DETAILED DESCRIPTION

[0057] In order to make the purposes, technical solutions and advantages of the present application more clear, the technical solutions in the embodiments of the present application will be described in more detail below by combining the drawings in the preferred embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without any creative work under the premise of the present application, all belong to the scope of protection of the present application.

[0058] It should be noted that in the description of the embodiments of the present application, the terms of orientation or position relationship such as “upper”, “lower”, “inner”, “outer” and the like are based on the direction or position relationship shown in the drawings, and are only for the convenience of description, and do not indicate or imply that the device or component must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present application.

[0059] In addition, it needs to be explained that the terms "first", "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features, so the features with "first", "second" can be explicitly or implicitly included one or more of the features, and in the description of the present application, the meaning of "multiple" is two or more, unless otherwise explicitly specified and limited.

[0060] In the present application, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "fixing" and the like should be understood in a broad sense, for example, it can be fixed connection, or detachable connection, or integrated; it can be mechanical connection, or electrical connection or can communicate with each other; it can be direct connection, or indirect connection through intermediate medium, it can be the internal communication of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0061] In the related art, the vehicle air conditioning system generally includes a compressor, an evaporator and a condenser. The compressor compresses the refrigerant into high-temperature and high-pressure gas, which is sent to the condenser to release heat and condense into liquid. Then, the refrigerant enters the evaporator to evaporate and absorb heat at low pressure, thereby reducing the temperature in the cab. However, the above vehicle air conditioning system has high fuel consumption and low energy utilization rate.

[0062] Therefore, the present application provides a temperature regulation system, a vehicle and a temperature regulation method for a vehicle cab. The temperature regulation system includes a compressor, a condenser, a flow unit, an evaporator, a vehicle refrigerator and a control unit. The compressor, the condenser, the flow unit and the evaporator are in circulation communication to form a first circulation loop, and heat exchange with the vehicle cab through the first circulation loop to effectively reduce the temperature in the vehicle cab. The vehicle refrigerator, the compressor and the evaporator form a second circulation loop. When the second circulation loop is enabled, the redundant refrigerant in the vehicle refrigerator flows through the compressor and the evaporator to achieve cooling of the vehicle cab. In this way, the redundant energy inside the vehicle refrigerator 500 is used to cool the vehicle cab, which can reduce fuel consumption of the vehicle and effectively improve energy utilization rate.

[0063] The present application will be described in detail below in conjunction with the drawings and specific embodiments.

[0064] Referring to Figure 1 The present application provides a temperature regulation system which can be used to regulate the temperature of a vehicle cab. The temperature regulation system can include a compressor 100, a condenser 200, a flow unit 300, an evaporator 400, a vehicle refrigerator 500 and a control unit 600.

[0065] The compressor 100, the condenser 200, the flow unit 300 and the evaporator 400 are cyclically communicated to form a first circulation loop. The vehicle-mounted refrigerator 500, the compressor 100 and the evaporator 400 form a second circulation loop.

[0066] The temperature regulation system is configured to exchange heat with a cab (not shown in the figure) through the first circulation loop and the second circulation loop respectively. The control unit 600 is connected to the compressor 100 and the flow unit 300 respectively to control the operating states of the compressor 100 and the flow unit 300.

[0067] It can be understood that, in order to regulate the temperature in the cab of the vehicle, the temperature regulation system can include the first circulation loop, which takes the compressor 100 as a power source to drive the refrigerant to flow through the condenser 200, the flow unit 300 and finally to the evaporator 400 to complete the circulation. During the operation of the first circulation loop, the compressor 100 is used to increase the pressure and temperature of the refrigerant so that the refrigerant releases heat in the condenser 200 and condenses into a liquid state. When the liquid refrigerant flows through the flow unit 300, its flow is controlled by the flow unit 300 to meet the actual demand, and then the refrigerant enters the evaporator 400. In the evaporator 400, heat is absorbed and converted into a low-temperature and low-pressure state, thereby realizing heat exchange with the cab of the vehicle and effectively reducing the temperature in the cab of the vehicle.

[0068] In addition, the temperature regulation system can also include the second circulation loop, which connects the vehicle-mounted refrigerator 500 with the compressor 100 and the evaporator 400 to form an independent refrigeration cycle. In this way, the multifunctionality of the temperature regulation system is enhanced, so that the vehicle-mounted refrigerator 500 meets the user's demand for refrigeration while utilizing the redundant energy inside the vehicle-mounted refrigerator 500 to achieve cooling in the cab of the vehicle.

[0069] The vehicle-mounted refrigerator 500 can be a refrigeration box, a portable refrigerator, etc., which is not limited in the embodiment.

[0070] In order to ensure stable operation and efficient regulation of the temperature regulation system, the temperature regulation system can also be provided with the control unit 600. The control unit 600 is connected to the compressor 100 and the flow unit 300, and adjusts the operating power of the compressor 100 and the valve opening degree of the flow unit 300 in time by detecting the temperature in the cab of the vehicle, the flow of the refrigerant and other parameters in real time, so as to realize accurate control of the refrigeration capacity. In this way, the response speed and the regulation accuracy of the temperature regulation system are improved, the energy consumption is effectively reduced, and the overall energy efficiency is improved.

[0071] In this way, by setting the first circulation loop and the second circulation loop in the temperature regulation system, the first circulation loop exchanges heat with the vehicle cab to reduce the temperature in the vehicle cab. When the second circulation loop, that is, when the vehicle refrigerator 500 has redundant energy inside, the second circulation loop can be started to exchange heat with the vehicle cab to reduce the temperature in the vehicle cab, so that by using the redundant energy inside the vehicle refrigerator 500 to cool the vehicle cab, the vehicle fuel consumption can be reduced, and the energy utilization rate can be effectively improved.

[0072] Referring to Figure 1 In some embodiments, the compressor 100 can include a first compression module 110 and a second compression module 120. The first compression module 110 is in circulation communication with the condenser 200, the flow unit 300, and the evaporator 400 to form a first circulation loop. The second compression module 120 is in circulation communication with the vehicle refrigerator 500 and the evaporator 400 to form a second circulation loop.

[0073] In a specific implementation, the first compression module 110 is connected with the condenser 200, the flow unit 300, and the evaporator 400 to jointly build a first circulation loop that operates efficiently. In the first circulation loop, the refrigerant is pressurized in the first compression module 110 and converted into a high-temperature and high-pressure gas, and then flows through the condenser 200 to release heat and condense into a liquid. Then, under the regulation of the flow unit 300, the refrigerant enters the evaporator 400 at a suitable flow rate, absorbs heat in the evaporator 400, and evaporates into a low-temperature and low-pressure gas, thereby completing a refrigeration cycle. The first circulation loop is mainly used to realize the refrigeration function of the temperature regulation system to provide cold energy for the inside of the vehicle cab.

[0074] On the other hand, the second compression module 120 is used to be connected with the vehicle refrigerator 500 and the evaporator 400 to form a second circulation loop. In the second circulation loop, the redundant energy (for example, redundant refrigerant) in the vehicle refrigerator 500 can be pressurized by the second compression module 120 and converted into a high-temperature and high-pressure gas, and then enters the evaporator 400 to absorb heat and evaporate into a low-temperature and low-pressure refrigerant. In addition, a refrigerant output device (for example, a wind power output device, which is not limited in this embodiment) can be installed in the vehicle cab, and the low-temperature and low-pressure refrigerant formed in the evaporator 400 can be converted into cold air in the vehicle cab by the refrigerant output device, so that the cyclic utilization of the redundant energy in the vehicle refrigerator 500 is realized, and the purpose of reducing the vehicle fuel consumption and improving the energy utilization rate is achieved.

[0075] Referring to Figure 1In some embodiments, the control unit 600 can include a compressor control module 610 and a flow control module 620. The compressor control module 610 is in communication with the compressor system 100 to control the operating state of the first compression module 110 and the second compression module 120. The flow control module 620 is in communication with the flow unit 300 to control the refrigerant flow in the first circulation loop.

[0076] It should be noted that the compressor control module 610 is in communication with the compressor system 100 to control the compressor system 100. In this way, the control module 600 can obtain the working state information of the compressor 100 in real time and issue control instructions accordingly. Specifically, the compressor control module 610 can regulate the operating state of the first compression module 110 and the second compression module 120, including starting, stopping, adjusting the speed, and optimizing the working mode, etc. Through real-time control of the compressor control module 610, the first compression module 110 and the second compression module 120 can be ensured to run stably in the corresponding first circulation loop and second circulation loop, and the first compression module 110 and the second compression module 120 can be flexibly adjusted according to actual needs to achieve good energy efficiency ratio and refrigeration effect.

[0077] Further, the flow control module 620 is used for precise management of the refrigerant flow in the first circulation loop. The flow control module 620 is connected to the flow unit 300, and through real-time monitoring of flow data and sending of control signals, dynamic adjustment of the refrigerant flow is realized. The flow control module 620 can automatically adjust the flow size of the refrigerant according to changes in system load, ambient temperature, and other external conditions, to ensure that the evaporator 400 can obtain sufficient supply of refrigerant to fully absorb heat, while avoiding waste and unnecessary energy consumption. By setting the flow control module 620, the operating efficiency and performance of the temperature regulation system can be effectively improved.

[0078] Referring to Figure 1 In some embodiments, a first temperature detection device (not shown in the figure) and a second temperature detection device (not shown in the figure) can also be included. The first temperature detection device is used to obtain the ambient temperature inside the cab and is in communication with the control unit 600. The second temperature detection device is used to obtain the refrigerant temperature of the vehicle-mounted refrigerator and is in communication with the control unit 600.

[0079] The control unit 600 is configured to control the operating state of the compressor 100 and the flow unit 300 according to the detection results of the first temperature detection device and / or the second temperature detection device.

[0080] The first temperature detection device can be arranged in the vehicle cab to accurately capture and record the ambient temperature information in the vehicle cab. The ambient temperature information is then transmitted to the control unit 600 in real time, and the control unit 600 can control the operating state of the compressor 100 and the flow unit 300 in real time based on the detection results.

[0081] On the other hand, the second temperature detection device can be arranged in the refrigerant chamber of the vehicle refrigerator 500, and can be used to detect the refrigerant temperature inside the vehicle refrigerator 500. By arranging the second temperature detection device, accurate measurement of the refrigerant temperature is ensured, and real-time data is sent to the control unit 600. By comparing the detection results, the control unit 600 can determine whether to enable or disable the second circulation loop.

[0082] It should be noted that the control unit 600 can receive detection results from the first temperature detection device and the second temperature detection device, and can also integrate the detection information of both or one of the first temperature detection device and the second temperature detection device to issue a control signal. Specifically, when the temperature in the vehicle cab is too high, the control unit 600 can increase the power output of the compressor 100 and adjust the flow unit 300 to increase the circulation amount of the cooling medium, thereby accelerating the cooling process in the vehicle cab; on the other hand, if the refrigerant temperature in the vehicle refrigerator 500 is lower than the set value, the control unit 600 can enable the second circulation loop to cool the vehicle cab, and maintain the temperature in the vehicle cab within the preset temperature in an energy-efficient manner.

[0083] On the basis of the above-mentioned embodiments, the embodiments of the present application further provide a vehicle comprising the temperature regulation system provided by any of the above-mentioned embodiments.

[0084] The vehicle can be a truck, a fire truck, an engineering vehicle, etc., and the present embodiment is not limited thereto.

[0085] On the basis of the above-mentioned embodiments, the embodiments of the present application further provide a temperature regulation method for a vehicle cab, which can be applied to the above-mentioned temperature regulation system, and the temperature regulation method can comprise the following steps: Figure 2

[0086] Step S101: Obtain the ambient temperature of the cab.

[0087] Step S102: Control the operating state of the compressor 100 and the flow unit 300 according to the comparison result of the ambient temperature and the target temperature.

[0088] In specific implementation, first, step S101 is performed, i.e., the ambient temperature of the cab is obtained. The first temperature detection device arranged in the cab can accurately capture the ambient temperature information in the cab in real time. ​

[0089] Subsequently, the operation state of the compressor 100 and the flow unit 300 is precisely controlled according to the comparison result of the ambient temperature and the target temperature in step S102. In this process, the control unit 600 can have a preset target temperature range. Then, the control unit 600 compares the ambient temperature information provided by the first temperature detection device with the preset target temperature.

[0090] If the ambient temperature is higher than the upper limit of the target temperature range, the control unit 600 will determine that the cab needs to be cooled. At this time, the control unit 600 will issue instructions to make corresponding adjustments to the temperature regulation system. So that the temperature regulation system can reduce the temperature in the cab and adjust the ambient temperature to the target temperature range.

[0091] On the contrary, if the ambient temperature is lower than the lower limit of the target temperature range, the control unit 600 will determine that the temperature in the cab is too low. At this time, the control unit 600 can maintain the current power of the compressor 100 or appropriately reduce the power to avoid excessive refrigeration. And the flow of the flow unit 300 is also adjusted accordingly to maintain the stability and energy efficiency of the temperature regulation system.

[0092] In some embodiments, according to step S102: controlling the operation state of the compressor 100 and the flow unit 300 according to the comparison result of the ambient temperature and the target temperature, referring to Figure 2 and Figure 3 may include:

[0093] Step S201: If the ambient temperature is lower than the target temperature.

[0094] Step S202: Control the first compression module 110 of the compressor 100 to reduce the operating power, and control the flow unit 300 to reduce the opening degree.

[0095] That is, in step S102, that is, according to the comparison result of the ambient temperature and the target temperature to control the operation state of the compressor 100 and the flow unit 300, if the comparison result is that the ambient temperature is lower than the target temperature, steps S201 and S202 are executed to achieve precise temperature regulation.

[0096] First, in step S201, by comparing the ambient temperature data of the cab collected by the first temperature detection device in real time with the target temperature, the temperature regulation system can identify that the current ambient temperature of the cab is lower than the preset target temperature range.

[0097] Then, in step S202, the control unit 600 sends an instruction to the compressor 100 to adjust the operating state of the compressor 100. Specifically, the control unit 600 controls the first compression module 110 in the compressor 100 to reduce the operating power. In this way, the compression amount of the compressor 100 on the refrigerant is reduced, thereby reducing the overall refrigeration capacity of the temperature regulation system and avoiding further reduction of the ambient temperature in the cab.

[0098] In addition, in order to coordinate the adjustment of the power of the compressor 100, the control unit 600 also sends an instruction to the flow unit 300 through the flow control module 620 to reduce the opening of the flow unit 300. In this way, the circulation amount of the refrigerant in the temperature regulation system is reduced, further slowing down the absorption and transfer speed of heat, which helps to stabilize the ambient temperature in the cab and gradually approach and maintain the target temperature range.

[0099] On the basis of step S201 and step S202, referring to Figure 3 , the method can further include:

[0100] Step S203: determining that the ambient temperature is lower than the target temperature and maintaining for a first preset time length.

[0101] That is, after confirming that the ambient temperature is lower than the target temperature, the temperature regulation system does not immediately take extreme measures (such as completely shutting down the compressor 100), but detects and records the duration that the ambient temperature is lower than the target temperature, and compares the duration with the first preset time length.

[0102] Step S204: the first compression module 110 of the compressor 100 is controlled to be closed.

[0103] If it is confirmed through the judgment in step S203 that the state that the ambient temperature is lower than the target temperature has lasted for the first preset time length, it indicates that further measures need to be taken to avoid the ambient temperature in the cab from continuing to drop. At this time, the control unit 600 sends an instruction to the compressor 100 to control the first compression module 110 to be completely closed. In this way, the compression and circulation path of the refrigerant is completely cut off, thereby quickly stopping the refrigeration process and helping to stabilize the ambient temperature in the cab.

[0104] The first preset time length can be set according to actual needs, which is not limited in the embodiment.

[0105] In some embodiments, according to step S102: controlling the operating state of the compressor 100 and the flow unit 300 according to the comparison result of the ambient temperature and the target temperature, referring to Figure 2 and Figure 4 , the method can further include:

[0106] Step S301: If the ambient temperature is higher than the target temperature.

[0107] That is, in step S102, that is, according to the comparison result of the ambient temperature and the target temperature to control the operating state of the compressor 100 and the flow unit 300, if the comparison result is that the ambient temperature is higher than the target temperature, step S301 is executed. Specifically, by comparing the ambient temperature data collected in real time by the first temperature detection device with the target temperature, the temperature regulation system can identify that the current ambient temperature of the cab has exceeded the preset target temperature range.

[0108] Step S302: Obtain the refrigerant temperature of the vehicle-mounted refrigerator 500.

[0109] Specifically, the refrigerant temperature inside the vehicle-mounted refrigerator 500 is obtained by the second temperature detection device.

[0110] Step S303: Control the operating state of the compressor 100 and the flow unit 300 according to the comparison result of the refrigerant temperature and the target temperature.

[0111] In specific implementation, after the second temperature detection device obtains the refrigerant temperature inside the vehicle-mounted refrigerator 500, the refrigerant temperature information is transmitted to the control unit 600, and the refrigerant temperature is compared with the target temperature by the control unit 600 to determine whether to adjust the operating state of the compressor 100 and the flow unit 300.

[0112] In some embodiments, according to step S303: Control the operating state of the compressor 100 and the flow unit 300 according to the comparison result of the refrigerant temperature and the target temperature, see Figure 4 , which can include:

[0113] Step S304: If the refrigerant temperature is higher than the target temperature, control the first compression module 110 of the compressor 100 to operate at a preset power.

[0114] Step S305: If the refrigerant temperature is lower than the target temperature, control the first compression module 110 of the compressor 100 to be closed, and control the second compression module 120 of the compressor 100 to be opened until the ambient temperature is equal to the target temperature, and maintain for a second preset time.

[0115] It can be understood that when the refrigerant temperature is higher than the target temperature, step S304 is executed, and the temperature regulation system controls the first compression module 110 of the compressor 100 to operate at a preset power through the control unit 600. The preset power can be set according to the energy efficiency ratio, the refrigeration efficiency, and the noise control and other factors, the purpose is to reduce the refrigerant temperature in a more economical and efficient way, which is not limited in this embodiment.

[0116] On the contrary, if the refrigerant temperature is lower than the target temperature, step S305 is performed. When step S305 is performed, the control unit 600 can control the first compression module 110 of the compressor 100 to be turned off to save energy consumption. Then, the control unit 600 can control the second compression module 120 of the compressor 100 to be started. By enabling the second circulation loop, the temperature in the vehicle cab is lowered by using the redundant refrigerant in the vehicle refrigerator 500 until the ambient temperature is consistent with the target temperature, and the state is maintained for at least a second preset time to ensure the stability of the ambient temperature. In this way, by using the redundant refrigerant in the vehicle refrigerator 500, the fuel consumption of the vehicle can be reduced, and the energy utilization rate can be effectively improved.

[0117] The second preset time can be set according to actual needs, which is not limited in the embodiment.

[0118] In addition, the second compression module 120 can be an energy-saving compressor. Compared with the first compression module 110, the second compression module 120 can save energy consumption and has lower operating noise.

[0119] It should be noted that in specific implementation, the first circulation loop and the second circulation loop can also be operated at the same time, which can improve the refrigeration effect. By setting the second circulation loop, the first circulation loop can be avoided from being operated for a long time, so that the service life of the temperature adjusting system can be improved.

[0120] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand; it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
