Detailed description of the invention
Technical scheme of the present invention is further illustrated below in conjunction with Figure of description and specific embodiment.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
The present invention proposes a kind of pleasant climate method of air-conditioner, be control objectives with comfort index, air-conditioner is controlled.As shown in Figure 1, comfort index is the evaluation index of being taught the sign human thermal response (warm-cold sensitivity) proposed by the Fan Geer of Denmark (P.O.Fanger), comprises six parameters: air themperature, air humidity, wind speed, radiation temperature, clothing thermal resistance and body metabolism rate.Fanger, through the test of a large amount of data researches and different object, has drawn a comfortableness equation.After obtaining these six parameters, by Fanger comfortableness equation, just can calculate and obtain corresponding comfort level.Such as, cold (-3), cool (-2), slightly cool (-1), neutral (0), slightly warm (1), warm (2), heat (3).
Above-mentioned comfortableness equation is as follows:
Wherein, M---body metabolism rate;
W---human body power (general value is 0);
Pa---steam partial pressure in surrounding air,
for relative humidity, wherein:
Ta---air themperature is also indoor environment temperature;
F
cl---the ratio on wear the clothes human body and nude surface:
---mean radiant temperature;
T
cl---be people's external surface mean temperature of wearing the clothes:
H
c---surface coefficient of heat transfer:
As shown in Figure 2, the pleasant climate method of the air-conditioner of the present embodiment comprises the following steps:
S11, detect air-conditioner open pleasant climate time, obtain indoor initial temperature;
This indoor initial temperature can be detected by the temperature sensor being arranged on air-conditioner return air inlet place and obtain, and also can be detected by the temperature sensor being arranged on appropriate position in room and obtain.If the temperature at air-conditioner return air inlet place detected, then in order to the accuracy of indoor initial temperature, this temperature sensor acquisition indoor temperature can be raised or lower one and be worth accordingly, to obtain indoor initial temperature.
S12, according to described indoor initial temperature, when obtaining described indoor initial temperature, the target indoor temperature that target comfort level is corresponding;
By Fanger comfortableness equation, when five parameters supposing in six parameters except indoor temperature are all definite values, then the corresponding relation between comfort level and indoor temperature can be derived.And the corresponding relation between this comfort level and indoor temperature is also by the impact of indoor initial temperature during air-conditioner operation.Therefore, will according to indoor initial temperature, when obtaining indoor initial temperature, the target indoor temperature that target comfort level is corresponding.This target comfort level can be arranged flexibly, and in the embodiment of the present invention, this target comfort level is preferably 0.
S13, control air-conditioner according to described target indoor temperature and run, obtain indoor Current Temperatures simultaneously;
After acquisition target indoor temperature, then using this target indoor temperature as design temperature, air-conditioner can be controlled and runs.The control of this air-conditioner can be carried out according to specific circumstances, such as, when air-conditioner is transducer air conditioning, is then run by high-frequency, to reach target indoor temperature fast.
S14, after indoor Current Temperatures reaches described target indoor temperature, obtain required parameter when comfort level calculates;
In control air-conditioner running, indoor environment temperature will be detected in real time, and after indoor environment temperature reaches target indoor temperature, then start to obtain parameter required when comfort level calculates, i.e. above-mentioned six parameters.
S15, parameter required when calculating according to the described comfort level obtained, calculate and obtain current comfort level;
Six of above-mentioned acquisition parameters are substituted into above-mentioned Fanger comfortableness equation, calculates and obtain current comfort level.Due to the comfort level that this current comfort level obtained by Fanger comfortableness equation is room central point, therefore in order to accurately embody the global comfort in room, preferentially the comfort level of this room central point is added a preset comfort level adjusted value, as the comfort level mean value in room in the embodiment of the present invention.
S16, when described current comfort level is in a presetting range, control air-conditioner keep current running status, and return perform step S14;
In the present embodiment, this presetting range is [-1,1].If current comfort level is in this presetting range, then control air-conditioner and keep current running status, namely the operational factor of air-conditioner does not need adjustment.
S17, when described current comfort level is not in described presetting range, adjust described target indoor temperature, and return and perform step S13.
If when current comfort level is not in this presetting range, then adjustment aim indoor temperature.Be specially: when described current comfort level is greater than maximum (such as, 1) of presetting range, described target indoor temperature is reduced a preset temperature; When described current comfort level is less than minimum of a value (such as ,-1) of presetting range, described target indoor temperature is raised a preset temperature.This preset temperature is | (PMV
current-PMV
setting) |/y; Wherein, PMV
currentfor the current comfort level that above-mentioned steps S15 calculates, also can be the PMV mean value in step S15 preferred embodiment.PMV
settingfor target comfort level.Y is then for the different indoor initial temperature of correspondence and a default numerical value.
After according to difference change adjustment aim indoor temperature, air-conditioner will control the operation of air-conditioner according to this target indoor temperature.After the indoor environment temperature in room reaches target indoor temperature, more again obtain six parameters of comfort index, calculate current comfort level, and adjust indoor objects temperature according to the difference of current comfort level and target comfort level.Progressively adjust corresponding target indoor temperature by above-mentioned, reach human body optimal comfort state with the comfort level accurately controlling air-conditioner.
Current comfort level and target comfort level, by obtaining the current comfort level in room, compare by the embodiment of the present invention, and according to both difference adjustment aim indoor temperature, the comfort level of final control air-conditioner reaches human body optimal comfort state.Therefore, the embodiment of the present invention makes the environment in room to reach and is stabilized in the most comfortable state of human body sensory.In addition, due in the embodiment of the present invention, also contemplate the impact that indoor initial temperature controls comfort level, thus it is more accurate that comfort level is controlled.
Further, when above-mentioned comfort level calculates, six required parameters can obtain in the following manner:
(1) indoor environment temperature, indoor environment humidity and radiation temperature
Indoor environment temperature and indoor environment humidity can by being arranged on temperature sensor in room and humidity sensor obtains.By being arranged on temperature sensor and the humidity sensor at air-conditioner return air inlet place, the temperature and humidity at air-conditioner return air place can certainly be detected, then according to the computation rule preset, calculating and obtaining radiation temperature, indoor environment temperature and indoor environment temperature.
During owing to heating, to up move from the hot blast of air conditioner wind outlet blowout, be arranged on the temperature of the air-conditioner return air inlet of higher position thus by higher than the mean temperature in room, the temperature of the return air inlet detected time therefore by heating deducts a preset value, can obtain indoor environment temperature.On the contrary, during refrigeration, the cold wind of air conditioner wind outlet blowout will down move, and be arranged on the temperature of the return air inlet of the air-conditioner of higher position thus by higher than the mean temperature in room, the temperature of the return air inlet detected time therefore by heating deducts a preset value, can obtain indoor environment temperature.In like manner, according to the humidity at return air inlet place and heat/preset value that refrigeration mode is corresponding adjusts, and obtains indoor environment humidity.
Radiation temperature refers to the mean radiant temperature of wall, indoor equipment etc.In the embodiment of the present invention, this radiation temperature is equal with indoor environment temperature.Can certainly carry out different adjustment according to specific circumstances, if the windowpane area in room is excessive, or the radiation of indoor equipment is excessive etc.
(2) clothing thermal resistance and metabolic rate
Clothes, between human body surface and environment, plays warming in cold season, then has good permeability in summer.Therefore the heat-insulating property of clothes and the thermal conduction characteristic of material therefor and thickness all have a certain impact to clothing thermal resistance tool, and the dress of people is relevant with indoor environment temperature.The embodiment of the present invention, by a large amount of test data research, obtains the corresponding relation of clothing thermal resistance and indoor initial temperature, and forms corresponding mapping table.
