Specifically, the extracted heat exchange substance may be injected into a heat exchange assembly disposed in the refrigerator unit of the refrigerator car in a circulating water manner, where the circulating water manner means that water flows in a circulating pipeline, that is, the extracted heat exchange substance is injected into the heat exchange assembly for heat exchange and then returns to the preset water storage assembly. The heat exchange assemblies are arranged around the parts of the refrigerator car refrigerating unit which need to optimize the working environment, for example, a part of the heat exchange assemblies can be arranged around the compressor, a part of the heat exchange assemblies can be arranged at the bottom of the controller, and a part of the heat exchange assemblies can be arranged around the evaporator. When circulating water flows through the heat exchange assembly, the circulating water exchanges heat with the refrigerating unit of the refrigerator car, and the heat exchange comprises that when the environment is high, the circulating water absorbs heat released by the normal work of the refrigerating unit of the refrigerator car so as to reduce the temperature of the working environment around the refrigerating unit of the refrigerator car and realize the optimization of the working environment; or when the environmental temperature is higher, the circulating water is heated and releases heat to the refrigerating unit of the refrigerator car so as to raise the temperature of the working environment around the refrigerating unit of the refrigerator car and realize the optimization of the working environment; or when the environmental humidity is great, further judge refrigerator car refrigerating unit internal unit and ambient temperature difference, when the difference between the two is greater than preset difference in temperature threshold value, show that the very big possibility of evaporimeter takes place to frost in the refrigerator car refrigerating unit, need change the frost operation to it, at this moment, release heat to the evaporator in the refrigerator car refrigerating unit after the circulating water heating to the defrosting of realization evaporimeter.

when the refrigerator is in a preset high-temperature environment according to the environmental parameter identification, the extracted heat exchange substance is injected into a first heat exchange assembly arranged in the refrigerator car refrigerating unit in a circulating water mode so as to reduce the temperature of a compressor in the refrigerator car refrigerating unit.
The preset high-temperature environment specifically means that the current environment temperature is higher than a preset high-temperature interval, and when the current environment temperature is higher than the preset high-temperature interval, the preset high-temperature environment belongs to the high-temperature environment. Generally, the high temperature range can be set to 43-45 ℃, that is, when the ambient temperature is higher than 43-45 ℃, the high temperature environment is determined. When present refrigerator car refrigerating unit is in under the high temperature environment, the high-speed operation of compressor releases a large amount of heats, and compressor ambient temperature can obviously be higher than ambient temperature further, and it can reach 90 ~ 100 ℃ of temperature, if the compressor is under this 90 ~ 100 ℃ of environment for a long time, it probably breaks down. In contrast, the optimization system injects water into a heat exchange assembly arranged in a refrigerating unit of the refrigerator car in a circulating water mode, and the temperature of the water is generally close to or lower than the ambient temperature; when the circulating water flows through the heat exchange assembly, a large amount of heat is absorbed, so that the temperature of the assembly including the compressor in the refrigerator car refrigerating unit is reduced, the cooling is realized, the compressor is prevented from being broken down under the high-temperature environment as much as possible, and the reliability of the refrigerator car refrigerating unit is improved. Further, the circulating water can only concentrate to flow through and set up in the heat exchange assemblies of compressor, concentrates and absorbs a large amount of heats in the compressor surrounding environment, and rapid cooling absorbs thermal circulating water and can flow back once more and predetermine water storage assembly, predetermine water storage assembly release heat, the cooling, then extract the circulation that realizes the cooling once more.
In one embodiment, injecting the extracted heat exchange material into a heat exchange assembly disposed in a refrigeration unit of a refrigerated vehicle to optimize an operating environment of the refrigeration unit comprises:
when the device is in the preset high-temperature environment according to the environment parameter identification, the extracted heat exchange material is injected into a second heat exchange assembly arranged in the refrigerator car refrigerating unit in a circulating water mode so as to reduce the temperature of a controller in the refrigerator car refrigerating unit.
When present refrigerator car refrigerating unit is in under the high temperature environment, a large amount of heats of controller operation release, and compressor ambient temperature can obviously be higher than ambient temperature further, and it can reach 90 ℃ of temperature, if the heat does not discharge controller meeting IPM shutdown protection. In contrast, the optimization system injects water into a heat exchange assembly arranged in a refrigerating unit of the refrigerator car in a circulating water mode, and the temperature of the water is generally close to or lower than the ambient temperature; when the circulating water flows through the heat exchange assembly, a large amount of heat is absorbed, so that the temperature of the assembly including the controller in the refrigerator car refrigerating unit is reduced, the cooling is realized, the shutdown of the controller in a high-temperature environment is avoided as much as possible, and the reliability of the refrigerator car refrigerating unit is improved. Further, the circulating water can only concentrate to flow through and set up in controller bottom or heat exchange assemblies all around, concentrates and absorbs a large amount of heats in the controller surrounding environment, and rapid cooling absorbs thermal circulating water and can flow back once more and predetermine water storage assembly, predetermine water storage assembly release heat, the cooling, then extract the circulation that realizes the cooling once more.

The preset low-temperature environment specifically refers to a low-temperature range with the environment temperature lower than the preset low-temperature range, the low-temperature range can be set to be-15-5 ℃ or-15-20 ℃, and if the current environment temperature is identified to be lower than the low-temperature range according to the environment parameters, the current environment is judged to be in the preset low-temperature environment. Under the low temperature environment, a large amount of liquid heat exchange substances exist on the low-pressure side of the refrigerator unit of the refrigerator car after being placed for a long time, and the liquid heat exchange substances enter the compressor when the refrigerator unit is directly started, so that the compressor is damaged and cannot be started according to normal running. In contrast, the extracted heat exchange material is heated in a circulating water mode and then is injected into a heat exchange assembly arranged on a refrigerating unit of the refrigerator car, and the circulating water can form high-temperature water vapor after being heated; when high-temperature water vapor flows through the heat exchange assembly, a large amount of heat is released, so that the temperature of the assembly including the compressor in the refrigerator unit of the refrigerator car is increased, the temperature rise is realized, the compressor can be normally started, and the reliability of the refrigerator unit of the refrigerator car is improved. Further, the circulating water can only concentrate the flow through and set up in compressor bottom or heat exchange assemblies all around, concentrates release heat to compressor, rapid heating up, and the circulating water of release heat can flow back once more and is predetermine water storage component, then extracts the circulation that realizes the intensification once more.

when the evaporator is in a preset low-temperature and high-humidity environment according to the environment parameter identification, the extracted heat exchange substance is injected into a third heat exchange assembly arranged in the refrigerator car refrigerating unit in a circulating water mode so as to defrost the evaporator in the refrigerator car refrigerating unit.
The preset low-temperature and high-humidity environment means that the current environment temperature is lower than a preset low-temperature range, the humidity is greater than a preset humidity threshold value, and the preset low-temperature range can be specifically-20-5 ℃; the preset humidity threshold value can be 60%, when the current environment temperature is lower than the low-temperature and the humidity is higher than the preset humidity threshold value according to the environment parameters, the current environment is judged to belong to the low-temperature and high-humidity environment, the evaporator in the refrigerator car refrigerating unit can be frosted in the environment, the evaporator can influence the normal work of the refrigerator car refrigerating unit after being frosted in a large area, and therefore the extracted heat exchange substance is heated in a circulating water mode and then injected into a heat exchange assembly arranged in the refrigerator car refrigerating unit, and the circulating water can form high-temperature water vapor after being heated; when high-temperature water vapor flows through the third heat exchange assembly, a large amount of heat is released to defrost the evaporator, and the reliability of the refrigerating unit of the refrigerator car is improved. Further, the circulating water can only concentrate the flow through and set up in the heat exchange assemblies all around of evaporimeter, concentrates release heat to evaporimeter, realizes quick defrosting, and the circulating water of release heat can flow back once more and predetermine water storage component, then extracts once more and realize the defrosting operation. Furthermore, when the external environment temperature is low, the heating defrosting mode is adopted, and if the external environment temperature is not low, the extracted heat exchange substance can be directly injected into the third heat exchange assembly in a circulating water mode to defrost the evaporator. If the external environment temperature is lower than the preset temperature threshold, judging that the external environment temperature is lower; the preset temperature threshold may be specifically 10 ℃.
In one embodiment, after the step of transferring the extracted heat exchange material to a heat exchange assembly disposed in a refrigerator car unit to optimize the operating environment of the refrigerator car unit, the method further comprises the steps of:
and when the working environment in the refrigerating unit of the refrigerator car is adjusted to the normal working environment, stopping injecting the circulating water.
When the working environment in the refrigerator car refrigerating unit is adjusted to the normal working environment, the refrigerator car refrigerating unit can normally work at the moment, the working environment is not needed to be optimized and adjusted any more, the optimization system stops injecting circulating water at the moment, and specifically, a water pump in the optimization system can be stopped from running.
It should be understood that, although the steps in the flowcharts are shown in sequence as indicated by the arrows, the steps are not necessarily performed in sequence as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise. Moreover, at least a part of the steps in each of the flowcharts described above may include multiple steps or multiple stages, which are not necessarily performed at the same time, but may be performed at different times, and the order of performing the steps or stages is not necessarily sequential, but may be performed alternately or alternately with other steps or at least a part of the steps or stages in other steps.

In order to further explain the technical principle and the technical effect of the working environment optimization system of the refrigerator car refrigerating unit in detail, the following will first briefly introduce the working principle of the refrigerator car refrigerating unit and the overall improvement concept of the basic working environment optimization system of the refrigerator car refrigerating unit.
As shown in figure 5, the refrigerating unit in the whole overhead unit is arranged in a carriage 5-3 and comprises a water storage tank 5-1, an outer fan (main water inlet) 5-2, an inner fan 5-4, an evaporator 5-5, electric heating 5-6, an inner machine air outlet 5-7 and a compressor module 5-8. Specifically, the actual use condition is divided into two parts, and 3 hoses are used for connection in the middle. Respectively a high-pressure pipe, a low-pressure pipe and a hot air pipe. The outdoor unit 5-9 is placed on the top of the vehicle compartment. The use working condition of the outdoor unit 5-9 is the external environment temperature, the use temperature of most regions in China is simulated, and the unit needs to meet the temperature fluctuation of-20 ℃ to 45 ℃. The working condition area is large, the pressure ratio of the relevant limit temperature to the reliability of the unit is large, the temperature is 45 ℃, the pressure of the compressor module 5-8 is large, the exhaust temperature of the compressor module 5-8 is too high, and the normal operation of the compressor module 5-8 is influenced. Meanwhile, the external environment temperature can influence the heat dissipation speed of the electric appliance box, the IPM can protect the shutdown, and components are easy to damage. Under the low-temperature working condition of-20 ℃, under the condition that the compressor module 5-8 is directly started after long-term stopping, a refrigerant enters the compressor module 5-8, and the unit cannot be normally started. The air duct of the condensing fan of the outdoor unit is a main water inlet of the whole unit, and the condensing air duct has a larger space for installing a water storage tank. Therefore, the core additional component water storage tank of the whole scheme is finally confirmed to be placed in the condensation air cavity of the outdoor unit. The water is transmitted to other heat exchangers and other components through a special water pipe for cooling or heating, and each flow path is opened or closed through a solenoid valve control switch and finally returns to the water storage tank to form a circulating system. The main components in the internal machine are an internal fan 5-4, electric heating 5-6, an evaporator 5-5 and related pipelines. The electric heaters 5 to 6 have not only the function of adjusting the temperature of the internal environment but also the function of heating the circulating water in an auxiliary manner in the present embodiment. In the use condition of the internal machine, the temperature fluctuation is required to be between 20 ℃ below zero and 30 ℃. Under the high-temperature working condition, no special working condition is processed in an important way. However, at the low temperature of-20 ℃ to 5 ℃, the evaporator 5-5 may be frosted, and the frosting affects the heat exchange efficiency of the evaporator 5-5, so that the refrigerating capacity is reduced. This special case is related to the humidity of the air inside the cabinet. The greater the humidity, the faster the rate of frost formation.
Rainwater stored from the outside is placed in an air duct of the condenser, a floating ball type water quantity tester is arranged in the air duct, the function of the floating ball type water quantity tester is to monitor the water storage quantity of the current unit, when the water quantity is insufficient, environment optimization is realized without adopting the scheme, and when the water quantity is sufficient, a circulating water system is started to carry out reliability. When the water storage speed is faster, a smaller heat exchange temperature difference can be used, and when the water storage speed is slower, a larger heat exchange temperature difference can be used. And a water pump is connected behind the container and used as the power of the whole circulating water system, and the on-off of the component directly controls the on-off of the whole system. After the pump, there are 4 branches, each of which is a case handling scheme. The specific 4 cases are shown in fig. 6.
In the first case, the outside temperature is high, the compressor operating speed is high, and the compressor discharge temperature is high, which may affect the operation of the compressor. In order to improve the compressor reliability under the high-temperature working condition, the scheme of the patent can be adopted for solving the problem. When the temperature collected by the compressor thermal bulb exceeds the set normal operation temperature, the water level in the water storage tank and the increasing speed of the water level are synchronously detected, a set value is given according to the water level and the increasing speed of the water level, the water pump body is opened to provide reasonable rotating speed, if the water level reaches a preset (certain) value, the water pump is opened, the branch electromagnetic valve is opened, other electromagnetic valves are closed, and circulating water directly enters the heat exchanger. The water temperature of the circulating water is roughly the same as the external environment temperature at present, meanwhile, the temperature of the compressor is different according to the actual situation under the working condition, but the temperature is basically 90-100 ℃, and the rotating speed of the water pump is provided to the controller through the temperature of the temperature sensing bulb, is calculated and adjusted, and then is supplied to the water pump. Meanwhile, the temperature of the compressor is cooled by the temperature of the circulating water. And closing the water pump and the electromagnetic valve until the temperature of the compressor is maintained at the normal operation temperature, so as to achieve the purpose of improving the reliability of the special condition.
In the second situation, when the external working condition is relatively low, for example, under the condition of-15 ℃ to-20 ℃, a large amount of liquid heat exchange substances exist on the low-pressure side of the unit after being placed for a long time, and the direct starting can cause the liquid heat exchange substances to enter the compressor, damage the compressor and cannot be started according to normal running. Under the low-temperature working condition, the processing scheme of the method is that the temperature is collected by the air-suction temperature sensing bulbs of all parts, the unit is judged to be in the low-temperature liquid-carrying starting working condition, and then the following actions are performed according to logic added by the controller. When the temperature collected by the compressor thermal bulb is lower than the set normal operation temperature, the shutdown state of the compressor is continued for a certain state. The water level and the water level increasing speed in the water storage tank are synchronously detected, a set value is given according to the water level and the water level increasing speed, the water pump body is opened to provide a reasonable rotating speed, the electromagnetic valve before electric heating is performed, if the water level reaches a preset (certain) value, the water pump is opened, the electromagnetic valve before the compressor is opened, and other electromagnetic valves are closed. The temperature of water in the container is the same as the temperature of an external environment, the temperature is-15 ℃ to-20 ℃, the water is heated by the water pump, the heated water can be regarded as steam of 150 ℃ in the electric heating heat exchanger, then the bottom of the compressor is heated, the final heating time is to turn on the compressor by closing the water pump and the electromagnetic valve according to the actual temperature of the temperature sensing bulb when the temperature is 0 ℃. The scheme can improve the reliability of the unit under the starting condition of low external environment temperature.
In the third situation, under the condition that the external environment temperature is higher, the controller generates a large amount of heat in a working chamber due to higher working conditions, the test can reach 90 ℃, and the IPM is shut down for protection if the heat is not discharged out of the controller. In order to improve the reliability under such conditions, the following solutions may be used. Under the condition of high external temperature, the heat can be dissipated through circulating water under the condition that the set value is 43-45 ℃ or even higher. The water temperature in the container is 43-45 ℃ of the external environment temperature, the temperature in the controller is 90 ℃, the water level in the water storage tank is synchronously detected, a set value is given according to the water level, and the water pump body is opened to provide reasonable rotating speed. If the water level reaches a preset (certain) value, the water pump and the electromagnetic valve of the heat exchanger at the bottom of the controller are started, the heat of the controller is taken away through circulating water, and the water pump and the electromagnetic valve are closed until the temperature of the controller is reduced to 65 ℃, so that the electric appliance box can keep relatively low temperature, and the running reliability of the unit is improved.
In the fourth situation, when the ambient temperature of the internal combustion engine reaches-20 ℃ to 5 ℃, the evaporator is frosted under the condition of high humidity, and under the working condition, the following scheme can be used. The water level in the water storage tank and the increasing speed of the water level are detected, a set value is given according to the water level and the increasing speed of the water level, and the water pump body is opened to provide reasonable rotating speed. And judging which electromagnetic valve is opened according to the temperature acquired under the actual condition. And if the external environment temperature is less than 10 ℃, opening an electromagnetic valve of the electric heating heat exchanger, and opening a defrosting electromagnetic valve inside the evaporator, wherein at the moment, the circulating water is heated by electric heating to carry out a defrosting mode. When the temperature is higher than 10 ℃, the bypass electromagnetic valve can be directly opened, so that the external circulating water is directly defrosted through the defrosting pipe in the evaporator, and the method can be directly carried out.
