Description

Technical Field

[0001] This invention relates to the field of refrigeration equipment technology, and in particular to a refrigerator-air conditioner integrated unit, a refrigeration control system, and a refrigeration control method. Background Technology

[0002] Portable air conditioners, as a type of air conditioning product that combines portability and practicality, are becoming increasingly popular in various situations where it is inconvenient to use conventional air conditioning, such as short-term rental rooms, corridor shops, and temporary duty posts. In these situations, users often cannot equip themselves with a refrigerator to meet their needs for refrigerating food or drinks.

[0003] To address the aforementioned issues, existing technologies add a refrigeration component to a portable air conditioner to create a device that integrates both air conditioning and refrigeration. While this solves the problem of simultaneously meeting the needs of both air conditioning and refrigeration, the existing integrated refrigerator-air conditioner requires further refinement in its system operation to ensure the stable functioning of both air supply and refrigeration functions.

After the refrigerant dissipates heat through the condenser, it is regulated by the throttling capillary tube and then flows sequentially to the refrigeration components and the evaporator for refrigeration treatment, and then is returned to the refrigerant storage device. Alternatively, the compressor is controlled to output the refrigerant to the condenser. After the refrigerant dissipates heat through the condenser, it is regulated by the throttling capillary tube and then flows sequentially to the evaporator and the refrigeration components for refrigeration treatment, and then is returned to the refrigerant storage device.

[0012] Thirdly, embodiments of the present invention provide a refrigeration control method, applied to a single refrigeration loop in a refrigeration control system as described above, comprising:

[0013] When the refrigerator-air conditioner unit is started, the compressor is controlled to start and the refrigerant in the refrigerant storage device is delivered to the condenser.

[0014] When the refrigerator-air conditioner unit is started, the compressor is controlled to start and the refrigerant in the refrigerant storage device is delivered to the condenser.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0039] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0040] like Figure 1 and Figure 2 As shown in the figure, an embodiment of the present invention provides a refrigerator-air conditioner combo unit, including: a housing 900 and a refrigerant storage device 50 disposed within the housing 900 (not shown in the figure, see reference). Figure 5 (Control logic diagram), compressor 300, condenser 400, refrigeration components and evaporator 800;

[0041] The refrigerant storage device 50 is connected to the compressor 300, and the compressor 300 is connected to the condenser 400;

[0042] The condenser 400 is connected to the refrigeration component and the evaporator 800 simultaneously, and the refrigeration component and the evaporator 800 are connected to the refrigerant storage device 50 simultaneously, forming a dual refrigeration circuit; or the condenser 400, the refrigeration component, the evaporator 800 and the refrigerant storage device 50 are connected in sequence, forming a single refrigeration circuit; or the condenser 400, the evaporator 800, the refrigeration component and the refrigerant storage device 50 are connected in sequence, forming a single refrigeration circuit.

[0043] The refrigerator-air conditioner unit in this embodiment combines refrigeration and air supply functions, and is designed with multiple operating modes.

[0044] In some operating modes, such as Figure 5As shown, a dual refrigeration circuit is designed. Circuit 1 can be a loop consisting of refrigerant storage device 50, compressor 300, condenser 400, refrigeration component, and refrigerant storage device 50 connected in sequence. Circuit 2 can be a loop consisting of refrigerant storage device 50, compressor 300, condenser 400, evaporator 800, and refrigerant storage device 50 connected in sequence. Circuits 1 and 2 are connected in parallel to form a dual refrigeration circuit. Specifically, the parallel connection method is as follows: condenser 400 is simultaneously connected to refrigeration component and evaporator 800 via first circuit solenoid valve 10 and second circuit solenoid valve 20, respectively; refrigeration component is connected to refrigerant storage device 50 via first circuit check valve 30; and evaporator 800 is connected to refrigerant storage device 50 via second circuit check valve 40. This constitutes a dual refrigeration circuit, and based on this dual refrigeration circuit, separate operation modes for refrigeration function, separate operation mode for air supply function, and simultaneous operation mode are realized.

[0045] In some operating modes, such as Figure 6 As shown, a single refrigeration loop is designed, specifically as follows: refrigerant storage device 50 - compressor 300 - condenser 400 - refrigeration components - evaporator 800 - refrigerant storage device 50 are connected in series to form a loop. Alternatively, the refrigerant storage device 50 - compressor 300 - condenser 400 - evaporator 800 - refrigeration components - refrigerant storage device 50 are connected in series to form a loop. Based on this single refrigeration loop, a simultaneous operation mode of refrigeration and air supply functions is achieved. Preferably, the condenser 400 and the refrigeration components are connected via a throttling capillary tube 60, or the condenser 400 and the evaporator 800 are connected via a throttling capillary tube 60.

[0046] Based on the dual or single refrigeration circuit designed in this embodiment, the stable operation of the air supply and refrigeration functions of the refrigerator-air conditioner integrated unit is achieved.

[0047] like Figure 2 As shown, in one embodiment, the refrigerator-air conditioner unit may further include: a first air duct component 600, with a first air inlet and a first air outlet provided on the side of the outer casing 900; the compressor 300, the condenser 400 and the first air duct component 600 are located sequentially between the first air inlet and the first air outlet, forming a first airflow channel.

[0048] In this embodiment, the first airflow channel (reference) Figure 2 The path A1 in the code is used to dissipate heat generated inside the refrigerator-air conditioner unit.

[0049] Specifically, air is introduced into the interior of the refrigerator-air conditioner unit through the first air inlet. Inside the unit, the air passes through the compressor 300 and condenser 400 in sequence and is cooled. Then, it is drawn into the first air duct component 600 and discharged through the first exhaust port, thereby achieving the circulation function.

[0050] like Figure 2 As shown, in one embodiment, the refrigerator-air conditioner unit further includes: a second air duct component 700, a second air inlet and a second air outlet are provided on the side of the outer casing 900, and the evaporator 800 and the second air duct component 700 are located between the second air inlet and the second air outlet in sequence to form a second airflow channel.

[0051] In this embodiment, the second airflow channel (reference) Figure 2 The path A2) is used to implement the cooling and air supply function of the refrigerator-air conditioner integrated unit.

[0052] Specifically, air is introduced into the interior of the refrigerator-air conditioner unit through the second air inlet. The air is first cooled by the evaporator 800, then drawn in by the second air duct component 700, and finally discharged through the second air outlet, thereby achieving the cooling and air supply function.

[0053] In one embodiment, the first airflow channel is located below the refrigerator-air conditioner unit, the second airflow channel is located above the refrigerator-air conditioner unit, and a refrigeration cabinet 100 is also provided above the refrigerator-air conditioner unit, with refrigeration components disposed on the side of the refrigeration cabinet 100.

[0054] In this embodiment, the first airflow channel and the second airflow channel are divided into regions that do not interfere with each other, thus not affecting the cooling and air supply effect or the heat dissipation effect. The refrigeration unit 100 is positioned above the refrigerator-air conditioner combo unit to achieve the refrigeration function.

[0055] The refrigerator-air conditioner unit in this embodiment also includes a chassis 500 and a water tray 200. The outer shell 900 covers the chassis 500, and the water tray 200 is located above the chassis 500. The interior of the refrigerator-air conditioner unit can be divided into upper and lower sections with the water tray 200 as the boundary. That is, the first airflow channel is located below the water tray 200, and the second airflow channel is located above the water tray 200.

[0056] Understandably, the heat generated inside the machine is mainly produced by the compressor 300 and the condenser 400. The compressor 300, condenser 400, and first air duct component 600 can be positioned within the space between the chassis 500 and the water tray 200. The compressor 300 and condenser 400 can be mounted on the chassis 500, and the first air duct component 600 can be mounted on the inner wall of the outer casing 900. The compressor 300, condenser 400, and first air duct component 600 can be arranged side-by-side in sequence. The first air inlet can be located on the side wall of the outer casing 900 near the compressor 300, and the first air outlet can be located on the rear wall of the outer casing 900, thus forming a... Figure 2 The path A1 is shown.

[0057] It should be understood that the positions of the compressor 300, condenser 400, and first air duct component 600 are not limited to... Figure 2 The distribution shown can be adapted to the actual situation; that is, path A1 can also be adapted to the distribution of the components under the refrigerator-air conditioner unit.

[0058] Understandably, placing the second airflow channel above the refrigerator-air conditioner unit can achieve better air delivery; that is, the evaporator 800 and the second air duct component 700 are located above the water tray 200. Correspondingly, the second air inlet can be placed on the side of the outer casing 900 near the evaporator 800, and the second exhaust outlet can be placed on the side of the outer casing 900 for easier exhaust. Preferably, in this embodiment, the evaporator 800 is placed inside the rear side of the outer casing 900, the second air inlet is placed on the rear side of the outer casing 900, and the second exhaust outlet is placed on the top of the outer casing 900; thus forming... Figure 2 The path A2 is shown.

[0059] Understandably, placing the refrigeration unit 100 above the refrigerator-air conditioner unit allows for better operation. The refrigeration unit 100 can be arranged side by side with the evaporator 800 and the second air duct component 700, preferably arranged from front to back in sequence. This saves more space and allows for both air conditioning and refrigeration functions to be achieved with less space.

[0060] In some embodiments, the water tray 200 can be a hexahedral structure. The water tray 200 is horizontally disposed inside the outer casing 900 and can be connected to the inner wall of the outer casing 900 through its side. The size of the water tray 200 can be adaptively adjusted according to the size of different portable air conditioners.

[0061] In some embodiments, such as Figure 4As shown, a door 106 is provided on the top and / or side of the main body 101. The inner side of the door 106 can be flush with the inner side of the refrigeration box 100, and the outer side of the door 106 can be flush with the outer shell 900. Insulation strips can be attached to the edge of the door 106. The door 106 can be opened upward or forward.

[0062] In some embodiments, an adjustable air guide plate 901 is provided on the second exhaust vent to adjust the air supply angle.

[0063] In some embodiments, a first air inlet grille is provided on the side of the housing 900 near the compressor 300, and the grille openings on the first air inlet grille form a first air inlet. A second air inlet grille is provided on the side of the housing 900 near the evaporator 800. The grille openings on the second air inlet grille form a second air inlet. It should be understood that the opening shapes, arrangements, etc., of the first and second air inlet grilles on the housing 900 for introducing air can be configured according to airflow principles.

[0064] In some embodiments, the outer casing 900 is also provided with a duct that communicates with the outside, and the duct is connected to the first exhaust vent to facilitate the exhaust of hot air to the outside.

[0065] In some embodiments, multiple casters 501 may be provided at the bottom of the chassis 500 to facilitate the movement of the refrigerator-air conditioner unit.

[0066] like Figure 3 As shown, in one embodiment, the refrigeration box 100 may include a main box 101 with a main opening on one side and a secondary box 105 with a secondary opening on one side. The main box 101 and the secondary box 105 are connected to each other through the main opening and the secondary opening. The refrigeration component is installed in the secondary box 105. The refrigeration component may be a refrigeration coil 103. A coil support 104 is installed on the secondary box 105, and the refrigeration coil 103 is installed on the coil support 104. A protective net 102 is installed between the main opening and the secondary opening.

[0067] In this embodiment, the main housing 101 and the auxiliary housing 105 are connected and communicate with each other through the main opening and the auxiliary opening. The right side and top surface of the coil support 104 are respectively connected and fixed to the corresponding inner wall of the auxiliary opening. The bottom and one side of the bottom of the auxiliary opening have openings for the refrigeration coil 103 to enter and exit. After the refrigeration coil 103 enters the auxiliary housing 105 through the opening, it is fixed by a circular groove provided on the left side of the coil support 104. A protective net 102 is installed between the main opening and the auxiliary opening to separate the main housing 101 and the auxiliary housing 105.

[0068] It should be understood that the diameter and length of the refrigeration coil 103 and its placement scheme are not limited to those shown in the figure. They can be adjusted according to the actual situation. The groove distribution of the coil support 104 can be adjusted to match the refrigeration coil 103.

[0069] It should be understood that the protective netting 102 may be made of metal or plastic mesh.

[0070] It should be understood that the shells of the main enclosure 101 and the auxiliary enclosure 105 can be made of metal or plastic, and the shell sandwich layer is filled with thermal insulation material, the thickness of which is controlled between 5-10mm.

[0071] It should be understood that the cooling method in the refrigeration box 100 is not limited to coil radiation cooling; a fan and fins can be used to form an air-cooled refrigeration box 100.

[0072] The air duct structure is described in detail below:

[0073] In one embodiment, both the first air duct component 600 and the second air duct component 700 include a fan, a fan blade, and an air duct pipe. The fan is installed inside the air duct pipe, and the fan blade is located inside the air duct pipe and connected to the fan shaft.

[0074] In some implementations, such as Figure 2 As shown, the first air duct component 600 may include a lower fan 602, a lower fan blade 601, and a lower air duct pipe 603. The lower fan 602 is installed inside the lower air duct pipe 603, and the lower fan blade 601 is located inside the lower air duct pipe 603 and connected to the shaft of the lower fan 602. The opening of the lower air duct pipe 603 protrudes outside the outer casing 900. Air is introduced into the machine body through the first air inlet, passes through the compressor 300, and then undergoes heat exchange through the condenser 400 before being drawn into the lower air duct pipe 603. At this time, the lower fan 602 drives the lower fan blade 601 to rotate, thereby discharging the hot air along the direction of the lower air duct pipe 603 to the first exhaust port on the outer casing 900, and then exhausting it to the outside through the air duct, thus achieving the heat dissipation function.

[0075] In some implementations, such as Figure 2 As shown, the second air duct component 700 may include: an upper fan 702, an upper fan blade 701, and an upper air duct 703. The upper fan 702 is installed inside the upper air duct 703, and the upper fan blade 701 is located inside the upper air duct 703 and connected to the shaft of the upper fan 702. The opening of the upper air duct 703 faces the second air outlet at the top of the housing 900. Air is introduced into the evaporator 800 through the second air inlet and cooled to form cold air, which then enters the upper air duct 703. At this time, the upper fan 702 drives the upper fan blade 701 to rotate, which blows the cooled air upward along the direction of the upper air duct 703 to the second air outlet, and then blows it out through the air guide plate 901, thereby realizing the cooling air supply function.

[0076] This invention provides a refrigeration control method, such as... Figure 7 As shown, the method applied to the dual refrigeration circuit of a refrigerator-air conditioner combo unit may include steps S701 to S703:

[0077] S701, Get the current operating mode;

[0078] S702. When the operating mode is dual cooling mode, the compressor 300 is started and the refrigerant in the refrigerant storage device 50 is output to the condenser 400. After the refrigerant is cooled by the condenser 400, it is regulated by the first circuit solenoid valve 10 and the second circuit solenoid valve 20. After being regulated by the first circuit solenoid valve 10, it flows to the refrigeration component for refrigeration and is then returned to the refrigerant storage device 50. After being regulated by the second circuit solenoid valve 20, it flows to the evaporator 800 for refrigeration and is then returned to the refrigerant storage device 50.

[0079] S703. When the operating mode is single refrigeration mode, the compressor 300 is started and the refrigerant in the refrigerant storage device 50 is output to the condenser 400. After the refrigerant is cooled by the condenser 400, it is regulated by the throttling capillary tube 60 and then flows sequentially to the refrigeration components and the evaporator 800 for refrigeration treatment before being returned to the refrigerant storage device 50. Alternatively, the compressor 300 is controlled to output the refrigerant to the condenser. After the refrigerant is cooled by the condenser 400, it is regulated by the throttling capillary tube 60 and then flows sequentially to the evaporator 800 and the refrigeration components for refrigeration treatment before being returned to the refrigerant storage device 50.

[0080] In this embodiment, when the user selects the dual cooling mode, both loop one and loop two of the dual cooling circuit are activated simultaneously to enable the dual circuits to operate at the same time, and the air supply function and the refrigeration function are realized based on the control steps of step S702.

[0081] When the user selects the refrigeration-only mode in the single refrigeration mode, only the first circuit of the dual refrigeration circuit is activated, and the refrigeration function is implemented based on step S703.

[0082] When the user selects the air conditioning mode in the single cooling mode, only the second circuit of the dual cooling circuit is turned on, and the air supply function is implemented based on step S703.

[0083] This embodiment, based on the control method of steps S701 to S703, provides a separate operation mode for the refrigeration function, a separate operation mode for the air supply function, and a simultaneous operation mode under dual refrigeration circuits.

[0084] In one embodiment, when the operating mode is dual cooling mode, the method further includes:

[0085] The refrigeration temperature of the refrigeration component is periodically monitored. When the refrigeration temperature is lower than the preset temperature, the supply of some refrigerant to the refrigeration component is stopped for refrigeration. When the refrigeration temperature is higher than the preset temperature, the supply of some refrigerant to the refrigeration component continues for refrigeration.

[0086] In this embodiment, the refrigeration temperature of the refrigeration component (i.e., the temperature inside the refrigerator compartment) is detected every first preset time interval (preferably 10 minutes). When the temperature is lower than the preset temperature (preferably 10°C), the refrigeration circuit to the refrigeration component is closed; when the temperature is higher than the preset temperature, the refrigeration circuit to the refrigeration component is opened. In dual-refrigeration mode, the compressor 300 operates normally. When the refrigeration circuit to the refrigerator compartment is opened, the compressor 300 will increase its frequency (Hz), and the speed of the lower fan 602 will correspondingly increase (rpm). When the refrigeration circuit to the refrigerator compartment is closed, the compressor 300 and the lower fan 602 will return to normal operation.

[0087] Understandably, in this embodiment, after detecting that the door 106 has been opened, the refrigeration temperature inside the refrigeration chamber 100 can be lowered to achieve a rapid refrigeration effect, and then adjusted back to the normal refrigeration temperature after a certain period of time (preferably 10 min-30 min).

[0088] Understandably, this embodiment can also be equipped with weight or vision sensors to determine whether there are items inside the refrigeration box 100 in order to determine whether to open the refrigeration circuit leading to the refrigeration component.

[0089] In one embodiment, such as Figure 8 As shown, step S701 may include:

[0090] S801, Detect the user's selection command;

[0091] S802. If a user command is detected within the set time period, the current operating mode is confirmed according to the user command; if no user command is detected within the set time period, the default mode is used as the current operating mode.

[0092] Alternatively, check if there are any items to be cooled. If so, confirm that the current operating mode is either dual cooling mode or operating mode containing only the cooling component.

[0093] In some implementations of this embodiment, within a set time (preferably 10 seconds) after the refrigerator-air conditioner unit is turned on, based on the instruction selected by the user using the remote control or mobile panel, if the user's instruction is received, the current operating mode is confirmed according to the instruction; if no instruction is received within the set time, the default mode is used as the current operating mode.

[0094] In some other implementations of this embodiment, a weight sensor or a vision sensor can be installed on the refrigeration box 100 to determine whether there are items inside the refrigeration box 100. If there are, it can be confirmed that the current operating mode is a dual refrigeration mode or a refrigeration-only mode.

[0095] This invention also provides a refrigeration control method applied to a single refrigeration circuit in a refrigerator-air conditioner integrated unit. The method may include:

[0096] When the refrigerator-air conditioner unit is started, the compressor 300 is activated and the refrigerant in the refrigerant storage device 50 is output. The refrigerant passes through the condenser 400 and then reaches the refrigeration components and evaporator 800 for refrigeration treatment before being returned to the refrigerant storage device 50; or
