In addition, the refrigerating unit generally adopts a narrow condenser, which has low efficiency.
还有，玻璃门制冷设备在使用过程中玻璃门易产生凝露，影响显示效果，现有的玻璃门制冷设备，多采用的是门体玻璃镀膜，增加玻璃层数或门体充氩气等方式防止凝露产生。在这种情况下，门体成本较高，而且会因增加多层玻璃使门体过重，而使制冷设备重心前移，放置不稳。In addition, during the use of glass door refrigeration equipment, the glass door is prone to condensation, which affects the display effect. The existing glass door refrigeration equipment mostly uses glass coating on the door body, increasing the number of glass layers or filling the door body with argon, etc. way to prevent condensation. In this case, the cost of the door body is high, and the door body will be too heavy due to the addition of multiple layers of glass, so that the center of gravity of the refrigeration equipment will move forward and the placement will be unstable.
另外，还有的制冷机组虽然同时具有除凝露及提供制冷循环的功能，但其与制冷设备呈一体化设置，装卸及维修都很麻烦。In addition, although some refrigerating units have the functions of removing condensation and providing refrigeration cycles, they are integrated with the refrigerating equipment, and the installation, disassembly and maintenance are very troublesome.

下面分别对冷凝器系统30及蒸发器系统20的循环过程进行说明。The circulation process of the condenser system 30 and the evaporator system 20 will be described respectively below.
冷凝器系统30的气体的具体循环过程为：外部的空气经过位于壳体40的前部和底部的冷凝器用进风口43（图2所示的A和A’路径），进入冷凝器系统30的空间中，然后进入冷凝器31，经上述的制冷循环系统处理后，部分由冷凝器31排出并在冷凝器风机32的作用下，其中的大部分由位于壳体40的倒角部45的冷凝器用出风口46向上吹出而吹向箱体1的玻璃门体表面（图2所示的C路径），由于该气体为热气，因此能够去除玻璃门体表面形成的凝露，少量气体经由上述风道由壳体40后部的出风口45排出（图2所示的B路径）。The specific circulation process of the gas in the condenser system 30 is as follows: the external air passes through the condenser air inlets 43 located at the front and bottom of the housing 40 (paths A and A' shown in FIG. 2 ), and enters the condenser system 30 space, and then enter the condenser 31, after being processed by the above-mentioned refrigeration cycle system, part of it is discharged from the condenser 31 and under the action of the condenser fan 32, most of it is condensed by the chamfer 45 located at the shell 40 The device uses the air outlet 46 to blow upwards to the surface of the glass door of the box body 1 (path C shown in Figure 2). Since the gas is hot gas, it can remove the condensation formed on the surface of the glass door, and a small amount of gas passes through the above-mentioned wind. The path is discharged from the air outlet 45 at the rear of the casing 40 (path B shown in FIG. 2 ).
蒸发器系统20的气体的具体循环过程为：在蒸发器风机22的作用下，将经上述的制冷循环系统处理后并由蒸发器21排出的冷气，经由蒸发器用出风口41沿箱体1一侧的侧壁吹入箱体内部（图2所示的D路径），并经阻挡（例如，部分受到箱体内的搁物板等的阻挡）后（图2所示的E路径）由箱体1另一侧的侧壁返回（图2所示的F路径）蒸发器系统20中。The specific circulation process of the gas in the evaporator system 20 is as follows: under the action of the evaporator fan 22, the cold air that has been processed by the above-mentioned refrigeration cycle system and discharged from the evaporator 21 passes through the air outlet 41 of the evaporator along the box body 1. The side wall of the side blows into the interior of the box (D path shown in Figure 2), and is blocked (for example, partially blocked by the shelf board in the box) (E path shown in Figure 2) by the box 1 The side wall on the other side returns (path F shown in FIG. 2 ) to the evaporator system 20.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of the present invention. within the scope of protection.
例如，在本实施方式中，在壳体40的后部设置有出风口47，但并不局限于此，也可取消该出风口，改为气体全部由该冷凝器用出风口46吹向玻璃门体，该结构能够使制冷设备靠墙壁设置，有助于提高使用面积。For example, in this embodiment, an air outlet 47 is provided at the rear portion of the housing 40, but it is not limited to this, and the air outlet can also be eliminated, and all the gas is blown to the glass door by the air outlet 46 of the condenser. This structure enables the refrigeration equipment to be placed against the wall, which helps to increase the usable area.
