Problems solved by technology

Because the condenser is close to the condensing air inlet of the shell, sand and dust will adhere to the condenser under the action of rain and snow. After long-term operation, the heat exchange efficiency of the condenser will gradually decrease, which will seriously affect the refrigeration of the air conditioning unit. efficiency, and it is easy to cause damage to the air conditioning unit. Moreover, since the dust is collected in the dust box, it is necessary to clean the dust box frequently, resulting in a waste of manpower and material resources.

Embodiment 1

[0031] Such as Figure 1 to Figure 3 As shown, the rail vehicle roof-mounted air-conditioning unit with wind and sand protection function according to the present invention includes a shell 1, and the two sides of the shell 1 are provided with a long mounting seat 2, and the mounting seat 2 is an aluminum profile or a stainless steel structure , the mounting seat 2 is fixedly installed on the vehicle body (not shown in the figure) by the bolt 3, the lower half of the housing 1 is seated inside the vehicle body, and only the upper half is exposed outside the vehicle body.

[0032] Such as figure 1 As shown, in this embodiment, inside the housing 1, it is divided into an evaporation chamber 9, a condensation chamber 10, a fresh air chamber 11 and a waste discharge chamber 12. The evaporation chamber 9 is arranged on the left side of the condensation chamber 10, and the fresh air chamber 11 and The waste discharge chamber 12 is arranged on the right side of the condensation cham...

Embodiment 2

[0046] The difference from Embodiment 1 is that a second partition (not shown in the figure) is set between the condensing air inlet 18 and the exhaust outlet 19, and the second partition surrounds the side cover 4 on this side. The space is divided into two relatively independent condensation ventilation spaces and waste exhaust ventilation spaces. The exhaust gas in the compartment enters the waste exhaust cavity 12 through the waste exhaust inlet under the action of the exhaust exhaust fan, and then passes through the waste exhaust cavity on the housing 1. The opening enters the waste exhaust ventilation space on this side, and finally discharges out of the vehicle from the waste exhaust air outlet 19 on the side plate 6 . The air outside the vehicle only enters the condensation ventilation space from the three condensation air inlets 18 on this side, and then enters the condensation chamber 10 through the condensation chamber opening on the housing 1 .

Abstract

The invention relates to an overhead air conditioning unit with a sand wind preventing function and for a railway vehicle. The overhead air conditioning unit comprises a shell, the shell is fixedly mounted on a vehicle body, and side cover plates are fixedly mounted on two sides of the shell respectively. Each side cover plate is of a side-opening structure enclosed by a top plate, a side plate and a bottom plate, the sides of each top plate and each bottom plate are fixedly connected, each side plate is inclined towards the outer side, each bottom plate is provided with a sand outlet close to an inclined angle of the bottom plate and the side plate, and each side plate is provided with a condensation air inlet and/or fresh air inlet and/or exhaust outlet. The condensation air inlets and/or fresh air inlets and/or exhaust outlets are respectively communicated with a condensation cavity, a fresh air cavity and an exhaust cavity in the shell through a condensation cavity opening, a fresh air cavity opening and an exhaust cavity opening in the shell. By the aid of the side cover plates, most sand is effectively stopped outside the air conditioning unit, fine dust entering the side cover plates can be collected and discharged, so that sand is effectively prevented from entering the vehicle body from the air conditioning unit, air in carriages is kept fresh, and comfort of passengers is improved.

Description

technical field [0001] The invention relates to a rail vehicle air conditioner unit, in particular to a rail vehicle roof-mounted air conditioner unit with the function of preventing wind and sand, and belongs to the technical field of rail vehicle air conditioner manufacturing. Background technique [0002] When rail vehicles often operate in areas with severe sand and dust weather, sand and dust will enter the interior of the compartment through the fresh air inlet of the air conditioning unit, causing the dust concentration in the compartment to exceed the standard, affecting the air quality in the compartment, and the dust will also be released with the condensed air. Enter the air conditioner condenser, causing the condenser to be blocked, thus affecting the cooling effect of the air conditioner and reducing the ride comfort. In order to ensure the air quality in the compartment and improve the ride comfort, in addition to installing a filter device at the fresh air inl...
