningAt an initial comfort stage target temperature TsBeginningAnd controlling the air conditioner to operate. For example, when the indoor relative humidity Rh 34% is combined with Table 2, Ts can be obtainedBeginning24.5 ℃. In the initial comfortable stage of refrigeration, the indoor ambient temperature Tin can be rapidly reduced to rapidly adjust the indoor ambient temperature Tin to the comfortable temperature of the human body.
In the cooling stable comfort phase, the target temperature Ts in the initial comfort phaseBeginningGradually increasing until the target temperature Ts is stabilized in the comfort stage'Jieshu' for treating rheumatismEqual, stable comfort stage target temperature Ts'Jieshu' for treating rheumatismFor an initial comfort phase target temperature TsBeginningAnd comfort temperature compensation value TSupplement deviceAnd (4) summing. From this, in the comfortable stage of refrigeration stability, indoor ambient temperature Tin slowly increases progressively to can adjust the temperature gradually to human comfortable temperature, thereby satisfy the requirement of user to the comfort level.
In the cooling health and comfort stage, the target temperature Ts in the stable comfort stage'Jieshu' for treating rheumatismGradually increasing until the target temperature is equal to Ts in the healthy and comfortable stageJointTarget temperature Ts during healthy and comfortable periodJointTo stabilize the comfort stage target temperature Ts'Jieshu' for treating rheumatismAnd the sum of the adjusted temperature values. Therefore, the use comfort of the user is ensured in the stage of refrigeration, health and comfortAt the same time, the temperature can be adjusted to a healthy and comfortable stage target temperature Ts which is beneficial to human healthJointAnd the user is prevented from getting 'air conditioner diseases'.
In a further embodiment of the present invention, in the initial comfort stage of cooling, if the first set temperature difference is less than or equal to the first predetermined temperature and the duration reaches the first predetermined time, or the second set temperature difference is less than or equal to the second predetermined temperature and the duration reaches the second predetermined time, the cooling stable comfort stage is entered.
Wherein the first set temperature difference is the indoor environment temperature Tin and the target temperature Ts in the initial comfort stageBeginningThe second set temperature difference is the indoor ambient temperature Tin and the stable comfort stage target temperature Ts'Jieshu' for treating rheumatismThe difference of (a).
For example, when the comfort operation mode is the cooling mode, when the absolute value of the second set temperature difference is less than or equal to the second predetermined temperature and the duration reaches the second predetermined time, the temperature of the cooling initial comfort stage is not reached, but the temperature of the cooling stable comfort stage is reached. When the first set temperature difference is less than or equal to the first preset temperature and the duration time reaches the first preset time, the indoor environment temperature Tin is already reduced to be close to the target temperature Ts in the initial comfort stage of refrigerationBeginningIf continuing to cool the initial comfort stage target temperature TsBeginningIn operation, the indoor ambient temperature Tin may be too low. Therefore, the refrigerating stable and comfortable stage is started when the first set temperature difference is smaller than or equal to the first preset temperature and the duration time reaches the first preset time, and the user can be guaranteed to have higher comfort. Alternatively, the first predetermined temperature and the second predetermined temperature may both be 0.5 ℃, the first predetermined time may be 5min, and the second predetermined time may be 15 min. But is not limited thereto.
Further, in the refrigerating stable and comfortable stage, if the first set temperature difference is less than or equal to the negative first preset temperature and the duration reaches a third preset time, the refrigerating healthy and comfortable stage is entered. Alternatively, the third predetermined time may be 30 min. For example, when the comfort operation mode is the cooling mode, the indoor ambient temperature Tin and the initial comfort stage target areTemperature TsBeginningThe difference of (a). When the first set temperature difference is less than or equal to the negative first predetermined temperature, it indicates that the indoor ambient temperature Tin is too low. Therefore, the refrigeration health and comfort stage is started when the first set temperature difference is smaller than or equal to the negative first preset temperature and the duration time reaches the third preset time. When comfortable operation mode is the refrigeration mode, can avoid indoor ambient temperature Tin to hang down excessively, when guaranteeing that the user has higher comfort level, be favorable to user's healthy.
In some embodiments of the invention, in the comfort temperature and humidity reference table, an average value of a sum of a lower comfortable temperature limit value and an upper comfortable temperature limit value corresponding to the comfortable humidity of the human body is used as the target temperature Ts in the stable comfort stage'Jieshu' for treating rheumatism. For example, when the comfortable humidity of the human body is 50%, the lower limit value of the comfortable temperature corresponding to the comfortable humidity of the human body is 24 ℃, the upper limit value of the comfortable temperature is 26.5 ℃, the average value of the sum of the lower limit value of the comfortable temperature and the upper limit value of the comfortable temperature is 25.25 ℃, and since the comfortable temperature and humidity reference table does not have 25.25 ℃, 25.5 ℃ close to 25.25 ℃ is taken as the stable comfortable stage target temperature Ts _ comfort. By the arrangement, the target temperature Ts _ comfortable in the stable and comfortable stage can be prevented from being too high or too low, so that the target temperature Ts _ comfortable in the stable and comfortable stage is the comfortable temperature of a human body, and the use comfort of a user can be further improved.
In some embodiments of the present invention, when the air conditioner operates in the cooling mode for the fourth predetermined time, the outdoor ambient temperature Tout and the indoor ambient temperature Tin are newly acquired, and the temperature zone to which the outdoor ambient temperature belongs is newly determined.
And if the temperature zone to which the newly determined outdoor environment temperature Tout belongs is the same as the temperature zone to which the outdoor environment temperature Tout belongs last time, and the indoor environment temperature is greater than the second temperature threshold, continuing to operate in the cooling mode.
And if the temperature zone to which the newly determined outdoor environment temperature Tout belongs is different from the temperature zone to which the outdoor environment temperature Tout belongs last time, determining a new comfortable operation mode according to the newly obtained outdoor environment temperature Tout and the indoor environment temperature Tin.
Specifically, the fourth predetermined time may be two hours. The comfort operation mode is re-determined every two hours according to the outdoor ambient temperature Tout. For example, when Tout is detected to be more than 24 ℃, the operation temperature zone is still the fourth temperature zone, and Tin is more than 28 ℃, the refrigeration mode and the stage operation are continuously maintained; if Tout is less than 24 ℃, the operation is carried out in a new temperature zone, and the original operation mode is interrupted and the operation is carried out in a new specific mode by combining the indoor environment temperature Tin of the new temperature zone, which is different from the temperature zone belonging to the previous time. Therefore, through the arrangement, when the outdoor environment temperature Tout changes, the comfortable operation mode can be timely changed according to the outdoor environment temperature Tout, and the use comfort of a user can be ensured.
Optionally, the indoor ambient temperature Tin is an indoor instantaneous sampling ambient temperature, and a sampling period of the indoor instantaneous sampling ambient temperature may be 5 min.
