To make the objects, technical solutions and advantages of the embodiments of the present application more clear, the embodiments of the present application will be further described in detail with reference to the accompanying drawings.
Before the embodiments of the present application are explained in detail, the application scenarios provided in the embodiments of the present application are introduced.
With the continuous development of science and technology, automobiles are also gradually becoming the tools of riding instead of walk for people. The automobile brings convenience to people going out, and meanwhile, the comfort of the automobile is also paid more and more attention to. For example, an automobile can adjust the internal temperature of the automobile through an air conditioning system, so that the internal temperature of the automobile meets the requirements of users. If people take the automobile in summer, the temperature in the automobile can be reduced, so that the cooling effect is achieved.
At present, an air conditioning system on an automobile can only adjust the internal integral temperature of the automobile, and cannot perform special heat preservation or cooling treatment on certain articles on the automobile, such as heat preservation treatment on food and hot soup and fresh-keeping treatment on fruits. Therefore, a user needs to prepare a heat preservation box or an ice bag for heat preservation or fresh-keeping treatment of the articles, so that the operation of the user is increased, and inconvenience is brought to the user.
Therefore, the original air conditioning system of the vehicle is utilized to provide the vehicle-mounted constant temperature control system, so that the temperature of the vehicle is reduced when the space of the vehicle is cooled. Moreover, the vehicle-mounted constant temperature control system can also realize the heating effect on the constant temperature box. Like this, through heating or cooling to the thermostated container, and then reach the effect of heating or cooling to article on the thermostated container to satisfy the user and keep warm or fresh-keeping demand to article. That is, the on-vehicle constant temperature control system that this application embodiment provided can intelligent adjustment vehicle goes up the temperature of temperature control box, provides more comfortable practical function for the user.
The vehicle-mounted thermostat control system in the embodiment of the present application is explained in detail below.
The embodiment of the application provides an on-board thermostatic control system, and as shown in fig. 1, the on-board thermostatic control system 100 includes a compressor 101, a condenser 102, a first evaporator 103, a second evaporator 104, a heat exchange pipeline 105, a thermostatic pipeline 106, and a thermostat 107.
Wherein an outlet of the compressor 101 is connected to an inlet of the condenser 102, a first outlet of the condenser 102 is connected to an inlet of the first evaporator 103, an outlet of the first evaporator 103 is connected to an inlet of the compressor 101, and the first evaporator 103 is used to provide cool air to an indoor space of the vehicle. A second outlet of the condenser 102 is connected to an inlet of the second evaporator 104, an outlet of the second evaporator 104 is connected to an inlet of the compressor 101, the second evaporator 104 contacts the heat exchange pipeline 105, two ends of the heat exchange pipeline 105 are respectively connected to two ends of the constant temperature pipeline 106, and the constant temperature pipeline 106 surrounds the constant temperature box 107 to cool the constant temperature box 107.
The compressor 101 is operated by a motor to discharge high-temperature and high-pressure gaseous refrigerant, and is used to push the refrigerant to flow in the vehicle thermostat control system. The condenser 102 is configured to dissipate heat and cool the high-temperature and high-pressure gaseous refrigerant discharged from the compressor 101, so that the high-temperature and high-pressure gaseous refrigerant is condensed into a high-pressure liquid refrigerant. The first evaporator 103 and the second evaporator 104 are used for exchanging heat between the high-pressure liquid refrigerant discharged from the condenser and the outside air, evaporating the liquid refrigerant into a gaseous state, and performing gasification and heat absorption to achieve a refrigeration effect.
Based on the on-board thermostat control system shown in fig. 1, a closed loop circuit is formed through closed-loop connections among the compressor 101, the condenser 102 and the first evaporator 103. A refrigerant (refrigerant) circulates in the closed loop circuit, and exchanges heat with the vehicle interior temperature. That is, this on-vehicle constant temperature control system can realize the cooling process to vehicle inner space.
In some embodiments, as shown in fig. 1, the on-board thermostat control system further includes a first valve 108. In this scenario, the connection relationship between the second outlet of the condenser 102 and the inlet of the second evaporator 104 may be: a second outlet of the condenser 102 is connected to an inlet of a first valve 108, and an outlet of the first valve 108 is connected to an inlet of the second evaporator 104. The first valve 108 is used to control the on/off or the flow rate of the refrigerant medium flowing through the second evaporator 104.
Through the above connection relationship, in the case that the first valve 108 controls the refrigerant medium (i.e. the high-pressure liquid refrigerant discharged from the condenser 102) to pass through, the second evaporator 104 can evaporate the high-pressure liquid refrigerant into a gaseous refrigerant, so as to achieve the refrigeration effect. The first valve 108 may be an electronic expansion valve.
In addition, the first valve 108 can also control the flow rate of the refrigerant medium, that is, the vehicle-mounted thermostatic control system can adjust the low-temperature of the heat exchange pipeline 105 connected with the second evaporator 104 by controlling the flow rate of the refrigerant medium, so as to adjust the temperature of the temperature control box 107.
In some embodiments, an aluminum plate is disposed between the second evaporator 104 and the heat exchange line 105, and since aluminum has a conductive function, the heat exchange line 105 can perform heat conduction with the gaseous refrigerant at the second evaporator 104, so that the second evaporator 104 can cool the fluid in the heat exchange line 105. Of course, any medium having a conducting function can be arranged between the second evaporator 104 and the heat exchange line 105.
Under the condition that the fluid in the heat exchange pipeline 105 is at a low temperature, the fluid in the constant temperature pipeline 106 can be cooled through the connection between the constant temperature pipeline 106 and the heat exchange pipeline 105. The fluid in the constant temperature pipeline 106 may be water or other liquid, which is not limited in this embodiment of the application.
In particular, the thermostatic line 106 comprises a first outlet and a second outlet. Under the condition that the first outlet of the thermostatic line 106 is connected with the inlet of the heat exchange line 105, and the outlet of the heat exchange line 105 is connected with the inlet of the thermostatic line 106, the fluid in the thermostatic line 106 can also achieve the effect of temperature reduction because the fluid in the heat exchange line 105 is at a low temperature.
Since the constant temperature pipe 106 surrounds the constant temperature tank 107, the constant temperature tank 107 can maintain a low temperature state in a state where the fluid in the constant temperature pipe 106 is at a low temperature. Therefore, the vehicle-mounted thermostatic control system in the embodiment of the present application can cool the oven 107 based on the connection between the heat exchange pipeline 105 and the first outlet of the thermostatic pipeline 106, so as to achieve the fresh-keeping effect on the articles on the oven 107.
For example, the first evaporator 103 in fig. 1 may be an HVAC206(Heating, Ventilation and Air Conditioning) system in fig. 2, and the HVAC206 may also provide cool Air to the indoor space of the vehicle. The second evaporator 104 and heat exchange line 105 of fig. 1 may be combined into heat exchanger 207 of fig. 2, which heat exchanger 207 also has the same function as the second evaporator 104 and heat exchange line 105.
In some embodiments, as shown in fig. 2, in the closed loop formed between the compressor 101, the condenser 102, and the HVAC206, the on-board thermostat control system may further include a radiator fan 201 located beside the condenser 102, a pressure sensor (P)202 located between the condenser 102 and the HVAC206, a mechanical expansion valve (T)203 connected to the HVAC206, an electronic expansion valve (V)204 located between the HVAC206 and the compressor 101, and a pressure/temperature sensor (P/T) 205.
The heat radiation fan 201 is used to radiate heat emitted by the condenser 102 when the gaseous refrigerant is condensed into a liquid state. Pressure sensor 202 is used to detect condenser 102 pressure. The mechanical expansion valve 203 and the electronic expansion valve 204 are used to control the flow rate of the refrigerant. The mechanical expansion valve 203 increases or decreases the refrigerant flow rate by sensing the degree of superheat at the outlet of the first evaporator 103(HVAC 206) and opening the expansion valve to a larger or smaller value. The electronic expansion valve 204 controls the flow rate of the refrigerant in response to a control command from the controller, wherein a preset program in the control command may be a program written by a worker according to a requirement. The pressure/temperature sensor 205 is used to detect and control the pressure and temperature of the high pressure line at the compressor 101 to provide a control signal for the compressor speed.
In addition, the on-board thermostat control system also includes a controller 1010. The controller 1010 is configured to control the fluid in the constant temperature line 106 to flow out of the first outlet in response to a cooling command.
Wherein, this cooling instruction needs to carry out cooling treatment to temperature control box 107, optionally, can carry the temperature value that needs to reduce in this cooling instruction.
Specifically, the controller may be coupled to the first valve 108. Upon receiving the temperature reduction command, the controller 1010 may control the refrigerant medium to pass through the second evaporator 104 based on the first valve 108, and may control the flow rate of the refrigerant medium passing through the first valve 108, so as to reduce the temperature of the fluid in the heat exchange pipeline 105 through heat conduction. The controller 1010 is operated to control the fluid in the constant temperature pipeline 106 to flow out through the first outlet and connect with the heat exchange pipeline 105, so as to achieve the effect of cooling the constant temperature pipeline 106. Eventually to achieve a cooling treatment of the oven 107 surrounded by the thermostatic line 106.
The connection between the controller 1010 and the first valve 108 may be an electrical connection, or other connection, which is not limited in this embodiment.
And upon receiving a heating command, the controller 1010 may control the refrigerant medium not to pass through the second evaporator 104 based on the first valve 108. The operation of heating the temperature control box 107 will be explained later.
Optionally, the on-board thermostat control system further comprises a make-up fluid tank (G) 1011. In this scenario, the connection relationship between the two ends of the heat exchange pipeline 105 and the two ends of the constant temperature pipeline 106 may be: an outlet of the heat exchange pipeline 105 is connected with an inlet of the liquid supplementing tank 1011, an outlet of the liquid supplementing tank 1011 is connected with an inlet of the constant temperature pipeline 106, and a first outlet of the constant temperature pipeline 106 is connected with an inlet of the heat exchange pipeline 105.
The fluid replenishing tank 1011 is used for replenishing enough fluid for the constant temperature pipeline 106 to perform cooling operation. The liquid in the fluid infusion tank 1011 may be water, or may be other liquids, which is not limited in the embodiments of the present application.
Optionally, the on-board thermostat control system further comprises a pump (B) 1012. In this scenario, the connection relationship between the two ends of the heat exchange pipeline 105 and the two ends of the constant temperature pipeline 106 may be: the outlet of the heat exchange line 105 is connected to the inlet of the pump 1012, the outlet of the pump 1012 is connected to the inlet of the thermostatic line 106, and the first outlet of the thermostatic line 106 is connected to the inlet of the heat exchange line 105.
Wherein the pump 1012 is used to control the transfer of fluid in the thermostatic line 106.
Optionally, as shown in fig. 2, the on-board thermostat control system may further include a fluid replacement tank 1011 and a pump 1012. In this scenario, the connection relationship between the two ends of the heat exchange pipeline 105 and the two ends of the constant temperature pipeline 106 may be as follows: the outlet of the heat exchange pipeline 105 is connected with the inlet of the liquid supplementing tank 1011, the outlet of the liquid supplementing tank 1011 is connected with the inlet of the pump 1012, the outlet of the pump 1012 is connected with the inlet of the constant temperature pipeline 106, and the first outlet of the constant temperature pipeline 106 is connected with the inlet of the heat exchange pipeline 105.
The fluid replenishment tank 1011 is used to replenish the constant temperature pipe 106 with sufficient fluid to ensure that there is sufficient fluid at the inlet of the pump 1012 to participate in the cooling operation.
Exemplarily, based on the vehicle-mounted thermostatic control system shown in fig. 2, the working principle of cooling the temperature control box is as follows: the on-board thermostat control system provides cool air to an indoor space of a vehicle based on a closed loop formed between a compressor 101, a condenser 102, and a first evaporator 103. And divides the refrigerant medium exiting the first outlet of the condenser 102 into two streams. One of the refrigerant mediums enters the second evaporator 104 and exchanges heat with the heat exchange pipeline 105 (i.e., a heat exchanger), so as to reduce the temperature of the fluid flowing through the inside of the heat exchanger. And after exchanging heat in the heat exchanger, the heat passes through the electronic expansion valve 204 and the pressure/temperature sensor 205 to form another closed loop, and the pressure and the temperature of the high-pressure pipeline at the compressor 101 are controlled. The other path of refrigerant medium enters the second evaporator 104 and the heat exchange pipeline 105 (i.e., a heat exchanger) for heat exchange, and then is connected with the constant temperature pipeline 106, so as to achieve the effect of cooling the thermostat 107 surrounded by the constant temperature pipeline 106.
The above processes are all detailed operations for describing a cooling process for a vehicle or for a temperature control box on the vehicle. The vehicle-mounted constant temperature control system can also realize heating treatment on the temperature control box.
In the scenario of performing the heating process on the temperature control box, as shown in fig. 3, the vehicle-mounted thermostat control system further includes a heating pipeline 109. Wherein the second outlet of the thermostatic line 106 is connected to the inlet of the heating line 109 and the outlet of the heating line 109 is connected to the inlet of the thermostatic line 106.
Alternatively, a PTC (Positive Temperature Coefficient) heater may be disposed in the heating line 109, and a heating process of the fluid in the heating line 109 may be performed by the PTC heater.
In some embodiments, the on-board thermostat control system also includes a controller 1010. The controller 1010 is also configured to control the fluid in the thermostatic line 106 to flow out of the second outlet in response to a heating command.
The heating instruction indicates that the temperature control box 107 needs to be heated, and optionally, the heating instruction may carry a temperature value to be heated.
Specifically, upon receiving a heating command, the controller 1010 may control the refrigerant medium not to pass through the second evaporator 104 based on the first valve 108. As such, the heating line 109 may control the PTC heater to heat the fluid in the heating line 109 based on the temperature value carried in the controller 1010 that requires heating. In this way, after the thermostatic line 106 performs heat transfer with the heating line 109, the controller 1010 is operated to control the fluid in the thermostatic line 106 to flow out through the second outlet, so as to achieve the effect of heating the oven 107 surrounded by the thermostatic line 106, and achieve the effect of keeping warm for the articles on the oven 107.
Optionally, the on-board thermostat control system further comprises a fluid replacement tank 1011. In this scenario, the connection relationship between the two ends of the heating pipeline 109 and the two ends of the constant temperature pipeline 106 may be: an outlet of the heating pipeline 109 is connected to an inlet of the fluid infusion tank 1011, an outlet of the fluid infusion tank 1011 is connected to an inlet of the constant temperature pipeline 106, and a second outlet of the constant temperature pipeline 106 is connected to an inlet of the heating pipeline 109.
The fluid replenishing tank 1011 is used for replenishing the constant temperature pipeline 106 with enough fluid to perform heating operation.
Optionally, the on-board thermostat control system further comprises a pump 1012. In this scenario, the connection relationship between the two ends of the heating pipeline 109 and the two ends of the constant temperature pipeline 106 may be: the outlet of the heating line 109 is connected to the inlet of the pump 1012, the outlet of the pump 1012 is connected to the inlet of the thermostatic line 106, and the second outlet of the thermostatic line 106 is connected to the inlet of the heating line 109.
