Fresh air integrated machine first cools and dehumidifies the outdoor fresh air, then heats the fresh air, and finally humidifies the fresh air to control the temperature, humidity and oxygen concentration of the fresh air entering the room. When controlling the humidity of the fresh air, it is often done through the humidification component set in the fresh air integrated machine. The humidification component consists of a wet film and a nozzle. The nozzle sprays water on the wet film, and the fresh air blows through the wet film to increase the humidity of the fresh air.

[0003] In the prior art, the electronic components relied on for the automatic control and circuit control of the fresh air integrated machine often cannot be exposed to water, so they are arranged on the side close to the fan cavity. However, when the fresh air enters the fan cavity, the temperature of the fan cavity is often low, which will lower the temperature of the electronic components and cause condensation when the water molecules in the fresh air encounter the electronic components with low temperature. This will affect the service life of the electronic components and there is a risk of short circuit. Therefore, how to solve the condensation phenomenon of electronic components is an urgent problem to be solved. Summary of the invention

[0035] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0036] like Figure 1 and Figure 2 As shown, a compact fresh air integrated machine according to an embodiment of the present application includes a housing 100 and a first storage space formed by the housing 100, wherein an evaporator 200, a reheat coil 300, a humidifying unit 400 and a fan unit 500 are arranged in sequence to form an air passage; a second storage space is also provided in the housing 100, and the second storage space is arranged on one side of the first storage space; an electronic component 600 is provided in the second storage space, and a gap is provided between the electronic component 600 and the first storage space. An air inlet 110 and an air outlet 120 are respectively provided at both ends of the housing 100, and one end of the fan cavity 510 is connected to the air outlet 120. The position of the electronic component 600 in the second storage space is directly opposite to the fan unit 500.

[0037] Specifically, an air inlet 110 is provided at one end of the housing 100, and a filter is provided at the air inlet 110 to filter the fresh air introduced into the room, so as to prevent dust in the air from flowing into the room from the fresh air integrated machine. The filter is modularly arranged, which is convenient for disassembly and installation and saves costs.

[0038] The fresh air integrated machine also includes an evaporator 200 and a reheat coil 300, which are sequentially arranged inside the housing 100, the evaporator 200 is arranged on one side of the air inlet 110, the reheat coil 300 is arranged on the side of the evaporator 200 away from the air inlet 110, and a humidifier 400 is arranged on the other side of the reheat coil 300. Outdoor fresh air is blown into the fresh air integrated machine from the air inlet 110, and then passes through the evaporator 200 to cool and dehumidify the fresh air, and then passes through the reheat coil 300 to heat it to a specified temperature, and then passes through the humidifier 400 to humidify the fresh air to a specified humidity, and then blows into the room through the air outlet 120.

[0039] In a specific embodiment, the fresh air integrated machine further includes a fan unit 500, the fan unit 500 includes a fan chamber 510 and a fan, the fan is arranged in the fan chamber 510, and one end of the fan chamber 510 is connected to the air outlet 120. An electronic component 600 is arranged on one side of the fan chamber 510, and the electronic component 600 is fixedly arranged on a fixed plate 700. The fan chamber 510 includes an isolation plate 520, which is a metal plate perpendicular to the side where the fan is located. There is a gap between the isolation plate 520 and the fixed plate 700, and the fixed plate 700 is arranged parallel to the isolation plate 520. That is, the fixed plate 700 separates the electronic component 600 from the fan chamber 510, and the temperature of the fan chamber 510 cannot affect the temperature of the electronic component 600. Therefore, the temperature of the electronic component 600 is always higher than the dew point temperature, and it is not easy to condense, thereby avoiding the phenomenon of condensation of the electronic component 600, thereby shortening the life or even short circuit.

[0040] In a specific embodiment, the fixing plate 700 includes a back plate 710 and a side plate 720 fixedly connected to the back plate 710, the electronic component 600 is fixedly connected to the back plate 710, and the side plate 720 separates the electronic component 600 in the second accommodation space so that the edge of the electronic component 600 is flush with the edge of the fan unit 500. Providing the side plate 720 on one side of the electronic component 600 can reduce the water vapor of the humidifying unit 400 from entering the area where the electronic component 600 is located from the side of the electronic component 600, thereby preventing the electronic component 600 from short-circuiting.

[0041] Specifically, the electronic component 600 includes a control module such as a PLC and other components, which are fixed on a fixed plate 700. The fixed plate 700 is arranged on one side of the fan cavity 510, and a gap is provided between the fixed plate 700 and the isolation plate 520 of the fan cavity 510. Since the fan cavity 510 has a low temperature and a certain humidity of wind blowing through it, a gap is provided between the fixed plate 700 and the fan cavity 510 to prevent the temperature in the fan cavity 510 from being transferred from the isolation plate 520 on its side to the electronic component 600, thereby causing condensation on the electronic component 600, thereby effectively increasing the service life of the electronic component 600.

[0042] In a specific embodiment, the humidifying section 400 includes a nozzle, a wet film and a water retaining member. One side of the nozzle is connected to an external water source through a water pipe, and water is sprayed out through the nozzle. The spraying direction of the nozzle is directly opposite to the top of the wet film. The water sprayed out of the nozzle can wet the wet film, so the fresh air passing through the wet film increases its humidity. A humidity measuring area 410 is provided between the humidifying section 400 and the fan section 500. The length of the humidity measuring area 410 along the direction of fresh air flow is in the range of 100 mm to 150 mm. The area between the wet film of the humidifying section 400 and the entrance of the fan section 500 is the humidity measuring area 410. A humidity sensor can be provided in the humidity measuring area 410 to detect the humidity of the fresh air flowing therethrough, and then transmit a control signal to a control device such as a PLC. The control device controls the flow rate of the nozzle at the upper end of the wet film to control the water content of the wet film and thus control the humidity of the fresh air. Since a fan is provided at the entrance of the fan unit 500, and the diameter of the fan is smaller than the width of the fan unit 500, the width of the humidity measuring area 410 is set in the range of 100 mm to 150 mm, so that the fresh air humidified by the wet film can all enter the fan cavity 510 after passing through the fan, thereby increasing the utilization rate of the wet film area.

[0043] More specifically, the humidifying unit 400 further includes a water receiving tray, which is arranged below the wet film. The water receiving tray is used to hold water falling from the wet film to prevent the water falling from the wet film from falling into the housing 100 and penetrating to the outside of the fresh air integrated machine.

[0044] Some embodiments of the present application provide a fresh air and temperature adjustment device, including an indoor device and an outdoor device, wherein the indoor device includes the above-mentioned fresh air integrated device, and the outdoor device includes a compressor and an outdoor condenser, wherein the compressor and the outdoor condenser are connected to each other through a pipeline and form a closed pipeline loop with the fresh air integrated device through the pipeline and perform working fluid exchange. At least three working fluid exchange ports 130 are provided on the housing 100, and the evaporator 200 and the reheat coil 300 perform working fluid exchange with the outside world through the three working fluid exchange ports 130.

[0045] The evaporator 200 and the reheat coil 300 are connected to the external device through three working fluid exchange ports 130 so that the working fluid can flow in the closed pipeline loop formed between the internal device and the external device. The three working fluid exchange ports 130 are used to introduce the working fluid in the external device into the internal device. Since the internal device includes the evaporator 200 and the reheat coil 300, at least two working fluid exchange ports 130 are provided on the housing 100 to introduce the first working fluid in the external device into the evaporator 200 and the reheat coil 300 respectively. After the first working fluid undergoes heat exchange in the evaporator 200 and the reheat coil 300, it flows out of the internal device from the remaining working fluid exchange port 130.

[0046] The ratio of the width of the fan chamber 510 to the width of the casing 100 is in the range of 0.1 to 0.4. Specifically, the width of the casing is in the range of 500 mm to 600 mm, and the width of the fan chamber is in the range of 300 mm to 540 mm. It can be seen from the ratio range that the overall width of the fan chamber 510 is slightly different from the width of the casing 100, that is, under the same volume of the fresh air integrated machine, a larger fan chamber 510 can be used, and then a larger fan can be used. Since the fresh air integrated machine exchanges working fluid with the external device through the working fluid exchange port 130 provided on the casing 100, that is, the compressor is placed outside the interior of the fresh air integrated machine, the volume occupied by the compressor and the pipeline provided in the internal machine in the prior art is released, and the noise caused by the frequency conversion and operation of the compressor is also reduced. Therefore, the size of the fan chamber 510 and the fan can be correspondingly increased, so the air intake per unit time is increased, which can meet more user needs.

[0047] The above descriptions are only some preferred embodiments of the present disclosure and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by a specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the above-mentioned inventive concept. For example, the above-mentioned features are replaced with the technical features with similar functions disclosed in the embodiments of the present disclosure (but not limited to) and the technical solutions formed.
