Description
One, technical field
The present invention relates to a kind of method of operation of air-conditioner, relate in particular to a kind of temperature setting and dehumidify operating mode of air-conditioner.
Two, background technology
In general, air-conditioner is used for temperature higher summer, the hot-air in the suction chamber and carry out heat exchange make be discharged into again after its cooling indoor, thereby indoor air is adjusted to suitable temperature.Air-conditioner is mainly formed cooling cycle system and is produced cold air by compressor, condenser, evaporimeter and expansion valve, and the cold air that is produced is discharged by ventilating fan.The cold media gas of low-temp low-pressure becomes high temperature and high pressure gas by compressor compresses, the cold media gas of HTHP is a highly pressurised liquid through condenser condenses, makes its distinguished state that becomes low-temp low-pressure and continuation become the cold media gas of low-temp low-pressure by evaporimeter by expansion valve then; A large amount of heat absorptions and air is cooled off from surrounding air simultaneously, it is indoor that cooled air is discharged into by ventilating fan, thereby reduce indoor temperature.In above-mentioned air-conditioner, when evaporator surface temperature is lower than the dew point of indoor water vapour, will condense into condensed water with the contacted water vapour of evaporimeter, the air humidity that gives off is reduced.
As shown in Figure 1, the evaporimeter of needle tube type is to be made of refrigerant pipe and the cooling pin that is fixed on the refrigerant pipe.Because the refrigerant pipe forms sandwich construction on air-flow direction, so the air of inflow evaporator has the tangible temperature difference with the air that flows out evaporimeter, in passing through the process of evaporimeter, airborne water vapour is lower than the variation of dew-point temperature occurrence temperature and states of matter because of its temperature simultaneously.
As shown in Figure 2, when air passed through evaporimeter, the temperature of air constantly descended, and the states of matter of airborne water vapour is put b mutually by putting a arrival mutually; From the thermodynamic function line as can be seen, this interval is the sensible heat constant interval, and the humidity of air does not change, but the temperature of air has dropped to B ' by A '.The air themperature continuation descends and passes through to export when flowing out evaporimeter, and the states of matter of airborne water vapour is put c mutually by putting b arrival mutually, and this interval is the latent heat constant interval, and the humidity of air drops to C by A, and temperature goes out by B ' to drop to C '.In other words, by in the process of evaporimeter, the total amount of heat that is lost (from a point of thermodynamic function line to the c point) how much latent heat is arranged, corresponding water vapour condensation is just arranged, thereby play exsiccation at indoor water vapour.
When using air-conditioner, usually indoor temperature is set in certain limit, the regulator control system that refrigerating capacity will be arranged for this reason, so that auto-control refrigerating capacity along with the variation of cooling load, thereby indoor temperature is maintained in the setting range, and this refrigerating capacity regulator control system is with the running of the circulating fan interlock of compressor and indoor set.When indoor temperature was lower than setting range, compressor and circulating fan shut down; When indoor temperature goes back up to above setting range, compressor and circulating fan will restart operation.When utilizing this mode to regulate the room temperature, can suitably adjust the operation of combination compressor and circulating fan and obtain multiple refrigeration mode, as fast-refrigerating and dehumidifying isotype.
Above-mentioned dehumidification operating mode is many at the humidity height and the lower intermittent drizzles in the rainy season of temperature adopt season, for the least possible cooling, the refrigerant circulation of dehumidification air conditioner reduced and keep the circulating fan running, in this dehumidification mode, if compressor constantly turns round, then the temperature of evaporimeter will be lower than the dew point of water vapour and cause unnecessary refrigeration, so the running of compressor should be step; Under the state that compressor shuts down, the condensed water that condenses on the evaporimeter will be discharged into indoor with air, will cause the humidity of room air higher like this.Promptly as shown in the figure, in the interval that compressor shuts down, total refrigerating capacity will reduce greatly, so that rely on absorb latent heat and can not make the water vapour condensation, so that damp atmosphere certainly will be discharged to is indoor.For preventing the generation of this situation, circulating fan is shut down the regular hour; But, if stop the circulating fan running for a long time, have when then restarting compressor the cooling load misjudgment can take place, thus must restart after circulating fan stall a period of time, and at this moment the problem to indoor discharging highly humid air can appear.
Three, summary of the invention
Purpose of the present invention promptly is to provide a kind of method of operation of air-conditioner, sustainable when making it that indoor temperature maintained certain limit room air is dehumidified.
The objective of the invention is to realize by following technical scheme.
A kind of temperature setting and dehumidify operating mode of air-conditioner is characterized in that, it comprises following each stage: the refrigeration incipient stage of carrying out along with the running of compressor and circulating fan; Because refrigeration judges whether indoor temperature reaches the indoor temperature judgement stage of indoor temperature setting value; Shut down the stage when compressor and circulating fan shut down when described indoor temperature reaches the indoor temperature setting value; Can judge run down time was judged the stage when whether compressor and circulating fan run down time had crossed the setting value of compressor and circulating fan run down time; When the while run down time had been crossed compressor and circulating fan run down time setting value, compressor started running once more, and circulating fan is also restarted the stage at the compressor of halted state; Judge compressor when starting once more to the circulating fan dwell time, whether crossed compressor and judged the stage to the circulating fan dwell time of circulating fan dwell time setting value when starting once more; When the circulating fan run down time had been crossed setting-up time, circulating fan started the circulating fan of running once more and restarts the stage; Because compressor and circulating fan start once more, refrigeration is once more under the initial state, judge whether to have surpassed the indoor temperature setting value, when not surpassing the indoor temperature setting value, the indoor temperature that turns back to the above-mentioned stage that shuts down is simultaneously again judged the stage once more.
When air-conditioner is moved in a manner described, can make indoor temperature remain on certain limit and room air is continued to dehumidify,, also can make the indoor comfortable state of keeping even in the intermittent drizzles in the rainy season season of low temperature and high relative humidity.
Be described in further detail below in conjunction with the technical characterictic of specific embodiment the temperature setting and dehumidify operating mode of air-conditioner of the present invention.

Five, the specific embodiment
As shown in Figure 4, the temperature setting and dehumidify operating mode of air-conditioner of the present invention mainly comprise the refrigeration incipient stage, simultaneously shut down the stage, the stage restarted by compressor and circulating fan is restarted the stage.
The refrigeration incipient stage: start compressor and circulating fan and begin refrigeration (S10), judge whether indoor temperature Thon has reduced design temperature Thoff (S20).
Shut down the stage simultaneously: when indoor temperature Thon had dropped to design temperature Thoff, compressor and circulating fan shut down (S30) simultaneously, judged whether compressor and circulating fan while run down time tdelay reaches setting value t1 (S40).
Compressor is restarted the stage: when compressor and circulating fan when run down time tdelay reaches setting value t1 simultaneously, compressor starts running again, and circulating fan continues to shut down (S50), judges that circulating fan continues run down time tfen and whether reached setting value t2 (S60).
Circulating fan restarts the stage: when circulating fan continuation run down time tfen reached setting value t2, circulating fan restarted (S70) and restarts refrigeration, judges whether indoor temperature Thon drops to design temperature Thoff (S80); Drop to setting value Thoff as indoor temperature Thon, then be back to simultaneously and shut down the stage.
In the above-mentioned stage that shuts down simultaneously, compressor and circulating fan be run down time setting value t1 simultaneously, is meant to keep the inner concora crush of compressor and reduce the indoor needed time of cooling load error in judgement to greatest extent; Restart in the stage at compressor, circulating fan continues run down time setting value t2, hydraulic pressure does not take place when being meant the compressor individual operation contract phenomenon and can keep the required time of normal kind of refrigeration cycle.
The temperature-fixing dehumidifying running of air-conditioner is as follows:
At first, air-conditioner running makes indoor temperature reach design temperature, this moment compressor and the circulating fan certain hour that shuts down simultaneously.Need in the ordinary course of things to judge indoor cooling load, even compressor quits work, and circulating fan works on; But when temperature-fixing dehumidifying because load is very little, so only need at regular intervals to confirm at interval whether excessive getting final product of load.The purpose that circulating fan shuts down is the increase that causes indoor air humidity for the moisture that condenses on the device that avoids evaporating to indoor discharging.
The time that compressor and circulating fan shut down simultaneously is required time of concora crush and set for reducing the indoor needed time of cooling load error in judgement to greatest extent before and after keeping according to compressor, through behind the setting-up time, compressor promptly starts work once more.In order to prevent that indoor evaporator is in that not have under the abundant state of cooling condensate water to be entered again indoor, so the startup of circulating fan should be later than the startup of compressor.Be that compressor and circulating fan shut down after a period of time simultaneously, start compressor earlier, make low temperature refrigerant inflow evaporator and evaporator temperature is fully reduced, after after a while, restart circulating fan.At this moment, the temperature of evaporimeter fully reduces, and the moisture that condenses on the evaporimeter can cause the rising again of indoor air humidity again to indoor discharging.
When compressor and circulating fan start refrigeration and when making indoor temperature drop to setting value, compressor and circulating fan shut down simultaneously, too reduce to prevent indoor temperature once more; On the contrary, when indoor temperature was higher than setting value, compressor and circulating fan remained in operation and freeze and dehumidifying.
In sum as can be known, in the present invention, the running of compressor and circulating fan is intermittent, and indoor temperature is maintained in certain scope, and compressor and circulating fan turn round successively simultaneously, can continue to dehumidify to room air.
