Description
Technical field
The present invention relates to the cold and hot switching technology of air-conditioning, particularly a kind of air-cooled coil pipe of air-conditioning heat pump use.
Background technology
At present, the air-cooled heat pump type air-conditioner is a kind of air conditioner that often uses, and it is widely used in the indoor environments such as family, office.Air-conditioning refrigeration system is operated in hot environment and the low temperature environment, in its cooling cycle system, by circulating of cold-producing medium heat in the low temperature environment is discharged in the hot environment.In the heat pump circulating system of air-cooled heat pump type air-conditioner, by circulating of cold-producing medium the low-grade heat in the low temperature environment and input power together are converted into high-grade heat, and it is discharged in the hot environment.
Figure 1A is the structure chart of air-cooled heat pump unit of the air-cooled heat pump type air-conditioner of prior art.Shown in Figure 1A, wherein, the air-cooled heat pump unit of air-cooled heat pump type air-conditioner is mainly by oil-to-water heat exchanger 101 and air-cooled heat exchanger.This air-cooled heat exchanger comprises air-cooled coil pipe 102a～102d.Heat pump also comprises compressor 103 and throttle mechanism 104a and 104b.When cooling system moved, compressor 103 sucked the low-temp low-pressure gaseous refrigerant that heat exchanger 101 is discharged by air intake duct 105 and four-way change-over valve 106, and it is compressed into the overheated gaseous refrigerant of HTHP.The gaseous refrigerant of the HTHP after the compression is successively by behind exhaust angle valve 107, gas exhaust piping 108 and the four-way change-over valve 106, enters among air-cooled coil pipe 102a～102d and the outside air heat exchange, makes it be condensed into the liquid refrigerant of high pressure.Condensed high pressure liquid refrigerant is corresponding successively by behind shunt head 109a～109d, check valve 110 and the device for drying and filtering 111, carries out reducing pressure by regulating flow by throttle mechanism (refrigeration expansion valve) 104a again.Gas-liquid two-phase mix refrigerant behind reducing pressure by regulating flow enters heat exchanger 101 and chilled water heat exchange, be evaporated to the gaseous refrigerant of low pressure behind the heat of cold-producing medium absorption refrigerating water, the gaseous state low pressure refrigerant returns compressor 103 by four-way change-over valve 106 and air intake duct 105 successively.So just finish a kind of refrigeration cycle, and correspondingly entered next kind of refrigeration cycle.
When system's heating operation, compressor 103 sucks the low-temp low-pressure gaseous refrigerant that air-cooled coil pipe 102a～102d discharges by air intake duct 105, and corresponding it is compressed into the overheated gaseous refrigerant of HTHP.High temperature and high pressure gaseous refrigerant after the compression is successively by exhaust angle valve 107, gas exhaust piping 108 and four-way change-over valve 106, be drained in the heat exchanger 101, these high temperature and high pressure gaseous refrigerants in heat exchanger 101 with the hot water heat exchange, gaseous refrigerant is condensed into liquid state and discharges latent heat.After the liquid refrigerant of high pressure leaves heat exchanger 101, successively by behind reservoir 112, check valve 113 and the device for drying and filtering 111, enter throttle mechanism 104b and carry out throttling, liquid refrigerant becomes the gas-liquid two-phase mix refrigerant of low pressure after throttle mechanism 104b throttling.This gas-liquid two-phase cold-producing medium is by flowing into each air-cooled coil pipe 102a～102d after shunt head 109a～109d mean allocation, the corresponding heat that is evaporated to low-pressure gaseous refrigerant and absorbs surrounding environment in each air-cooled coil pipe 102a～102d, the gaseous refrigerant after the evaporation is got back to compressor 103 by four-way change-over valve 106 and air intake duct 105 successively.So just finished one and heated circulation, and the corresponding next one that enters heats circulation.
And in the winter time, air-cooled heat pump unit is when carrying out heating operation, and the air of certain humidity is cooled near air-cooled coil pipe 102a～102d.When environment temperature is lower, namely air-cooled coil pipe 102a～when the 102d surface temperature was lower than the air dew point temperature, condensation can appear in its fin surface.And when the fin temperature was lower than 0 ℃, these condensations can be solidified into frost.Because the formation of frost and increasing gradually can ventilate that area is corresponding to be reduced, corresponding air flow resistance and the heat transfer resistance of having increased.Along with the increase of frost thickness, the heat transfer efficiency of heat exchanger 101 also has substantial degradation simultaneously, when serious heat exchanger channels is blocked fully, thereby heat pump can't be worked.Heat pump cycle and heating capacity in order effectively to keep air-cooled heat pump must periodically defrost.
Generally by the realization that turns to of four-way change-over valve 106, namely when generator set controller judged that current running status satisfies the defrosting condition, four-way change-over valve 106 outage commutations changed refrigerating operaton into to air-conditioner defrosting.The high temperature and high pressure gaseous refrigerant that compressor 103 is discharged makes it the frost layer of thermal release to the fin surface of air-cooled coil pipe 102a～102d heat absorption and melts.For taking full advantage of condensation heat, blower fan 114a and 114b shut down during the defrosting.
Figure 1B is the structure chart of the air-cooled coil pipe of prior art.Shown in Figure 1A and Figure 1B, wherein, air-cooled coil pipe 102a～102d comprises the heat exchange copper tube 115 of a plurality of circuitous settings.More clear simple and clear for the structure that makes air-cooled coil pipe 102a～102d, only draw the structure that several heat exchange copper tubes 115 are showed air-cooled coil pipe 102a～102d better among Figure 1B.A-quadrant shown in Figure 1B wherein, is equipped with fin 116 for showing the perspective enlarged drawing of the annexation between heat exchange copper tube 113 and the fin 116 between the heat exchange copper tube 115,116 of fins make and connect between the heat exchange copper tube 115 and UNICOM not.These heat exchange copper tubes 115 and fin 116 are by carrying out heat exchange with the outside air convection current.The two ends of air-cooled coil pipe 102a～102d are equipped with on the first baffle plate 117, the first baffle plates 117 for fixing heat exchange copper tube 115 and are provided with the first through hole, and heat exchange copper tube 115 is fixed by passing the first through hole.
Because the height of the air-cooled coil pipe 102a of air-cooled heat pump type air-conditioner～102d in the vertical direction (parallel directions of two the first baffle plates 117) is higher, in the winter time during heating and defrosting, defrosting water need to flow to the bottom of air-cooled coil pipe 102a～102d downwards, and flow out the required time of air-cooled coil pipe 102a～102d from the bottom longer.In addition, the heat of air-cooled coil pipe 102a～102d bottom also can be absorbed by the defrosting water that gravitate flows from top to bottom, thereby causes the waste of heat.And when outdoor environment is lower than 0 ℃,, and stockpile when air-cooled coil pipe 102a～102d bottom owing to be not able to do in time to discharge fully or fully evaporation at the defrosting water of air-cooled coil pipe 102a～102d bottom.If this moment, air-cooled heat pump unit was converted to heating operation, can cause the defrosting water that air-cooled coil pipe 102a～the 102d bottom stockpiles before discharging air-cooled coil pipe 102a～102d, to freeze rapidly.And defrosting water stockpiles in the bottom of air-cooled coil pipe 102a～102d and icing process is the process of a reciprocation cycle, and the time one is long, and the ice that air-cooled coil pipe 102a～102d bottom is formed by defrosting water covers.On this position, liquid refrigerant in the heat exchange copper tube 115 can't with air heat-exchange, after flowing through this part liquid refrigerant and the gaseous refrigerant of other branch roads mixing, the degree of superheat of evaporator outlet is reduced, and throttle mechanism 104a and 104b are turned down, and then the pressure of inspiration(Pi) of compressor 103 is further descended, thereby affect the performance of whole air-cooled coil pipe 102a～102d.Can make the frequent defrost of air-cooled heat pump unit of air-cooled heat pump type air-conditioner when serious, thereby reduce the life-span of the compressor 103 of air-conditioner.
Therefore, how to prevent that defrosting water is in the icing problem demanding prompt solution that just becomes in air-cooled coil pipe bottom.

In order thoroughly to understand the present invention, detailed step will be proposed, so that how explanation the present invention solves the problem that defrosting water freezes in air-cooled coil pipe bottom in following description.Obviously, execution of the present invention is not limited to the specific details that the technical staff of air-conditioning cold technical field of heat exchange has the knack of.Preferred embodiment of the present invention is described in detail as follows, yet except these were described in detail, the present invention can also have other embodiments.
Fig. 2 A is the structure chart of the heat exchanger for air-conditioning heat pump according to an embodiment of the invention, Fig. 2 B is the partial enlarged drawing of the a-quadrant shown in Fig. 2 A of the heat exchanger for air-conditioning heat pump according to an embodiment of the invention, and Fig. 2 C is the partial enlarged drawing in the B zone shown in Fig. 2 A of the heat exchanger for air-conditioning heat pump according to an embodiment of the invention.Shown in Figure 1A, Figure 1B, Fig. 2 A, Fig. 2 B and Fig. 2 C, the heat exchanger of present embodiment comprises air-cooled coil pipe 102a～102d more than, this air-cooled coil pipe 102a～102d comprises: heat exchange copper tube 115, fin 116 and baffle plate 117, heat exchange copper tube 115 circuitous settings, and interconnect by fin 116, be provided with through hole on the baffle plate 117, heat exchange copper tube 115 is fixed by passing through hole.The air-cooled coil pipe 102a～102d of present embodiment also comprises: at least one water fender 210, the two ends of water fender 210 are corresponding to be fixedly connected with baffle plate 117.Need to prove, for the structure to the air-cooled coil pipe 102a～102d of present embodiment is illustrated more clearly in, in Fig. 2 A, Fig. 2 B and Fig. 2 C, do not draw heat exchange copper tube 115 and fin 116.The two ends of water fender 210 are corresponding can be the welding manner that those skilled in the art commonly use with the mode that is fixedly connected with of baffle plate 117.
The defrosting water gravitate that water fender 210 tops produce is in the process of heat exchange copper tube 115 and fin 116 trickling downwards, can stockpile first on water fender 210, and discharge air-cooled coil pipe 102a～102d by water fender 210 from baffle plate 117, compared to existing technology, after increasing water fender 210, the trickling distance of defrosting water in air-cooled coil pipe 102a～102d had larger reducing (not needing to flow through the distance of water fender 210 bottom air-cooled coil pipe 102a～102d along heat exchange copper tube 115 and fin 116).So also reduced the chance that defrosting water stockpiles and freezes in air-cooled coil pipe bottom with regard to corresponding, one side can shorten the defrost time effectively, can effectively promote on the other hand the performance of the air-cooled heat pump unit of air-cooled heat pump type air-conditioner.All right energy savings reduces the loss of air-conditioner, prolongs its service life.
For further reducing the trickling distance of defrosting water in air-cooled coil pipe 102a～102d, can two or more water fenders 210 of parallel installation, these water fenders 210 can correspondingly be divided into some zones with air-cooled coil pipe 102a～102d in the vertical direction, thus the corresponding trickling distance of defrosting water in air-cooled coil pipe 102a～102d that reduce effectively.Wherein, when these water fenders 210 are corresponding when air-cooled coil pipe 102a～102d is divided into some zones, reduce the best results of the trickling distance of defrosting water in air-cooled coil pipe 102a～102d.
Air-cooled coil pipe 102a～102d can also comprise at least 3 baffle plates 117, on the basis of two baffle plates 117 at the two ends of the air-cooled coil pipe 102a～102d of being correspondingly positioned at of prior art, increase at least one baffle plate 117 on 117 on these two baffle plates, and make between whole baffle plate 117 and be parallel to each other.Need to prove, without essential distinction, can be duplicate structure between each baffle plate 117, and its effect all is for supporting stability and the intensity of heat exchanger to strengthen its structure.Wherein, consider to make the easier for installation quick of water fender 210 that effect is better when the spacing of each baffle plate 117 equates.
Comprise in the situation of at least 3 baffle plates 117 at air-cooled coil pipe 102a～102d, water fender 210 is installed between two adjacent baffle plates 117, the one end is connected with any baffle plate 117, the other end is connected with another baffle plate 117 nearest apart from this baffle plate 117, be provided with through hole on the baffle plate 117, heat exchange copper tube 115 is fixed by passing through hole.By increasing at least one baffle plate 117, can increase on the one hand the intensity of the structure of whole air-cooled coil pipe 102a～102d, can also make on the other hand defrosting water along baffle plate 117 to the bottom downstream to ventilated disc pipe 102a～102d, and discharge fast air-cooled coil pipe 102a～102d from the bottom.Can further reduce like this trickling distance of defrosting water in air-cooled coil pipe 102a～102d.
For guaranteeing that further defrosting water discharges the efficient of air-cooled coil pipe 102a～102d, the number b of the number a of water fender 210 and baffle plate 117 should satisfy following relation:
a≥b-1
If the number of water fender 210 less than b-1, then can cause having at least two baffle plates 117 and water fender 210 is not installed.Therefore, for reaching technique effect of the present invention, need to make the number a of water fender 210 satisfy a 〉=b-1.For making defrosting water be flow to as early as possible the bottom of air-cooled coil pipe 102a～102d by water fender 210, and discharge from its bottom.The angle that water fender 210 and heat exchange copper tube are 115 is that 0 degree is to 10 degree.Like this under action of gravitation, owing to the inclination of water fender, at the vector component that can produce a downward gravity along the installation direction of water fender 210.Thereby can accelerate the flow velocity of defrosting water, and then effectively shorten defrosting water and stockpile time in air-cooled coil pipe 102a～102d.Because the angle that water fender 210 and heat exchange copper tube are 115 is larger, the flow velocity of defrosting water is just faster, therefore, and when the angle of 115 of water fender 210 and heat exchange copper tubes is that 6 to spend when spending to 10 effect better.The angle of considering simultaneously 115 of water fender 210 and heat exchange copper tubes can not be excessive, otherwise can affect the quantity of heat exchange copper tube 115, thereby reduce heat exchange efficiency.Therefore, the angle that water fender 210 and heat exchange copper tube are 115 is that 4 degree to 6 degree are the better flow velocity that can effectively accelerate defrosting water, the again unlikely angle value that affects the quantity of heat exchange copper tube 115.
Fig. 2 D is the structure chart of the water fender of the heat exchanger that is used for air-conditioning heat pump according to a preferred embodiment of the present invention.Shown in Fig. 2 D, the water fender 210 of this preferred embodiment has dash along 211 and/or drips along 212 in the direction parallel with heat exchange copper tube 115, dash is positioned at the close blower fan 114a of air-cooled coil pipe 102a～102d and the side of 114b along 211, and dripping is positioned at opposite side along 212.
The width of this water fender 210 can less than the thickness of whole heat exchanger, also can be equal to or greater than the thickness of heat exchanger.With regard to technique effect, it is better that the width of water fender 210 is equal to or greater than the technique effect of thickness of heat exchanger.
Fig. 2 E is the side view of the water fender of the heat exchanger that is used for air-conditioning heat pump according to a preferred embodiment of the present invention.Shown in Fig. 2 E, dash has been installed has effectively been collected the defrosting water that is dripped by its top along 211 water fender 210.The dash of water fender 210 is α along the plane at 211 places and the interplanar angle at water fender 210 places, and α can be that acute angle also can be right angle or obtuse angle, and the concrete angle value of α can be selected according to the actual conditions of the working environment of air-conditioning by the technical staff.When the defrosting water that produces in the actual working environment of air-conditioning was more, α was preferably the obtuse angle, can collect better defrosting water like this.When the defrosting water that produces in the actual working environment of air-conditioning was less, α was that acute angle just can meet the demands.Like this, defrosting water can very successfully drip from water fender 210, directly drips to the bottom of air-cooled coil pipe 102a～102d, and flows out from the bottom of air-cooled coil pipe 102a～102d.So just effectively reduced trickling distance and the trickling time of defrosting water in air-cooled coil pipe 102a～102d.
Dripping of water fender 210 can be acute angle or right angle along the plane at 212 places and the interplanar angle β at water fender 210 places.For preventing being fallen on the heat exchange copper tube 115 and fin 116 of air-cooled coil pipe 102a～102d by the defrosting water that water fender 210 drips, thereby make water fender 210 ineffective.Drip along can installing in a manner described, so just can guarantee that defrosting water can be directly splashes into bottom air-cooled coil pipe 102a～102d ground by dripping along 212, and from the bottom outflow of air-cooled coil pipe 102a～102d.The trickling distance of defrosting water in air-cooled coil pipe 102a～102d and the technique effect of trickling time have so just effectively been guaranteed to reduce.When to drip along the interplanar angle β at the plane at 212 places and water fender 210 places be 10 degree to the acute angle of 30 degree, technique effect was better.When being the acute angle of 15 degree when dripping along the interplanar angle β at the plane at 212 places and water fender 210 places, technique effect is best.
