[0021] Furthermore, an air outlet cavity 7 is formed between the left side of the inner wall of the cabinet 2, the top surface of the inner wall of the cabinet 2, the left side of the filter element placement opening 10, and the left side of the hanging basket type oblique frame.

[0022] Furthermore, a temperature and humidity sensor 5 is installed on the left side of the top surface of the air outlet cavity 7 , and a variable frequency EC fan 6 is installed on the right side of the temperature and humidity sensor 5 .

[0023] Furthermore, the hanging basket type oblique frame packaging is installed on a stainless steel partition frame 12 at the bottom of the filter element placement port, and a stainless steel frame 14 is arranged at the bottom of the stainless steel partition frame 12; the stainless steel partition frame 12 and the stainless steel frame 14 are both obliquely designed structures to form a hanging basket type oblique frame; the hanging basket type oblique frame is clamped on the left and right sides of the inner wall of the cabinet 2 through the left bottom end of the stainless steel frame 14 and the right top end of the stainless steel partition frame 12, and a gap is left between the oblique frame and the inner bottom surface of the cabinet 2.

[0024] Furthermore, the stacked oblique air handling mechanism includes an oblique air handling mechanism installed in a stainless steel frame; the oblique air handling mechanism includes a surface cooler 8 and a sensible heat exchange core 13 arranged on the top surface of the surface cooler 8, forming a stacked oblique air handling mechanism.

[0025] Furthermore, if Figure 3 As shown, the sealing strip component includes a first sealing strip 23 and a second sealing strip 24 installed at the bottom and right side of the stainless steel frame 14, a third sealing strip 25 installed between the surface cooler 8 and the sensible heat exchange core 13, and a fourth sealing strip 26 and a fifth sealing strip 27 installed on both sides of the stainless steel partition frame 12, forming a composite sealing strip component.

[0026] Furthermore, a plurality of filter elements 11 are installed in the filter element placement opening 10 .

[0027] Furthermore, a front cover plate 16 is hingedly connected to the cabinet body 2 , and a filter replacement port 21 is provided on the front cover plate 16 at a position relative to the filter element placement port 10 .

[0028] Furthermore, a drain port 18 is provided on the left side of the bottom surface of the cabinet 2; a water inlet pipe 19 and a water outlet pipe 20 are provided on the right side of the bottom surface of the cabinet 2, and the water inlet pipe 19 and the water outlet pipe 20 are respectively connected to the sensible heat exchange core 13 and the surface cooler 8 through threaded hoses.

[0029] Furthermore, the cabinet body 2 is made of polyurethane material to form a polyurethane cabinet body, and the inner wall of the cabinet body 2 is provided with an aluminum skin layer.

[0030] The polyurethane in this design has excellent elasticity, elongation, compression strength and softness, as well as good chemical stability, as well as excellent processability, adhesion, thermal insulation and other properties, and is an excellent buffer material. Since the structure of polyurethane elastomer has two segments, soft and hard, the material can be given high strength, good toughness, wear resistance, oil resistance and other excellent properties through the design of the molecular chain. The polyurethane, known as "wear-resistant rubber", has both the high elasticity of rubber and the rigidity of plastic.

[0031] The working principle of the present invention is as follows: The distinguishing feature of the present design from the conventional fresh air humidity control system is that in the present design, a filter element placement opening 10 is installed on the right side of the top surface of the cabinet 2, a stainless steel partition frame 12 is provided at the bottom of the filter element placement opening 10, and a stainless steel frame 14 is provided at the bottom of the stainless steel partition frame 12; the stainless steel partition frame 12 and the stainless steel frame 14 are both of an oblique design structure, forming a hanging basket-type oblique frame.

[0032] Then, an oblique air handling mechanism is installed in the stainless steel frame 14; the oblique air handling mechanism includes a surface cooler 8 and a sensible heat exchange core 13 arranged on the top surface of the surface cooler 8, forming a stacked oblique air handling mechanism. The oblique structural feature allows the air entering from the air inlet to extend the passage of the incoming air when passing through the obliquely arranged surface cooler 8 and the sensible heat exchange core 13, thereby extending the processing time in the surface cooler 8 and the sensible heat exchange core 13, thereby further extending the time to process the incoming air, and improving the quality and efficiency of air processing.

[0033] In this design, the preferred angle of the dihedral angle ɑ formed between the right side surface of the oblique air handling mechanism and the inner bottom surface of the cabinet 2 is 45°.

[0034] In this design, a plurality of filter elements 11 are installed in the filter element placement port 10. The filter elements 11 use filter elements with different filtering effects. For example, two filter elements 11 are installed in the filter element placement port 10. One filter element 11 is a medium-efficiency filter F7, and the other filter element 11 is a high-efficiency filter H13. Different modes are used for different seasons.

[0035] In this design, in summer mode, the outdoor fresh air (or half of the return air mixed with the fresh air) passes through the medium-efficiency filter F7 and the high-efficiency filter H13, and is pre-cooled by the plate exchanger (sensible heat exchange core 13) and enters the water coil (surface cooler 8) for deep dehumidification (external cold water is required as a prerequisite), and then passes through the plate exchanger to exchange sensible heat with the fresh air to increase the temperature (and cool the fresh air at the same time), and then is sent into the room. The air dew point is controlled by an external proportional water valve (optional). Figure 2 The dotted line shown is the air inlet and return air trajectory line 22 .

[0036] In winter mode, outdoor fresh air (or half of the return air mixed with fresh air) passes through the medium-efficiency filter F7 and the high-efficiency filter H13, is preheated by the plate exchanger and enters the water coil for reheating (external hot water is required as a prerequisite), and then exchanges sensible heat with the fresh air through the plate exchanger (which will cause a temperature drop), and then is sent into the room. The supply air temperature is controlled by an external proportional water valve (optional).

[0037] In this design, the surface cooler is mainly used to cool and dehumidify the air, and the temperature and moisture content of the air change. The principle is to let the heat medium or coolant or refrigerant flow through the inner cavity of the metal pipe, and the air to be treated flows through the outer wall of the metal pipe for heat exchange to achieve the purpose of heating or cooling the air. The heat and moisture exchange of the surface cooler is carried out under the action of the temperature difference and water vapor partial pressure difference between the main air and the boundary layer air close to the outer surface of the heat exchanger. It can realize two air treatment processes: when the boundary layer air temperature is lower than the dew point temperature of the main air, a dehumidification cooling process or a wet cooling process (wet working condition) will occur; when the boundary layer air temperature is lower than the main air temperature but still higher than its dew point temperature, an equal wet cooling process will occur. In the dehumidification cooling process, since there is not only a temperature difference but also a water vapor partial pressure difference between the boundary layer air and the main air, there is not only sensible heat exchange through the heat exchanger surface, but also latent heat exchange accompanied by wet exchange. From this we can see that the surface cooler under wet conditions has a greater heat exchange capacity than under dry conditions, or in other words, for the same surface cooler, when the dry-bulb temperature of the treated air and the water temperature remain unchanged, the higher the wet-bulb temperature of the air, the greater the cooling and dehumidification capacity of the surface cooler.

[0038] In this design, the sensible heat exchange core is a heat exchange device that achieves heat transfer by changing the phase state of a substance. The liquid and gas are heat exchanged by utilizing the characteristic of absorbing heat when the substance changes from liquid to gas. Its working principle is as follows: the liquid enters the sensible heat exchange core and contacts the heat source, and the temperature of the heat source is higher than the boiling point of the liquid. The liquid begins to boil under the heating of the heat source and gradually changes to gas. In this process, the liquid absorbs heat. At the same time, the cooling medium (such as air or water) flows through the sensible heat exchanger from the other side and absorbs the heat released during the transformation of the liquid from gas to liquid. The cooling medium heats up after gaining heat, while the liquid cools down after exchanging heat. The cooling medium continues to flow, and the heat source of the sensible heat exchanger heats the liquid, so that the sensible heat exchange core realizes heat transfer. Its advantages are: heat exchange effect, simple structure, easy use, and it can also make full use of the latent heat in the heat absorption process to improve the heat transfer efficiency. It is widely used in many fields.
