The refrigerant circulation system includes a compressor 310, a condenser 320, a throttling device 330 and an evaporator connected in sequence through refrigerant pipes. The air circulation system includes an air outlet system and a return air system.

The air outlet system includes an air outlet box 100, an air outlet fan 140 and an evaporator. The air outlet box 100 is constructed with an air outlet air duct 110 , the air inlet 120 and the air outlet 130 are arranged opposite to each other, and the air outlet air duct 110 is a straight air duct. In this way, the output air volume of the air outlet system of the mobile air conditioner can be increased under the condition that the fan power is constant.

The air outlet fan 140 is an axial flow fan, and the moving direction of the air in the air outlet air duct 110 is consistent with the direction of the motor shaft of the air outlet fan 140 . The direction of the air does not change when entering the air outlet duct 110 and when it leaves the air outlet air duct 110 , so the air volume of the air outlet fan 140 is large and the air supply distance is long. In a larger space or open space, the mobile setting position is far away from the user, which can not only reduce the impact of fan noise on the user, but also make the wind blown by the mobile air conditioner dispersed by using the characteristics of long air outlet distance. This results in a more uniform cooling effect.

The air outlet fan 140 is in the form of an axial flow fan, which is simple to install and has a low cost.

The return air system includes a return air box 200 , a condenser 320 and a return air fan 240 . The air return box 200 is constructed with a return air port 220 and an air outlet 230. The air enters the air return box 200 from the air return port 220, passes through the condenser 320 to dissipate heat to the condenser 320 and the temperature rises, and then is discharged from the air outlet 230 back to the air return box 200.

A return air system is provided, on the one hand, to dissipate heat from the condenser 320, so that the cooling of the air conditioner can be carried out continuously; The air duct is exhausted through the air outlet 230, which can promote the air flow in the space where the air conditioner is located. The hot air discharged from the air outlet 230 may be discharged in a form according to the usage scenario. For example, when cooling a high-temperature outdoor worker, the air supply port is directed toward the outdoor worker or the location of the outdoor worker, and the hot air discharged from the air outlet 230 may not be directed toward the outdoor worker. When the overall temperature of the environment where the mobile air conditioner is located is not likely to decrease, for example, when cooling down in front of the furnace in an ironworks, the air supply port is directed to the work position in front of the furnace, and the hot air blown by the exhaust port 230 is not directed toward the front of the furnace. location. When the temperature of the environment where the mobile air conditioner is located is likely to be lowered, for example, in a closed or semi-closed workshop that does not operate at a high temperature, the hot air discharged from the air outlet 130 can be discharged outside to reduce the overall temperature of the environment.

Optionally, the plate heat exchanger 340 is located in the return air box 200 . In this way, the refrigerant circulation system can be completely arranged in the air return box 200, and the structure is relatively compact. The refrigerant pipes have high pressure pipes and low pressure pipes, and the refrigerants are also corrosive to a certain extent. Therefore, the refrigerant pipes are mostly hard copper pipes. The water pipe connected between the surface cooler 350 and the plate heat exchanger 340 may be a hose. The plate heat exchanger 340 is disposed in the return air box 200, and the space between the return air box 200 and the air outlet box 100 may be separated. In some scenarios, the air outlet box 100 is located close to the preset cooling area, and the return air box 200 is located away from the preset cooling area, so that the hot air discharged from the return air box 200 is far away from the target The cooling area can also reduce the impact of the noise generated by the refrigerant circulation system on the preset cooling area. The plate heat exchanger 340 is arranged in the air return box 200, which shortens the length of the refrigerant connection pipe and reduces the charging amount of the refrigerant. Such a setting form not only saves the cost, but also facilitates the use of the user.

Optionally, the water pump 360 is located in the return air box 200 . The water pump 360 is arranged in the return air box 200, and the air outlet box 100 will not transmit the noise of the water pump 360 to the target cooling area when the air is discharged. Meanwhile, components such as the water pump 360 and the compressor 310 are located in the air return box 200 , which not only facilitates the heat dissipation of the water pump 360 and the compressor 310 , but also makes the internal structure of the air return box 200 more compact.

Optionally, the connecting water pipe is also provided with a water injection port, and the water circulation system is supplemented with water through the water injection port. A water injection port is provided to facilitate the water filling and drainage of the water circulation system.

Optionally, the mobile air conditioner further includes an exhaust valve, which is arranged on the water circulation pipeline and is located at the highest position of the water circulation pipeline.

Optionally, the mobile air conditioner further includes an exhaust duct connected to the exhaust port 230 . The air outlet 130 of the mobile air conditioner blows out cold air, and the position facing the air outlet 130 is a preset cooling position. The air outlet 230 discharges hot air, and the air outlet 230 is connected to the air exhaust duct, and the hot air discharged from the air outlet box 100 can be discharged to a preset position as required. For example, the hot air is exhausted to the other side of the preset cooling position or the hot air is exhausted to the outside of the environment where the air conditioner is located. An exhaust duct is provided, which can make the exhaust mode of the mobile air conditioner more flexible.

Optionally, the exhaust duct is a flexible hose. The exhaust method can be determined by setting the direction of the flexible hose, and the use of the mobile air conditioner is more flexible.

Optionally, the mobile air conditioner further includes a fixing bracket 400 , one end of the fixing bracket 400 is connected to the air return box 200 , and the other end is connected to the air outlet box 100 ; The air outlet box 100 has a certain distance between the return air box 200 and the air outlet box 100 .

Although the air outlet box 100 and the return air box 200 are independent of each other in the air circulation system, the air outlet box 100 and the return air box 200 are located at the same time in the refrigerant circulation system. Moreover, the refrigerant pipes used for the connection of the refrigerant circulation system are copper pipes, therefore, the relative position between the air outlet box 100 and the return air box 200 needs to be kept fixed. However, the temperatures in the air outlet box 100 and the air return box 200 are not the same. The close arrangement of the air outlet box 100 and the return air box 200 will cause the heat in the return air box 200 to be transferred to the air outlet box 100 . affect the cooling efficiency of the air conditioner. A fixing bracket 400 is provided, which can separate the air outlet box 100 and the air return box 200, thereby improving the cooling effect of the mobile air conditioner.

Optionally, the fixing bracket 400 is arranged vertically, and the air outlet box 100 is located above the air return box 200 .

The air outlet box 100 is located above the return air box 200, and the air outlet box 100 blows cold air from above. The cold air blows to the preset cooling position, the density of the cold air is less than the density of the hot air, and the cold air falls, so that the preset cooling position can be covered by the cold air, so as to obtain a better cooling effect. In this case, the fixing bracket 400 serves to structurally connect the air outlet box 100 and the air return box 200 on the one hand, and to increase the height of the air outlet box 100 on the other hand. The position of the air outlet box 100 is relatively high, which is conducive to better cooling of the mobile air conditioner. Moreover, the compressor 310 is arranged in the return air box 200, the overall weight of the return air box 200 is relatively large, and the air outlet box 100 is arranged above the return air box 200, so that the mobile air conditioner can be more stable when standing on the ground.

The return air fan 240 is an axial flow fan, and the moving direction of the air in the return air duct 210 is consistent with the direction of the motor shaft of the return air fan 240 . The direction of the air does not change when it enters the return air duct 210 and when it leaves the return air duct 210 , so the air volume of the return air fan 240 is large and the air supply distance is long. A large air volume is conducive to cooling the refrigerant in the condenser 320, and a long air supply distance can send hot air to an area far from the preset cooling position, which can improve the cooling effect of the mobile air conditioner. In addition, the air outlet fan 140 is in the form of an axial flow fan, which is easy to install and has a low cost.

Optionally, the air return opening 220 of the return air box 200 of the mobile air conditioner is larger than the air exhaust opening 230 of the return air box 200 .

If the negative pressure is large, the dust or debris near the air return port 220 is likely to be sucked into the air return air duct 210, and the high wind speed will lead to louder noise. Therefore, on the one hand, the larger return air port 220 can prevent foreign objects from being sucked into the return air duct 210, and on the other hand, it can also reduce the noise when the portable air conditioner is running. In addition, the larger air inlet 120 can also increase the air volume during the return air, and further improve the heat dissipation effect of the condenser 320 . The exhaust port 230 is used to discharge the hot air passing through the condenser 320 . When an exhaust duct is connected to the exhaust port 230 , the diameter of the exhaust duct is greater than or equal to the diameter of the exhaust port 230 . Therefore, the exhaust air should not be too large. The air return port 220 of the mobile air conditioner is larger than the air outlet port 230, which can improve the air circulation capability of the mobile air conditioner and reduce the operating noise of the mobile air conditioner.

Optionally, when moving the air conditioner, the air outlet direction of the air outlet 130 of the air outlet box 100 is different from the air outlet direction of the air outlet 230 of the return air box 200 .

The direction of the air outlet 130 is different from the direction of the air outlet 230 , the air outlet 130 blows cold air to a preset cooling position, and the hot air of the air outlet 230 is discharged to other positions. The air outlet 130 and the air outlet 230 discharge air in different directions. In some scenarios, the air outlet 230 can directly discharge air without an air exhaust duct. Such an arrangement form facilitates the use of the mobile air conditioner.
