[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0030] Reference Figures 1 to 5 As shown, a precision air conditioner indoor unit provided according to an embodiment of the present utility model includes a housing 100, an indoor unit heat exchange system 200, and an electrical control box 300. Specifically, the housing 100 includes a left side plate, a right side plate, a top plate, a bottom plate, and a back plate. The left side plate, right side plate, top plate, and bottom plate surround and form the outer peripheral wall of the housing 100. The left side plate, right side plate, top plate, and bottom plate are respectively connected to the back plate to form a housing 100 with a front opening.

[0031] The enclosure 100 has an openable and closable first chamber 120 and an openable and closable second chamber 130 inside. The first chamber 120 and the second chamber 130 are arranged sequentially along the length of the enclosure 100. The enclosure 100 is provided with an air inlet 140 and an air outlet 150 that communicate with the first chamber 120 respectively. The back panels of the first chamber 120 and the second chamber 130 are integrally formed to form the back panel 180 of the enclosure. The enclosure 100 is also provided with mounting parts 190 on both sides for mounting the enclosure 100.

[0032] The indoor unit heat exchange system 200 includes an evaporator 210, a fan 220, and a compressor 230. The evaporator 210 and the fan 220 are respectively installed in the first chamber 120. The evaporator 210 is bolted to a fixing plate 123 in the first chamber 120. A wet film fixing component 211 is connected to one side of the evaporator 210, and a wet film humidifier is installed inside the wet film fixing component 211. The evaporator 210 is located between the air inlet 140 and the air outlet 150. The air inlet end of the fan 220 faces the evaporator 210, and the air outlet end of the fan 220 faces the air outlet 150. The compressor 230 is installed on a support 131 in the second chamber 130, and the compressor 230 is connected to the evaporator 210 and the condenser pipes in the outdoor unit through a valve assembly 240. The evaporator 210 is also connected to the condenser pipes in the outdoor unit through the valve assembly 240, thereby forming a circulating refrigeration system.

[0033] Specifically, the valve assembly 240 includes a first shut-off valve 242 (needle valve), a dryer filter 243, a solenoid valve 244, a sight glass 245, an expansion valve 246, a distributor 241, and a second shut-off valve 247 (needle valve). The first shut-off valve 242, dryer filter 243, solenoid valve 244, sight glass 245, and expansion valve 246 are disposed in the second chamber 130 and connected sequentially along the refrigerant flow direction. The expansion valve 246 is connected by a copper tube passing through the partition 110. The pipe is connected to the distributor 241, which is connected to the evaporator 210 to evenly input the refrigerant into each pipe in the evaporator 210. The distributor 241 is connected to the second shut-off valve 247 through another copper pipe passing through the partition 110. The first shut-off valve 242 and the second shut-off valve 247 are respectively located on the inner wall of the second chamber 130 on the side away from the first chamber 120. The first shut-off valve 242 and the second shut-off valve 247 are respectively connected to the inlet and outlet of the condenser in the outdoor unit.

[0034] It should be added that the first chamber 120 is also equipped with a first sensor group for inlet and outlet air temperature and humidity, and the second chamber 130 is also equipped with a second sensor group for detecting the suction temperature, exhaust temperature and suction pressure of the compressor 230. The compressor 230 is also equipped with a low-pressure switch and a high-pressure switch on both sides. Since the temperature control and humidity control of precision air conditioners are mature technologies, there are also mature products available for the sensors, which will not be described in detail here.

[0035] The electrical control box 300 is installed in the second chamber 130 and is located in front of the compressor 230 along the width direction of the housing 100 (in this embodiment, the length direction of the housing 100 is defined as the left-right direction and the width direction of the housing 100 is defined as the front-back direction, which is specifically mentioned here and will not be repeated hereafter). The electrical control box 300 is electrically connected to the first sensor group, the second sensor group, the evaporator 210, the compressor 230 and the fan 220 respectively.

[0036] When the precision air conditioner starts, the fan 220 in the housing 100 is run first. After the fan 220 runs for a certain period of time, the expansion valve 246 is opened to balance the pressure. Then, the compressor 230 and the solenoid valve 244 are started simultaneously. At this time, the expansion valve 246 automatically adjusts its opening according to the superheat to precisely control the refrigerant flow. After the compressor 230 starts, high and low pressures are formed, and the speed of the outdoor unit is automatically adjusted according to the high pressure. After the compressor 230 starts, the refrigerant is compressed into a high-temperature and high-pressure gas in the compressor 230. It passes through the second shut-off valve 247 and reaches the outdoor unit condenser, where it is cooled into a high-pressure and medium-temperature liquid. It then returns to the indoor unit, passing through the first shut-off valve 242, the dryer filter 243, the solenoid valve 244, and the sight glass 245, before reaching the expansion valve 246 for throttling and expansion. It then enters the evaporator 210 through the distributor 241 to evaporate and absorb heat, becoming a low-pressure and low-temperature gas that returns to the compressor 230.

[0037] Understandably, by setting up a first chamber 120 and a second chamber 130, arranged sequentially along the length of the housing 100, the original vertical layout of the precision air conditioner indoor unit is changed to a horizontal layout, making the indoor unit flatter. Furthermore, the compressor 230 and the electrical control box 300 are integrated into the second chamber 130, improving the space utilization within the housing 100 and effectively reducing the size of the indoor unit to suit installation environments with limited space. Simultaneously, due to the reduced size of the indoor unit, the wall-mounted area of ​​the housing 100 is also reduced, allowing users to install the indoor unit either floor-mounted or wall-mounted, increasing installation flexibility.

[0038] Furthermore, a heating belt is wound around the outer peripheral wall of the compressor 230. Optionally, a single heating belt may be provided, or multiple heating belts may be provided at intervals along the vertical direction.

[0039] After the refrigerant absorbs heat through evaporation in the evaporator 210, it is absorbed by the compressor 230. Because the refrigerant is in a low-pressure, low-temperature gaseous state at this time, its fluidity is low, which may cause compressor 230 malfunction. By installing a heating belt, the compressor 230 can be heated, maintaining the refrigerant oil in the compressor 230 at a suitable flow temperature, thus preventing compressor 230 malfunction and ensuring its operating efficiency.

[0040] Reference Figure 1 and Figure 2As shown, it can be understood that a partition 110 is provided between the first chamber 120 and the second chamber 130. The housing 100 also includes a housing body (i.e., a housing structure with a front opening formed by the left side panel, right side panel, top panel, bottom panel, and back panel) and a first panel 160 detachably connected to the housing body. Optionally, the first panel 160 can be detachably connected to the housing 100 by means of screws, snaps, pins, etc. The first chamber 120 is formed between the first panel 160, the inner wall of the housing body, and the partition 110. An air inlet 140 is opened on the first panel 160, and an air outlet 150 is opened on the first panel 160 or the top panel.

[0041] The location of the air outlet 150 can be determined according to the actual needs of the computer room or the installation location of the enclosure 100. For example, the air inlet 140 can be opened on the first panel 160 and located above the air outlet 150. In this case, the upper end of the evaporator 210 is tilted forward and located between the air outlet 150 and the air inlet 140, thereby separating the air inlet 140 and the air outlet 150 within the first chamber 120. The fan 220 is set as a centrifugal fan 220, and the fan 220 is located above the evaporator 210. The airflow direction on the enclosure 100 is bottom inlet and top outlet. The air inlet 140 can also be opened... Located on the top wall of the box, the upper end of the evaporator 210 is tilted forward, and the fan 220 is set as an axial flow fan 220, located above the evaporator 210. The airflow direction on the box 100 is bottom inlet and top outlet. The air inlet 140 can also be opened on the first panel 160 and located below the air outlet 150. In this case, the lower end of the evaporator 210 is tilted forward and located between the air outlet 150 and the air inlet 140. The fan 220 is set as a centrifugal fan 220, located below the evaporator 210. The airflow direction on the box 100 is top inlet and bottom outlet.

[0042] Due to the flat design of the enclosure 100, its installation position is also quite flexible. Based on this, the air outlet 150 can be strategically positioned to allow air to be discharged from different locations within the enclosure 100, thus adapting to different computer room environments and improving the practicality of the precision air conditioning indoor unit.

[0043] It should be added that a filter 121 is also provided on the side of the first panel 160 facing the evaporator 210. The filter 121 can filter dust and impurities at the air inlet 140, so as to avoid damaging the evaporator 210 and ensure clean airflow.

[0044] Reference Figure 2 and Figure 3 As shown, it can be understood that the air outlet 150 is opened on the first panel 160 and located above the air inlet 140. The air outlet 150 is provided with an air guide grille 151, the front end of which is inclined upward. Meanwhile, the air inlet 140 on the first panel 160 is arranged in a honeycomb pattern to increase the air inlet area of ​​the first panel 160.

[0045] The front end of the air guide grille 151 is tilted upwards, and the airflow blown out by the fan 220 is tilted upwards under the guidance of the air guide grille 151, so that there is a certain angle between the hot air a drawn in by the first panel 160 and the cold air b blown out, so as to avoid the cold air b that has just been blown out being immediately drawn back into the first chamber 120 from the air inlet 140, which would affect the heat exchange efficiency.

[0046] It should be added that a downward-facing grille can also be installed at the air inlet 140, while the grille at the air outlet 150 can be installed horizontally to avoid the hot air a being drawn in at the first panel 160 and the cold air b being blown out being parallel, thereby improving the heat exchange efficiency.

[0047] Reference Figure 2 As shown, it can be understood that a support plate 122 is provided in the first chamber 120, and a fan 220 is connected to a mounting bracket 221. The mounting bracket 221 and the support plate 122 are detachably connected. The support plate 122 is provided with a through hole for airflow to pass through, and the air inlet end of the fan 220 is set towards the through hole.

[0048] By setting up the support plate 122 and the mounting bracket 221, the fan 220 can be modularized, facilitating the installation or disassembly of the fan 220 and effectively improving the ease of installation and removal of the fan 220. In addition, when the fan 220 is located above the evaporator 210, the lower end of the support plate 122 can also be provided with a flange to support the inclined front end of the evaporator 210, improving the installation stability of the evaporator 210.

[0049] Reference Figure 2 and Figure 4 As shown, it can be understood that the indoor unit heat exchange system 200 also includes a heater 250. Optionally, the heater 250 is configured as a PTC (Positive Temperature Coefficient) heater 250, which is characterized by high safety, good economic efficiency, simple structure, and low price; that is, a heater 250 using a positive temperature coefficient thermistor. The heater 250 is mounted on the support plate 122 and located at the air inlet end of the fan 220 and below the through hole. The heater 250 is electrically connected to the electrical control box.

[0050] By setting up a heater 250, the cold air drawn in by the fan 220 can be heated, making it convenient for users to accurately control and adjust the temperature of the cold air blown out by the indoor unit of the precision air conditioner, and improving the working stability of the precision air conditioner.

[0051] Furthermore, multiple fans 220 are provided, and the multiple fans 220 are spaced apart along the length of the housing 100. Each fan 220 is mounted on the support plate 122 via a mounting bracket 221.

[0052] Because the housing 100 adopts a flat design, multiple fans 220 can be spaced along the length of the housing 100, thereby effectively improving the air outlet efficiency of the precision air conditioner indoor unit and ensuring the air volume. At the same time, the multiple fans 220 can be modularly installed and removed through the mounting bracket 221. The fans 220 are independent of each other and will not interfere with each other, which facilitates users' later debugging, maintenance or replacement, and reduces the maintenance cost of the fans 220.

[0053] It should be added that a limiting plate 222 is also provided between the mounting brackets 221 corresponding to two adjacent fans 220. The two sides of the limiting plate 222 are fixedly connected to the two adjacent mounting brackets 221 respectively, thereby limiting the mounting brackets 221 along the length direction of the housing 100, preventing the fans 220 from shifting, and effectively improving the installation stability of the fans 220.

[0054] Reference Figure 2 and Figure 5 As shown, it can be understood that the electrical control box 300 is hinged to the housing 100. Specifically, the electrical control box 300 includes a housing 310 and a control system 320. The front side of the housing 310 is recessed to form an installation space for installing the control system 320. One side of the housing 310 is hinged to the housing 100 through a hinged pin structure. Optionally, the housing 310 can be hinged to the side wall of the second chamber 130 away from the partition 110, so that the control box 300 can open to the left relative to the compressor 230. The housing 310 can also be hinged to the partition 110, so that the control box 300 can open to the right relative to the compressor 230. The housing 310 can also be hinged to the upper or lower side wall of the second chamber 130, so that the control box 300 can open to the upper or lower relative to the compressor 230. The opening angle of the control box 300 is between 0 and 110°, so that the control box 300 can be rotated to a position that exposes the compressor 230 and the valve assembly 240.

[0055] The control box 300 is hinged to the partition 110. Users can rotate the control box 300 to hide or reveal the compressor 230 and the valve assembly 240 connected to it. This allows users to easily inspect, debug, or replace the compressor 230 and valve assembly 240 without affecting their use of the control box 300, further improving the space utilization within the second chamber 130 and enhancing the user experience. Furthermore, the second panel 170 can conceal the internal structure of the control box 300 (i.e., the control system 320), effectively improving the aesthetic appearance of the enclosure 100.

[0056] Reference Figure 2As shown, the enclosure also includes a second panel 170, which is detachably connected to the front end of the electrical control box 300. A second chamber 130 is formed between the second panel 170, the inner wall of the enclosure body, and the partition 110. A display 171 is mounted on the second panel 170 and is electrically connected to the electrical control box 300. Optionally, the display 171 can be a color high-definition screen, an LCD screen, or a smart touchscreen, which will not be elaborated further here.

[0057] By setting up a display unit 171 connected to the control box 300, the control box 300 can display the parameters detected by the first sensor group and the second sensor group on the display unit 171. Users can view various parameters of the precision air conditioner in real time through the display unit 171, such as intake temperature, exhaust temperature, intake humidity, exhaust humidity, compressor 230 pressure, etc., which makes it convenient for users to adjust the power of the fan 220, compressor 230, etc. in a timely manner, effectively improving the control accuracy of the control box 300 and further improving the user experience.

[0058] Furthermore, there is a gap between the control box 300 and the partition 110 to allow the control box 300 to rotate. In other words, there is a gap on the front side of the partition 110 to allow the control box 300 to rotate. The second panel 170 is provided with a limiting part 172, which is a protruding structure or flange structure provided on the side of the second panel 170 away from the free end of the outer shell 310. The limiting part 172 is used to fill the gap between the control box 300 and the partition 110, thereby restricting the rotation of the control box 300.

[0059] By setting the limiting part 172, after the user installs the second panel 170, the limiting part 172 of the second panel 170 can interfere with the range of motion of the partition 110, thereby limiting the rotation of the electrical control box 300, preventing the electrical control box 300 from accidentally opening and causing dust and other impurities to enter the vicinity of the compressor 230, affecting the operation of the compressor 230, and effectively improving the overall structural stability of the precision air conditioner indoor unit.

[0060] According to another embodiment of the present invention, a precision air conditioner includes an outdoor unit and a precision air conditioner indoor unit as described in the above embodiment. The outdoor unit is equipped with a condenser, and the indoor unit heat exchange system 200 of the outdoor unit is connected to the condenser through a valve assembly 240 to form a circulating refrigeration system.

[0061] Another embodiment of this utility model provides a precision air conditioner including the aforementioned precision air conditioner indoor unit. Therefore, the precision air conditioner provided in this embodiment also possesses the beneficial effects described in the above embodiments, which will not be repeated here.

[0062] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
