Embodiment 1

At present, the air-conditioning units used in some old models of rail vehicles are still fixed-frequency air-conditioning systems. In order to meet the current operational needs, they need to be replaced or increased with variable-frequency air-conditioning systems. However, the original fixed-frequency air-conditioning units have a compact structure and layout. If variable-frequency air-conditioning units are to be replaced or increased, finding a suitable location and method for setting the electronic control components of the air-conditioning units in a small space becomes a problem that needs to be solved.

At the same time, the electronic control components will generate a lot of heat during the working process. Therefore, when setting up the electronic control components in a small space, it is also necessary to consider how to effectively dissipate the heat of the electronic control components to avoid overheating and burning or fire accidents when the electronic control components are working.

In order to solve the above problems, this embodiment provides a compact air-conditioning unit, including an electric control chamber 3 , a condensing chamber 2 and an evaporating chamber 1 .

The condensing chamber 2 is provided with components such as a compressor, a condensing fan, a condenser, and a gas-liquid separator. A vent is also provided on the outer wall of the chamber, and the condensing chamber 2 is connected to the outdoor air through the vent.

The compressor inhales low-temperature and low-pressure refrigerant vapor from the evaporation chamber 1, and is adiabatically compressed by the compressor to become high-temperature and high-pressure superheated steam, which is then pressed into the condenser for constant pressure cooling and releases heat to the cooling medium. It is then cooled into supercooled liquid refrigerant and the liquid refrigerant is transported to the evaporation chamber 1.

The evaporation chamber 1 is provided with an evaporator, a blower and other components; the liquid refrigerant in the condensation chamber 2 begins to vaporize after being heated in the low vacuum environment of the evaporator, absorbing heat energy and rapidly expanding in volume.

The liquid refrigerant evaporates in the evaporation chamber 1 and absorbs heat from the air-conditioning circulating water (air), thereby cooling the air-conditioning circulating water to achieve the purpose of refrigeration. The low-pressure refrigerant flowing out is sucked into the compressor, and the cycle works in this way.

The electric control chamber 3 is provided with electric control components such as a power conversion device and a frequency conversion control electric control box, and controls the operation of the condensation chamber 2 and the evaporation chamber 1 at the same time.

As shown in FIG. 1 and FIG. 4 , in this embodiment, the evaporation chamber 1 is set to be located right in front of the condensation chamber 2 to facilitate description of the structure of the air conditioning unit.

The condensation chamber 2 and the evaporation chamber 1 are arranged on the front and back sides respectively. Since the condensation chamber 2 releases a large amount of heat during operation and the evaporation chamber 1 absorbs a large amount of heat during operation, in order to avoid more heat transfer between the two chambers, the two chambers are separated by a partition wall 4 and are independent of each other.

Preferably, the partition wall 4 between the condensation chamber 2 and the evaporation chamber 1 is one layer or two layers. When the partition wall 4 is one layer, the condensation chamber 2 and the evaporation chamber 1 are arranged in the same chamber and separated by a common layer of the partition wall 4, and this arrangement can save materials and space; when the partition wall 4 is two layers, the condensation chamber 2 and the evaporation chamber 1 have separate partition walls 4, the condensation chamber 2 and the evaporation chamber 1 are separate chambers, the condensation chamber 2 and the evaporation chamber 1 can be separated, and the partition walls 4 of the condensation chamber 2 and the evaporation chamber 1 fit each other.

In order to enable the electric control chamber 3 to simultaneously control the operation of the condensation chamber 2 and the evaporation chamber 1 , the electric control chamber 3 penetrates the partition wall 4 and extends into the interior of the condensation chamber 2 and the evaporation chamber 1 respectively.

The electric control chamber 3 is an independent chamber having a plurality of walls, including a top wall, a bottom wall opposite to the top wall, a front side wall, a rear side wall opposite to the front side wall, a first side wall 5 , and a second side wall 6 opposite to the first side wall 5 .

Preferably, the electric control chamber 3 is a rectangular parallelepiped structure, and the top wall and the bottom wall, the front side wall and the rear side wall, and the first side wall 5 and the second side wall 6 are parallel to each other.

Since the internal space of the condensing chamber 2 and the evaporating chamber 1 is narrow and the layout is compact, the electric control chamber 3 needs to be arranged close to the wall inside the condensing chamber 2 and the evaporating chamber 1 .

The side walls of the condensing chamber 2 and the evaporating chamber 1 receive the internal space of the electric control chamber 3. At this time, the electric control chamber 3 does not need to be provided with a first side wall 5. The connection between the side walls of the condensing chamber 2 and the evaporating chamber 1 defines the first side wall 5. This arrangement can save space and material costs.

Alternatively, the electric control chamber 3 is independently provided with a first side wall 5 , and the first side wall 5 is in contact with the side walls of the condensation chamber 2 and the evaporation chamber 1 . This arrangement facilitates adjustment of the position of the electric control chamber 3 .

Similarly, the bottom walls of the condensing chamber 2 and the evaporating chamber 1 receive the internal space of the electric control chamber 3, and the connection on the bottom walls of the condensing chamber 2 and the evaporating chamber 1 defines the bottom wall of the electric control chamber 3; or, the electric control chamber 3 is separately provided with a bottom wall, and the bottom wall of the electric control chamber 3 is in contact with the bottom walls of the condensing chamber 2 and the evaporating chamber 1.

The second side wall 6 receives the partition wall 4 and is tightly connected to the partition wall 4 .

The electronically controlled components in the electronically controlled chamber 3 will generate a large amount of heat during operation. In order to continuously and effectively dissipate the heat of the electronically controlled chamber 3, the electronically controlled chamber 3 is at least partially disposed indoors. An air inlet 7 is disposed on the first side wall 5. The electronically controlled chamber 3 is connected to the indoor space through the air inlet 7 disposed on the first side wall 5.

In order to realize continuous ventilation of the electric control chamber 3, an air outlet 8 is provided on the second side wall 6, and the electric control chamber 3 is connected with the evaporation chamber 1 through the air outlet 8 provided on the second side wall 6. At this time, the indoor cold air enters the electric control chamber 3 through the air inlet 7 on the first side wall 5, cools down the electric control components in the electric control chamber 3, and the generated hot air enters the evaporation chamber 1 through the air outlet 8 on the second side wall 6. The evaporation chamber 1 cools down the incoming hot air and passes it into the room. The cold air passed into the room will enter the electric control chamber 3 through the air inlet 7 again. This cycle continues, so that the electric control chamber 3 has a continuous and stable circulating heat dissipation wind, and the continuous cooling of the electric control chamber 3 can be realized at this time.

Optionally, the indoor room is a house, a rail vehicle driver's room, a rail vehicle passenger room, etc. Taking the rail vehicle driver's room as an example, since the temperature in the operating rail vehicle driver's room is relatively constant, generally a temperature suitable for human activities, the electric control chamber 3 is connected to the indoor room, and the electric control chamber 3 can obtain continuous and stable cold air.

Preferably, due to the close layout and numerous electric control components in the electric control chamber 3, in order to avoid untimely heat dissipation caused by insufficient flow of heat dissipation air, the orthographic projection of the air inlet 7 on the second side wall 6 at least partially overlaps with the air outlet 8. This arrangement allows part of the heat dissipation air to quickly pass through and flow out of the electric control chamber 3 after entering the electric control chamber 3, and at this time, it quickly provides space for the cold air behind to enter, so that the heat dissipation of the electric control chamber 3 is more timely and rapid.

The top walls of the condensing chamber 2 and the evaporating chamber 1 receive the internal space of the electric control chamber 3, and the receiving portion defines the top wall of the electric control chamber 3. Alternatively, the electric control chamber 3 is provided with a top wall alone, and the top wall of the electric control chamber 3 is in contact with the top walls of the condensing chamber 2 and the evaporating chamber 1.

Optionally, the top wall of the electric control chamber 3 is provided with an air inlet 7 and/or an air outlet 8, and the electric control chamber 3 is connected to the outdoors through the air inlet 7 and/or the air outlet 8 on the top wall.

An inclined wall is provided on the top of the evaporation chamber 1 , and the inclined wall extends from the top wall of the evaporation chamber 1 to the front side wall connected to the evaporation chamber 1 .

The extending starting position of the inclined wall on the top wall of the evaporation chamber 1 coincides with the front end of the top wall of the electric control chamber 3 , or the extending starting position of the inclined wall on the top wall of the evaporation chamber 1 is located in front of the top wall of the electric control chamber 3 .

The evaporation chamber 1 located in front of the front side wall of the electric control chamber 3 is entirely arranged indoors, and the evaporation chamber 1 and the electric control chamber 3 located behind the front side wall of the electric control chamber 3 are at least partially arranged indoors.

Preferably, all the air inlets 7 on the first side wall 5 are arranged indoors.

The electric control chamber 3 is connected to the evaporation chamber 1 through the circulation air outlet 9 provided on the second side wall 6.

The circulating air port 9 includes a circulating air inlet 11 and a circulating air outlet 10 , and is used to realize the circulation of air between the evaporation chamber 1 and the electric control chamber 3 .

In the air conditioning unit provided in this embodiment, the air outlet 8 is the circulating air outlet 10, and the two have the same structure.

Embodiment 3

As shown in FIG3 , as another implementation of the arrangement of the air inlet 7 and the air outlet 8 of the electric control chamber 3 in the first embodiment, in the compact air conditioning unit provided in this embodiment, the first side wall 5 and the second side wall 6 of the electric control chamber 3 do not need to be provided with the air inlet 7 and the air outlet 8. Only the circulation air outlet 9 is provided on the second side wall 6, and the electric control chamber 3 is connected with the evaporation chamber 1 through the circulation air outlet 9 provided on the second side wall 6.

The circulating air port 9 includes a circulating air inlet 11 and a circulating air outlet 10 , and is used to realize the circulation of air between the evaporation chamber 1 and the electric control chamber 3 .
