[0033] The names of the messages or information exchanged between multiple devices in the embodiments of the present disclosure are only for illustrative purposes and are not used to limit the scope of these messages or information.

[0034] The present disclosure will be described in detail below with reference to the drawings and in combination with embodiments.

[0035] As Figures 1 to 3 shown, a compact fresh air integrated machine according to an embodiment of the present application includes a housing 100 and a first accommodation space formed by the housing 100. An air inlet 110 and an air outlet 120 are respectively provided at both ends of the housing 100.

[0036] The fresh air integrated machine further includes an evaporator 200 and a reheating coil 300. The evaporator 200 and the reheating coil 300 are arranged in sequence in the first accommodation space to form an air passage. A second accommodation space is provided on one side of the air passage. The evaporator 200 is close to the air inlet 110. A humidifying part 400 is provided on the side of the reheating coil 300 away from the evaporator 200. Among them, the humidifying part 400 includes a nozzle 410, a wet film 420 and a first water baffle 430. The nozzle 410 is arranged at the upper end of the wet film 420. A first water baffle 430 is provided on the side of the nozzle 410 away from the reheating coil 300. The first water baffle 430 is fixedly connected to the housing 100.

[0037] Specifically, an air inlet 110 is provided at one end of the outer shell 100. A filter screen is also provided at the air inlet 110 to filter the fresh air introduced into the room, preventing dust in the air from flowing into the room through the fresh air integrated machine. The filter screen is modularly arranged, facilitating disassembly and installation and saving costs. The fresh air integrated machine further includes an evaporator 200 and a reheating coil 300. The evaporator 200 and the reheating coil 300 are sequentially arranged inside the outer shell 100 to form an air passage. The evaporator 200 is arranged on one side of the air inlet 110, and the reheating coil 300 is arranged on the side of the evaporator 200 away from the air inlet 110. A humidifying part 400 is provided on the other side of the reheating coil 300. Fresh air from outside is blown into the fresh air integrated machine through the air inlet 110, and then the fresh air is cooled and dehumidified by the evaporator 200. The fresh air is then heated to a specified temperature by the reheating coil 300, and then humidified to a specified humidity by the humidifying part 400, and finally blown into the room through the air outlet 120.

[0038] The humidifying part 400 includes a nozzle 410, a wet film 420, and a first water baffle 430. One side of the nozzle 410 is externally connected to an external water source through a water pipe. Water is sprayed out through the nozzle 410. The spraying direction of the nozzle 410 is directly opposite to the top end of the wet film 420. The water sprayed out by the nozzle 410 can wet the wet film 420. Therefore, the fresh air passing through the wet film 420 increases its humidity.

[0039] A humidity sensor is also provided in the humidifying part 400. When the humidity sensor detects that the humidity in the fresh air does not reach the set humidity, it will control the nozzle 410 to increase the spraying amount so that there is more water in the wet film 420. However, when the fresh air blows from one side of the wet film 420 and the nozzle 410 to the other side, the fresh air will blow the water just sprayed out by the nozzle 410 that has not yet entered the wet film 420, and even cause it to float to the fan cavity 510 or even float out from the air outlet 120, resulting in a decrease in the accuracy of the detection result of the humidity sensor and the water floating out from the air outlet 120 affecting the user experience. To avoid the occurrence of this phenomenon, in this embodiment, a first water baffle 430 is provided on the side of the nozzle 410 away from the reheating coil 300, and one side of the first water baffle 430 is fixedly connected to the outer shell 100. The water sprayed out by the nozzle 410 is blocked by the first water baffle 430 and then falls onto the wet film 420, which can prevent the water sprayed out by the nozzle 410 from floating to the fan cavity 510 or floating out from the air outlet 120. Furthermore, it also ensures that all the water sprayed out by the nozzle 410 falls onto the wet film 420, increasing the accuracy of the fresh air humidification by the wet film 420.

[0040] In a specific embodiment, the first water baffle 430 includes a first water baffle plate 431 and a second water baffle plate 432, one end of the first water baffle plate 431 is fixedly connected to the housing 100, the second water baffle plate 432 is fixedly connected to the first water baffle plate 431, and the angle between the plane where the second water baffle plate 432 is located and the plane where the first water baffle plate 431 is located is in a range of 120° to 175°. The first water baffle 430 is a thin plate structure, which is formed by connecting the first water baffle plate 431 and the second water baffle plate 432. The first water baffle plate 431 is roughly parallel to the water spraying direction of the nozzle 410, and when the water in the nozzle 410 is blown away, it is mainly used to block the blown away water. A certain angle is set between the second water baffle 432 and the first water baffle 431. On the one hand, it is to ensure that the first water baffle 431 can block the water sprayed from the nozzle 410, and on the other hand, it can ensure that the area of ​​the wet film 420 is maximized. That is, when the fresh air blows to the second water baffle 432, it can be blown out from the gap between the second water baffle 432 and the wet film 420, avoiding the second water baffle 432 blocking a part of the wet film 420.

[0041] In a specific embodiment, the humidifying unit 400 further includes a water receiving tray 440, which is disposed below the wet film 420. A second water retaining member 450 is provided on one side of the water receiving tray 440 away from the air inlet 110, and the second water retaining member 450 is fixedly connected to the housing 100. The second water retaining member 450 includes a third water retaining plate 451 and a fourth water retaining plate 452, one side of the third water retaining plate 451 is fixedly connected to the housing 100, and the other side of the third water retaining plate 451 is fixedly connected to the fourth water retaining plate 452, and the angle between the third water retaining plate 451 and the horizontal plane ranges from 10° to 60°. The angle between the fourth water retaining plate 452 and the horizontal plane ranges from 65° to 85°.

[0042] The water receiving tray 440 is used to receive the water dripping from the wet film 420. It is arranged below the wet film 420. When fresh air blows through the wet film 420, the water in the water receiving tray 440 is often blown into the fan cavity 510, and finally falls from the air outlet 120 into the room, affecting the user experience. A second water baffle 450 is provided between the water receiving tray 440 and the fan chamber 510. The second water baffle 450 is a thin plate structure, which includes a third water baffle 451 and a fourth water baffle 452. The angle range between the third water baffle 451 and the horizontal plane is 10° to 60°, that is, the third water baffle 451 is inclined relative to the horizontal plane, and the height of the end thereof close to the wet film 420 is lower than the height of the end thereof away from the wet film 420. Therefore, when water is blown onto the surface of the third water baffle 451, it is not easy to be blown into the fan chamber 510, and when the fresh air integrated machine stops working, the water on the third water baffle 451 can flow back to the water receiving tray 440.

[0043] One end of the fourth water baffle 452 is fixedly connected to the third water baffle 451, and the other end is fixedly connected to the water receiving tray 440. The included angle between the fourth water baffle 452 and the horizontal plane ranges from 65° to 85°, and its inclination slope is greater than that of the third baffle 451. Therefore, it can guide the accumulated water on the third water baffle 451 to flow back into the water receiving tray 440 after reaching the fourth water baffle 452, preventing the water on the third water baffle 451 from flowing to the edge of the third water baffle 451 and directly dripping into the water receiving tray 440, thereby avoiding the "tick" water droplet noise and affecting the user experience.

[0044] A humidity measurement area is provided between the humidifying unit 400 and the fan unit 500. The length range of the humidity measurement area along the direction of fresh air flow is from 100 mm to 150 mm. The area between the wet film 420 of the humidifying unit 400 and the inlet of the fan unit 500 is the humidity measurement area. A humidity sensor can be arranged in the humidity measurement area to detect the humidity of the fresh air flowing through here, and then send a control signal to a control device such as a PLC. The control device controls the flow rate of the nozzle 410 at the upper end of the wet film 420 to control the water content of the wet film 420 and further control the humidity of the fresh air. Since a fan 520 is provided at the inlet of the fan unit 500 and the diameter of the fan 520 is smaller than the width of the fan unit 500, the width range of the humidity measurement area is set to be from 100 mm to 150 mm. This can ensure that the fresh air humidified by the wet film 420 can all enter the fan cavity 510 after passing through the fan 520, increasing the utilization rate of the area of the wet film 420.

[0045] As the second aspect of the present application, some embodiments of the present application provide a fresh air and temperature adjustment device, including an indoor unit device and an outdoor unit device. The indoor unit device includes the above-mentioned fresh air integrated machine, and the outdoor unit device includes a compressor and an outdoor condenser. The compressor and the outdoor condenser are connected to each other through a pipeline and are connected to the fresh air integrated machine through a pipeline to form a closed pipeline loop for working medium exchange. At least three working medium exchange ports 130 are provided on the housing 100. The evaporator 200 and the reheating coil 300 perform working medium exchange with the outside through the three working medium exchange ports 130.

[0046] The evaporator 200 and the reheating coil 300 are connected to the outdoor unit device through the three working medium exchange ports 130 so that the working medium can flow in the closed pipeline loop formed between the indoor unit device and the outdoor unit device. The three working medium exchange ports 130 are used to introduce the working medium in the outdoor unit device into the indoor unit device. Since the indoor unit device includes the evaporator 200 and the reheating coil 300, at least two working medium exchange ports 130 on the housing 100 are used to introduce the first working medium in the outdoor unit into the evaporator 200 and the reheating coil 300 respectively. After heat exchange in the evaporator 200 and the reheating coil 300, the first working medium then flows out of the indoor unit device through the remaining one working medium exchange port 130.
