Description

Technical Field

[0001] The utility model relates to the technical field of energy storage temperature control, in particular to an energy storage air conditioner. Background Art

[0002] At present, the temperature control schemes for energy storage batteries used in the electrochemical energy storage industry mostly adopt liquid cooling schemes. Specifically, a liquid cooling unit is set on one side of the container energy storage battery. The liquid cooling unit is equipped with a compressor, condenser, expansion valve, refrigerant pipeline, plate exchanger, water pump, battery cold water plate and refrigerant pipeline, etc. Its working principle is: when the unit is running, the heat absorbed by the evaporator (cold water plate) from the refrigerant circulation system is absorbed by the evaporation of the refrigerant. The refrigerant enters the condenser after being compressed by the compressor, and releases the heat to the surrounding air environment through the condensation of the refrigerant. The condensed refrigerant returns to the evaporator through the expansion valve, and then evaporates again, and the cycle repeats. On the refrigerant side: after the refrigerant releases the heat generated by the battery through the evaporator (cold water plate), it uses the power generated by the operation of the water pump to re-enter the cold water plate to absorb the heat generated during the battery charging and discharging process.

[0003] The liquid cooling unit itself can perform mechanical refrigeration to cool the refrigerant, thereby cooling the energy storage battery.

[0073] Combination Figure 2 As shown, a cooling station liquid supply port 14, a cooling station liquid outlet port 15, a unit liquid inlet port 16 and a unit liquid outlet port 17 are formed on the right side wall of the housing 1. The cooling station liquid supply port 14 and the cooling station liquid outlet port 15 are used for externally connecting to a cooling supply end 30, which may be a cooling station system. The unit liquid inlet port 16 and the unit liquid outlet port 17 are used for externally connecting to a cooling demand end 20.

[0074] Exemplarily, the cold demand end 20 may be an energy storage battery compartment.

[0075] Specifically, the cooling station liquid supply port 14, the cooling station liquid outlet port 15, the unit liquid inlet port 16 and the unit liquid outlet port 17 are all fixedly connected to the crossbeam 12 through connecting parts.

[0077] Combination Figure 4 As shown, the heat exchanger 2 is arranged in the installation space 11;

[0078] Specifically, the heat exchanger 2 is a plate heat exchanger 2. The plate heat exchanger 2 is a high-efficiency heat exchanger 2 formed by stacking a series of metal sheets with a certain corrugated shape. Thin rectangular channels are formed between various plates, and heat is exchanged through the plates. The plate heat exchanger 2 is an ideal device for liquid-liquid and liquid-steam heat exchange. It has the characteristics of high heat exchange efficiency, low heat loss, compact and light structure, small footprint, wide application, and long service life. Under the same pressure loss, its heat transfer coefficient is 3-5 times higher than that of the tube heat exchanger 2, and the footprint is one-third of the tube heat exchanger 2. The heat recovery rate can be as high as 90% or more.

[0079] Of course, the type of the heat exchanger 2 includes but is not limited to a plate heat exchanger 2 .

[0080] One end of the first pipeline 3 is connected to the liquid inlet 16 of the unit, and the other end of the first pipeline 3 is connected to the cold end inlet of the heat exchanger 2;

[0081] The water pump 31 is arranged on the first pipeline 3 to transport the coolant in the first pipeline 3. As a heavy component, the water pump 31 is fixed to the bracket at the bottom of the installation space 11 by screws or bolts and is located in the middle.

[0082] Specifically, the water pump 31 has a frequency conversion function, and can adjust the size of the delivered water flow according to the heat emitted by the cold demand end 20, thereby achieving temperature regulation of the cold demand end 20. The heat exchanger 2 is located above the right rear side of the water pump 31.

[0083] Among them, the cold end outlet of the heat exchanger 2 is connected to the unit liquid outlet 17 through the second pipeline 7; the cold supply end inlet of the heat exchanger 2 is connected to the cold station liquid supply port 14 through the third pipeline 8, and the cold supply end outlet of the heat exchanger 2 is connected to the cold station liquid outlet 15 through the fourth pipeline 9.

[0084] In this way, the unit liquid inlet 16, the first pipeline 3, the cold end of the heat exchanger 2, the second pipeline 7, the unit liquid outlet 17 and the cold demand end 20 are sequentially connected to form a closed loop for the circulation of the refrigerant.

[0085] The cold supply end 30 is connected to the cold supply end in sequence through the cold station liquid supply port 14, the third pipeline 8, the cold supply end of the heat exchanger 2, the fourth pipeline 9, and the cold station liquid outlet 15 to form a closed loop, providing cold for the heat exchanger 2, and performing heat exchange between the cold end and the cold supply section inside the heat exchanger 2 to achieve cooling for the cold demand end 20.

[0086] Specifically, by arranging the casing 1, the heat exchanger 2, the first pipeline 3 and the water pump 31, an installation space 11 is formed in the casing 1, and the cold station liquid supply port 14 and the cold station liquid outlet port 15 on the casing 1 are used for externally connecting to the cold supply end 30, and cooling is provided through the cold supply end 30; the unit liquid inlet port 16 and the unit liquid outlet port 17 on the casing 1 are used for externally connecting to the cold demand end 20; the cold supply end 30 is connected with the cold supply end of the heat exchanger 2 to provide cooling to the cold supply end, and the cold demand end 20 is connected with the cold receiving end of the heat exchanger 2, and the cold receiving end exchanges heat with the cold supply end, so that the cold supply end 30 cools down the cold demand end 20, and for sites with the conditions for centralized cooling of cold stations, the temperature control energy efficiency can be greatly improved and the cost can be reduced; at the same time, there is no need to configure components such as compressors and condensers, which can reduce the floor space and improve the production and construction efficiency.

[0087] Combination Figure 5 and Figure 7 As shown, in some embodiments of the present application, the energy storage air conditioner further includes an expansion tank 32 .

[0088] The expansion tank 32 is connected to the first pipeline 3 through a branch pipe 34, and the inlet of the expansion tank 32 is connected to the inlet of the water pump 31; this is because the pressure at the inlet of the water pump 31 is the lowest. By connecting the expansion tank 32 to the inlet position of the water pump 31 and designing the expansion tank 32 near the upper end of the water pump 31, the cost of the pipeline can be effectively saved.

[0089] Combination Fig.11 As shown, when the temperature of the refrigerant in the first pipeline 3 increases, the refrigerant expands due to the principle of thermal expansion and contraction, and the excess refrigerant due to the expansion can enter the expansion tank 32 for temporary storage. When the temperature of the refrigerant in the first pipeline 3 drops, the volume of the refrigerant decreases, and the refrigerant in the expansion tank 32 flows back to the first pipeline 3 under the pressure of the expansion tank 32, thereby ensuring that the refrigerant in the first pipeline 3 is maintained within the normal operating range.

[0090] The first filter 33 is disposed on the first pipeline 3 and is located between the expansion tank 32 and the liquid inlet 16 of the unit.

[0091] Specifically, by providing the first filter 33, the first filter 33 is used to remove particulate impurities contained in the coolant, so as to protect the water pump 31, instruments and other equipment, enable them to work normally, and extend the service life of the equipment.

The tank body of the expansion tank 32 has a support foot 321, and the support foot 321 is located in the projection area of ​​the expansion tank 32 on the first fixing plate 4. The expansion tank 32 is fixed to the first fixing plate 4 by the support foot 321.

[0097] Specifically, by fixing the expansion tank 32 on the first fixing plate 4, the first fixing plate 4 is detachably fixed on the casing 1, which is convenient for installation and removal of the expansion tank 32 and later maintenance.

[0098] In some embodiments of the present application, the bottom of the first fixed plate 4 is bent toward the inlet of the expansion tank 32 to form a bending portion 41, and the bending portion 41 extends to the bottom of the expansion tank 32. The bending portion 41 can support the expansion tank 32 to a certain extent, and an open groove 411 is formed on the bending portion 41, and the opening groove 411 is used to avoid the inlet of the expansion tank 32.

[0099] In some embodiments of the present application, in order to improve the structural strength of the bending portion 41 , reinforcing ribs are welded between the bending portion 41 and the main body of the first fixing plate 4 .

[0103] The second fixing plate 6 has a U-shaped or C-shaped structure. The second fixing plate 6 is circumferentially arranged on the outside of the insulation layer. The two ends of the second fixing plate 6 are fixedly arranged on the vertical beam 13 on the left side wall of the casing 1. The fasteners pass through the second fixing plate 6 and the insulation layer to fix the second fixing plate 6 to the heat exchanger 2.

[0104] Specifically, on the one hand, the second fixing plate 6 is wrapped around the outside of the insulation layer to prevent the insulation layer from falling off and ensure the reliability of the insulation layer attached to the surface of the heat exchanger 2. On the other hand, the second fixing plate 6 can help improve the installation stability of the heat exchanger 2.

[0105] Exemplarily, two opposite surfaces of the second fixing plate 6 are fixedly connected to the heat exchanger 2 by four screws respectively.

[0107] The second pipeline 7 is connected between the cold end outlet of the heat exchanger 2 and the unit liquid outlet 17;

[0109] Specifically, the opening and closing parts of the safety valve 71 are in a normally closed state under the action of external forces. When the medium pressure in the equipment or pipeline exceeds the specified value, the medium is discharged to the outside of the system to prevent the medium pressure in the pipeline or equipment from exceeding the specified value.
