[0002] During long-distance transportation, trucks often encounter non-driving conditions such as traffic jams, loading and unloading, and resting. In these cases, the air conditioner is often turned on to create a comfortable environment. If the original vehicle air conditioner is turned on, the engine needs to be started simultaneously, which not only increases fuel consumption and noise, but also increases engine wear and reduces service life. With the current vigorous development of the logistics industry, parking air conditioners are also in a steady upward development stage because they are specifically designed for these special application scenarios.

[0003] Parking air conditioners mainly include parallel, split, integrated, and mobile structures. Parallel parking air conditioners are factory-installed, eliminating the need for modification, but are more expensive; split structures require connecting pipes between the internal and external units, and the external unit is mounted on the side wall of the truck, so the vibration resistance of the air conditioner often cannot meet the vibration road conditions of the vehicle; the top-mounted integrated parking air conditioner is installed on the top of the skylight and uses the original vehicle battery. It has the advantages of low energy consumption, high energy efficiency, and good shock resistance, and has gradually developed into the mainstream form; the mobile type occupies valuable space in the cab, and has the problem of hot air discharge, which limits the use scenarios.

[0025] See also Figures 1 to 6As shown, according to an embodiment of the present invention, a top-mounted integrated air conditioner is provided, comprising a chassis 1 and a top cover 2, wherein an installation space is formed between the chassis 1 and the top cover 2, within the installation space, an external fan supporting volute 31 and an internal fan cover 32 are arranged on the chassis 1, the external fan supporting volute 31 and the internal fan cover 32 divide the installation space into an outdoor cavity, a compressor cavity, and an indoor cavity, an external heat exchanger 51 and an external fan 41 are arranged in the outdoor cavity to form outdoor heat exchange of the air conditioner, a compressor 8 (specifically, for example, a variable frequency horizontal compressor) is arranged in the compressor cavity, an internal heat exchanger 52 and an internal fan 42 are arranged in the indoor cavity to form indoor heat exchange of the air conditioner, the external fan 41 is supported and connected on the external fan supporting volute 31, the external fan supporting volute 31 has a guide bottom shell 310, and an accommodation space is provided between the guide bottom shell 310 and the chassis 1, and at least part of the internal fan cover 32 is in the accommodation space. In this technical solution, at least a portion of the inner fan cover 32 is arranged in the accommodating space to form an overlap in the height direction, so that the size (such as length) of the top-mounted integrated air conditioner can be designed to be smaller, thereby making the structure of the air conditioner more compact, reducing the weight and saving material costs.

[0026] In some embodiments, along the direction of the guide bottom shell 310 approaching the external heat exchanger 51, the distance between the guide bottom shell 310 and the chassis 1 decreases in a step-like manner, that is, the distance between a section of the guide bottom shell 310 away from the external heat exchanger 51 and the chassis 1 is larger, while the distance between a section of the guide bottom shell 310 close to the external heat exchanger 51 and the chassis 1 is smaller. The position where the step changes in height should have a smooth arc surface treatment, so that it can adapt to the existing structure of the internal fan cover, axial flow fan, and chassis. If it is designed to be reduced in an arc or oblique manner, it is easy to interfere with different parts.

[0027] In some embodiments, the external fan 41 is an axial flow fan, and its rotating shaft is vertically arranged, so that the airflow can enter the outdoor air inlet 22 arranged on the side of the top cover 2 and flow through the external heat exchanger 51 and then flow out from the outdoor air outlet 21 arranged on the top surface of the top cover 2, which can reduce the height of the air conditioner. When projected on the chassis 1, the external heat exchanger 51 is L-shaped. The L-shaped external heat exchanger 51 can ensure a small height and a large heat exchange area.

[0028] See also Figure 5 and 6As shown, the compressor chamber is located at a position sandwiched between the outer fan supporting volute 31 and the inner fan cover 32, and projected onto the chassis 1, the outer fan supporting volute 31 has an arc segment 311 and an inclined segment 312, wherein the arc segment 311 is used to support the outer fan 41, and the inclined segment 312 is inclined from the indoor cavity side toward the outdoor cavity side. At this time, the compressor 8 will be arranged in such a roughly triangular compression chamber, which can improve the utilization rate of the installation space and ensure that the structure of the air conditioner is more compact.

[0029] In some embodiments, the internal fan 42 is a cross-flow fan, the internal heat exchanger 52 is projected into a V-shape on a vertical plane, the cross-flow fan is located in the mouth of the V-shape and the rotating axis of the cross-flow fan is arranged horizontally, thereby making the layout between the internal heat exchanger 52 and the cross-flow fan more reasonable and compact.

[0030] The top-mounted integrated air conditioner also includes an indoor air outlet structure 6 connected to the chassis 1, and the indoor air outlet structure 6 includes an air outlet body 60, and the air outlet body 60 is constructed with an indoor return air duct 61 and an indoor supply air duct 62, the indoor return air duct 61 is located at the air inlet side of the internal heat exchanger 52, and the indoor supply air duct 62 is located at the air outlet side of the internal heat exchanger 52. A heat insulation component 63 is provided on the air outlet body 60 corresponding to the area between the indoor return air duct 61 and the indoor supply air duct 62 to prevent the air flow in the indoor return air duct 61 and the indoor supply air duct 62 from forming condensation due to the temperature difference or increasing the air outlet temperature and reducing the cooling efficiency of the air conditioner. The heat insulation component 63 can be, for example, heat insulation cotton or foam. A control box 7 is connected to the air outlet body 60 corresponding to the area between the indoor return air duct 61 and the indoor supply air duct 62, and at least part of the control box 7 is located in the indoor supply air duct 62. In this technical solution, the control box 7 is at least partially disposed in the indoor supply air duct 62 as a heat source component, and can cool the control box 7 while cooling the indoor temperature. The internal fan cover 32 includes a return air guide housing 321 and a supply air volute 322 that are in contact with and matched with the guide bottom housing 310. The return air guide housing 321 is located at the air inlet side of the internal heat exchanger 52, and the supply air volute 322 is located at the air outlet side of the internal heat exchanger 52.

[0031] See also Figure 3As shown, at the outdoor cavity, outdoor air enters the outdoor cavity from the outdoor air inlet 22 through the external heat exchanger 51, and the treated air is blown out by the external fan 41 to form an outdoor (outside the vehicle) air circulation; at the indoor cavity, indoor air is sucked in by the internal fan 42 through the return air port 611, and is blown out through the internal heat exchanger 52 and the indoor air supply duct 62 through the air supply port 621 to form an indoor air circulation.

[0032] The roof-mounted integrated air conditioner in this technical solution can reduce the difficulty of installation, and has a more compact structure (in a specific application example, the size (such as length or width) before optimization can be shortened by about 200 mm), which can increase the number of vehicle models that can be adapted to it. It can be understood that the air conditioner with a more compact structure has a reduced weight, which can enable the vehicle using it to achieve a lightweight design and reduce energy consumption.
