And an independent second interior heat exchanger 110 is installed in the second sub-passage, and the second interior heat exchanger 110 always handles a cooling state, so that the air flowing through the second interior heat exchanger 110 can be cooled and dried.

And the second sub-channel blows air to the front windshield of the automobile through the defogging air outlet 205, and the air is processed by the second interior heat exchanger 110 to form dry air to blow to the front windshield for rapid defogging. In the defogging process, the first indoor heat exchanger 111 can always keep the refrigeration or heating state, so that the excessive temperature reduction in the defogging vehicle is reduced during heating.

The type of the automobile is different, and the automobile is divided into a fuel automobile and an electric automobile, wherein a refrigeration loop and an engine cooling liquid circulating system are configured in the fuel automobile; in contrast, in the case of an electric vehicle, only a refrigeration circuit is provided, and an engine coolant circulation system is not required. The following description is directed to different vehicle types.

The specific structural configuration for the electric vehicle is as follows.

As shown in fig. 2, after the vehicular air blowing device provided by the present invention is installed in an electric vehicle, the first interior heat exchanger 111 and the second interior heat exchanger 110 are connected to the components in the vehicle, such as the compressor 104, to form a refrigeration circuit.

Specifically, the compressor 104, the exterior heat exchanger 101, the first interior heat exchanger 111, the second interior heat exchanger 110, the throttle device, and the four-way valve 103 are connected together to form a refrigeration circuit. The four-way valve 103 is configured with an H port, an I port, a J port and a K port, wherein the H port is selectively communicated with the I port and the K port, the J port is selectively communicated with the I port and the K port, an exhaust port of the compressor 104 is connected with the H port, the exterior heat exchanger 101 is connected with the I port, the second interior heat exchanger 110 is connected with the J port, the first interior heat exchanger 111 is connected with the K port, the throttling device is connected between the exterior heat exchanger 101 and the first interior heat exchanger 111, and the second interior heat exchanger 110 is connected with an air suction port of the compressor 104 through the gas-liquid separator 109.

Specifically, the heat pump air conditioning system for a vehicle according to the present embodiment is mounted on a vehicle, wherein the air supply module is provided on the vehicle and supplies air to the inside of the vehicle, the compressor 104, the exterior heat exchanger 101, and other components are provided on the vehicle and located outside the vehicle, and the exterior heat exchanger 101 is provided with the exterior fan 102 for heat exchange.

The vehicle heat pump air-conditioning system can meet the requirements of conventional automobile refrigeration and heating, and specifically comprises the following steps: when the automobile executes a cooling mode, the four-way valve 103 switches the exhaust port of the compressor 104 to be connected with the external heat exchanger 101, so that the first internal heat exchanger 111 serves as an evaporator, under the action of the internal fan 203, air enters the first sub-channel and exchanges heat with the first internal heat exchanger 111 to form cold air, and the cold air is output into the automobile through the air-conditioning air outlet 206 to cool the environment in the automobile.

When the automobile executes a heating mode, the four-way valve 103 switches the exhaust port of the compressor 104 to be connected with the first in-vehicle heat exchanger 111, so that the first in-vehicle heat exchanger 111 is used as a condenser, under the action of the in-vehicle fan 203, air enters the first sub-channel and exchanges heat with the first in-vehicle heat exchanger 111 to form hot air, and the hot air is output to the interior of the automobile through the air-conditioning outlet 206 to heat the environment in the automobile.

When the fog occurs to the glass in the automobile and the defogging operation is required, the refrigerant flowing into the second interior heat exchanger 110 is a low-temperature refrigerant under the switching action of the four-way valve 103 no matter the interior is in the cooling or heating mode. Thus, when the demisting operation is performed, the wet air enters the second sub-channel and is condensed into water to be discharged after the heat exchange with the second in-vehicle heat exchanger 110, and dry cold air is formed and is output from the demisting air outlet, so that the demisting treatment is performed on the automobile glass mist.

Since the second interior heat exchanger 110 is connected between the four-way valve 102 and the suction port of the compressor 104, the second interior heat exchanger 110 always flows in the low-temperature refrigerant when the cooling and heating modes are switched. In the actual use process of a user, especially in a winter environment, the interior of the vehicle needs to convey hot air for heating treatment, so that the first interior heat exchanger 111 is used as a condenser to heat air. And the second in-vehicle heat exchanger 110 is independently disposed in the second sub-passage and is capable of dehumidifying humid air to meet the defogging requirement. Therefore, when heating, the second in-vehicle heat exchanger 110 can be used for condensing water vapor in the humid air for demisting, and compared with the prior art that demisting in the vehicle needs to be converted into a refrigeration mode, the fluctuation range of the temperature in the vehicle can be effectively reduced, so that the user experience is improved; meanwhile, because the heating mode can be kept, the first in-vehicle heat exchanger 111 is always in a heating state in the defogging process, more heat loss caused by cold-hot switching of the first in-vehicle heat exchanger 111 is avoided, and energy consumption is effectively reduced. In addition, when defogging is carried out in the heating mode, the refrigerant in the second in-vehicle heat exchanger absorbs heat in the vehicle, the heat is sent to the first in-vehicle heat exchanger after being compressed by the compressor, and then the heat is sent to the vehicle again by the in-vehicle air supply system, so that the heat recovery function is realized, on one hand, the requirement of defogging of glass in the vehicle can be met, on the other hand, the reduction of the maximum degree is excessive because of the temperature reduction in the vehicle during defogging, the temperature fluctuation range in the vehicle is reduced, the improvement of user experience is more facilitated, and the reduction of the energy consumption of the vehicle is more facilitated.

Further, in order to effectively control the opening and closing of the air supply channel to meet the air supply requirements of different working conditions, a first air door 204 is arranged in the main channel, the first air door 204 is positioned between the second sub-channel and the first sub-channel, and the first air door 204 is used for selectively opening and closing the second sub-channel and/or the first sub-channel; or opening the first and second sub-channels simultaneously. Specifically, the first damper 204 can control the on-off of the second sub-passage, and when the defogging operation is required, the first damper 204 is opened to a specific position to open the first sub-passage and the second sub-passage, so that the air can flow into the second sub-passage to exchange heat with the second in-vehicle heat exchanger 110 to perform the defogging operation.

Preferably, a switchable vent (not labeled) is further provided between the first sub-channel and the second sub-channel. Specifically, in order to improve the defogging efficiency, especially in the cooling mode, the air in the first sub-channel enters the second sub-channel through the vent to increase the air output of the defogging air outlet 205, so as to improve the defogging efficiency.

To control the vent opening/closing, a second damper 207 may be disposed between the first sub-passage and the second sub-passage, and the second damper 207 may be used to selectively open the vent opening. Wherein the second damper 207 may also be used to selectively open the vent and close the outlet 206. Specifically, the vent and the air-conditioning outlet 206 can be selectively opened and closed by the second damper 207, and when the air-conditioning outlet 206 is in an open state, the vent is in a closed state, and conversely, when the air-conditioning outlet 206 is in a closed state, the vent is in an open state. And with regard to the arrangement position of the vents, the vents are located rearward of the first interior heat exchanger 111 and the second interior heat exchanger 110 in the air flow direction.

The invention also provides a control method of the vehicle heat pump air conditioning system, which comprises the following steps:

when the cooling mode is executed, the four-way valve 103 controls the second indoor heat exchanger 110 to be connected with the first indoor heat exchanger 111 in series; the four-way valve 103 controls the second interior heat exchanger 110 to be connected in series with the exterior heat exchanger 101 when the heating mode is performed.

Specifically, in the heating and cooling modes, the second indoor heat exchanger 110 is connected in series with the first indoor heat exchanger 111 or the outdoor heat exchanger 101 through the four-way valve 103, so that a low-temperature refrigerant flows into the second indoor heat exchanger 110, and the defogging requirement is met.

The concrete control process for demisting in the refrigeration mode comprises the following steps: the first air door 204 opens the first sub-channel and the second sub-channel, the second air door 207 closes the vent and opens the air-conditioning air outlet 206, the air-conditioning air outlet 206 outputs cold air to adjust the temperature in the vehicle, and the demisting air outlet 205 outputs dry cold air to demist the glass of the vehicle; and the second damper 207 opens the vent and closes the air-conditioning outlet 206 in the case where the in-vehicle temperature reaches the set temperature. Specifically, as shown in fig. 3, the heat pump air conditioning system for a vehicle is in a cooling mode, at this time, the H port and the I port of the four-way valve 103 are connected, the K port and the J port are connected, and the system starts cooling. As shown in fig. 4, when the defogging operation is started during the cooling process, the first damper 204 is opened, the second damper 207 is opened, and the air outlet 206 is closed. When the temperature in the vehicle reaches the set temperature and the defogging is still opened, the second damper 207 closes the air-conditioning outlet 206 and opens the vent.

The concrete control process for demisting in the heating mode comprises the following steps: the first air door 204 opens the first sub-channel and the second sub-channel, the second air door 207 closes the vent and opens the air-conditioning air outlet 206, the air-conditioning air outlet 206 outputs hot air to adjust the temperature in the vehicle, and the demisting air outlet 205 outputs dry cold air to demist the glass of the vehicle; and after the demisting is completed, the first damper 204 closes the second sub-passage and keeps the first sub-passage open.

Specifically, as shown in fig. 5, the heat pump air conditioning system for a vehicle is in a heating mode, at this time, H and K of the four-way valve 103 are turned on, and the system starts heating. As shown in fig. 6, after the defogging process is started during the heating process, the first damper 204 opens the first sub-channel and the second sub-channel to simultaneously open the defogging air outlet 205, and the second damper 207 closes the air outlet and opens the air conditioning air outlet 206. The air-conditioning outlet 206 blows hot air, and the demisting outlet 205 blows dry cold air. When the temperature in the vehicle reaches the set temperature and the defogging is still opened in the heating process: the second damper 207 opens the vent and closes the air outlet 206. During the defogging process in the heating mode, the second in-vehicle heat exchanger 110 absorbs heat in the vehicle to improve the evaporation pressure of the second in-vehicle heat exchanger 110, so as to improve the condensation pressure of the inner heat exchanger 111, and finally the heat absorbed by the second in-vehicle heat exchanger 110 is returned to the vehicle through the first in-vehicle heat exchanger 111, so that the excessive temperature reduction in the vehicle during the defogging process is reduced to the maximum extent, and the energy consumption is reduced.

Further, the control method further comprises: in the single defogging mode, the four-way valve 103 controls the second interior heat exchanger 110 to be connected in series with the exterior heat exchanger 101, the first damper 204 opens the first sub-path and the second sub-path, and the second damper 207 opens the vent and closes the air-conditioning outlet 206.

The system starts demisting, wherein one part of air in the air inlet 202 passes through the second vehicle interior heat exchanger 110 and then becomes low-temperature dry air, the other part of air passes through the first vehicle interior heat exchanger 111 and then becomes high-temperature low-humidity air, the two air are mixed into comfortable and dry air in the second sub-channel, and after the air is blown to the windshield of the automobile, fog beads on the automobile glass are vaporized, so that demisting is realized.
