Description

Technical Field

[0001] The present application relates to the field of energy storage technology, and in particular to an energy storage temperature control system and an energy storage system. Background Art

[0002] The current energy storage integrated machine (i.e., energy storage system, including PCS (energy storage inverter, Power Conversion System) and / or energy storage battery PACK and temperature control system), wherein the temperature control system includes: compressor, condenser, throttling device, evaporator, fan matching with the condenser (accelerating heat dissipation at the condenser), fan matching with the evaporator and corresponding connecting pipes; the throttling device includes an expansion valve, the compressor is connected to the condenser through a pipe, the condenser is connected to the throttling device through a pipe, the throttling device is connected to the evaporator through a pipe, the pipe is the flow channel of the refrigerant, and the refrigerant can be Freon. Among them, the evaporator is located in the energy storage integrated machine cabinet (hereinafter referred to as the cabinet), and the rest are located outside the cabinet. When the air conditioner is working, the cold air is blown into the cabinet through the evaporator under the action of the corresponding fan. The evaporator is the lowest temperature in the cabinet, so condensation will be generated in the evaporator and collected and discharged from the evaporator. However, when the air conditioner stops working, the compressor and the corresponding fan stop working. However, under the action of inertia, the high-temperature and high-pressure refrigerant generated by the compressor will pass through the condenser. At this time, the fan has stopped working and cannot help dissipate heat. The high-temperature and high-pressure gas-liquid mixed refrigerant passes through the throttling device and becomes a high-temperature, normal-pressure gas that flows through the evaporator, causing the temperature of the evaporator to rise rapidly. The condensation condensed on it evaporates into water vapor, which is diffused in the battery compartment and / or PCS compartment under the action of the fan matched with the battery and / or PCS, causing the humidity in the battery compartment and / or PCS compartment to rise rapidly (exceeding 70%), which will have an adverse effect on electrical equipment such as PCS, communication equipment, etc. Utility Model Content

[0039] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of 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 this application.

[0041] In the description of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0042] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0043] This specification provides an energy storage temperature control system. It can be understood that the energy storage temperature control system can be applied to an energy storage cabinet (ie, an energy storage system), such as Figure 1-Figure 4It can also be understood that the energy storage cabinet includes a heat management device and an air-cooled air conditioner. The heat management device can be a PCS and / or an energy storage battery, wherein the position of the PCS and / or the energy storage battery in the energy storage cabinet is not limited, that is, no matter how the PCS and / or the energy storage battery are arranged, the air-cooled air conditioner can adjust the temperature of the energy storage cabinet; the air-cooled air conditioner can be set on the cabinet door of the energy storage cabinet.

[0044] Reference Figure 1-Figure 4 , an energy storage temperature control system provided in this specification may include:

[0045] First air channel,

[0046] The first air duct includes a first air inlet 11, and the first air inlet 11 is arranged corresponding to the air outlet of the air-cooling air conditioner; the air-cooling air conditioner is arranged on the cabinet door of the energy storage cabinet;

[0047] A second air duct, the second air duct includes a second air inlet 12;

[0048] When the air-cooled air conditioner is in working state, the first air inlet 11 is in an open state, and the second air inlet 12 is in a closed state, so that the air outlet of the air-cooled air conditioner blows out cold air, and circulates between the air-cooled air conditioner and the heat management device through the first air duct; the heat management device is arranged in the energy storage cabinet;

[0049] When the air-cooled air conditioner is not in operation, the first air inlet 11 is in a closed state and the second air inlet 12 is in an open state, so that the wind generated in the energy storage cabinet circulates at least in the heat management device through the second air duct.

[0050] Specifically, the first air duct is a circulation loop of the air-cooled air conditioner, which is installed on the door of the energy storage cabinet. The air outlet of the air-cooled air conditioner is equipped with a first fan, and the heat management device is equipped with a second fan (if the heat management device is a plurality of PACKs, each PACK is equipped with a second fan). When the door of the energy storage cabinet is closed, the air outlet of the air-cooled air conditioner is directly opposite to the first air inlet 11 of the first air duct.

[0051] When the air-cooled air conditioner is in working state, the first air inlet 11 is in an open state and the second air inlet 12 is in a closed state. Since the first air inlet 11 is arranged corresponding to the air outlet of the air-cooled air conditioner, the cold air blown out of the air outlet of the air-cooled air conditioner enters the heat management device from the first air inlet 11 through the first fan. After circulating in the heat management device, it is introduced into the air inlet of the air-cooled air conditioner through the second fan of the heat management device, completing the circulation of the cold air blown out by the air-cooled air conditioner, thereby realizing the adjustment of the temperature of the heat management device.

[0052] When the air-cooled air conditioner is in a non-working state, the corresponding first fan also stops working, and the first air inlet 11 is in a closed state. At this time, the second air inlet 12 is in an open state, and the wind in the energy storage cabinet enters the device to be thermally managed through the second air inlet 12. After circulating in the device to be thermally managed, it is blown out through the second fan of the device to be thermally managed, and then enters the device to be thermally managed through the second air inlet 12 of the second channel, so that the wind in the energy storage cabinet at least circulates in the device to be thermally managed, wherein the wind in the device to be thermally managed realizes heat exchange with the outside world to adjust the temperature of the device to be thermally managed.

[0053] It can be understood that an air guide plate is arranged around each device to be heat-managed, so that the wind blown out through the first air duct or the second air duct can enter the device to be heat-managed evenly.

[0054] The energy storage temperature control system provided in the embodiment of the present application can ensure that the cold air of the air-cooled air conditioner is blown into the first air duct through the air outlet of the air-cooled air conditioner to the greatest extent, and then enters the heat management device to the greatest extent, and blows as little as possible outside the heat management device, through the corresponding arrangement of the air outlet of the air-cooled air conditioner and the first air inlet of the first air duct, thereby reducing losses, thereby improving the refrigeration efficiency of the air-cooled air conditioner and reducing the energy consumption of the air-cooled air conditioner.

[0055] When the air-cooled air conditioner is not in working state, the first air inlet is closed and the second air inlet is opened. Therefore, the hot air blown out by the second fan of the heat management device will not enter the first air duct, that is, it will not pass through the evaporator of the air-cooled air conditioner. The water vapor at the evaporator of the air-cooled air conditioner cannot enter the heat management device due to the closure of the first air duct. Therefore, it will not cause the humidity in the cabin where the heat management device is located to be too high, that is, it will not cause moisture to the electrical equipment such as PCS, communication equipment, etc., and produce adverse effects.

[0056] In one embodiment, referring to Figure 2-Figure 4 , the first air duct includes:

[0057] An air collecting box 1, a first side of the air collecting box 1 is a first air inlet 11, and a first baffle 13 is provided at the first air inlet 11;

[0058] The second side of the air collecting box 1 is connected to the interior of the energy storage cabinet.

[0059] Specifically, the first baffle 13 may be a complete baffle or a plurality of baffles arranged in parallel. The plurality of baffles arranged in parallel may be arranged in columns or in rows. Figure 2-Figure 4 In the example, three baffles are arranged in a row. The baffles can be made of a relatively light metal material, and for example, the baffles are made of aluminum sheets.

[0060] The first baffle 13 can be pushed open under a certain wind pressure, and closed when the wind pressure is insufficient. That is, when the air-cooling air conditioner is working and the configured first fan is working, the first baffle 13 can be pushed open under the action of the first fan. Figure 3 and Figure 4 , so that the cold air blown out by the air-cooled air conditioner enters the air collecting box 1 through the first baffle 13 and then enters the interior of the energy storage cabinet (i.e., the heat management device), and the hot air blown out by the heat management device is introduced into the air inlet of the air-cooled air conditioner.

[0061] When the air-cooling air conditioner is not in operation, the first fan also stops working, so the first baffle 13 will be in a closed state. Figure 2 The water vapor at the evaporator of the air-cooled air conditioner cannot enter the heat management device due to the closure of the first baffle 13.

[0062] In this embodiment, by providing an air collecting box, the cold air blown out by the air-cooling air conditioner can enter the heat management device in a more concentrated manner.

[0063] In one embodiment, referring to Figure 2 and Figure 3 The second air duct includes: a second baffle 14; a second air inlet 12 is opened on the third side of the air collecting box 1, and the second baffle 14 is arranged at the second air inlet 12; the third side of the air collecting box 1 is the side close to the device to be heat managed.

[0064] Specifically, the second baffle 14 may be a complete baffle or a plurality of baffles arranged in parallel. The plurality of baffles arranged in parallel may be arranged in columns or in rows. Figure 2 and Figure 3 In the example, a second baffle 14 is provided. The baffle can be made of a metal material of a relatively light material, and for example, the baffle is made of an aluminum sheet.

[0065] When the first air duct is closed, the hot air generated by the heat management device will push the second baffle 14 open under the wind pressure of the corresponding second fan. Figure 2 , enters the air collecting box 1 from the second air inlet 12 and then returns to the device to be heat managed, exchanges heat with the outside world, and realizes temperature regulation of the device to be heat managed.

[0066] It can be understood that the wind resistance of the hot air entering from the air-cooled air conditioner in the first channel is much greater than the wind resistance in the second air duct. Therefore, the wind pressure of the second fan cannot push open the first baffle 13. Therefore, when the first air duct is closed, the hot air blown out by the heat management device will not go through the circulation loop of the air-cooled air conditioner, and will not pass through the evaporator of the air-cooled air conditioner. The water vapor generated at the evaporator of the air-cooled air conditioner cannot enter the heat management device due to the closure of the first air duct. Therefore, it will not cause the humidity in the cabin where the heat management device is located to be too high.

[0067] In one embodiment, continue to refer to Figure 2 and Figure 3 , a protrusion box 2 is provided on the third side of the air collecting box 1, and a side of the protrusion box 2 away from the third side of the air collecting box 1 is a second air inlet 12; the protrusion box 2 is connected to the air collecting box 1;

[0068] The second blocking piece 14 is disposed at the protrusion box 2 .

[0069] Specifically, by providing the protruding box 2, the wind direction can be guided, that is, the hot air blown out by the heat management device is more efficiently introduced into the protruding box 2, enters the air collecting box 1 and then returns to the heat management device.

[0070] In one embodiment, referring to Figure 4 , the second air duct includes: a first baffle 15 and a second baffle 16;

[0071] A second air inlet 12 is formed on the third side of the air collecting box 1, and a first end of the first baffle 15 is connected to the second air inlet 12; a second end of the first baffle 15 is connected to a first end of the second baffle 16, and a second end of the second baffle 16 is connected to the second side of the air collecting box 1;

[0072] The first baffle 15, the second baffle 16 and the second air inlet 12 form a space that is in communication with the interior of the energy storage cabinet;

[0073] The third side of the air collecting box 1 is a side close to the device to be heat managed.

[0074] Specifically, the first baffle 15 and the second baffle 16 divide the air collecting box 1 into two parts, wherein the first part is a first space formed by the first baffle 15, the second baffle 16 and the first air inlet 11 and connected to the interior of the energy storage cabinet, and the second part is a second space formed by the first baffle 15, the second baffle 16 and the second air inlet 12 and connected to the interior of the energy storage cabinet.

[0075] Since the second space is always in an open state, when the air-cooling air conditioner is in a non-working state, the hot air blown out by the device to be heat-managed can enter the device to be heat-managed through the second space.

[0076] In this embodiment, since no baffle is provided, there is no need to use a larger wind pressure to push the baffle open, and therefore the thermal management device can be equipped with a second fan with a smaller wind pressure.

[0077] It can be understood that, based on this embodiment, continue to refer to Figure 4 A protrusion box 2 may also be provided at the second air inlet 12 on the third side of the air collecting box 1 to guide the hot air blown out by the heat management device. The protrusion box 2, the second air inlet 12, the first baffle 15, and the second baffle 16 form a second space.

[0078] In one embodiment, continue to refer to Figure 1 , the energy storage temperature control system also includes:

[0079] The air guide cover 3 is installed at the air inlet of the air-cooled air conditioner and is used to guide the hot air discharged by the heat management equipment into the air inlet of the air-cooled air conditioner.

[0080] Specifically, the air guide cover 3 can guide the hot air discharged from the heat management device to enter the air inlet of the air-cooled air conditioner more efficiently.

[0081] In one embodiment, the energy storage temperature control system further includes:

[0082] A control device is used to control the opening or closing of the first air duct and the second air duct. The control device is not shown in the figure.

[0083] Specifically, the opening or closing of the first air duct and the second air duct can be controlled by a control signal sent by the control device, and the opening angle can also be controlled.

[0084] When the control device is set, when the first air duct includes the first baffle 13 and the second air duct includes the second baffle 14, the first baffle 13 and the second baffle 14 can be respectively installed on the air collecting box 1 through the transmission mechanism, and the control signal sent by the control device controls the transmission mechanism to open the first baffle 13 or the second baffle 14 to an opening angle or close, that is, including fully opening, partially opening and fully closing.

[0085] By setting up a control device, the air duct selection can be controlled more accurately than the selection based on wind pressure. That is, when the air-cooling air conditioner is working, the control device sends a control signal to control the transmission mechanism to open the first baffle 13 and close the second baffle 14, and the wind at this time flows in the first air duct; when the air-cooling air conditioner is not working, the control device sends a control signal to control the transmission mechanism to close the first baffle 13 and open the second baffle 14, and the wind at this time flows in the second air duct.

[0086] In one embodiment, the energy storage temperature control system further includes:

[0087] A heating device is connected to the control device. The heating device is not shown in the figure.

[0088] Specifically, the control device can also control the closing or opening of the heating device according to the temperature and / or humidity of the battery compartment and / or PCS compartment. Specifically, when the air-cooling air conditioner is turned off and the humidity of the battery compartment and / or PCS compartment is greater than the humidity threshold, turn on the heating device. In addition, because the higher the temperature, the higher the dew point, that is, the less likely it is to generate condensation, the generation of condensation in the battery compartment and / or PCS compartment can be further avoided.

[0089] In one embodiment, the energy storage temperature control system further includes:

[0090] A dehumidification device is connected to the control device. The dehumidification device is not shown in the figure.

[0091] Specifically, the control device is used to control the closing or opening of the dehumidification device according to the temperature and / or humidity of the battery compartment and / or the PCS compartment. The dehumidification device is used to dehumidify the battery compartment and / or the PCS compartment, thereby reducing the generation of condensation.

[0092] The present application also provides an energy storage system. Figure 1 , including the energy storage temperature control system provided by any of the above embodiments.

[0093] Specifically, the energy storage system may include only a PCS compartment or a battery compartment, and the energy storage temperature control system provided in the above embodiment may be used for thermal management, that is, the device to be thermally managed is a PCS or an energy storage battery.

[0094] The energy storage system may include a PCS compartment and a battery compartment. The two compartments use the same compartment door (integrated cabinet door). The entire energy storage cabinet uses the energy storage temperature control system provided in the above embodiment for thermal management. The devices to be thermally managed are the PCS and the energy storage battery.

[0095] Alternatively, the energy storage system may include a PCS compartment and a battery compartment, and the doors of the two compartments may be separate and independently controlled to be opened or closed, so as to avoid mutual influence. The PCS compartment adopts a wind-water heat exchanger for thermal management, and the battery compartment adopts the energy storage temperature control system provided in the above embodiment for thermal management, so that the thermal management of the PCS compartment and the battery compartment can be decoupled, and a more flexible thermal management method can be adopted to reduce the energy consumption of the entire system.

[0096] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
