Description

Technical Field

[0001] The utility model belongs to the technical field of air conditioners, and particularly relates to a mobile air conditioner with a double-group cooling structure. Background Art

[0002] At present, most household and commercial air conditioners adopt the method of spraying water onto the condenser through a water wheel to atomize or spray, increasing the contact area and taking away the heat on the condenser to achieve the purpose of cooling. However, it has the disadvantages of loud water spraying and mechanical noise.

[0003] For example, patent CN200943914Y adopts the method of spraying, pumping water to the condenser for cooling through spraying. This solution also has the disadvantage of loud mechanical noise. Summary of the Utility Model

[0004] In view of the above problems existing in the prior art, the purpose of the embodiment of the utility model is to provide a mobile air conditioner with a double-group cooling structure.

[0005] The technical solution adopted in the embodiment of the utility model is a mobile air conditioner with a double-group cooling structure, including a refrigeration system. A condenser and an evaporator are arranged in the refrigeration system. An auxiliary cooling system is connected to the condenser, and the auxiliary cooling system assists the condenser in cooling. Directly cooling the condenser by using the auxiliary cooling system can improve the cooling efficiency.

[0006] Further, the auxiliary cooling system includes a water curtain. The water curtain and the condenser form a cooling module. A water tank for spraying water onto the water curtain and the condenser is arranged above the cooling module. A water receiving tray is arranged below the cooling module. The water tank is connected with a water supply pipeline, and the water receiving tray is connected with a drainage pipeline. The water tank sprays water onto the condenser to directly cool the condenser. The water flows through the surface of the condenser without generating noise. The water tank sprays water onto the water curtain. When air passes through the wet water curtain, the water in the water film will absorb the heat in the air and evaporate to take away a large amount of heat, reducing the temperature of the air passing through the wet water curtain to achieve the purpose of cooling.

[0007] Further, the auxiliary cooling system further includes a water pump and a water tank. One end of the water supply pipeline far away from the water tank communicates with the bottom cavity of the water tank. The water pump is installed on the water supply pipeline. The water supply pipeline supplies water to the water tank. One end of the drainage pipeline far away from the water receiving tray communicates with the water tank, so that the water in the water receiving tray can flow back to the water tank. A self-supplying water solution is provided to enable operation without a water source.

[0008] Further, the water curtain and the condenser in the cooling module are arranged side by side. The condenser can transfer heat to the water curtain through heat conduction or radiation. Then, when air passes through the wet water curtain, the water in the water film will absorb the heat in the air and evaporate to take away a large amount of heat to achieve cooling.

[0009] Further, a plurality of diversion holes are formed on both sides of the water tank. The diversion holes divert water to the water curtain and the condenser, which can reduce the water flow and indirectly reduce the noise generated by the water flow.

[0010] Further, the diversion holes are inclined, and the included angle between the diversion holes and the water flow path in the water tank is not greater than 90°. The inclined arrangement of the diversion holes can make the water flow smooth.

[0011] Further, a hot section and a cold section are constructed. Air inlets and air outlets are provided on both the hot section and the cold section, and fans are installed in both the hot section and the cold section to enable air to enter from the air inlet and exit from the air outlet. The evaporator is installed at the air inlet or the air outlet of the cold section, and the cooling module is installed at the air inlet or the air outlet of the hot section. The hot section and the cold section achieve separation of heat and cold, avoiding mutual influence between the evaporator and the cooling module.

[0012] Further, the cold section is arranged above the hot section. This conforms to the practical scenario. In the actual practical scenario, hot air floats upward and is often located at a high position. The cold section above can cool the hot air at a high position.

[0013] Further, the inner cavities between the hot section and the cold section are not connected. This avoids the mixing of air in the inner cavities of the hot section and the cold section and affects the use effect.

[0014] Further, the refrigeration system further includes a compressor and a capillary tube. A refrigerant cycle is constructed among the compressor, the capillary tube, the condenser and the evaporator, so that the refrigerant flows through the condenser, the capillary tube and the evaporator in sequence starting from the compressor and then returns to the compressor.

[0015] Compared with the prior art, for the mobile air conditioner with a double-group cooling structure proposed by the present utility model, the water curtain and the condenser are arranged side by side, and the water flow directly sprays onto the water curtain and the condenser, realizing the cooling of the condenser by wetting the water curtain and the cooling of the condenser by the water flow directly flowing onto the radiator fins of the condenser. The two groups of cooling are carried out simultaneously, greatly improving the cooling efficiency. In addition, the water flow directly sprays onto the water curtain and the condenser, having the advantage of low noise.

[0016] It should be understood that the foregoing general description and the following detailed description are only exemplary and explanatory and are not used to limit the present utility model.

[0024] In order to keep the following description of the embodiments of the utility model clear and concise, the detailed descriptions of known functions and known components are omitted in the utility model.

[0025] Refer to Figures 1 to 3 , an embodiment of the present utility model provides a mobile air conditioner with a double-group cooling structure, including a refrigeration system. A condenser 1 and an evaporator 2 are arranged in the refrigeration system. An auxiliary cooling system is connected to the condenser 1, and the auxiliary cooling system assists in cooling the condenser 1. Directly cooling the condenser by using the auxiliary cooling system can improve the cooling efficiency.

[0026] The auxiliary cooling system includes a water curtain 3. The water curtain 3 and the condenser 1 form a cooling module. A water tank 4 for spraying water onto the water curtain 3 and the condenser 1 is arranged above the cooling module. A water receiving tray 5 is arranged below the cooling module. The water tank 4 is connected with a water supply pipe, and the water receiving tray 5 has a drainage pipe. The water tank 4 sprays water onto the condenser 1 to directly cool the condenser 1. The water flows through the surface of the condenser 1 without generating noise. The water tank 4 sprays water onto the water curtain 3. When air passes through the wet water curtain 3, the water in the water film will absorb the heat in the air and then evaporate to take away a large amount of heat, so that the temperature of the air passing through the wet water curtain 3 is reduced, thus achieving the purpose of cooling. When in use, a water source can be connected by using the water supply pipe.

[0027] Another self-supplying water solution is provided to enable operation without a water source. The auxiliary cooling system further includes a water pump 6 and a water tank 7. One end of the water supply pipe far away from the water tank 4 communicates with the bottom cavity of the water tank 7. The water pump 6 is installed on the water supply pipe, and the water supply pipe supplies water to the water tank 4. One end of the drainage pipe far away from the water receiving tray 5 communicates with the water tank 7, so that the water in the water receiving tray 5 flows back to the water tank 7.

[0028] In the cooling module, the water curtain 3 and the condenser 1 are arranged side by side. The condenser 1 can transfer heat to the water curtain 3 through heat conduction or radiation. Then, when air passes through the wet water curtain 3, the water in the water film will absorb the heat in the air and then evaporate to take away a large amount of heat, realizing cooling.

[0029] A plurality of diversion holes 8 are opened on both sides of the water tank 4. The diversion holes 8 divert the water to spray onto the water curtain 3 and the condenser 1, which can reduce the water flow and indirectly reduce the noise generated by the water flow.

[0030] To ensure the smooth flow of water, the diversion holes 8 are arranged obliquely. Specifically, the included angle between the diversion holes 8 and the water flow path in the water tank 4 is not greater than 90°.

[0031] It is constructed with a hot section and a cold section. Air inlets and air outlets are arranged on both the hot section and the cold section. Fans 9 are installed in both the hot section and the cold section, so that air enters from the air inlet and exits from the air outlet. The evaporator 2 is installed at the air inlet or air outlet of the cold section, and the cooling module is installed at the air inlet or air outlet of the hot section. The hot section and the cold section achieve separation of heat and cold, avoiding mutual influence between the evaporator and the cooling module.

[0032] To fit the practical scenario, the cold section is arranged above the hot section. In the actual practical scenario, hot air rises and is usually located at a high place. Having the cold section above can cool the hot air at a high place.

[0033] The inner cavities between the hot section and the cold section are not connected. This avoids the mixing of air in the inner cavities of the hot section and the cold section, which may affect the use effect.

[0034] The refrigeration system further includes a compressor 10 and a capillary tube 11. A refrigerant cycle is constructed among the compressor 10, the capillary tube 11, the condenser 1 and the evaporator 2, so that the refrigerant starts from the compressor 10 and flows through the condenser 1, the capillary tube 11 and the evaporator 2 in sequence, and then returns to the compressor 10.

[0035] This technical solution adopts a dual-group cooling mode. One group is the water curtain 3 for cooling, and the other group is the condenser 1 for cooling. The water curtain 3 and the condenser 4 are arranged side by side, and the water circulation of the water tank 7 can enter the water trough 4. A plurality of shunt holes 8 are opened on both sides of the water trough 4 to evenly flow the water into the water curtain 3 and the condenser 1. The two groups of cooling are carried out simultaneously, and the cooling efficiency is high. In addition, a water pump 6 is used to pump water, which has lower noise compared with spraying and other methods.

[0036] When starting refrigeration, the compressor 10 compresses the refrigerant into a high-temperature and high-pressure gas and passes it through the condenser 1. The surface temperature of the condenser 1 is very high and needs to be cooled quickly. The water pump 6 is started to pump water from the water tank 7 into the water trough 4. The water flows into the water curtain 3 and the condenser 1 respectively along the shunt holes 8 on both sides of the water trough 4. The fan 9 in the hot section is started, and the external air enters the water curtain 3. The external air is cooled by passing through the water curtain 3 and then blows onto the radiator fins of the condenser 1. On the other side, the water directly flows from the water trough 4 to the radiator fins of the condenser 1, enabling the condenser 1 to be cooled quickly. The two are cooled simultaneously, and the high-temperature and high-pressure refrigerant in the condenser 1 is cooled faster and more efficiently. After cooling, the refrigerant passes through the capillary tube 11 and reaches the evaporator 2. At this time, the evaporator 2 absorbs a large amount of heat and quickly becomes cold. The fan 9 in the cold section blows over the cold evaporator and blows out the cold air.

[0037] The above description is intended to be illustrative rather than restrictive. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present disclosure. Moreover, the above examples (or one or more of their solutions) can be combined with each other, and considering these embodiments, they can be combined with each other in various combinations or arrangements.
