DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to FIG. 1, a supply method without cooling medium for an air conditioner in accordance with the present invention comprises the following steps:
removing moisture: guiding compressed air to a guiding space having at least two sizes of cross sections, with the variation of the cross sections of the guiding space, the compressed air will be collided in the guiding space, such that the flow rate of air is changed, so as to separate the moisture from the compressed air;
separating cold air from hot air: rotating the air produced by the step of removing moisture at a high speed, with the centrifugal force produced by rotation, the cold air and the hot air are separated;
supplying: separating the cold air and the hot air which are produced by the step of separating cold air from hot air, and supplying the cold air and the hot air separately.
The following supply method without cooling medium for an air conditioner comprises an additional water-removing step (as shown in FIG. 2) that makes the following method different from the above-mentioned method, which comprises the steps of:
removing moisture for the first time: guiding compressed air to the guiding space having at least two sizes of cross sections. With the variation of the cross sections of the guiding space, the compressed air will be collided in the guiding space, such that the flow rate of air is changed, so as to separate the moisture from the compressed air;
separating cold air from hot air: rotating the air produced by the step of removing moisture at a high speed, with the centrifugal force produced by rotation, the cold air and the hot air are separated;
removing moisture for the second time: guiding the cold air produced by the step of separating cold air from hot air to the guiding space having at least two sizes of cross sections. With the variation of the cross sections of the guiding space, the compressed air will be collided in the guiding space, such that the flow rate of air is changed, so as to separate the moisture from the compressed air;
supplying: separating the cold air produced by the second water-removing step from the hot air produced by the step of separating cold air from hot air, and supplying the cold air and the hot air separately.
The above-mentioned second moisture-removing step is designed for large flow rate and can be avoided when the flow rate is small.
A system using the above-mentioned supply method without cooling medium for an air conditioner comprises a plurality of air dryers 10, a separator 20 and a cooperating body A.
Referring to FIG. 3, the air dryer 10 comprises a cylinder 11 and a cover 12. One side of the cylinder 11 is provided with an assembling portion 111, and one side of the cover 12 is provided with an assembling portion 121. Each of the assembling portions 111, 121 is formed with a thread section for enabling the cylinder 11 and the cover 12 to be screwed with each other. The cover 12 is defined with an inlet 122 and an outlet 123. The cylinder 11 is combined with the cover 12 to form a receiving space 13. The cylinder 11 can also be integral with the cover 12 to form the receiving space 13 without the assembling portions 111, 121.
In the receiving space 13 is provided an air-moisture separation chamber 14 having at least one laminar separating member 141 which divides the air-moisture separation chamber 14 into at least two guiding spaces 142. The separating member 141 is defined with an air hole 143, such that the guiding spaces 142 are connected with each other. The air holes 143 of the separating members 141 must be arranged in a stagger manner, such that the compressed air moves in a tortuous pattern in the guiding spaces 142 to increase the times of collision, thus further increasing the adhesion amount of moisture and oil gas. The inlet 122 and the outlet 123 of the cover 12 are connected to both ends of the air-moisture separation chamber 14, such that the compressed air flows into the inlet 122 of the cover 12, then passes through the air hole 143 of each separating member 141 of the air-moisture separation chamber 14, and finally is discharged from the outlet 123 of the cover 12.
The separator 20 is provided with a separation chamber 201 and is defined with an inlet 21, a cold outlet 22 and a hot outlet 23. The inlet 21, the cold outlet 22 and the hot outlet 23 are connected to the separation chamber 201. The cold outlet 22 and the hot outlet 23 are located at both ends of the separation chamber 201, and the inlet 21 is provided at one side of the separation chamber 201 and is connected to the outlet 123 of the air dryer 10.
When the air enters the separation chamber 201 from the inlet 21 of the separator 20, it is sprayed out from the inlet 21 into the separation chamber 201 and then rotates in the separation chamber 201 at a high speed, so as to produce a centrifugal force. With the effect of the centrifugal force, the pressure and density of the air close to an inner wall of the separation chamber 201 will be increased, and the pressure and density of the air away from the inner wall of the separation chamber 201 will be decreased, such that the air with high pressure and density will flow to the air with low pressure and density. With the pressure change in the separation chamber 201, the hot air will be discharged from the hot outlet 23, and the cold air will be discharged from the cold outlet 22. The hot outlet 23 provides hot air to the cooperating body A, or the cold outlet 22 provides cold air to the cooperating body A. The cooperating body A can be a chip (as shown in FIG. 3) or a tool machine (as shown in FIGS. 4 and 6). The cold outlet 22 and the hot outlet 23 can be used in the air conditioner as a medium for providing or absorbing heat energy, thus replacing the cooling medium which destroys the earth's environment. Moreover, the cold outlet 22 and the hot outlet 23 can also cooperate with liquid, such as water (industrial water or living water) to provide cold water (as shown in FIG. 5) or hot water (as shown in FIG. 7) via thermal exchange.
Referring to FIG. 3 again, in order to adjust the air flow rate of the hot outlet 23 and the cold outlet 22 of the separator 20, the diameter of the pipelines provided at the hot outlet 23 and the cold outlet 22 can also be designed to be changeable to restrict the flow rate, for example, the diameter of the hot outlet 23 of the separator 20 can be larger than, or smaller than or equal to that of the cold outlet 22. Also, each of the hot outlet 23 and the cold outlet 22 can be assembled with a control valve 30 having a changeable opening to restrict the flow rate.
Referring to FIG. 8, a dust filter 40 and a bacterial filter 50 are assembled between the air dryer 10 and the separator 20, so as to filter the dust and bacteria in the pipelines, providing a healthier and cleaner air.
Referring to FIG. 9, in order to process compressed air of high flow rate, the cold air discharged from the cold outlet 22 often contains moisture, at this moment, an air dryer 10′ must be assembled to the cold outlet 22. The hot air discharged from the hot outlet 23 often contains oil gas, at this moment, an oil-gas separator 80 must be assembled to the hot outlet 23. The above-mentioned air dryer 10′ and the oil-gas separator 80 can be selectively assembled according to the flow rate or oil gas content or moisture content of the compressed air.
Referring to FIG. 10, in order to adjust the temperature of the compressed air, the pipeline connected to the inlet 122 of the air dryer 10 is assembled with an air tank 60 into which the compressed air is guided, that is, the compressed air is guided from a small space to a large space, such that the flow rate of the compressed air is reduced, so as to achieve a cooling effect. The air tank 60 is also used to stabilize pressure of the compressed air. In addition, the pipeline connected between the air tank 60 and the air dryer 10 can be assembled with a fan 70 for dissipating its heat energy. Thereby, the air tank 60 and the fan 70 (as shown in FIG. 11) can be selectively used according to the flow rate and the temperature of the compressed air. Moreover, as to the air compressor A for manufacturing the compressed air which has been designed to have a function of cooling the compressed air, it is unnecessary to assemble the above-mentioned air tank 60 and fan 70.
To summarize, the supply method without cooling medium for an air conditioner comprises the steps of removing moisture, separating cold air from hot air and supplying. Under the condition of no cooling medium, the above-mentioned steps separate the moisture from the compressed air, separate the cold air from the hot air and supply the cold air and the hot air. The system using the supply method without cooling medium for an air conditioner comprises at least one air dryer having an air-water separation chamber for separating air from moisture and at least one separator having a separation chamber for separating cold air from hot air. The separator is connected to a pipeline to supply the cold air and the hot air. The present invention works without cooling medium can prevent the environment from being destroyed, and supplies the cold air and the hot air separately, which allows the user to use the cold air or the hot air according to his/her requirement.
While we have shown and described various embodiments in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
