Description

Technical Field

[0001] This invention relates to the field of air conditioner technology, and more specifically, to a method for rapid temperature adjustment in a localized area of ​​an air conditioner. Background Technology

[0002] The temperature of the air blown by the air conditioner during the cooling process is much lower than the room temperature and the temperature set by the remote control. The current practice is to avoid blowing cold air onto people during the cooling process to prevent discomfort.

[0003] However, by properly controlling the cooling capacity and adjusting the indoor unit's airflow direction, a low-temperature zone can be quickly created in a specific direction within the room. Placing beverages or other items in this zone will quickly cool them down while simultaneously cooling the indoor environment. This is a great benefit for people who want cold drinks in the summer but lack a refrigerator due to budget or space constraints. Similarly, a high-temperature zone can be created in the heating mode during winter.

[0004] Based on this, the applicant proposes a method for rapid temperature adjustment in localized areas of an air-conditioned space to solve the aforementioned technical problems. Summary of the Invention

[0005] The problem solved by this invention is that existing air conditioners have limited functionality and cannot quickly obtain local low-temperature or high-temperature areas.

[0006] To address the aforementioned problems, this invention provides a method for rapid temperature adjustment in a localized area of ​​an air conditioner, comprising the following steps: S1: The user actively selects to put the air conditioner into either a cooling or rapid heating mode. In the cooling or rapid heating mode, the air conditioner directs airflow to a designated area by changing the preset angle of the air guide vane; S2: After the cooling or rapid heating mode is activated, the compressor frequency is increased so that the compressor frequency in the cooling or rapid heating mode is higher than that in the normal mode; S3: The user can place items in the designated area to achieve cooling or rapid heating of the items; S4: After automatically exiting the cooling or rapid heating mode, the compressor frequency returns to normal control; after the user actively exits the cooling or rapid heating mode, the compressor frequency returns to normal control and the air guide vane returns to its initial angle position.

[0007] Compared with existing technologies, the technical effects achieved by this solution are as follows: By setting new functions on the air conditioner, the time required for the air conditioner to heat or cool the indoor temperature to the set temperature can be rationally utilized to achieve the function of cooling or rapid heating mode. Users only need to place items in the set area to achieve cooling or rapid heating of the items. The air conditioner can temporarily act as a refrigerator or heater, thus enabling the air conditioner to serve two purposes. It is relatively simple to implement and is particularly suitable for large factories, rental houses with poor insulation, construction sites, etc.

[0008] In this embodiment, the user actively selects to put the air conditioner into the cooling or quick-heating mode, including: S100: The user sets the indoor temperature through communication control and selects the corresponding cooling or quick-heating mode; S200: The air conditioner enters the cooling or quick-heating mode during the cooling or heating process to the set indoor temperature.

[0009] The technical benefits of this solution are that users can control the indoor temperature, such as to 20°C, via communication, such as an app or remote control, and select the corresponding cooling mode. While the air conditioner cools to 20°C, it can also cool items within the set area. The rapid heating mode works on the same principle as the cooling mode, thus enabling the air conditioner to serve two purposes in one unit.

[0010] In this embodiment, the air conditioner directs airflow to a set area by changing the preset angle of the air guide plate, including: adjusting the angle of the air guide plate by segmenting the air guide plate so that the air outlets on both sides are positioned at the edge of the set area.

[0011] The technical effect of adopting this technical solution is that the air guide plate can be controlled in segments, thereby using a control unit to control multiple air guide plates separately, allowing the air guide plates to adjust their angles, and the air outlets of the air guide plates on both sides to the edge of the set area, so as to determine the set area.

[0012] In this embodiment, the air guide plate is also provided with an indicator device, which includes indicator lights set on the leftmost and rightmost air guide plates, and the indicator lights indicate the location of the set area to the user.

[0013] The technical effect of adopting this solution is that, in order to ensure that users can more intuitively place items into the designated area, indicator lights are installed on the leftmost and rightmost air guide plates. The indicator lights can be powered on when the cooling or fast heating mode is used, so that users can intuitively see the light of the indicator lights and clearly identify the designated area, allowing users to place items into the designated area more quickly.

[0014] In this embodiment, increasing the compressor frequency includes adding a preset operating frequency to the compressor operating frequency in normal mode, including the following formula: factual = f0 + f1, where f0 is the compressor operating frequency in normal mode, f1 is the preset operating frequency, and factual is the actual operating frequency of the compressor in chilling or quick-heating mode.

[0015] The technical effect of adopting this technical solution is that, in order to make simple improvements to existing air conditioners and achieve the above-mentioned cooling and rapid heating functions, a preset operating frequency is added to the compressor operating frequency in normal mode. A higher compressor frequency can achieve the cooling and rapid heating functions.

[0016] In this embodiment, the temperature protection value is lower in the cooling mode than in the normal cooling mode; and higher in the rapid heating mode than in the normal heating mode.

[0017] The technical benefits of this solution are as follows: During cooling, to prevent excessively low indoor temperatures during prolonged operation, the indoor unit coil temperature is limited to around 0 degrees Celsius in normal mode (protection is activated if it falls below 0 degrees Celsius). In ice-cooling mode, the protection level can be raised to -5 degrees Celsius or even lower. The same principle applies to rapid heating mode. This allows for achieving lower or higher temperature ranges within the set temperature range.

[0018] In this embodiment, when the indoor temperature is heated or cooled to the user's desired temperature, the compressor frequency returns to normal control, and the air guide plate angle remains unchanged; when the user exits the cooling or quick-heating mode, the compressor frequency returns to normal control, and the air guide plate returns to its initial state.

[0019] The technical effect of adopting this solution is that when the air conditioner adjusts the indoor temperature to the user's desired temperature, the corresponding compressor frequency returns to the normal mode frequency, and the air guide plate angle can remain in the state of the cooling or quick heating mode. It can also obtain a lower or higher temperature in the set area. When the user exits the cooling or quick heating mode, the compressor frequency returns to normal, the air guide plate returns to its initial state, and the air conditioner realizes its original cooling and heating mode.

[0020] In this embodiment, when the air guide plate changes its preset angle, the corresponding set area changes.

[0021] The technical effect of adopting this technical solution is that when the preset angle of the air guide plate changes, the edge of the corresponding preset area will also change, that is, the size of the corresponding preset area will also change. When the size of the preset area is smaller, the cooling or heating effect is better because the air volume is more concentrated.

[0022] In this embodiment, the higher the air speed of the air conditioner, the closer the temperature of the set area is to the indoor unit coil temperature.

[0023] The technical effect of adopting this solution is that, in order to make the temperature of the set area closer to the temperature of the indoor unit coil, so as to make the heating or cooling efficiency better, the higher the air conditioner's fan speed, the better the heating or cooling effect of the set area.

[0024] In this embodiment, an air conditioner employs the aforementioned method for rapid temperature adjustment in a localized area. Attached Figure Description

[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] This invention provides a method for rapid temperature adjustment in a local area of ​​an air conditioner, comprising the following steps: S1: The user actively selects to put the air conditioner into a cooling or fast-heating mode. In the cooling or fast-heating mode, the air conditioner directs airflow to a set area by changing the preset angle of the air guide plate; S2: After the cooling or fast-heating mode is activated, the compressor frequency is increased so that the compressor frequency in the cooling or fast-heating mode is higher than that in the normal mode; S3: The user can place items in the set area to achieve cooling or fast heating of the items; S4: After automatically exiting the cooling or fast-heating mode, the compressor frequency returns to normal control; after the user actively exits the cooling or fast-heating mode, the compressor frequency returns to normal control and the air guide plate returns to its initial angle position.

[0030] The air conditioner in this embodiment can be a wall-mounted air conditioner, a floor-standing air conditioner, or an air conditioner installed in a large factory, a rental house with poor insulation, a construction site, or similar location.

[0031] Users can remotely control the room to set the desired temperature using a remote control or an app, and can switch between cooling and rapid heating modes accordingly. In cooling mode, the airflow is directed to the set area by adjusting the preset angle of the air guide vane. The adjustment method can employ segmented control of the air guide vane, as described in patent publication CN112797591B's method, device, and air conditioner for switching segmented airflow modes, where the angle of the segmented air guide vane is adjusted separately. Initially, the set area is set to 1 / 4 of the width of the air outlet area, such as... Figure 1 As shown.

[0032] When adjusting the angle of the air guide plate, such as Figure 2 As shown, to make the coverage area of ​​the set area smaller, the wind speed will be higher, and the cooling effect will be greater; as Figure 3 As shown, to maximize the coverage area of ​​the set zone, a lower wind speed results in a slightly weaker cooling effect. Users can adjust the angle of the air guide plate according to the quantity of items and their needs.

[0033] When using the quick-heat mode, the principle is the same as the chilled mode.

[0034] Since this application adds a rapid heating mode and a chilling mode on the basis of the existing technology, the original compressor operating frequency cannot meet the above requirements. Therefore, in the rapid heating mode and the chilling mode, the compressor operating frequency is higher than the compressor frequency in the normal mode.

[0035] When the indoor temperature reaches the user's desired temperature, the user can manually exit the cooling or quick-heating mode (via remote control or app). At this point, the compressor frequency returns to normal, and the angle of the air deflector also returns to normal. Alternatively, the user can maintain the current mode, achieving either a higher (heating mode) or lower (heating mode) temperature within the set area. This ensures that items within the set area remain warm.

[0036] Further optimization allows users to actively choose to put the air conditioner into either cooling or quick-heating mode, including: S100: The user sets the indoor temperature and selects the corresponding cooling or quick-heating mode via communication control; S200: The air conditioner enters cooling or quick-heating mode during the cooling or heating process to the set indoor temperature.

[0037] The communication control method is a relatively common control method in existing technology. It only requires adding a new chill / quick heat button function to the remote control or adding a chill / quick heat button to the APP control program. Since the existing technology does not make timely use of the cold or hot air generated during the heating or cooling process to the set temperature, this application can make reasonable use of the cold or hot air generated during this period to heat or chill the set area, so that the air conditioner can temporarily act as a heater or refrigerator.

[0038] Further optimization involves the air conditioner directing airflow to a designated area by changing the preset angle of the air guide vane. This includes adjusting the angle of the air guide vane using a segmented control method, so that the air outlets on both sides of the air guide vane are positioned at the edge of the designated area.

[0039] The designated area is determined by the left end of the leftmost air guide plate and the right end of the rightmost air guide plate. The angle of the air guide plates changes, resulting in a change in the angle of the blown air. This designation area is suitable for placing items on a table or the ground. The preset angle can be set in advance to multiple levels; the preset angle is... Figure 1 , 2 The angles 1, 2, and 3 in the options, such as 15°, 30°, 45°, 60°, and 75°, can be selected by the user to achieve different sized settings for the area.

[0040] Further optimization includes the addition of an indicator device on the air guide plate. This device includes indicator lights located on the leftmost and rightmost air guide plates, which indicate the location of the set area to the user.

[0041] To ensure users can more intuitively place items within the designated area, indicator lights are installed on the leftmost and rightmost air guide plates. These lights are powered on in either cooling or rapid heating mode, allowing users to clearly see the light and pinpoint the designated area, enabling them to place items more quickly. The indicator lights can be LEDs, similar to spotlights, to guide users in placing items within the designated area.

[0042] Further optimizations include increasing the compressor frequency by adding a preset operating frequency to the compressor operating frequency in normal mode, using the following formula: factual = f0 + f1, where f0 is the compressor operating frequency in normal mode, f1 is the preset operating frequency, and factual is the actual operating frequency of the compressor in chilling or quick-heating mode.

[0043] Wherein, when factual > fmax, then factual = fmax, to ensure that the actual operating frequency does not exceed the maximum frequency. fmax is the maximum operating frequency of the compressor, and f1 is the preset operating frequency, which is the set value. A series of data can be obtained through experimental testing. When the difference between the actual indoor temperature and the set temperature is different, different f1 values ​​are taken to ensure the smoothness of frequency control and avoid excessive changes in room temperature that may cause discomfort to the human body. The initial compressor wind speed is the maximum wind speed.

[0044] Further optimizations have been made: in the cooling mode, the temperature protection value is lower than in the normal cooling mode; in the rapid heating mode, the temperature protection value is higher than in the normal heating mode.

[0045] During cooling, to prevent the indoor temperature from dropping too low during prolonged operation, the indoor unit's coil temperature is normally limited to around 0 degrees Celsius (it will activate protection if it falls below 0 degrees). In the cooling function, this protection level can be raised to -5 degrees Celsius or even lower. Similarly, in heating mode, the corresponding protection can be released, allowing the indoor unit's coil temperature to rise further. Combined with high fan speed, this creates a lower / higher temperature range within the set area.

[0046] Further optimizations include: when the indoor temperature is heated or cooled to the user's desired temperature, the compressor frequency returns to normal control, and the air guide plate angle remains unchanged; when the user exits the cooling or quick-heating mode, the compressor frequency returns to normal control, and the air guide plate returns to its initial state.

[0047] The air conditioner remains in this mode until the indoor temperature reaches the set temperature or the user exits this function, continuously and rapidly cooling or heating items within the designated area. Once the indoor temperature reaches the set temperature, the compressor frequency returns to normal control to prevent uncontrolled room temperature regulation, but the air deflector maintains this set angle until the user exits this function or the unit is turned off.

[0048] Further optimization: when the air guide plate changes its preset angle, the corresponding set area changes.

[0049] When adjusting the angle of the air guide plate, such as Figure 2 As shown, to make the coverage area of ​​the set area smaller, the wind speed will be higher, and the cooling effect will be greater; as Figure 3 As shown, to maximize the coverage area of ​​the set zone, a lower wind speed results in a slightly weaker cooling effect. Users can adjust the angle of the air guide plate according to the quantity of items and their needs.

[0050] Further optimization shows that the higher the air conditioner's fan speed, the closer the temperature of the corresponding set area will be to the indoor unit's coil temperature.

[0051] At the same distance, the faster the wind speed, the shorter the time it takes for the cool / hot air to exchange heat with the indoor environment, and the closer it gets to the coil temperature.

[0052] The present invention also provides an air conditioner that employs a method for rapid temperature adjustment in a localized area.

[0053] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
