Further, in the time that described indoor apparatus of air conditioner also comprises humidity sensor, described dehumidifying sideMethod comprises:
Step 601, obtain the indoor environment humidity that described humidity sensor measurement obtains.
Step 602, according to described indoor environment temperature, described indoor environment humidity and second defaultRule, determines the 4th target evaporating temperature and the 5th target evaporating temperature, the described second default ruleComprise the corresponding relation of indoor environment temperature, indoor environment humidity and the 6th target evaporating temperature.
If the evaporating temperature of the described evaporimeter of step 603 is more than or equal to described the 4th target evaporationTemperature, regulates the aperture of at least one described throttling arrangement in open mode.
If the evaporating temperature of the described evaporimeter of step 604 is less than or equal to described the 5th target evaporationTemperature, regulates the aperture of at least one described throttling arrangement in closed condition.
Wherein, described the 4th target evaporating temperature and described the 5th target evaporating temperature are for according to instituteState that the 6th target evaporating temperature and the second predefined threshold value obtain, described the 4th target steamsSend out temperature and be greater than described the 5th target evaporating temperature.
Below, with reference to the structural representation of the indoor apparatus of air conditioner shown in figure 7 to indoor apparatus of air conditionerDehumidification process is elaborated.
Concrete, under dehumidification mode, the first temperature sensor 21 and Temperature Humidity Sensor 25The evaporating temperature of the evaporimeter 13 being recorded and indoor environment temperature and indoor environment humidity are sent outGive controller 23, controller 23 is according to the indoor environment temperature, the indoor environment humidity that getWith the corresponding relation of the 6th target evaporating temperature, determine described the 4th target evaporating temperature and the 5thTarget evaporating temperature.
Example, indoor environment temperature, indoor environment humidity and the 6th target evaporating temperature rightAnswer the relation table can reference table 2, in table 2, the first row represents indoor environment humidity, and first row representsIndoor environment temperature, remainder is corresponding under different indoor environment temperatures and indoor environment humidityThe size of the 6th target evaporating temperature. If a certain moment, the chamber that Temperature Humidity Sensor 25 recordsInterior environment temperature is 28 DEG C, and indoor environment humidity is 70%, by known the 6th target evaporation of tabling look-up6 DEG C of temperature. If the second predefined threshold value is 1 DEG C, the 4th target evaporating temperature is 7 DEG C, theFive target evaporating temperatures are 5 DEG C. Wherein, the second predefined threshold value can be with first predefinedThreshold value is identical, also can be different.
Table 2
Reference table 2 and Fig. 4, if the current evaporating temperature of evaporimeter 13 is 11 DEG C, controller 23By more known, the evaporating temperature of evaporimeter 13 is greater than the 4th target evaporating temperature (7 DEG C),Now, controller 23 electromagnetic valve for adjustings 32 are closed, the now effective heat exchange area of evaporimeter 13Reduce, heat exchange amount also reduces thereupon, thereby the reduction of the evaporating temperature of evaporimeter 13, in air conditioning chamberThe dehumidifying effect of machine will increase. If magnetic valve 32 cut out after a period of time, example, as fiveAfter minute, the evaporating temperature of evaporimeter 13 is still greater than the 4th target evaporating temperature, controller23 control magnetic valve 31 again closes, and makes the evaporating temperature of evaporimeter 13 continue to reduce. If evaporationThe evaporating temperature of device 13 is 6 DEG C, and this evaporating temperature had both been less than the 4th target evaporating temperature, large againIn the 5th target evaporating temperature, this Time Controller 23 does not regulate the aperture of throttling arrangement.If the current evaporating temperature of evaporimeter 13 is 3 DEG C, controller 23 passes through more known, evaporimeter13 evaporating temperature is less than the 5th target evaporating temperature (5 DEG C), and now, controller 23 is controlledMagnetic valve 31 is opened, and now the effective heat exchange area of evaporimeter 13 increases, and heat exchange amount also thereuponIncrease, thereby the evaporating temperature of evaporimeter 13 improves. If magnetic valve 31 was opened after a period of time,The evaporating temperature of evaporimeter 13 is still less than the 5th target evaporating temperature, and controller 23 is controlled electricityMagnet valve 32 is opened, and continues to increase the effective heat exchange area of evaporimeter 13, makes the steaming of evaporimeter 13Sending out temperature continues to increase.
It should be noted that, the throttling arrangement arranging on the isocon below being positioned at is closes shapeState or aperture hour, because essentially no cold-producing medium in isocon flows through, now isoconTemperature can be higher, is positioned at the water droplet that liquefies and produce on the isocon that has cold-producing medium to flow through of topWhile dropping onto on the isocon that below temperature is higher, can again evaporate, this can reduce removing of indoor setWet ability. So, preferred, can, according to the difference of the position of isocon in evaporimeter, pressRegulate successively the aperture of the throttling arrangement on isocon according to order from bottom to top. Certainly, not according toAccording to this order or it is also feasible regulating the mode of multiple throttling arrangements simultaneously.
The dehumanization method of the indoor apparatus of air conditioner that the embodiment of the present invention provides, passes through indoor environment temperatureDetermine target evaporating temperature, then by target evaporating temperature determine first object evaporating temperature andThe second target evaporating temperature, and by the evaporating temperature of evaporimeter and first object evaporating temperature andTwo target evaporating temperatures compare. When the evaporating temperature of evaporimeter is evaporated temperature higher than first objectWhile spending, the dehumidifying effect that indoor set is described excessively a little less than, now, regulate at least one in opening shapeThe aperture of the throttling arrangement of state, to reduce the effective heat exchange area of evaporimeter, effective heat exchange areaAfter reducing, the evaporating temperature of evaporimeter will reduce, and then can improve the dehumidifying energy of indoor setPower. Dehumanization method of the present invention, by detecting evaporating temperature and the indoor environment of evaporimeterTemperature, regulates the aperture of the throttling arrangement on evaporimeter isocon in real time, makes indoor apparatus of air conditionerCan maintain good effect on moisture extraction. Meanwhile, in the suitable situation of indoor environment humidity, peopleSendible temperature can decline to some extent, in design temperature, what just can not arrange is too low, because ofAnd can in reducing air-out humidity, improve leaving air temp, can make weak groups of people feel moreAdd comfortablely, can reduce again indoor/outdoor temperature-difference simultaneously, reduce the energy consumption of air-conditioning. With prior art phaseRatio, the dehumanization method of the indoor apparatus of air conditioner that the embodiment of the present invention provides, has solved existing air-conditioning and has existedThe poor problem of dehumidifying effect under partial load condition.
Further, after dehumidifying effect strengthens, indoor humidity reduces, people's sendible temperature meetingDecrease, now conventionally can improve the design temperature of air-conditioning, like this, can reduce indoor and outdoorThe temperature difference, reduces air conditioning energy consumption, and after design temperature raising, leaving air temp also can correspondingly improve,For weak crowd, can feel more comfortable. Steam lower than the second target and work as evaporating temperatureWhile sending out temperature, illustrate that the evaporating temperature of indoor set is too low, now, regulate at least one in closingClose the aperture of the throttling arrangement of state, can increase the effective heat exchange area of evaporimeter, improve and steamSend out temperature, improve the comfort level that air-conditioning uses. In addition, add humidity sensor measurement indoorAmbient humidity, and the 4th order of jointly determining according to indoor environment temperature and indoor environment humidityWhen mark evaporating temperature and the 5th target evaporating temperature regulate the aperture of throttling arrangement, to jointThe control accuracy of stream device is higher.
