Description

Technical Field

[0001] This utility model belongs to the field of fresh air, specifically relating to a fresh air treatment device for a five-constant system. Background Technology

[0002] The Five Constant System, namely constant temperature, constant humidity, constant oxygen, constant cleanliness, and constant air quality, is a truly intelligent independent temperature and humidity control system designed for human comfort and health. It combines temperature control via thermal radiation, an independent fresh air system, and displacement ventilation, and is based on artificial intelligence, the Internet of Things, and big data. By sensing indoor and outdoor air environments and learning user needs, it provides users with a "healthy, comfortable, green, and convenient" living environment that can be controlled by zones.

[0003] Currently, the core equipment of the existing five-constant system consists of an air source heat pump and a fresh air system. The air source heat pump has an internal condenser tube and can exchange heat with the outdoor air entering the room. Specifically, it has a cooling mode and a heating mode. When the outdoor temperature is higher than the indoor temperature, the air source heat pump operates in cooling mode, with low-temperature cold water flowing through the internal condenser tube as the refrigerant, continuously outputting and returning to the room through the pipes. When the outdoor temperature is lower than the indoor temperature, the air source heat pump operates in heating mode, with high-temperature hot water flowing through the internal condenser tube as the heat medium, continuously outputting and returning to the room through the pipes. The fresh air system includes a dehumidifier and a humidifier, used to humidify or dehumidify the air entering the room. Utility Model Content

[0007] Preferably, both ends of the condenser coil are connected to an external air source heat pump. Fluid is introduced into the condenser coil from the air source heat pump. The condenser coil exchanges heat with the flowing gas through the internal fluid, and the fluid inside the condenser coil eventually flows back to the air source heat pump.

[0008] Preferably, the present invention further includes a communication module, a control module, and a user terminal. The control module is signal-connected to the two-position three-way valve, the communication module is signal-connected to the control module, the user terminal is used to send a switching signal, the communication module is used to receive the switching signal and transmit it to the control module, and the control module is used to control the two-position three-way valve to connect the condenser housing to either the humidifier housing or the dehumidifier housing.

[0009] Preferably, the humidification unit also includes a water inlet pipe and a water collection tray, both located inside the humidification shell. The water inlet pipe, the water-hanging wet membrane, and the water collection tray are arranged vertically from top to bottom. The water inlet pipe is connected to an external water supply device. The circumference of the water inlet pipe has multiple downward-facing spray holes, and the lower part of the water collection tray has an open drainage pipe.

[0010] Furthermore, the drainage pipe is connected to the air source heat pump.

[0011] Preferably, the dehumidification unit further includes an internal support and a drive motor. The internal support is fixed inside the dehumidification housing. The axes of the drive motor and the molecular sieve rotor are parallel and rotatably mounted on the internal support. A tension wheel is fixed on the output shaft of the drive motor. The tension wheel and the molecular sieve rotor are synchronously driven by a synchronous belt.

[0012] Preferably, the molecular sieve rotor has a dehumidification zone and a regeneration zone that are switched by rotation. The dehumidification unit also includes a regeneration fan, a regeneration housing, and a heating wire.

The heating wire is used to heat the air inside the regeneration housing, and the regeneration fan is used to blow the heated air through the regeneration zone.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. Because the five-constant system fresh air handling device of this utility model includes a condensing unit, a dehumidifying unit, and a humidifying unit, the condensing unit includes a condensing shell and a condensing coil, the condensing coil being connected to an air source heat pump, and the dehumidifying unit and the humidifying unit being selectively opened to the condensing shell through a two-position three-way valve, the dehumidifying unit includes a dehumidifying shell, a first guide fan, and a molecular sieve rotor. The first guide fan is used to make the airflow in the condensing shell and the dehumidifying shell form a unified dehumidification direction, and the molecular sieve rotor is positioned in the dehumidification direction. The humidifying unit includes a humidifying shell, a second guide fan, and a water-coated wet film, the second guide fan being used to make the airflow in the condensing shell and the humidifying shell form a unified humidification direction, and the water-coated wet film is positioned in the humidification direction. When the air source heat pump is running in cooling mode, the condensing shell is connected to the dehumidifying shell through the two-position three-way valve, and cold water flows through the condensing coil, cooling and condensing the external air flowing along the dehumidification direction to remove some moisture, and then removing some... Moisture-laden air continues to flow through the molecular sieve rotor in the dehumidification direction. The molecular sieve rotor adsorbs and regenerates moisture, achieving secondary moisture removal. This results in air exiting the dehumidification unit containing less moisture; the dehumidification effect of secondary moisture removal is significantly greater than the single-stage dehumidification effect of the molecular sieve rotor alone. When the air source heat pump operates in heating mode, the condenser shell is connected to the humidification shell via a two-position three-way valve. Hot water flows through the condenser coil, heating and evaporating the external air flowing in the humidification direction to increase its moisture content. This air, now with increased moisture content, continues to flow through the water-coated wet membrane in the humidification direction. The water-coated wet membrane again adsorbs and regenerates moisture, achieving a secondary increase in moisture content. This results in air exiting the dehumidification unit containing less moisture; the humidification effect of secondary moisture removal is significantly greater than the single-stage humidification effect of the water-coated wet membrane alone. Therefore, this invention can significantly improve the operating performance of both the dehumidification and humidification devices by reusing the heat energy of the air source heat pump without adding any hardware.

Detailed Implementation

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following embodiments, in conjunction with the accompanying drawings, specifically illustrate the fresh air treatment device for the five constant systems of this utility model. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.

[0020] like Figure 1 As shown, the fresh air handling device 100 for the five constant systems in this embodiment includes a condensation unit 10, a two-position three-way valve V, a communication module (not shown in the figure), a control module (not shown in the figure), a user terminal (not shown in the figure), a dehumidification unit 20, and a humidification unit 30.

[0021] The condensation unit 10 includes a condensation shell (not shown in the attached drawings) and a condensation tube assembly 11.

[0022] The condenser coil assembly 11 is fixed inside the condenser shell, and the condenser coil assembly 11 includes a condenser coil 111 and a condensate pan 112.

[0023] like Figure 2 As shown, the inner cavity of the condensate pan 112 is open upwards, the condensate coil 111 is hollow and its outer surface is continuous with the inner wall of the condensate pan 112, and the condensate coil 111 is connected to the outlet end of the external air source heat pump through the internal channel of the condensate pan 112 (not shown in the figure).

[0024] Both ends of the condenser coil 111 are connected to an external air source heat pump through the internal channels of the condensate pan 112. Thus, a fluid, which serves as a refrigerant or heat transfer medium, continuously flows into the condenser coil 111 from the air source heat pump, exchanging heat with the external airflow. The fluid that has undergone heat exchange in the condenser coil 111 finally flows back to the air source heat pump. Specifically, the outer surface of the casing 10 has two quick-connect connectors P. The air source heat pump has an outlet end (not shown in the attached figure) and a return end (not shown in the attached figure). The outlet end is connected to a quick-connect plug P, which is connected to one end of the condenser coil 111. The other end of the condenser coil 111 is connected to another quick-connect connector P, and the other quick-connect connector P is connected to the return end.

[0025] The dehumidification unit 20 includes a dehumidification housing (not shown in the figure), and the humidification unit 30 includes a humidification housing (not shown in the figure). Specifically, the condensation housing has a condensation inlet (not shown in the figure) and a condensation outlet (not shown in the figure) arranged opposite to each other, and the condensation inlet is used to introduce external airflow; the dehumidification housing has a dehumidification inlet (not shown in the figure) and a dehumidification outlet (not shown in the figure); the humidification housing has a humidification inlet (not shown in the figure) and a humidification outlet (not shown in the figure), and both the dehumidification outlet and the humidification outlet are open towards the room.

[0026] The dehumidification housing of dehumidification unit 20 and the humidification housing of humidification unit 30 are selectively opened to the condenser housing via a two-position three-way valve V. The control module is signal-connected to the two-position three-way valve V, and the communication module is signal-connected to the control module V. The user terminal is used to send a switching signal, and the communication module is used to receive the switching signal and transmit it to the control module. The control module is used to control the two-position three-way valve V to operate, thereby connecting the condenser outlet of the condenser housing to the humidification inlet of the humidification housing and the dehumidification inlet of the dehumidification housing. Specifically, the condenser outlet is connected to the input end of the two-position three-way valve V through a pipeline, and the dehumidification inlet and the humidification inlet are connected to the two output ends of the two-position three-way valve V through pipelines respectively. The user sends a switching signal through the user terminal by manually operating the user terminal, and controls the connection between the condenser housing and the dehumidification housing, and controls the connection between the condenser housing and the humidification housing through the switching signal, thereby forming a fresh air formation path from the outside airflow to the room.

[0027] The dehumidification unit 20 also includes a first guide fan 21, an internal support (not shown in the figure), a drive motor 22, a molecular sieve rotor 23, a regeneration cover 24, a regeneration fan 26, and a heating wire 27, all of which are disposed inside the dehumidification housing.

[0028] The first guide fan 21 is used to make the airflow in the condenser housing and the dehumidifier housing form a unified dehumidification direction D1. Specifically, when the two-position three-way valve V controls the connection between the condenser housing and the dehumidifier housing, a unified dehumidification direction D1 is formed in the condenser housing and the dehumidifier housing. In this embodiment, the first guide fan 21 is set at the dehumidification inlet, and the condenser coil 111 is blocked on the dehumidification direction D1. The dehumidification direction D1 is the fresh air formation direction.

[0029] The drive motor 22 and the molecular sieve rotor 23 are parallel to each other and rotatably mounted on the inner support of the shell. A tension wheel (not shown in the figure) is fixed on the output shaft of the drive motor 22. The circumference of the tension wheel and the circumference of the molecular sieve rotor 23 are synchronously driven by a synchronous belt (not shown in the figure), so that the drive motor 22 drives the molecular sieve rotor 23 to rotate.

[0030] like Figure 3 As shown, the molecular sieve rotor 23 is rotatably disposed inside the dehumidification housing and positioned in the dehumidification direction D1. The molecular sieve rotor 23 has a dehumidification zone 23a and a regeneration zone 23b that are cyclically converted by rotation. Specifically, in order to ensure the continuous use of the molecular sieve rotor 23, the molecular sieve rotor 23 should be evaporated and dehydrated after adsorbing moisture, so that the molecular sieve rotor 23 can return to a dry state. The positions of the dehumidification zone 23a and the regeneration zone 23b relative to the dehumidification housing 20 remain unchanged. The molecular sieve rotor 23 cyclically converts the dehumidification zone 23a and the regeneration zone 23b by rotation.

[0031] One end of the regeneration housing 24 is covered in the regeneration area 32, and the other end is open to the outside of the dehumidification housing. Specifically, the regeneration housing 24 is located between the molecular sieve rotor 23 and the dehumidification outlet.

[0032] The heating wire 27 and the regeneration fan 26 are both located inside the regeneration housing 24. The heating wire 27 is used to heat the air inside the regeneration housing 24, and the regeneration fan 26 is used to blow the heated air across the regeneration area 23b. Specifically, the air flows through the heating wire 27 and the regeneration fan 26 in sequence inside the regeneration housing 24, that is, the regeneration fan 26 is closer to the regeneration area 23b inside the regeneration housing 24.

[0033] Specifically, the dehumidification unit 20 also includes a dehumidification channel 25. The dehumidification channel 25 and the regeneration housing 24 are located on opposite sides of the regeneration area 23b. One end of the dehumidification channel 25 covers the regeneration area 32, and this end corresponds to the end of the regeneration housing 24. That is, the regeneration fan 26 blows hot air toward the regeneration area 32. The hot air evaporates the moisture in the regeneration area 23b containing moisture and blows it into the interior of the dehumidification channel 25. In this embodiment, the other end of the dehumidification channel 25 is open to the outside of the dehumidification housing, that is, the gas mixed with moisture is discharged to the outside of the dehumidification housing.

[0034] The humidification unit 30 also includes a second guide fan 31, a water-hanging wet film 32, a water inlet pipe 33, and a water collection tray 34, all of which are disposed inside the humidification housing.

[0035] The second guide fan 31 is used to make the airflow in the condenser housing and the humidifier housing form a unified humidification direction D2. Specifically, when the two-position three-way valve V controls the connection between the condenser housing and the humidifier housing, a unified humidification direction D2 is formed in the condenser housing and the humidifier housing. In this embodiment, the second guide fan 31 is set at the humidification inlet, and the condenser coil 111 is blocked on the humidification direction D2. The humidification direction D2 is the fresh air formation direction.

[0036] The inlet pipe 33, the wetted membrane 32, and the water receiving tray 34 are arranged vertically from top to bottom.

[0037] The water-retaining wet membrane 32 is installed in the humidification direction D2. Specifically, the water-retaining wet membrane 32 is a multi-layer membrane structure made of wet membrane material and is installed vertically.

[0038] The inlet pipe 33 is connected to an external water supply device (not shown in the attached figure). The inlet pipe 33 has multiple spray holes (not shown in the attached figure) arranged in a straight line along its length, and all spray holes face downwards and open towards the water-coated wet membrane 32.

[0039] Specifically, the lower part of the water tray 24 has a drain pipe 34a that opens toward the outside of the humidification housing. The drain pipe 34a is connected to the air source heat pump. In this embodiment, the drain pipe 34a is connected to the return end.

[0040] The above embodiments are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Various modifications or variations that can be made by those skilled in the art within the scope of the appended claims without creative effort are still within the scope of protection of this patent.
