The specific embodiment
Describe the present invention in detail below in conjunction with accompanying drawing.
Fig. 1 represents the schematic cross-section of the indoor set of the present invention's one routine pipe type air conditioner.Fig. 2 represents the schematic perspective view of major part of the indoor set of the present invention's one routine pipe type air conditioner shown in Figure 1.As Fig. 1 or shown in Figure 2, the indoor set of pipe type air conditioner of the present invention mainly comprises: shell 5, be arranged on the heat exchanger 4 of these shell 5 inside, a plurality of fans 1 that place the upstream side of heat exchanger 4, each fan 1 is all surrounded by the fan housing 6 of each blow-off outlet towards a side of heat exchanger, division board 2 is isolated fan 1 and heat exchanger 4, but the place between a plurality of fan 1 is provided with the motor 10 of drive fan 1.In addition, the blow-off outlet place of fan housing 6 is provided with rotating wind blade 7, and wind blade 7 is connected with wind blade drive unit 11, and wind blade 7 can be rotated by this wind blade drive unit 11.
In the present invention, the number of the wind blade 7 that is provided with at the blow-off outlet place of the fan housing 6 of each fan can be determined according to the specific embodiment, can a wind blade be set at each fan housing blow-off outlet, also can two or more wind blades be set at each fan housing blow-off outlet.
As a rule, two wind blades are set in the exit of each fan housing and can reach purpose of the present invention.For example, as shown in Figure 2.
In addition, the connected mode of wind blade 7 and wind blade drive unit 11 can determine according to the manner of execution of the number of wind blade 7 and required wind blade 7 or wind blade 7 locus with respect to the blow-off outlet of fan housing 6.The situation that two wind blades are set with the blow-off outlet place of the fan housing of each fan is an example, and wind blade 7 and the connected mode of wind blade drive unit 11 can be taked mode as shown in Figure 3.Specifically, the wind blade on the close right side of each fan is connected with the wind blade drive unit on right side, that is, the wind blade on the close right side of each fan is rotated by the wind blade drive unit on right side; The wind blade in the close left side of each fan is connected with the wind blade drive unit in left side, that is, the wind blade in the close left side of each fan is rotated by the wind blade drive unit in left side.
In addition, pipe type air conditioner of the present invention also possesses the controller of the action of above-mentioned wind blade drive unit of control and fan.Controller is controlled the wind blade drive unit according to the ruuning situation of concrete pipe type air conditioner and user's demand, and then the control wind blade is with respect to the locus of fan housing blow-off outlet.
In the pipe type air conditioner of the present invention, owing to be provided with rotating wind blade 7, can set the action of wind blade 7 and wind blade 7 locus according to different situations with respect to the fan housing blow-off outlet.And, air-supply can be directed on the optional position of heat exchanger 4 by this setting, thus, both can make heat exchanger 4 performance maximal efficiencies, can make the minimum efficient of heat exchanger 4 performances again.Further, can make the best efficient of heat exchanger performance, improve user's comfort according to user's requirement.
Describe the manner of execution of wind blade 7 and the locus that wind blade 7 is set with respect to the blow-off outlet of fan housing 6 below in detail.
In the pipe type air conditioner of the present invention, wind blade 7 can swing, and is for example, shown in Figure 4.Wind blade 7 will be blown and will be sent to equably on each zone of heat exchanger 4 this moment, can bring into play the efficient of heat exchanger well.
In addition, wind blade 7 also can be radial along air supply direction, shown in Fig. 2,3,5.And the radiation angle of wind blade 7 can be regulated according to the situation of air quantity.For example, increase the radiation angle along with the increase of air quantity, so that the propelling of air-supply reduces, brings into play effectively the efficient of heat exchanger.Wherein, so-called " radiation angle " is meant along the angle between the extended surface of two wind blades.Thus, wind blade 7 can make air-supply blow to equably on the heat exchanger 4, the subregion that has solved heat exchanger 4 in the conventional art well (for example, the two ends, the left and right sides of heat exchanger 4 and with the corresponding part of motor) can not wind-engaging problem, can bring into play the efficient of heat exchanger well.Specifically, because wind blade 7 of the present invention is connected with wind blade drive unit 11, wind blade 7 can change its locus with respect to the blow-off outlet of fan housing 6.For example, each wind blade 7 can be divided into third gear with respect to the locus of fan housing blow-off outlet: first grade, second grade, third gear, as shown in Figure 8.What represent among Fig. 8 is that the observer stands in the schematic diagram of 8 places, inlet scoop in the face of the wind blade of blow-off outlet 9 when overlooking, and wherein, is air supply direction from bottom to up.And the angle of among Fig. 8 first grade, second grade, third gear and air supply direction can change according to the design needs, further, also can as required establish several shelves more.This wind blade 7 can change according to the situation of air quantity with respect to the locus of the blow-off outlet of fan housing 6.For example, the situation that two wind blades are set with each fan is an example, and when air quantity was big, first wind blade of each fan used first grade, second wind blade use third gear (the radiation angle is bigger); When air quantity hour, first wind blade of each fan uses second grade, second wind blade to use second grade (the radiation angle is less); And when air quantity was moderate, first wind blade of each fan used first grade, second grade of second wind blade use (the radiation angle is moderate), or the like.Certainly, the position grouping method of first wind blade and second wind blade, the control method that promptly radiates angle is not limited only to above-mentioned several situation.
In heat exchanger 4, according to the difference of the flow direction of refrigerant, the size of the heat exchanger effectiveness of its zones of different is also different.For example, be example with the refrigerant direction among Fig. 9 and Figure 10, heat exchanger 4 has the inflow entrance and the flow export of refrigerant pipe simultaneously at the side on right side (also can be the side in left side), and wind blade to the left and right direction swing.In this case, it when turning round example with greenhouse, refrigerant is high temperature and high pressure gas near the inlet of refrigerant pipe, near the outlet of refrigerant pipe is high-pressure sub-cooled liquid, other parts are gas-liquid two-phase, and the heat exchange of refrigerant comprises sensible heat and latent heat two parts during the two-phase state, and therefore the two-phase side away from the inlet outlet is low relatively near the inlet of refrigerant pipe and the heat exchanger effectiveness of outlet side.For this reason, when air-conditioner start and through the certain hour preheating after, preferably wind blade is arranged to, air quantity is concentrated on avoid on the heat exchanger of side of heat exchanger of the inflow entrance that is provided with the refrigerant pipe and flow export.For example, the inflow entrance that is provided with the refrigerant pipe that heat exchanger is avoided in direction such as Figure 10 setting of wind blade and the side of flow export can help improving heat exchanger effectiveness, can bring into play the efficient of heat exchanger to greatest extent.That is to say, starting and that wind blade concentrates on air quantity to avoid on the heat exchanger of side of heat exchanger of the inflow entrance that is provided with the refrigerant pipe and flow export through after the certain hour.
In addition, in the pipe type air conditioner of the present invention, controller can be regulated the air quantity of fan interimly, the angle that can regulate wind blade and air supply direction by accessory drive simultaneously, thereby the air quantity of the described fan that the described wind blade of adjusting process blows out.Specifically, be used for the motor 11 of drive fan to use the alternating current motor usually, therefore, can only carry out interim adjusting for the air quantity of fan for the consideration on the cost, for example, air quantity can only be controlled at " height ", " in ", " low " Three Estate.And " height " and " in " between the control of size of air quantity, then can be undertaken by controller accessory drive, driving device controls wind blade.For example, if make wind blade become as shown in Figure 9, when closing the angle of fan housing blow-off outlet, air quantity is less; If make air blade become as shown in Figure 3 when air supply direction is radial, air quantity is bigger.
Below, the situation that two wind blades are set with each fan housing is an example, the action that specifies the wind blade of each period under cold-room/greenhouse working order with and with respect to the locus of fan housing blow-off outlet.
When cold-room turned round, controller made two wind blades to swing or to make it be radial along air supply direction, so that make the even wind-engaging of whole heat exchanger.
Under the greenhouse working order, when just starting, the temperature that blows out wind is lower, and therefore, controller is set at the air quantity of fan minimum, and, make wind blade be minimum air quantity position, for example, as shown in Figure 9.Among Fig. 9, wind blade is represented with vertical view.Thus, when making the time that heat exchange temperature rises rapidly, shortening heat starts, prevent that a large amount of cold wind is blown out to user's usage space.Through after the certain hour, the temperature that blows out wind is higher, therefore, can make wind blade be radial along air supply direction, for example, as shown in Figure 5, air quantity is blown on the heat exchanger equably, makes conditioned space reach the air-conditioning effect rapidly.Perhaps, when starting, make the air quantity of fan be set at minimum, wind blade and be minimum air quantity position, and air quantity is tilted with respect to air supply direction with predetermined angular through behind the certain hour, for example, as shown in figure 10.
In addition, in pipe type air conditioner of the present invention, no matter under the cold-room working order still under the greenhouse working order, also can start and make wind blade be radial along air supply direction through after the certain hour.
What is called in the above description " certain hour " is meant the time till the imperceptible cold wind of user when the heat exchanger (at this moment, heat exchanger is a condenser) that air-conditioner under the situation of greenhouse running is opened into indoor set rises to set point of temperature, air-supply; Time in the time of till the evaporating temperature that air-conditioner under the situation of cold-room running is opened into the heat exchanger (at this moment, heat exchanger is an evaporimeter) of indoor set reaches dew point.This " certain hour " can come by experiment to determine, also can decide according to outer temperature according to the situation of concrete air-conditioner.Obviously, when outer temperature was low, it is longer that the heat exchanger during the greenhouse running reaches time of set point of temperature; When outer temperature was high, it is longer that being used to of cold-room when running reduced time of evaporating temperature of heat exchanger.By such control, can under different situations, make the best heat exchanger effectiveness of heat exchanger performance, when bringing into play the air-conditioning effect well, also improved user's comfort.
In addition, more than illustrated in the explanation all be for the efficient that improves fan, carry out air quantity and regulate, and in the situation that oral-lateral is installed the wind blade that can swing with left and right directions that blows out of fan housing.
But, for the efficient that reaches raising fan of the present invention, carry out the purpose that air quantity is regulated, also can fan housing blow out that oral-lateral installs can be with upper and lower to the wind blade of swinging, for example, as shown in figure 11.Among Figure 11, the upper and lower sides at fan housing respectively is provided with 1 wind blade respectively, and the turning cylinder of wind blade is connected with drive unit respectively separately, and rotates wind blade by drive unit.Except two blades are arranged on the upper-lower position of fan housing outlet side, other situation with the above-mentioned position, the left and right sides that two blades is arranged on the fan housing outlet side is identical.
When cold-room turned round, when starting, controller wind blade 77 up and down was controlled at it and is in level, perhaps is in along the radial state of air supply direction.
When greenhouse turned round, when starting, in order to reduce air quantity, controller was set in minimum air quantity state with the air quantity of fan.And controller is in the state that has certain angle with respect to air supply direction by making wind blade, makes air-supply receive obstruction, thereby reaches the purpose that reduces air quantity.
And start and through the common operating condition after the certain hour under, controller with upper and lower to swing guide blade.Thus, can improve heat exchanger effectiveness to the air-supply of the bottom of the heat exchanger of the possibility original text that under the immutable state of wind direction, becomes the dead angle.
Pipe type air conditioner of the present invention, by rotating wind blade is set, and the action of wind blade and its locus with respect to the fan housing blow-off outlet, change the air output that blows to heat exchanger, with this efficient that changes heat exchanger, reached the purpose that makes the best heat exchanger effectiveness of heat exchanger performance under the different situations.Not only overcome the problem that exists in the conventional art, also improved user's comfort.
Obviously, from invention described above as can be seen the present invention can change in every way.These changes can not be regarded as a departure from of the present invention will the meaning and scope, and for those of ordinary skills, all such modifications obviously should be contemplated as falling with within the claim scope of the present invention.
