Description

Air energy, air-refrigerating conditioning machine

The present invention be a kind of novel be the sweat cooling technology of the energy with the absorption of air, particularly relating to can be cold to wet bulb or the gas collection system below the cloud point temperature with gas refrigeration, purification, dedusting, noise reduction are the air conditioner of one.

Existing all kinds of evaporative air coolers, because of the vaporization ability weak≤90%, be difficult to make the cold wind outlet temperature to reach wet-bulb temperature.So refrigeration is relatively poor, can not be used for reducing environment temperature.On the other hand, output cold wind humidity is higher, and is accompanied by a large amount of not hanging drops of vaporization, indoor article goes rotten easily, corrosion, and human body mainly is humidity, two indexs of temperature to the requirement of controlled atmosphere amenity, thereby existing air-cooler can not get extensive use.

Existing window formula domestic air conditioning, its coefficient of refrigerating performance is lower＜and 3.5, the heat exchange coefficient of fin is also relatively poor, about 40w/m ²; So need bigger compression refrigeration and heat exchange air-supply power, not only energy consumption is bigger, its running noise is also higher.Secondly, for preventing loss of refrigeration capacity, and the inner sealing formula air-flow that adopts circulation, promptly extract indoor gas after evaporimeter helps the sheet cooling, continue row to indoor, and do not have gas purge system, indoor various apparatus, fabric, the foul smell that gas that evaporates and human epidermal, breathing, smoking are discharged, and float absurd creatures such as bacterium, outstanding dirt, and can't handle and discharge, also have oxygen content, the factors such as loss of air-anion concentration and water capacity have departed from people to controlled atmosphere environmental amenity, hygienic requirements.

Human body has clean level several respects of temperature, humidity, flow velocity, oxygen content, negative ion concentration and the gas of gas to controlled atmosphere environmental amenity, hygienic requirements, the controlled atmosphere requirement that obviously existing family expenses window air conditioner and air-cooler can not satisfy above several respects.

For creation conforms to the controlled atmosphere environment of above-mentioned requirements, in order to improve coefficient of refrigerating performance and heat exchange coefficient, for reducing the running noise of air adjusting machine significantly.The present invention adopt vibration, wetability preferably, face evaporimeter loose porous, that be arranged in parallel, can produce the mixed fully repeatedly vaporization space of enough and quick air-flow, produce the effect of micropore fuel factor and the aqueous solution surfactant when its secondary evaporator contacts with air-flow, can make the output gas flow of one-level refrigeration be lower than 1.5～3 ℃ of wet-bulb temperature.And secondary refrigeration reaches about the cloud point temperature, and water capacity of its output cooling flow changes less, even this like this refrigeration machine also has a refrigeration overcast and rainy.Less to gas-flow resistance because of this evaporimeter, required air-supply power is also less, need not consumed power and freeze to be finished by absorption of air fully, can make coefficient of refrigerating performance become tens of times raising.On the other hand, vibration, wetting evaporating film mask have the dust of absorption, floating bacterium and purify partly effects such as pernicious gas, noise reduction.So the present invention is that collection refrigeration, damping, gas purification, noise reduction are the system of one, can creates and conform to that people are comfortable, the controlled atmosphere environment of hygienic requirements.

See that accompanying drawing 1, one-level film-type evaporation refrigeration machine partly be made up of body and kestner long-tube evaporator (8) two.Body is made up of motor (1), retainer plate (2), main shaft (3) net window (4), fan (5), axial flow wind cover (6), branch pressing plate (7), bearing block (21), bracing frame (22) guiding fan blade (20), connecting rod (19).The net window is the filtration of level air intake originally; Prime fan (5) works the wind effect that pushes away, and back level fan plays the air draught effect.Axial flow wind cover (6) and branch pressing plate (7) can prevent that gas backstreaming from forming strict blast district, to prevent the invalid loss of blast.Guiding fan blade (20) is regulated the direction of output gas flow, connecting rod (19) sync direction of fan blade (20) that can keep respectively leading.Kestner long-tube evaporator (8) is made up of water distribution system, evaporating film (25) and framework (12) etc., and framework (12) and the grid bar (15) that is parallel on it play a part evenly to open evaporating film (25).Screw rod (10) on tension link (9) and the framework is in order to regulate the uniform tension of each evaporating film.The spray pipe of parallel arrangement is uniform-distribution with micropore on (13), and the aqueous solution that oozes out from micropore is absorbed by water-release fibre layer (14), by the capillary conduction, gives equal water jacket (16) and evaporating film (25).That evaporating film (25) is selected is heat-resisting, corrosion-resistant, not perishable, have elasticity, hygroscopicity is better, the chemical fibre of surperficial fluffy characteristic and the loose hole cloth that is made into, and individual layer or stacking the closing of number form.All water jacket and water-release fibre are distributed to evaporating film (25), evaporating film by means of gravity and translocation capillaceous with the aqueous solution evenly and in right amount, make whole face be in wetting state.Ponding layer (24) in the water pond (23), evaporating film also can upwards supply water by means of capillary suction force.Add the surfactant that has long-chain hydrophobic group and short and small hydrophilic group molecular structure on a small quantity in the aqueous solution, as: chlorination octadecyl trimethyl quaternary amine etc.In order to surface tension that reduces the aqueous solution and the capillary conducting power that improves evaporating film.Because evaporating film has greater than self surface area of tens of times, aqueous solution surface area can be launched, and makes it enough dynamic evaporation surface areas greatly and as thin as a wafer.Water distribution valve (17) is in order to the water capacity of automatic control evaporimeter, water inlet pipe (18) but water receiving case or running water.

The saturated air district (27) that the film-type evaporation schematic diagram of refrigerating is seen accompanying drawing 3, evaporating film (25) both sides when outdoor heated dry air a by fan along → when being forced between evaporation diaphragm (25), the effect of entrainmenting because of air-flow a, mix with saturated air (27), when not vibrating as evaporating film, the dynamic saturated air thickness of its single face is 1, and evaporating film is waveform (26) vibration dynamically the time, and the dynamic zone of saturation thickness of its evaporating film single face can get rid of to shake and be extended to 1 ₁, the dynamic saturation region thickness between evaporating film is 21 like this ₁, and heated dry air can reach complete absorbing state in the shortest stroke L.During air-flow a forced flow, the interval between its evaporating film is wideer in the L stroke, and its air-flow dynamic pressure loss is also little.In the time of dynamically, the evaporation face is in the dewetting state, and the aqueous solution is membranaceous expansion as thin as a wafer on the evaporating film of bulk multi-hole, and surfactant can make this film thinner, and more even, the aqueous solution that is under this state very easily evaporates.The waveform of face is got rid of the motion of shaking on the other hand, has aggravated this evaporation process again.Face is that countless micropores are formed, can make the air that is pressed into micropore be in the compression febrile state during vibration, under certain air condition, the evaporation face is the isothermal evaporation temperature, be condensed to the isothermal evaporation temperature very soon so seal in the acoustic energy and the compression heating air of micropore, and its enthalpy is reduced.Surfactant can reduce the steam partial pressure of moisture film face, reduces the evaporation energy state of the aqueous solution, is embodied in lower isothermal evaporation temperature spot.This warm spot such as grade is lower than 1.5～3 ℃ of wet-bulb temperature, and output cold wind a' is complete absorbing state, also shows as this isothermal point value.Even thereby be in the external world refrigeration also arranged under the saturated air.This evaporimeter is that cold air directly contacts and absorption refrigeration with refrigeration working medium, and fabulous evaporation conditions is arranged again, thereby bigger heat exchange coefficient is arranged, and can reach 5000w/m ²This kestner long-tube evaporator because of the gas flow resistance is controlled in minimum, and has the bigger coefficient of heat transfer, and refrigeration energy major part is the absorption of air energy, so have high coefficient of refrigerating performance, cop can reach 30～200.Secondly the evaporation face of wetting attitude adsorbs dust, floating bacterium and the effect of pernicious gas partly in addition, and the dirt that is adsorbed by moisture film flows with moisture film and sinks to water pond (23), dust deposition wherein, because bacterium has the required nutrient of breeding, and can only dormancy or death; Pernicious gas in the dissolving water can absorb with active carbon.So the present invention is a high energy saving, low noise, collection refrigeration, gas purification, damping is the system of one.This system also can be used as a kind of dust catcher and uses as strengthening output, and the clearance rate of its dust is more than 99.9%.

This sweat cooling principle also can be made into idle film-type evaporation refrigeration machine.See accompanying drawing 4, idle membrane type schematic diagram of refrigerating.The automatic box haul of location fan blade (28) that is installed in the top changes and changes, and its direction of arrow is exactly the flow direction of wind; Ball (30) make this turn to automatically more flexible, make air intake (29) aim at natural wind a automatically, when a flow into kestner long-tube evaporator (8) from air intake and the refrigeration after, because proportion increases and the blast effect, make a' indoor along guide duct (32) input, adjusting valve (31) is in order to the flow of control a'.This refrigeration machine makes full use of natural wind and heat energy and freezes, and need not consumed power, even when outdoor wind-force is minimum, this machine still can utilize the weight power of cold wind a' and work on, so claim idle formula, promptly need not the power consumption merit.

Fig. 5 is a secondary Air regulation refrigeration machine master cutaway view of the present invention, and it is formed by body and compartment evaporimeter (35) and kestner long-tube evaporator (8) serial connection, and the water distribution principle unanimity of two evaporimeters repeats no more.Fig. 6 is the compartment schematic diagram of refrigerating.Evaporating film (25) and heat conducting film (37) coincide together.Heat conducting film (37) by thermal conductivity preferably anti-corrosion material make, can be metal, also can be with nonmetal.Air-flow was divided into 2 gangs of a and b after natural air entered the compartment evaporimeter, a is in evaporating film (25) absorption refrigeration on every side, make evaporating film keep isothermal evaporation, b then warm spot b' such as is condensed to by heat conducting film (37), a' is after flow deflector (34) turns to, flow out exhaust outlet (33), and row is to outdoor wall (36) left side.And b' is after warm spot such as being condensed to, forced to be pressed into kestner long-tube evaporator (8) by electric fan, though enthalpy reduces because b' is condensed, containing the temperature amount does not increase, so still be in the unsaturation attitude, still have bigger absorption energy, enter after membrane type refrigeration steamed device, absorption refrigeration to the cloud point temperature or the b of cloud point temperature ", and transfer to indoor wall (36) right side; as refrigerant gas b " utilized the absorption energy of air fully, and the water capacity increase of itself is seldom.Though coefficient of refrigerating performance decreases to cop=30～150 than one-level membrane type coefficient of refrigerating performance, a kind of even more ideal air-refrigerating conditioning machine.

The compartment refrigeration also can be made into bundled tube, sees Fig. 7 bundled tube schematic diagram of refrigerating at interval, and spray pipe (13) and equal water jacket (16) place the top of tube bank (39), and wetting evaporating film (25) is rolled in the outside of tube bank (29), makes the outer saturation region that forms of tube bank.When a flow through, evaporating film (25) was in the isothermal evaporation point, and tube bank is the heat conduction light wall pipe, has thermal conductivity preferably, and the b air-flow that flows through can be by condensation rapidly in tube bank, a is vertical with b moves.

Though one-level membrane type refrigeration coefficient of refrigerating performance is higher, wait warm spot higher, and the cold wind output temperature is higher, can only be applicable to dry area and the less demanding user of refrigeration.And secondary Air regulation refrigeration principle has the lower warm spot that waits, and output cold wind water capacity increases less.The exhausted most area of China all can obtain satisfied result of use.

This refrigeration principle also can be applicable to the condenser isothermal refrigeration of mechanical refrigerator.See schematic diagram Fig. 7.Special flat condenser pipe (38), the outside are evaporating film (25) and saturation region (26), and the mechanical refrigeration agent working medium in the condenser pipe (38) can be forced to be condensed to wet-bulb temperature or below the cloud point temperature, and reduces condensation temperature greatly.This mechanical refrigeration coefficient can improve greatly, as be applied to central air conditioning then energy-saving effect be tangible.
