Description

Technical Field

[0001] The utility model relates to the field of vehicle air - conditioning systems, and particularly to a vehicle high - efficiency energy - saving air - conditioning system. Background Art

[0002] With the improvement of living standards, cars have become ordinary means of transportation for many families. While enjoying the convenient life brought by cars, people's requirements for the riding comfort of cars are also increasing day by day. At the same time, with the popularization of new - energy vehicles and electric vehicles, people's attention to the vehicle's cruising range and the energy - consumption efficiency of vehicle air - conditioners is also increasing day by day.

[0003] However, in a closed carriage exposed to high temperature and high light for a long time in summer, the air temperature can rise to 75 - 80°C, and the interior temperature can even reach 120 - 125°C. The vehicle air - conditioning system needs to consume a large amount of energy to lower the interior temperature. During the refrigeration process, a large amount of energy is spent on the latent - heat dehumidification process of the air and is discharged from the vehicle along with the condensed water; at the same time, the overly dry air outlet after dehumidification also greatly affects the riding comfort in summer. The long - term inefficient dehumidification and refrigeration also consume a large amount of energy, reducing the effective driving range of new - energy vehicles. Especially for pure - electric vehicles, in summer conditions, after using the air - conditioning system, the effective driving range will be reduced by 15% - 20%.

[0004] Therefore, it is very necessary to provide a high - efficiency energy - saving air - conditioning system that can make full use of limited energy for rapid cooling and provide comfort for vehicle occupants. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a vehicle high - efficiency energy - saving air - conditioning system, which is used to solve the problems in the prior art that the energy - consumption utilization rate of the vehicle air - conditioning system is low during the refrigeration process, and it cannot provide sufficient air - humidity control during refrigeration, resulting in low body - feeling comfort for vehicle occupants. The utility model utilizes the low - temperature condensed water generated by the vehicle air - conditioning system itself during refrigeration, atomizes it, and makes full use of its latent heat to achieve rapid cooling of the passenger compartment, while providing better human comfort, efficiently utilizing the refrigerating capacity of the air - conditioning system, avoiding a large amount of energy lost through the discharge of condensed water in the traditional air - conditioning system, and realizing a high - efficiency energy - saving air - conditioning system.

Detailed Embodiments

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figure 1 and Figure 2 In an embodiment of the present invention, a vehicle-mounted high-efficiency energy-saving air-conditioning system includes a parameter acquisition module 21, an air-conditioning system control module 22, an air-conditioning box 1, a compressor, an electronic control pilot valve 17, an ultrasonic atomizer 18, and a plurality of air inlets and air outlets provided on the air-conditioning box 1. Corresponding air doors are installed at each air inlet and air outlet. Specifically, the air inlets include an external circulation air inlet 2 and an internal circulation air inlet 3. The external circulation air inlet 2 is communicated with the external space of the vehicle, and the internal circulation air inlet 3 is communicated with the internal space of the carriage. An internal and external circulation air door 4 is installed at the corresponding positions of the external circulation air inlet 2 and the internal circulation air inlet 3 in the air-conditioning box 1. The air outlets include a defrosting air outlet 6, a face-blowing air outlet 8, and a foot-blowing air outlet 10. A defrosting air door 7 is installed at the corresponding position of the defrosting air outlet 6 in the air-conditioning box 1. A face-blowing air door 9 is installed at the corresponding position of the face-blowing air outlet 8 in the air-conditioning box 1. A foot-blowing air door 11 is installed at the corresponding position of the foot-blowing air outlet 10 in the air-conditioning box 1. Among them:

[0032] The parameter acquisition module 21 is used to acquire the environmental parameters of the vehicle. The environmental parameters are vehicle internal and external environmental parameters that at least include vehicle interior temperature information, vehicle interior air humidity information, vehicle exterior temperature information, and vehicle exterior sunlight illumination information.

[0033] Specifically, the parameter acquisition module 21 obtains the environmental parameters through various sensors provided on the vehicle body. The sensors can specifically adopt temperature sensors, humidity sensors, temperature and humidity sensors, and / or light sensors. The temperature sensor is used to acquire vehicle interior temperature information and vehicle exterior temperature information. The humidity sensor is used to acquire vehicle interior humidity information. The light collector is used to acquire vehicle exterior sunlight illumination intensity information. The types of sensors are not limited to those listed in this embodiment. Any sensor that can acquire vehicle interior and exterior environmental information parameters can be used;

[0034] The air-conditioning system control module 22 is used to determine whether the acquired data meets the preset atomization humidification and rapid refrigeration conditions. If so, it generates an instruction to make the air-conditioning system perform atomization humidification refrigeration. If not, it generates an instruction to make the air-conditioning system stop atomization humidification refrigeration.

[0035] The conditions for implementing atomizing humidification and rapid refrigeration may specifically be that the outside temperature is higher than the first temperature threshold, the inside temperature is higher than the second temperature threshold, the difference between the actual inside temperature value and the target inside temperature value is higher than the third temperature threshold, the outside sunlight intensity is higher than the sunlight threshold, the inside humidity value is lower than the first humidity threshold, and the inside fogging risk value is lower than the first fogging risk threshold. For example, when the outside temperature is higher than 30°C, the inside temperature is higher than 26°C, the difference between the actual inside temperature value and the target inside temperature value is higher than 3°C, the outside sunlight intensity is higher than 700 watts per square meter, and the inside humidity is lower than 70%, and the inside fogging risk value is lower than 20%, it is used as the condition for determining that the vehicle needs to perform atomizing humidification and rapid refrigeration. Of course, the conditions for atomizing humidification and rapid refrigeration are not limited to this method, and can be set accordingly according to actual situations such as different vehicle models or vehicle configuration types.

[0036] The conditions for stopping atomizing humidification and rapid refrigeration may specifically be that the outside temperature is lower than the fourth temperature threshold, the inside temperature is lower than the fifth temperature threshold, the difference between the actual inside temperature value and the target inside temperature value is lower than the sixth temperature threshold, the inside humidity value is higher than the second humidity threshold, and the inside fogging risk value is higher than the second fogging risk threshold. For example, when the outside temperature is lower than 20°C, the inside temperature is lower than 22°C, the difference between the actual inside temperature value and the target inside temperature value is lower than 0°C, and the inside humidity is higher than 85%, and the inside fogging risk value is higher than 60%, it is used as the condition for determining that the vehicle needs to stop atomizing humidification and rapid refrigeration. Of course, the conditions for stopping atomizing humidification and rapid refrigeration are not limited to this method, and can be set accordingly according to actual situations such as different vehicle models or vehicle configuration types.

[0037] The air-conditioning box 1, compressor, electronic control directional valve 17, ultrasonic atomizer 18, and air damper are used to respond to the instructions issued by the air-conditioning system control module 22;

[0038] Specifically, when the atomizing humidification and rapid refrigeration mode is turned on, the air-conditioning box 1 adjusts the air outlet mode to the face-blowing mode; the blower 5 is turned on to an appropriate gear (which can be a manually set gear or an automatically calculated air volume gear); the compressor is turned on to work to provide a cold source for the air-conditioning system, thereby reducing the temperature of the evaporator core 12; the electronic control directional valve 17 blocks the water inlet of the drain pipe 16 and guides the condensed water generated when the evaporator core 12 works to the condensate tank 15; the ultrasonic atomizer 18 starts to work after the water level in the condensate tank 15 exceeds the lowest water level to atomize the condensed water; the atomized condensed water will be sent to the passenger compartment along with the air outlet of the air-conditioning box 1.

[0039] The air-conditioning system control module 22 can be an existing controller on the vehicle, or a control module integrated with the vehicle control panel, or a separate control module separated from the vehicle control panel, and these do not affect the implementation of the present invention.

[0040] Data transmission is carried out between the parameter acquisition module 21 and the air-conditioning system control module 22 through a serial communication bus (such as CAN, LIN, SPI, etc., and these do not affect the implementation of the present invention).

[0041] The air-conditioning box body 1, the compressor, the electronic control guide valve 17, the ultrasonic atomizer 18, and each air door are used to respond to the instructions issued by the air-conditioning system control module 22;

[0042] The blower 5 in the air-conditioning box body 1 is electrically connected to the air-conditioning system control module 22. Specifically, a blower with linear speed control or pulse width modulation control can be used. The air-conditioning system control module 22 can linearly control the current working state of the blower 5 through current, voltage or pulse width signals. It should be noted that the control method for the blower 5 is not limited to these two methods of linear speed control or pulse width modulation.

[0043] The compressor is electrically connected to the air-conditioning system control module 22. The compressor responds to the instructions issued by the ventilation control module 23 and can be turned on and off (for a traditional mechanical compressor) or the corresponding power / speed can be turned on (for an externally controlled variable displacement compressor or an electric compressor).

[0044] The ultrasonic atomizer 18 is electrically connected to the air-conditioning system control module 22. The ultrasonic atomizer 18 adopts an atomizer with adjustable power (implemented through methods such as CAN, LIN, PWM, etc. It should be noted that the control method for the ultrasonic atomizer 18 is not limited to the above methods), and responds to the instructions issued by the air-conditioning system control module 22 to atomize the condensed water according to the instruction power.

[0045] In an embodiment of the present utility model: The ultrasonic atomizer 18 is installed in the condensate tank 15. The air outlet duct in the air-conditioning box body 1 adopts a double-layer design. One layer of the duct is connected to the internal air supply area of the air-conditioning box body 1, and one layer is connected to the internal atomization area of the air-conditioning box body 1. The Bernoulli principle during air flow is used to generate a negative pressure area at the air outlet to send the atomized air to the passenger compartment;

[0046] In an embodiment of the present utility model: The ultrasonic atomizer 18 is installed in the condensate tank 15. The condensate tank 15 is arranged below the internal air supply area of the air-conditioning box body 1, and directly atomizes the condensed water into the air supply area, and then sends it to the passenger compartment through the corresponding air outlet;

[0047] In an embodiment of the present utility model: The ultrasonic atomizer 18 is located inside the face-blowing air outlet 8, and a water guiding core 19 is arranged in the air-conditioning box body 1. One end of the water guiding core 19 is located in the condensate tank 15, and the other end of the water guiding core 19 is located at the ultrasonic atomizer 18. The ultrasonic atomizer 18 atomizes the condensed water drained through the water guiding core 19 and sends it to the passenger compartment through the air supply of the air conditioner;

[0048] The system further includes a remote control instruction receiving module 23 for receiving remote control instructions input by a remote terminal to control the turning on or off of the vehicle high-efficiency energy-saving air-conditioning system. The remote control instruction receiving module 23 is electrically connected to the air-conditioning system control module 22. Users can turn on or off the system through personalized settings or remotely control it through an Internet APP application.

[0049] Specifically, the air-conditioning system control module 22 can calculate the cooling demand inside the vehicle based on the environmental parameters inside and outside the vehicle detected by the parameter acquisition module 21 to determine whether the vehicle needs rapid cooling. When the cooling demand inside the vehicle is higher than the calibrated threshold, the air-conditioning system execution module 20 is activated to turn on the air conditioner. At the same time, the electronic control guide valve 17 is operated to guide the condensed water generated on the evaporator core 12 into the condensate tank 15, and the low-temperature water vapor is transported to the passenger compartment by controlling the opening degrees of each air door, realizing rapid cooling of the passenger compartment and improving the physical sensation comfort of the passengers and drivers in a high-temperature environment.

[0050] The air-conditioning system control module 22 can calculate the relative humidity of the air inside the vehicle based on the parameters inside and outside the vehicle detected by the parameter acquisition module 21 to determine whether the vehicle needs to turn on the humidification mode to improve the physical sensation comfort of the passengers and drivers. When the relative humidity of the air inside the vehicle is lower than the calibrated threshold, the electronic control guide valve 17 is controlled to guide all or part of the evaporator condensed water to the condensate tank 15, so as to atomize the condensed water by using the ultrasonic atomizer 18, and the low-temperature water vapor is transported to the passenger compartment by controlling the opening degrees of each air door, realizing rapid cooling of the passenger compartment and improving the physical sensation comfort of the passengers and drivers in a high-temperature environment.

[0051] The air-conditioning system control module 22 can detect the humidity level inside the vehicle according to the parameter acquisition module 21. When the humidity level inside the vehicle is higher than the calibrated threshold, the ultrasonic atomizer 18 is turned off, and at the same time, the electronic control guide valve 17 is controlled to open the water inlet of the drain pipe 16, so as to drain the condensed water out of the vehicle to reduce the humidity inside the vehicle and improve the driving comfort.

[0052] The air-conditioning system control module 22 can calculate the risk value of the front window of the vehicle from fogging based on the parameters inside and outside the vehicle detected by the parameter acquisition module 21 to determine whether the vehicle has a risk of the front window fogging. When the risk value of the front window of the vehicle from fogging is higher than the calibrated threshold, the ultrasonic atomizer 18 is turned off, and at the same time, the electronic control guide valve 17 is controlled to open the water inlet of the drain pipe 16, so as to drain the condensed water out of the vehicle to reduce the humidity inside the vehicle and at the same time reduce the risk of the front window of the vehicle from fogging, ensuring the driving safety of the vehicle.

[0053] An efficient and energy-saving vehicle air conditioning system provided by an embodiment of the present invention can automatically identify the vehicle's internal and external environmental parameters by monitoring the actual internal and external environment of the vehicle in real time. According to needs or remote control, it can automatically perform atomizing humidification and rapid refrigeration operations on the vehicle, so that the internal temperature of the vehicle can quickly drop and other environmental parameters can always be maintained within an appropriate range, quickly and effectively reducing the temperature inside the vehicle, maintaining a comfortable and safe humidity inside the vehicle, optimizing human comfort, preventing fogging, and ensuring vehicle driving safety. It makes full use of the air conditioning refrigeration capacity and reduces the additional energy consumption caused by condensate drainage. While effectively improving the comfort and safety of vehicle driving in summer, it can also reduce the refrigeration energy consumption of the vehicle, achieve the goal of vehicle energy conservation and emission reduction (for fuel vehicles), and extend the actual driving range (for new energy vehicles).
