Referring to fig. 1 and 2 in combination, according to an embodiment of the present invention, a control method of an air conditioner includes: controlling the air conditioner to enter a comfort control mode; controlling an air conditioner to adjust the indoor temperature to a set temperature; determining a current PMV value; and adjusting the set temperature, the relative humidity and the wind speed according to the determined PMV value.

The step of controlling the air conditioner to adjust the indoor temperature to the set temperature includes: acquiring the current indoor temperature; detecting a temperature deviation between the current indoor temperature and a set temperature; and adjusting the indoor temperature according to the temperature deviation. Preferably, the step of adjusting the indoor temperature according to the temperature deviation is implemented by PID (proportional integral derivative) control.
Through detecting the temperature deviation between the current indoor temperature and the set temperature, the rapid adjustment of the indoor temperature can be realized according to the temperature deviation, so that the indoor temperature can be rapidly adjusted to the set temperature. In this embodiment, the indoor temperature is adjusted by PID control, which can accurately control the indoor temperature by PID control, thereby improving the indoor temperature adjustment efficiency. Of course, the indoor temperature may be adjusted by PI (proportional integral) control, PD (proportional differential) control, or the like.
After the indoor temperature reaches the set temperature, although the temperature reaches the requirement of the user, factors in various aspects such as the indoor wind speed, the temperature, the humidity and the radiation temperature may not be adjusted in place, so that the PMV value is out of the set range, the phenomenon of user discomfort still occurs at the moment, meanwhile, the problems of low operation efficiency of the air conditioner and the like are caused, the purpose of energy conservation is difficult to achieve, and the energy efficiency ratio of the air conditioner is reduced. Therefore, at this time, the set temperature needs to be adjusted again, and the relative humidity and the wind speed need to be adjusted accordingly, so that the finally obtained PMV value reaches the set PMV value range, and the relative humidity and the wind speed can be in a better numerical value range, so that the indoor environment is in a comfortable range, and a user obtains better use experience.
In this embodiment, the step of adjusting the set temperature, the relative humidity and the wind speed according to the determined PMV value includes: when PMV is greater than T1, controlling the set temperature to fall by a ℃; when PMV is less than T2, controlling the set temperature to rise by b ℃; when the PMV is more than or equal to T2 and less than or equal to T1, the current set temperature is kept, and the relative humidity is adjusted according to the detected relative humidity; when the relative humidity is adjusted to a set range, adjusting the rotating speed of the fan according to the detected wind speed; the PMV was checked every t 1. The set temperature is adjusted once per detection, and is also adjusted once in one detection period. For example, when the PMV > T1 is detected for the first time, the set temperature is controlled to drop a ℃ once, and then the PMV value is detected again at time T1, if the PMV > T1 is still detected, the set temperature is controlled to drop a ℃ once again in the period, so that the adjustment of the set temperature can ensure that the PMV value is gradually adjusted to be in the comfort range.
When the set temperature is adjusted in place, the step of adjusting the relative humidity according to the detected relative humidity comprises the following steps: controlling the relative humidity to be reduced by c% when the relative humidity RH is detected to be more than H1; when the relative humidity RH is detected to be less than H2, controlling the relative humidity to rise by d percent; when the relative humidity H2 is detected to be more than or equal to RH and less than or equal to H1, the relative humidity is not adjusted; RH was measured every t 2.
After the set temperature is adjusted in place, the PMV value at the moment is adjusted in place, but because the influence on the PMV value is a plurality of parameters, the indoor humidity can be difficultly ensured and the comfort requirement can be met at the same time, so that the relative humidity RH can be adjusted at the moment, and the aim is to ensure that the indoor humidity can be in the comfort range of the user and further improve the comfort experience of the user.
After the relative humidity is adjusted to a preset range, the step of adjusting the rotating speed of the fan according to the detected wind speed comprises the following steps: when the wind speed V is detectedASWhen the current time is more than e, controlling the rotating speed of the fan to reduce frpm; when the wind speed V is detectedASWhen the rotation speed is less than or equal to e, controlling the fan to keep the current rotation speed; every t3 time pairs VASAnd carrying out one detection.
When the set temperature and the relative humidity are adjusted in place, the PMV value at the moment is also adjusted in place, if the wind speed at the moment is high, although the indoor environment is still in the human body comfort level range, the human body still has a strong blowing feeling, the use feeling of the human body is affected, and particularly the comfort level of the human body is affected when the human body is in a sleep state. Therefore, although the PMV value is already adjusted in place at this time, and the set temperature and the relative humidity are also in a better state, the wind speed still needs to be adjusted, so that the wind speed is reduced, the wind speed is controlled to be a smaller value, no wind sensation or slight wind sensation is realized, the comfortable feeling of a human body is further improved, the working frequency of the fan is reduced, and energy is saved.
The above-mentioned T1 is, for example, 0.5, T2 is, for example, -0.5, T1 is, for example, 10 minutes, T2 is 10 minutes, T3 is 2 minutes, H1 is 60%, H2 is 30%, a is, for example, 0.4, b is, for example, 0.4, c is 5, d is 5, e is 0.5m/s, and f is 20. Of course, the above numerical values may be adjusted according to needs, and may be specifically set according to models and the like.
When the air conditioner detects the indoor temperature once every 10 minutes, the indoor temperature can be adjusted by adjusting the running frequency of the compressor, the rotating speed of the fan and/or the opening of the throttle valve, and when different parameters are selected, the control strategy can be correspondingly adjusted.
When the indoor temperature is adjusted by adjusting the operating frequency of the compressor, the step of adjusting the indoor temperature according to the temperature deviation includes: detecting the current compressor running frequency; and adjusting the running frequency of the compressor according to the temperature deviation.
The step of adjusting the indoor temperature according to the temperature deviation includes: detecting the current wind speed; and adjusting the wind speed according to the temperature deviation.
The step of determining the current PMV value comprises: acquiring current indoor temperature, wind speed, relative humidity and radiation temperature; the current PMV is determined from the indoor temperature, wind speed, relative humidity and radiation temperature.
Wherein, the current PMV is determined according to the indoor temperature, the wind speed, the relative humidity and the radiation temperature according to the following formula:
wherein, M is the metabolic rate, unit: w/s; w is the power of human body, unit:
is the partial pressure of water vapor in ambient air, unit: pa; t is taIs the indoor temperature in units; f. ofclThe ratio of the surface area of the dressed human body to the surface area of the naked body;
average radiant temperature in units; t is tclAverage temperature of the outer surface of the human body after dressing in unit; h iscConvective heat transfer coefficient, W/s.m2℃。
The M range is: 116 to 197.258W/m2. W is typically taken to be 0.
Partial pressure P of water vapor in ambient airaCalculated according to the following formula:
Pa＝φa.Ps

the ratio f of the surface area of the body to the surface area of the naked bodyclCalculated according to the following formula:
wherein IclFor clothing thermal resistance, 0.9clo is generally adopted in winter, 0.5clo is adopted in summer, and 0.155k.m is adopted in 1clo in northern part2/w。
Mean radiant temperature
On the premise of ensuring the stability of the PMV value, the average radiation temperature and the indoor temperature are in inverse proportion, and the influence of the indoor temperature on the PMV value is larger.
Average temperature t of outer surface of dressed human bodyclCalculated according to the following formula:
wherein,
surface heat transfer coefficient hcCalculated according to the following formula:
wherein V is the wind speed. Wind speed v is less than 0.15m/s in winter, and less than 0.25m/s in summer, and is generally 0.15m/s in winter and 0.25m/s in summer.
There are generally 6 factors affecting the thermal comfort of the human body: indoor temperature, wind speed, relative humidity, radiation temperature, human body metabolic rate and clothing thermal resistance. And the human body metabolic rate and the clothing thermal resistance are generally set as constants when designing the air conditioner. Therefore, the current PMV can be determined according to the indoor temperature, the wind speed, the relative humidity and the radiation temperature, and the indoor temperature and the relative humidity are adjusted, so that the PMV is in a range that a human body feels comfortable, and the comfort of the operation of the air conditioner is improved.
After the current PMV value is determined, the step of adjusting the set temperature, the relative humidity and the wind speed according to the determined PMV value further comprises the following steps: acquiring temperature compensation information, humidity compensation information or wind speed compensation information; compensating the current indoor temperature according to the temperature compensation information, compensating the current relative humidity according to the humidity compensation information, or compensating the current wind speed according to the wind speed compensation information; and determining the current PMV value according to the adjusted indoor temperature, the adjusted relative humidity or the adjusted wind speed. When the air conditioner adjusts the set temperature, the relative humidity or the wind speed according to the PMV, the situation that the set temperature is actively adjusted by a user may be met, for the situation, the temperature adjustment quantity of the user can be obtained and then is used as temperature compensation information, humidity compensation information or wind speed compensation information, the PMV is calculated by combining the current set temperature, the current relative humidity or the current wind speed together as a calculation parameter of the PMV, so that the PMV can be adjusted simultaneously by combining the needs of the user, the indoor temperature, the relative humidity or the wind speed can be quickly and accurately adjusted in real time, the indoor temperature, the relative humidity or the wind speed can be adjusted to better meet the differentiation needs of each user, and the user can obtain better use experience.
The step of controlling the air conditioner to enter the comfort control mode includes: starting the air conditioner; setting a set temperature; controlling the air conditioner to operate for t4 time until the air conditioner stably operates; and controlling the air conditioner to enter a comfort control mode. During the initial start-up of the air conditioner, the operation of the air conditioner is unstable, and thus it is not necessary to control the air conditioner to enter the comfort control mode at this time. After the air conditioner operates for t4 time, each operating parameter is stabilized, and the indoor temperature reaches the set temperature stably, the comfort control mode of the air conditioner can be started, so that the air conditioner determines whether the operating parameters of the air conditioner need to be adjusted according to the PMV value obtained by the current indoor temperature, and the more energy-saving and efficient air conditioner operation effect can be obtained. T4 here is, for example, 30 min.
The control method of the air conditioner of the present invention is explained with reference to fig. 2 as follows:
firstly, the air conditioner receives a set temperature, then adjusts the frequency of the compressor by taking the set temperature as a target through a PID control mode, then obtaining corresponding temperature variation, wind speed variation and relative humidity variation according to the adjusted compressor frequency, obtaining the adjusted actual temperature value, then returning the regulated actual temperature to the set temperature for comparison, regulating the running frequency of the compressor according to the comparison result until the indoor temperature is regulated to the set temperature range, then obtaining the current indoor temperature, wind speed, relative humidity, radiation temperature and the like, obtaining the PMV value under the current operating environment according to the current indoor temperature, wind speed, relative humidity, radiation temperature and the like, and then determining a set temperature value to be adjusted according to the PMV value, and transmitting the temperature correction value to the current set temperature so as to adjust the current set temperature. After the set temperature is adjusted once according to the current PMV value, the indoor temperature is detected again after 10 minutes, the corresponding PMV value is obtained, and then the set temperature is adjusted again according to the PMV value, so that the circulation adjustment is carried out, and the indoor environment can be always maintained in the optimal comfort range.
After the set temperature is adjusted in place, the PMV value at the moment is adjusted in place, but the influence on the PMV value is a plurality of parameters, so that the indoor humidity cannot be guaranteed to meet the comfort requirement, and the relative humidity RH is required to be adjusted at the moment, so that the relative humidity of the indoor environment can be in a reasonable range on the basis of meeting the comfort requirement.
When the set temperature and the relative humidity are adjusted in place, the PMV value at the moment is also adjusted in place, if the wind speed at the moment is high, although the indoor environment is still in the human body comfort level range, the human body still has a strong blowing feeling, the use feeling of the human body is affected, and particularly the comfort level of the human body is affected when the human body is in a sleep state. Therefore, although the PMV value is already adjusted in place at this time, and the set temperature and the relative humidity are also in a better state, the wind speed still needs to be adjusted, so that the wind speed is reduced, the wind speed is controlled to be a smaller value, no wind sensation or slight wind sensation is realized, the comfortable feeling of a human body is further improved, the working frequency of the fan is reduced, and energy is saved.
It is to be understood that the present invention is not limited to the procedures and structures described above and shown in the drawings, and that various modifications and changes may be made without departing from the scope thereof. The scope of the invention is limited only by the appended claims.
