Become liquid state with the moisture after air separation from gaseous state, part water droplet flows to bottom demist chamber and discharges through discharge outlet, but part can in vaporific suspension in atmosphere, if not to this part water smoke process, these moisture are easy to follow air and return to indoor.
For preventing that the water smoke that formed in demist chamber is altered, in demist chamber, arrange water smoke intercept net, must flow through obstruct net from the turn back air of return gas channel of inlet channel like this, the water smoke in air meets the obstruct net of low temperature, extension pearl can be formed gutter down, effectively stop water smoke to be taken out of with air.
Air after cooling demist is turned back from the bottom to top from demist chamber and is entered each return gas channel, because the temperature of combined evaporimeter raises from the bottom to top gradually, can absorb the heat of air in inlet channel by conduit wall when air up flows below return gas channel makes its temperature progressively recover, because its temperature of the heat exchange temperature difference can be more lower slightly than room temperature, as needs cool further to air, by the cold medium flux of room temperature governor valve control air outlet heat pipe, again can lower the temperature to air-out as required, be adjustable to suitable leaving air temp.By controlling throttle valve control cold medium flux or evaporating pressure, controlled refrigeration coagulates dew-point temperature to regulate moisture removal, by controlling the cold medium flux ratio between room temperature control valve and by-passing valve, can control leaving air temp flexibly, the leaving air temp of air-conditioner and humidity can independently control.
Flow path due to refrigerant first arrives air outlet heat pipe again by dehumidifying heat pipe, how many refrigerants will consume certain cold in the dehumidifying stage, so, the temperature of refrigerant when arriving air outlet heat pipe can not be lower than before, the temperature of air outlet heat pipe is not less than the temperature of dehumidifying heat pipe, the air themperature formed in demist chamber is relatively minimum in all regions, by return gas channel to the last air flowed out, its steam there will not be full concentration that condensation also would not be had again to produce, and or else has the possibility that water smoke or water droplet are taken out of.
When room air flows through inlet channel near dehumidifying heat pipe, absorb the cold of most of air of turning back away after cooling in return gas channel, air fully precooling before contact dehumidifying heat pipe, after flowing through dehumidifying heat pipe peripheral region, a lot of less with the Temperature Difference Ratio conventional air conditioner of periphery heat pipe and fin surface, the lower condensation condition that makes of dew point obtained because of air is improved greatly, when 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 DEG C, and summer its leaving air temp all at 12 DEG C or more, the moisture removal of conventional air conditioner and its leaving air temp have direct relation, air is the region that in its whole cooling procedure, temperature is minimum leaving the region of evaporator fin moment, and the steam-laden concentration in this region determines the water content of the rear air of dehumidifying.The present invention is then different, because its air outlet is not the air region that temperature is minimum in whole cooling procedure, but be positioned at demist chamber, the air moisture content after dehumidifying depends on the saturated concentration of steam in demist chamber.
Conventional air conditioner time of the heat exchange of air and evaporimeter and path very short, the surface temperature of evaporimeter differs very large with its cooled air themperature, more than 30 DEG C, during EAT, its temperature difference is generally at about 10 DEG C, and EAT its temperature difference higher is larger.The present invention makes the heat exchange path of air and fin and time will grow a lot, and its heat exchange temperature difference can at about 2 DEG C, and EAT is high also influenced hardly again.That is, both are when identical evaporator temperature, and the dew point of dehumidification zone of the present invention is low about 8 DEG C, calculates respective steam-laden concentration according to both dew point difference, for air moisture content during air-out air 12 DEG C, 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, evaporating temperature to be turned down exchange low dew point for by being sacrificed the Energy Efficiency Ratio of refrigeration machine by the present invention, but on existing evaporating temperature basis, improve heat exchanger effectiveness to reduce the dew point of air, add water smoke obstruct net in demist chamber to intercept the most dewdrops flowed through in air, and the water smoke suspended between the dew that the fin of conventional air conditioner adheres to and sheet, be easy to be taken out of by blower fan, be commonly called as " spraying white cigarette ".The present invention and conventional air conditioner to the disposal ability of moisture can describe for: the former " grabs many, lacking of race ", and the latter's " grab few, race many ".
The present invention's dehumidifying effect in hot and humid environment significantly improves, be mainly reflected in the air that efficient heat exchange makes to flow through obtain lower dew point and separate out more juicy, connecting inner structure is kept the moisture of separating out here more, comprehensive above when equal evaporating temperature, the present invention can reduce about half than its air-out water content of existing air-conditioner, greatly improves effect on moisture extraction.
The dehumidification mode that traditional air conditioner is taked when room temperature is lower realizes dehumidifying by intermittently starting refrigeration compressor, and which can cause making people feel cold when compressor operation, makes us producing unhappy sensation when compressor stops.When the present invention can reduce room temperature in these cases hardly, continuous dehumidifying produces dry and comfortable air, allows people feel as snug as a bug in a rug.
As below 20 DEG C, the clammy season of relative air humidity more than 95%, can reduce and even close room temperature control valve, air directly blows out by no longer lowering the temperature after the dehumidifying of dehumidifying heat pipe also backheat, air-out relative humidity can about 35%, and by the heat exchange of return air channel and inlet channel air, last leaving air temp can reach 18 DEG C, the air of this temperature is estimated after entering indoor circulation only to reduce within room temperature 1 DEG C, but significantly can reduce air humidity.And conventional air conditioner at the temperature disclosed above, leaving air temp can, below 12 DEG C, in order to satisfied dehumidifying needs, make the indoor of original low temperature can become colder and increase power consumption.
" dehumidification mode " that conventional air conditioner is provided with, may be provided in temperature lower when adopt, when " dehumidification mode ", refrigeration compressor intermittent running constantly reduces to prevent room temperature, also avoids evaporimeter to occur frosting.Simultaneously; the speed of service of breeze fan can reduce when " dehumidification mode "; sometimes slowly; that air is too fast flows through evaporator surface in order to prevent; causing because heat exchange is insufficient steam have little time condensation and affect effect on moisture extraction, also preventing the excessive water droplet being attached to evaporator surface of wind-force from blowing toward indoor.But problem is: the excessive cycle of compressor start-stop, the change wave amplitude of indoor temperature and humidity can be caused excessive, people is allowed to have sense of discomfort, if the cycle of compressor start-stop is too short, because frequent starting can reduce its life-span, and increase power consumption, and breeze fan slows down and also can affect the mobility of room air, and people can be allowed to feel unhappy.
The present invention improves above-mentioned condition completely, when low temperature adopts " dehumidification mode ", the flow-control of refrigerant obtains and seldom even closes by room temperature control valve, the cold that compressor operating produces, almost concentrate on the region release of the dehumidifying heat pipe below combined evaporimeter, the cold finally taken away due to the air flowing through combined evaporimeter is little, the latent heat of the mainly water vapor condensation phase transformation of actual consumption cold, and generally latent heat energy consumption account for refrigeration total amount ratio little, even if compressor break-off, cold stored by combined evaporimeter inside can maintain long period consumption, thus the compressor operating resting period can extend greatly, fast in refrigeration, consume cold slow situation order compressor operating time scale reduce, quit work period at compressor, breeze fan can preserve normal air output always, as long as the temperature below combined evaporimeter is still low, its dehumidification function just can maintain always, as being connected in series constant pressure valve between evaporimeter and compressor, or adopt frequency-changeable compressor or digital scroll compressor, constant evaporating pressure and minimizing cold medium flux when simple dehumidifying, compressor underload can be made to operate continuously, dry air can be produced continuously and less reduce room temperature, continue the humidity keeping room air suitable, temperature and mobility, and it is very energy-conservation.
The present invention when low temperature dehumidification by the commutative sensible heat of about ninety percent of combined evaporimeter, leaving air temp can be allowed close to EAT, namely being used for the power consumption of air cooling-down part during dehumidifying is about 10% of conventional air conditioner, so compared with conventional air conditioner, when dehumidifying, the load of compressor will be lacked a lot, no matter be continuous operation or discontinuous operation, its energy-saving effect all clearly.
The present invention controls the refrigerating capacity of dehumidifying heat pipe by control refrigeration compressor or choke valve, and the water content of adjustable air-out, is strengthened by the regulating valve flow that regulates the room temperature or reduce the refrigerating capacity of air outlet heat pipe, the cooling extent of adjustable air-out.
If dehumidification requirements scope allows, the evaporating temperature of the inner refrigerant of dehumidifying heat pipe can be relatively fixing, and choke valve can adopt capillary.
The heat-conducting medium of dehumidifying heat pipe and air outlet heat pipe internal circulation flow can be the circularly cooling working medium that refrigeration compressor directly provides, also can be the circulating frozen liquid be made up of refrigeration system, the effect produced is similar, overlapped combined evaporimeter between respectively and by multi-pipeline branch cold water more and circulate, can be applicable to central air conditioning project.
The air outlet heat pipe of combined evaporimeter can belong to same heat exchange circulation loop with dehumidifying heat pipe, also three-way valve can be set respectively at air outlet heat pipe gateway end and switch connection peripheral conduits, air outlet heat pipe and dehumidifying heat pipe can be made independently to belong to different heat exchange circulation loops respectively separately.When indoor need conveying warm braw and dehumidify simultaneously, air outlet heat pipe can coordinate with other heat exchange circulation loop, realizes the function that the air after to dehumidifying heats.
