Description
Technical field
The utility model relates to electro-mechanical arts, is specifically related to a kind ofly adopt inverse double-rotation wing fan and freeze or the device of heating efficiency to improve as condenser or evaporimeter in conjunction with microchannel or thin passage.
Background technology
According to statistics, current architectural energy consumption accounts for whole society's total energy consumption close to more than 35%.As can be seen here, architectural energy consumption occupies very important ratio in China's power consumption total amount.Architectural energy consumption mainly comprises heating, air-conditioning, ventilation, hot water, illumination, electrical equipment etc., the energy consumption of wherein heating, air-conditioning, ventilation accounts for again building energy consumption more than 2/3rds, according to relevant statistics, the power consumption of northern China heating districts heat supply heating accounts for more than 65% of the total power consumption of building, and some areas are even up to 90%.In building power consumption, the use of air-conditioning is the equipment that in building energy consumption, power consumption is maximum.Beijing refrigeration can finding show, and in all public buildings in Pekinese, market accounts for 5% of construction area.Wherein adopt the power consumption Que Zhan whole city building energy consumption overwhelming majority of central air-conditioning building, Inst energy consumption is formed primarily of building energy consumption, and it occupies 70% of public organizations' total energy consumption.And building 35% of power consumption.Have influence on people in the extremely serious especially haze weather of current environmental pollution to live every aspect period, haze is not only harmful to human body, and affects the production of crops, and this is extremely difficult tasks to energy-saving and emission-reduction.Primary energy consumption rich and influential family is thermal power generation, secondary energy consumption rich and influential family is air-conditioning and heating, so we will adopt advanced technical method to reduce the very big dependence of heating and air-conditioning to electric power, widely popularize air energy heat pump heating system to replace traditional consumption fossil energy heating system, just carbon emission can be reduced, coal consumption just can be made to reduce.
Four large parts of air conditioner refrigerating: compressor, evaporimeter, condenser, cut-off equipment.And wherein the raising of compressor performance is one of topmost power-economizing method.But air conditioner compressed engine efficiency improves and unrestrictedly can not improve, no matter be current double stage compressor, or magnetic suspension compressor is all to overcome compressor mechanical wear, reduce air gap losses and have the raising of efficiency in mind, but never mutual repulsion intrinsic for refrigerant gas molecule can be reduced, currently mainly rely on high-efficient compressor, refinement product design, refinement is mated, and fully improves the ability of compressor, can obtain the energy-saving efficiency of air-conditioner.The more common way of the second is the area increasing air-condition heat exchanger, is improved the efficiency of air-conditioning by the heat exchange efficiency improving heat exchanger.In addition, can also realize energy-conservation with high-level heat transfer technology, to reduce the consumption of metal material.Also have some new and high technologies, do not realize high heat exchange efficiency completely by the increase of heat exchange area, strengthening research and development is in this respect that tool is of great significance.In a word thermodynamics tell our reverse mobile heat from environment temperature more away from more difficult, heat pump is exactly that so the larger heat transfer rate of forward heat transfer temperature difference is faster, and this is the truth who cannot run counter to, only have along its thermodynamics natural law, just can be more energy-conservation by elements.So, if inverse card circulation is still like this, be also by ambient air temperature to reach the efficient of Lang Ken circulation in Lang Ken cyclic process, when environment temperature gives power very much, its generating efficiency can be very high in Lang Ken circulation; Inverse Carnot cycle is also that so its refrigerating efficiency is very high when the temperature of the surroundings is low, and when environment temperature height, its heating efficiency is very high.Circulate and inverse Carnot cycle so utilize environment temperature can realize efficient Lang Ken, utilize environment temperature to reach and efficiently mainly to realize by heat exchanger, in thermal power generation Lang Ken circulates, we are difficult to realize exhaust steam latent heat major part and recycle, also be to adopt compressor that exhaust steam press-in boiler is all recycled to realize exhaust steam latent heat, if what like this just become has lost more than gain, the energy also more much more than the heat energy lost at cooling tower will be consumed, therefore mechanical system is adopted to strengthen thermodynamic cycle, and improving its cycle efficieny is have it circumscribed, the contrary consumption will saving many energy by power of nature.Rely on heat exchanger and environment temperature to carry out heat exchange thus and improve its exchange capability of heat and greatly can improve inverse Carnot's cycle efficiency.
Its condenser for outdoor environment temperature kind of refrigeration cycle, the circulation that heats for outdoor environment temperature is its evaporimeter, and the heat output of recirculation evaporator is by many factors, simple raising refrigerant flow, adopt large circulating ratio, evaporimeter can not be made to obtain maximum heat output, increased the weight of the burden of compressor on the contrary.Improve the tube refrigerant flow velocity of recirculation evaporator, also the heat transfer mean temperature difference between cold-producing medium and air can be caused to reduce simultaneously, considering the effect of heat transfer coefficient and heat transfer temperature difference, in order to obtain maximum heat transport, just there is the problem of a best refrigerant flow rates.
Because refrigerant side exothermic coefficient is far longer than air side exothermic coefficient, so air side exothermic coefficient just becomes the upper limit of evaporimeter (or condenser) heat transfer coefficient, under the prerequisite not considering production technology and human body comfort, improve the heat transfer coefficient that air side exothermic coefficient can improve recirculation evaporator.The approach improving air side exothermic coefficient generally comprises: the flowing velocity improving air, adopts the modes such as the nest plate of various compound section shape.But improve air velocity and also can increase fan energy consumption and Load Evaporator simultaneously, so using the net refrigerating capacity of recirculation evaporator as object function, the best air quantity of recirculation evaporator can be obtained.So manufacture high-efficiency air-condition product to research and develop, each air-conditioning producer strengthens this respect research dynamics all in succession, comprise Gree, beautiful, Haier etc. all to pay special attention to outdoor machine of air-conditioner fan how can be made to produce larger air quantity as far as possible to improve overall efficiency not increasing in fan electromotor power and heat exchanger heat exchange area situation, and using being studied as very important problem here.

The course of work:
Comprise the following steps:
Process of refrigerastion:
(1) compressor is by the gaseous state of gaseous refrigerant boil down to HTHP;
(2) gaseous refrigerant of HTHP enters into outdoor air heat exchanger by pipeline, now outdoor air heat exchanger is condenser, and the gaseous refrigerant of HTHP becomes the liquid refrigerant of normal temperature after exchange heat release latent heat by outdoor air heat exchanger;
(3) air heat exchanger normal temperature liquid refrigerant out enters the thin passage of plate-fin adverse current or micro-channel heat exchanger by pipeline and throttling arrangement outdoor, and the latent heat that normal temperature liquid refrigerant absorbs opposite side refrigerant fluid at the thin passage of plate-fin adverse current or micro-channel heat exchanger by evaporation becomes normal temperature gaseous refrigerant;
(4) again compressor is entered from the thin passage of plate-fin adverse current or micro-channel heat exchanger normal temperature gaseous refrigerant out by pipeline and cross valve, the gaseous refrigerant of the gaseous refrigerant boil down to HTHP of normal temperature is entered outdoor air heat exchanger by compressor, carries out next one circulation;
(5) fluid of the thin passage of plate-fin adverse current or non-brake method agent side, microchannel becomes refrigerant fluid after release latent heat, this refrigerant fluid is recycled pump and squeezes into room conditioning end and get back to again in the thin passage of plate-fin adverse current or micro-channel heat exchanger after carrying out exchange heat with room air and carry out exchange heat with cold-producing medium, completes the whole cyclic process of refrigerant fluid;
Heating operations:
(1) by cross valve electric control gear, outdoor air heat exchanger is switched to evaporimeter, and the thin passage of plate-fin adverse current or micro-channel heat exchanger switch to condenser;
(2) compressor air heat exchanger draw gaseous cold-producing medium high-temperature high-pressure refrigerant gas is pressed in the thin passage of plate-fin adverse current or micro-channel heat exchanger outdoor;
(3) high-temperature high-pressure refrigerant warms up matchmaker's fluid with this heat exchanger opposite side and fully carries out exchange heat in the thin passage of plate-fin adverse current or micro-channel heat exchanger, and high-temperature high-pressure refrigerant release latent heat gives liquefy cold-producing medium after warm matchmaker's fluid;
(4) liquid refrigerant is by pipeline and throttling arrangement, to come back under compressor suction effect in outdoor air heat exchanger and to carry out exchange heat with outside air, oneself just obtaining evaporating becoming gaseous refrigerant again after acquisition outside air latent heat;
(5) gaseous refrigerant is entered in compressor again by pipeline and cross valve, completes refrigerant circulating process;
And the thin passage of plate-fin adverse current or micro-channel heat exchanger non-brake method agent opposite side fluid are warm matchmaker's fluids (6), after acquisition high-temperature high-pressure refrigerant latent heat, this warm matchmaker's fluid is heated up and is recycled pump and squeezed into air conditioning terminal, dispelled the heat in room by air conditioning terminal, after allowing room obtain suitable heating installation, warm matchmaker's fluid flow into again in the thin passage of plate-fin adverse current or micro-channel heat exchanger and carries out exchange heat with cold-producing medium, completes the cyclic process of warm matchmaker's fluid;
Inverse double-rotation wing fan is furnished with outside described outdoor air heat exchanger, inverse double-rotation wing fan is made up of two groups of fan assembly non co axial modes, and wherein one group is turn clockwise, and another group counterclockwise rotates, two groups of fan blade inclinations angle are contrary, but wind direction is consistent.
For improving efficiency of heat exchanger better, heating in situation, described joining by the outdoor air heat exchanger of inverse double-rotation wing fan and the corresponding condenser that must have is the thin passage of plate-fin adverse current or micro-channel heat exchanger with it, can certainly be plate type heat exchanger or shell-and-tube heat exchanger.
In embodiment 1-4, the thin passage of plate-fin adverse current or micro-channel heat exchanger are the thin passage of both sides plate-fin adverse current or micro-channel heat exchanger.
In embodiment 5-8, as shown in Figure 2, the thin passage of plate-fin adverse current or micro-channel heat exchanger are the three thin passage of side plate-fin adverse current or micro-channel heat exchangers, , on the basis of embodiment 1-4, thin for plate-fin adverse current passage or micro-channel heat exchanger are replaced to the three thin passage of side plate-fin adverse current or micro-channel heat exchangers, that side increased is used for carrying out exchange heat with running water to obtain health hot water, this side increased has a connection running water to enter 11, other end is connected to boiler 9 by pipeline, space can be saved like this, reduce unit floor space, and also greatly save cost of goods manufactured.Because in the winter time during operation of heat pump, its heating is consistent with product health hot water traffic direction, can there is mutual switching problem when the three thin passages of side plate-fin adverse current or micro-channel heat exchanger are used as evaporimeter and condenser when just cooling in summer runs.But this switching time is ofer short duration, because can complete very soon during health hot water in summer, and the air-conditioning water yield is little in heat exchanger, this part air conditioner water heating water is made also not hinder much losses, most critical this set can obtain the facility of defrost, accelerate defrost speed, utilize in the winter time the heat of boiler carry out defrost can realize maximization heat defrost technology application, heat the thin passage of plate-fin adverse current or micro-channel heat exchanger in situation and should be condenser, in refrigeration situation, the thin passage of plate-fin adverse current or micro-channel heat exchanger should be evaporimeter.
Under cooling condition, for the thin channel heat exchanger of plate-fin adverse current, we are also concerned about have a kind of coaxial double-rotor helicopter in space technology fields outdoor air heat exchanger in described circulation process 6, this lifting airscrew diameter is less than single-blade, but can play energy-saving effect.The flat aerodynamic characteristic that flies of coaxial double-rotary wing also has different from single rotor, and data shows, under identical pulling force and rotor diameter, the induced drag of rigid coaxial DCB Specimen is lower than single rotor by 20% ~ 30%.Because the quantity of control system part and these non-streamline shape parts of upper and lower rotor hub and volume are greater than single-rotor helicopter and expose in the gas flow, thus the useless resistance area of co-axial helicopter is greater than single-rotor helicopter.The required horsepower of co-axial helicopter when hovering, middle low-speed operations is less than single-rotor helicopter, increase with speed, required horsepower increases to single-rotor helicopter gradually, and this characteristic determines co-axial helicopter larger practical ceiling, larger climbing speed, larger cruising time.The main distinction of co-axial helicopter and single rotor tail-rotor helicopter adopts two of upper and lower contrarotation groups of rotors to be used for balancing rotor torque, do not need tail-rotor.Structurally, owing to adopting two secondary rotors, compared with the single-rotor helicopter of identical weight, according to identical disk loading, its rotor radius is only 70% of single-rotor helicopter.Also has a kind of double-deck fan, this fan has low-noise strong blast volume, trace it to its cause is that although pressing due to every individual layer rotor wind pectinid is all forward, wind advances with swirling manner because the special tectonic of the dual reverse fan wing, eddy current loss can be there is, will tall positive eddy current wind direction mutually if increase a rotor reversely rotated, impel vortex wind-force substantially to become towards just front wind-force, the loss of eddy current will be reduced, so not only increase air quantity, and the noise that eddy current brings can be reduced.
For these reasons, the utility model adopts inverse double-rotation wing fan to strengthen the heat exchanger exchange capability of heat of outdoor machine of air-conditioner (because increase the exchange capability of heat that air quantity can improve wind side, and then improve the coefficient of heat transfer of whole heat exchanger), and coordinate microchannel or thin channel heat exchanger as the evaporimeter of air-conditioning or condenser to strengthen the circulation rate of cold-producing medium in cooling and warming process.We know that compressor plays the very key effect of refrigerant circulation and phase transformation in kind of refrigeration cycle or heat pump cycle process, electric energy of its input of outer bound pair is mainly used to overcome the resistance of repulsion between gaseous refrigerant agent molecule and flow of refrigerant, also has the frictional dissipation between compressor motion parts.Between molecule, repulsion size is determined constant in fact, also only have and shorten fluid flow circuit distance just can reduce the resistance of fluid by improving pipeline, mechanical friction loss can adopt new high-tech material to reduce frictional dissipation between component of machine by improving Machine Design.However the pressure reduction that the high-pressure side that the power consumption of compressor is mainly also used to the low-pressure end and condenser overcoming evaporimeter causes, this magnitude of pressure differential can determine its compression ratio size, how to reduce the size of compression ratio? certainly mainly just be achieved by efficient condenser and efficient evaporimeter, because efficient condenser can be taken away the heat of condenser very soon, thus the Pressure Drop of condenser is got off; Efficient evaporimeter can be come in the heat absorption in the external world very soon, thus evaporimeter internal temperature is improved, and its internal pressure equally can be made to be improved, the ratio of low-pressure end and high-pressure side finally can be made to reduce, thus compressor power input is reduced accordingly.Can can the another kind of mode of thinking also reach the object played the same tune on different musical instruments? compressor power input is allowed to reduce exactly, thus evaporating temperature is uprised, condensation temperature step-down, make evaporating temperature and condensation temperature all close towards environment temperature direction, this just can make compression ratio diminish, existing air conditioning terminal cannot make cold close to environment temperature to meet the requirement of room refrigeration air-conditioner, also the warm matchmaker's hydro-thermal amount close to environment temperature cannot be made to fall apart to room the requirement of to reach calorific requirement, it is obviously not all right that neither one high-efficiency air-condition end coordinates with it, if existing fan coil chilled water temperature is higher than its room air conditioner effect non-constant when 10 DEG C, heating season is when warm matchmaker's coolant-temperature gage is lower than its heating effect non-constant when 45 DEG C in the winter time.Those skilled in the art can know that chilled water temperature its Energy Efficiency Ratio higher is larger when cooling in summer operating mode, and when cooling water temperature is lower, its Energy Efficiency Ratio is also larger; In operation of heat pump situation, when condenser temperature is lower, its Energy Efficiency Ratio is also higher in the winter time, and evaporating temperature its Energy Efficiency Ratio higher is also higher, and Energy Efficiency Ratio changes with variation of ambient temperature.Need to adopt various compressor to come the density of gaseous fluid to increase its density by compression in covert refrigeration technology field, that is mechanical means is adopted the potential energy of gas molecule to be transformed into the kinetic energy of gas molecule, and the mode that molecular kinetic energy shows be exactly this gas temperature level (gas molecule potential energy performance be gas molecule spacing, the namely density size of gas), only have and gas temperature is lowered, just can make high density gas phase transformation success, and cooling needs condenser apparatus; Be condensed when cold-producing medium becomes gaseous state again from liquid when and needed to absorb surrounding air latent heat, this just needs evaporator device.And compressor cans be compared to automobile, and condenser and evaporimeter are like loading and unloading equipment, and refrigerant circulation speed speed not only depends on the efficiency of compressor, depends on the efficiency of evaporimeter and condenser equally, and effect realizes the circulation of cold-producing medium therewith.And the power that compressor exports mainly is used for the mutual frictional dissipation that overcomes between refrigerant gas molecule between phase repulsive interaction and component of machine, the acting of repulsion larger associated compressors is more, magnitude of pressure differential is shown as in cooling flow, consider that back pressure situation just must quantize the size of compressor work by compression ratio, general limited compression ratio is at about 12 times, and normal refrigeration air-conditioner compression ratio is more suitable at 2 ~ 3 times, compression ratio its Energy Efficiency Ratio less is larger, improving the most economical mode of Energy Efficiency Ratio generally adopts raising evaporator temperature or reduction condenser temperature to realize, so refrigeration efficiency ratio (EER) is higher when environment temperature is lower, its Energy Efficiency Ratio (COP) is heated higher when environment temperature is higher.That is when condensation temperature its condensing pressure lower is also lower, it is just much easier that compressor work overcomes high pressure; When evaporating temperature is higher, its evaporating pressure is also higher, and the refrigerant gas back pressure so entering compressor is also just high, and therefore during compressor suction refrigerant gas, its power output also just reduces.Thus can expect that the evaporation rate of cold-producing medium and condensation rate need efficient evaporimeter and condenser more more.In real production practices with life, we can observe: sometimes adopt the comparable mechanical system of heating power mode more convenient and more economically, for example: mechanical impact is difficult to metal device is out of shape or cracking sometimes, and can metal objects be caused easily to damage by expanding with heat and contract with cold.For another example thermal power plant realizes thermodynamic cycle by means of cooling tower, but be difficult to, by compressor, the steam doing merit is pushed back boiler again and carry out thermodynamic cycle, according to compressor, steam press-in boiler is circulated, seem that exhaust steam latent heat is all used, abandon enthusiasm condition as there is no cooling tower to occur, but this loses more than gain, because this will consume more electric energy carry out by compressor acting of calming the anger.Etc. these be all enough to illustrate mechanical means sometimes not as thermal methods come economy, if the strength only by means of environment just can make Lang Ken circulate and become more economically against card circulation, because all thermodynamic cycles all realize with reference to environment temperature, depart from its Energy Efficiency Ratio of the larger transfer of heat of environment temperature lower (no matter being freeze or heat).Changeless for compressor overcomes refrigerant gas intermolecular phase repulsive interaction, improve compressor to make it become to be nothing but efficiently to allow institute in compressor operating process run into frictional resistance to become less, so the space of being improved the efficiency of whole kind of refrigeration cycle by compressor is not very large.And the effect that the efficiency improving evaporimeter and condenser can make the efficiency of whole kind of refrigeration cycle improve can be far longer than the raising effect of compressor, this is because high-efficiency evaporator can make evaporator pressure uprise, efficient condenser can make its condensing pressure step-down, thus compression ratio is diminished, Energy Efficiency Ratio is improved.
Those skilled in the art know that its heat exchange efficiency of countercurrent heat exchange method is greater than following current, cross-flow, comprehensively flows mode, because its mean temperature difference of countercurrent heat exchange method is maximum, and the temperature difference is the power of heat transfer.Countercurrent flow can make it by the fluid of the heat exchange out temperature that enters of temperature approaches heat exchanging fluid, and its end difference also can be very little, and this is conducive to heat and is fully used.Heat transfer fluid channels diameter is more close to fluid molecule free path in addition, and its molecular kinetic energy is more easily transmitted, and its heat exchange efficiency is higher.Also have the application of field-synergy theory in technical field of heat exchange, its correctness of sufficient proof, field-synergy theory wherein topmost field coordination refers to: in adverse current situation, the cosine angle of velocity field two vector of temperature gradient field and fluid cross-section goes to zero and its heat exchange efficiency just can be made to be maximum, temperature gradient field and velocity field how is made to reach high efficient heat exchanging object? the method of its means and realization mainly distributes to reach cross section flow velocity uniformity by both sides fluid well-distributing, thus can realize that temperature gradient field is corresponding occurs that cross-section temperature is in the same size, Here it is key problem in technology point, can so how, just obtain this consistent size? drag size just by each tiny fluid passage of heat exchanger is consistent, flow process length is equal, just can realize two side liquids can both flow velocity of the same size, the gradient that temperature is consistent, thus homonymy heat exchange can be avoided to lose and return heat loss.Fluid inlet and outlet direction in heat exchanger both sides is very exquisite in addition, go out after must following precursor, after the advanced principle of the person of going out, if design of heat exchanger does not follow this principle, it is also efficiently be difficult to realize, the reason that this principle do not followed by current many heat exchangers considers that it imports and exports layout cannot go realization problem according to this principle mostly, inside its tangible same volume, as long as its internal flow is flowing, its inside must have barometric gradient to be existed, barometric gradient exists and a part of fluid will be caused to take a shorter way cause cross section flow velocity uneven, so just affect heat transfer effect.
Hunan Chuanghua Low-carbon Environmental Protection Technology Co., Ltd. make use of the thin passage of plate-fin and the micro-channel heat exchanger (patent No.: 201210076080.X) that this principles of science of field-synergy theory and technique study go out a kind of efficient reverse streaming thus, this heat exchanger can be used as the condenser in the evaporimeter of kind of refrigeration cycle in the utility model and heat pump cycle, tentatively test through model machine, find that model machine Energy Efficiency Ratio in environment temperature 31 DEG C of situations is up to 6.2 times.100L water rises to 55 DEG C from 25 DEG C and has spent less than 16 minutes, and input system general power is 1980W, and compressor rated power is 2100W, and when electric current rises to 13.2A from 9.8A always, hot water reaches 55 DEG C, input voltage 220V.When adopting directly-heated mode (acyclic mode) to heat, its Energy Efficiency Ratio can up to 6.8 times, and directly-heated mode is higher than the Energy Efficiency Ratio of endless form.When inflow temperature rises to 55 DEG C from 6 DEG C, the health hot water of 100L55 DEG C needs 26 minutes, and its Energy Efficiency Ratio reaches 6.1.Etc. test of many times show that efficient condenser is had great potentialities can dig for raising air-source water heater Energy Efficiency Ratio aspect, and the active force of high-efficient compressor can be defeated completely.Hunan Chuanghua Low-carbon Environmental Protection Technology Co., Ltd. not yet adopts when DC bipolar compressor and Energy Efficiency Ratio just can be made to break through 6 times, arrive meeting the epoch of 6 times of Energy Efficiency Ratio air energy without doubt, Energy Efficiency Ratio will be made to break through 7 ~ 8 times according to direct current compressor, because the comparable common AC compressor efficiency of direct current compressor is high by about 20%, because asynchronous machine is induction machine, energy to be absorbed set up motor main field from electrical network, cause certain energy loss; In brushless DC motor rotor, rare earth permanent-magnetic material is installed, establish rotor field, no longer absorb power grid energy and set up motor-field, rotor and stator field synchronous operation, without induced current in rotor windings, eliminate rotor resistance copper loss and magnetic hystersis loss, save electric energy, improve electric efficiency.Brshless DC motor, compared with asynchronous machine, can reduce stator current 15%, can improve operational efficiency about 20%.
The utility model sums up above-mentioned a variety of causes and single technical advantage exactly, creatively be used in air-conditioning products field, this is not just simply the application of multiple different technologies in different field, but be transplanted to air-conditioning products field after allowing the technology of multiple different field be transformed, the utility model comprises tri-layer innovation: first level innovation adopts double-rotor machine principle well, the rotor one being considered as positive rotation is fixed on outer rotor output shaft, and so another reverse rotor is just fixed on internal rotor output shaft; Second level innovation is that an inverse double-rotation wing fan assembly is used in against on outdoor air heat exchanger in Carnot cycle; The innovation of 3rd level is exactly combine the thin passage of plate-fin adverse current or micro-channel heat exchanger to be on this basis used for realizing cold-producing medium and refrigerant fluid or warm matchmaker's fluid and to carry out exchange heat.Creatively air-conditioning products Energy Efficiency Ratio can be made significantly to improve multiple technology multi-level combined innovation that organically blends, cost of goods manufactured can also be reduced, although air-conditioning products technology becomes better and approaching perfection day by day, but still also in constantly bringing forth new ideas, although I has also applied for a kind of air-conditioning hot water integrated machine (patent No.: 20140414705.8), its high efficiency is also verified, but energy-conservation amplitude is subject to a definite limitation, its in carnot's cycle process in identical cooling and warming situation, compressor current can be made to reduce about 7%, embody refrigerant fluid or warm matchmaker's fluid with refrigerant heat exchanger process in very efficient, this is because have employed the thin channel plate fin heat exchanger of pure adverse current to make condenser or evaporimeter obtains efficient result, but the bottleneck of delivered heat has been there is when carrying out exchange heat with air, because only have so many for its air mass flow during outdoor air heat exchange, heat that air is taken away also only has so many, heat that air provides also can only be so many, therefore the overall heating capacity of unit or refrigerating capacity are much the same, only compressor current is saved about 7%.In order to solve this bottleneck, and when not increasing heat exchanger heat exchange area and fan electromotor power, the utility model adopts a kind of inverse double-rotation wing fan to reach this purpose, this technical scheme and existing coaxial double-rotor helicopter have a great difference, first the utility model is using motor as drive energy, and is adopt jet motor or combustion engine powered unlike existing coaxial double-rotor helicopter; Equally also be different from the DCB Specimen that existing double-deck fan adopts coaxial-type, and be confined on computer heat radiation.And the utility model is different, what it adopted is non-coaxial inverse double-rotation wing mode, instead of simple combined type utility model, it is the inverse double-rotation wing technology transformed, this inverse double-rotation wing technology can also be applied to the air-cooled of steam power plant, the cooling of petrochemical industry, mechanical electric apparatus, food medicine and other fields and oven dry.To be applied in air conditioner refrigerating and heat pump flowsheet mainly for outdoor air heat exchange, to reduce occupation area of equipment, and to improve heat exchanger efficiency, be certainly also fine for room air heat exchange.Prior difference it be non-coaxial or coaxial DCB Specimen, and adopt coaxial two external rotor electric machines to realize unlike existing double-deck fan, even if the utility model adopts double-rotor machine and two rotors is shared a motor, its rotor also not on same output shaft, and can realize applying more flexibly.
The main points of the utility model patent innovation are: use double-rotor machine that the inverse double-rotation wing is combined, can provide the cooling heat dissipation element of the low noise of efficient Wind Volume; Adopt the thin passage of efficient plate-fin adverse current or micro-channel heat exchanger with it outdoor air heat exchanger match; The thin channel plate fin heat exchanger of high performance counter current is adopted to do air conditioning terminal, to be applicable to the refrigeration air-conditioner of chilled water and warm matchmaker's water warm air-conditioning of 38 DEG C of 18 DEG C.
