Air conditioning device, air conditioning system and vehicle

Technical Field

The present application relates to the field of air conditioning, and more particularly, to an air conditioning apparatus, an air conditioning system, and a vehicle.

Background

At present, on an electric automobile, the dual-temperature-zone implementation mode of an air conditioning box of an air conditioning system is basically that air is mixed through a temperature air door, air from an air blower is cooled through an evaporator and then flows through the temperature air door, and by adjusting the opening of the temperature air door, a part of air flows through a high-voltage electric heater on the air side or a warm air core. At this time, since there is no engine waste heat, water in the warm air core needs to be heated by the high pressure water side heater in order to heat the flowing wind. And then, the opening degrees of the air doors at the left side and the right side are adjusted to be different, so that the mixed hot air quantity is regulated, and the independent regulation of the temperatures at the left side and the right side is realized. However, this implementation method requires additional power consumption, especially when temperature partition control is required in the cooling mode, the common partition temperature control is that cold air is mixed into hot air heated by a positive temperature coefficient (Positive Temperature Coefficient, PTC) heater, and because the PTC heater needs to work, both the air side high-voltage electric heater works and water heating in a warm air core needs to consume power, so that energy cannot be saved, the whole electric quantity is wasted, and the cruising mileage of the whole vehicle is affected.

Referring to fig. 1 to 4, an air conditioning system 100 according to an embodiment of the present application is suitable for being installed on a vehicle to adjust air flow temperatures in different areas of a cabin. The air conditioning system 100 includes an air conditioner 1 and a control module 2, wherein the air conditioner 1 includes a body 10, a blower 20, a heating module 30, and a cooling module 40.

In the present embodiment, the body 10 is provided with a plurality of air inlets, for example, a first air inlet 101 and a second air inlet 102, which are respectively connected to the air chamber 15.

Further, the body 10 is pivoted with the circulation damper 17 between the first air inlet 101 and the second air inlet 102. The circulation damper 17 is swingable between the first air intake port 101 and the second air intake port 102. When the circulation damper 17 closes the second air inlet 102, the first air inlet 101 is simultaneously opened, so that the air in the external environment enters the air chamber 15 through the first air inlet 102, and the external circulation of the air flow is formed. When the circulation damper 17 closes the first air inlet 101, the second air inlet 102 is opened, so that the air in the vehicle enters the air chamber 15 through the second air inlet 102, and an internal circulation of the air flow is formed.

In some embodiments, the cabin of the vehicle may be divided into a plurality of seating areas, typically four seating areas. In the present embodiment, the first seating area 211 and the second seating area 212 are taken as examples, but the present utility model is not limited thereto. For example: the first seating area 211 is a driving area, the second seating area 212 is a co-driving area, and the first air outlet 11 is communicated with the first seating area 211, and the second air outlet 12 is communicated with the second seating area 212.

In addition, the air conditioner 1 further includes a motor assembly 61, a link mechanism 62, a first damper 63, and a second damper 64, wherein the link mechanism 62 is connected to the motor assembly 61, the first damper 63, and the second damper 64, respectively. The first and second dampers 63 and 64 may be a single damper or a plurality of dampers, respectively, and the number thereof corresponds to the first and second air outlets 11 and 12.

The blower 20 may be, but is not limited to, a blower installed in the air chamber 15 to blow out in a direction toward the heat exchange chamber after sucking air from the first air inlet or the second air inlet, thereby driving the air inside the body 10 to flow. That is, after air is sucked into the fan from the first air inlet 101 or the second air inlet 102 (as indicated by the black solid arrow in fig. 1), an air flow flowing toward the heat exchange chamber 16 is generated by the driving of the fan 20, and the air flow is divided into a first air flow flowing into the first channel 161 and a second air flow flowing into the second channel 162 by the partition 18 during the flowing process (the one-way hollow arrow in fig. 1 indicates the flowing direction of the first air flow and the second air flow). In addition, in some embodiments of the present application, an air filter element 70 is further disposed between the two air inlets and the air chamber 15, so that the air of the first air inlet 101 or the second air inlet 102 can be filtered by the air filter element 70 before entering the air chamber 15, so as to maintain the air quality during the air outlet.

Please refer to fig. 1 and 2. The heating module 30 is disposed at a side of the heat exchange chamber adjacent to the first air outlet 11 and the second air outlet 12, and is used for performing a heating process on the air flowing toward the first air outlet 11 and the second air outlet 12. In some embodiments of the present application, the heating module 30 includes a module body 31, a first heating assembly 32, and a second heating assembly 33. The module body 31 is provided with a low-voltage connector 311, a high-voltage connector 312 and a control circuit 313, the low-voltage connector 311 is used for receiving signals of the whole vehicle, and the high-voltage connector 312 is used for being connected with the circuit of the vehicle. The first and second heat generating components 32 and 33 may be, but are not limited to, PTC heaters or other heat generating bodies that can emit heat to raise the temperature of the peripheral region. In the embodiment in which the first heat generating component 32 and the second heat generating component 33 are PTC heaters, each of the first heat generating component 32 and the second heat generating component 33 includes a plurality of PCT sheet components 301 and a plurality of heat dissipating fins 302 arranged in a staggered manner to dissipate heat to the ambient air to heat the ambient air.

In addition, the first heating element 32 and the second heating element 33 may be selectively disposed on the module body 31 side by side in parallel, and electrically connected to the control circuit 313, respectively, so as to perform the heating process under the control of the control circuit 313. When the heating module 30 is disposed in the heat exchange chamber 16, the first heating element 32 corresponds to the first channel 161 for heating the first air flow flowing in the first channel 161 toward the first air outlet 11, and the second heating element 33 corresponds to the second channel 162 for heating the second air flow flowing in the second channel 162 toward the second air outlet 12.

Please refer to fig. 1 and 3. The cooling module 40 is disposed in the heat exchange chamber 16 and between the fan 20 and the heating module 30, and is used for performing a cooling process on the air flowing toward the first air outlet 11 and the second air outlet 12. In some embodiments of the present application, the refrigeration module 40 includes a first heat sink assembly 41 and a second heat sink assembly 42, and a central partition 43 is disposed between the first heat sink assembly 41 and the second heat sink assembly 42. The first and second heat absorbing members 41 and 42 may be, but are not limited to, symmetrically disposed at opposite sides of the central partition 43 in the form of evaporators. When the cooling module 40 is disposed in the heat exchange chamber 16, the first heat absorbing component 41 corresponds to the first channel 161 for performing a cooling process on the first air flow flowing in the first channel 161 toward the first heat generating component 32, and the second heat absorbing component 42 corresponds to the second channel 162 for performing a cooling process on the second air flow flowing in the second channel 162 toward the second heat generating component 33.

In some embodiments of the present application, the first and second heat sink assemblies 41, 42 are connected to the same coolant outlet line, but are each connected to a different coolant inlet line, and are disposed in parallel in the heat exchange chamber 16. For example, in the present embodiment, the refrigeration module 40 further includes a first inlet line 44, a second inlet line 45, and an outlet line 46 (in fig. 1 and 3, the first inlet line 44 and the second inlet line 45 are indicated by solid lines, the outlet line 46 is indicated by broken lines) as coolant delivery lines, and front ends of the first inlet line 44 and the second inlet line 44 are connected to compressors for pressurizing the coolant, respectively. The first inlet line 44 is connected to the coolant inlet of the first heat absorption assembly 41, and a first electronic expansion valve 441 is provided between the first inlet line and the compressor; the second inlet pipeline 45 is connected to the coolant inlet of the second heat absorbing assembly 42, and a second electronic expansion valve 451 is arranged between the second inlet pipeline and the compressor; while the outlet line 46 is connected to the coolant outlets of both the first and second heat sink assemblies 41, 42.

The first electronic expansion valve 441 and the second electronic expansion valve 451 can respectively regulate the flow of the coolant entering the first inlet pipeline 44 and the second inlet pipeline 45, so that the coolant flows into the first heat absorption assembly 41 and the second heat absorption assembly 42, and after the coolant performs a refrigeration operation, the coolant flows out of the first heat absorption assembly 41 and the second heat absorption assembly 42 to the outlet pipeline 46 respectively, and in the process, the first air flow flowing into the first heat absorption assembly 41 in the first channel 161 and the second air flow flowing into the second heat absorption assembly 42 in the second channel 162 are cooled.

Illustratively, the first and second heat sink assemblies 41, 42 include the same or similar structures, e.g., both include opposite open and closed ends 401, 402. The first heat absorbing assembly 41 is provided with a plurality of first fluid guides 411 and a plurality of first heat dissipating assemblies 412 between the open end 401 and the closed end 402, and the second heat absorbing assembly 42 is provided with a plurality of second fluid guides 421 and a plurality of second heat dissipating assemblies 422 between the open end 401 and the closed end 402. The flow guiding pipes are flat pipes or other types of pipelines which are distributed in parallel in a plurality of rows, the heat dissipation components can be but are not limited to heat dissipation fins, and the flow guiding pipes of each heat absorption component and the heat dissipation components are arranged in a staggered manner.

The open end 401 of the first heat absorbing component 41 is further provided with a first shunt tube 413 and a first collecting pipe 414, and the closed end 402 is provided with a first collecting pipe 415. The first diversion pipe 413 is respectively connected to the first inlet pipe 44 and a part of the first diversion pipes 411, the first collecting pipe 414 is respectively connected to the outlet pipe 46 and another part of the first diversion pipes 411, and the first collecting pipe 415 is connected to the first diversion pipes 411 at the closed end 402. Similarly, the open end 401 of the second heat sink assembly 42 is further provided with a second shunt tube 423 and a second manifold 424, and the closed end 402 is provided with a second manifold 425. The second shunt tube 423 is respectively connected to the second inlet pipeline 45 and a part of the second diversion tubes 421, the second collecting tube 424 is respectively connected to the outlet pipeline 46 and another part of the second diversion tubes 421, and the second collecting tube 425 is connected to the plurality of second diversion tubes 421 at the closed end 402.

Therefore, the coolant enters the first diversion pipe 413 through the first inlet pipe 44 on the flow path of the first heat absorption assembly 41, flows to the first collecting pipe 425 through a part of the first diversion pipe 411, enters the first diversion pipe 413 through another part of the first diversion pipe 411, and finally flows out to the outlet pipe 46. It will be appreciated that since the first heat sink assembly 41 is of similar construction to the second heat sink assembly 42, the coolant is in the flow path of the second heat sink assembly 42 and is identical to the first heat sink assembly 41.

In some embodiments, the air conditioner 1 may further include a plurality of temperature sensing assemblies 50 disposed in the first channel 161 and the second channel 162, respectively, to sense the temperature of the first air flow in the first channel 161 and the temperature of the second air flow in the second channel 162. For example: in the first channel 161, the temperature sensing element 50 is disposed between the first heat generating element 32 and the first heat absorbing element 41, and between the first heat generating element 32 and the first air outlet 11, and the second channel 162 is also disposed at a corresponding position. Of course, the location of the temperature sensor assembly 50 is not limited thereto, and depends on the requirements.

Please refer to fig. 1 and fig. 4. The control module 2 is electrically connected to the blower 20, the heating module 30, and the cooling module 40, and is used for controlling the blower 20, the heating module 30, and the cooling module 40 to operate, and can enable the blower 20, the first heating component, the second heating component, the first heat absorbing component, the second heat absorbing component, and the like to be independently controlled, so as to adjust the flow rate and the flow velocity of the air flowing into the air chamber, and the temperature of the air flowing out to the first sitting area 211 and the second sitting area 212, thereby achieving the function of zone temperature control in the vehicle cabin. In more detail, the control module 2 can be used for storing and executing a plurality of operation modes such as a cooling mode, a heating mode, a dehumidifying and heating mode, etc., for the user to switch according to the current requirement.

The application scenario of each operation mode in the embodiment of the present application is further described below. In the cooling mode, the heating mode, or the dehumidifying and heating mode, the air is driven by the fan 20 to form an air flow entering from the first air inlet 101 or the second air inlet 102, and after being filtered by the air filter 70, flows from the air chamber 15 toward the heat exchange chamber 16, and is separated into a first air flow and a second air flow by the partition 18.

In the cooling mode, the control module 2 controls the first electronic expansion valve 441 and the second electronic expansion valve 451 to respectively regulate the flow of the coolant flowing into the first heat absorption assembly 41 and the second heat absorption assembly 42 according to the set temperatures of the first seating area 211 and the second seating area 212, and enables (enable) the first heat absorption assembly 41 and the second heat absorption assembly 42 to operate, so that the coolant absorbs heat in the first heat absorption assembly 41 and the second heat absorption assembly 42, and exchanges heat when the first air flow and the second air flow respectively flow through the first heat absorption assembly 41 and the second heat absorption assembly 42, thereby reducing the temperatures of the first air flow and the second air flow to achieve the cooling effect. Then, the air flows into the cabin through the first air outlet 11 and the second air outlet 12 respectively.

In more detail, the control module 2 can control the flow rate of the coolant by adjusting the opening of the first electronic expansion valve 441 and the second electronic expansion valve 451 respectively, and detect the temperature of the air passing through the first heat absorption assembly 41 and the second heat absorption assembly 42 together with the temperature sensors 50 disposed between the heat absorption assembly and the heat generation assembly, so as to precisely control the temperature of the first air flow and the second air flow. For example, the temperatures of the first air stream and the second air stream may be the same or different depending on the predetermined temperature set by the user. The control module 2 can correspondingly adjust the opening of the first electronic expansion valve 441 and/or the second electronic expansion valve 451 according to the set temperature and the detected temperature fed back by the temperature sensor 50, so as to respectively adjust the flow of the coolant, so that the first air flow and the second air flow can be cooled to a predetermined low temperature and supplied into the first sitting region 211 and the second sitting region 212, thereby achieving the purpose of controlling the temperature of the first sitting region 211 and the second sitting region 212 in a partitioning manner. It should be noted that, since the heating module 30 is not required to be driven to work during the cooling process, the energy-saving effect is better in the state that the control module 2 disables (disable) the heating module 30.

In the heating mode, the control module 2 enables the first heating element 32 and the second heating element 33 to operate according to the temperatures set by the first sitting area 211 and the second sitting area 212, and controls the power of the first heating element 32 and the second heating element 33, so that the first air flow and the second air flow can be heated and raised when passing through, and respectively flow into the cabin from the first air outlet 11 and the second air outlet 12. In more detail, the control module 2 can adjust the power of the first heating element 32 and the second heating element 33, and simultaneously match each temperature sensing element 50 disposed between the heating element and the air outlet to detect the temperature of the air passing through the first heating element 32 and the second heating element 33, and make an adaptive adjustment, so that the temperature of the first air flow flowing to the first seating area 211 and the second seating area 212 and the temperature of the second air flow can reach a predetermined high temperature, thereby achieving the goal of zonal temperature control. Since the cooling module 40 does not operate during heating, the control module 2 can also have a better energy-saving effect in a state where the cooling module 40 is disabled.

Regarding the dehumidification heating mode, the control module 2 controls the fan 20, the heating module 30 and the cooling module 40 to operate simultaneously when the passenger needs to heat and dehumidify. In the dehumidification, as in the operation of the cooling mode, the control module 2 controls the first electronic expansion valve 441 and the second electronic expansion valve 451 to respectively regulate the flow rate of the coolant flowing into the first heat absorption assembly 41 and the second heat absorption assembly 42, so that the coolant absorbs heat in the first heat absorption assembly 41 and the second heat absorption assembly 42, and when the first air flow and the second air flow pass through the first heat absorption assembly 41 and the second heat absorption assembly 42, respectively, heat exchange is performed, and water vapor in the air condenses into water droplets on the surfaces of the first heat absorption assembly 41 and the second heat absorption assembly 42 and is discharged outside the vehicle, thereby playing the dehumidification effect. In the heating aspect, since the temperature of the air passing through the heat absorbing assembly is reduced, the control module 2 controls the power of the first and second heat generating assemblies 32 and 33 according to the temperatures sensed by the temperature sensing assemblies 50 disposed between the heat absorbing assembly and the heat generating assembly and the temperature sensing assemblies 50 disposed between the heat generating assembly and the air outlet, so as to adjust the air outlet temperatures of the first and second air flows to the first and second air outlets 11 and 12, respectively, thereby achieving the effect of controlling the temperatures of the first and second seating areas 211 and 212. Therefore, the double effects of heating and dehumidifying the riding area can be achieved through the refrigerating process of the heat absorbing component and the heating process of the heating component.

In addition, the motor assembly 61 drives the connecting rod assembly 62 to drive the opening and closing and opening degrees of the air doors according to the operation modes and the air volume regulated by the riding area, so as to control the opening and closing of the air outlets to regulate the air volume.

It should be noted that, in the dehumidifying and heating mode, since the purpose of the heat absorbing assembly for cooling is to condense the water vapor into water droplets instead of lowering the water vapor to a predetermined low temperature, the amount of coolant required is relatively small. Therefore, the control module 2 can control the compressor to maintain a lower rotation speed, and simultaneously reduce the opening of the first electronic expansion valve 441 and the second electronic expansion valve 451 to reduce the flow rate of the coolant, so that the temperature of the air flowing through the heat absorption assembly is not reduced too low, and the power of the heat generation assembly in the heating process is naturally not required to be too high, thereby achieving the effect of reducing the energy consumption.

As can be seen from the above description, according to the embodiment of the present application, through the structural design of the first channel and the second channel, the configuration of the refrigeration module having the first heat absorption component and the second heat absorption component connected in parallel and the configuration of the heating module having the dual heating components can be respectively adjusted to the temperatures of different areas in the vehicle cabin, so that the problem of extra electric energy consumption caused by mixing in hot air volume when the current air conditioning system is in the temperature adjustment mode of zone temperature control is solved, and the rotation speed of the compressor and the power of the heating components can be reduced in the dehumidification heating mode, thereby further achieving the energy saving effect. Especially for pure electric vehicles, the energy consumption can be reduced, the energy is saved effectively, and a good lifting effect can be achieved on the continuous running force.

The foregoing is merely exemplary of the present application and is not intended to limit the present application. Various modifications and changes may be made to the present application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc. which are within the spirit and principles of the present application are intended to be included within the scope of the claims of the present application.
