[0025] The present invention will now be described in further detail with reference to the accompanying drawings.

[0026] Reference Figs. 1-4The evaporative condensing unit includes a body 1, a compressor 2, a refrigeration system 3, an evaporative condensing system 4, a first drip tray 5, and a second drip tray 6. The compressor 2, refrigeration system 3, evaporative condensing system 4, first drip tray 5, and second drip tray 6 are all located inside the body 1. The refrigeration system 3 is connected to the compressor 2. The first drip tray 5 is located below the refrigeration system 3. The evaporative condensing system 4 is correspondingly positioned to the refrigeration system 3. The second drip tray 6 is located below the evaporative condensing system 4. A partition 11 is provided inside the body 1, and the partition 11 is vertically positioned. The compressor 2 is located below the evaporative condensing system 4. The refrigeration system 3 includes a direct-expansion evaporator 32 and an evaporator fan 33. The direct-expansion evaporator 32 is located on one side of the partition 11, and the evaporator fan 33 is located at the direct-expansion evaporator 32. An air outlet 12 is provided on the body 1, and the evaporator fan 33 is correspondingly positioned to the air outlet 12. The evaporative condensing system 4 is located on the other side of the partition 11.

[0027] The cold air generated at the three points of the refrigeration system is transported outward by the evaporator fan 33 and output through the air outlet 12 to achieve a cooling effect. The partition 11 facilitates the partitioning and arrangement of various structures within the unit body 1, improving the compactness of the installation of each structure.

[0028] The refrigeration system 3 includes a condenser 31 and a gas-liquid separator 34. The condenser 31 is connected to the exhaust port of the compressor 2. The direct expansion evaporator 32 is connected to the condenser 31. The evaporator fan 33 is located inside the direct expansion evaporator 32. The first water receiving tray 5 is located below the direct expansion evaporator 32. The condensate collection pipe is located between the water tray 7 described below and the first water receiving tray. The direct expansion evaporator 32 is connected to the suction port of the compressor 2 through the gas-liquid separator 34. The condenser 31 and the evaporator fan 33 are located on opposite sides of the partition 11.

[0029] The refrigeration system 3 also includes a throttling mechanism 35 and a filter 36. The condenser 31 is connected to the direct-expansion evaporator 32 after passing through the filter 36 and the throttling mechanism 35 in sequence. The throttling mechanism 35 is a commonly used throttler in air conditioners, which can play a throttling role.

[0030] In the refrigeration system 3 of this utility model, when the refrigerant is compressed by the compressor 2, it is delivered to the condenser 31. After being condensed into refrigerant liquid by the condenser 31, it is delivered to the throttling mechanism 35 through the filter 36, and then to the direct expansion evaporator 32 to exchange heat with the air. The resulting low-temperature cold air is sent out by the evaporator fan 33 to achieve the cooling of the external environment. The gaseous refrigerant returns to the compressor 2 through the gas-liquid separator 34 to complete the refrigeration process.

[0031] By employing a direct-expansion evaporator 32, heat exchange efficiency is greatly improved, achieving a highly efficient cooling effect. Simultaneously, the first drip tray 5 allows for the collection of condensate from the direct-expansion evaporator 32.

[0032] The evaporative condensation system 4 includes a water distributor 41 and an evaporative condenser fan 42. The water distributor 41 is located above the condenser 31 and is positioned corresponding to the condenser 31. The evaporative condenser fan 42 is located above the water distributor 41, and the second water receiving tray 6 is located below the condenser 31. The evaporative condenser fan 42, the water distributor 41, the condenser 31, and the second water receiving tray 6 are arranged sequentially from top to bottom on the other side of the partition 11. Thus, the reasonable distribution of each corresponding structure on the corresponding side of the partition 11 makes the layout more compact.

[0033] Through the rational arrangement of the various structures within the unit 1, the entire air conditioning structure is made more compact. The entire air conditioning unit has an integrated and compact design, which can be installed indoors and work by connecting to the external air intake and exhaust pipes. It can also be installed near a window or in a recessed installation, directly exchanging heat with the outside through convection. The installation is very simple and can cool the entire interior space.

[0034] By providing a second water receiving tray 6, the water sprayed by the water distributor 41 onto the condenser 31 can be recycled, facilitating water recycling and achieving the effect of saving water resources. The water distributor 41 consists of a water pipe with multiple nozzles, which spray water onto the condenser 31 to cool it down.

[0035] The evaporative condensation system 4 also includes a water collector 43 and packing material 44. The water collector 43 is located between the water distributor 41 and the evaporative condenser fan 42, and the packing material 44 is located above the second water receiving tray 6. The water collector 43 consists of multiple baffles, and the airflow from the evaporative condenser fan 42 passes through the gaps between adjacent baffles before acting on the condenser 31. The water collector 43 serves a waterproof function, preventing water sprayed from the water distributor 41 from acting on the evaporative condenser fan 42. The packing material 44 further cools the sprayed water after heat exchange and prevents splashing.

[0036] The evaporator-condenser integrated unit of this utility model also includes a water pan 7 and a spray water pump 8. The water pan 7 is located inside the body 1. The first water receiving pan 5 and the second water receiving pan 6 are both connected to the water pan 7. The water distributor 41 is connected to the water pan 7 through the spray water pump 8, which is located at the bottom of the body 1.

[0037] In actual use, the water collected in the first water receiving pan 5 and the second water receiving pan 6 flows back to the water pan 7 through the water pipe. The water in the water pan 7 can be pumped to the water distributor 41 by the spray water pump 8, and then acted on the condenser 31 through the water distributor 41. The water flowing down from the condenser 31 flows down to the packing 44, and then flows to the second water receiving pan 6 through the packing 44. The water in the second water receiving pan 6 then flows back to the water pan 7, recovering the condensate generated when the evaporator 32 is working, reducing the water consumption of the entire unit.

[0038] The evaporator-condenser integrated unit of this utility model also includes a drain solenoid valve 9, a cleaning solenoid valve 10 and a nozzle 20. A filter screen 30 is installed in the water pan 7. A water outlet is provided on one side of the water pan 7. The nozzle 20 and the water outlet are located on opposite sides of the filter screen 30. The cleaning solenoid valve 10 is connected to the nozzle 20 and the drain solenoid valve 9 is connected to the water outlet.

[0039] In practical use, a water quality testing device can be installed inside the water pan 7 to monitor the water quality. When poor water quality is detected or after a certain period of air conditioning operation, the drain solenoid valve 9 is opened first, allowing water in the water pan 7 to drain through the outlet and the drain solenoid valve 9. Then, the cleaning solenoid valve 10 is opened, allowing external tap water to be sprayed out through the nozzle 20 at high speed onto the filter screen 30 to clean it. This achieves self-cleaning of the water pan 7, completing the self-cleaning process.

[0040] The evaporator-condenser integrated unit of this utility model also includes a water replenishment electric valve 40, which is located on the outside of the water pan 7, and the outlet of the water replenishment electric valve 40 is connected to the water pan 7. Through the water replenishment electric valve 40, external tap water can be delivered to the water pan 7 to replenish the water in the water pan 7, ensuring that the water distributor can spray water onto the condenser 31.

[0041] The compressor 2, gas-liquid separator 34, and water supply electric valve 40 are all located below the direct expansion evaporator 32. This further improves the compactness of the overall internal structure of the unit 1 and achieves a reasonable arrangement of each structure.

[0042] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present utility model, and these all fall within the protection scope of the present utility model.
