DETAILED DESCRIPTION

[0057] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution in the embodiment of the present application will be described in more detail below in conjunction with the drawings in the preferred embodiment of the present application. Obviously, the described embodiment is only a part of the embodiment of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0058] It should be noted that in the description of the embodiments of the present application, terms such as "upper", "lower", "inside" and "outside" indicating orientation or positional relationships are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of description. They do not indicate or imply that the device or component must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the embodiments of the present application.

[0059] In addition, it should be noted that the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or suggesting relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of this application, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0060] In this application, unless otherwise clearly specified and limited, the terms "installation", "connection", "fixation" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or mutual communication; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

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

[0062] In view of this, the temperature control system, vehicle and vehicle cab temperature control method provided by the present application, the temperature control system includes a compressor, a condenser, a flow unit, an evaporator, a vehicle refrigerator and a control unit. Among them, the compressor, the condenser, the flow unit and the evaporator are circulated and connected to form a first circulation loop, and heat exchange is performed 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, 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.

[0063] The present application is described in detail below with reference to the accompanying drawings and specific embodiments.

[0064] See also Figure 1 The present application provides a temperature adjustment system, which can be used to adjust the temperature of a vehicle cab. The temperature adjustment system may 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 circulated and connected to form a first circulation loop. The vehicle refrigerator 500, the compressor 100 and the evaporator 400 form a second circulation loop.

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

[0067] It is understandable that in order to adjust the temperature in the vehicle cab, the temperature adjustment system may include a first circulation loop, which uses the compressor 100 as a power source to drive the refrigerant to flow through the condenser 200, the flow unit 300 in sequence, and finally to the evaporator 400 to complete the cycle. 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 and condenses into a liquid in the condenser 200. When the liquid refrigerant flows through the flow unit 300, its flow rate is controlled by the flow unit 300 to meet actual needs, and then the refrigerant enters the evaporator 400. Heat is absorbed in the evaporator 400 and converted into a low temperature and low pressure state, thereby achieving heat exchange with the vehicle cab and effectively reducing the temperature in the vehicle cab.

[0068] In addition, the temperature control system may also include a second circulation loop, which connects the vehicle refrigerator 500 with the compressor 100 and the evaporator 400 to form an independent refrigeration cycle. This arrangement enhances the versatility of the temperature control system, so that the vehicle refrigerator 500 can utilize the redundant energy inside the vehicle refrigerator 500 to achieve cooling of the vehicle cab while meeting the user's needs for refrigerating items.

[0069] The vehicle refrigerator 500 may be a freezer, a portable refrigerator, etc., which is not limited in this embodiment.

[0070] In order to ensure the stable operation and efficient regulation of the temperature regulation system, the temperature regulation system can also be provided with a control unit 600. The control unit 600 is connected to the compressor 100 and the flow unit 300, and timely adjusts the operating power of the compressor 100 and the valve opening of the flow unit 300 by real-time detection of parameters such as the vehicle cab temperature and the refrigerant flow rate, so as to achieve accurate control of the cooling capacity. In this way, the response speed and 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 adjustment system, the first circulation loop performs heat exchange 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, the second circulation loop can be started to perform heat exchange with the vehicle cab to reduce the temperature in the vehicle cab. In this way, by using the redundant energy in 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] See also Figure 1 In some embodiments, the compressor 100 may include a first compression module 110 and a second compression module 120. The first compression module 110 is cyclically connected with the condenser 200, the flow unit 300 and the evaporator 400 to form a first circulation loop. The second compression module 120 is cyclically connected with the vehicle refrigerator 500 and the evaporator 400 to form a second circulation loop.

[0073] In specific implementation, the first compression module 110 is connected to the condenser 200, the flow unit 300 and the evaporator 400 to jointly construct a first circulation loop for efficient operation. 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 control of the flow unit 300, the refrigerant enters the evaporator 400 at an appropriate 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 control system to provide cooling for the interior of the vehicle cab.

[0074] On the other hand, the second compression module 120 is used to connect with the vehicle refrigerator 500 and the evaporator 400 to form a second circulation loop. In the second circulation loop, the redundant energy (such as redundant refrigerant) in the vehicle refrigerator 500 can be pressurized and converted into high-temperature and high-pressure gas through the second compression module 120, and then enter the evaporator 400, absorb heat in the evaporator 400 and evaporate into low-temperature and low-pressure refrigerant. In addition, a refrigerant output device (such as a wind output device, of course, this embodiment is not limited here) 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 through the refrigerant output device. In this way, the redundant energy in the vehicle refrigerator 500 is recycled, and the purpose of reducing vehicle fuel consumption and improving energy utilization is achieved.

[0075] See also Figure 1In some embodiments, the control unit 600 may include a compressor control module 610 and a flow control module 620. The compressor control module 610 is connected in communication with the compressor 100 to control the operation state of the first compression module 110 and the second compression module 120. The flow control module 620 is connected 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 establishes a communication connection with the compressor system 100 to control the compressor system 100. This arrangement ensures that the control module 600 can obtain the working status information of the compressor 100 in real time and issue control instructions accordingly. Specifically, the compressor control module 610 can regulate the operating status of the first compression module 110 and the second compression module 120 respectively, which may include starting, stopping, adjusting the speed, and optimizing the working mode. Through the real-time control of the compressor control module 610, it can ensure that the first compression module 110 and the second compression module 120 operate stably in the corresponding first circulation loop and the 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 a good energy efficiency ratio and refrigeration effect.

[0077] Furthermore, the flow control module 620 is used to accurately manage the refrigerant flow in the first circulation loop. The flow control module 620 is connected to the flow unit 300, and realizes dynamic adjustment of the refrigerant flow by real-time monitoring of flow data and sending control signals. The flow control module 620 can automatically adjust the flow of the refrigerant according to changes in external conditions such as the temperature control system load and ambient temperature, ensuring that the evaporator 400 can obtain sufficient refrigerant supply 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 control system can be effectively improved.

[0078] See also 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) may also be included. The first temperature detection device is used to obtain the ambient temperature in the cab and is connected to the control unit 600. The second temperature detection device is used to obtain the refrigerant temperature of the vehicle refrigerator and is connected to the control unit 600.

[0079] The control unit 600 is configured to control the operating states 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 status of the compressor 100 and the flow unit 300 in real time according to the detection results.

[0081] On the other hand, the second temperature detection device can be provided in the refrigerant chamber of the vehicle refrigerator 500, and the second temperature detection device can be used to detect the refrigerant temperature inside the vehicle refrigerator 500. By providing 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 information from the first temperature detection device and the second temperature detection device, and can also synthesize the detection information of both or one of the first temperature detection device and the second temperature detection device to send a control signal. Specifically, when the temperature in the vehicle cab is high, the control unit 600 may increase the power output of the compressor 100 and adjust the flow unit 300 to increase the circulation volume 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-saving and efficient manner.

[0083] Based on the above embodiments, an embodiment of the present application also provides a vehicle, including the temperature control system provided by any of the above embodiments.

[0084] The vehicle may be a truck, a fire truck, an engineering vehicle, etc., but this embodiment is not limited thereto.

[0085] Based on the above embodiment, the present application also provides a vehicle cab temperature adjustment method, which can be applied to the above temperature adjustment system. Figure 2 , the temperature adjustment method may include the following steps:

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

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

[0088] In specific implementation, firstly, step S101 is performed, that is, the ambient temperature of the cab is obtained. The ambient temperature information of the cab can be captured in real time and accurately through the first temperature detection device arranged in the cab.

[0089] Then, step S102 is entered, and the operating state of the compressor 100 and the flow unit 300 is accurately controlled according to the comparison result of the ambient temperature and the target temperature. 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 cabin needs to be cooled down. At this time, the control unit 600 will issue an instruction to adjust the temperature control system accordingly, so that the temperature control system can lower the temperature in the cabin 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 may maintain the current power of the compressor 100 or appropriately reduce the power to avoid over-cooling. In addition, the flow rate of the flow unit 300 will also be adjusted accordingly to maintain the stability and energy efficiency of the temperature control system.

[0092] In some embodiments, according to step S102: the operating state of the compressor 100 and the flow unit 300 is controlled according to the comparison result between the ambient temperature and the target temperature, see Figure 2 and Figure 3 , which 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, when the operating states of the compressor 100 and the flow unit 300 are controlled according to the comparison result between the ambient temperature and the target temperature, 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, the ambient temperature data in the cab collected in real time by the first temperature detection device is compared with the target temperature, and the temperature control system recognizes that the current ambient temperature in the cab is lower than the preset target temperature range.

[0097] Then, entering step S202, the control unit 600 sends a command 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 refrigerant by the compressor 100 is reduced, thereby reducing the overall cooling capacity of the temperature control system, and preventing the ambient temperature in the cab from further decreasing.

[0098] In addition, in order to adjust the power of the compressor 100, the control unit 600 will also send instructions to the flow unit 300 through the flow control module 620 to reduce the opening of the flow unit 300. This arrangement reduces the circulation amount of the refrigerant in the temperature control system, further slows down the absorption and transfer speed of heat, and helps to stabilize the ambient temperature in the cab, so that the ambient temperature gradually approaches and is maintained within the target temperature range.

[0099] Based on step S201 and step S202, see Figure 3 , and may also include:

[0100] Step S203: Determine that the ambient temperature is lower than the target temperature and maintain the temperature for a first preset time period.

[0101] That is to say, after confirming that the ambient temperature is lower than the target temperature, the temperature control system will not immediately take extreme measures (such as completely shutting down the compressor 100). The temperature control system will detect and record the duration of the ambient temperature being lower than the target temperature, and compare the duration with the preset first preset time length.

[0102] Step S204: controlling the first compression module 110 of the compressor 100 to be turned off.

[0103] If it is determined in step S203 that the ambient temperature has been below the target temperature for a first preset time, it indicates that further measures need to be taken in the cab to prevent the ambient temperature from continuing to drop. At this time, the control unit 600 sends an instruction to the compressor 100 to control its first compression module 110 to be completely shut down. In this way, the compression and circulation path of the refrigerant will be completely cut off, thereby quickly stopping the refrigeration process, which is conducive to stabilizing the ambient temperature in the cab.

[0104] Among them, the first preset duration can be set according to actual needs, and this embodiment does not limit it here.

[0105] In some embodiments, according to step S102: the operating state of the compressor 100 and the flow unit 300 is controlled according to the comparison result between the ambient temperature and the target temperature, see Figure 2 and Figure 4 , and may also include:

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

[0107] That is, in step S102, when the operating states of the compressor 100 and the flow unit 300 are controlled according to the comparison result between the ambient temperature and the target temperature, 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 in the cab collected in real time by the first temperature detection device with the target temperature, the temperature control system will recognize that the current ambient temperature in the cab is higher than the preset target temperature range.

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

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

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

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

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

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

[0114] Step S305: If the refrigerant temperature is lower than the target temperature, the first compression module 110 of the compressor 100 is controlled to be turned off, and the second compression module 120 of the compressor 100 is controlled to be turned on until the ambient temperature is equal to the target temperature and maintained for a second preset time.

[0115] It is understandable that when the refrigerant temperature is higher than the target temperature, step S304 is executed, and the temperature adjustment system causes 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 multiple factors such as energy efficiency ratio, refrigeration efficiency, and noise control, with the purpose of reducing the refrigerant temperature in a more economical and efficient manner, which is not limited in this embodiment.

[0116] On the contrary, if the refrigerant temperature is lower than the target temperature, step S305 is executed. When executing step S305, the control unit 600 can control the first compression module 110 of the compressor 100 to be turned off to save energy. Subsequently, the control unit 600 can control the start-up of the second compression module 120 of the compressor 100. By enabling the second circulation loop, the redundant refrigerant in the vehicle refrigerator 500 can be used to cool the vehicle cab until the ambient temperature drops to the same as the target temperature, and ensure that this state is maintained for at least a second preset time to ensure the stability of the ambient temperature. In this way, by utilizing the redundant refrigerant in the vehicle refrigerator 500, the vehicle's fuel consumption can be reduced and the energy utilization rate can be effectively improved.

[0117] The second preset duration may be set according to actual needs, and this embodiment does not limit this.

[0118] In addition, the second compression module 120 can use an energy-saving compressor. Compared with the first compression module 110, the second compression module 120 can save energy 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 simultaneously, so that the refrigeration effect can be improved. And by setting the second circulation loop, the long-term operation of the first circulation loop can be avoided, so that the service life of the temperature control system can be increased.

[0120] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
