DETAILED DESCRIPTION

[0057] The embodiments of the present application provide an energy recovery system, method, device, equipment and medium, and solve the technical problem that the heat generated by the air compressor is lost and the heat utilization rate is not high in the prior art.

[0058] The technical solutions of the embodiments of the present application are as follows to solve the above technical problems:

[0059] This embodiment obtains the target operating state of the air conditioning circuit; when the target operating state is heating, obtains the actual operating state of the air compressor 16; when the actual operating state of the air compressor 16 is stagnant, controls the air compressor stagnant heating sub-circuit to operate; and when the actual operating state of the air compressor 16 is running, controls the air compressor running heating sub-circuit to operate. As can be seen, this embodiment utilizes the heat exchanger 12 to recover the heat generated by the air compressor 16. When the air conditioning circuit requires the heat generated by the air compressor 16, the refrigerant in the air conditioning circuit is passed through the heat exchanger 12 to improve the utilization rate of the heat generated by the air compressor 16. This also reduces the consumption of on-board electrical energy during the heating process of the air conditioning circuit, thereby increasing the vehicle's range. This embodiment couples the air compressor 16 with the air conditioning circuit, effectively utilizing the waste heat of the compressed air, improving the heating comfort of the passenger compartment, reducing the overall vehicle energy consumption, and thus increasing the vehicle's range in low temperatures.

[0060] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0061] First, the term "and / or" as used herein simply describes a relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A alone, A and B together, or B alone. Furthermore, the character " / " in this document generally indicates an "or" relationship between the associated objects.

[0062] This embodiment provides Figure 1 An energy recovery system shown, the system includes a controller (not shown) Figure 1 ), the air conditioning circuit and the air supply circuit, the air conditioning circuit and the air supply circuit achieve heat exchange through the heat exchanger 12;

[0063] The air conditioning circuit includes a gas-liquid separation tank 1, a compressor 2, a fourth stop valve 7, an in-vehicle condenser 9, an evaporator 8, a first electronic expansion valve 14, a second electronic expansion valve 13, a full-pass throttle valve 11, a heat exchanger 12, a third stop valve 10, an outdoor heat exchanger 5, and a second stop valve 3;

[0064] The air-liquid separation tank 1, the compressor 2, the first stop valve 4, the outdoor heat exchanger 5, the full-pass throttle valve 11, the first electronic expansion valve 14, the evaporator 8, and the air-liquid separation tank 1 of the air-conditioning circuit are connected in sequence to form a refrigeration sub-circuit;

[0065] The air-liquid separation tank 1, compressor 2, fourth stop valve 7, in-vehicle condenser 9, full-pass throttle valve 11, outdoor heat exchanger 5, second stop valve 3, and air-liquid separation tank 1 of the air conditioning circuit are connected in sequence to form an air compressor stagnation heating sub-circuit;

[0066] The air-liquid separation tank 1, the compressor 2, the fourth stop valve 7, the in-vehicle condenser 9, the second electronic expansion valve 13, the heat exchanger 12, the third stop valve 10, and the air-liquid separation tank 1 of the air conditioning circuit are sequentially connected and form an air compressor running heating sub-circuit.

[0067] The full-through throttle valve 11 is connected in parallel between the heat exchanger 12 and the second electronic expansion valve 13.

[0068] The air supply circuit includes an air filter 15, an air compressor 16, a heat exchanger 12, an intercooler 17, a humidifier 18, and a stack 19 connected in sequence.

[0069] In actual operation, in addition to the above-mentioned circuits and related devices, some sensors are also correspondingly provided. For example Figure 1 The corresponding pressure sensor P, temperature sensor T1, temperature and pressure sensor PT, and temperature sensor T2 for measuring the temperature of the air supply circuit. The related sensors can be set according to the actual situation, and the embodiment does not limit this.

[0070] The controller is electrically connected with the refrigeration sub-circuit, the air compressor stalling heating sub-circuit, the air compressor running heating sub-circuit, and the air supply circuit respectively, and the controller is used to control the refrigeration sub-circuit, the air compressor stalling heating sub-circuit, and the air compressor running heating sub-circuit to be turned on or turned off respectively.

[0071] Specifically, the controller is electrically connected with the following devices:

[0072] The second stop valve 3, the first stop valve 4, the outdoor heat exchanger 5, the electronic fan 6, the fourth stop valve 7, the third stop valve 10, the full-through throttle valve 11, the second electronic expansion valve 13, the first electronic expansion valve 14, the air compressor 16, P, T1, PT, and T2, and other electronic control devices.

[0073] The embodiment couples the air conditioning circuit and the air supply circuit through the heat exchanger 12, so that the air conditioning circuit recovers the heat of the air compressor 16 in the air supply circuit in the heating state, improves the heat utilization rate of the air compressor 16, reduces the energy consumption of the vehicle, and prolongs the driving range of the vehicle.

[0074] Based on the same inventive concept, the embodiment provides an energy recovery method as shown in Figure 2 The method is applied to the controller of the heat recovery system provided in the foregoing, and specifically applied to an energy recovery system, and the method includes steps S21-S24.

[0075] Step S21, obtaining a target operating state of an air conditioning circuit;

[0076] Step S22, when the target operating state is a heating state, obtaining an actual working state of an air compressor 16.

[0077] Step S23, when the actual working state of the air compressor 16 is the stagnation state, control the air compressor to run in the stagnation heating sub-circuit;

[0078] Step S24, when the actual working state of the air compressor 16 is the running state, control the air compressor to run in the running heating sub-circuit.

[0079] The heat recovery method provided in this embodiment can be executed by the vehicle-mounted controller of the vehicle where the air conditioning circuit is located, or by the air conditioning controller corresponding to the air conditioning circuit. This embodiment will be described below taking the air conditioning controller as the main execution body.

[0080] Regarding step S21, the target running state of the air conditioning circuit is obtained.

[0081] The running state of the air conditioning circuit includes the working state and the non-working state, and the working state includes the refrigeration state and the heating state. The state identifier corresponding to the air conditioning circuit can be read, and the running state of the air conditioning circuit can be determined based on the state identifier.

[0082] When the target running state is the non-working state, it means that the heat generated by the air compressor 16 needs to be lost, the air conditioning circuit does not run, and although the heat generated by the air compressor 16 will be transferred to the heat exchanger 12, since the air conditioning circuit does not run, the heat in the heat exchanger 12 has little effect on the air conditioning circuit.

[0083] When the target running state is the refrigeration state, control the refrigeration sub-circuit to run. That is, when the target running state is the refrigeration state, control the fourth stop valve 7, the second stop valve 3, the third stop valve 10, and the second electronic expansion valve 13 to be closed, and control the first stop valve 4, the full-pass throttling valve 11, and the first electronic expansion valve 14 to be turned on, so that the refrigeration sub-circuit is in the on state.

[0084] In the refrigeration state, the air conditioning circuit does not need to recover the heat generated by the air compressor 16, and the air conditioning circuit can rely on the outdoor heat exchanger 5 to refrigerate, and the electronic fan 6 can change the airflow direction of the outdoor heat exchanger 5 to assist refrigeration. This embodiment uses the full-pass throttling valve 11 to transfer the refrigerant in the air conditioning circuit, so that the refrigerant in the air conditioning circuit does not pass through the heat exchanger 12. Even if the air compressor 16 is in the running process, that is, even if the air compressor 16 is generating heat while compressing air for the electric pile 19, the heat in the heat exchanger 12 has little effect on the air conditioning circuit. This can greatly reduce the effect of the heat absorbed by the heat exchanger 12 from the air compressor 16 on the air conditioning circuit, and reduce the vehicle-mounted electric energy consumed by the air conditioning circuit for refrigeration.

[0085] When the target running state is the heating state, step S22 can be continued.

[0086] As to step S22, when the target operation state is the heating state, the actual working state of the air compressor 16 is acquired.

[0087] The operation state of the air compressor 16 includes the stagnation state and the running state. On the premise that the target operation state is the heating state, when the actual working state of the air compressor 16 is the stagnation state, step S23 is continued to be executed, and when the actual working state of the air compressor 16 is the running state, step S24 is continued to be executed.

[0088] As to step S23, when the actual working state of the air compressor 16 is the stagnation state, the air compressor stagnation heating sub-circuit is controlled to operate.

[0089] When the actual working state of the air compressor 16 is the stagnation state, it means that the air compressor 16 does not work, that is, the air compressor 16 does not compress air for the electric pile 19, and the air compressor 16 basically does not generate heat. At this time, the air conditioner circuit mainly relies on the outdoor heat exchanger 5 to realize heating, and the electronic fan 6 can change the airflow direction of the outdoor heat exchanger 5 to assist heating.

[0090] Specifically, when the actual working state of the air compressor 16 is the stagnation state, the fourth stop valve 7, the full-through throttling valve 11 and the second stop valve 3 are controlled to be turned on, and the first stop valve 4, the first electronic expansion valve 14, the second electronic expansion valve 13 and the third stop valve 10 are controlled to be turned off, so that the air compressor stagnation heating sub-circuit is in the on state.

[0091] The full-through throttling valve 11 is used in the embodiment to transmit the refrigerant in the air conditioner circuit, so that the refrigerant in the air conditioner circuit does not pass through the heat exchanger 12, thereby reducing the heat absorption of the refrigerant in the air conditioner circuit by the heat exchanger 12, ensuring that the heating efficiency of the air conditioner circuit is relatively high, reducing the waste of vehicle-mounted electric energy in the heating process of the air conditioner circuit, and improving the electric energy utilization rate.

[0092] As to step S24, when the actual working state of the air compressor 16 is the running state, the air compressor running heating sub-circuit is controlled to operate.

[0093] When the actual working state of the air compressor 16 is the running state, it means that the air compressor 16 is working and compressing air for the electric pile 19, and the air compressor 16 generates a large amount of heat. At this time, the air compressor running heating sub-circuit is controlled to operate, and the heat in the heat exchanger 12 can be recovered, that is, the heat generated by the air compressor 16 is recovered.

[0094] When the actual working state of the air compressor 16 is the running state, the fourth stop valve 7, the second electronic expansion valve 13, and the third stop valve 10 are controlled to be turned on, and the first stop valve 4, the first electronic expansion valve 14, the full-pass throttling valve 11, and the second stop valve 3 are controlled to be turned off, so that the air compressor running heating sub-circuit is in the on state.

[0095] In this embodiment, the full-pass throttling valve 11 is closed, the refrigerant in the air conditioning circuit passes through the heat exchanger 12, and the heat of the air compressor 16 is recovered to the air conditioning circuit as much as possible, so as to improve the utilization rate of the heat of the air compressor 16, reduce the use amount of the vehicle-mounted electric energy for heating in the air conditioning circuit, prolong the vehicle cruising range, and improve the utilization rate of the vehicle-mounted electric energy.

[0096] Specifically, when the actual working state of the air compressor 16 is the running state, the target heating temperature of the passenger cabin space corresponding to the air conditioning circuit and the actual running temperature of the air compressor 16 can be obtained; then according to the target heating temperature and the actual running temperature, the target heating power of the air compressor circuit is determined, and the air compressor running heating sub-circuit is controlled to run at the target heating power.

[0097] When the actual running temperature is less than the target heating temperature, or when the actual running temperature is greater than the target heating temperature and the difference between the two is less than a preset temperature threshold, it means that the air conditioning circuit still needs to use the vehicle-mounted electric energy for heating on the premise of recovering the heat of the air compressor 16. In this case, the full-pass throttling valve 11 can be completely closed, so that all the refrigerant in the air conditioning circuit flows through the heat exchanger 12, and the refrigerant can absorb the heat recovered from the air compressor 16 in the heat exchanger 12, thereby improving the utilization rate of the heat of the air compressor 16 and reducing the use amount of the vehicle-mounted electric energy in the air conditioning circuit, thereby reducing the energy consumption of the heating of the passenger cabin space.

[0098] When the actual running temperature is greater than the target heating temperature and the difference between the two is greater than the preset temperature threshold, it means that the heat recovered from the air compressor 16 can basically cover the energy consumption of the air conditioning circuit for heating the passenger cabin temperature to the target heating temperature, so as to maximize the consumption of the air conditioning equipment for the vehicle-mounted electric energy, on the one hand, improve the utilization rate of the heat of the air compressor 16, and on the other hand, reduce the consumption of the vehicle-mounted electric energy and prolong the vehicle cruising range.

[0099] When the actual running temperature is greater than the target heating temperature and the difference between the two is greater than the preset temperature threshold, the air compressor running heating circuit needs to be controlled to run, and when the heat provided by the heat exchanger 12 is too much to cause the temperature of the air conditioning circuit to be too high, the full-pass throttling valve 11 can be appropriately turned on, so that part of the refrigerant in the air conditioning circuit does not pass through the heat exchanger 12, thereby reducing the heat obtained by the refrigerant in the air conditioning circuit from the heat exchanger 12, so as to reduce the temperature in the passenger cabin to the target heating temperature.

[0100] To sum up, the embodiment acquires the target running state of the air conditioning loop; when the target running state is the heating state, acquires the actual working state of the air compressor 16; when the actual working state of the air compressor 16 is the stagnation state, controls the air compressor to run in the stagnation heating sub-loop; when the actual working state of the air compressor 16 is the running state, controls the air compressor to run in the running heating sub-loop. It can be seen that the embodiment recycles the heat generated by the air compressor 16 by using the heat exchanger 12, and when the air conditioning loop needs to use the heat generated by the air compressor 16, the refrigerant in the air conditioning loop flows through the heat exchanger 12, so as to improve the utilization rate of the heat of the air compressor 16, and meanwhile, the consumption of the vehicle-mounted electric energy in the heating process of the air conditioning loop is reduced, thereby the cruising range of the vehicle can be increased. The embodiment couples the air compressor 16 with the air conditioning loop, effectively utilizes the waste heat of the compressed air, improves the heating comfort of the passenger compartment, reduces the energy consumption of the vehicle, and thereby improves the cruising range of the vehicle at low temperature.
