DETAILED DESCRIPTION

(3) In order to make the structure and characteristics as well as the effectiveness of the present invention to be further understood and recognized, the detailed description of the present invention is provided as follows along with embodiments and accompanying figures.

(4) Please refer to FIG. 2. The present invention provides an integrated water-cooled air conditioning device, which is formed by integrating the air conditioning system and the cooling-water circulation system. The water-cooled air conditioning device 1 comprises a compressor 10, a condenser 12, a regulator 14, an evaporator 16 (the above forming air conditioning system), and the cooling water tank device 20 (the cooling-water circulation system). The compressor 10, the condenser 12, the regulator 14, and the evaporator 16 are connected sequentially by a refrigerant piping 101 including refrigerant. The cooling water tank device 20 includes a cooling water tank 21. A water tank region 22 is disposed at the bottom of the cooling water tank 21. The water tank region 22 includes water for performing cooling circulation.

(5) The compressor 10 withdraws the low-temperature low-pressure gas refrigerant from the evaporator 16 via the refrigerant piping 101 and compresses it to high-temperature high-pressure gas refrigerant. The refrigerant piping 101 passing through the compressor 10 enters the water tank region 22 of the cooling water tank 21. The refrigerant piping 101 bends spirally to form a spiral hollo tube and forming the condenser 12. In other words, the condenser 12 is a spiral hollow tube immersed in the water tank region 22 for increasing the area for thermal exchange substantially. At this moment, the condenser 12 is at a high-temperature status and dissipates heat by passing through the water tank region 22. Thereby, the water in the water tank region 22 can be used for dissipation heat. The condenser 12 releases heat in the high-temperature high-pressure gas refrigerant in the refrigerant piping 101 and transforms it to low-temperature high-pressure gas refrigerant. The refrigerant piping 101 passing through the condenser 12 next exits the cooling water tank 21 and is connected to the regulator 14. The regulator 14 (a refrigerant controller) can be an expansion valve or a capillary tube. According to the present embodiment, the regulator 14 is a thermostatic expansion valve used for reducing the pressure of the low-temperature high-pressure gas refrigerant and transforming it to low-temperature low-pressure liquid refrigerant. Next, the refrigerant piping 101 passing through the regulator 14 is connected to the evaporator 16. The evaporator 16 evaporates the low-temperature low-pressure liquid refrigerant, absorbs heat, and transforms it to low-temperature low-pressure gas refrigerant, enabling the surface temperature of the evaporator 16 extremely low. By using the blower 19, the refrigeration capacity (the cooled air) is transported indoors for lowing the room temperature. The blower 19 is disposed on one side of the evaporator 16. Alternatively, the blower 19 is disposed between the evaporator 16 and the cooling water tank 21. Afterwards, the refrigerant piping 101 passing through the evaporator 16 is connected to the compressor 10.

(6) Besides, a water-collecting tank 1 is disposed at the bottom of the evaporator 16. Because the refrigerant absorbs heat in the evaporator 16 and cooling the surface of the evaporator 16, water will be condensed on the surface of the evaporator 16. The condensed water will drop down and be collected in the water-collecting tank 18. The water-collecting tank 18 is connected to a recycle water piping 181, which is connected to the cooling water tank 21. Thereby, the water in the water-collecting tank 18 can flow to the water tank region 22 via the recycle water piping 181 and be used as the water for replenishing the cooling-water circulation system.

(7) Because the compressor 10, the condenser 12, the regulator 14, and the evaporator 16 of the air conditioning system and the cooling water tank device 20 of the cooling-water circulation system are integrated and the condenser 12 is placed in the water tank region 22, the compressor 10, the condenser 12, the regulator 14, the evaporator 16, and the blower 19 can be integrated in a case 11 adjacent to one side of the cooling water tank device 20 (the cooling water tank 21). In other words, the case 11 and the cooling water tank 21 facilitate integration of the air conditioning apparatuses.

(8) As shown in the figure, a circulation fan 29 is disposed at the top of the cooling water tank 21; an air inlet 211 is disposed at the bottom of the cooling water tank 21; an air outlet 291 is disposed above the circulation fan 20 of the cooling water tank 21 for exhausting hot air; and a vent 212 is disposed below the circulation fan 29 of the cooling water tank 21. The air inlet 211 is located slightly above the water tank region 22. The vent 212 and the air inlet 211 can be adjusted according to the operation of the circulation fan 29.

(9) The cooling water tank device 20 further includes a water-drawing device 24 and a spray device 26. The water-drawing device 24 can be an immersion circulation pump placed in the water of the water tank region 22. The water-drawing device 24 is connected to a water-drawing piping 241. According another embodiment, the water-drawing device can be a pumping motor alternatively. The pumping motor is connected to the water tank region 22 via a pumping piping. The spray device 26 is disposed in the cooling water tank 21 and below the circulation fan 29 (the vent 212), and includes a plurality of spray heads 261 connected by piping. The spray device 26 (the spray head 261) is also connected and communicates with the water-drawing piping 241 (or the pumping piping). In addition, a stuffing device 28 (or a stuffing region) is disposed below the spray device 26 in the cooling water tank 21. The stuffing device 28 is used for enabling thermal exchange between water (vapor) and the air. The stuffing device 28 (or the stuffing region) is located above the air inlet 211. Thereby, a spray zone is formed between the plurality of spray heads 261 and the stuffing device 28 (or the stuffing region); a water-dropping region between the stuffing device 28 (or the stuffing region) and the water tank region 22.

(10) When the integrated water-cooled air conditioning device 1 according to the present invention operates, because the refrigerant piping 101 enters the water tank region 22 and the refrigerant piping 10 is spirally bent to a spiral hollow tube for forming the condenser 12 and immersed in the water tank region 22 for performing thermal exchange, the temperature of the cooling water in the water tanks region 22 is increased. The water-drawing device 24 (the immersion circulation pump) draws the cooling water in the water tank region 22 to the spray device 26 for spraying through the plurality of spray heads 261. The sprayed hotter cooling water is cooled by the spray zone, the stuffing region, and the water-dropping region and then falls to the water tank region 22 for the usage of the cooling-water circulation system. Meanwhile, due to the operation of the circulation fan 29, the external cold air can enter the cooling water tank 21 via the air inlet 211. The cold air passes through the water-dropping region, the stuffing device 28 (or the stuffing region), and the spray zone for cooling the water and is exhausted from the cooling water tank 21 via the air outlet 291. Then the operation of the cooling-water circulation system is completed.

(11) According to an appropriate embodiment, a vent 213 can be disposed at the cooling water tank 21 opposing to the stuffing device 28 (or the stuffing region). The vent 213 is also approximately opposing to the blower 19 of the cooling water tank 21. Thereby, a portion of the external cold air entering the cooling water tank 21 via the air inlet 211 can be vented by the blower 19 via the vent 213 after entering the stuffing device 28 (or the stuffing region) for cooling the evaporator 16. Because the water-collecting tank 18 and the recycle water piping 181 connected to the cooling water tank 21 are disposed below the evaporator 16, the vapor exhausted via the vent 213 can be condensed by the evaporator 16 and recycled.

(12) By using the above disposal according to the present invention, the air conditioning system and the cooling-water circulation system can be connected integrally, making the overall size miniaturized and solving the drawbacks of long heat-dissipating circuit, high pressure loss, and large size. Thereby, the assembling costs will be reduced, the future maintenance will be convenient, and the economic benefit will be enhanced. In addition, the present invention can further integrate the thermal exchange of the cooling water tank and the condenser and hence improving the thermal exchange efficiency significantly. Moreover, the present invention can recycle the condensed water formed by the evaporator and the vapor carried by the heat-dissipating airflow effectively and replenish the cooling-water circulation system effectively, enabling superior water saving.

(13) Accordingly, the present invention conforms to the legal requirements owing to its novelty, nonobviousness, and utility. However, the foregoing description is only embodiments of the present invention, not used to limit the scope and range of the present invention. Those equivalent changes or modifications made according to the shape, structure, feature, or spirit described in the claims of the present invention are included in the appended claims of the present invention.
