Description
Technical Field
The invention relates to the technical field of fresh air systems, in particular to a fresh air system and a control method, a computer readable storage medium and a control device thereof.
Background
The working principle of the air conditioner is as follows: under the action of the indoor fan, a part of air in the indoor space is sucked into the shell through the air return opening and exchanges heat with the surface of the indoor heat exchanger, the temperature of the part of air is reduced/increased, then the part of air with the reduced temperature is sent into the indoor space through the air supply opening again, and the process is repeated, so that cold/heat generated by phase change and circular flow of the refrigerant can be gradually released into the indoor space. Although the conditioned air may satisfy the user's demand in terms of temperature, since the air in the indoor space is treated in the course of repeated cycles, the air quality of the indoor space tends to be degraded when the air conditioner is operated for a long duration.
In view of this, fresh air systems have appeared on the market in cooperation with air conditioners. The main function of the fresh air system is to exchange or partially exchange the air of the indoor space with the air of the outdoor environment, so as to update the air of the indoor space, namely to inject fresh air (fresh air) into the indoor space. Because the quality of the fresh air is directly determined by the outdoor environment, the fresh air needs to be pretreated, such as filtration and humidity control (dehumidification and/or humidification).
Taking the humidity control pretreatment including dehumidification and humidification of fresh air as an example, for example, the chinese patent (CN1768236C) discloses a humidity control device, and specifically discloses the following: a refrigerant circuit (1) is provided which is provided with a 1 st heat exchanger (3) and a 2 nd heat exchanger (5) and in which a refrigerant cycle performs a vapor compression refrigeration cycle. The adsorbents are respectively present on the surface of the 1 st heat exchanger (3) and the surface of the 2 nd heat exchanger (5). The refrigerant cycle and air circulation of the refrigerant circuit (1) are switched so that moisture of air flowing into the heat exchangers (3, 5) where the refrigerant evaporates is adsorbed by the adsorbent, moisture is released from air flowing into the heat exchangers (5, 3) where the refrigerant condenses, the adsorbent is regenerated, and the air dehumidified by the adsorbent is supplied to the room. The refrigerant cycle and the air circulation of the refrigerant circuit (1) are switched so that the moisture of the air flowing into the heat exchangers (3, 5) where the refrigerant evaporates is adsorbed by the adsorbent, the moisture of the air flowing into the heat exchangers (5, 3) where the refrigerant condenses is released, the adsorbent is regenerated, and the air humidified by the adsorbent is supplied to the room.
It can be seen that the document humidifies and dehumidifies the fresh air by configuring the compressor. However, the switching of the humidifying function and the dehumidifying function of the adsorbent is realized by switching of the four-way valve, and since the adsorbent needs to be periodically subjected to the adsorption and desorption operations, the periodic switching of the four-way valve is necessarily accompanied. For the same fresh air system, the humidification and dehumidification requirements are always selected and relatively fixed within a long time (only humidification is needed in winter in the north), meanwhile, the four-way valve is switched to require reversing pressure difference, corresponding noise cannot be avoided, and poor product experience is brought to users. Therefore, such periodic switching will result in the system not being able to operate continuously.
Accordingly, there is a need in the art for a new solution to the above problems.

Detailed Description
Some embodiments of the invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention.
It should be noted that the terms "first", "second", and the like in the description of the present invention are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. Furthermore, unless expressly stated or limited otherwise, the terms "connected" and "connected" are intended to be inclusive and mean, for example, that they may be directly connected or indirectly connected through intervening elements, or that they may be interconnected between two or more elements. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
The air conditioner mainly comprises a compressor forming a refrigerant main loop, an indoor heat exchanger, an outdoor heat exchanger, a throttling component (such as a capillary tube, an electronic expansion valve and the like) and a four-way valve, wherein the communication mode of the four-way valve is switched, so that the air conditioner can have a conventional refrigeration mode and a heating mode, and cold/heat can be distributed to the surface of the indoor heat exchanger along with the phase change of the refrigerant through the circulating flow of the refrigerant in a loop formed by the compressor, the condenser, the throttling component, the evaporator and the compressor. Specifically, the method comprises the following steps:
when the refrigerant circulates along the circuit of the compressor → the indoor heat exchanger → the outdoor heat exchanger → the compressor, the air conditioning system is in a heating cycle. In the case where the air conditioning system is in a heating mode, the indoor heat exchanger serves as a condenser that emits heat. Accordingly, under the action of the fan, air in the indoor space is sucked into the shell of the air conditioner to perform heat convection with the surface of the indoor heat exchanger so as to obtain heat during a heating cycle, and thus the temperature of the indoor space is increased.
When the refrigerant circulates along the circuit of the compressor → the outdoor heat exchanger → the indoor heat exchanger → the compressor, the air conditioning system is in a refrigeration cycle. Namely: in the case of an air conditioning system in a cooling mode, the indoor heat exchanger acts as an evaporator for distributing cooling energy. Accordingly, under the action of the fan, air in the indoor space is sucked into the shell of the air conditioner to perform heat convection with the surface of the indoor heat exchanger, so that cold energy is obtained during a refrigeration cycle, and the temperature of the indoor space is reduced.
Air conditioners generally comprise an outdoor part and an indoor part, which are integrated in the same casing for existing models (such as window air conditioners, etc.). For most models, the outdoor part and the indoor part are of a split structure, wherein the outdoor part is called an outdoor unit of an air conditioner, and the indoor part is called an indoor unit of the air conditioner, and the outdoor part and the indoor part are connected through a pipeline. Air conditioners of a split type structure generally include a cabinet type air conditioner, a wall-mounted air conditioner, and a built-in type air conditioner.
Taking an on-hook as an example, the back of a shell of an indoor unit of an air conditioner is usually fixedly arranged on a wall of an indoor space, an air return opening and an air supply opening are arranged on the shell, an indoor heat exchanger, an indoor fan, a water pan and the like are mainly arranged in the shell, and the indoor heat exchanger is mainly used for generating heat/cold on the surface of the shell along with the phase change of a refrigerant; the indoor fan mainly guides the air in the indoor space to enter the shell through the air return opening, exchanges heat with the indoor heat exchanger when flowing through the surface of the indoor heat exchanger so as to adjust the temperature of the air, and then sends the air to the indoor space again through the air supply opening; the water collector is mainly used for discharging condensed water outdoors during a refrigeration cycle, and specifically comprises: when the air conditioner is in a refrigerating cycle, the indoor heat exchanger as an evaporator transmits cold to an indoor space, and meanwhile, condensate water is generated on the surface of the indoor heat exchanger. The water receiving disc arranged below the indoor heat exchanger is mainly used for collecting condensed water generated on the surface of the indoor heat exchanger and timely discharging the condensed water out of the outdoor side, so that the operation sustainability of the air conditioner is guaranteed.
Since the air conditioner is operated during the cooling/heating cycle as described above, the air of the indoor space is constantly circulated to adjust the temperature and humidity thereof.

the air conditioner comprises a shell 100, and an indoor air supply outlet 11, an indoor air return inlet 12, an outdoor fresh air inlet 13 and an outdoor air outlet 14 which are arranged on the shell, wherein the indoor air supply outlet and the indoor air return inlet are communicated with an indoor space, and the outdoor fresh air inlet and the outdoor air outlet are communicated with an outdoor environment. If the casing is internally provided with an air duct which comprises a first air duct 21 and a second air duct 22, the upstream side of the first air duct is an outdoor fresh air inlet, and the downstream side of the first air duct is an indoor air supply outlet, so that fresh air of an outdoor environment is introduced into an indoor space through the first air duct, and the upstream side of the second air duct is an indoor air return inlet and the downstream side of the second air duct is an outdoor air outlet, so that air in the indoor space is discharged to the outdoor environment through the second air duct.
The indoor air supply opening is provided with an indoor fan 31, for example, an indoor fan is arranged in the air duct of the fresh air system at a position close to the upstream of the indoor air supply opening. So as to guide the fresh air from the outdoor fresh air inlet to be distributed to the indoor space. As will be understood from the following, the indoor fan of the present invention further includes: and in the internal circulation humidification/dehumidification mode, the air entering the fresh air system through the indoor air return opening is guided to be re-distributed back to the indoor space, and in the external circulation humidification/dehumidification mode, the fresh air from the outdoor fresh air opening is guided to be distributed to the indoor space.

So as to direct the air of the indoor space to be discharged to the outdoor environment. As will be understood from the following, the outdoor fan of the present invention further includes: in the internal circulation humidification/dehumidification mode, the fresh air entering the fresh air system through the outdoor fresh air inlet is guided to be directly discharged to the outdoor environment, and in the external circulation humidification/dehumidification and non-humidification/dehumidification air exchange states, the air in the indoor space is guided to be discharged to the outdoor environment.
The humidity control device mentioned in the background art performs humidification and dehumidification processing on fresh air by configuring a compressor. However, considering that the two factors of 'the adsorbent needs to be periodically adsorbed and desorbed' and 'the requirement of humidification and dehumidification is always one and relatively fixed for a long time', the document has the defects that the system cannot continuously operate and the problem of user discomfort caused by the switching of the four-way valve exists in practical application. On the basis of the above, the inventors have made earnest analyses and then have made the present invention.
The fresh air system of the invention also has the function of adjusting the air humidity on the premise of having the basic function of updating or partially updating the indoor space for circulating air. In addition, the fresh air system has the function of continuously humidifying/dehumidifying the air on the premise of realizing the air updating of the indoor space through the cooperation of the air channel, the adsorption material and the refrigerant circulating system.
With further reference to fig. 1 to 5, the fresh air system of the present invention comprises in particular:
1) the first switching mechanism is configured for the air duct of the fresh air system and has the following functions: the air duct of the fresh air system is switched from the first air duct and the second air duct to the third air duct 23 and the fourth air duct 24, wherein the upstream side of the third air duct is an indoor air return opening, and the downstream side of the third air duct is an indoor air supply opening, so that air introduced into the fresh air system from the indoor space is re-distributed to the indoor space through the third air duct, the upstream side of the fourth air duct is an outdoor fresh air opening, and the downstream side of the fourth air duct is an outdoor air exhaust opening, so that air introduced into the fresh air system from the outdoor environment is re-discharged to the outdoor environment through the fourth air duct.
It can be understood that, on the premise that the air duct of the fresh air system can be reasonably planned, a person skilled in the art can reasonably select a specific form of the first switching mechanism according to actual needs. For example, the air duct in the fresh air system can be switched to the aforementioned mode including the first air duct and the second air duct (referred to as a first mode) or the aforementioned mode including the third air duct and the fourth air duct (referred to as a second mode), for example, through a combination of a plurality of switchable dampers.
2) Dispose the humidity control unit in the wind channel, humidity control unit mainly includes the adsorption component who carries the adsorption material and drives the second switching mechanism that adsorbs the component motion, wherein:
21) the adsorbing member mainly comprises a first portion 41 and a second portion 42 which can be distinguished, for example, the first portion and the second portion are loaded with adsorbing materials which can be separated by corresponding structures and can be in different positions, for example, in the case that the first portion is in the second air channel, the second portion can be in the first air channel, and the like.
It is understood that a person skilled in the art can flexibly determine the specific structural forms of the first part and the second part and the combination form therebetween according to actual needs, for example, the structures of the two parts may be substantially the same, the two parts may be fixedly connected, integrally formed or be independent structures, and the like. As an example, the first portion and the second portion are symmetrical structures.
The basic properties of the adsorbent material are: the air conditioner can absorb moisture in the air flow passing through the air conditioner under normal conditions, and therefore the air conditioner can achieve the dehumidification effect. The moisture stored in the air conditioner can be released when the air conditioner is heated, such as the moisture is released into the air flow passing through the air conditioner, and therefore the air conditioner plays a role of humidifying. Illustratively, the adsorbent material may be one or more of silica gel, molecular sieve, zeolite, MOFs (Metal-Organic Frameworks), composite salts, and the like.
It can be understood that the higher the water absorption of the adsorbing material is, the higher the dehumidification efficiency is, so that a person skilled in the art can determine the specific composition of the adsorbing material according to the actual humidification and dehumidification requirements, such as the types of the materials, the mixture ratio among the types, and the amount of the materials; and the like. On the basis, a person skilled in the art can flexibly determine the carrying mode of the adsorption material according to actual requirements. As an example, the adsorbing member includes a substantially disk-shaped base body on which the adsorbing material is uniformly mounted over the entire area, and the base body is divided into two semicircular disks by a partition plate, one of the semicircular disks serving as the first portion and the other semicircular disk serving as the second portion.
22) The second switching mechanism is mainly used for driving the adsorption component to move, so that the first part and the second part can be located at different positions. If the second switching mechanism is a mechanism capable of driving the adsorbing member to rotate around the axis thereof, the mechanism may include, for example: the shell of the fresh air system is internally fixed with a motor, the adsorption component is fixed with a rotating shaft along the axial direction of the adsorption component, the power output end of the motor is connected with the rotating shaft, so that the adsorption component can be driven by the motor to rotate around the axial line of the adsorption component, and through rotation, the adsorption component can be positioned at a position (called as a first position) where the first part is positioned at the lower part and the second part is positioned at the upper part and the two parts are vertically arranged or at a position (called as a second position) where the first part is positioned at the left part and the second part.
It is to be understood that the switching between the vertical position and the horizontal position by the rotation of the suction member by the second switching mechanism constituted by the motor and the rotation shaft as described above is merely an exemplary description. Those skilled in the art can flexibly determine the specific form (structure, number, driving transmission principle, etc.) of the second switching mechanism, the specific form of the position (number of reachable positions, position of the adsorption member corresponding to each position, etc.) and the like according to actual requirements.
3) The refrigerant circulation part is configured for the adsorption component and comprises a first refrigerant circulation system and a second refrigerant circulation system which can independently operate, in fact, in the process of realizing the humidifying and dehumidifying functions of the invention, the first refrigerant circulation system and the second refrigerant circulation system are alternatively operated, specifically:
31) the first refrigerant cycle system includes a first compressor 51, a first heat exchanger, a second heat exchanger and a first throttling component 61, and under the action of the second switching mechanism, a first part of the adsorption component can exchange heat with the first heat exchanger, such as: the first portion and the first heat exchanger can be in the same duct (e.g., the second duct or the third duct) configured via the first switching mechanism, or preferably, at least a portion of the first portion can be aligned with the first heat exchanger while in the same duct to ensure a heat exchange effect, such that:
in the case where the first heat exchanger is a condenser, the first portion humidifies the passing air by absorbing heat and releasing moisture; and
in the case where the first heat exchanger is an evaporator, the first portion absorbs moisture to dehumidify the air flowing therethrough.
32) A second refrigerant circulation system including a second compressor 52, a third heat exchanger, a fourth heat exchanger and a second throttling part 62, wherein at least one part of the second part can be aligned with the third heat exchanger under the action of a second switching mechanism so as to: under the action of the second switching mechanism, the second part of the adsorption member can exchange heat with the third heat exchanger, such as: the second portion and the third heat exchanger can be in the same air duct (e.g., the first air duct or the fourth air duct) configured by the second switching mechanism, or preferably, at least a portion of the second portion can be aligned with the third heat exchanger when in the same air duct to ensure a heat exchange effect, so as to:
in the case where the third heat exchanger is a condenser, the second portion humidifies the passing air by absorbing heat and releasing moisture; and
in the case where the third heat exchanger is an evaporator, the second portion absorbs moisture to humidify the passing air.
In a possible embodiment, the first heat exchanger and the fourth heat exchanger are integrated, and the third heat exchanger and the second heat exchanger are integrated. The two heat exchangers arranged in unison are referred to as a first unified heat exchanger 71 and a second unified heat exchanger 72, respectively, each unified heat exchanger being a fin-tube heat exchanger and including two heat exchange sections, taking the first unified heat exchanger as an example, one heat exchange section of the fin-tube heat exchanger is used as a first heat exchanger and the other heat exchange section is used as a fourth heat exchanger. Similarly, one heat exchange part of the second heat exchanger is used as a third heat exchanger, and the other heat exchange part is used as a second heat exchanger.
Obviously, the unified configuration is only an exemplary description or a preferred embodiment, and it is obvious that a person skilled in the art can flexibly determine the specific configuration of the (first, second, third and fourth) heat exchangers according to actual situations, such as four independent heat exchangers, etc.
Still take the aforesaid unification setting as an example, the first unification heat exchanger sets up between indoor return air inlet and outdoor air exit, and the second unification heat exchanger sets up between indoor supply-air outlet and outdoor fresh air inlet. When the adsorption member is in a first position with the first part at the lower part and the second part at the upper part through the second switching mechanism, the first heat exchanger is just aligned with the first part, and the second heat exchanger is just aligned with the second part.
At this time, in the case where the air duct is switched to include the first air duct and the second air duct by the first switching mechanism, the first portion is located in the second air duct below, and the second portion is located in the first air duct above. Based on this, assuming that the first heat exchanger is a condenser, the first portion can humidify the air flowing through the second air passage.
The second switching mechanism rotates the suction member clockwise by 180 degrees, and the suction member is located at a second position where the first portion is located at the left and the second portion is located at the right. At this time, in the case where the air duct is switched to include the third air duct and the fourth air duct by the first switching mechanism, the first portion is located in the third air duct on the left side, and the second portion is located in the fourth air duct on the right side. Based on this, assuming that the second heat exchanger is a condenser, the second portion can humidify the air flowing through the fourth air duct.
Based on the fresh air system with the above structure, the process and principle of the fresh air system to achieve the continuous humidification and dehumidification function thereof will be further described with reference to fig. 2 to 5.
In the case of a north winter season or the like, in a bedroom or the like, there may be a case where the heating and the air conditioner in the heating mode are operated together. When the time is longer, the relative humidity of the air is obviously reduced, and in addition, the air (fresh air source) of the northern outdoor environment is drier, so that the air is necessary to be humidified, and at the moment, the fresh air system can be operated in a humidification mode, so that the air quality (basic function of the fresh air system) of the indoor space is ensured, and the air humidity (function of the fresh air system of the invention) of the indoor space is ensured. The humidifying mode comprises an external circulation humidifying mode and an internal circulation external circulation humidifying mode:
as shown in fig. 2, the implementation of the external circulation humidification mode specifically includes:
the second refrigerant circulating system is enabled to work, namely: the second compressor 52 is turned on, the second throttling part is operated 62, the fourth heat exchanger (one heat exchange portion of the first unified heat exchanger 71) at the lower left is an evaporator, and the third heat exchanger (one heat exchange portion of the second unified heat exchanger 72) at the upper right is a condenser. The adsorption member disposed between the (first and second) unified heat exchangers is brought to a first position by a second switching mechanism, that is: the first portion 41 is on the lower side and the second portion 42 is on the upper side and both are vertically arranged. Meanwhile, the air duct at the moment is in a first mode through a first switching mechanism, namely: the outdoor fresh air inlet 13 is communicated with the indoor air supply outlet 11 to form a first air duct 21, and the indoor return air inlet 12 is communicated with the outdoor air outlet 14 to form a second air duct 22.
The second part between the indoor air supply outlet and the outdoor fresh air outlet is aligned to the third heat exchanger serving as the condenser and is in the first air channel, so that the second part is in a desorption state of releasing moisture content due to heat absorption, namely, in an effective humidifying state. Since the first portion between the indoor return air inlet and the outdoor air outlet is aligned with the fourth heat exchanger as the evaporator, the first portion is in an adsorption state of absorbing moisture, i.e., a state of recovering the humidifying function.
Therefore, under the action of the indoor fan, fresh air in the outdoor environment enters the fresh air system through the outdoor fresh air inlet and enters the indoor space through the indoor air supply outlet through the first air channel. During this time, the fresh air is humidified while passing through the second portion between the outdoor fresh air port and the indoor supply air port. Meanwhile, air in the indoor space enters the fresh air system through the indoor air return opening and is exhausted to the outdoor environment through the outdoor air outlet through the second air duct. During this time, when the air passes through the first portion between the indoor return air inlet and the outdoor exhaust air outlet, the first portion absorbs moisture in the air, and the humidifying function is gradually restored.
It can be seen that in this case, the humidification function is realized with the feeding and discharging of fresh air, and thus this mode is referred to as an external circulation humidification mode.
As shown in fig. 3, the implementation of the internal circulation humidification mode specifically includes:
the first refrigerant circulating system is enabled to work, namely: the first compressor is turned on 51, the first throttle unit 61 is operated, the first heat exchanger (one heat exchange portion of the first unified heat exchanger 71) at the lower left is a condenser, and the second heat exchanger (one heat exchange portion of the second unified heat exchanger 72) at the upper right is an evaporator. The adsorption member disposed between the (first and second) unified heat exchangers is brought to a second position by a second switching mechanism, that is: the first section 41 is on the left, the second section 42 is on the right and both are arranged horizontally. Meanwhile, the air duct at the moment is in a first mode through a first switching mechanism, namely: the indoor return air inlet 12 is communicated with the indoor air supply outlet 11 to form a third air duct 23, and the outdoor fresh air inlet 13 is communicated with the outdoor air outlet 14 to form a fourth air duct 24.
Because the first heat exchanger as the condenser and the first part between the indoor air return opening and the indoor air supply opening are positioned in the third air duct, the first part is in a desorption state of releasing moisture content due to heat absorption, namely, in an effective humidification state. The second heat exchanger in the fourth air duct, in which the second part between the outdoor fresh air inlet and the outdoor air outlet is located, is used as an evaporator at this time, so that the second part is in an adsorption state of absorbing moisture, namely, a state of recovering a humidifying function.
Therefore, under the action of the outdoor fan, fresh air in the outdoor environment enters the fresh air system through the outdoor fresh air inlet and is exhausted to the outdoor environment space through the outdoor air outlet through the fourth air duct. During the period, when the fresh air flows through the second part between the outdoor fresh air inlet and the outdoor air outlet, the second part absorbs the moisture in the fresh air, and the humidifying function is gradually recovered. Meanwhile, air in the indoor space enters the fresh air system through the indoor air return opening and is re-distributed to the indoor space through the third air duct and the indoor air return opening. During this time, the air is humidified while passing through the first portion between the indoor return air inlet and the indoor supply air outlet.
In this case, the fresh air system is in operation, the humidification function of the second part is gradually restored, but fresh air is not introduced into the indoor space, and the humidification function is performed along with the discharge and introduction of air into the indoor space, so this mode is called an internal circulation humidification mode. This mode can also be explained as follows: the fresh air system is temporarily converted into an air conditioner with a humidifying function to humidify the air in the indoor space. During this time, however, the humidifying function of the second portion is restored.
Thus, when the user's demand is a humidification demand, the humidification function can be continuously realized while the basic function of introducing fresh air through the fresh air system only by periodically adjusting the mode of the air duct of the fresh air system through the first switching mechanism, periodically switching the relative positions of the first part and the second part in the adsorption member through the second switching mechanism, and enabling the (first and second) refrigerant circulation systems to correspondingly and alternately operate. The switching period of the adsorption member can be flexibly determined according to the attributes of the adsorption material, the actual humidification requirement, the service life of the adsorption material and other factors.
It is understood that the first switching mechanism is a combination of a plurality of switchable dampers, and the second switching mechanism includes a motor and a rotating shaft, which are only exemplary descriptions, and those skilled in the art can select any reasonable mechanism according to actual requirements on the premise that the mode switching of the air duct and the position switching of the suction member can be realized. Moreover, on the premise that switching can be realized without interference, the first switching mechanism and the second switching mechanism can be combined into a comprehensive mechanism, for example, the mechanism can be as follows: the mechanism comprises two integrated parts, one corresponding to the function of the first switching mechanism and the other to the function of the second switching mechanism; the mechanism has the functions of a first switching mechanism and a second switching mechanism at the same time; and the like.
On this premise, for example, a relative humidity threshold (low value) may be preset, and when the detected current relative humidity of the indoor space is less than the low value, the aforementioned humidification mode may be operated. In case the relative humidity reaches the target level (another relative humidity threshold higher than the low value), the humidification mode can be exited, i.e.: the refrigerant circulating system stops running, the air duct is switched to a certain reference mode, if the reference mode is the same as the first mode, the air duct at the moment comprises a first air duct and a second air duct, the adsorption member is located at the reference position, if the reference position is the same as the second position, the first part is located at the left part, the second part is located at the right part, and the first part and the second part are horizontally arranged.
Similar to the humidification function, when the air is required to be dehumidified, the fresh air system can be operated in a dehumidification mode, so that the air quality of the indoor space (the basic function of the fresh air system) is ensured, and the air humidity of the indoor space (the function of the fresh air system of the invention) is effectively reduced. The dehumidification mode includes an outer circulation dehumidification mode and an inner circulation dehumidification mode:
as shown in fig. 4, the external circulation dehumidification mode specifically includes:
the first refrigerant circulating system is enabled to work, namely: the first compressor is turned on 51, the first throttle unit 61 is operated, the first heat exchanger (one heat exchange portion of the first unified heat exchanger 71) at the lower left is a condenser, and the second heat exchanger (one heat exchange portion of the second unified heat exchanger 72) at the upper right is an evaporator. The adsorption member disposed between the (first, second) unified heat exchangers is in the first position by the second switching mechanism, i.e., the first portion 41 is on the lower side, the second portion 42 is on the upper side, and both are vertically arranged. Meanwhile, the air duct at the moment is in a first mode through a first switching mechanism, namely: the outdoor fresh air inlet 13 is communicated with the indoor air supply outlet 11 to form a first air duct 21, and the indoor return air inlet 12 is communicated with the outdoor air outlet 14 to form a second air duct 22.
Because the second part between the indoor air supply outlet and the outdoor fresh air outlet is aligned to the second heat exchanger serving as the evaporator, the second part can absorb and dehumidify fresh air flowing through the second heat exchanger. Since the first part between the indoor air return opening and the outdoor air exhaust opening is aligned with the first heat exchanger as a condenser, the first part releases the moisture stored therein into the air exhausted to the outdoor environment, and the water absorption and dehumidification functions of the first part are gradually restored.
Therefore, under the action of the indoor fan, fresh air in the outdoor environment enters the fresh air system through the outdoor fresh air inlet and enters the indoor space through the indoor air supply outlet through the first air channel. During the period, when the fresh air flows through the second part between the outdoor fresh air inlet and the indoor air supply outlet, the moisture in the fresh air is absorbed, the fresh air is dehumidified, and the first part is in an effective dehumidification state. Meanwhile, air in the indoor space enters the fresh air system through the indoor air return opening and is exhausted to the outdoor environment through the second air duct through the outdoor air outlet, during the period, when the air flows through the first part between the indoor air return opening and the outdoor air outlet, moisture stored in the first part is released, and the water absorption and dehumidification functions of the first part are gradually recovered.
It can be seen that in this case, the dehumidification function is performed with the feeding and discharging of fresh air, and thus this mode is referred to as an external circulation dehumidification mode.
As shown in fig. 5, the implementation of the internal circulation dehumidification mode specifically includes:
the second refrigerant circulating system is enabled to work, namely: the second compressor is turned on 52, the second throttling part 62 is operated, the third heat exchanger (one heat exchange portion of the second unified heat exchanger 72) at the upper right is a condenser, and the fourth heat exchanger (one heat exchange portion of the first unified heat exchanger 71) at the lower left is an evaporator. The adsorption member provided between the (first, second) unified heat exchangers is placed in the second position by the second switching mechanism, that is, the first portion 41 is on the left, the second portion 42 is on the right, and both are horizontally arranged. Meanwhile, the air duct at the moment is in a second mode through the first switching mechanism, namely: the indoor air return opening is communicated with the indoor air supply opening to form a third air duct 23, and the outdoor fresh air opening is communicated with the outdoor air outlet to form a fourth air duct 24.
Because the fourth heat exchanger as the evaporator and the first part between the indoor air return opening and the indoor air supply opening are positioned in the third air duct, the first part can absorb moisture in the air, and the air is dehumidified, namely the first part is in an effective dehumidification state. The third heat exchanger in the fourth air duct, where the second part is located between the outdoor fresh air inlet and the outdoor air outlet, is used as a condenser at the moment, so that the moisture stored in the second part is released, and along with the desorption process, the water absorption and dehumidification functions of the second part are gradually recovered.
Therefore, under the action of the outdoor fan, fresh air in the outdoor environment enters the fresh air system through the outdoor fresh air inlet and is exhausted to the outdoor environment through the outdoor air outlet through the fourth air duct. During the period, when fresh air flows through the second part between the outdoor fresh air inlet and the outdoor air outlet, the moisture stored in the second part is released, and the dehumidification function is gradually recovered. Meanwhile, air in the indoor space enters the fresh air system through the indoor air return opening and is re-distributed to the indoor space through the third air duct and the indoor air return opening. During this time, when the air passes through the first portion between the indoor return air inlet and the indoor supply air outlet, the first portion absorbs moisture in the air, and the air is dehumidified.
In this case, the fresh air system is in operation, the dehumidification function of the second part is gradually restored, but fresh air is not introduced into the indoor space, and the dehumidification function is performed along with the discharge and the introduction of air into the indoor space, so this mode is called an internal circulation dehumidification mode. This mode can also be explained as follows: the fresh air system is temporarily converted into an air conditioner with a dehumidification function to perform dehumidification treatment on the air in the indoor space. However, during this time, the dehumidification capacity of the second portion is restored.
Similar to the aforementioned requirements, in this way, when the user's requirement is a dehumidification requirement, the dehumidification function can be continuously realized while the basic function of introducing fresh air can be realized through the fresh air system only by periodically adjusting the mode of the air duct of the fresh air system through the first switching mechanism, periodically switching the relative positions of the first part and the second part in the adsorption member through the second switching mechanism, and correspondingly and alternately operating the (first and second) refrigerant circulation systems.
On this premise, for example, a relative humidity threshold (high value) may be preset, and when the current relative humidity of the detected indoor space is greater than the high value, the aforementioned dehumidification mode may be operated. In the case that the relative humidity reaches the target level (another relative humidity threshold lower than the high value), the dehumidification mode may be exited.
It can be seen that the fresh air system of the invention can realize four operation modes of an external circulation humidification mode, an internal circulation humidification mode, an external circulation dehumidification mode and an internal circulation dehumidification mode of the fresh air system through the combination of the mode switching of the air duct, the position switching of the adsorption component and the operation control of the refrigerant circulation system. Specifically, the fresh air system can be continuously in a state of realizing the humidification function or the dehumidification function by switching the configuration of the air duct between a first mode including the first air duct and the second air duct and a second mode including the third air duct and the fourth air duct by the first switching mechanism, switching the adsorption member between the first position and the second position by the second switching mechanism, and selectively setting the (first and second) refrigerant circulation systems to a fixed operating state by the second switching mechanism through cooperation of the three elements.
So far, the technical solution of the present invention has been described with reference to one embodiment shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Equivalent changes or substitutions of related technical features can be made by those skilled in the art without departing from the principle of the invention, and the technical scheme after the changes or substitutions can fall into the protection scope of the invention.
