The utility model relates to an air conditioner drainage system, in particular to air conditioning unit drainage system for vehicle relates to a rail vehicle who installs this drainage system simultaneously.
Background
In order to adjust the temperature and humidity in the vehicle cabin, an air conditioning unit is generally installed on the vehicle, and the air conditioning unit which is generally adopted at present is of a unit overhead type structure and is integrally installed above the vehicle roof. An air conditioning platform is arranged at the top of the vehicle, and the air conditioning unit is integrally arranged on the air conditioning platform.
The unit overhead type air conditioning unit is divided into an indoor cavity and an outdoor cavity by a partition plate, an evaporator, an evaporation fan and the like are installed in the indoor cavity, a water receiving tray is installed below the evaporator, and condensed water generated during the refrigeration operation of the air conditioner is collected in the water receiving tray below the evaporator and then is discharged by a drainage system of the air conditioner.
At present, there are two common solutions to the problem of condensate water discharge:
one method is to drain the condensate directly under the vehicle through a condensate drain pipe connected to a water pan, but this method has the following disadvantages: firstly, the welding seam of the water pipe joint of the side wall of the vehicle body has water leakage hidden trouble and is not easy to replace; a condensation drain pipe is additionally arranged on the side wall of the vehicle body, the weight of the vehicle is increased, and the higher requirement of lightening and minimizing the vehicle cannot be met; and thirdly, a rubber hose joint is required to be added at the joint of the pipelines, so that the overhaul and maintenance cost is increased.
The other method is to adopt a mode of air conditioner condensed water scattering, namely, the air conditioning unit directly discharges the condensed water onto an air conditioning platform (roof), and the condensed water discharged onto the air conditioning platform flows into rain eaves at two sides of the vehicle body and then flows down from two ends of the vehicle body. However, the scattered arrangement method has the following disadvantages: the air conditioner condensate water flows on the air conditioner platform in disorder, so that splashing phenomenon exists, the vehicle body is easy to corrode, meanwhile, if the sealing is not good, leakage can be generated, the normal running of the vehicle can be seriously influenced, and the normal riding is directly influenced.
In order to solve the problems existing in the scattered drainage mode, patent No. 201510108451.1 discloses a condensate water drainage system of an air conditioning unit of a monorail vehicle, which comprises an outer drainage pipe for draining condensate water of the air conditioning unit, a drainage tank arranged above the top of a vehicle body and vehicle body rain eaves positioned on two sides of the top of the vehicle body, wherein the outer drainage pipe is arranged outside the air conditioning unit and extends out in the transverse direction of the vehicle body, the drainage tank is correspondingly arranged below the outer drainage pipe, the other end of the outer drainage pipe is connected with a water collecting box arranged inside the air conditioning unit, the water collecting box is connected with a water collecting tray through an inner drainage pipe, and the vehicle body rain eaves and a vehicle roof groove formed in the side wall of the top. After being collected in the water receiving tray, the condensed water generated by the air conditioning unit sequentially passes through the inner water discharging pipe, the water collecting box and the outer water discharging pipe, finally flows out of one side of the water discharging groove and is collected into the vehicle roof groove, and the condensed water flows to the two ends of the vehicle body again, so that the condensed water is discharged along the end parts of the two ends of the monorail vehicle.
In this comdenstion water drainage system, the setting of water drainage tank not only acts as the comdenstion water conservancy diversion structure between outer drain pipe and the roof slot, still provides the place of buffering, collecing for outer drain pipe exhaust comdenstion water, has realized concentrated drainage to a certain extent, can avoid the drainage to splash. However, in the drainage system, a certain distance is still left between the drainage groove and the roof ditch, condensed water flowing out of the drainage groove needs to flow over the side wall of the top of the vehicle body to enter the roof ditch, the possibility of splashing of the drained water still exists in the flowing-out process of the condensed water, and meanwhile, the problem of disordered flowing also exists, so that the drainage efficiency is influenced.
