DETAILED DESCRIPTION

[0017] refer to Figures 1 to 4 The outdoor unit for a refrigerator device according to an embodiment of the present invention is introduced, which includes: a first unit 1, the first unit 1 includes a compressor, such as a single compressor or two (or more) compressors 911, 912 in parallel; a second unit 2, the second unit 2 includes a condenser, such as a condenser including two sets of coils 221, 222 and two fans 23. The outdoor unit can be installed in a first mode or a second mode. Figure 1 In the first mode shown, the first unit 1 and the second unit 2 are installed adjacent to each other and connected to each other through fasteners, and the first unit 1 and the second unit 2 are connected by a first fluid pipeline passing through the adjacent surface between the first unit and the second unit; in the second mode, the first unit 1 and the second unit 2 are installed at a first position and a second position spaced apart, respectively, and the first unit 1 and the second unit 2 are connected by a second fluid pipeline extending between the first position and the second position. Therefore, the outdoor unit according to the embodiment of the present invention provides two installation modes, wherein in the first installation mode, the first unit 1 with a compressor and the second unit 2 with a condenser are arranged in combination, and the first mode is suitable for working conditions with better installation conditions, while in the second mode, the first unit 1 and the second unit 2 are arranged at different positions, and the installation mode is suitable for situations where installation conditions are limited, for example, the first unit 1 can be installed at a first position near the indoor load and with poor ventilation conditions, and the second unit 2 can be installed at a second position with better ventilation conditions but farther away. Therefore, the outdoor unit according to the embodiment of the present invention provides installation flexibility, so that the outdoor unit can be flexibly applied to various installation conditions. For example, the outdoor unit may be transported to the site in a first installation mode, and then installed in the first mode or the second mode according to site conditions.

[0018] In some embodiments, reference Figure 3 and Figure 4, the first unit 1 further includes a recuperator 96, and the recuperator 96 includes a first pipe 961 and a second pipe 962. The first unit 1 includes: a first outlet port 120 connected to the exhaust ports 913, 915 of the compressor, a first inlet port 121 connected to the first end of the first pipe 961 of the recuperator 96; a second outlet port 127 connected to the second end of the first pipe 961 of the recuperator 96; and a second inlet port 128 connected to the first end of the second pipe 962 of the recuperator 96; the second end of the second pipe 962 of the recuperator 96 is connected to the suction ports 914, 916 of the compressor, the first inlet port 121 and the first outlet port 120 are respectively used to connect to the condenser of the second unit 2, that is, the inlet and outlet of the condenser, and the second inlet port 128 and the second outlet port 127 are respectively used to connect to the indoor load, that is, the indoor load includes a throttling unit and an evaporator. The first unit 1 of the outdoor unit according to the embodiment of the present invention is provided with a heat recovery heat exchanger 96, which is particularly important in the second mode. Specifically, when installed in the second mode, since the pipeline between the first unit 1 and the second unit 2 may be long and exposed to the outdoors, this will cause the refrigerant from the condenser outlet to partially evaporate before passing through the long pipeline to reach the first unit 1, thereby generating a two-phase refrigerant. The heat exchange with the refrigerant returned in the second pipeline 962 in the heat recovery heat exchanger 96 will increase the subcooling of the refrigerant in the first pipeline 961 and the superheating of the refrigerant in the second pipeline 962, thereby avoiding or at least alleviating the impact of the two-phase refrigerant being delivered to the indoor load and affecting the performance of the indoor load.

[0019] In some embodiments, the first unit 1 includes a first unit housing that is substantially in the shape of a cube, which substantially includes a top 12, a peripheral wall and a bottom wall. An openable double-leaf door 11 may be provided at one end of the peripheral wall for maintenance purposes. Figure 2 and Figure 3 As can be seen, the first outlet port 120 and the first inlet port 121 are arranged at the top 12 of the first unit shell. Compressors 911, 912, a heat recovery heat exchanger 96 and an optional oil separator 92, an oil reservoir 93, a refrigerant reservoir 94, and a gas separator 95 are also arranged in the first unit shell.

[0020] In some embodiments, see Figure 4, wherein the second unit 2 is marked by a box, and the rest of the outside of the box belongs to the first unit 1. In this embodiment, the compressor exhaust ports 913, 915 of the two parallel compressors 911, 912 (the number of compressors may be changed as an alternative) are connected to the oil separator 92, and the gas outlet 921 of the oil separator is connected to the first outlet port 120, which includes two parallel first outlet ports 120 (the number of first outlet ports 120 may be changed as an alternative) in the illustrated embodiment, the oil outlet 922 of the oil separator 92 is connected to the oil reservoir 93, and the oil reservoir 93 is further connected to the compressor suction ports 914, 916 and / or the compressor suction manifold 917 via a capillary tube, and the compressor suction ports 914, 916 are connected to the second end of the second pipe 962 of the heat exchanger 96 via the gas separator 95, and the first end of the first pipe 961 of the heat exchanger 96 is connected to the first inlet port 121 via the refrigerant storage liquid 94.

[0021] In some embodiments, Figure 3 As shown, the second unit 2 includes a bottom plate, V-shaped heat exchange coils 221, 222 on the bottom plate, and two fans 23 above the V-shaped heat exchange coils 221, 222 (alternatively, the number of fans 23 can be changed). When installed in the first mode, the bottom plate of the second unit is installed adjacent to the top 12 of the first unit. The fan 23 includes a motor, blades, a grille, etc. When it is working, it draws air so that the airflow passes through the heat exchange coils 221, 222 from both sides of the V-shaped heat exchange coils 221, 222, and then dissipates from the top after heat exchange with the refrigerant in the heat exchange coils 221, 222. Through the structure of the V-shaped heat exchange coils and the top fans of the second unit 2, the operation of the second unit 2 will not be hindered even when the second unit 2 is installed above the first unit 1 in the first mode.

[0022] In some embodiments, the V-shaped heat exchange coil includes a first coil portion 221 and a second coil portion 222 that are independent of each other. The first coil portion 221 and the second coil portion 222 are respectively plate-shaped and arranged in a V-shape. The first coil section 221 and the second coil section 222 each include an independent air intake manifold 226, which extends from the bottom to the top along one side of the first coil section 221 and the second coil section 222 and each includes an independent air intake port. In the first mode, each air intake port is connected to the first outlet port 120 of the first unit through an L-shaped pipeline 31, and the return liquid of the first coil section 221 and the second coil section 222 is merged through the return liquid manifold 224 and connected to the return liquid main pipe 225. The return liquid main pipe 225 is roughly T-shaped and includes a vertically oriented portion, which has a downward return liquid port. In the first mode, the return liquid port is connected to the first inlet port 121 of the first unit 1, which is also vertically oriented, so that the liquid refrigerant can return to the first unit 1 by gravity.

[0023] In some embodiments, the bottom plate of the second unit includes a bottom plate body 21 supporting the bottom of the V-shaped heat exchange coil and bottom plate frames 211, 212 outside the bottom plate body 21. In the embodiment shown, the bottom plate frame is substantially rectangular and includes a horizontal frame 212 and a vertical frame 211. In addition, vertical beams 223 are provided at the four corners of the bottom plate frame for structural stability. Figure 1 As shown, in some embodiments, the second unit 2 may further include grid plates 29 on both sides connected between the bottom plate frame and the top of the V-shaped heat exchange coil and end plates 28 at both ends, so that the second unit has a roughly cubic shape. The size and shape of the bottom plate frame of the second unit 2 are substantially consistent with the size and shape of the top 12 of the first unit 1, so that after the first unit 1 and the second unit 2 are assembled in the first mode, the outdoor unit as a whole is roughly in the shape of a cube, so that the outdoor unit assembled in the first mode can be placed in a regular outdoor installation space.

[0024] In some embodiments, Figure 2 As shown, when installed in the first mode, a plurality of bolts 3 can connect the frame of the bottom plate of the second unit to the first unit. Alternatively, a plurality of bolts can also be used to connect the bottom plate body of the second unit 2 and the first unit. The grid plate 29 can be installed after the first unit and the second unit are assembled by a plurality of bolts 3. In addition, when installed in the first mode, the first unit 1 and the second unit 2 can be directly plugged and assembled through a short fluid pipeline, such as the L-shaped fluid pipeline 31 shown in the figure. In addition, the control cable of the fan of the condenser of the second unit 2 can be easily connected between the first unit and the second unit. In other embodiments, when the first unit 1 and the second unit 2 are installed in the second mode, the second unit 2 can be configured with an electric control module 27. At this time, the electrical circuit between the first unit 1 and the second unit 2 can be integrated into a single electrical cable and connected to the electric control module 27 of the second unit, thereby facilitating the regularization and arrangement of long-distance electrical circuits. In some embodiments, when installed in the second mode, the electrical cables and fluid pipelines can also be integrated into an integrated line. In some embodiments, as Figure 6 and Figure 7 As shown, the top of the first unit 1 may have a positioning feature 17 that matches the bottom frame or bottom body of the second unit, thereby facilitating the assembly of the two. According to other embodiments, a refrigerator device is also provided, the refrigerator device comprising the outdoor unit according to various embodiments.

[0025] The outdoor unit according to the present invention can be transported to the site in the first mode (alternatively, it can also be transported in parts), and then it is determined to be installed in the first mode or the second mode based on the conditions on site. The installation in the first mode only requires welding of the corresponding pipes, installation of fasteners and electrical lines, and the installation in the second mode can consider using a single mixed line including electrical welding and fluid pipelines to be reasonably arranged and connected between the first unit 1 and the second unit 2. It should be understood that the outdoor unit is usually arranged outdoors, but this is not restrictive. In fact, the outdoor unit is only intended to indicate that it can be in a different space relative to the indoor load, but it does not have to be exposed to the outdoor environment. For example, the first unit 1 can also be arranged in a space indoors that is different from the indoor load, or the first unit 1 and the second unit 2 are arranged together in a space indoors that is different from the indoor load.

[0026] The specific embodiments described above in this application are only for more clearly describing the principles of this application, wherein each component is clearly shown or described to make the principles of the present invention easier to understand. Without departing from the scope of this application, those skilled in the art can easily make various modifications or changes to this application. Therefore, it should be understood that these modifications or changes should be included in the scope of patent protection of this application.
