Description

Technical Field

[0001] The present application relates to the technical field of refrigeration equipment, and in particular to an energy storage air conditioner, an energy storage cabinet, and a control method for the energy storage air conditioner. Background Art

[0002] At present, energy storage through power batteries is one of the mainstream technologies for smoothing energy fluctuations and reducing large-scale power grid shocks. Since power batteries generate a lot of heat during the energy storage process, in order to ensure the safety of power battery energy storage, energy storage air conditioners are usually used to cool the power batteries.

[0003] For areas with large temperature differences between day and night, the ambient temperature at night can drop to below zero or even lower. In such low-temperature nighttime environments, when the energy storage air conditioner is cooling, if the compressor speed remains unchanged, the speeds of the evaporating fan and the condensing fan also remain unchanged, the condensing temperature and the evaporating temperature will both decrease, resulting in a decrease in the compression ratio of the refrigerant, and the exhaust pressure of the compressor will be lower than the minimum pressure allowed for long-term operation, thereby reducing the service life of the energy storage air conditioner.

[0049] The technical solution in the present application will be described clearly and in detail below in conjunction with the accompanying drawings. In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B: "and / or" in the text is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of the present application, "multiple" means two or more than two.

[0050] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as suggesting or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0051] At present, energy storage through power batteries is one of the mainstream technologies for smoothing energy fluctuations and reducing large-scale power grid shocks. Since power batteries generate a lot of heat during the energy storage process, in order to ensure the safety of power battery energy storage, energy storage air conditioners are usually used to cool the power batteries.

[0052] For areas with large temperature differences between day and night, the ambient temperature at night can drop to below zero or even lower. In such low-temperature nighttime environments, when the energy storage air conditioner is cooling, if the compressor speed remains unchanged, the speeds of the evaporating fan and the condensing fan also remain unchanged, the condensing temperature and the evaporating temperature will both decrease, resulting in a decrease in the compression ratio of the refrigerant, and the exhaust pressure of the compressor will be lower than the minimum pressure allowed for long-term operation, thereby reducing the service life of the energy storage air conditioner.

[0053] In order to solve the above technical problems, the embodiments of the present application provide an energy storage air conditioner, an energy storage cabinet, and a control method for the energy storage air conditioner, which can increase the service life of the energy storage air conditioner.

[0054] First, please refer to Figures 1 to 3 The present application proposes an energy storage air conditioner, which includes a housing 100, an evaporation component, a condensation component, and a windshield. The housing 100 is formed with a first chamber 101 and a second chamber 102; the evaporation component is disposed in the first chamber 101; the condensation component includes a condenser 131 and a condensation fan 132 disposed in the second chamber 102; the windshield is disposed between the condensation fan 132 and the condenser 131, or disposed on the air outlet side of the condenser 131; wherein the windshield has a first state and a second state, and the ventilation volume of the condenser 131 when the windshield is in the first state is greater than the ventilation volume of the condenser 131 when the windshield is in the second state.

[0055] In the solution provided by the embodiment of the present application, by controlling the windshield disposed between the condenser 131 and the condensing fan 132 in the second chamber 102, or the windshield disposed on the air outlet side of the condenser 131, the windshield is adjusted from the first state to the second state, so that the ventilation volume of the condenser 131 can be reduced, thereby increasing the condensation temperature and the evaporation temperature, increasing the compression ratio of the refrigerant, and raising the exhaust pressure of the compressor 120 to within the operating range. In this way, not only can the condensing fan 132 of the energy storage air conditioner in a low-temperature environment continue to operate at a constant speed, but the compressor 120 can also operate reliably at a constant speed, thereby effectively increasing the service life of the energy storage air conditioner.

[0056] The energy storage air conditioner, energy storage cabinet and control method of the energy storage air conditioner provided in the embodiments of the present application are described in detail below with reference to the drawings in the specification.

[0057] The energy storage cabinet is a container-like box with power batteries installed inside. Power batteries can effectively smooth out energy fluctuations and reduce large-scale power grid shocks through energy storage.

[0058] Power batteries generate a lot of heat during the energy storage process. In order to ensure the safety of power battery energy storage, an energy storage air conditioner is usually installed in the energy storage cabinet to discharge the heat generated by the power battery energy storage from the energy storage cabinet.

[0059] Figures 1 to 3 The structure of an energy storage air conditioner provided by an embodiment of the present application is exemplarily shown. The energy storage air conditioner includes a housing 100, an evaporation assembly including an evaporation fan 111 and an evaporator 112, a compressor 120, a condensation assembly including a condenser 131 and a condensation fan 132, and a capillary tube 140. The compressor 120, the condenser 131, the capillary tube 140 and the evaporator 112 are sequentially connected through pipelines to form a circulation loop of the refrigerant.

[0060] A partition 103 is provided in the housing 100, and the partition 103 divides the internal space of the housing 100 into a first chamber 101 and a second chamber 102. The first chamber 101 and the second chamber 102 are two independent chambers and are not connected to each other. The evaporation fan 111 and the evaporator 112 of the evaporation component are arranged in the first chamber 101, and the condenser 131 and the condensation fan 132 of the condensation component are arranged in the second chamber 102. In addition, the compressor 120 and the condenser 131 can also be arranged in the second chamber 102.

[0061] The first chamber 101 is an indoor chamber, and the first chamber 101 is connected to the internal space of the energy storage cabinet. Driven by the evaporator fan 111, the air in the internal space of the energy storage cabinet can first pass through the evaporator 112 to enter the first chamber 101, and then be discharged from the first chamber 101 through the evaporator fan 111 to the internal space of the energy storage cabinet.

[0062] The second chamber 102 is an outdoor chamber, and the second chamber 102 is connected to the external environment. The housing 100 is provided with an air inlet 104 and an air outlet 105 connected to the second chamber 102, a condensing fan 132 is arranged at the air inlet 104, and a condenser 131 is arranged at the air outlet 105. Under the drive of the condensing fan 132, the external air at the air inlet 104 (lower left corner in the figure) can first pass through the condensing fan 132 to enter the second chamber 102, then pass through the condenser 131 from the second chamber 102, and finally be discharged to the external environment through the air outlet 105 (upper left corner in the figure).

[0063] Due to the large temperature difference between day and night in the region, the ambient temperature at night can drop to below zero or even lower. In such a low temperature environment at night, when the energy storage air conditioner is cooling, if the speed of the compressor 120 remains unchanged, the speeds of the evaporating fan 111 and the condensing fan 132 also remain unchanged, the condensing temperature and the evaporating temperature will both decrease, resulting in a decrease in the compression ratio of the refrigerant, and the exhaust pressure of the compressor 120 is lower than the minimum pressure allowed for long-term operation, thereby reducing the service life of the energy storage air conditioner.

[0064] Therefore, the present application proposes a technical concept of changing the ventilation volume of the condenser 131 to ensure that the energy storage air conditioner can operate reliably in a low-temperature environment. That is to say, for the energy storage air conditioner that cools in a low-temperature environment at night, by reducing the ventilation volume of the condenser 131, increasing the condensation temperature and the evaporation temperature, and increasing the compression ratio of the refrigerant, the exhaust pressure of the compressor 120 is increased to within the operating range. In this way, not only can the condensing fan 132 of the energy storage air conditioner in a low-temperature environment continue to operate at a constant speed, but the compressor 120 can also operate reliably at a constant speed, thereby increasing the service life of the energy storage air conditioner.

[0065] Specifically, the energy storage air conditioner provided in the embodiment of the present application also includes a wind shield, which is arranged between the condensing fan 132 and the condenser 131, or is arranged on the air outlet side of the condenser 131; wherein the wind shield has a first state and a second state, and the ventilation volume of the condenser 131 when the wind shield is in the first state is greater than the ventilation volume of the condenser 131 when the wind shield is in the second state.

[0066] It should be noted that the energy storage air conditioner provided in the embodiment of the present application can be a variable frequency air conditioner or a fixed frequency air conditioner. For a variable frequency air conditioner, when its variable frequency function cannot work normally due to various reasons (such as damage to the inverter), the ventilation volume of the condenser 131 can be adjusted by the wind shield. For a fixed frequency air conditioner, since the speed of its condenser 131 is constant, the ventilation volume of the condenser 131 can also be adjusted by the wind shield.

[0067] It is understandable that, under the premise of achieving the purpose of adjusting the ventilation volume of the condenser 131, the wind shield can adopt different structural forms and can be installed at different positions of the energy storage air conditioner.

[0068] See also Figure 1 In some embodiments of the present application, the wind shield may be a baffle 200. Along the height direction H of the housing 100, the baffle 200 is located between the condensing fan 132 and the condenser 131. One end of the baffle 200 is hinged to the partition 103 and can move around the hinge.

[0069] When the wind shield is a baffle 200, in order to control the baffle 200 to switch between the first state and the second state, the energy storage air conditioner further includes a driving member 210. The driving member 210 is connected to the baffle 200 and can drive the baffle 200 to rotate relative to the partition 103. The driving member 210 can be as follows: Figures 1 to 3 It is directly fixed on the partition 103 as shown, and can also be fixed at a suitable position on the inner wall of the housing 100. The driving member 210 can be a push rod, specifically an electric push rod, a hydraulic push rod, a pneumatic push rod or a linear motion mechanism driven by a motor.

[0070] When the baffle 200 is in the first state, the angle between the baffle 200 and the height direction H of the housing 100 may be a first angle. When the baffle 200 is in the second state, the angle between the baffle 200 and the height direction H of the housing 100 may be a second angle, which is greater than the first angle.

[0071] Since the baffle 200 is hinged to the partition 103, the posture of the baffle 200 changes with the posture of the partition 103. When the partition 103 is vertically arranged, the baffle 200 in the first state can fit the partition 103, and the first angle of the baffle 200 can be approximately 0°. Figure 1 and Figure 2 When the baffle 200 is tilted as shown, the first angle of the baffle 200 can be greater than 0° and less than or equal to 45°, for example, it can be 10°, 20°, 30°, 35°, 40°, 45°, etc. That is, in the first state, the baffle 200 installed on the tilted baffle 103 has a larger first angle than the baffle 200 installed on the vertical baffle 103. Correspondingly, the second angle is greater than the first angle, and when the first angle changes, the second angle also changes accordingly, wherein the second angle can be greater than 45° and less than or equal to 90°, for example, it can be 50°, 60°, 65°, 70°, 85°, 80°, 85°, 90°, etc.

[0072] In addition, in other embodiments of the present application, the wind shield may also be a shutter (not shown in the figure) arranged on the air outlet side of the condensing fan 132, and the opening degree of the shutter in the first state is greater than the opening degree of the shutter in the second state.

[0073] It is understandable that by adjusting the opening of the shutters, the ventilation volume of the condenser 131 can also be adjusted. The shutters can be adjusted manually or automatically. When manual adjustment is adopted, the staff is required to manually adjust the shutters according to the outdoor ambient temperature. When automatic adjustment is adopted, an electric drive device, a magnetic drive device, etc. can be used. When the controller obtains that the outdoor ambient temperature reaches the set temperature, the drive device receives the control instruction and automatically drives the shutters to rotate to achieve the adjustment of the shutters.

[0074] The specific opening size of the blinds in the first state and the second state needs to be flexibly determined according to various parameters such as the blade type, mesh type, mesh size, etc. of the blinds, and the embodiments of the present application do not make specific limitations on this.

[0075] See also Figure 2 and Figure 3 In order to reduce the probability of foreign matter such as dust and gravel in the outdoor environment entering the energy storage air conditioner through the air inlet 104 along with the air, in some embodiments of the present application, the energy storage air conditioner may further include a cover plate 300, the cover plate 300 is connected to the housing 100, the cover plate 300 covers the air inlet 104, the cover plate 300 is provided with a filter 301, and the filter 301 is arranged opposite to the condensing fan 132. Among them, the size of the filter 301 can be determined according to the fan of the condensing fan 132. The structural parameters such as the material and mesh number of the filter 301 can be flexibly determined according to actual needs, and the embodiments of the present application do not limit this.

[0076] The filter 301 can filter the air entering the energy storage air conditioner. However, after the energy storage air conditioner has been running for a long time, the pores on the surface of the filter 301 will inevitably be blocked by foreign matter, so it is necessary to clean the filter 301 to ensure the filtering performance of the filter 301.

[0077] In the embodiment of the present application, the cover plate 300 and the shell 100 of the energy storage air conditioner are optimized in design, and combined with the control of the working state of the wind shield, the filter 301 can be automatically cleaned by vibration.

[0078] Specifically, one end of the cover plate 300 is hinged to the housing 100, and the other end is connected to the housing 100 through an elastic member 310. The elastic member 310 is used to keep the cover plate 300 in a state of covering the air inlet 104. The housing 100 is provided with an air vent 106, and the cover plate 300 also covers the air vent 106. The windshield also has a third state, and the ventilation volume of the condenser 131 when the windshield is in the third state is less than the ventilation volume of the condenser 131 when the windshield is in the second state. Among them, the elastic member 310 can be a return spring, a rubber member, etc.

[0079] As mentioned above, the wind shield may be a baffle 200 or a shutter.

[0080] See also Figure 3If the wind shield adopts a baffle 200, the baffle 200 can be placed in the third state by controlling the driving member 210. At this time, the angle between the baffle 200 and the height direction H of the shell 100 can be greater than 90° and less than or equal to 120°, for example, it can be 95°, 100°, 105°, 110°, 115°, 120°, etc. In this case, due to the existence of the baffle 200, the static pressure of the air around the condenser 131 increases. When the pressure is greater than the elastic force of the elastic member 310, the cover plate 300 can be rotated relative to the shell 100, thereby opening the air vent 106. Part of the air driven by the condensing fan 132 can flow out of the second chamber 102 from the air vent 106. While the vent 106 is open, the static pressure of the air around the condenser 131 will decrease. When the elastic force of the elastic member 310 is greater than the static pressure of the air around the condenser 131, the cover plate 300 rotates relative to the housing 100 under the elastic force of the elastic member 310, and re-covers and closes the vent 106. As the static pressure of the air around the condenser 131 increases, the cover plate 300 swings back and forth relative to the housing 100, and the vent 106 is opened and closed cyclically. When the vent 106 is opened and closed, the cover plate 300 vibrates due to inertia and the contact between the cover plate 300 and the housing 100, so that the filter 301 on the cover plate 300 can also vibrate, and the foreign matter attached to the filter 301 is cleaned off by vibration, so that the filter 301 is automatically cleaned.

[0081] It is understandable that if the windshield member adopts a shutter, the shutter can be placed in the third state, and the opening of the shutter in the third state is less than the opening of the shutter in the second state. At this time, similar to the windshield member adopting the baffle 200, the shutter in the third state can increase the static pressure of the air around the condenser 131, overcome the elastic force of the elastic member 310, and make the cover plate 300 rotate relative to the shell 100 to open the air vent 106, and when the air vent 106 is opened to reduce the static pressure of the air around the condenser 131, the cover plate 300 is rotated relative to the shell 100 under the elastic force of the elastic member 310 to close the air vent 106. When the cover plate 300 swings back and forth relative to the shell 100, the air vent 106 is opened and closed cyclically. In this process, the cover plate 300 and the filter 301 thereon will vibrate, and the foreign matter attached to the filter 301 is cleaned off by vibration.

[0082] The control method of the energy storage air conditioner is described below in conjunction with the working status of the wind shield.

[0083] For areas with large temperature differences between day and night, the energy storage air conditioner of the embodiment of the present application can be controlled to work in different cooling modes. Figure 4 As shown, the control method of the energy storage air conditioner may include the following steps:

[0084] S101, obtaining the outdoor ambient temperature.

[0085] The energy storage air conditioner can obtain the outdoor ambient temperature outside the energy storage cabinet directly or indirectly. For example, the energy storage air conditioner can be connected to a temperature sensor located outside the energy storage cabinet to directly obtain the outdoor ambient temperature. In addition, the energy storage air conditioner can also indirectly obtain the outdoor ambient temperature detected by a temperature detection platform such as a weather station through wireless communication and other methods.

[0086] When the energy storage air conditioner needs cooling, for example, when the temperature inside the energy storage cabinet is greater than the set cooling temperature, the cooling mode of the energy storage air conditioner can be controlled in the following different ways.

[0087] S102, when the outdoor temperature is greater than or equal to a preset temperature, the wind shield is placed in a first state so that the energy storage air conditioner is placed in a first cooling mode;

[0088] The preset temperature is a relatively low temperature, which may be usually 0°C, or a temperature lower than 0°C, such as minus 10°C or even minus 20°C.

[0089] When the outdoor temperature is greater than or equal to the preset temperature, the wind shield can be in the first state, the wind shield does not substantially reduce the ventilation volume of the condenser 131, and the ventilation volume of the condenser 131 can be larger or the maximum value. At this time, the energy storage air conditioner is in the first cooling mode, that is, in the normal cooling mode.

[0090] S103, when the outdoor temperature is lower than a preset temperature, the wind shield is placed in a second state so that the energy storage air conditioner is placed in a second cooling mode.

[0091] When the outdoor temperature is lower than the preset temperature, the wind shield can be placed in the second state, and the wind shield reduces the ventilation volume of the condenser 131. At this time, the energy storage air conditioner is in the second cooling mode, that is, in the low-temperature cooling mode.

[0092] Compared with the ventilation volume of the condenser 131 when the wind shield is in the first state, the ventilation volume of the condenser 131 when the wind shield is in the second state is significantly reduced. Therefore, the condensation temperature and the evaporation temperature can be increased, the compression ratio of the refrigerant can be increased, and the exhaust pressure of the compressor 120 can be increased to within the operating range. In this way, not only can the condensing fan 132 of the energy storage air conditioner in a low temperature environment continue to operate at a constant speed, but also the compressor 120 can operate reliably at a constant speed, thereby increasing the service life of the energy storage air conditioner.

[0093] It should be noted that the embodiment of the present application can also control the energy storage air conditioner to enter the dust removal mode. For example, after the wind shield is kept in the second state for a first preset time, the wind shield is placed in the third state to put the energy storage air conditioner in the dust removal mode.

[0094] The first preset time can be flexibly determined according to the size of the foreign matter outside. When there are many foreign matter outside (for example, it is dusty outside), the first preset time can be set shorter, for example, the first preset time can be set to 1 hour, and when the windshield is kept in the second state for 1 hour, it enters the dust removal mode for a dust removal. When there are fewer foreign matter outside, the first preset time can be set longer to reduce the frequency of dust removal. For example, the first preset time can be set to 12 hours, and when the windshield is kept in the second state for 12 hours, it enters the dust removal mode for a dust removal.

[0095] In addition, the duration of the dust removal mode can also be set. For example, after the wind shield is kept in the third state for a second preset time, the wind shield is placed in the second state or the first state to make the energy storage air conditioner exit the dust removal mode.

[0096] Taking into account that the dust removal mode may generate relatively loud noise and the wind shield in the third state will significantly reduce the ventilation volume of the condenser 131, the dust removal mode is generally set at night when the outdoor temperature is lower and lasts no longer than the second preset time, such as 10 minutes.

[0097] It should be noted that the embodiment of the present application can also control the energy storage air conditioner to enter the dust removal mode. Figure 5 As shown, the control method of the energy storage air conditioner may also include the following steps:

[0098] S201, obtaining the outdoor ambient temperature.

[0099] S202, when the outdoor temperature is greater than or equal to a preset temperature, the wind shield is placed in a first state so that the energy storage air conditioner is placed in a first cooling mode;

[0100] S203, when the outdoor temperature is lower than a preset temperature, the wind shield is placed in a second state so that the energy storage air conditioner is placed in a second cooling mode.

[0101] In this embodiment, steps S201 to S203 may be the same as steps S101 to S103 in the above embodiment, and are not described in detail here.

[0102] S204, when the time when the wind shield is in the second state is greater than a preset time, the wind shield is placed in the third state to put the energy storage air conditioner in a dust removal mode.

[0103] The ventilation volume of the condenser 131 when the wind shield is in the third state is smaller than the ventilation volume of the condenser 131 when the wind shield is in the second state.

[0104] From the contents of the above device embodiment, it can be known that the wind shield of the condenser 131 can be controlled to be in the third state, entering the dust removal mode, so that the filter 301 on the cover 300 vibrates, and foreign matter attached to the filter 301 is cleaned off by vibration, thereby realizing automatic cleaning of the filter 301.

[0105] Exemplarily, after the wind shield is maintained in the second state for a first preset time, the wind shield is placed in the third state to place the energy storage air conditioner in the dust removal mode.

[0106] The first preset time can be flexibly determined according to the size of the foreign matter outside. When there are many foreign matter outside (for example, it is dusty outside), the first preset time can be set shorter, for example, the first preset time can be set to 1 hour, and when the windshield is kept in the second state for 1 hour, it enters the dust removal mode for a dust removal. When there are fewer foreign matter outside, the first preset time can be set longer to reduce the frequency of dust removal. For example, the first preset time can be set to 12 hours, and when the windshield is kept in the second state for 12 hours, it enters the dust removal mode for a dust removal.

[0107] In addition, the duration of the dust removal mode can also be set. For example, after the wind shield is kept in the third state for a second preset time, the wind shield is placed in the second state or the first state to make the energy storage air conditioner exit the dust removal mode.

[0108] Taking into account that the dust removal mode may generate relatively loud noise and the wind shield in the third state will significantly reduce the ventilation volume of the condenser 131, the dust removal mode is generally set at night when the outdoor temperature is lower and lasts no longer than the second preset time, such as 10 minutes.
