Description

A kind of separately adjustable combined air-conditioner unit of fresh air that can be multi-joint
Technical field
The present invention relates to a kind of air-conditioner set, more particularly, to a kind of separately adjustable combined air-conditioner machine of fresh air that can be multi-joint Group.
Background technology
Preferable air-conditioning effect is realized, the degree of regulation requirement of Temperature and Relative Humidity of Indoor Air is not only met, in addition it is also necessary to protect Good indoor air quality is held, this needs exist for good ventilation measure, should at least meet minimum fresh air rate of ventilation Requirement.
According to existing air-conditioning products technical merit, even using independent fresh air handining unit, fresh air adjusts process Efficiency is low, energy consumption big, operating cost is high, but indoor air quality might not be highly desirable, sometimes even also no good cake.Industry It is interior well-known：Air conditioner load can be divided into indoor load and new wind load two parts, and wherein new wind load is resh air requirement and interior The product of outer air enthalpy difference.In the case of generally needing air-conditioning, the enthalpy difference of indoor and outdoor air is not low, so new wind load is not yet It is little.Resh air requirement is bigger, and new wind load is bigger, and corresponding air conditioning energy consumption is also bigger.Such as, summer need to carry out fresh air cold But dehumidification treatments, need Air Conditioning System unit to provide cold.Winter needs to carry out fresh air warming and humidifying process, needs Cooling and Heat Source unit provides heat.In the case of these, Cooling and Heat Source unit for fresh air adjust process needed for provide cold or heat and New wind load is at least equal, and fresh air adjusts the energy consumption of process generation and is almost proportional to new wind load.It is moist at some Climatic environment under, it is also big even than new wind load that Cooling and Heat Source unit adjusts the cold and hot amount for undertaking supply load by fresh air Many, because fresh air moisture load is big under wet environment, the cold that fresh air dehumidification process is consumed is more much bigger than aforesaid new wind load, And also want reheating to eliminate the sensible heat refrigeration duty effect that fresh air sends into generation behind room after fresh air dehumidification, otherwise it is difficult to reality The precise control of existing Temperature and Relative Humidity of Indoor Air.So, the fresh air under humid climate environment adjusts energy consumption and even more can not despise.If Fresh air is not separately adjustable, but another rising is processed after mixing with room air return air, then dehumidifying and reheating process are consumed Energy is bigger.At present the Cooling and Heat Source unit of many air-conditioning systems is using the source pump of both cooling and heating, although source pump exists There is a heat supply or cooling coefficient more than 1 when heat supply and cooling, the electric energy of consumption is more cold and hot than what Cooling and Heat Source unit was taken Load is little, but can not be said to be efficiency height, because the energy figure of electric energy is high.Because the electricity charge are expensive, current most consumers are come Say, operating cost is still very high.If fresh air reheating process uses electric heater heat supply, fresh air humidification to add using electric steam Wet device produces steam, and efficiency is lower, and operating cost is higher.Certain areas can adopt central heating, gas-heating or waste heat Heating, cost is slightly lower, but is limited to local available resources, and can not solve Cooling, and operating cost is also impossible to very low. So, great majority have the air-conditioning system of control venting practice, such as central air-conditioning often changes fresh air during design selection Gas number of times is set in alap level, to reduce the total energy consumption of fresh air regulation, now indoor air quality as far as possible Improvement degree will necessarily be limited by less ventilation rate.Especially in the workshop that some pollutant emissions are big It is interior, if for the strict standard of the control shortage of indoor pollutant concentration or supervision, owner takes to save operating cost Low ventilation rate, causes the no good cake of indoor air quality to be also what is be entirely possible to.But, with the labour protection of people Consciousness constantly strengthens and the pursuit standard continuous improvement to quality of the life, and from now on the professional standard of fresh air changes undoubtedly also can More and more higher.
The air-conditioning occasion of uncontrolled ventilation measure, indoor temperature and humidity control accuracy is poor, and if to realize that identical is divulged information Ventilation effect simultaneously meets the requirement of identical Temperature and Humidity Control, then the energy consumption of air-conditioning system is bigger.Venting practice is not controlled not Mean to divulge information, but rely on gravity-flow ventilation, ventilation rate is unstable, and randomness is big, it is impossible to accurately control, make Big into Temperature and Relative Humidity of Indoor Air fluctuation, control accuracy declines.The occasion of such as many employing split-type air conditioners does not just control to lead to Wind measure, typically by artificially to air-conditioned room door and window leave certain gap or intermittent opening door and window in the way of, Fresh air is allowed to pass through the infiltration or inflow of door and window randomness.This natural ventilation system can also be right under summer or humid climate environment The higher air-conditioning system of Temperature and Humidity Control required precision causes another to negatively affect：The refrigerating efficiency of source pump is reduced, from And increase the energy consumption of air-conditioning system.Its reason is as follows：First, outdoor air is sent directly into room by gravity-flow ventilation without any process Interior, new wind load is directly superimposed with original indoor load, and the load after superposition is all by interior circulation air-conditioner（Namely only process The indoor set of the air-conditioner of indoor circulation air, such as detachable air conditioner）Undertake.Secondly, under summer or humid climate environment, Outside air humidity is high, and fresh air moisture load is big, so heat moisture ratio reduces in the total load after superposition.In this case, for room For the higher air-conditioning system of interior aerial temperature and humidity control accuracy requirement, it is desirable to blasting humidity will reduce, then air Jing Machine dewpoint temperature after the refrigerant evaporator cooling and dehumidifying crossed in interior circulation air-conditioner also just must be reduced, so as to force system The evaporating temperature of cryogen also must be reduced.However, it can be seen from the operating characteristic of vapor-compression chiller, cold-producing medium evaporation Temperature is reduced, and the refrigerating efficiency of refrigeration unit is also just reduced, so the energy consumption of air-conditioning system increases.
CN103075769B discloses the fresh air control method and device of a kind of achievable energy regenerating and free cold supply, leads to Cross the device and be capable of achieving following fresh air and adjust process and energy-saving benefit.
Cooling season, reclaiming the energy in air draft is used for the cooling and dehumidifying of fresh air, can save a large amount of in cooling season Fresh air conditioner energy consumption.Heating season, reclaiming the energy in air draft is used for heating and the humidification of fresh air, can be in heating season section About substantial amounts of fresh air conditioner energy consumption.Transition season humid climate has under conditions of larger indoor humidity load, reclaims fresh air reheating During cold be used for fresh air precooling and dehumidifying be also equal to be reclaim pre-cooling of fresh air and dehumidification process heat be used for it is new The reheating of wind, therefore the refrigeration duty and thermic load of Fresh air handing process can be simultaneously reduced, can similarly save substantial amounts of sky Adjusting system energy consumption.
Under the conditions of dry hot climate, realize that the cooling of fresh air is adjusted using evaporation of water cooling capacity in outdoor air and be possible to The efficiency for making air-conditioning system is greatly improved, here it is a kind of embodiment of free cold supply, this cooling mode even can be in expansion Can also play a part of to reduce air-conditioning system total energy consumption while fresh air changes, be conducive to improving ventilation rate and change Kind indoor air quality.
But, the fresh air adjusting means that CN103075769B is provided can not independently undertake air-conditioning complete under full working scope and appoint Business, needs interior circulation air-conditioner to undertake the indoor temperature regulation task of cooling and heating season.In the season for needing dehumidifying, also need Want Cooling and Heat Source unit that the cold supplemented needed for dehumidification process is provided to the supplementary dehumidification heat exchange in the fresh air adjusting means.

Under conditions of cooling season, transition season humid climate or indoor humidity load are larger, the controlling party of fresh air and air draft Formula and flow route are as follows.In exhaust system, under the driving of fan II 109, room air（RA）First Jing air drafts entrance 101 is inhaled Enter, then flow successively through surface-type heat exchanger 102, exhaust system inside air channel 103, packed bed heat and mass exchanger 107 until Jing Wind exhausting outlet 112 is crossed as exhaust system air draft（EA）Discharge.In VMC, VMC internal bypass air-valve 215 and Two fresh air outlet valves 212 are closed, and the first fresh air outlet valve 214 is opened, under the driving of fan I 203, fresh air（FA）First Jing Fresh air inlet 201 is sucked, and then flows successively through sprayer 202, the first energy regenerating fresh air heat exchanger 204, fresh air cooling and dehumidifying Heat exchanger 205, VMC inside connection air channel 211, the second energy regenerating fresh air heat exchanger 213 through the first fresh air until send Air port 214 is used as air-conditioning（SA）Send.
Under conditions of cooling season, transition season humid climate or indoor humidity load are larger, for realize energy regenerating with The water of free cold supply or the operation principle and feature of water solution cycle system are as follows.Water or the switching control of water solution cycle system model Valve processed 81 is closed, and is to realize full heat for realizing that full thermal energy is reclaimed on water or water solution cycle system parenchyma with free cold supply The water or water solution cycle system of energy regenerating.In packed bed heat and mass exchanger 107, not only due to temperature of outgoing air is low so that following Ring water or the aqueous solution transmit sensible heat and are cooled down to air draft, are also evaporated recirculated water or the aqueous solution because air draft humidity is low Cooling, the latter is substantially exactly latent heat transmission.So, realize from air draft to recirculated water in packed bed heat and mass exchanger 107 Or the process of the complete hot cooling capacity of aqueous solution transmission, that is, the recovery of the complete hot cold of air draft.Obtain following for complete hot cold recovery Ring water or the aqueous solution will flow to the first energy regenerating fresh air heat exchanger 204 under the conveying of circulating pump I 31 effect, in the heat exchanger It is interior that the even dehumidification process of the cooling to fresh air is realized by heat exchange, so as to the complete hot cold transfer most reclaimed from air draft at last To fresh air, that is, realize the complete hot cold recovery transmittance process from air draft to fresh air.Water or the aqueous solution are circulated, So this complete hot cold recovery process is continuously carried out.And be used to realize sensible heat energy regenerating with free cold supply Water or water solution cycle system mainly realize the water or water solution cycle system of sensible heat energy regenerating.Sensible heat energy regenerating is circulated In system, under the driving of circulating pump II 41, water or the aqueous solution will be changed in the second energy regenerating fresh air heat exchanger 213 and surface-type Circulate between hot device 102, realize continuous sensible heat energy recovery process.In the circulation of sensible heat energy regenerating, mainly sensible heat Heat energy Jing surface-type heat exchangers 102 first are passed to water or the aqueous solution in circulation, then Jing the second energy regenerating fresh airs by air draft Heat exchanger 213 passes to fresh air by the water or the aqueous solution in circulation.Therefore, air draft obtains precooling, and fresh air obtains reheating.Due to row Wind is before into packed bed heat and mass exchanger 107 by precooling so that air draft can be produced in packed bed heat and mass exchanger 107 Preferably evaporation cooling effect, makes the recirculated water or aqueous temperature that flow out from packed bed heat and mass exchanger 107 lower.For reality In water that now full thermal energy is reclaimed or water solution cycle system, water or the aqueous solution are always in packed bed heat and mass exchanger 107 and the Circulate between one energy regenerating fresh air heat exchanger 204.Therefore, relatively low packed bed heat and mass exchanger 107 goes out saliva or water Solution temperature also implies that the inlet temperature of the interior circulation water of the first energy regenerating fresh air heat exchanger 204 or the aqueous solution is lower, so as to Make fresh air obtain preferably cooling and effect on moisture extraction, advantageously reduce fresh air cooling and dehumidifying heat exchanger 205 except humidity load and its Associated heat pump refrigeration duty.Such regulation process can also produce other two kinds of possible incomes：One kind is cold indoors The larger situation of load, fresh air handining unit takes all of humidity load, allows more refrigeration dutys to be appointed by undertaking dehumidifying Business thus the higher interior circulation air-conditioner of Energy Efficiency Ratio are taken, and this is a kind of indirectly power save mode；Another kind is transition season tide Under conditions of moisture is waited or indoor humidity load is larger, indoor refrigeration duty is little, and by fresh air handining unit all of cold humidity load is taken Air-conditioning requirement can be met, then make fresh air acquisition reheating to save the energy needed for fresh air reheating by sensible heat energy regenerating Consumption.
Under conditions of cooling season, transition season humid climate or indoor humidity load are larger, fresh air cooling and dehumidifying heat exchanger 205 are used for supplementing the cold needed for cooling and dehumidifying is provided for fresh air.Fresh air is first in the first energy regenerating fresh air heat exchanger 204 Cooled down by energy regenerating and effect on moisture extraction.But fresh air water capacity at this moment is possible to still not low enough, in addition it is also necessary to enter one Step dehumidifying could meet the requirement of air-conditioning.Therefore, fresh air cooling and dehumidifying heat exchanger 205 is that the supplementary cooling for aiming at fresh air is removed It is wet cold to be provided and is designed.The fresh air handining unit for being provided with fresh air supplement cooling and dehumidifying heat exchanger can be according to whole air-conditioning The regulation task of the execution new wind state of the dehumidification requirements independence of system, especially fresh air humidity, so not only can keep sending out The advantage of fresh air handining unit energy regenerating and free cold supply is waved, and does not increase room conditioning unit (i.e. interior circulation air-conditioner) Humidity load, or even room conditioning unit can also be allowed only to undertake sensible heat refrigeration duty, it is possible to make room conditioning unit with compared with High refrigerant temperature carries out cooling, is the working condition for improving Cooling and Heat Source unit and the coefficient of refrigerating performance creation for improving Cooling and Heat Source unit Advantage.
Under conditions of cooling season, transition season humid climate or indoor humidity load are larger, moisturizing supply and condensed water are returned Receipts process and feature are as follows.In evaporation cooling procedure in packed bed heat and mass exchanger 107, the portion in recirculated water or the aqueous solution Moisture is divided to be evaporated.In addition, in order to maintain stablizing for system interior circulation water or aqueous solution water quality, a part of water or the aqueous solution are necessary Drain, excretion can be controlled by draining valve 104.So be accomplished by by supplement water come maintain fresh air handining unit interior circulation water or The mass balance of the aqueous solution.For this purpose, supplementing water can provide to VMC pond 206 first via water compensating valve 207, so Afterwards exhaust system pond 105 is delivered to via water or aqueous solution recovery pipe in the presence of pump or gravity, is followed so as to add to In ring water or the aqueous solution.At the same time, the first energy regenerating fresh air heat exchanger 204 and the surface of fresh air cooling and dehumidifying heat exchanger 205 The condensed water of upper generation will be moved first with the air-flow for flowing through, and VMC is then separated and be pooled to from air-flow Pond 206.This part water also will be delivered to exhaust system pond 105 and add to recirculated water by water or aqueous solution recovery pipe Or in the aqueous solution, the recycling of condensed water is realized, reduce the consumption of moisturizing water resource.
Cooling season, interior circulation air-conditioner a3 works in refrigeration mode, the cooling ability and fresh air of interior circulation air-conditioner The dehumidifying effect of cooling and dehumidifying heat exchanger 205 is adjusted can pass through compressor rotary speed, interior circulation air-conditioner rotation speed of fan and choke valve The combination regulation measure of aperture is realized.Cooling season, adjusting the valve position of the a2 of three-way diverter valve I makes refrigeration belonging to interior circulation air-conditioner Agent pipeline L2 is connected with suction line L4 of compressor, and adjusting the valve position of the a7 of three-way diverter valve II makes refrigeration belonging to outdoor heat exchanger Agent pipeline L3 is connected with the gas exhaust piping L1 of compressor, adjusts the aperture of the a6 of choke valve II to full-gear, adjusts the a4 of choke valve I Aperture meet the requirement of the compressor air suction degree of superheat, make interior circulation air-conditioner be in reliable and stable refrigeration work state.Adjust Section compressor rotary speed can change the evaporating temperature of cold-producing medium, while the interior circulation air-conditioner cooling ability and fresh air needed for ensureing Cooling and dehumidifying heat exchanger dehumidifying effect.During indoor cooling load reduction, can also be by reducing interior circulation air-conditioner rotation speed of fan Regulation measure realize the regulation of interior circulation air-conditioner cooling ability, meet the needs of indoor air temperature regulation.Fresh air dehumidification During load reduction, it is also possible to realize fresh air cooling and dehumidifying heat exchanger 205 by reducing the regulation measure of the a8 apertures of choke valve III The regulation of outlet superheat refrigerant vapor degree, that is, the regulation of fresh air cooling and dehumidifying heat exchanger dehumidifying effect is realized, so as to full The requirement of sufficient fresh air humidity regulation.Basic thought according to optimization operation control theory understands, in system operation, can be with The energy saving optimizing fortune of system is realized by optimizing the measure of compressor rotary speed, interior circulation air-conditioner rotation speed of fan and throttle valve opening OK.
Under conditions of transition season humid climate or indoor humidity load are larger, interior circulation air-conditioner a3 may operate in refrigeration Pattern, it is also possible to work in heat supply mode, the cooling or heat capacity and fresh air cooling and dehumidifying heat exchanger of interior circulation air-conditioner 205 dehumidifying effect is adjusted also can be adjusted by the combination of compressor rotary speed, interior circulation air-conditioner rotation speed of fan and throttle valve opening Section measure realization, can also adjust if necessary the mode of operation and rotation speed of fan of outdoor heat exchanger.Transition season humid climate or room Under conditions of interior humidity load is larger, if interior yet suffers from supplying refrigeration duty, the mode of operation of Cooling and Heat Source unit and regulation to arrange Grant cooling season identical.If interior needs heat supply, such as under conditions of outside air temperature is relatively low, then adjust three-way diverter valve I The valve position of a2 makes the affiliated refrigerant line L2 of interior circulation air-conditioner connect with the gas exhaust piping L1 of compressor, makes interior circulation air-conditioner In supplying hot working.Now, the mode of operation of outdoor heat exchanger a5 is needed according to the thermal balance of refrigerant circulation needs It is fixed.If indoor heating load is big, fresh air cooling and dehumidifying heat exchanger except humidity load it is little, outdoor heat exchanger may need to work in Refrigerant evaporator pattern, realizes meeting refrigerant circulation thermal balance needs from outdoor environment heat absorption., whereas if indoor heating Load is little, fresh air cooling and dehumidifying heat exchanger except humidity load it is big, outdoor heat exchanger may need to work in refrigerant condenser mould Formula, to outdoor environment heat extraction refrigerant circulation thermal balance needs are met.Adjusting the valve position of the a7 of three-way diverter valve II makes outdoor heat exchange The affiliated refrigerant line L3 of device is connected with suction line L4 of compressor and outdoor heat exchanger can be made to work in refrigerant evaporator mould Formula, adjusting the valve position of the a7 of three-way diverter valve II makes the affiliated refrigerant line L3 of outdoor heat exchanger connect with the gas exhaust piping L1 of compressor It is logical that outdoor heat exchanger can be made to work in refrigerant condenser pattern.When interior circulation air-conditioner works in heat supply mode, by pressure Contracting machine rotating speed, interior circulation air-conditioner rotation speed of fan, outdoor heat exchanger mode of operation and rotation speed of fan, the combination of throttle valve opening are adjusted Section measure can simultaneously realize the regulation of interior circulation air-conditioner heat capacity and fresh air cooling and dehumidifying heat exchanger dehumidifying effect, meet room The needs that interior aerial temperature and humidity is adjusted.Basic thought according to optimization operation control theory understands that optimum organization regulation parameter is also The optimization and energy saving of feasible system.
Heating season, fresh air and the flow route of air draft are identical with cooling season in fresh air handining unit, but fresh air The appropriateness of return air control valve 210 on pipe F1 is opened, to realize the mixing of fresh air and part indoor return air, it is ensured that through sprayer The enough height of 202 mixing air wet-bulb temperature, so as to reach the effect for freezing or crystallizing that prevents from spraying.When outdoor air temperature The sufficiently high return air control valve 210 without causing when spraying icing or crystallization, to close on fresh wind tube F1 of degree.For not having The area that spraying freezes or crystallization is dangerous, can cancel completely the return air control valve 210 on fresh wind tube F1.
Heating season, for realizing water of the energy regenerating with free cold supply or operation principle and the spy of water solution cycle system Levy as follows.Water or water solution cycle system model switching control valve 81 are closed, for realizing that full thermal energy is reclaimed and free cold supply Water or water solution cycle system parenchyma on be to realize water or water solution cycle system that full thermal energy reclaims.Full thermal energy is reclaimed In circulation, due to the temperature and humidity of air draft it is higher, not only to water or water-soluble when packed bed heat and mass exchanger 107 is flow through in air draft Liquid transmits sensible heat heat energy, also by water recovery to water or aqueous solution transmission latent heat energy, that is, realizes air draft to water or water The full heat energy transmission of solution, that is, the recovery of the full heat energy of air draft.The recirculated water or the aqueous solution for obtaining full energy recovery will The first energy regenerating fresh air heat exchanger 204 is flowed under the conveying effect of circulating pump I 31, heat exchange reality is passed through in the heat exchanger Heating existing to fresh air simultaneously coordinates spraying to realize humidification process process, so as to the complete hot heat energy transfer for most reclaiming from air draft at last To fresh air, the complete hot energy recovery transmittance process from air draft to fresh air is realized.As cooling season, full thermal energy was reclaimed Journey is also what is be carried out continuously.So-called cooperation spraying realizes that fresh air humidification is referred to and spray into mist in fresh air air-flow by sprayer 202 Change water or the aqueous solution, these atomized waters or the aqueous solution are flowed into fresh air and added in the first energy regenerating fresh air heat exchanger 204 Heat, the droplet evaporation carried secretly in fresh air, makes fresh air obtain the effect of humidification.Therefore, full thermal energy reclaims in circulation air draft and new Wind carries out caloic exchange simultaneously, their overall flow rate thermal capacity approximate match, makes full thermal energy reclaim the energy regenerating of circulation Efficiency is optimized.Reclaimed by full thermal energy and circulated, fresh air is possible to be humidified to a suitable moisture condition, so as to can The needs of further humidification can be removed from.It is main with the water of free cold supply or water solution cycle system for realizing sensible heat energy regenerating It is the water or water solution cycle system for realizing sensible heat energy regenerating.In the sensible heat energy regenerating circulatory system, in circulating pump II 41 Under driving, water or the aqueous solution will be circulated between the second energy regenerating fresh air heat exchanger 213 and surface-type heat exchanger 102, Realize that sensible heat energy regenerating is circulated.Sensible heat energy regenerating circulation in, mainly sensible heat heat energy Jing surface-type heat exchangers 102 first by Air draft passes to water or the aqueous solution in circulation, then the second energy regeneratings of Jing fresh air heat exchanger 213 is passed by recirculated water or the aqueous solution Pass fresh air.Therefore, air draft obtains precooling, and fresh air is reheated.Because air draft and fresh air in the circulation of sensible heat energy regenerating Mass flow amount approximately equal, and Exchange of apparent heat is substantially, so their flowing thermal capacity is conducive to excellent also with regard to approximate match Change the efficiency of sensible heat energy regenerating.Meanwhile, in the circulation of sensible heat energy regenerating, the humidity of air draft is almost unchanged.When outdoor air temperature When spending relatively low, after sensible heat energy regenerating, the temperature and humidity of air draft is still high than the temperature and humidity of outdoor air, also has There are the potentiality that full thermal energy is reclaimed.Therefore, flow into can be to enter after packed bed heat and mass exchanger 107 with water or the aqueous solution for air draft Row Total heat exchange, by remaining full thermal energy recirculated water or the aqueous solution are passed to, so as to also be capable of achieving by water or the aqueous solution Full thermal energy reclaims the full thermal energy of circulation and stress air draft and passes to the process of fresh air.Because sensible heat energy regenerating and full heat energy It is approximate match that amount reclaims the thermal capacity of air draft and fresh air in two stages all the time, optimizes the effect of whole energy recovery process Rate.
Heating season, fresh air cooling and dehumidifying heat exchanger 205 need not provide any heating amount or refrigerating capacity.
Heating season, the operation principle and feature of spraying system is as follows.First, to be injected into water or the aqueous solution need to be from air draft System pond 105 or VMC pond 206 suck, depending on the strobe state of triple valve III 51.The water or the aqueous solution of suction Spraying system delivery pump 52 will be flowed to through triple valve III 51, then sprayer 202 will be delivered to simultaneously by spraying system delivery pump 52 In spraying into fresh air air-flow.
Heating season, moisturizing supply and condensing hot air furnace process and operating characteristic are described as follows.Spray water or the aqueous solution can To come from VMC pond 206, exhaust system pond 105 is may also come from.Unevaporated spray water or the aqueous solution are final VMC pond 206 will be separated and fallen into from fresh air air-flow, or further Jing water or aqueous solution recovery pipe are delivered to Exhaust system pond 105, hence into recycling.In the first energy regenerating fresh air heat exchanger 204, spray water or the aqueous solution will Part or all of moisture is lost because of evaporation.In addition, in order to maintain stablizing for system interior circulation water or aqueous solution water quality, a part Water or the aqueous solution will be drained by draining valve 104.So be accomplished by by supplement water come maintain fresh air handining unit interior circulation water or The mass balance of the aqueous solution.For this purpose, supplement water can Jing water compensating valves 207 provide to VMC pond 206, or enter one Step Jing water or aqueous solution recovery pipe be delivered to exhaust system pond 105, so as to add to system circulation water or the aqueous solution in. In caloic exchange process in packed bed heat and mass exchanger 107, the part vapor in air draft will condense and be added to recirculated water Or in the aqueous solution.Under the conditions of clean room air, this partial coagulation water is likely to enter spraying with recirculated water or the aqueous solution Circulation, to compensate the moisture of spray evaporation process consumption, this is also the recycling of condensate.Also do not arrange under heating season operating mode Except the interior generation for also having condensed water of surface-type heat exchanger 102.If having condensed water in the air exhaust heat exchange device 102 of surface-type, Directly it is pooled to exhaust system pond and is recycled.
Heating season, fresh air need not dehumidify, and the mode of operation of interior circulation air-conditioner is heating mode, interior circulation air-conditioner Adjusting for heat capacity can be realized by the regulation measure of compressor rotary speed.Heating season, adjusts the valve position of the a2 of three-way diverter valve I The affiliated refrigerant line L2 of interior circulation air-conditioner is connected with the gas exhaust piping L1 of compressor, adjust the valve of the a7 of three-way diverter valve II Position the affiliated refrigerant line L3 of outdoor heat exchanger is connected with suction line L4 of compressor, regulation the a4 of choke valve I aperture to Full-gear, adjusts the aperture of the a8 of choke valve III to completely closed state, adjusts the aperture of the a6 of choke valve II to meet compressor The regulation requirement of suction superheat, makes interior circulation air-conditioner heat working condition in reliable and stable.Adjust compressor rotary speed The condensation temperature of cold-producing medium can be changed, such that it is able to change the heat capacity of interior circulation air-conditioner, indoor air temperature is met The needs of regulation.
Under the conditions of dry hot climate, the flow route of air draft is identical with cooling season, the control mode and stream of fresh air Path line is as follows.In VMC, the control valve of the first fresh air outlet 214 is closed, the He of VMC internal bypass air-valve 215 The control valve of the second fresh air outlet 212 is opened.Under the driving of fan I 203, fresh air（FA）First Jing fresh air inlets 201 are sucked, Sprayer 202 and fan I 203 are then passed through until VMC inside bifurcation mouth.Afterwards, fresh air air-flow is classified into two strands：One Stock will flow sequentially through the connection of the first energy regenerating fresh air heat exchanger 204, fresh air cooling and dehumidifying heat exchanger 205 and VMC inside Air channel 211, another stock will flow sequentially through VMC internal bypass air channel 216 and the second energy regenerating fresh air heat exchanger 213.Most Afterwards, two strands of air-flows converge and pass through again the second fresh air outlet 212 and as air-conditioning（SA）Send.
Under the conditions of dry hot climate, the water or the work of water solution cycle system circulated for energy regenerating and free cold supply is former Reason and feature are as follows.Water or water solution cycle system model switching control valve 81 are opened, and sensible heat energy regenerating is followed with free cold supply Loop systems circulating pump II 41 quits work, and two water or water solution cycle system merge into a circulatory system.In full thermal energy Under reclaiming the driving with free cold supply circulatory system circulating pump I 31, the recirculated water or the aqueous solution of discharge flow through a point three-channel parallel First energy regenerating fresh air heat exchanger 204, the energy regenerating fresh air heat exchanger 213 of surface-type heat exchanger 102 and second.Specifically It is exactly that reclaiming from full thermal energy will be firstly split into the recirculated water or the aqueous solution of the discharge of free cold supply circulatory system circulating pump I 31 Two strands of liquid streams：One will flow through the first energy regenerating fresh air heat exchanger 204, and another strand will flow through the first across loop connecting pipe 80.Then, second strand of liquid stream will be separated into two bursts of tributaries：One flows through surface-type heat exchanger 102, and another strand will flow through the second energy Amount reclaims fresh air heat exchanger 213.Then, this two bursts of tributaries converged and passed through the pipe before across the loop connecting pipe 82 of Article 2 Road.Next, from the mixing liquid of the outflow of the second across loop connecting pipe 82 and from the first energy regenerating fresh air heat exchanger 204 The liquid joint of outflow forms one liquid flow, finally flows successively through liquid distribution trough 108, packed bed heat and mass exchanger 107 and row Wind system pond 105 until flow back to full thermal energy reclaim with free cold supply circulatory system circulating pump I 31 and formed one it is complete Free cold supply is circulated.Water or the aqueous solution are contacted when flowing through packed bed heat and mass exchanger 107 with air draft, are dropped because evaporating cooling effect Temperature.Jing is circulated, when a part of recirculated water or the aqueous solution flow through surface-type heat exchanger 102, the water being cooled or the aqueous solution The air draft flow through will be in turn cooled down, air draft is entered before packed bed heat and mass exchanger 107 and is obtained precooling, such that it is able to fill out Preferably evaporation cooling effect is produced in material bed heat and mass exchanger 107, the temperature of the water or aqueous solution discharged from packed bed is made more It is low.It is also that Jing is circulated, the recirculated water or the aqueous solution of another part low temperature flow to the first energy regenerating from after packed bed discharge The energy regenerating fresh air heat exchanger 213 of fresh air heat exchanger 204 and second, and fresh air is cooled down by the two heat exchangers, from And produce more preferable fresh air cooling effect.Fresh air cooling and dehumidifying heat exchanger 205 can provide supplementary cold to flowing through Fresh air carries out supplementing dehumidifying.If into the drying that the fresh air of fresh air handining unit is enough, fresh air cooling and dehumidifying heat exchanger 205 can So that any cold need not be provided.Fresh air after cooled will be used as air-conditioning by the second fresh air outlet 212（SA）Send Go out.Air-supply（SA）Indoor air conditions are reached after wet more than the indoor waste heat of absorption.Room air again can be by being circulated back to fresh air The exhaust system of air-conditioner set produces evaporation cooling effect.That is, the evaporation cooling capacity of air draft initially also comes from Outdoor air.Therefore, this is the process of a free cold supply.This mode of operation not only make use of free cold supply, and because Fresh air flows through parallel the first energy regenerating fresh air heat exchanger 204 and the second energy regenerating fresh air heat exchanger 213, and flow resistance is low, Be conducive to improving resh air requirement so that fresh air handining unit is introduced more than minimum fresh air requirmente possible with favourable weather conditions Fresh air improving indoor air quality, while being also possible to reduce the energy consumption of whole air-conditioning system.
Under the conditions of dry hot climate, moisturizing supply process is identical with cooling season, and condensed water or unevaporated spraying It is as follows that water or the aqueous solution reclaim situation.If outdoor air sufficiently dry, it is not required that fresh air cooling and dehumidifying heat exchanger 205 is provided Cold realizes the supplementary cooling and dehumidifying of fresh air, then the recovery without condensed water, or even also needs to by spraying system in fresh air Spray water or the aqueous solution are provided, to realize the humidification of fresh air.Conversely, being likely to produce condensation in all fresh air heat exchangers Water.Condensed water or unevaporated spray water or the aqueous solution can be pooled to VMC water or water-soluble liquid pool and obtain recovery profit With its principle is identical with cooling season or heating season.
Under the conditions of dry hot climate, fresh air need not dehumidify, and interior circulation air-conditioner is in refrigeration work pattern, meet indoor Air temperature modification needs.Under the weather conditions, the aperture of the a8 of choke valve III is adjusted to full closing state, the tune of other regulating valves Section requires then identical with refrigeration season.Under the weather conditions, adjusting compressor rotary speed can change the evaporating temperature of cold-producing medium, from And the cooling ability of interior circulation air-conditioner can be changed, meet the regulation needs of indoor air temperature.
