The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art according to the specific circumstances.
A vehicle air conditioning apparatus 100 according to an embodiment of the present invention is described in detail below with reference to fig. 1 and 2, wherein the vehicle air conditioning apparatus 100 is applied to a vehicle to heat a battery of the vehicle, and in particular, a heat exchanging flow path is provided on the battery. Alternatively, the vehicle may be an electric vehicle.
As shown in fig. 1 to 2, the vehicle air conditioning apparatus 100 according to the embodiment of the present invention includes an air conditioning duct 1 blowing toward the inside of the vehicle, the air conditioning duct 1 having an air inlet a and an air outlet B, it being understood that external air enters the air conditioning duct 1 through the air inlet a, and air having undergone heat exchange in the air conditioning duct 1 is blown into the inside of the vehicle from the air outlet B to condition the space in the vehicle.
The vehicle air conditioning apparatus 100 according to the embodiment of the invention further includes: a compressor 2, a gas intercooler 3, a battery heating heat exchanger 4, a bypass water valve 16, an outdoor heat exchanger 5, a first bypass valve 6, a first throttling element 7, an indoor heat exchanger 8 and a second bypass valve 12, wherein the compressor 2 has a discharge port C and a return port D. It will be appreciated that the specific construction and operation of the compressor 2 is well known in the art and will not be described in detail herein.
The air internal cooler 3 is arranged in the air conditioning duct 1, the air conditioning duct 1 is internally provided with an air door 14, the air door 14 is movable between an avoidance position and a blocking position for blocking air from flowing to the air internal cooler 3, and it is to be noted that when the air door 14 moves to the avoidance position, air entering the air conditioning duct 1 from the air inlet A flows through the air internal cooler 3 to exchange heat with the air internal cooler 3. When the damper 14 is moved to the blocking position, the damper 14 blocks air flow to the gas intercooler 3, and no air or only a small amount of air flows through the gas intercooler 3.
The inlet of the gas intercooler 3 is connected to the exhaust port C. The battery heating heat exchanger 4 comprises a water flow path 41 and a refrigerant loop 42 which mutually exchange heat, the refrigerant loop 42 is connected with the outlet of the gas internal cooler 3, and two ends of the water flow path 41 are suitable for being connected with a heat exchange flow path on a battery to form a water loop. The bypass water valve 16 is used to control the water circuit on and off. Specifically, when the battery needs to be heated, the bypass water valve 16 is controlled so that the water circuit is connected, and the water flow in the water flow path 41 after heat exchange with the refrigerant circuit 42 flows through the heat exchange flow path on the battery to heat the battery. When the bypass water valve 16 is controlled such that the water circuit is shut off, the water flow cannot form a circulation flow in the water circuit, thereby stopping the heating process of the battery.
Preferably, both ends of the bypass water valve 16 are connected to both ends of the water flow path 41, respectively, and when the bypass water valve 16 is opened, the water flow path 41 is bypassed, and the water flow does not flow through the water flow path 41, and the water circuit is shut off. When the bypass valve 16 is closed, water flows through the water flow path 41 and the water circuits communicate.
The outdoor heat exchanger 5 is connected to the refrigerant circuit 42. The first bypass valve 6 and the first throttle element 7 are connected in parallel, and the first bypass valve 6 is connected in series between the outdoor heat exchanger 5 and the refrigerant circuit 42, that is, the first throttle element 7 is also connected in series between the outdoor heat exchanger 5 and the refrigerant circuit 42, and the refrigerant flowing out of the refrigerant circuit 42 can be switched to flow to the first bypass valve 6 or the first throttle element 7. Specifically, the first throttling element 7 plays a role of throttling and reducing pressure. Alternatively, the first throttling element 7 is a solenoid expansion valve. Alternatively, the first bypass valve 6 may be a solenoid valve.
The indoor heat exchanger 8 is arranged in the air conditioning duct 1, a first end of the indoor heat exchanger 8 is connected with the outdoor heat exchanger 5 through a first refrigerant flow path 9, a second end of the indoor heat exchanger 8 is connected with the air return port D through a second refrigerant flow path 10, and a second throttling element 11 is connected in series on the first refrigerant flow path 9. Specifically, the second throttling element 11 plays a role in throttling and reducing pressure. Alternatively, the second throttling element 11 is a solenoid expansion valve.
A first end of the second bypass valve 12 is connected to the first refrigerant flow path 9 and a first end of the second bypass valve 12 is connected between the outdoor heat exchanger 5 and the second throttling element 11, and a second end of the second bypass valve 12 is connected to the second refrigerant flow path 10. Alternatively, the second bypass valve 12 may be a solenoid valve.
Specifically, when the vehicle air conditioner 100 is in the heating mode: the first bypass valve 6 is closed, the second bypass valve 12 is opened, the air door 14 moves to the avoiding position, the air conditioner refrigerant is compressed into a high-temperature high-pressure state by the compressor 2 and then enters the gas internal cooler 3, at the moment, the gas internal cooler 3 is provided with air to flow through and heat the air, and the air in the air conditioner air duct 1 is heated by the gas internal cooler 3 and then enters the interior of the vehicle from the air outlet B so as to achieve the purpose of heating.
The refrigerant in the gas internal cooler 3 is initially cooled and then enters the refrigerant loop 42 of the battery heating heat exchanger 4. If the battery needs to be heated at this time, the bypass water valve 16 is controlled to circulate the water loop, and the water flow in the water flow path 41 obtains heat in the refrigerant loop 42 to heat the battery and further cool the refrigerant. Because the first bypass valve 6 is closed, the refrigerant flows out of the battery heating heat exchanger 4, throttled by the first throttling element 7, becomes low-temperature low-pressure and enters the outdoor heat exchanger 5 for evaporation, and then enters the second refrigerant flow path 10 through the first refrigerant flow path 9 and the second bypass valve 12 and returns to the compressor 2.
When the vehicle air conditioning apparatus 100 is in the cooling mode: at this time, the first bypass valve 6 is set to be opened, the second bypass valve 12 is closed, the air door 14 moves to the blocking position, the air-conditioning refrigerant is compressed into a high-temperature high-pressure state by the compressor 2 and then enters the gas internal cooler 3, and at this time, the high-temperature refrigerant in the gas internal cooler 3 subsequently enters the refrigerant loop 42 of the battery heating heat exchanger 4 because the gas internal cooler 3 does not have air flowing through and does not exchange heat. If the battery needs to be heated at this time, the bypass water valve 16 is controlled to circulate the water loop, and the water flow in the water flow path 41 obtains heat in the refrigerant loop 42 to heat the battery and further cool the refrigerant. Because the first bypass valve 6 is opened, the refrigerant flows out of the battery heating heat exchanger 4 and then directly enters the outdoor heat exchanger 5 through the first bypass valve 6 to exchange heat, and at the moment, the outdoor heat exchanger 5 is used as an air cooler or a condenser. The refrigerant discharged from the outdoor heat exchanger 5 is throttled and depressurized by the second throttling element 11 on the first refrigerant flow path 9 to become low-temperature low-pressure refrigerant, and then the low-temperature low-pressure refrigerant enters the indoor heat exchanger 8 to be subjected to evaporation refrigeration, and the air in the air conditioner air duct 1 is cooled by the indoor heat exchanger 8 and then enters the interior of the vehicle from the air outlet B so as to realize the purpose of refrigeration. The refrigerant flows out of the indoor heat exchanger 8, enters the second refrigerant passage 10, and flows back to the compressor 2.
When the vehicle air conditioning apparatus 100 is in the dehumidification mode: at this time, the first bypass valve 6 and the second bypass valve 12 may be both set to be closed, the damper 14 moves to the avoiding position, at this time, the air in the air conditioning duct 1 exchanges heat with the indoor heat exchanger 8 and the gas internal cooler 3 at the same time, and the first throttling element 7 and the second throttling element 11 are adjusted to be in a proper state, so that the temperatures of the indoor heat exchanger 8 and the gas internal cooler 3 are in a mode suitable for dehumidification. If the battery needs to be heated at this time, the bypass water valve 16 is controlled to circulate the water circuit, and the water flow in the water flow path 41 obtains heat in the refrigerant circuit 42 to heat the battery.
According to the vehicle air conditioning equipment 100 provided by the embodiment of the invention, the battery heating heat exchanger 4 and the bypass water valve 16 are arranged, so that the water flow absorbing the heat of the refrigerant in the refrigerant loop 42 can be selectively utilized to heat the battery, the energy consumption is saved, and the influence of the heating process on the endurance mileage of the battery can be reduced.
In the embodiment of the present invention, the indoor heat exchanger 8 is located at the upstream of the gas internal cooler 3, the air conditioning duct 1 is provided with a partition plate to define two sub-channels, the indoor heat exchanger 8 is located at the upstream of the two sub-channels, the gas internal cooler 3 is provided in one of the sub-channels, each sub-channel has an air outlet B, and the air door 14 controls one of the sub-channels to communicate with the air inlet a. So that it is ensured that in the cooling mode no air flows through the gas intercooler 3 without heat exchange. Specifically, a fan 15 is disposed in the air-conditioning duct 1, and the fan 15 rotates to introduce external air into the air-conditioning duct 1 through the air inlet a. In some specific examples of the invention, the fan 15 is located upstream of the indoor heat exchanger 8. Optionally, the air inlets A are multiple.
In the embodiment of the present invention, the damper 14 is rotatably provided in the air conditioning duct 1, so that the moving mode of the damper 14 is simple.
As shown in fig. 1 and 2, in some embodiments of the present invention, the vehicle air conditioning apparatus 100 further includes a regenerator 13, the regenerator 13 including a high temperature flow path and a low temperature flow path that are independent and exchange heat with each other, the high temperature flow path forming a portion of the first refrigerant flow path 9 between the outdoor heat exchanger 5 and the second throttling element 11, the low temperature flow path forming a portion of the second refrigerant flow path 10, and a second end of the second bypass valve 12 connected between the low temperature flow path and the indoor heat exchanger 8. That is, the high temperature flow path and the low temperature flow path are two independent refrigerant flow paths, the refrigerant in the high temperature flow path can exchange heat with the refrigerant in the low temperature flow path, the high temperature flow path is a part of the first refrigerant flow path 9, and the high temperature flow path is located between the outdoor heat exchanger 5 and the second throttling element 11. In the example shown in fig. 1, the first end of the second bypass valve 12 is connected between the high temperature flow path and the second throttling element 11. In the example shown in fig. 2, the first end of the second bypass valve 12 is connected between the high-temperature flow path and the outdoor heat exchanger 5.
In the description of the present invention, "high temperature" and "low temperature" in the high temperature flow path and the low temperature flow path are not particularly limited to specific temperatures, but are merely for indicating that the temperature of the refrigerant flowing into the high temperature flow path may be higher than the temperature of the refrigerant flowing into the low temperature flow path.
Specifically, when the vehicle air conditioner 100 is in the heating mode, the refrigerant flowing out of the outdoor heat exchanger 5 flows into the high-temperature flow path of the regenerator 13, the refrigerant flowing out of the high-temperature flow path flows into the low-temperature flow path through the second bypass valve 12, and the refrigerant flowing out of the low-temperature flow path returns to the compressor 2. Since the temperature difference between the refrigerant in the high temperature flow path and the refrigerant in the low temperature flow path is close to 0 in the heating mode, the regenerator 13 has no regenerative action.
When the vehicle air conditioning apparatus 100 is in the cooling mode, the refrigerant flowing out of the outdoor heat exchanger 5 flows into the high-temperature flow path of the regenerator 13, the refrigerant flowing out of the high-temperature flow path is throttled and depressurized by the second throttling element 11, and then discharged into the indoor heat exchanger 8 to exchange heat, the refrigerant flowing out of the indoor heat exchanger 8 flows into the low-temperature flow path, and the refrigerant flowing out of the low-temperature flow path returns to the compressor 2. Since the temperature of the refrigerant flowing into the high-temperature flow path is higher than the temperature of the refrigerant flowing into the low-temperature flow path, the regenerator 13 has a regenerative effect, and thus the heating effect of the vehicle air conditioning apparatus 100 can be improved.
In some embodiments of the present invention, as shown in fig. 1 and 2, the regenerator 13 includes a housing 130, a refrigerant pipe 131, an injection pipe 132, and a discharge pipe 133, the refrigerant pipe 131 is disposed in the housing 130 and both ends of the refrigerant pipe 131 are connected to the outdoor heat exchanger 5 and the second throttling element 11 to define a high temperature flow path, the injection pipe 132 and the discharge pipe 133 define a low temperature flow path, one end of the injection pipe 132 is opened and the other end of the injection pipe 132 is connected to the indoor heat exchanger 8, an inlet of the discharge pipe 133 is positioned at an upper portion of the housing 130 and an outlet of the discharge pipe 133 is connected to the return air port D. Specifically, the refrigerant discharged from the injection pipe 132 into the housing 130 is subjected to gas-liquid separation in the housing 130, and the separated gaseous refrigerant is discharged back into the compressor 2 through the discharge pipe 133, so that the liquid content of the refrigerant discharged back into the compressor 2 can be reduced, and the phenomenon of liquid impact of the compressor 2 is avoided.
