Description

Technical Field

[0001] The utility model belongs to the field of passenger car air conditioners, and in particular relates to an air conditioning water circulation system suitable for passenger cars. Background Art

[0002] my country is one of the countries with water shortage, especially fresh water. Due to the large population in my country, the per capita water consumption is very low. In addition, the global temperature rise in recent years has made the existing fresh water resources become less and less. Therefore, in today's water shortage, we should upgrade technology from all aspects to improve water utilization and protect water resources.

[0003] Buses are a widely used means of transportation, especially in my country, where medium-distance travel mostly takes buses as the primary mode of transportation. Whether in summer or winter, the air conditioner needs to be turned on when riding in a bus, which will produce a certain amount of liquid water after long-term operation. Often, this liquid water needs to be discharged from the vehicle through a drainage device, and cannot be collected, treated, or recycled, resulting in a waste of water resources.

[0004] Liquid water is one of the main components of the normal and safe operation of buses. At present, the water produced by bus air conditioning needs to be discharged outside the vehicle, resulting in a waste of resources. If it can be collected for secondary treatment so that it can be recycled, the utilization rate of water resources will be improved, thereby achieving the purpose of protecting water resources. At the same time, it will also accelerate the process of green and energy-saving transformation of automobiles.

[0005] As for the actual application: the liquid water produced by the existing vehicle air conditioner is discharged out of the vehicle through the drainage device, and there is no mature device for collecting, treating and recycling the liquid water of the vehicle air conditioner on the market.

[0006] Traditional bus air conditioners will produce a certain amount of condensed water when used for a long time, which is discharged out of the car through the drainage system and cannot be recycled, resulting in a waste of water resources.

A front rainwater storage tank 7, a rear rainwater storage tank 17 and an air conditioning assembly 10 are installed at the top front end of the vehicle, and the air conditioning assembly 10 is located between the front rainwater storage tank 7 and the rear rainwater storage tank 17.

[0029] The front water tank 1, the front rainwater storage tank 7, the rear rainwater storage tank 17 and the rear water tank 23 are connected in series in sequence through pipelines. Specifically, the front water tank 1 is connected to the front rainwater storage tank 7 through the front water pipe 43, the rear water tank 23 is connected to the rear rainwater storage tank 17 through the rear water pipe 44, and the front rainwater storage tank 7 and the rear rainwater storage tank 17 are connected through the rainwater collecting pipe 11; and the front water pipe 43, the rainwater collecting pipe 11 and the rear water pipe 44 are connected in sequence.

[0030] The first filter 3 and the front water tank one-way valve 29 are installed on the front water pipe 43 between the front water tank 1 and the front rainwater storage tank 7. A front water tank water level detector 2 is installed inside the front water tank 1, and a water level detector (not shown in the figure) is also installed inside the front rainwater storage tank 7. When the water inside the front rainwater storage tank 7 reaches a certain amount, the front water tank one-way valve 29 can be opened to allow the water inside the front rainwater storage tank 7 to flow into the first filter 3 for secondary filtration and then flow into the front water tank 1 for use by the entire vehicle.

[0031] A rear water tank check valve 25 is installed on the rear water pipe 44 between the rear water tank 23 and the rear rainwater storage tank 17. A rear water tank water level detector 26 is installed inside the rear water tank 23, and a water level detector (not shown in the figure) is also installed inside the rear rainwater storage tank 17. When the water inside the rear rainwater storage tank 17 reaches a certain amount, the rear water tank check valve 25 can be opened to allow the water inside the rear rainwater storage tank 17 to flow into the rear water tank 23 for use by the entire vehicle.

[0032] The air conditioning assembly 10 is located on the top of the vehicle body, and a front drain port 12 and a rear drain port 15 are respectively arranged at the front and rear of the air conditioning assembly 10, wherein the front drain port 12 is connected to the rainwater collecting pipe 11 through a three-way valve 13, and the rear drain port 15 is directly connected to the rainwater collecting pipe 11. In this way, the front and rear drain ports of the air conditioning assembly 10 are connected to the front water tank 1 and the rear water tank 23 by using the rainwater collecting pipe 11 and the three-way valve 13 in combination.

[0033] An air conditioning drainage electromagnetic one-way valve 14 is installed between the front drainage port 12 and the rear drainage port 15, a front drainage one-way valve 9 is installed between the front water tank 1 and the front drainage port 12, and a rear drainage one-way valve 16 is installed between the rear drainage port 15 and the rear water tank 23.

[0034] The front rainwater storage box 7 is also connected to the front drainage device 5 through a rainwater discharge pipeline, and a front rainwater discharge one-way valve 4 is arranged at the rainwater outlet of the front rainwater storage box 7, and a front drainage one-way valve 6 is arranged on the water inlet side of the front drainage device 5.

The rear rainwater discharge one-way valve 18 and the rear drainage one-way valve 19 are both provided on the rainwater discharge pipeline.

[0036] When the amount of water in the front water tank 1 is insufficient, the front drainage check valve 9 is opened, the front rainwater external discharge check valve 4 and the air conditioning drainage electromagnetic check valve 14 are closed, so that the condensed water generated by the air conditioning assembly 10 is discharged into the first filter 3, and is stored in the front water tank 1 after being filtered. When the amount of water in the rear water tank 23 is insufficient, the rear drainage check valve 16 is opened, the air conditioning drainage electromagnetic check valve 14 and the rear rainwater external discharge check valve 18 are closed, so that the filtered water in the rear rainwater storage box 17 flows into the rear water tank 23 through the rainwater collection pipe 11 for storage, and is filtered by the filtering device during the water flow process, thereby improving the cleanliness of water resources.

[0037] It should be noted that the front rainwater storage tank 7 and the rear rainwater storage tank 17 are rectangular in shape, and their bottom surfaces match the vehicle, but the shape of the water tank is not limited to these two positions, and the shape is not limited to a rectangle.

When the temperature of the machine room is too high, the engine sprayer 21 can be turned on to make the water inside the rear water tank 23 appear in a mist form and spray toward the machine room, thereby lowering the temperature of the entire machine room.

[0041] An air conditioning water circulation control method applicable to a passenger car includes the following control modes:

[0042] First: when the water level in the water tank 1 is insufficient, open the front water drainage check valve 9, close the front rainwater discharge check valve 4 and the air conditioning drainage electromagnetic check valve 14, so that the water inside the front rainwater storage box 7 and the condensed water generated by the air conditioning assembly 10 flow into the front water tank 1 for storage;

[0043] Second: when there is enough water in the front water tank 1, open the front rainwater discharge check valve 4, the front water discharge check valve 6 and the front water discharge check valve 9, close the front water tank check valve 29, and allow the condensed water generated by the front rainwater storage box 7 and the air conditioning assembly 10 to be discharged outside the vehicle through the front water discharge device 5;

[0044] Third: When the water level in the rear water tank 23 is insufficient, open the rear drainage check valve 16, the rear rainwater discharge check valve 18 and the rear water tank check valve 25, and close the rear drainage check valve 19, so that the condensed water generated by the rear rainwater storage tank 17 and the air conditioning assembly 10 flows into the rear water tank 23 for storage;

[0045] Fourth: When the water in the rear water tank 23 is sufficient, the rear rainwater discharge check valve 18 and the rear water discharge check valve 19 can be opened, and the rear water tank check valve 25 can be closed, so that the condensed water generated by the rear rainwater storage tank 17 and the air conditioning assembly 10 can be discharged outside the vehicle through the rear water discharge device 20;

[0046] Fifth: When the water in the front water tank 1 and the rear water tank 23 is sufficient, close the rear water tank check valve 25 and the front water tank check valve 29, open the other solenoid valves, and discharge the excess water out of the vehicle through the front drainage device 5 and the rear drainage device 20;

[0047] Sixth: When the water volume in the front water tank 1 and the rear water tank 23 is insufficient, the front drainage check valve 6 and the rear drainage check valve 19 can be closed, and other solenoid valves can be opened to allow the water in the front and rear water tanks and the condensed water generated by the air-conditioning assembly 10 to flow into the water tank through the pipeline for storage.

[0048] like Figure 2 As shown, further, two rainwater collecting pipes 11 are arranged on the roof, and the two are arranged symmetrically. The rainwater collecting pipe 11 is connected to at least one condenser spray pipe, and a condenser sprayer 41 is arranged at the end of each condenser spray pipe, and the condenser sprayer 41 faces the fan cover of the condenser assembly 30, and a condenser spray one-way valve 40 is arranged on the condenser spray pipe. For the air conditioning assembly, the condenser assembly 30 is located in front of the evaporating fan assembly 31, and when the air conditioning works for a long time, the temperature of the fan cover on the condenser assembly 30 will increase, and the temperature of the internal fan compartment will also increase. Therefore, a condenser spray one-way valve 40 and a condenser sprayer 41 are added on the top of the fan cover. Through the rainwater collecting pipe 11, the condensed water generated by the air conditioning assembly 10 can be directly utilized to spray it onto the fan cover in an atomized state, thereby achieving the purpose of cooling the fan cover and the condensation chamber. A fan cover temperature sensor 39 is installed near the fan cover, which can monitor the temperature of the condensing chamber in real time and feed back to the main control system. When the temperature reaches the preset value, the condenser spray check valve 40 and the condenser sprayer 41 can be automatically opened to achieve the cooling function. When the temperature does not reach the preset value, it is in a closed state.

[0049] Furthermore, a condensate water pipeline 45 is connected between the front drain outlet 12 and the rear drain outlet 15 of the air-conditioning assembly 10, and a water pump 35 is arranged on the condensate water pipeline 45, a condensate water front check valve 32 is arranged on the condensate water pipeline 45 between the water pump 35 and the front drain outlet 12, and a condensate water rear check valve 37 is arranged on the condensate water pipeline 45 between the water pump 35 and the rear drain outlet 15; and the condensate water pipeline 45 is connected to the evaporator spray pipeline 33, the water pump 35 is located at the connecting position between the condensate water pipeline 45 and the evaporator spray pipeline 33, and a hot and cold semiconductor device 36 is arranged on the evaporator spray pipeline 33, and a plurality of evaporator sprays 34 are arranged at the end of the evaporator spray pipeline 33, the evaporator spray 34 faces the evaporator fan assembly 31, and the evaporator spray 34 is installed at the air outlet corresponding to the evaporator fan assembly 31. In this way, the drain outlets at the bottom of the air conditioning assembly 10 are connected by the condensed water pipeline 45, and a water pump 35 is arranged between the front and rear drain outlets. When the air humidity in the car is lower than the preset value, the water pump 35 starts to work, and the condensed water front check valve 32, the condensed water rear check valve 37 and the cold and hot semiconductor device 36 are opened. The condensed water generated by the air conditioning assembly 10 flows through the water pump 35 and the cold and hot semiconductor device 36 and is finally absorbed to the evaporator spray 34, so that it sprays mist water molecules into the car. When the temperature in the car is high, the cold and hot semiconductor device 36 can present a low temperature state, so that the water molecules sprayed by the atomizer are synchronously in a low temperature state, which can not only increase the air humidity in the car, but also assist in cooling the car. When the temperature in the car is low, the cold and hot semiconductor device 36 can present a high temperature state, so that the water molecules sprayed by the atomizer are synchronously in a high temperature state, which can not only increase the air humidity in the car, but also assist in heating the car. Achieve dual use of one thing, improve the working efficiency of the air conditioner, and create a good riding environment for users.

[0050] It should be noted that the condensed water pipeline 45 is also connected to a condensed water storage device 38 , and the condensed water storage device 38 is installed on the vehicle body 42 .

On the other hand, the passenger area can be humidified to improve the passenger comfort. It can also be connected in series with the water heating system to supply water to it. At the same time, the collected water can be stored in a water tank for subsequent use, thereby improving the utilization rate of water resources and achieving the purpose of energy saving. Its beneficial effects are:

[0053] 1. The utility model can collect rainwater and filter, disinfect and process it, so that it can be stored in the water tank, thereby improving the utilization rate of water resources and reducing the frequency of adding water to the water tank.
