[0018] Figure 1 It is a schematic diagram of the overall structure provided by the utility model. DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1As shown, this embodiment provides: a dual-cooling split air conditioner, including an outdoor unit and an indoor unit, the outdoor unit 1 includes an outdoor unit housing 1, an evaporative filter 13, a cooling pump 12 and an axial flow fan 11 are installed in the outdoor unit housing 1, air inlet channels are arranged on both sides of the outdoor unit housing 1, the axial flow fan 11 is installed on the top of the outdoor unit housing 1, a cooling pump 12 is installed under the axial flow fan 11, and evaporative filters 13 are connected to both sides of the cooling pump 12. The evaporative filter 13 is located at the air inlet end of the air inlet channel, and the axial flow fan 11 drives the outside air to reduce the high-temperature water in the work to normal temperature water through the evaporative filter 13, and the normal temperature water passes through the cooling pump 12 to form a gaseous refrigerant;

[0021] The indoor unit includes an indoor unit shell 2, in which an evaporator 23, an expansion valve 24, a condenser 22 and a compressor 21 are installed. The evaporator 23 is installed on the top of the indoor unit shell 1, and the evaporator 23 is connected to the expansion valve 24. A compressor 21 is installed at the bottom of the indoor unit shell 1, and the compressor 21 is connected to the condenser 22. The gaseous refrigerant formed by the outdoor unit enters the indoor unit and undergoes compression process, condensation process, throttling process and compression process to cool the air. The gaseous refrigerant formed in the outdoor unit enters the compressor 21 in the indoor unit for a compression process. The compressor 21 compresses the gaseous refrigerant into a high-temperature and high-pressure state, causing a pressure difference in the refrigerant in the pipeline to facilitate flow. The high-temperature and high-pressure gaseous refrigerant is then sent to the condenser 22 through a pipeline for a condensation process. The condenser 22 dissipates heat through the engine fan to reduce the temperature of the gaseous refrigerant. The cooled gaseous refrigerant becomes a normal-temperature and high-pressure liquid under the action of high pressure to facilitate heat absorption and cooling during the evaporation process. The normal-temperature and high-pressure liquid refrigerant after passing through the condenser 22 is transported to the expansion valve 24 for a throttling process. This process again cools and depressurizes the liquid refrigerant, thereby forming a low-temperature and low-pressure liquid refrigerant, and the refrigeration effect is controlled by adjusting the refrigerant flow rate. The low-temperature and low-pressure refrigerant flows into the evaporator 23, fully absorbs heat and vaporizes in the evaporator 23, cools the air around the evaporator, and becomes a low-temperature and low-pressure gaseous refrigerant again.

[0022] Furthermore, a water separator 14 is further provided in the outdoor unit housing 1 . The water separator 14 is located at the bottom of the outdoor unit housing 1 . The water separator 14 is connected to the evaporation filters 13 on both sides respectively.

[0023] Furthermore, the water separator 14 is also connected to the cooling pump 12 .

[0024] Furthermore, a centrifugal fan 26 and a four-way valve 25 are also provided in the indoor unit housing 2. The centrifugal fan 26 is installed at the lower end of the expansion valve 24, and the four-way valve 25 is located on the condenser 22. One end of the centrifugal fan is connected to the expansion valve 24, and the other end is connected to the condenser 22 with a group of channels in the four-way valve 25.

[0025] Furthermore, one end of another group of channels in the four-way valve 25 is connected to the evaporator 23 , and the other end is connected to the condenser 22 .

[0026] Furthermore, an air outlet 28 is provided on the outside of the indoor unit casing 2 , and the air outlet 28 is communicated with the evaporator 23 in the indoor unit casing 2 .

[0027] Furthermore, a filter 27 is provided between the air outlet 28 and the evaporator 23 . The filter 27 is installed in the indoor unit housing 2 and is located at the air outlet 28 . The filter 27 is connected to the upper end of the evaporator 23 .

[0028] Furthermore, a connecting pipe 3 is provided between the outdoor unit housing 1 and the indoor unit housing 2, and the refrigerant enters the compressor 21 through the connecting pipe 3. The connecting pipe 3 is made of PVC material, eliminating the problems of copper pipe welding and copper pipe length limitation.

[0029] The utility model adopts a working mode combining main water cooling and auxiliary air cooling as a whole. The outdoor unit adopts a circulating condensation technology. The axial flow fan 11 drives the outside air to reduce the high-temperature water in the work to normal temperature water through the evaporative filter 13. The normal temperature water then passes through the cooling pump 12 to form a refrigerant. The refrigerant enters the compressor 21 in the indoor unit through the connecting pipe 3. After the compressor 21 compresses the refrigerant into a high-temperature and high-pressure gas, it is sent to the condenser 22 to take away the heat to form a normal temperature liquid refrigerant. After the normal temperature liquid refrigerant enters the four-way valve 25, it is throttled by the expansion valve 24 to form a low-temperature and low-pressure liquid refrigerant, which flows into the evaporator 23 for sufficient heat exchange. After being driven by the centrifugal fan 26 to form cold wind, it passes through the filter 27 and is blown out from the air outlet 28. The low-temperature liquid refrigerant exchanges heat with the indoor air in the evaporator 23 and the temperature rises. Under the pressure of the outdoor unit cooling pump 12, it enters the water distributor 14 and flows through the evaporative filter 13 for reciprocating circulation, maximizing the energy efficiency ratio, reducing emissions and saving energy. The four-way valve 25 switches the heating effect in the same way, with reverse circulation.
