Description

Technical Field

[0001] The invention relates to the technical field of air conditioning energy saving, in particular to an APM vehicle air conditioning system energy saving device. Background Art

[0002] APM (Automated People Mover System) is an urban rail transit system that is dominated by unmanned rubber-wheeled electric vehicles and runs fully automatically on dedicated lines equipped with running tracks and guide rails. In order to provide a comfortable driving experience, avoid heat stroke and discomfort, improve the air quality in the car, and prevent damage to items in the car, APM vehicles use air conditioning systems to maintain a comfortable indoor environment through cyclic compression, condensation, expansion and evaporation.

[0003] In the patent application with the authorization publication number CN216011007U and the authorization publication date 2022-03-11, entitled "An Energy-Saving Air Conditioning and Heating", the hot water in the solar water heater enters the heating box through the first outlet pipe, and then absorbs the heat in the water through the heat exchanger and enters the air conditioner through the air inlet pipe. The heat in the air conditioner enters the room through the outlet opened on the rear end face of the air conditioner, thereby achieving the effect of indoor heating. However, at night, the heat of the gas in the heating box is easily lost. In order to maintain the internal temperature of the heating box, the power consumption of the heating pipe in the heating box will increase; For example, in the patent application entitled "A water-cooled central air-conditioning energy-saving device" with the authorization publication number CN211084267U and the authorization publication date 2020-07-24, the fan is first connected to the external power supply and started to blow air into the shell. After the blown air passes through the coil, the refrigerant in the coil can cool the wind, so that cold air is blown out from the air outlet. However, in actual use, due to the combined effects of temperature difference, humidity, low surface temperature of the condenser tube, poor air flow and other factors, the surface of the coil is prone to frost, resulting in reduced heat dissipation effect and increased operating load and energy consumption of the refrigeration equipment.

[0004] Therefore, we proposed an APM vehicle air conditioning system energy-saving device to solve the above problems. Summary of the invention

[0005] 1. Technical problems to be solved by the invention: The object of the present invention is to provide an APM vehicle air conditioning system energy saving device to solve the problems in the current market raised by the above background technology.

[0007] Furthermore, the lower end surface of the external bladder body is attached to the upper end surface of the flat board box, and the cross-sectional area of ​​the flat board box is smaller than the cross-sectional area of ​​the external bladder body.

[0008] Through the above technical solution, when the external bladder is filled with gas, the gas in the flat board box can be kept warm under the action of the external bladder.

[0009] Furthermore, the water inlet end of the vacuum pump is respectively connected to the first air inlet pipe, the second air inlet pipe and the third air inlet pipe, and the water outlet end of the vacuum pump is respectively connected to the first air outlet pipe, the second air outlet pipe and the third air outlet pipe, and the first solenoid valve, the second solenoid valve, the third solenoid valve, the fourth solenoid valve, the fifth solenoid valve and the sixth solenoid valve are respectively installed in the middle of the first air inlet pipe, the second air inlet pipe, the third air inlet pipe, the first air outlet pipe, the second air outlet pipe and the third air outlet pipe.

[0010] Through the above technical solution, the vacuum pump can adjust the air volume between the refrigeration box, the storage box and the external bladder.

[0011] Furthermore, the ends of the first air inlet pipe and the first air outlet pipe are both connected to the side of the external bag body, and the ends of the second air inlet pipe and the second air outlet pipe are both connected to the side of the storage box body.

[0012] Through the above technical solution, the gas can enter and exit from the external sac and the inside of the storage box respectively.

[0013] Furthermore, the ends of the third air inlet pipe and the third air outlet pipe are respectively connected to the side of the transfer box and the lower end of the refrigeration box body, and the transfer box is fixedly installed at the upper end of the refrigeration box body, and one side of the transfer box is connected to the interior of the jet box through a pipe.

[0014] Through the above technical solution, the gas can enter the jet box from the transfer box and then be discharged from the bottom of the refrigeration box body.

[0015] Furthermore, a rotating rod is installed on the middle bearing of the transfer box, and blades are installed at equal angles on the lower end of the rotating rod, and the side parts of the blades are attached to the inner wall of the transfer box.

[0016] Through the above technical solution, when the gas flows inside the transfer box, the rotating rod can be driven to rotate by the blades distributed at equal angles.

[0023] 3. Beneficial effects: By adopting the technical solution provided by the present invention, compared with the prior art, the energy-saving device of the APM vehicle air-conditioning system of the present invention realizes the heat preservation effect of water at night in winter through the cooperation of the flat plate box and the external bladder, and reduces the heating power consumption of the flat plate box during the day to achieve energy saving. At the same time, in summer, the gas in the external bladder is used to remove the frost on the surface of the condenser tube to ensure the refrigeration efficiency of the condenser tube. The specific contents are as follows: When it is a winter night, the second solenoid valve and the fourth solenoid valve are opened, and the vacuum pump extracts the gas inside the storage box into the external bladder. The flat board box is kept warm by the external bladder to prevent the liquid temperature in the flat board box from losing too fast. When it is a winter day, the first solenoid valve and the fifth solenoid valve are opened, and the vacuum pump extracts the gas in the external bladder back to the inside of the storage box, so that the upper part of the external bladder is attached to the lower part of the external bladder, and then under the sunlight during the day, the temperature of the gas inside the flat board box is increased, the power consumption of the heating element in the flat board box is reduced, and energy saving is achieved. Then, the APM vehicle is heated through the heating box and the heating pipe; During the daytime in summer, the second solenoid valve and the fourth solenoid valve are opened, and the vacuum pump draws the gas inside the storage box into the external bag. The gas in the external bag heats up under the sun, and then the first solenoid valve and the sixth solenoid valve are opened to draw the heated gas into the transfer box. The gas then blows air to the surface of the condensation component through the nozzle arranged under the jet box, so that the frost on the surface of the condensation component can be melted. When the gas enters the transfer box, it will impact the blades distributed at equal angles, and the blades will drive the rotating rod to rotate. The rotating rod uses the transmission belt assembly to drive the reciprocating screw to rotate. The movable plate threaded on the outside of the reciprocating screw uses the limiting effect of the guide rod to drive the brush plate on the drive plate to further remove the frost on the surface of the condensation component, so as to avoid frosting on the condenser tube and reduce the operating load and energy consumption of the refrigeration equipment.

Then, the APM vehicle is heated through the heating box 1 and the heating pipe 101. During the daytime in summer, the gas inside the storage box 3 is pumped into the external bag 5. The gas in the external bag 5 heats up under the sun and is then extracted into the transfer box 7.
