The specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is a part of embodiment of the present invention, rather than whole embodiment.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skills obtain under the prerequisite of not making creative work, should belong to the scope of protection of the invention.
Fig. 1 shows the schematic side elevation of air-conditioner 100 according to an embodiment of the invention.
As shown in Figure 1, the air-conditioner 100 of the embodiment of the present invention comprises: heat exchanger 110, comprises the first district 110a and Second Region 110b; At least one first blower fan 120, is arranged on the position corresponding to the first district 110a; At least one second blower fan 130, is arranged on the position corresponding to Second Region 110b; Controller 140, be arranged to when meeting dehumidifying condition, controlling the first blower fan 120 moves with the first rotating speed, so that the first district 110a dehumidifies to the air of the first district 110a that flows through, and regulate the second rotating speed of the second blower fan 130, to regulate the refrigerating capacity of Second Region 110b output, wherein this second rotating speed is greater than this first rotating speed.
In embodiments of the present invention, heat exchanger 110 is an entirety, and inside is not distinguished, and for convenience of description, heat exchanger 110 is divided into the first district 110a and Second Region 110b, to correspond respectively at least one first blower fan 120 and at least one second blower fan 130.Should be understood that the first district 110a can refer to the arbitrary district in multiple dehumidifying district, Second Region 110b can refer to the arbitrary district in multiple refrigeration areas, corresponding at least one first blower fan 120 in each dehumidifying district, corresponding at least one second blower fan 130 of each refrigeration area.Heat exchanger 110 is for carrying out exchange heat with the surperficial air of flowing through, and can determine according to refrigeration demand the flow of cold-producing medium, for example, frequency-changeable compressor (or freezing water valve) can regulate automatically according to refrigeration demand the flow of cold-producing medium, thereby regulates the output of refrigerating capacity.
In an embodiment of the present invention, controller 100 can be controlled the first blower fan 120 and move with the first rotating speed under dehumidification mode, and regulates the second rotating speed of the second blower fan 130, thereby realizes dehumidifying and refrigeration simultaneously; Controller 100 can also regulate the first blower fan 120 and the second blower fan 130 to move with the second rotating speed under refrigeration mode, thus the refrigeration of realization.
Take transducer air conditioning as example, air-conditioner 100 can adopt falling temperature method dehumidifying.While freezing due to air-conditioner 100, the temperature of heat exchanger 110 is under dew-point temperature, therefore, under dehumidification mode, for example, when controller 140 with the first lower rotating speed (can be controlled at least one first blower fan 120, compared with fan speed during with refrigeration mode) when operation, air is with flow through the first district 110a of heat exchanger 110 of flow velocity very slowly, airborne steam can be condensate on the first district 110a of heat exchanger 110, reach the object of dehumidifying, now, at least one second blower fan 130 pumps to Second Region 110b ambient air with the second rotating speed the outside of air-conditioner 100, controller 140 can regulate this second rotating speed to carry out the refrigerating capacity of regulation output, to reach the object of refrigeration.
Therefore, the air-conditioner of the embodiment of the present invention, by blower fan grouping is controlled, a part of blower fan can be moved with the rotating speed of presetting, so that the part that on heat exchanger, this part blower fan is corresponding is to air dewetting, and another part blower fan can be according to refrigeration demand adjusting rotary speed, so that the refrigerating capacity of regulation output when air is dehumidified, thereby the temperature of air-conditioner surrounding environment fluctuates while avoiding dehumidifying, further avoided affecting due to temperature fluctuation the normal operation of the equipment of surrounding environment.
In addition, in conventional dehumidifying technology, the temperature fluctuation causing for fear of dehumidifying, can increase electric heating equipment and carry out temperature-compensating, and according to embodiments of the invention, while entering dehumidification mode, dehumidifying is parallel with refrigeration, therefore, can not cause fluctuation to the temperature of machine room, do not need to increase electric heating equipment, reduced equipment cost and operating cost, reduced the risk of device failure simultaneously.
In embodiments of the present invention, air-conditioner 100 can be chilled water air-conditioner, can be also transducer air conditioning, can also be air-conditioner with fixed frequency, and the embodiment of the present invention does not limit this.
In an embodiment of the present invention, when meeting dehumidifying condition, air-conditioner 100 can enter dehumidification mode.According to the difference of air-conditioning type, dehumidification mode can be different.For example, for the air-conditioning of any kind (for example, transducer air conditioning or air-conditioner with fixed frequency), under dehumidification mode, controller can be controlled the first blower fan 120 and move with the first rotating speed, regulates the second rotating speed of the second blower fan 130 simultaneously, and for transducer air conditioning, under dehumidification mode, controller can also carry out by the flow of the cold-producing medium of adjusting heat exchanger the refrigerating capacity of regulation output, and embodiments of the invention are not construed as limiting this.Should be understood that above-mentioned the second rotating speed can fix, also can change.
Particularly, in embodiments of the present invention, when air-conditioner 100 is transducer air conditioning or chilled water air-conditioner, controller 140 is also controlled the flow of cold-producing medium in heat exchanger, the refrigerating capacity of regulation output.Refrigerant flow decides according to refrigeration demand, and this refrigeration demand can determine according to the temperature difference between the return air temperature of air-conditioner and return air set point temperatures.When this temperature difference is timing, refrigeration demand has been described, compressor raising frequency or freezing water valve leave greatly, and refrigerant flow is increased; When the temperature difference is negative value, illustrate that now, without refrigeration demand, compressor frequency reducing or freezing water valve turn down, refrigerant flow is reduced; The temperature difference is zero, and the duty of compressor and freezing water valve remains unchanged, and refrigerant flow is constant.Alternately, as another embodiment, this refrigeration demand can also decide according to the temperature difference between the wind pushing temperature of air-conditioner and air-supply set point temperatures.
For chilled water air-conditioning, traditional dehumidification mode relies on higher to the temperature of chilled water.When inflow temperature higher (approaching environment dew-point temperature), effect on moisture extraction can be very poor, and under the dehumidification mode of embodiments of the invention, as long as inflow temperature is lower than environment dew-point temperature, for example, by the flow through wind speed (, lower than the wind speed in when refrigeration) of heat exchanger surface of reduction, can improve equally effect on moisture extraction, and the in the situation that of very low velocity, can reach very high effect on moisture extraction.
Alternatively, in embodiments of the present invention, air-conditioner 100 can be the capable level air-conditioner of multi fan.The capable level air-conditioner of this multi fan can be mainly used in data center machine room.Embodiments of the invention be not limited to this, air-conditioner 100 can be also other air-conditioning equipment that comprises multiple blower fans.
In embodiments of the present invention, as shown in Figure 1, the first blower fan 120 is arranged on the below of the second blower fan 130.Owing to can producing a large amount of condensed waters on the first district 110a surface of heat exchanger in dehumidification process, and the air quantity of Second Region 110b is larger, if Second Region 110b is positioned at the first district 110a below, heat exchanger surface may blow off condensed water, therefore, the first district 110a is arranged on to Second Region 110b below, can avoids condensed water to blow off heat exchanger surface and the adverse consequences that causes.
For convenience, Fig. 1 only illustrates the dividing mode of a kind of the firstth district and Second Region and the dividing mode of the first blower fan and the second blower fan, it will be understood by those skilled in the art that other dividing mode is all in protection scope of the present invention.
Should be understood that air-conditioner can comprise shell, each part of above-mentioned air-conditioner can be contained in this shell.Embodiments of the invention are not limited to this, and for example, above-mentioned air-conditioner also can be without shell, but is directly installed in the frame of data center machine room.
Fig. 2 is the schematic side elevation of air-conditioner 200 according to another embodiment of the present invention.The air-conditioner 200 of Fig. 2 is examples of the air-conditioner 100 of Fig. 1.
Particularly, as shown in Figure 2, air-conditioner 200 also comprises: baffle plate 150, be arranged between the first space and second space, for this first space and this second space are separated, wherein, this first space is the space between at least one first blower fan 120 and the first district 110a, and this second space is the space between at least one second blower fan 130 and Second Region 110b.
In other words, one end of baffle plate 150 can be arranged between the first blower fan 120 and the second blower fan 130, and the other end of baffle plate 150 can be arranged between the first district 110a and Second Region 110b.When entering dehumidification mode, because the wind speed of the first blower fan 120 and the second blower fan 130 is different or air quantity inequality, baffle plate 150 is set between this first space and this second space and can prevents the wind-fall stream or the interior circulation that due to wind speed difference or air quantity inequality, cause, thereby avoid affecting effect on moisture extraction.
Fig. 3 is the schematic side elevation of air-conditioner 300 according to another embodiment of the present invention.Fig. 3 is the example of Fig. 1.The air-conditioner 300 of Fig. 3 is examples of the air-conditioner of Fig. 1 and 2.
Particularly, as shown in Figure 3, air-conditioner 300 also comprises: temperature sensor 160, be arranged between at least one second blower fan 130 and the Second Region 110b of heat exchanger, for measuring the temperature of the air between at least one second blower fan 130 and Second Region 110b, wherein, controller 140 is arranged to according to the second rotating speed of at least one the second blower fan 130 of this temperature control, to regulate the refrigerating capacity of this Second Region 110b output.
This temperature that temperature sensor 160 detects is commonly referred to wind pushing temperature, when entering dehumidification mode, because the rotation speed of the fan of at least one the first blower fan 120 is very low, cause the leaving air temp of air-conditioning very low, now at least one the first blower fan 120 of air-conditioner 300 and the leaving air temp inequality of at least one the second blower fan 130, so the temperature computation refrigeration demand that now a serviceability temperature sensor 160 is measured.Controller 140 is arranged to according to the second rotating speed of at least one the second blower fan 130 of this temperature control, be specially controller 140 according to the second rotating speed of at least one the second blower fan 130 of the temperature difference control between this return air temperature and wind pushing temperature, specific implementation is: this temperature difference is larger, illustrate that now refrigerating capacity demand is larger, now the second rotating speed is just larger, and the output of blower fan is just larger; Return air and the air-out temperature difference are less, illustrate that now refrigerating capacity demand is less, and now the second rotating speed is less, and blower fan output is just less.
Fig. 4 is the schematic side elevation of air-conditioner 400 according to another embodiment of the present invention.Fig. 4 is the example of the air-conditioner of Fig. 1 to 3.
Alternatively, in embodiments of the present invention, as shown in Figure 4, this air-conditioner 400 also comprises: Temperature Humidity Sensor 170, for measuring the humidity of air, wherein, this satisfied dehumidifying condition comprises: this humidity is greater than the first setting value.The humidity of above-mentioned air can be the relative humidity of air.
Particularly, in embodiments of the present invention, this first setting value is what according to the working environment of air-conditioner 100, the specific requirement of humidity is arranged, and this first setting value can guarantee the normal operation of equipment in this working environment.For example, in the application scenarios of data center machine room, require humidity between 40%～60%, when the humidity of air exceeds 60%, may affect the normal operation of equipment in machine room, therefore this first setting value can not be greater than 60%, and it is 55% that this first setting value for example can be set, and enters the dehumidification mode of air-conditioner when humidity is greater than 55%, be a part of blower fan to move air dewetting compared with the slow-speed of revolution, another part blower fan continues according to the refrigerating capacity of refrigeration demand regulation output; For another example, this first setting value can not arrange too low, if for example the first setting value is set to 45%, when humidity is greater than 45%, air-conditioner 100 enters dehumidification mode, may cause like this air-conditioner frequently to dehumidify, make energy consumption higher, therefore, can to machine room, not dehumidify in this case, but the embodiment of the present invention is not limited to this.
Alternately, as another embodiment, this satisfied dehumidifying condition can be that the humidity of the air that receives of the miscellaneous equipment (for example, pass through network) of controller 140 from air-conditioner is greater than the first setting value.
Alternately, as another embodiment, this satisfied dehumidifying condition can be that controller 140 receives and is used to indicate the instruction that enters dehumidification mode, this controller 140 moves with the first rotating speed according at least one first blower fan 120 of this instruction control receiving, and regulates the second rotating speed of at least one the second blower fan 130.For example, can be according to special requirement, manually force air-conditioner to enter dehumidification mode.In the situation that air-conditioner is networked, can also enter from Network Capture the instruction of dehumidification mode, for example, can be unified by network the humidity of testing environment, and control multiple air-conditioners and combine dehumidifying, like this, not only can avoid, into each air-conditioner, Temperature Humidity Sensor is installed, reduce cost, and made whole machine room humidity even.
Alternatively, in embodiments of the present invention, controller 140 is also arranged to be down to while being equal to or less than this first setting value from being greater than this first setting value when the humidity of air, and the rotating speed of at least one the first blower fan 120 is increased to this second rotating speed from this first rotating speed.
Particularly, in embodiments of the present invention, controller 140 is also arranged to, according to the step-length of setting, the rotating speed of the first blower fan 120 is progressively increased to this second rotating speed from this first rotating speed.
When the humidity of air, from being greater than this first setting value, be down to while being equal to or less than this first setting value, improve the rotating speed of at least one the first blower fan 120, make it exit dehumidification mode.Due to the first surface, district of the heat exchanger of at least one the first blower fan 120 correspondence more condensed water that can condense, rotation speed of fan is opened suddenly greatly, the unexpected increase of air quantity may blow out heat exchanger by the condensed water condensing due to dehumidifying on heat exchanger, produces adverse consequences.Therefore for avoiding blower fan to open suddenly greatly, maximum step-length can be set, according to the speed-raising process of this at least one the first blower fan 120 of maximum step-length control, make the rotating speed rising from low to high of at least one the first blower fan 120.When the rotating speed of at least one the first blower fan 120 is with at least one second blower fan 130 rotating speed when consistent, at least one first blower fan 120 and at least one second blower fan 130 are all according to refrigeration demand adjusting rotary speed, and air-conditioner 100 thoroughly exits dehumidification mode.
Alternatively, in embodiments of the present invention, air-conditioner 100 can also comprise that the second temperature sensor 180, the second temperature sensors 180 are arranged between at least one first blower fan 120 and this firstth district 110a.When air-conditioner 100 exits after dehumidification mode, controller 140 is also arranged at least one first blower fan 120 of temperature control of measuring according to temperature sensor 160 and this second temperature sensor 180 and the rotating speed of at least one the second blower fan 130, the refrigerating capacity of regulation output.
When operation of air conditioner is under refrigeration mode, rotation speed of fan unification is by one group of signal controlling, the rotating speed of all blower fans is consistent, the temperature that now temperature sensor 160 is measured with the second temperature sensor 180 should be consistent, so this Time Controller 140 is arranged to the rotating speed of the mean temperature control blower fan of the temperature of measuring according to temperature sensor 160 and this second temperature sensor 180.
In embodiments of the present invention, when humidity is higher, Second Region 110b is when flowing through the air heat exchange of Second Region 110b, and airborne part steam also can be condensate on heat exchanger, and Second Region 110b also can play the effect of dehumidifying in refrigeration.Therefore,, regardless of ambient humidity, the air-conditioner 100 of the embodiment of the present invention all can be flexibly, dehumidify efficiently.
Alternatively, in embodiments of the present invention, when controller 140 can also be arranged in refrigeration demand and is greater than default threshold value, be prohibited from entering dehumidification mode.
In other words, when the humidity of air is greater than this first setting value, and when the refrigeration demand of current air-conditioner surrounding environment is greater than default threshold value, to air running refrigerating, be now top priority, controller 140 can be arranged to not allow air-conditioner 100 to enter dehumidification mode.This is the refrigerating capacity that can affect air-conditioner 100 owing to entering dehumidification mode.When the air themperature of surrounding environment reduces,, when this refrigeration demand is equal to or less than default threshold value, controller 140 can be controlled at least one first blower fan 120 and move with the first rotating speed, enters dehumidification mode.
Should be understood that Fig. 1 to Fig. 4 shows heat exchanger 110 and the first blower fan 120 and the second blower fan 130 and vertically places.Alternatively, heat exchanger 110 and the first blower fan 120 and the second blower fan 130 can also horizontal positioned.Concrete modes of emplacement can need to determine according to concrete installation environment.Alternatively, the first blower fan 120 and the second blower fan 130 can also be divided into two row and be set up in parallel the offside at heat exchanger 110, as shown in Figure 5.
Fig. 5 is the schematic plan of air-conditioner 500 according to another embodiment of the present invention.The air-conditioner 500 of Fig. 5 is examples of the air-conditioner 100 of Fig. 1.Air-conditioner 500 comprises: heat exchanger 510, at least one first blower fan 520, at least one the second blower fan 530 and controller 540, similar with heat exchanger 110, at least one first blower fan 120, at least one second blower fan 130 and the controller 140 of the air-conditioner 100 of Fig. 1, do not repeat them here.
Be illustrated in figure 5 the first blower fan 520 and the second blower fan 530 is set up in parallel the schematic plan at heat exchanger 510 offsides, the baffle plate 560 arranging in the middle of second space between the first space and the second blower fan 530 and the Second Region 510b between the first blower fan 520 and the first district 510a, can prevent that the air in the first space and second space from flowing backwards, and avoids affecting effect on moisture extraction.
Therefore, the air-conditioner of the embodiment of the present invention, by blower fan grouping is controlled, a part of blower fan can be moved with the rotating speed of presetting, so that the part that on heat exchanger, this part blower fan is corresponding is to air dewetting, and another part blower fan can be according to refrigeration demand adjusting rotary speed, so that the refrigerating capacity of regulation output when air is dehumidified, thereby the temperature of air-conditioner surrounding environment fluctuates while avoiding dehumidifying, further avoided affecting due to temperature fluctuation the normal operation of the equipment of surrounding environment.
For convenience; in Fig. 5, only show row first blower fan and row second blower fan that are arranged in juxtaposition; what it will be understood by those skilled in the art that is; can be arranged in juxtaposition multiple row the first blower fan and/or multiple row the second blower fan, within the first blower fan that multiple row is arranged and/or the scheme of the second blower fan all fall into the protection domain of embodiments of the invention.
Above, in conjunction with Fig. 1 to Fig. 5, describe the air-conditioner according to the embodiment of the present invention in detail, the following describes according to the control method of the dehumidifying of the embodiment of the present invention.
Fig. 6 shows according to the indicative flowchart of the control method 600 of the dehumidifying of the embodiment of the present invention.As Fig. 6 should show, the method is carried out by the controller of air-conditioner, and control method 600 comprises following content.
610, when meeting dehumidifying condition, control at least one first blower fan and move with the first rotating speed, so that the firstth district on heat exchanger corresponding to this at least one the first blower fan dehumidifies to the air in this firstth district that flows through.
