Background
An air conditioner generally has a cooling mode and a heating mode, and cooling or heating energy is supplied to an indoor space by circulating a refrigerant through a loop formed by a compressor, a condenser, a throttling part (such as an electronic expansion valve or a capillary tube, etc.), an evaporator, and a compressor, thereby reducing or increasing a temperature of the indoor space. The switching between the cooling mode and the heating mode is performed by switching the four-way valve. Specifically, the flow path of the refrigerant in the loop is switched through the four-way valve, so that: when the air conditioner is in a cooling mode, the indoor heat exchanger is an evaporator and the outdoor heat exchanger is a condenser, and when the air conditioner is in a heating mode, the indoor heat exchanger is a condenser and the outdoor heat exchanger is an evaporator.
If the air conditioner is in the cooling mode and the heating mode for a long time, since air of the indoor space is always circulated, air quality is deteriorated. In view of this, air conditioners with an additional fresh air module are now available. The fresh air module mainly introduces air of an outdoor environment into an indoor space, so that the air quality is improved in a mode of partially replacing and updating the circulated air by using the indoor space.
When fresh air is introduced through the fresh air module, under the condition that the function of introducing the fresh air and the refrigeration/heating function are independently realized (for example, the refrigeration/heating function is temporarily sacrificed in the process of introducing the fresh air), certain influence is exerted on the user experience of the indoor space.
Accordingly, there is a need in the art for a new solution to the above-mentioned problems.
Disclosure of Invention
Technical problem

A first aspect of the present invention provides a combined control method for an air conditioning module, where the air conditioning module includes an air conditioner capable of adjusting a temperature of indoor air and a fresh air blower capable of exchanging outdoor air with the indoor air, the fresh air blower includes a first air duct, a second air duct, and a heat exchange core body belonging to the first air duct and the second air duct, the first air duct is configured with a first fan so that outdoor air of an outdoor environment is introduced into an indoor space through the first air duct by the first fan, and the second air duct is configured with a second fan so that indoor air of the indoor space is introduced into the outdoor environment through the second air duct by the second fan, the combined control method includes: detecting an outdoor temperature in a case where the air conditioner is in a cooling mode; and under the condition that the outdoor temperature is not higher than the set temperature, starting the first fan and the second fan.
Through such setting, can prevent effectively that the phenomenon that results in the refrigeration effect to worsen owing to introduce the new trend. For example, the set temperature may be a higher value, such as 30 ℃.
It should be noted that, a person skilled in the art may select the starting time of the first fan and the second fan, the respective operation mode, and the like according to the actual situation, as long as it is ensured that the air exchange amount is approximately the same. As an example, the first fan and the second fan are regularly the same, are turned on simultaneously, and are operated in a consistent manner.
In a possible embodiment, the "turning on the first fan and the second fan in case that the outdoor temperature is not higher than the set temperature" includes: detecting the indoor temperature under the condition that the outdoor temperature is not higher than the set temperature; and under the condition that the indoor temperature does not reach the target temperature, starting the first fan and the second fan.
Through such setting, can guarantee that the indoor space can obtain the higher air of quality under the situation that the temperature is up to standard.
Specifically, in the operation process of the air conditioning assembly, the air exchanger serves as the auxiliary of the air conditioner, and the air conditioner can actively improve the air quality while refrigerating according to the requirements of users. Thus enabling users of the indoor environment to obtain air of up-to-standard temperature and improved quality.
In one possible embodiment, the "turning on the first fan and the second fan in case that the indoor temperature does not reach the target temperature" includes: determining the falling speed of the indoor temperature; and under the condition that the descending speed is greater than the set speed, at least reducing the rotating speed of the first fan.
Through such setting, through the mode that reduces the outdoor air that will introduce in time, reduced the degree that the refrigeration experience of indoor space receives the influence because introduce too much outdoor air as far as possible.
It should be noted that the set speed is usually a small value, and the set speed may be a negative value, that is, when too much outdoor air is introduced into the indoor space, the temperature of the indoor air may be increased. Typically, the set speed is a value between-3 and 3 deg.C, such as-1 deg.C.
It will be appreciated that the reduction in the speed of the first fan may be a continuous reduction, a stepped reduction, or the like. In addition, under the premise of reducing the introduced amount of the outdoor air, the same amount of discharged indoor air does not need to be ensured synchronously. Such as may be: the rotating speed of the first fan is reduced in a two-stage step mode, and the rotating speed of the second fan is approximately kept unchanged.
In one possible embodiment, the "reducing the rotation speed of at least the first fan in the case that the descending speed is greater than the set speed" includes: reducing the rotating speed of the first fan under the condition that the descending speed is greater than a set speed; and enabling the rotating speed of the second fan to be consistent with the rotating speed of the first fan.

By means of the arrangement, a regulating strategy for enabling the rotating speed of the fan close to the indoor side to be different from that of the fan close to the outdoor side is provided.
It is understood that the second fan operating at intervals in sections of rotational speed may be: operating the corresponding time segments at different fixed rotation speeds; the fixed rotating speed is adopted in some time sections, and the variable rotating speed is adopted in some time sections, namely, further rotating speed regulation is included in a certain time section; the rotation speed of a certain section is zero, namely the machine is stopped in the time section.
In one possible embodiment, the "turning on the first fan and the second fan in case that the indoor temperature does not reach the target temperature" includes: and under the condition that the outdoor temperature is lower than the indoor temperature, increasing the rotating speed of the first fan.
With such an arrangement, the achievement of the cooling effect is promoted in a manner of maximizing the "ready" low-temperature wind.
In a possible embodiment, the method for jointly controlling the air conditioning components includes that the fresh air machine is provided with a third air duct, an upstream side of the third air duct is communicated with the indoor space, a downstream side of the third air duct is communicated with the first air duct, an upstream side of the third air duct is provided with a bypass damper, and the step of turning on the first air machine and the second air machine when the indoor temperature does not reach the target temperature includes: and in the case that the outdoor temperature is lower than the indoor temperature, opening the bypass damper.
Through the arrangement, in the process of increasing the 'ready' low-temperature wind, the air in the indoor space is introduced, so that the temperature change is softer, and the phenomenon of cold shock in the experience of a user in the indoor space caused by the rapid introduction of the 'ready' low-temperature wind and the over-quick temperature reduction is avoided.
With regard to the above-mentioned combined control method for an air conditioning assembly, in one possible embodiment, the air conditioning assembly further includes a humidity adjustment module, and the control method includes: under the condition that the indoor temperature does not reach the target temperature and the difference value between the indoor temperature and the target temperature is reduced to a set temperature difference value, a humidity adjusting module is started to adjust the humidity of the air in the indoor space; or the step of turning on the first fan and the second fan when the indoor temperature does not reach the target temperature comprises: opening a humidity adjusting module to adjust air of the indoor space; the difference between the humidity of the air in the indoor space and the target humidity is reduced to a set humidity difference, and the indoor temperature does not reach the target temperature, the first fan and the second fan are started.
With this arrangement, two schemes are given. One is a temperature and humidity combined regulation scheme with temperature priority. Typically, the temperature difference is set to a value between 2-5 deg.C (e.g., 2 deg.C). The other is a temperature and humidity combined regulation scheme with priority on humidity. Typically, the humidity difference is set to a value not greater than 10% (e.g., 5%).
It should be noted that, for users of indoor spaces, the demand for temperature rise mainly varies in winter and the demand for cooling in summer, and the demand for cooling varies depending on air conditions and users. As in the case of the same air conditions, the moisture content is not favorable for sweat evaporation, and some users feel discomfort. Although refrigeration necessarily reduces humidity, it may be that in some cases, the reduction in humidity from a simple refrigeration process is not desirable to the user.
Since the cooling requirement is related to both temperature regulation and humidity regulation, the present invention provides the two adjustment schemes based on humidity priority and temperature priority, respectively.
In a second aspect, the present invention provides an air conditioning assembly comprising a control module, wherein the control module is configured to execute the combined control method of the air conditioning assembly according to any one of the preceding claims.

Detailed Description
Preferred embodiments of the present 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 protection of the present invention and the like.
It should be noted that in the description of the present invention, the terms of direction or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings, which are only for convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
Referring to fig. 1, fig. 1 is a schematic view illustrating a structure of an air conditioning assembly according to an embodiment of the present invention. As shown in fig. 1, the air conditioning assembly 100 mainly includes an air conditioner 1, a fresh air blower 2 and a humidification degree adjusting module 3, wherein the air conditioner is mainly used for adjusting air temperature, the fresh air blower is mainly used for introducing fresh air, and the humidification degree adjusting module emphasizes on adjusting air humidity.
The air conditioner 1 generally includes an outdoor unit and an indoor unit (for example, in the case of a window machine, the indoor unit and the outdoor unit are physically integrated into an integrated machine, and pipes connecting the outdoor unit and the indoor unit are also integrated into an integrated machine at the same time, whereas in the case of a general machine type such as a cabinet machine, a suspended ceiling machine, etc., the outdoor unit and the indoor unit are generally disposed in a split design in which the outdoor space and the indoor space are respectively disposed, and pipes connecting the outdoor unit and the indoor unit are disposed through a wall, the outdoor unit mainly includes a compressor, an outdoor fan, and an outdoor heat exchanger (usually referred to as a condenser), the indoor unit mainly includes an indoor heat exchanger (usually referred to as an evaporator), an indoor fan, an electric cabinet, etc., and the compressor-condenser-evaporator-compressor forms a circulation circuit of a refrigerant. When the refrigerant circulates along the compressor → the outdoor heat exchanger → the indoor heat exchanger → the compressor, the air conditioner is in a refrigerating cycle. When the refrigerant circulates along the compressor → the indoor heat exchanger → the outdoor heat exchanger → the compressor, the air conditioner is in a heating cycle.
It can be seen that the air conditioner adjusts the temperature of the air in the indoor space during the cooling mode or the heating mode according to the following principle: under the action of the indoor fan, air in the indoor space is sucked into the shell through the air inlet (such as an air inlet grille), and after convective heat exchange is carried out between the air and the surface of the indoor heat exchanger in the shell (the indoor heat exchanger is a condenser in function in a heating mode, so the air absorbs heat and is heated, and the indoor heat exchanger is an evaporator in a cooling mode, so the air releases heat and is cooled), the air is sent into the indoor space through the air outlet. The casing is usually provided with a flap, an air guide plate, and the like at a position corresponding to the air outlet for adjusting the air outlet direction. Since the air in the indoor space is always circulated and conditioned during the temperature conditioning process, and as a general knowledge, the air conditioner should maintain the indoor space in a closed state as much as possible during the cooling and heating operation, the air quality is reduced after the air conditioner is continuously operated for a long time. At this time, the air quality of the indoor space can be improved by introducing air (fresh air) of the outdoor environment into the indoor space, and the fresh air fan 2 is configured accordingly.
The fresh air machine 2 is a fresh air and exhaust ventilation device containing a heat exchange core body, and is mainly used for preheating or precooling fresh air introduced into a room by recovering waste heat in exhaust, and reducing (increasing) the enthalpy value of the fresh air before the fresh air enters the room or a surface cooler of an air conditioner for heat-moisture treatment.
The humidity adjusting module 3 may be an independent module (such as a humidifier), or may be configured by setting a pipeline of the air conditioner and a pipeline switching mechanism, and by planning a refrigerant circuit, the air conditioner may implement a corresponding humidity adjusting function when corresponding to the set refrigerant circuit.
Referring to fig. 2, fig. 2 is a schematic structural diagram of a fresh air machine in an air conditioning assembly according to an embodiment of the present invention. As shown in fig. 2 and according to the orientation in fig. 2, the new air blower 2 includes a housing, a first air duct 211, a second air duct 212 and a heat exchange core 22 belonging to the first air duct and the second air duct, the first fan 231 is disposed on the downstream side of the first air duct, i.e., on the upper right side in the figure, so as to introduce the outdoor air of the outdoor environment into the indoor space through the first air duct by the first fan, and the second fan 232 is disposed on the downstream side of the second air duct, i.e., on the upper left side in the figure, so as to introduce the indoor air of the indoor space into the outdoor environment through the second air duct by the second fan.
When the fresh air machine works, a first air channel corresponding to fresh air introduction and a second air channel corresponding to indoor exhaust flow through the heat exchanger core in a crossed (heat exchange) but non-interference (unmixing) mode, and because the air flow at the two sides of the air flow partition plate has temperature difference and steam partial pressure difference, the heat transfer and mass transfer phenomena are generated when the two air flows pass through the partition plate, so that the total heat exchange process is caused. If the fresh air machine runs in the refrigeration mode in summer, the fresh air obtains cold energy from indoor exhaust air, the temperature is reduced, meanwhile, the fresh air is dried by the indoor exhaust air, and the moisture content is reduced. When the air conditioner operates in a refrigeration mode in winter, the fresh air obtains heat from indoor exhaust air, and the temperature rises. Therefore, through the total heat exchange process of the heat exchange core, effective energy can be recovered from indoor exhaust air of the air conditioner in the process of introducing fresh air.
As a modification, a third air duct (not shown) is further provided on the fresh air machine, specifically, an upstream side of the third air duct communicates with the indoor space, a downstream side of the third air duct communicates with the first air duct, and an upstream side of the third air duct is provided with a bypass damper. Therefore, under the condition that the side ventilation door is opened, the air in a part of the indoor space can be introduced into the first air channel, mixed with fresh air and then sent into the indoor space.
The situations in which fresh air needs to be introduced mainly include the following two situations:
one is the case where there is no need to adjust the temperature of the indoor space (e.g., there is no cooling or heating requirement because the ambient temperatures inside and outside are approximately the same), and the air quality of the indoor space can be improved by only operating the fresh air blower. Because the air conditioner does not need to introduce a heat exchange mechanism at the moment, the operation parameters of the fresh air part can be firstly increased and stabilized to the highest gear corresponding to the target operation parameters, and the fresh air part is closed after being operated for a certain time (such as 30 min) in the state.
The other is the situation that the temperature of the indoor space needs to be adjusted (for example, the indoor environment and the indoor environment have different temperatures, so that the indoor environment and the outdoor environment have refrigerating and heating requirements), and the air of the indoor space is improved through the combined operation of a fresh air fan and a heat exchange mechanism of an air conditioner. Under this kind of situation, in order to prevent that the temperature variation that the new trend that outdoor environment introduced from bringing from resulting in the heat transfer mechanism of air conditioner to receive the influence and then influence user experience, after new trend machine steady operation, should be according to its operation mode of adjustment of heat transfer mechanism. Such as may be: the operating parameters of the fresh air machine are first raised and stabilized to the highest gear corresponding to the target operating parameters, and theoretically, the fresh air machine should be operated in this state for a certain time (e.g., 15 min). However, when the temperature difference between the current indoor temperature and the target temperature corresponding to the heat exchange mechanism is 5-10 ℃, the operation gear of the fresh air fan is adjusted downwards, and when the temperature difference between the current indoor temperature and the target temperature corresponding to the heat exchange mechanism is more than 10 ℃, the fresh air part is closed no matter whether the temperature difference reaches 15min or not.
The invention mainly aims at the second situation, in particular to the situation that the air conditioner is in a refrigeration mode, and improves the user experience of the indoor space by carrying out combined control on the air conditioner, the fresh air fan and the humidity adjusting module.
It can be understood that, on the premise of ensuring the function implementation, the physical configuration form, arrangement mode, etc. of the three parts may be flexibly set, for example, the three parts may be separately set, or some or all of them may be appropriately integrated. The present embodiment takes the three parts of the air conditioning assembly as an example, and the three parts are not associated with each other in physical orientation, and obviously, this is only an exemplary description, for example, the relative positions of the parts can be associated to some extent, for example, a new fan can be arranged upstream of the air conditioner, etc.
Based on the structure, the air conditioning assembly further comprises a control module, and the following control method can be performed on the air conditioning assembly through the control module, so that the experience of a user in an indoor space is improved under the condition that fresh air needs to be introduced into the indoor space through the air conditioning assembly.
In the description of the present invention, a "module" or "processor" may include hardware, software, or a combination of both. A module may comprise hardware circuitry, various suitable sensors, communication ports, memory, may comprise software components such as program code, or may be a combination of software and hardware.

Referring to fig. 3, fig. 3 is a flowchart illustrating a combined control method of an air conditioning assembly according to an embodiment of the present invention. As shown in fig. 3, the combined control method of the air conditioning assembly includes the steps of:
s31, detecting the outdoor temperature under the condition that the air conditioner is in a refrigeration mode;
and S32, starting the first fan and the second fan under the condition that the outdoor temperature is not higher than the set temperature and the indoor temperature does not reach the target temperature.
In this embodiment, the set temperature is 30 ℃, the first fan and the second fan are synchronously started and run at a preset reasonable rotation speed, and the running parameters are synchronously adjusted all the time after the first fan and the second fan are started.
With this arrangement, it is possible to provide higher quality air to the user of the indoor space while preventing the cooling effect from being reduced as much as possible.
Generally, during the process of introducing fresh air, the drop speed of the indoor temperature is slowed down but still maintains a trend of dropping, and then:
and S33, determining the descending speed of the indoor temperature, jumping to S34 under the condition that the descending speed is greater than the set speed, and keeping the current rotating speed to continue running under the condition that the descending speed is less than or equal to the set speed.
As in the present example, the descent rate was 1 ℃/min.
And S34, reducing the rotating speed of the first fan and synchronously adjusting the rotating speed of the second fan.
As in one possible embodiment, the decrease in the rotational speed of the (first, second) fan may be adjusted in accordance with the decrease speed of the indoor temperature in a PID adjustment manner. It is clear that this is only an exemplary description and that a person skilled in the art may also adjust the speed reduction of the (first, second) fan in other existing or specifically established ways. Such as may be: the rotation speeds of the (first and second) fans include some fixed rotation speeds, and are adjusted in a mode that the rotation speeds are reduced in a stepped mode and the rotation speed of a single fan is reduced to be reduced by one step only under the condition that the rotation speeds of the (first and second) fans are required to be reduced.
In summer, during the process of introducing fresh air, the outdoor temperature is usually higher than the indoor temperature, however, assuming that the outdoor temperature is lower than the indoor temperature, the process of introducing pure fresh air is also substantially a process of reducing the indoor temperature, therefore, the combined control method may further include the following steps:
and under the condition that the outdoor temperature is lower than the indoor temperature, the rotating speed of the first fan is increased.
In the process of introducing the ready-made low-temperature fresh air, the increase of the rotating speed is accompanied by the concentrated input of the cooling capacity, which may cause a user in the indoor space to feel cold shock.
Meanwhile, the combined control method of the air conditioner component also comprises the step of humidity adjustment, and specifically comprises the following steps:
and under the condition that the indoor temperature does not reach the target temperature and the difference value between the indoor temperature and the target temperature is reduced to the set temperature difference value, the humidity adjusting module is started to adjust the humidity of the air in the indoor space. As in the present embodiment, the set temperature difference is taken to be 2 ℃.
It can be seen that, in the technical solution of this embodiment, on the premise that the user selection of the indoor space is temperature priority, in the process of adjusting the temperature of the indoor air by the air conditioner, the fresh air fan exchanges the outdoor air with part of the indoor air, thereby improving the quality of the indoor air. Through control to air interchange and humidity control, promoted the user's of indoor space experience. Particularly, the freshness of the air is improved on the basis of ensuring that the user can expect air of temperature and humidity.
It should be noted that, although the foregoing embodiments describe each step in a specific sequence, those skilled in the art may understand that, in order to achieve the effect of the present invention, different steps do not have to be executed in such a sequence, and may be executed simultaneously or in other sequences, and some steps may be added, replaced or omitted, and these changes are within the protection scope of the present invention.
It should be noted that, although the control method configured as described above is described as an example, those skilled in the art will appreciate that the present invention should not be limited thereto. In fact, the user can flexibly adjust the relevant steps, parameters in the steps and other elements according to the situations such as actual application scenes and the like.
So far, the technical solutions of the present invention have been described in connection with the preferred embodiments 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.
