Task of the present invention has being solved for the method for the equipment of air humidification and a kind of equipment for air humidification with the feature of claim 11 for controlling of the feature of claim 1 by a kind of.
Advantageous scheme of the present invention and expansion scheme provide in the dependent claims.
According to of the present invention, for controlling for air humidification equipment, (this equipment comprises can by heating element heats, for the boiler of liquid to be evaporated, this boiler has cap relief valve, can output to space from boiler by this cap relief valve steam, this boiler to be connected with the first stalk road with the region be arranged in during liquid filling boiler below liquid level and to be provided with the device for determining liquid level in the boiler being usually in operation) method when comprising the steps: that step a) is at least filled to default upper liquid level in the boiler when liquid, close cap relief valve.Then in step b) in, connect heating element heater and heating liquid, produce steam pressure thus, liquid is pressed into stalk road from boiler by this steam pressure.In step c) in, once lower than the lower liquid level preset in boiler, then turn off heating element heater.According to steps d), determine duration between the turning on and off of heating element heater and heating element heater connection and close the duration of having no progeny between the moment again arriving default upper liquid level at heating element heater.Subsequently in step e) in, by the duration between the turning on and off of heating element heater and the base load determining this equipment in the connection of heating element heater and the ratio of duration that closes between the moment again arriving default upper liquid level of having no progeny at heating element heater.
Base load this heat loss corresponding to this equipment in other words for compensate this equipment heat loss needed for thermic load.By be switched in alternation and turn off heating element heater and heat time make liquid from boiler enter stalk road and cool time make liquid be back to boiler from stalk road, the liquid in boiler roughly can remain on boiling point, and does not produce high overvoltage in the boiler.There is provided a kind of open system by stalk road, therefore this system substantially works without pressure and therefore only needs the operation enabled condition of simplification.By determining that (on the one hand) duration between the turning on and off of heating element heater and (on the other hand) are closed the duration of having no progeny between the moment again arriving default upper liquid level in the connection of heating element heater with at heating element heater and determined that ratio can be determined the base load of this equipment in a straightforward manner and uses it for efficient and energy-conservation control this equipment subsequently.
Advantageously, water is used as liquid.
One of the present invention particularly preferred embodiment regulation, if continuous standby mode, so repeatedly repeats step b in standby mode) and c), preferred steps b) to e).Therefore, in the standby mode of cap relief valve closedown, minimum pressure is formed periodically in the boiler.Overvoltage in boiler is determined indirectly by the liquid level in boiler.Carry out when cap relief valve is closed heating until because the pressure in boiler raises by so many liquid press-in stalk, so that lower than the lower liquid level in boiler.So then boiler cools again based on heat loss and liquid can be back to boiler again from stalk.After arriving initial upper liquid level, heating element heater again activates and reheats liquid.This equipment heat loss in standby mode being used for air humidification can be determined in the following manner by evenly heat power, namely determines that the on-time of heating element heater accounts for the percentage of the duration (namely connecting the duration between the moment for two) of a circulation.This percentage due to the on-time corresponds to the base load of this equipment, therefore boiler can be remained on boiling temperature.

Fig. 1 is the schematic diagram of a kind of embodiment of equipment for air humidification.
Detailed description of the invention
Fig. 1 illustrates the schematic diagram of the equipment 10 for air humidification.This equipment 10 comprises boiler 12, is equipped with and waits be in operation liquid 24, the preferred water of evaporating in this boiler.In boiler 12, be provided with heating element heater 14, can heat by this heating element heater and especially evaporating liquid 24.Boiler 12 especially at an upper portion thereof in region, such as in cap surface, have cap relief valve 16, can be outputted to space from boiler 12 by this cap relief valve steam, as in the space of air-conditioning cabinet or environmental simulation cabinet.
Equipment 10 also comprises the first stalk road 20, and it can be configured to rise liquid hard tube or rise liquid flexible pipe.The bottom on stalk road 20 passes into the region under the liquid level being arranged in liquid 24 when conventional operation of boiler 12.
In boiler 12, be provided with the device for determining liquid level, this device can be configured to switch 18.In addition, boiler 12 comprises feed flow portion 26, and this feed flow portion can block by liquid feed valve 28 in the ideal case.In one embodiment, flow regulator 29 can be set in feed flow portion 26.Replace flow regulator 29 also can arrange flow restrictor in feed flow portion 26, it is set to fixed value.
In a preferred embodiment, boiler 12 can comprise safety valve 22, when can produce too high overvoltage by this safety valve in boiler 12, pressure is discharged boiler 12.
Equipment 10 can comprise drain vessel 30.Especially the condensate liquid gathered in space is collected in drain vessel 30 by condensate liquid backflow portion 38.In addition, drain vessel 30 can have the second stalk road 32, and advantageously this second stalk road is configured to rise liquid hard tube or rise liquid flexible pipe.Second stalk road 32 to pass on its lower end in drain vessel 30 and thereon end is connected with the upper end on the first stalk road 20.
Can be provided with the device for determining liquid level in drain vessel 30, this device is especially configured to switch 36.In addition, drain vessel 30 can comprise the draining pump 34 for waste water to be pumped into delivery port from drain vessel 30.
Equipment 10 also can comprise temperature sensor 42, and this temperature sensor is testing environment temperature especially.Equipment 10 also can have unshowned, for determining the temperature sensor of liquid 24 temperature in boiler 12.
Equipment 10 comprises adjusting device 40.This adjusting device 40 especially turns on and off heating element heater 14, opens and closes cap relief valve 16, opens liquid feed valve 28, then may also adjust flux adjuster 29 as existed, and then preferably turns on and off draining pump 34 as existed.In addition as there is then adjusting device 40 also adjustable safety valve 22.Adjusting device 40 when consider especially detected by device, the i.e. switch 18 and possible temperature sensor 42 for determining liquid 24 liquid level in boiler 12 and the information transmitted implement described control.In a kind of expansion scheme, by for determining that the information that the device of the liquid level in drain vessel 30 detects also can be included in described adjusting device.
The base load of equipment 10 can be determined as follows: when liquid 24 is at least filled to default upper liquid level in boiler 12, cap relief valve 16 is closed.Heating element heater 14 is connected, so that heating liquid 24, produces steam pressure thus, and a part of liquid 24 is pressed into the first stalk road 20 from boiler 12 by this steam pressure.Once lower than the lower liquid level preset in boiler 12, then heating element heater 14 turns off.When for determining that the device of the liquid level in boiler 12 is configured to switch 18, upper liquid level is relevant to the first switching point of switch 18 and the lower switching point of lower liquid level and switch 18 relevant.Especially under arriving, send signal to turn off heating element heater 14 by switch 18 to adjusting device 40 when liquid level, and send signal to connect heating element heater by switch 18 to adjusting device 40 during liquid level on arriving.Such as determine duration between the turning on and off of heating element heater 14 by adjusting device 40 and in the connection of heating element heater 14 with close to have no progeny at heating element heater 14 and again arrive default upper liquid level and duration especially between moment of reclosing in several cycles of heating element heater 14.By the duration between the turning on and off of heating element heater 14 and in the connection of heating element heater 14 with close to have no progeny at heating element heater 14 and again arrive default upper liquid level and the ratio of duration especially between moment of reclosing of heating element heater 14 can determine base load, the i.e. heat loss of equipment 10.Preferably determine base load by multiple circulation, to improve the accuracy of determined base load.Especially preferably during standby mode, base load is determined when equipment 10 is connected first.
If liquid level exceedes liquid level when connecting first, then advise that the base load value determined in the cycle is not considered or just starts to be considered from the upper liquid level of arrival, otherwise this value can cause determined base load inaccurate.In addition for this reason can in the high heating period repeatedly, such as with stipulated number repeatedly arrive under liquid level time or be about to arrive on liquid level until arrive on liquid level time open cap relief valve 16, to make boiler 12 be vented.Just continue to close cap relief valve 16 to determine base load after the circulation of stipulated number.Due to liquid 24 by pressure raise be pressed into the first stalk road 20 and therefore especially switch 18 be in lower liquid level, therefore to let off steam by opening cap relief valve 16/air mixture and liquid 24 flows back to boiler 12 from stalk road 20.When arriving the upper liquid level in boiler 12, cap relief valve 16 is closed again.
Alternatively or additionally, temperature in boiler 12 can also be determined and when almost or completely arriving boiling temperature, cap relief valve 16 is just closed to determine base load.
Standby mode is especially connected when not existing and providing the request signal of steam to space, and therefore equipment 10 runs like this, makes to carry steam at any time in space when there is new request signal.In standby mode, advantageously equipment 10 is controlled as and makes to remain on boiling point to liquid 24 substantial constant in boiler 12.In boiler 12, do not produce overvoltage thus or only produce little overvoltage, but equipment 10 is ready, so that response request signal and by means of only by the thermic load of heating element heater 14 improve less value in heat boiler 12, just can produce steam immediately, then this steam can be outputted in space by cap relief valve 16 in operational mode.
In standby mode, liquid 24 remains essentially in boiling point in the following manner.Cap relief valve 16 is closed.Heating element heater 14 is connected and liquid 24 is heated, and produces steam pressure thus, and liquid 24 is pressed into the first stalk road 20 from boiler 12 by this steam pressure.Once lower than the lower liquid level preset in boiler 12, then heating element heater 14 turns off again.By being pressed into by liquid in the first stalk road 20, boiler 12 substantially keeps with no pressure and produce steam hardly in boiler 12, but liquid 24 can remain on boiling point substantially.Liquid 24 in boiler 12 is cooled again by heat loss, so that liquid 24 can be back to boiler 12 from stalk road 20 again, and the liquid level thus in boiler 12 raises again.Once again arrive upper liquid level, heating element heater 14 can be connected again.
In standby mode, duration between the turning on and off of heating element heater 14 can be determined and in the connection of heating element heater 14 with close to have no progeny at heating element heater 14 and again arrive default upper liquid level, duration namely especially between heating element heater 14 moment that can reclose, and subsequently can by the duration between the turning on and off of heating element heater 14 and in the connection of heating element heater 14 with close to have no progeny at heating element heater 14 and again arrive the ratio determination base load of default upper liquid level, duration namely especially between heating element heater 14 moment that can reclose.This base load is continuously applied to heating element heater 14 and is adjusted if desired again in operational mode, so that the heat loss in corresponding compensation boiler 12.
In a kind of expansion scheme of this control method, determine the environment temperature of equipment 10 by temperature sensor 42 and this environment temperature such as all associates with corresponding base load when determining base load at every turn, as being jointly stored.When environment temperature changes along with operation, also need to change base load to compensate heat loss.Such as once determine variation of ambient temperature, then can regulate base load to be applied again to compensate heat loss according to the environment temperature newly determined.
When determining by switch 18 to continue the lower liquid level lower than presetting, by feed flow portion 26 liquid make-up.Open liquid feed valve 28 and the corresponding adjust flux adjuster 29 of possibility for this reason.
Advantageously, determine the diameter on the first stalk road 20 and the size of volume like this, the volume be forced out from boiler 12 in standby mode can be received by the first stalk road 20, and liquid can not overflow the upper end on the first stalk road 20, otherwise this can cause the loss of the liquid 24 in boiler 12.Further advantageously, the height on stalk road 20 and the size of diameter can be determined like this, make it possible to the static pressure produced for the steam formed in boiler 12 to be pressed through cap relief valve 16 when cap relief valve 16 is opened.In one embodiment, boiler 12 can have the diameter of about 15cm and the height of about 20cm.Boiler 12 can be filled until only about half of by liquid 24.Upper liquid level in boiler 12 and the difference between lower liquid level are about 1mm.The diameter on the first stalk road 20 is about 1.5cm.The height on the first stalk road 20 is such as about 1m.
When equipment 10 runs, the impurity of the liquid 24 in boiler 12 increases, because only liquid vapors is discharged by cap relief valve 16, and impurity remains in boiler 12.In order to reduce impurity, advantageously rinse mode is set.In rinse mode, cap relief valve 16 is closed and preferably heating element heater 14 turns off.Liquid feed valve 28 is opened and liquid 24 enters in boiler 12 via feed flow portion 26.Because the volume of air in boiler 12 can only Limited compression, therefore when liquid feeds in boiler 12 liquid 24 be extruded by the first stalk road 20 and in the corresponding infeed boiler 12 of liquid time flow in drain vessel 30 especially by the second stalk road 32.In this way, the liquid 24 being rich in impurity at least partially in boiler 12 to substitute by fresh, containing less impurity liquid 24 and therefore liquid 24 is diluted and impurity is flushed away.This rinse mode can certain hour interval or implement when needed.
At run duration, rinse as also carried out when each standby mode starts or dilute.When at run duration, especially in several cycles or largely supply liquid 24 time, the volume be forced out in the heating period is so big, so that by the first stalk road 20 liquid is discharged boiler and realize in this way rinsing.
When gathered in drain vessel 30 a large amount of liquid 24, especially more than preset liquid level (this detects by the switch 36 be arranged in drain vessel 30) time, by draining pump 34, waste water can be discharged drain vessel 30.
In the operational mode set at response request signal, cap relief valve 16 is opened.Heating element heater 14 is not only loaded by base load, and is additionally loaded by the thermic load corresponding to request signal.Request signal determines should there is which kind of humidity in space.Steam is asked, until reach desired humidity by the humidity in respective sensor detection space.When producing desired humidity in space, just no longer send request signal.So equipment 10 can be transformed in standby mode again.
