Intensive adjacent air inlet return gas channel in the combined evaporimeter; Make the convection current of turnover air-flow large tracts of land intersection realize heat exchange efficiently through the air gateway that is the diagonal angle distribution; Realize that the sensible heat between the turnover air shifts fast, make the air that gets in the combined evaporimeter and go out obtain precooling and backheat respectively.
Air by inlet channel from top to bottom contact heat spreader with the dehumidifying heat pipe, its temperature progressively reduces, when temperature was lower than the saturated dew point of steam, the moisture of supersaturated concentration will be separated out and air separation in the air.
Become liquid state with the moisture after the air separation by gaseous state, the part water droplet flows to bottom, demist chamber and discharges through discharge outlet, but part can be vaporific being suspended in the air, if this part water smoke is not handled, these moisture are easy to follow in the air return chamber.
For preventing to scurry on the formed water smoke in the demist chamber; Water smoke is set in the demist chamber intercepts net, from the inlet channel air of the return gas channel obstruct net of must flowing through of turning back, airborne water smoke meets the obstruct net of low temperature like this; Can form the extension pearl and gutter down, effectively stop water smoke to be taken out of with air.
Air after the cooling demist is turned back from the bottom to top from the demist chamber and is got into each return gas channel; Because the temperature of combined evaporimeter raises from the bottom to top gradually; Air can absorb when up flowing from return gas channel below that the heat of air progressively recovers its temperature in the inlet channel through conduit wall; Can be more lower slightly because of its temperature of the heat exchange temperature difference than room temperature, like needs air is further cooled off, through the cold medium flux of room temperature control valve control air outlet heat pipe; Can lower the temperature again to air-out as required, be adjustable to suitable leaving air temp.Through control throttle valve control cold medium flux or evaporating pressure; Controlled refrigeration condensation point temperature is regulated moisture removal; Through the cold medium flux ratio between control room temperature control valve and the by-passing valve, can control leaving air temp flexibly, the leaving air temp of air-conditioner and humidity can independently be controlled.
Because the flow path of refrigerant is to arrive the air outlet heat pipe again through the dehumidifying heat pipe earlier; Refrigerant will consume certain cold in the dehumidifying stage; So the temperature of refrigerant when arriving the air outlet heat pipe can be than before not low, the temperature of air outlet heat pipe can not be lower than the temperature of dehumidifying heat pipe; The air themperature that forms in the demist chamber is minimum relatively in All Ranges; Through the air that return gas channel flows out to the end, its steam full concentration can not occur and just not have again dewfall to produce yet, and or else has the possibility that water smoke or water droplet are taken out of.
When room air is flowed through inlet channel near dehumidifying during heat pipe; Absorbed the cold of most of air of turning back away after the cooling in the return gas channel; Fully precooling of air before the contact dehumidifying heat pipe; Behind the dehumidifying heat pipe peripheral region of flowing through, lack much than conventional air conditioner with the temperature difference of peripheral heat pipe and fin surface, the dew point that obtains because of air more hangs down the dewfall condition is improved greatly; Under the situation of equal evaporating temperature and equal air quantity excessively, the present invention significantly improves than conventional air conditioner dehumidifying usefulness.
The leaving air temp of conventional air conditioner is generally at 8-14 ℃; And summer its leaving air temp all 12 ℃ or more than; The moisture removal of conventional air conditioner and its leaving air temp have direct relation; Air is the minimum zone of temperature in its whole cooling procedure in the zone of leaving evaporator fin moment, and this regional steam-laden concentration has determined the water content of dehumidifying back air.The present invention is then different, because its air outlet is not air minimum zone of temperature in whole cooling procedure, but is positioned at the demist chamber, and the air moisture content after the dehumidifying depends on the saturated concentration of steam in the demist chamber.
Conventional air conditioner is very short in the time and the path of the heat exchange of air and evaporimeter; Evaporator surface temperature air themperature cooled with it differs very big; In that its temperature difference is generally about 10 ℃ during EAT more than 30 ℃, and high more its temperature difference of EAT is big more.The present invention will grow much the heat exchange path of air and fin and time, and its heat exchange temperature difference can be about 2 ℃, and EAT is high more also influenced hardly.That is to say; Both are when identical evaporator temperature, and the dew point that the present invention removes wet zone will hang down about 8 ℃, calculate steam-laden concentration separately according to both dew point difference; Air moisture content during with 12 ℃ of air-out air is an example, and conventional air conditioner can only reach 10g/m
3, and the present invention can reach 6.4g/m
3, moisture removal improves 36%.
It should be noted that; The present invention turns down evaporating temperature through the Energy Efficiency Ratio of sacrificing refrigeration machine to exchange low dew point for; But on existing evaporating temperature basis, improve the dew point that heat exchanger effectiveness reduces air, add in demist the chamber in water smoke intercept net can be to the airborne most dewdrop obstruct of flowing through, and the water smoke that suspends between dew that adheres on the fin of conventional air conditioner and sheet; Be easy to taken out of, be commonly called as " spraying white cigarette " by blower fan.The present invention and conventional air conditioner can be described the disposal ability of moisture: the former " grab manyly, race lack ", and latter's " grab fewly, race many ".
The present invention's dehumidifying effect in hot and humid environment obviously improves; Being mainly reflected in heat exchange efficiently makes the air of flowing through obtain more to hang down dew point and separate out more juicy; The connecting inner structure is kept the moisture of separating out here more; Comprehensive above under the situation of equal evaporating temperature, the present invention can reduce half the approximately than its air-out water content of existing air-conditioner, improve effect on moisture extraction greatly.
The dehumidification mode that the tradition air-conditioning is taked when room temperature is low is to realize dehumidifying through the intermittently starting refrigeration compressor, and this mode can cause when compressor operation, making the people to feel cold, when compressor stops, making us producing unhappy sensation.The present invention dehumidifies continuously under the situation that can reduce room temperature under the above-mentioned situation hardly and produces dry and comfortable air, lets the people feel as snug as a bug in a rug.
As below 20 ℃, the clammy season of relative air humidity more than 95%, can reduce even close the room temperature control valve; Air through dehumidifying heat pipe dehumidifying and backheat after no longer cooling directly blow out; Air-out relative humidity can be about 35%, and through the heat exchange of return air channel and inlet channel air, last leaving air temp can reach 18 ℃; The air of this temperature gets into to be estimated only to reduce after the indoor circulation in 1 ℃ of the room temperature, but can significantly reduce air humidity.And conventional air conditioner is under said temperature, and leaving air temp can be below 12 ℃, in order to satisfy dehumidifying needs, make become more cold and increase power consumption of the indoor meeting of original low temperature.
" dehumidification mode " that conventional air conditioner is provided with can be provided under the lower situation of temperature and adopt, and when " dehumidification mode ", the refrigeration compressor intermittent running constantly reduces to prevent room temperature, also avoids evaporimeter frosting to occur.Simultaneously; The speed of service of breeze fan can reduce when " dehumidification mode "; Very slow sometimes; Be in order to prevent the too fast evaporator surface that flows through of air, causing steam to have little time dewfall because of heat exchange is insufficient influences effect on moisture extraction, prevents that also the excessive handle of wind-force from blowing toward indoor attached to the water droplet of evaporator surface.But problem is: the excessive cycle of compressor start-stop; Can cause the variation wave amplitude of indoor temperature and humidity excessive, let the people that sense of discomfort is arranged, if the cycle of compressor start-stop is too short; Because of frequent starting can reduce its life-span; And the increase power consumption, and breeze fan slows down and also can influence the flowability of room air, can let the people feel unhappy.
The present invention has improved above-mentioned condition fully, and when low temperature adopted " dehumidification mode ", the room temperature control valve got the flow-control of refrigerant seldom even cuts out; The cold that compressor operating produced, the zone that almost concentrates on the dehumidifying heat pipe of combined evaporimeter below discharges, because the cold that the air of the combined evaporimeter of flowing through is finally taken away is seldom; The actual consumption cold mainly be the latent heat of water vapor condensation phase transformation, and generally speaking the latent heat energy consumption account for the refrigeration total amount ratio little, even if the compressor break-off; The inner stored cold of combined evaporimeter can be kept the long period and consume, thus the compressor operating resting period can prolong greatly,, consumption cold slow situation fast in the refrigeration compressor operating time scale of ordering reduces; During compressor quit work, breeze fan can be preserved normal air output always, as long as the temperature of combined evaporimeter below is still low; Its dehumidification function just can be kept always; As between evaporimeter and compressor, being connected in series constant pressure valve, perhaps adopt frequency-changeable compressor or digital scroll compressor, constant evaporating pressure and minimizing cold medium flux when simple dehumidifying; The compressor underload is turned round continuously; Can produce dry air continuously and less reduce room temperature, continue to keep suitable humidity, temperature and the flowability of room air, and very energy-conservation.
The present invention can pass through commutative about ninety percent the sensible heat of combined evaporimeter when low temperature dehumidification; Can abdicate the wind-warm syndrome degree near EAT; Being used for when promptly dehumidifying that air cooling-down partly consumes energy is about 10% of conventional air conditioner, so compare with conventional air conditioner, the load of compressor will be lacked much when dehumidifying; No matter be continuous operation or discontinuous operation, its energy-saving effect is all very obvious.
The present invention controls the refrigerating capacity of dehumidifying heat pipe through control refrigeration compressor or choke valve, and the water content of scalable air-out strengthens or reduce the refrigerating capacity of air outlet heat pipe, the cooling extent of scalable air-out through the regulating valve flow that regulates the room temperature.
If the dehumidifying claimed range allows, but the evaporating temperature relative fixed of the inner refrigerant of dehumidifying heat pipe, and choke valve can adopt capillary.
The heat-conducting medium that circulates in dehumidifying heat pipe and the air outlet heat pipe can be the circularly cooling working medium that refrigeration compressor directly provides; Also can be the circulating frozen liquid of processing by refrigeration system; The effect that is produced is similar; Circulate respectively and between many covers combined evaporimeter through multitube road branch cold water, can be applicable to central air conditioning project.
The air outlet heat pipe of combined evaporimeter can belong to same heat exchange closed circuit with the dehumidifying heat pipe; Also can three-way valve be set respectively and switch the connection peripheral conduits, can make air outlet heat pipe and dehumidifying heat pipe independently belong to different heat exchange closed circuits separately respectively at air outlet heat pipe gateway end.Need to carry warm braw and when dehumidifying simultaneously, the air outlet heat pipe can cooperate with other heat exchange closed circuit, realizes the function that the air after dehumidifying is heated when indoor.
