Description
Technical Field
The application relates to the technical field of electric appliances, in particular to a fresh air cabinet control method and device, a fresh air cabinet and a storage medium.
Background
With the development of air conditioning technology, more and more air conditioners and fresh air cabinets have a dehumidification mode for reducing humidity in the environment. The specific principle is that when high-temperature air with vapor in the environment such as a room flows through the low-temperature evaporator radiating fins of the air conditioner, the temperature of the air reaches below the dew point temperature due to the cooling effect of the evaporator, and at the moment, part of the vapor in the air can be condensed into water to be separated out, so that the aim of dehumidification is fulfilled.
In general, the dehumidifying operation of an air conditioner is not like the cooling operation of an air conditioner, and air cannot quickly pass through the radiating fins of the evaporator, because if the air is fast, water vapor is not condensed and returns to the room. The indoor fan is generally operated at a slow speed when the dehumidifying operation is performed, so that moisture in the air is sufficiently condensed. That is, the air conditioner dehumidifies to lower the air temperature, and thus also to lower the indoor temperature.
Although the compressor responsible for cooling is not continuously operated in the dehumidified state, it intermittently dehumidifies, so that the temperature in the room is lowered less severely than that of direct cooling. However, in some special environments or scenes, such as a plum rain season or a cool and humid environment, the indoor temperature of the existing room air conditioner is obviously reduced during the dehumidification operation, so that the environmental comfort is greatly reduced. Thus, there is a need for a method that can maintain constant indoor temperature comfort while dehumidification is being performed.

Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail below. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, based on the examples herein, which are within the scope of the application as defined by the claims, will be within the scope of the application as defined by the claims.
Method embodiment:
fig. 1 is a flow chart of a method for controlling a fresh air cabinet according to an embodiment of the present application, as shown in fig. 1, the method at least may include:
s101, in a dehumidification mode, detecting the indoor temperature.
Specifically, in the method for controlling the fresh air cabinet provided by the embodiment of the application, when the fresh air cabinet is in the dehumidification mode, the detection of the ambient temperature such as the indoor temperature is started, and the real-time detection can be performed through the ambient temperature sensing bag arranged on the indoor unit, for example, the indoor temperature is continuously detected based on the preset frequency or the frequency selected by the user until the fresh air cabinet is in other modes, and the detection of the indoor temperature is stopped.
S102, if the indoor temperature is lower than a preset threshold value, the first air inlet pipeline is conducted.
S103, running a fresh air system.
Specifically, the first air inlet pipeline is used for supplying air for a fresh air system of the fresh air cabinet. In the embodiment of the application, the first end of the first air inlet pipeline is communicated with the fan cavity of the air conditioner external unit of the fresh air cabinet, and the second end of the first air inlet pipeline is communicated with the air inlet of the fresh air system of the fresh air cabinet.
It will be appreciated that the temperature of the air in the fan chamber of the air conditioner is typically relatively high as the dehumidification operation is performed, including compressor operation and the like. The fresh air system can transfer and release the air at one end of the air inlet pipeline to the room, so when the fresh air system of the fresh air cabinet is in an operation state and the first air inlet pipeline is in a conducting state, the hot air in the fan cavity of the air conditioner external unit can enter the room through the first air inlet pipeline and the fresh air system, and the indoor temperature is improved.
The application provides a fresh air cabinet control method, which comprises the following steps: in a dehumidification mode, detecting an indoor temperature; if the indoor temperature is lower than a preset threshold value, a first air inlet pipeline is conducted, wherein the first end of the first air inlet pipeline is communicated with an air conditioner external fan cavity of the fresh air cabinet, and the second end of the first air inlet pipeline is communicated with an air inlet of a fresh air system of the fresh air cabinet; and the fresh air system is operated so that a hot air port in a fan cavity of the air conditioner external unit enters the room through the first air inlet pipeline and the fresh air system. So, in the dehumidification process, when the indoor temperature is lower because of dehumidification, can improve indoor temperature through introducing the indoor with the hot air of the indoor fan intracavity of air conditioner to avoid the dehumidification to lead to indoor temperature to reduce seriously, guarantee indoor temperature's travelling comfort.
In some embodiments of the present application, hardware changes may be performed on an existing fresh air cabinet, for example, a control device (including a control module and other necessary modules and devices, such as a pipeline, etc.) for implementing the functions of the foregoing method is added, so as to implement the control method provided in the embodiments of the present application, and achieve the purpose of ensuring indoor temperature comfort in a dehumidification mode.
Because the fresh air cabinet machine can be in other modes such as a fresh air mode and the like besides dehumidification in a dehumidification mode, and in other modes, the temperature does not need to be regulated and controlled, or the temperature does not need to be regulated and controlled through the method, in some embodiments of the application, a plurality of air inlet pipelines can be arranged for the fresh air cabinet machine and used for respectively acquiring air from different areas so as to meet different requirements of the fresh air cabinet machine in different modes. Fig. 2 is a schematic diagram of a method for controlling a fresh air cabinet according to an embodiment of the present application, and as shown in fig. 2, a device for controlling a fresh air cabinet according to an embodiment of the present application for implementing or applying the method for controlling a fresh air cabinet may include a first air intake duct 1 and a second air intake duct 2.
Specifically, as mentioned in the above embodiment, the first air inlet pipe 1 may be that the first end is communicated with the fan cavity of the air conditioner external unit of the fresh air cabinet, and the second end is communicated with the air inlet of the fresh air system of the fresh air cabinet. The air conditioner external fan cavity can comprise an external fan and other devices for discharging the hot air preheated by the compressor and condensation heat of an external heat exchanger condenser and the like to the outside. Therefore, in the dehumidification mode, when the indoor temperature is too low, hot air can be acquired through the first air inlet pipeline, and then the hot air is transferred and released indoors through the fresh air system, so that the indoor temperature is regulated, and the condition that the indoor temperature is too low due to dehumidification is avoided.
Meanwhile, in the embodiment of the application, a second air inlet pipeline 2 can be further arranged, the first end of the second air inlet pipeline 2 is directly communicated with the outside, the second end of the second air inlet pipeline 2 can be identical to the second end of the first air inlet pipeline 1, and the second end of the second air inlet pipeline 2 can be communicated with an air inlet of a fresh air system. Therefore, under the control of the control module in other modes such as a fresh air mode, the first air inlet pipeline 1 can be blocked, the second air inlet pipeline 2 can be opened, and daily common fresh air operation can be performed.
In other embodiments, since the existing fresh air cabinet has the air inlet pipe communicated with the outdoor, the function of the second air inlet pipe 2 in the above embodiment of the present application may be implemented by the air inlet pipe of the existing fresh air cabinet, that is, the control device may not separately provide the second air inlet pipe 2.
It should be noted that, in the above embodiment, when the first air inlet pipe 1 is turned on in the dehumidification mode and the indoor temperature is lower than the preset threshold, the second air inlet pipe 2 is blocked, so that the temperature entering the room through the fresh air system is higher, and the indoor temperature regulation efficiency is improved. The conducting state of the first air inlet pipeline 1 and the second air inlet pipeline 2 can be realized by connecting a switch module with a control module.
In addition, in the embodiment of the application, because the indoor temperature is not lower than the preset threshold value in the dehumidification mode, namely the indoor temperature is higher than or equal to the preset threshold value, and the indoor temperature is still in the comfortable temperature range, the hot air in the fan cavity of the air conditioner external unit is not required to be introduced into the indoor, so that the fresh air system can be closed under the condition, and the energy saving effect is realized.
Further, in some embodiments of the present application, when the temperature adjustment is required (i.e., the fresh air cabinet is in the dehumidification mode and the indoor temperature is lower than the preset threshold), the operation states of other components of the fresh air cabinet may be adjusted to further improve the efficiency of temperature adjustment.
For example, the frequency of the compressor of the cabinet air conditioner can be increased to increase the heat generated by the compressor, so that the temperature of the air in the fan cavity of the air conditioner external unit can be rapidly increased. And the rotating speed of the external machine fan of the fresh air cabinet machine can be reduced, so that the amount of hot air in the cavity of the external machine fan of the air conditioner discharged to the outside by the external machine fan is reduced, the hot air in the cavity of the external machine fan of the air conditioner can enter a room through the first air inlet pipeline 1 and the fresh air system, the indoor temperature can be improved, the indoor temperature can not be too low due to dehumidification, and the indoor comfort is improved.
Further, in some embodiments of the present application, after the hot air in the fan chamber of the air conditioner external unit is introduced into the room through the first air intake duct 1 and the fresh air system, the hot air may be mixed with the air, such as cool air, which is originally discharged into the room in the dehumidifying mode, of the indoor unit, and then the mixed air is discharged into the room again. For example, an air deflector 3 may be disposed at a fresh air supply port of the fresh air system of the indoor unit to control the flow direction of the fresh air, so that the fresh air (such as hot air in a fan cavity of the outdoor unit of the air conditioner) and the cooling air (the air that the indoor unit originally needs to exhaust to the indoor in the dehumidification mode) are converged, thereby improving the air outlet temperature of the fresh air cabinet, that is, the air conditioner. Therefore, the difference of the temperature of the indoor local areas caused by the fact that hot air and cold air are respectively discharged is avoided, and the indoor temperature comfort is further improved. Fig. 3 is a schematic structural diagram of an inner unit portion of a fresh air cabinet according to an embodiment of the present application, where specific hardware configuration may be as shown in fig. 3 ， Fresh air (such as hot air in a fan cavity of an air conditioner external unit) can enter the internal unit from the position A, is guided by the air guide plate 3 from the position B of a fresh air outlet, and is converged and discharged with refrigerating air (air which is originally discharged to the room in a dehumidification mode by the internal unit) discharged from the air outlet C of the internal unit at the position D.
Of course, for some special environments (such as a larger indoor area or a special area), in other embodiments of the present application, the hot air may be directly exhausted into the room, so as to save cost and reduce complexity and loss rate of the device.
In other embodiments of the present application, the control of the conducting state of the first air intake duct 1 and the second air intake duct 2 may also be achieved simultaneously by a switching module, such as a shunt, which may be changed in state. Fig. 4 is a schematic structural diagram of a fresh air cabinet provided by an embodiment of the present application, and fig. 5 is a schematic structural diagram of a switch module in a fresh air cabinet control device provided by an embodiment of the present application, where fig. 4 and fig. 5 show:
in particular, the switching module 4 may be embodied in the form of a flow divider, which may comprise a manifold 41 and an electromagnetic slide valve 42. In this embodiment, the first air inlet pipe 1 and the second air inlet pipe 2 may share a section of pipe at one end near the air inlet of the fresh air system. An electromagnetic slide valve 42 is provided in the manifold 41 to control the flow path of the air into the fresh air system.
The first end A of the branch pipe 41 is communicated with the air conditioner external fan cavity through the part of the first air inlet pipe 1, which is close to the air conditioner external fan cavity; the second end B is communicated with the outside through a part of the second air inlet pipe 2 close to the outside; the third end C is communicated with an air inlet of the fresh air system through a part, close to the air inlet of the fresh air system, of the first air inlet pipe 1 (namely, a part, close to the air inlet of the fresh air system, of the second air inlet pipe 2). In fig. 4, the space in the dashed frame is used to represent the fan chamber of the air conditioner, the interior of the fan chamber includes the outdoor fan 5 shown in fig. 4, and the heat exchanger 6 is a fresh air cabinet at the outer edge of the dashed frame, and other devices of the fresh air cabinet are not shown in the figure for the sake of brevity.
The electromagnetic slide valve 42 is connected with the control module and is arranged in the branch pipe 41, and is used for sliding downwards and closing the pipe wall of the branch pipe 41 under the control of the control module so as to block the second end F and the third end G while conducting the first end E and the third end G of the branch pipe 41, thereby enabling hot air in a fan cavity of an air conditioner external unit to enter a fresh air system; or the upper slide and the wall of the branch pipe 41 are closed so as to block the first end E and the third end G while the second end F and the third end G of the branch pipe 41 are conducted, thereby enabling the air with the temperature lower than the temperature of the hot air in the fan cavity of the air conditioner external unit in the external environment to enter the fresh air system. Thus, through the arrangement of the branch pipe 41 and the electromagnetic slide valve 42, the material consumption of the pipeline and the number of switches arranged for different pipelines can be greatly reduced, and the cost is saved on the basis of ensuring the functions.
Further, in other embodiments, the length of the branch pipe 41 may be increased, so that different branch pipes of the branch pipe 41 may be directly used as a pipeline between the fan chamber of the air conditioner external unit and the air inlet pipe of the fresh air system, and a pipeline between the outside and the air inlet pipe of the fresh air system, so that the functions of the first air inlet pipeline 1, the second air inlet pipeline 2 and the branch pipe 41 (only used as the branch pipe when the intermediate switching function is performed) are directly realized through the longer branch pipe 41, and the whole pipeline is integrated, so that the subsequent maintenance cost caused by the aging of the fixed component is avoided. And the third end of the branch pipe 41 can be provided with an integrally fixed pipeline to be communicated with the air inlet of the fresh air system, and the first air inlet pipeline 1 and the second air inlet pipeline 2 only comprise the part close to the fan cavity or the outdoor of the air conditioner in the embodiment, so that the reliability of the pipeline is improved.
In practical applications, since the comfortable temperature is generally a zone, in other embodiments of the present application, the conditions for determining whether to introduce the hot air in the fan chamber of the air conditioner into the room in the dehumidification mode may also be determined based on the zone range. For example, after a preset threshold is set, comparing the indoor temperature detected in real time, and when the indoor temperature is lower than the preset threshold and the difference between the indoor temperature and the preset threshold is larger than another fixed value, judging that hot air in a fan cavity of an air conditioner external unit needs to be introduced into a room, so that the first air inlet pipe 1 is conducted and a fresh air system is operated. The essence is to compare the indoor temperature with the same principle as in the above embodiment, so that the description is omitted.
Fig. 6 is a schematic structural diagram of an external unit in a fresh air cabinet provided by the embodiment of the present application at a first view angle, and fig. 7 is a schematic structural diagram of an external unit in a fresh air cabinet provided by the embodiment of the present application at a second view angle, where, as shown in fig. 6 and fig. 7, a baffle 7 may be further disposed in a fan cavity of an external unit of an air conditioner of the fresh air cabinet, for dividing a fan in the fan cavity of the external unit of the air conditioner.
Specifically, the baffle 7 may be disposed between a fan in the fan chamber of the air conditioner external unit and the end of the first air inlet pipe 1 close to the fan chamber of the air conditioner external unit. When temperature regulation and control are needed in a dehumidification mode, the baffle 7 is moved to a first position (the air inlet of the first air inlet pipeline 1 is not blocked), so that hot air in a fan cavity of an external air conditioner enters the first air inlet pipeline 1 and then enters a fresh air system; and in the dehumidification mode, temperature regulation is not needed, and in other modes, the baffle 7 is moved to a second position (for blocking the air inlet of the first air inlet pipeline 1), so that hot air in the fan cavity of the air conditioner external unit cannot enter the first air inlet pipeline 1. Therefore, the hot air leakage in the fan cavity of the air conditioner external unit is avoided, the hot air enters the room when the hot air does not need to enter the room, and the indoor temperature comfort is further ensured.
Further, fig. 8 is a schematic structural diagram of a first air inlet pipe in a fresh air cabinet according to another embodiment of the present application, as shown in fig. 8, a baffle 7 may also be disposed on the first air inlet pipe 1, for example, when the baffle 7 is pulled out, the interior of the first air inlet pipe 1 is turned on, and hot air in a fan cavity of an air conditioner external unit may enter a fresh air system through the first air inlet pipe; when the baffle 7 is inserted, the interior of the first air inlet pipeline 1 is blocked, and hot air in a fan cavity of an air conditioner external unit cannot enter a fresh air system through the first air inlet pipeline; and on the basis of arranging the baffle plate 7, devices such as an air inlet valve 8 and the like can be arranged in the first air inlet pipeline 1, so that the tightness and controllability of the air flow are further ensured.
In addition, the control module mentioned in the above embodiment of the present application may be a separate controller, and in practical application, the control module is added into the fresh air cabinet; the controller can also be an original controller of the fresh air cabinet, and the functions are realized through the input of programs. Moreover, the time for the diverter to conduct the first air inlet pipeline 1 is controlled through the difference value between the indoor temperature and the preset threshold value, and the control of the hot air inlet flow can be realized through controlling the positions of devices such as the air inlet valve 8, so that the hot air entering the fresh air system and the indoor quantity and speed in the fan cavity of the air conditioner outer machine are controlled, the indoor constant temperature state is ensured, and the indoor comfort is greatly improved.
According to the control method of the fresh air cabinet, two inlets of the air inlet end of the fresh air system are designed, and hot air is obtained from the inner side of a fan cavity of an external machine of an air conditioner or ordinary air with relatively low temperature is obtained from the indoor side.
