Description

Technical Field

[0001] The invention relates to the technical field of air conditioning, and in particular to an integrated water-cooled fresh air air conditioner. Background Art

[0002] Water-cooled fresh air air conditioning is a complex and important field. The core is that the water distributor is in a water circulation evaporation and heat dissipation. The fresh air is cooled by the cold air section and then sent into the room. The condensed water enters the water storage basin under the water cooling section through the water receiving pan drain pipe for utilization. The return air section recycles the indoor cold source, and the polluted gas is discharged through the return air exhaust port. However, conventional water-cooled fresh air air conditioning is usually used in large-scale equipment, which requires a lot of funds, complex procedures, large space, and many pipeline gate valves. The present invention overcomes the above problems, and designs an integrated water-cooled fresh air air conditioner by combining the chiller fresh air air conditioning system.

The secondary mixing section is provided with an air duct connected to the air outlet of the exhaust unit. The air duct is a three-way structure. After being discharged from the exhaust unit, one end is connected to the secondary mixing section, and the other end is connected to the outside. The cooling pipeline in the surface cooling section is close to the first inlet end of the evaporator, and the cooling pipeline in the cooling section is close to the first outlet end of the evaporator. Low-grade refrigeration return water is used to first reduce the temperature of the fresh air that has just flowed into the cooling unit, and at the same time, the temperature of the chilled water return water is further increased. The fresh air after preliminary cooling is then mixed with the primary return air, and then the cold water flowing out of the evaporator is used to cool it. This technology relies on chilled water to cool the fresh air, and then the evaporator surface cooler cools it. The structure is complex, and flying dust is also easy to fall on the chilled water to cause pipe blockage. Summary of the invention

[0025] The technical solution of the present invention is further described in detail below through specific embodiments and in combination with the accompanying drawings. The described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] The water-cooled evaporation system of the present invention comprises an evaporator 4, a compressor, a condenser and an expansion valve, a lifter 17, a water distributor 13, a water collection basin 23, a blower, a return blower, and a condensing blower 12. The refrigerant outlet of the compressor is connected to the refrigerant inlet of the condenser through a pipeline, the refrigerant outlet of the condenser is connected to the refrigerant inlet of the expansion valve through a pipeline, the refrigerant outlet of the expansion valve is connected to the refrigerant inlet of the evaporator 4 through a pipeline, the refrigerant outlet of the evaporator 4 is connected to the refrigerant inlet of the compressor, and the heating is reversed through the four-way valve.

[0027] The present invention consists of three main parts, aiming to optimize the use and recycling of water and reduce energy consumption. The first part involves the water replenishment link, which ensures a stable water supply to the system by connecting the indoor water source to the water collection basin 23. In order to effectively manage the water level, the present invention is specially designed with a water level controller, which can monitor the water level in the water collection basin 23 and start the corresponding operation when the water level reaches a predetermined value. When the water level in the water collection basin 23 is too high and close to the full water state, the overflow port equipped with the system will automatically start to guide the excess water to the sewer through the conduit to prevent the water from overflowing and causing waste or damage. This intelligent control mechanism not only ensures the safe operation of the system, but also avoids the unnecessary loss of water resources. The second part is the recycling of condensed water. The condensed water generated during the operation of the air conditioner will be collected in the recycling basin 24. The condensed water is effectively introduced into the water collection basin 23 through the water guide pipe for reuse. This recycling method not only saves water, but also reduces the energy consumed by frequent water replenishment, reflecting the environmental protection and energy-saving characteristics of the system. The third part involves the coordinated work of the supply and return fans, which are responsible for delivering processed hot and cold air into the room and bringing the hot or cold air in the room back to the system for further processing.

The other side of the return air port 9 is connected to a mixing air duct 21, which is responsible for mixing outdoor fresh air and indoor circulating air, and then delivering it to the air inlet box 18 for further cooling or heating treatment.

[0041] The filter 3 is located between the inlet of the air inlet box 18 and the evaporator 4. The filter 3 removes dust, pollen and other particulate matter in the air.

[0046] Example 3: Reference Figures 1 to 7 This embodiment is similar to the main structure of embodiment 1 and embodiment 2.

[0049] In the integrated water-cooled fresh air air conditioner of this embodiment, a condensing fan 12 is installed inside the water distributor 13. In a high temperature environment, this active heat dissipation method is essential for maintaining the stable operation of the air conditioning system. The water distributor 13 is filled with a water absorbent 16, which absorbs and retains water to ensure that water and air can fully contact inside the water distributor, thereby enhancing the heat exchange effect.

[0050] A partition 19 is provided between the air inlet box 18 and the return air box 20, and the partition 19 separates the air inlet box 18 and the return air box 20 to prevent fresh air and indoor air from mixing, thereby ensuring that the air conditioning system can effectively perform air exchange and temperature regulation. In this embodiment, an upper heat dissipation hole 2 is designed above the condensation box 1, and a side heat dissipation hole 11 is designed on the side. The heat dissipation hole 11 quickly dissipates the heat generated inside the condensation box to the external environment through natural convection or forced ventilation.

[0051] The partition plate 19 may be provided with a partition tongue, which allows the air of the return air box 20 to enter the air inlet box 18 for mixing, while the cold air in the air inlet box 18 will not enter the return air box 20, which has higher thermal efficiency and less energy consumption.

[0052] The engine compartment box 7 is specially designed with an engine compartment door 22, which is convenient for maintenance and repair of the internal components of the air conditioning system. The engine compartment door 22 can be easily opened, allowing users or maintenance personnel to quickly access key components such as motors, control systems and compressors. The engine compartment door 22 is equipped with a locking mechanism and a sealing strip to maintain the sealing of the engine compartment box 7 in the closed state, prevent the intrusion of dust and moisture, and ensure the cleanliness and dryness of the interior of the air conditioning system.

[0053] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
