Specific embodiment
In order to make those skilled in the art more fully understand technical solution of the present invention, combined with specific embodiments below to thisInvention is described in further detail.It note that the embodiments described below is exemplary, for explaining only the invention, andIt is not considered as limiting the invention.Particular technique or condition are not specified in embodiment, according to the literature in the art instituteThe technology or conditions of description are carried out according to product description.Reagents or instruments used without specified manufacturer, being canWith conventional products that are commercially available.
Of the invention is control method of the hotness as comfort index of user comprising: room temperature, interiorHumidity, outdoor weather conditions, room parameter, light sensation value, time are that input quantity calculates human body comfort index, and refers to comfortHeading scale value relatively determines the desired temperature and operation duration of air conditioner, realizes the thermal comfort control of air conditioner.
PMV index is exactly that will reflect that human body obtains the human body thermic load introducing of thermally equilibrated departure degree.Pmv value pointFor 6 different ranges.Ideally, pmv value 0, human body sensory the most comfortable at this time, but be difficult to be kept for one in practicePMV perseverance is 0 in period.The pmv value section of default setting thermal comfort of the present invention is [- 0.5 ,+0.5].
According to an aspect of the present invention, the present invention provides hotel room air conditioner comfort control method, Fig. 1 is thisInvention hotel room air conditioner comfort control method flow diagram, comprising:
Indoor mean radiant temperature is determined according to area, date, outdoor weather conditions and peripheral structure parameter；
Determine that human metabolism leads according to light sensation and time；
Calculating is led according to room temperature, indoor relative humidity, the mean radiant temperature and the human metabolismPmv value；
Determine the section PMV；
The pmv value and the section PMV are compared, publication airconditioning control instruction.
According to a particular embodiment of the invention, the calculation of the pmv value are as follows:
PMV=[0.303e-0.036M+0.028]{M-W-3.05×10-3[5.733-6.99(M-W)-pa]
-0.42[(M-W)-58.15]-1.7×10-5M(5867-pa)-0.0014M(34-ta)-
3.96×10-8fcl[(tcl+273)4-(ts+273)4-fclhc(tcl-ta)]}
Wherein, M is metabolic rate, W/m2；W is human body power, W/s；paFor steam partial pressure in surrounding air,Pa；taFor indoor air temperature, DEG C；fclFor human body and the nude surface area ratio of wearing the clothes；tsFor mean radiant temperature, DEG C；tclForIt wears the clothes human body outer surface mean temperature, DEG C；hcFor heat exchange coefficient, W/ (s ﹒ m2﹒ DEG C).8 variables in formula: M, W, pa、ta、fcl、ts、tcl、hc.In fact, fclAnd tclIt can be by IclDetermine (IclFor clothes/bedding thermal resistance), hcIt is the function of wind speed, paIt is taAnd RHaFunction (RHaFor the relative humidity of air), W considers by 0, and taAnd RHaIt can be with.
pa=6107.8 × RHa×exp[ta/(ta+238.2)×17.2694]
Therefore the index for influencing human thermal comfort PMV has 6, i.e. indoor air temperature；Indoor air relative humidity；It is indoorMean radiant temperature；Clothing and human metabolism lead.When winter or summer clothing/bedding determination, and it is less than the wind speed pair of 0.1m/sPMV influences very little, and wind speed is set as 0.1m/s by the present invention, according to thermal comfort equation, mean radiant temperature, air epidemic disasterLeading with human metabolism is the principal element for influencing human thermal comfort.
According to a particular embodiment of the invention, can also be according to indoor epidemic disaster, other influence factors are by the setting such as seasonConsider to calculate pmv value for constant；Or according to outdoor weather conditions (outdoor temperature and rain or shine nimbus), month and exterior wall directionDeng the influence of estimation mean radiant temperature, such as refrigeration season 7, middle of August part fine day exterior wall with a western exposure or top room the time in the afternoonSection, it is contemplated that pmv value is added certain correction value by the influence of mean radiant temperature.
According to a particular embodiment of the invention, human metabolism, which leads, to table look-up to obtain by the active state of people, generallyFor, the active state of hotel guest is mostly to stand, and sits, lies, and sleep (falls asleep, shallowly sleeps, sleep soundly, sound sleep, wakeing up), and the present invention will lead toIt crosses room light sensing magnitude and the time judges the active state of guest and then table look-up to obtain human metabolism to lead.For example, lightFeel small Mr. Yu's setting value and determine that guest turns off the light into sleep stage, then judges which of sleep guest be in by duration of turning off the lightStage.Generally, the body temperature of sleep state servant can constantly change with the deep of sleeping time, body of the human body in the stage of just falling asleepTemperature is normal body temperature usually, but is goed deep into sleeping time, and body temperature can reduce, and thermal comfort Con trolling index can be corresponding at this timeIt improves；And with the automatic adjustment of biological clock, in the stage soon wakeeed up, body temperature can be increased slowly again, and thermal comfort controls at this timeIndex can return to normal level.
According to a particular embodiment of the invention, mean radiant temperature refers to that environment surrounded surface puts down human body radiation effectEqual temperature ignores hotel guest room furniture, it is assumed that the radiant heat exchange of human body and environment is mainly derived from building enclosure inner surface.IfIgnore interior wall influence, only considers the Radiant exothermicity of peripheral structure (door, window, wall), the average temperature of the inner surface of peripheral structureDegree is mean radiant temperature ts, can be calculate by the following formula to obtain:
In formula, αiFor heat exchange coefficient of interior surface, αoFor the outer surface coefficient of heat transfer, k is peripheral structure heat transfer coefficient, toForOutside air temperature, ρ are solar radiation absorbility factor, and I is the solar irradiance on horizontally or vertically surface.And solar radiation is strongDegree depends on the earth to the relative position (solar elevation and path) of the sun and atmospheric transparency and peripheral protective surface direction(horizontal, east, south, west, north) etc..
According to a particular embodiment of the invention, PMV control interval is corrected according to the active state of user, comprising: the PMVSection is defaulted as [- 0.5 ,+0.5]；When user sleep soundly, the section PMV is defaulted as [0 ,+1].When air conditioner refrigerating, the section PMV is[0 ,+0.5], when air-conditioning heating, the section PMV is [- 0.5,0].
According to a particular embodiment of the invention, further includes: the section PMV is corrected according to the adjustment direction of user and is recorded.
Embodiment one
The pmv value control interval of default setting thermal comfort is [- 0.5 ,+0.5], by taking air conditioner refrigerating as an example:
1) work as pmv value > 0.5, show temperature drift, publication cooling control command；
2) when Zhi≤0.5-0.5≤PMV, show proper temperature, do not need publication temperature control instruction；
3) when pmv value < -0.5, show that temperature is relatively low, publication heating control instruction；
4) the air conditioner refrigerating stage, it is [0 ,+0.5] that PMV control interval, which is biased to warm side,；
5) if user's entrance is slept soundly or sound sleep phase, PMV control interval can be adjusted to [0 ,+1]；
If user intervention, by compared with current pmv value and behavior that user adjusts upward or downward adjusts PMV controlSection.
In conclusion the present invention is a kind of based on multifactor room air conditioner comfort level control method, by making indoorsTo the side in hotter direction when cold, PMV target value is set to the side in colder direction when heating, and according to not after sleep qualitySame sleep stage adjusts PMV control interval in due course, inhibits excessive energy consumption within the scope of comfort level, realizes air conditioner loadMitigate and realizes energy conservation.And correct PMV control interval in time after receiving user intervention, realize a kind of comfortable Energy Saving ControlMethod.
