Referring to fig. 1 to 8, a heat management system for an energy storage container is shown, in which a refrigerant circuit includes a compressor 1, a fluorine pump 13, a four-way valve 2, a condenser 3, an expansion valve 4, a second stop valve 7, a battery cooler 8, a first stop valve 5, an evaporator 6, an electronic fan 9, a gas-liquid separator 10, a third stop valve 11, and a fourth stop valve 12, and pipelines of the refrigerant circuit are connected to each component. The cooling water circuit components are a water pump 15, an energy storage battery pack 16, a flow-adjustable three-way valve 17 with two branches 171 and 172, a high-pressure PTC14 and a low-temperature radiator 18, and a plurality of cooling water circuit pipelines are connected with each component. The coolant loop and the cooling water loop are associated by a battery cooler 8 for heat transfer and thermal management. The low temperature radiator 18, the condenser 3, the evaporator 6 and the electronic fan 9 are sealed by an air duct and controllable air doors, and the functions of air suction or air blowing inside or outside the container can be realized by controlling the operation and combination of different air doors. The system uses environment-friendly and safe refrigerants such as R134a, R410A, R22 and the like. The whole system can be integrated into a heat management cabinet with a compact structure which can be embedded in an energy storage container, the output interface of the container is only an inlet and outlet pipe of a water path and a control panel with control and display functions, and the external environment is mainly a window for exchanging air and heat with a heat exchanger.
In the charging, discharging and electric power storage heat preservation processes when the energy storage container is connected with a power grid, different heat dissipation or heat preservation requirements are met for batteries, and the operation working conditions of the heat management system of the energy storage container are complex due to the difference of environmental temperatures.
And in the first refrigeration mode, when the external environment temperature is lower than the temperature range required by the work of the battery and the temperature difference meet certain conditions, the refrigerant loop is closed, and the low-energy-consumption cooling water loop is opened. As shown in fig. 2, the operation logic of the cooling water loop is that low-temperature cooling water is pumped into the energy storage battery 16 by the water pump 15, the antifreeze solution after absorbing the heat of the energy storage battery pack enters the low-temperature radiator 18 by the branch 171 of the three-way valve 17, and the radiator discharges the low-temperature antifreeze solution after running through the electronic fan 9 and convecting with air, and then circulates into the water pump 15; the working mode reduces the working energy consumption of the refrigerant loop, is environment-friendly and energy-saving, and prolongs the service life of the refrigerant system.
In the second refrigeration mode, when the external environment temperature is close to the temperature range required by the battery work and the temperature difference meet certain conditions, the refrigeration mode 1 is started, the water flow or the air volume is simply increased, the heat dissipation effect of the low-temperature radiator is not ideal, and the refrigerant fluorine pump refrigeration mode is started at the moment. In this case, the refrigerant in the refrigerant loop is pumped into the four-way valve 2 by the running fluorine pump 13, is regulated to enter the condenser 3 to form a medium-temperature high-pressure liquid, is circulated to enter the expansion valve to expand to form a low-temperature low-pressure liquid, the refrigerant entering the battery cooler 8 is subjected to heat exchange to form a low-temperature low-pressure gas, is regulated by the four-way valve 2 to enter the gas-liquid separator 10, and the refrigerant entering the gas-liquid separator is circulated to enter the fluorine pump 13 by the opened third stop valve 11. In the water circuit, the high-temperature antifreeze solution flowing out of the energy storage battery module 16 is adjusted by the three-way valve 17 to enter the battery cooler 8 to be cooled into low-temperature antifreeze solution, and then circularly flows into the PTC14 in the non-operating state, and then circularly enters the energy storage battery pack 16 by the water pump to cool the battery pack, as shown in detail in fig. 3. The energy-saving effect of the mode is obvious compared with the running working condition of the electric compressor with low rotating speed, and meanwhile, the compressor is prevented from being started and stopped frequently, so that the service life of the compressor is prolonged.
And in the third refrigeration mode, when the external environment temperature is lower than the temperature range required by the battery work and the temperature difference meets a certain condition, the first refrigeration mode and the second refrigeration mode, namely the low-temperature heat dissipation cycle and the fluorine pump refrigeration cycle, are started simultaneously. The operation logic of the cooling water loop is that low-temperature cooling water is pumped into the energy storage battery module 16 by the water pump 15, the antifreeze heated by absorbed heat is adjusted by the three-way valve 17 and simultaneously enters the low-temperature radiator 18 and the battery cooler 8 for cooling, and the cooled low-temperature antifreeze is collected and circulated into the water pump 15. The refrigerant loop operation line is that the refrigerant is pumped into the four-way valve 2 by the operating fluorine pump 13, is regulated to enter the condenser 3 for heat convection and cooling with wind, then circularly enters the expansion valve 4 for expansion to form low-temperature low-pressure liquid, the refrigerant entering the battery cooler 8 is subjected to heat exchange to form low-temperature low-pressure gas, the low-temperature low-pressure gas is regulated by the four-way valve 2 to enter the gas-liquid separator 10, and the refrigerant entering the gas-liquid separator 10 is circulated into the fluorine pump 13 through the opened third stop valve 11, as shown in detail in fig. 4.
And the fourth refrigeration mode is used for starting the refrigeration cycle when the external environment temperature is higher and the refrigeration capacity demand of the battery module cannot be met by starting the third refrigeration mode. In the water loop circulating system, antifreeze which flows out of the energy storage battery module 16 and absorbs heat to raise temperature is adjusted by a three-way valve 17 to enter the battery cooler 8 to be cooled into low-temperature antifreeze, and flows into the high-voltage PTC14 which is not started in a circulating mode, and then flows into the energy storage battery pack 16 in a circulating mode through a water pump 15 to start cooling the energy storage battery pack 16. The refrigerant in the refrigerant loop is pressurized by the running electric compressor 1 to form a high-temperature and high-pressure refrigerant, then circularly enters the four-way valve 2 to be adjusted and enters the condenser 3 to form a medium-temperature and high-pressure liquid, then enters the expansion valve 4 to be expanded to form a low-temperature and low-pressure liquid, the refrigerant entering the battery cooler 8 absorbs heat to form a low-temperature and low-pressure gas, the low-temperature and low-pressure gas is adjusted by the four-way valve 2 to enter the gas-liquid separator 10, and the refrigerant entering the gas-liquid separator 10 is circularly entered into the electric compressor 1 by the opened stop valve 12, which is shown in detail in fig. 5.
The first heating mode is that when the battery pack in the energy storage container needs to be heated to keep a reasonable working temperature range, the four-way valve 2 loop is adjusted to start the working condition mode of the refrigerant loop heat pump. The operation principle diagram is shown in fig. 6. The refrigerant loop operation flow is that the refrigerant is pressurized by the running electric compressor 1 to form a high-temperature high-pressure gaseous refrigerant, then circularly enters the four-way valve 2 to be regulated, enters the battery cooler 8 to be cooled to form medium-temperature high-pressure liquid, then enters the expansion valve 4 to form low-temperature low-pressure liquid, enters the condenser 3 to form low-temperature low-pressure gas through air convection heat absorption, circularly enters the gas-liquid separator 10 through the four-way valve 2 to be regulated, and the refrigerant entering the gas-liquid separator 10 is circularly sucked into the electric compressor 1 through the opened stop valve 12. In the water loop circulation, the antifreeze solution flowing into the battery cooler 8 at a low temperature absorbs heat removed by the refrigerant to form high-temperature antifreeze solution, the antifreeze solution flows into the water pump 15 through the high-pressure PTC14 which is not started, is pressurized and then pumped into the energy storage battery pack 16, and the antifreeze solution after heat release circulates through the three-way valve 17 and is regulated to flow into the battery cooler 8 again through the branch 172 to form complete circulation.
A second heating mode, where the high voltage PTC14 is enabled during the first heating mode cycle when the ambient temperature is low while the energy storage container battery pack requires more heat to ensure a reasonable temperature range for the battery. The high-voltage PTC14 can adjust the heating power according to the grade of the battery heat preservation and temperature rise requirements to meet different requirements of rapid temperature rise and heat preservation, and the operation principle diagram is shown in figure 7.
And in the efficient dehumidification mode, when the air humidity is higher, the air needs to be dehumidified and treated due to harsh working environment requirements of a plurality of electrical elements in the energy storage container. When the control system detects the input signal, the dehumidification mode of the refrigerant loop is started. The operation principle diagram is shown in fig. 8, the refrigerant is pressurized by the started electric compressor 1 to form a high-temperature and high-pressure refrigerant, then the refrigerant circularly enters the four-way valve 2 to be regulated and enters the condenser 3 to form medium-temperature and high-pressure liquid, then enters the expansion valve 4 to be expanded to form low-temperature and low-pressure liquid, the refrigerant entering the evaporator 6 through the first stop valve 5 absorbs heat to form low-temperature and low-pressure gas, the gas is regulated by the four-way valve 2 to enter the gas-liquid separator 10, and the refrigerant entering the gas-liquid separator 10 is circularly entered into the electric compressor 1 through the opened stop valve 12 to form complete refrigerant circulation. Meanwhile, when the system operates, the air in the container is pressurized by the fan, then passes through the evaporator 6 and the condenser 3 in sequence and returns to the interior of the container through the control air door, when the air passes through the evaporator 6, the dew point temperature is reduced due to the reduction of the temperature of the air, and moisture separated out from the air passing through the evaporator 6 is discharged to the exterior of the container through the pipeline. The system is repeatedly operated until the humidity of the internal air meets a certain standard and then the mode is closed.
