[0022] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0024] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0025] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Furthermore, a first feature being "above," "above," and "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is at a higher level than the second feature. A first feature being "below," "below," and "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0026] refer to Figure 1-4 , shows a constant temperature and humidity fresh air integrated machine, including a body 1, which is divided into a condensation chamber 11 and a fresh air treatment chamber 12 from top to bottom, the condensation chamber 11 is provided with a compressor 2 and a condenser 3, the fresh air treatment chamber 12 is provided with an evaporator 4, the evaporator 4 divides the fresh air treatment chamber 12 into an air inlet section 121 and an air supply section 122, the air inlet section 121 is provided with an air inlet 13, and the air inlet section 121 is provided with a dust filter 133; the air supply section 122 is provided with an air supply fan 5, a heater 6, a humidification tank 7 and a mist outlet pipe 71, the humidification tank 7 is connected to the mist outlet pipe 71 through a pipe, and the air supply section 122 is provided with an air outlet 14.

[0027] Specifically, the constant temperature and humidity fresh air integrated machine can first remove dust from the fresh air, and then remove water vapor in the fresh air and cool the fresh air through the evaporator 4. Thereafter, according to the set temperature and humidity, the heater 6 heats the fresh air to the set temperature, and the humidification tank 7 and the mist outlet pipe 71 humidify the fresh air to the set humidity, so that the temperature and humidity of the fresh air are the same or almost the same as those of the indoor air, avoiding the influence of the fresh air on the indoor temperature and humidity, and achieving the effect of constant temperature and humidity indoors.

[0028] Compressor 2 draws low-temperature, low-pressure refrigerant vapor from evaporator 4. This vapor is adiabatically compressed by compressor 2 to become high-temperature, high-pressure superheated vapor. This vapor is then compressed into condenser 3 for constant-pressure cooling, releasing heat to the cooling medium, and ultimately cooling into a subcooled liquid refrigerant. The liquid refrigerant is adiabatically throttled by an expansion valve (not shown) to become a low-pressure liquid refrigerant. It evaporates in evaporator 4, absorbing heat from the fresh air. The water vapor in the fresh air releases heat and condenses, removing it. The low-pressure refrigerant that flows out is then drawn into compressor 2, and the cycle continues. The operating principles of compressor 2, condenser 3, and evaporator 4 can be referenced in the prior art.

[0029] The humidifier tank 7 converts water into water vapor, which is then transported to the mist outlet pipe 71. The mist outlet pipe 71 is provided with a plurality of mist outlet holes (not shown) through which the water vapor is released. The humidifier tank 7 can be connected to a water storage tank (not shown) via a pipe. The humidifier tank 7 can be ultrasonic humidification, direct evaporation humidification, or electric heating humidification.

[0030] In this embodiment, the body 1 is divided into a condensation chamber 11 and a fresh air treatment chamber 12, which are separated by sheet metal (not marked in the figure). Insulation cotton (not shown) can be attached to the sheet metal to prevent the condenser 3 in the condensation chamber 11 from releasing heat and affecting the temperature in the fresh air treatment chamber 12; the fresh air treatment chamber 12 is divided into an air intake section 121 and an air supply section 122. In this embodiment, the internal space of the body 1 is reasonably divided and the structure is simple, which can avoid the internal modules from affecting each other and facilitate subsequent inspection and maintenance.

[0031] In some embodiments, in order to facilitate the use of the constant temperature and humidity fresh air integrated machine in an outdoor environment, such as a building rooftop, reference Figure 2 and Figure 3 The air inlet 13 is provided with a rain shield 131. The rain shield 131 is in the shape of a pipe. One end of the rain shield 131 is connected to the position of the body 1 corresponding to the air inlet 13, and the other end is tilted downward. In this way, during rainy weather, rainwater cannot enter the fresh air processing chamber 12 through the air inlet 13, thereby avoiding affecting the normal operation of the constant temperature and humidity fresh air all-in-one machine.

[0032] Preferably, reference Figure 3 A safety fire damper 132 is provided in the rain shield 131. The safety fire damper 132 can prevent the fire from spreading through the fresh air system in a fire hazard scenario.

[0033] For details of the above scheme, please refer to Figure 3 An explosion-proof control box 9 is also provided in the condensing chamber 11. The explosion-proof control box 9 can control the parameter settings of each module in the body 1. The explosion-proof control box 9 reaches the IIC level explosion-proof grade to ensure safety.

[0034] In some embodiments, since the condenser 3 releases heat during operation, in order to improve the heat dissipation efficiency of the condenser 3, reference is made to FIG. Figure 2 , a cooling fan 15 is provided on the body 1 at a position on one side of the condensing chamber 11. Further, referring to Figure 1A first access door 16 is provided on the fan, located on the other side of the condensing chamber 11. The first access door 16 is provided with a plurality of hollow holes 161. The provision of the hollow holes 161 facilitates air convection between the condensing chamber 11 and the outside air, thereby improving heat dissipation efficiency. Furthermore, the first access door 16 facilitates access to modules within the condensing chamber 11 (e.g., the condenser 3 and compressor 2).

[0035] For details of the above scheme, please refer to Figure 3 The air supply fan 5 is a volute fan, and the output end of the volute fan is connected to the air outlet 14.

[0036] In some embodiments, to ensure the cooling and dehumidification effect of the fresh air, refer to Figure 3 There are at least two evaporators 4 between the air inlet section 121 and the air supply section 122. In this way, the fresh air passes through multiple evaporators 4 in sequence, ensuring that the fresh air is sufficiently cooled and that the water vapor in the fresh air is completely removed. In addition, refer to Figure 2 and Figure 3 A water receiving pan 8 is provided below the evaporator 4, and the water receiving pan 8 is connected to a drain pipe 81, one end of which is located outside the machine body 1. In this way, the water vapor in the fresh air condenses on the evaporator 4, and the condensed water flows down along the evaporator 4 to the water receiving pan 8, and the drain pipe 81 can drain the water in the water receiving pan 8.

[0037] For details of the above scheme, please refer to Figure 1 A second inspection door 17 is provided on the fan at one side of the fresh air processing chamber 12. The second inspection door 17 facilitates inspection and maintenance of the modules in the fresh air processing chamber 12, such as repairing the air supply fan 5 and replacing the dust filter 133.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
