Detailed Description

In order to further describe the technical means and effects adopted by the invention to achieve the preset aim, the following detailed description is given below of the specific implementation, structure, characteristics and effects according to the invention with reference to the attached drawings and the preferred embodiments.

The present invention provides an integrated refrigerating method for a refrigerator and a cockpit, as shown in fig. 1, the integrated refrigerating method for the refrigerator and the cockpit comprises:

s1: acquiring a refrigeration instruction, and judging the refrigeration type of a user based on the refrigeration instruction; based on the refrigeration type, controlling the states of the refrigerant three-way valve and the refrigerant stop valve; controlling the operation states of the condenser assembly, the cargo box evaporator and the cockpit evaporator and controlling the operation state of the air conditioner compressor;

s2: acquiring temperature values and frost conditions of the cockpit and the refrigerator, and controlling the air conditioner compressor to be closed and controlling the condenser assembly, the container evaporator and the cockpit evaporator to be closed when the temperature values and/or preset frost-free conditions in the cockpit and the refrigerator meet the refrigerating requirements of users; and controlling the refrigerant three-way valve and the refrigerant stop valve to reset to the state before refrigeration.

The refrigerating instruction can be obtained by touching or pressing a refrigerating button at the vehicle end or a touch screen of a large screen at the vehicle end, and the corresponding refrigerating instruction is generated by the system. Or the refrigerating instruction can be generated by a voice control system and a gesture control system of the vehicle-mounted intelligent terminal or a temperature sensor control system of the vehicle end based on the environmental information condition of the vehicle end and transmitted to the integrated refrigerating control system. For example, when a user presses a button in the vehicle, the refrigerating system is started through the large-screen selection at the vehicle end, the refrigerating system is started through the voice control system, or the refrigerating system is started through the gesture control system through a preset gesture. In addition, the temperature value and the preset frost condition detected by the sensors arranged in the cockpit, the cargo box and the cargo warehouse at the vehicle end can be used for automatically controlling the air conditioner of the cockpit to refrigerate and cool when the preset temperature condition is met, for example, when the cockpit is someone and the air temperature reaches 40 ℃; when the temperature value of the container is higher than 12 ℃ based on the type of the refrigerated vehicle, automatically controlling the container evaporator to refrigerate and cool; if the temperature value of the container is lower than 0 ℃ and frost generated in the container reaches a preset defrosting condition, the container evaporator is automatically controlled to start to operate, and defrosting operation is performed. When the frost in the warehouse does not meet the preset defrosting conditions, the container evaporator is automatically controlled to stop defrosting operation, and the container is controlled to be cooled and refrigerated. Or, when the container is subjected to refrigeration control operation, the defrosting operation of the container is simultaneously carried out until the vehicle meets the preset temperature condition and the frost-free condition, and the operation of closing the condenser assembly, the container evaporator and the cockpit evaporator is controlled; and controlling the air conditioner compressor to be closed, and controlling the refrigerant three-way valve and the refrigerant stop valve to reset to the state before refrigeration. The refrigerant three-way valve and the refrigerant stop valve are reset to a state before refrigeration and a default initial value range before refrigeration, at the moment, the integrated refrigeration system is stopped, and the integrated refrigeration system is withdrawn after power is off. The preset defrosting conditions may include a preset time period, a time period within a preset temperature range, and a preset condition based on a frost morphology feature (such as a frost thickness or a frost image identification), or the preset defrosting conditions may be determined to be satisfied when the compressor performance data is within the preset range by inputting the environmental temperature and humidity data, the evaporator temperature data, and the compressor performance data as input parameters through fuzzy adaptive defrosting without establishing an accurate model, and by fuzzy processing the environmental temperature and humidity data, the evaporator temperature data, and the compressor performance data. The invention can also adopt a defrosting control method based on an intelligent algorithm, a prediction algorithm of defrosting and frosting of a refrigerating system based on a neural network is adopted, a neural network prediction model of a preset algorithm is established by inputting parameters to the neural network, a defrosting starting point is judged, automatic control optimization of a defrosting process is realized, and the neural network prediction model can establish a correlation between variables only by training acquired related defrosting process data. If a genetic algorithm and a BP neural network which are improved on a finite element model are adopted to predict the frosting quantity and the refrigerating capacity of the fin heat exchanger, a frosting quantity prediction and defrosting duration model based on the BP algorithm is established through given defrosting parameters, and defrosting control is carried out based on the model, so that the timeliness and the accuracy of defrosting in a warehouse are ensured.

For example, the refrigerant shut-off valve may be used to regulate and control the flow of refrigerant within the cockpit evaporator and condenser assembly, adjusting the flow rate and supply of refrigerant according to any one of the conditions of the cooling rate, the cooling type, etc. The pressure conditions among the cabin evaporator, the condenser assembly and the cargo box evaporator are controlled by the refrigerant stop valve, and the pressure conditions among the cabin evaporator, the condenser assembly and the cargo box evaporator are regulated by controlling the flow of the refrigerant, so that overheat during refrigeration is eliminated, and the temperatures of the cabin evaporator, the condenser assembly and the cargo box evaporator are changed. In this embodiment, the control device is mainly used for controlling the pressure condition of the cabin evaporator. If the refrigerant stop valve can also be automatically closed when the cockpit evaporator, the condenser assembly and the container evaporator fail, and then opened through manual operation, so as to protect the normal operation of the cockpit evaporator and the condenser assembly, and detailed description is omitted here.

Table one: control meter for control function of electric control unit

For example, as shown in table one, when the temperature of the cabin currently collected by the sensor is higher than 40 ℃, the temperature of the cargo tank is higher than a refrigerating preset temperature range of 0 ℃ and the cargo tank is in a frostless state, at this time, the electronic control unit obtains the temperature data of the cabin, the cargo tank and the frosting state data of the cargo tank to generate a refrigeration instruction, determines that the vehicle end of the user is in refrigeration type two based on the refrigeration instruction, and sequentially and respectively controls the refrigerant three-way valve b 203 to be communicated with the refrigerant three-way valve b 202, the refrigerant three-way valve a 302 to be communicated with the refrigerant three-way valve a 301, the refrigerant three-way valve c 1102 to be communicated with the refrigerant three-way valve c 1101, and controls the refrigerant stop valve 7 to be in an open state, and the connection direction and the conduction direction of the one-way valve 12 are from the refrigerant three-way valve c 1101 to the gas-liquid separator 14. The electronic control unit controls the refrigerant stop valve 7 and the refrigerant stop thermal expansion valve 9 to be in a conducting state, controls and adjusts the preset refrigerant stop valve 7 and the evaporator pressure regulating valve 13 to be in a preset cab refrigerating threshold range respectively, and controls and adjusts the refrigerant stop thermal expansion valve 9 and the container evaporator 10 to be in a refrigerating type two state respectively. The electronic control unit sequentially controls and opens the cargo box evaporator 10, opens the cockpit air conditioning system 8, opens the condenser assembly 4, controls and adjusts the pressure threshold value of the condenser assembly pressure sensor 5 to be in the preset threshold value range of cockpit refrigeration and cargo box refrigeration, further sequentially controls and adjusts the pressure threshold value of the preset evaporator pressure regulating valve 13 to be in the preset refrigeration threshold value range of cockpit refrigeration and cargo box refrigeration, finally starts the air conditioning compressor 1 to an operating state, and can adjust the operating speed of the air conditioning compressor 1, under the state of keeping the stable operation of the system, so as to further adjust the refrigeration efficiency, and further slowly control and adjust the specific change conditions of cockpit and/or cargo box rapid refrigeration, slow refrigeration and refrigeration maintenance as required.

For example, when the temperature of the cabin currently collected by the sensor is higher than 40 ℃, the temperature of the cargo tank is lower than a refrigerating preset temperature range of 0 ℃, and the cargo tank is in a frosting to-be-removed state, at this time, the electronic control unit acquires temperature data of the cabin, the cargo tank and a refrigerating defrosting instruction generated by frosting state data of the cargo tank, judges that the vehicle end of a user is in a refrigerating type III based on the refrigerating defrosting instruction, and sequentially and respectively controls the refrigerant three-way valve b port III 203 to be communicated with the refrigerant three-way valve b port I201, controls the refrigerant stop thermal expansion valve 9 to be in a cut-off state through the electronic control unit, and controls the refrigerant three-way valve c port II 1102 to be communicated with the refrigerant three-way valve c port III 1103 and the refrigerant three-way valve a port I301 to be communicated with the refrigerant three-way valve a port I301; the electric control unit is used for controlling the refrigerant stop valve 7 to be in a conducting state, and the electric control unit is used for respectively controlling the first pressure sensor 6 at the passage port of the refrigerant three-way valve b and the condenser assembly pressure sensor 5 to be in a preset refrigerating pressure range of cabin refrigeration and cabin defrosting, namely respectively controlling the first pressure sensor 6 at the passage port of the refrigerant three-way valve b and the condenser assembly pressure sensor 5 to be in a preset threshold state corresponding to the third refrigerating type of the cargo box refrigeration and the cabin refrigeration.

The electronic control unit sequentially controls and opens the cargo box evaporator 10, opens the condenser assembly 4, opens the cockpit air conditioning system 8, and respectively controls and adjusts the pressure threshold value of the pressure sensor 6 of the channel port of the refrigerant three-way valve b and the pressure threshold value of the pressure sensor 5 of the condenser assembly to be in the preset threshold value range of cockpit refrigeration and warehouse defrosting, further sequentially controls and adjusts the pressure threshold value of the preset evaporator pressure regulating valve 13 to be in the preset refrigerating threshold value range of cockpit refrigeration and warehouse refrigeration, finally starts the air conditioning compressor 1 to an operating state, adjusts the operating speed of the air conditioning compressor 1, and further adjusts the refrigerating efficiency under the state of maintaining the stable operation of the system so as to further slowly control and adjust the cockpit refrigeration and the warehouse defrosting speed according to requirements, such as specific control and adjustment changes of rapid speed, slow speed, maintenance and the like.

For example, when the temperature of the cabin currently collected by the sensor is in a normal proper temperature range, such as 26 ℃, the temperature of the cargo box is lower than a refrigerating preset temperature range of 0 ℃, and the cargo box is in a frostless state, the electronic control unit obtains the temperature data of the cabin, the cargo box and the frosting state data of the cargo box to generate a refrigeration instruction, determines that the vehicle end of the user is in a refrigeration type IV based on the refrigeration instruction, and the electronic control unit is based on a control instruction of the refrigeration type IV. Firstly, the air-conditioning compressor 1, the condenser assembly 4, the container evaporator and the cockpit air conditioning system are controlled by the electric control unit to be closed in sequence, and then the refrigerant three-way valve a3, the refrigerant three-way valve b2, the refrigerant three-way valve c11, the refrigerant stop valve 7 and the refrigerant stop thermal expansion valve 9 are controlled by the electric control unit to be in a default initial value state. The default initial value can keep the refrigerant stop valve 7 and the refrigerant stop thermal expansion valve 9 in a stop state, and the evaporator pressure regulating valve 13 is in an adjustable initial value state. In addition, the blower can be started to slowly suck low-temperature air in the container into the high-temperature cockpit for refrigeration, so that the temperature of the container and the cockpit can be kept within a preset normal temperature range for a longer time, and the air conditioner compressor 1 is prevented from being frequently started and/or closed when the temperature of the container and the cockpit is abnormal.

For example, when the temperature of the cabin currently collected by the sensor is lower than 26 ℃, the temperature in the container is greater than a non-refrigeration preset temperature range of 0 ℃, and the container is in a frostless state, the electronic control unit acquires the temperature data of the cabin, the container and the container, and the frosting state data of the container at the moment to generate a refrigeration instruction, determines that the vehicle end of the user is in a refrigeration type five based on the refrigeration instruction, and sequentially controls the refrigerant three-way valve b channel port three 203 to be communicated with the refrigerant three-way valve b channel port two 202, the refrigerant three-way valve a channel port two 302 to be communicated with the refrigerant three-way valve a channel port one 301, the refrigerant three-way valve c channel port two 1102 to be communicated with the refrigerant three-way valve c channel port one 1101, the electronic control unit controls the refrigerant stop valve 7 to be in a closed stop state, the refrigerant stop thermal expansion valve (9) to be in a conducting state, the conducting direction of the one-way valve 12 is from the refrigerant three-way valve c channel port 1101 to the gas-liquid separator 14, and the electronic control unit controls to respectively regulate the refrigerant stop thermal expansion valve 9 and the container evaporator 10 to be in a running state of the type five. The electronic control unit sequentially controls the cargo box evaporator 10 to be opened, the condenser assembly 4 to be opened, and controls and adjusts the pressure threshold value of the condenser assembly pressure sensor 5 to be in the preset threshold value range of cargo box refrigeration, further sequentially controls and opens the air conditioner compressor 1 to be in an operating state, and can adjust the operating speed of the air conditioner compressor 1. The refrigerating efficiency can be further regulated when the operation of the integrated refrigeration is kept in a stable operation state, so that the specific control changes and the operation conditions of the rapid refrigeration, the slow refrigeration and the refrigeration maintenance of the container can be further controlled and regulated slowly according to the requirement.

For example, when the temperature of the cabin currently collected by the sensor is lower than 26 ℃, the temperature in the container is greater than a non-refrigeration preset temperature range of 0 ℃, and the container is in a frosted state, at this time, the electronic control unit acquires the temperature data of the cabin, the container and the container, and the frosted state data of the container to generate a refrigeration command, determines that the vehicle end of the user is in refrigeration type six based on the refrigeration command, and sequentially and respectively controls the refrigerant three-way valve b channel port three 203 to be communicated with the refrigerant three-way valve b channel port one 201, the refrigerant three-way valve c channel port two 1102 to be communicated with the refrigerant three-way valve c channel port 1101, the electronic control unit controls the refrigerant stop valve 7 to be in a closed stop state, the refrigerant stop thermal expansion valve 9 to be in a stop state, the conduction direction of the one-way valve 12 is from the refrigerant three-way valve c channel port 1101 to the gas-liquid separator 14, and the electronic control unit respectively controls and adjusts the refrigerant stop thermal expansion valve 9 and the container evaporator 10 to be in operation state of refrigeration type six. The electronic control unit sequentially controls and turns on the cargo box evaporator 10, and further sequentially controls and turns on the air conditioner compressor 1 to defrost, and keeps the operation of the above-mentioned integrated refrigeration in a stable operation state, and can further adjust the operation speed of the air conditioner compressor 1 for defrosting, so as to further adjust the refrigeration efficiency, and further slowly control and adjust the specific control changes and operation conditions of the rapid defrosting, the slow defrosting, and the defrosting maintenance (or the defrosting with a preset period duration) of the cargo box as required.
