Description

Technical Field

[0001] This utility model belongs to the field of air conditioning technology and relates to an energy storage air conditioner. Background Technology

[0002] To encourage users to rationally schedule their electricity consumption and improve the efficiency of power resource utilization, a peak-valley electricity policy is currently adopted. During the day, electricity consumption is more concentrated, power supply is tight, and the charging standard is higher; at night, fewer electricity users and power supply is more abundant, and the charging standard is lower. Energy storage air conditioners are air conditioning devices that store energy at night and release cool air during the day.

[0003] For example, a multi-functional household off-peak electricity ice-making and energy storage air conditioner disclosed in the patent document (application number: 201520026951.6) includes a compressor, a condenser, a liquid storage tank, a thermal expansion valve, and an energy storage box. The energy storage box includes a box body, which is divided into an upper water chamber and a lower mounting chamber by a partition. The lower mounting chamber is used to install components such as the evaporator, and the upper water chamber is used to hold water. The fan is mounted on the side wall, and the condenser pipe is mounted on a U-shaped baffle. The U-shaped baffle is vertically slidably connected to the top plate of the box body and supported by a spring. There is also a pressure block that presses on the U-shaped baffle. At night, under the action of the pressure block, the condenser pipe descends to the bottom of the upper water chamber and is immersed in water to freeze. During the day, the pressure block is removed, and the U-shaped baffle rises with the condenser pipe under the spring, so that the ice block on the condenser pipe is opposite to the fan.

[0004] The reason for the condenser tube's lifting mechanism is that the water level in the upper water chamber cannot be higher than the fan. Therefore, the ice that forms in the water is lower than the fan, requiring the bottom ice to be raised. This results in frequent raising and lowering of the condenser tube. Since the condenser tube is made of rigid copper, a flexible hose is needed for connection, leading to leaks at the connection points. Furthermore, frequent raising and lowering of the condenser tube also causes it to age prematurely, resulting in low reliability. The condenser tube needs to be raised and lowered because it is misaligned between the fan and the ice in the water. Therefore, those skilled in the art can easily conceive of moving another opposing component without moving the condenser tube, such as enlarging the air outlet so that the fan lowers to be opposite the ice. Of course, a gate-like structure would also need to be installed at the bottom of the fan to block the lower part of the air outlet when the fan rises. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing an energy storage air conditioner that can improve reliability while ensuring cooling performance.

[0006] The objective of this utility model can be achieved through the following technical solution: an energy storage air conditioner, comprising a housing with an air inlet and an air outlet respectively opened on opposite side walls, a fan installed at the air outlet or air inlet of the housing, and an evaporator provided inside the housing, characterized in that the evaporator is fixed on the housing and opposite to the air outlet, and a water tank located below the evaporator is also provided inside the housing, the water tank having an upward opening opposite to the evaporator above, and a drive mechanism on the housing capable of raising and lowering the water tank, and the water tank being able to rise until the evaporator is located inside the water tank.

[0007] The casing is made of insulating material. A fan is installed at the air inlet or outlet to generate airflow from the inlet to the outlet. The evaporator is connected to an external compressor and condenser. This application fixes the evaporator inside the casing and always faces the fan on one side. Importantly, there is space below the evaporator for a liftable water tank located inside the casing. This water tank is larger than the evaporator and is filled with water. When ice storage is needed at night, the water tank is raised via a drive mechanism. The tank opening faces upwards and is aligned with the evaporator above. As the tank rises, the evaporator enters the tank through the opening. The compressor operates, the evaporator cools, and gradually begins to freeze. The ice condenses on the outside of the evaporator and gradually grows larger. As the ice grows larger, the amount of cooling energy transferred by the evaporator gradually decreases. A certain amount of liquid water remains between the ice and the inner wall of the tank, which can be controlled by volume and power to prevent the ice from adhering to the inner wall of the tank. When cold air needs to be released during the day, the water tank is lowered by a drive mechanism, exposing the ice block condensed on the evaporator. The entire ice block is opposite to the fan, and the airflow generated by the fan can flow from the air inlet on one side of the ice block to the air outlet on the other side. The airflow passes over the surface of the ice block and carries away the cold energy to improve the cooling effect. Therefore, the liftable water tank can avoid the water tank covering the outside of the ice block and affecting the release of cold energy, thus ensuring the cooling effect. At the same time, the structural design of the water tank to lift water to the evaporator in this application means that the copper tube evaporator does not need to be raised or lowered, thereby ensuring the structural stability and reliability of the evaporator.

[0008] In the aforementioned energy storage air conditioner, the evaporator is plate-shaped, and there are at least two evaporators. The sides of adjacent evaporators face each other, forming a ventilation gap opposite to the air outlet. The plate-shaped evaporator allows the condensed ice to form thinner blocks, providing a larger contact area with the airflow and improving heat exchange efficiency. Furthermore, multiple evaporators condense into multiple ice blocks, allowing airflow to exchange heat with two ice blocks as it passes through the gaps between them. This not only improves the cooling effect but also reduces airflow resistance, making it more energy-efficient and environmentally friendly.

[0009] In the aforementioned energy storage air conditioner, the evaporator is flat and arranged horizontally and sequentially along the vertical direction, or the evaporators are arranged vertically and sequentially along the horizontal direction. This sequential arrangement of evaporators makes the condensed ice blocks more regularly spaced, and the gaps between the ice blocks for airflow are more uniform. This improves the cooling effect and ensures that the cold air blown from the outlet is evenly distributed, resulting in better comfort.

[0010] In the aforementioned energy storage air conditioner, the evaporator is cylindrical, with its inner hole horizontally positioned and facing the air outlet. All evaporators have the same diameter and are arranged in a matrix, or all evaporators have different diameters, with smaller diameter evaporators inserted inside larger diameter evaporators. The cylindrical shape of the evaporator causes the condensed ice to also be cylindrical, with its two ends facing the air inlet and outlet respectively. Airflow passes through the inner and outer sides of the cylindrical ice, improving the cooling effect.

[0011] In the aforementioned energy storage air conditioner, the drive mechanism includes a lifting frame located above the housing. Several vertically arranged support rods are fixed to the upper side of the housing. Several guide sleeves are fixed to the lifting frame, each slidingly fitted onto one of the support rods. Several vertically arranged lifting rods are fixed to the lifting frame, with their lower ends extending downwards into the housing and fixedly connected to a water tank. The housing is also equipped with a motor, winch, or cylinder capable of driving the lifting frame to move up and down. The lifting frame is located above the exterior of the housing and connected to the water tank inside the housing via the lifting rods. The lifting frame slides between the guide sleeves and support rods to ensure stability and is driven by a motor, cylinder, or hydraulic cylinder. For example, the motor can be connected to the lifting frame via a screw and nut structure, a pulley structure, or a rope. The drive end of the cylinder or hydraulic cylinder is directly connected to the lifting frame, resulting in structural stability and high reliability.

[0012] In the aforementioned energy storage air conditioner, the water tank includes an inner casing and an outer casing fixedly connected to each other, forming an insulation cavity between the inner and outer casings. Several guide rods are vertically fixed inside the casing, and several guide tubes are vertically fixed inside the insulation cavity. The lower ends of the guide rods are slidably inserted into the guide tubes. The insulation cavity serves as a heat insulation layer; additionally, it can be filled with insulation material. This allows the water tank to rise while the evaporator freezes inside, keeping the internal ice and liquid water warm, preventing cold loss, improving energy storage freezing efficiency, and increasing energy savings. The guide tubes located between the inner and outer casings cooperate with the guide rods fixed inside the casing to ensure the stability of the water tank's rise and fall, as well as the accuracy of its position after rising. A more precise position after rising ensures more accurate and uniform ice formation on the evaporator, improving cooling efficiency. A more precise position after falling ensures alignment with the ice above, allowing the melted liquid water to fall into the water tank, improving reliability.

[0013] In the aforementioned energy storage air conditioner, the side of the water tank facing the air inlet and outlet is attached to the inner side of the casing. When the water tank rises to the point where the evaporator is inside, it can cover the air inlet and outlet. After the water tank rises, it can cover the air inlet and outlet through the side wall, preventing the loss of cold energy during ice making, improving ice making efficiency, and saving energy. Moreover, this structure eliminates the need for additional cover plates for the air inlet and outlet, as well as the drive components for opening and closing the cover plates. This allows the water tank to serve a dual purpose, reducing production costs. Furthermore, reducing the number of drive components simplifies the structure and improves reliability.

[0014] In the aforementioned energy storage air conditioner, there are several groups of evaporators arranged vertically. Each group of evaporators has a water tank below it, and these water tanks are fixedly connected. Each water tank can rise to the level of an adjacent group of evaporators. There are several air inlets, each corresponding to one of the groups of evaporators. Each water tank has a baffle vertically fixed to its side, which covers the air inlet when the water tank rises. This structure divides the evaporators into several groups, reducing the height of each group and consequently the height of the water tank. This reduces the travel distance of the water tank during lifting, resulting in lower energy consumption. When the water tank rises to make ice, the baffle covers the air inlet, reducing cold loss and improving ice-making efficiency.

[0015] In the aforementioned energy storage air conditioner, the water tank includes a ring-shaped frame and a waterproof bag with its opening fixed to the frame. The aforementioned lifting rod is fixed to the frame. A water receiving bucket is also provided inside the housing, with its opening facing upwards and located below the water tank. A first water pump is also provided inside the housing to transport water from the receiving bucket to the waterproof bag. The structure and volume of the rigid water tank need to be coordinated with the evaporator and the volume of the condensed ice. Therefore, the rigid water tank has a relatively high height. A greater height space than the water tank height must be reserved below the evaporator inside the housing. For this purpose, a waterproof bag is designed. When the frame rises, the waterproof bag unfolds and covers the outside of the evaporator. The first water pump delivers water into the waterproof bag. When the waterproof bag descends, the bottom of the waterproof bag contacts the water receiving bucket first. As the frame descends further, the waterproof bag can gradually fold, and the internal water enters the water receiving bucket. This structure can make full use of the horizontal space at the bottom of the housing, reduce the height of the water receiving bucket, and make the overall housing height lower and the structure more compact.

[0016] In the aforementioned energy storage air conditioner, a support plate is horizontally fixed inside the casing. This support plate is located below the waterproof bag, and its area is smaller than the opening area of ​​the water receiving tank. Several protective rods are vertically fixed to the edge of the upper side of the support plate, and these protective rods are arranged sequentially and at intervals along the edge of the support plate. Several guide holes are opened along the length of the frame, and the protective rods pass through the guide holes of the frame. The bottom of the waterproof bag is supported on the support plate. When the frame rises, the support plate can withstand the weight of the liquid water inside the waterproof bag, improving the reliability of the waterproof bag. When the frame descends, it does not need to enter the water receiving tank; the waterproof bag quickly begins to fold under the obstruction of the support plate, and the water falls into the water receiving tank below. The support plate not only supports the waterproof bag, improving its reliability, but also reduces the lifting and lowering stroke of the frame.

[0017] In the aforementioned energy storage air conditioner, a heat exchanger is installed at the air outlet of the casing, and a second water pump is also provided inside the casing. The inlet of the second water pump is connected to the water tank through an inlet pipe, and the outlet of the second water pump is connected to the inlet of the heat exchanger through an outlet pipe. The outlet of the heat exchanger is connected to the water tank through a return pipe.

[0018] The temperature of the melted ice water is still low, so a heat exchanger is installed at the air outlet. A second water pump delivers the melted ice water from the tank to the heat exchanger. The airflow, cooled by the ice, further exchanges heat with the heat exchanger as it passes through the air outlet, thereby further reducing the airflow temperature, improving the cooling effect, and making full use of the cooling capacity. Alternatively, an auxiliary evaporator can be added to the tank. When the temperature of the ice water in the tank rises, the auxiliary evaporator can be used to cool the water in the tank, ensuring the heat exchanger's cooling effect on the airflow.

[0019] Compared with existing technologies, this energy storage air conditioner has the following advantages:

[0020] 1. Because the shell is equipped with a water tank that can be raised and lowered, water is lifted by the water tank to the evaporator for ice making, so that the copper tube evaporator does not need to be raised and lowered, thus ensuring the structural stability and reliability of the evaporator.

[0021] 2. When releasing cold air, the water tank is lowered by the drive mechanism, exposing the ice block condensed on the evaporator. The entire ice block is opposite to the fan, and the airflow passes over the surface of the ice block and carries away the cold energy to improve the cooling effect. Therefore, the liftable water tank can avoid the water tank being covered by the outside of the ice block, which would affect the release of cold energy and ensure the cooling effect.

[0022] 3. Because the side of the water tank is attached to the inner side of the shell, when the water tank rises to the point where the evaporator is inside the water tank, the water tank can cover the air inlet and outlet, preventing the loss of cold energy during the ice-making process, improving ice-making efficiency, and making it more energy-efficient.

[0023] 4. Because the water tank uses a waterproof bag, the waterproof bag unfolds and covers the outside of the evaporator when the frame rises. When the waterproof bag descends, it quickly begins to fold under the obstruction of the support plate, and the water falls into the water receiving bucket below. The support plate not only supports the waterproof bag and improves the reliability of use, but also reduces the lifting stroke of the frame.

[0024] 5. Because a heat exchanger is installed at the air outlet, the second water pump can transport the melted ice water from the water tank to the heat exchanger. The airflow cooled by the ice can further exchange heat with the heat exchanger when passing through the air outlet, thereby further reducing the airflow temperature, improving the cooling effect, and making full use of the cooling capacity.

[0043] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0044] Example 1:

[0045] like Figure 1 , Figure 2As shown, an energy storage air conditioner includes a rectangular casing 1. The side walls of the casing 1 can be thin-walled hollow structures, filled with insulation material. An air inlet 11 and an air outlet 12 are respectively opened on opposite sides of the upper part of the casing 1. The air inlet 11 is rectangular, and the air outlet 12 is circular, with the air inlet 11 and air outlet 12 facing each other. Both the air outlet 11 and air outlet 12 are covered by a grille. A fan 2 is installed at the air outlet 12. An evaporator 3 and a water tank 4 are provided inside the casing 1. The evaporator 3 is fixed between the air inlet 11 and air outlet 12, so that the evaporator 3 is directly opposite the air outlet 12. The water tank 4 is located below the evaporator 3, and is rectangular with an upward-facing opening 41. This opening 41 is directly opposite the evaporator 3 above, and the vertical downward projection of the evaporator 3 is located within the opening 41 of the water tank 4. A drive mechanism 5 is also provided on the housing 1. The drive mechanism 5 can drive the water tank 4 to rise and fall. The water tank 4 can rise until the evaporator 3 is completely inside the water tank 4, or it can fall until the evaporator 3 is completely outside the water tank 4. Of course, in the actual processing, the drive mechanism can also be set at the bottom or side of the housing.

[0046] Specifically, combined Figure 3 , Figure 4 , Figure 5 As shown, a rectangular frame-shaped fixing bracket 6 is horizontally fixed on the top surface of the inner shell 1. The evaporator 3 is a rectangular flat plate, and there are several evaporators 3. The several evaporators 3 are all horizontally arranged and arranged vertically at intervals, so that ventilation gaps 9 are formed between adjacent evaporators 3. The two ends of the ventilation gaps 9 are respectively opposite to the air inlet 11 and the air outlet 12. The evaporator 3 includes a refrigeration copper tube 31, which is coiled into an S-shape. Several metal rods 32 are fixed on the upper and lower sides of the refrigeration copper tube 31. The several metal rods 32 are parallel to each other and evenly arranged in sequence. Two long strip-shaped clamps 33 are also fixed on the outside of the metal rods 32. The clamps 33 are perpendicular to the metal rods 32, and the two clamps 33 on the upper and lower sides are arranged opposite each other. Reinforcing rods 34 are vertically fixed at both ends of the clamps 33. Several fixing rods 61 are vertically fixed on the fixing bracket 6. The several fixing rods 61 pass downward through the clamps 33 of the several evaporators 3 and are fixedly connected to the clamps 33.

[0047] Combination Figure 6As shown, the water tank 4 includes an inner casing 42 and an outer casing 43 fixedly connected to each other. An insulation cavity 44 is formed between the inner casing 42 and the outer casing 43. The insulation cavity 44 can be filled with insulation material. Four guide rods 62 are vertically fixed on the fixing frame 6 inside the shell 1. Four guide tubes 45 are vertically fixed inside the insulation cavity 44. These four guide tubes 45 are distributed near the four corners of the water tank 4. The lower ends of the four guide rods 62 are slidably inserted into the four guide tubes 45, guiding the water tank 4 to rise and fall. The side of the outer casing 43 facing the air inlet 11 and the air outlet 12 rests against the inner side of the shell 1. When the water tank 4 rises to the point where the evaporator 3 is inside the water tank 4, the water tank 4 can cover the air inlet 11 and the air outlet 12. Figure 7 As shown, the drive mechanism 5 includes a lifting frame 51 located above the housing 1. The lifting frame 51 includes a lifting plate 511 and four connecting arms 512 extending radially from the lifting plate 511. A fixed plate 52 is fixed on the top surface of the housing 1. Four support rods 53 are vertically fixed on the fixed plate 52. A mounting plate 54 is horizontally fixed on the top of the four support rods 53. Four guide sleeves 513 are fixed on the lifting plate 511. The four guide sleeves 513 are slidably sleeved on the four support rods 53, so that the four connecting arms 512 extend horizontally to the four corners of the housing 1. Lifting rods 55 are also vertically fixed at the ends of the four connecting arms 512. Four through holes 13 are opened on the top surface of the housing 1. The lower ends of the four lifting rods 55 pass downward through the four through holes 13 and extend into the housing 1 and are fixed to the water tank 4. A motor 56 is fixed on the mounting plate 54. The motor shaft of the motor 56 is vertically downward and is fixedly connected to a lead screw 561. A nut 562 is fixed at the center of the lifting plate 511. The lead screw 561 passes through the nut 562 and the two are screwed together.

[0048] During use, water is filled into the water tank 4. At night, when the stored energy freezes, the motor 56 drives the lead screw 561 to rotate. The lead screw 561 drives the lifting frame 51 to rise through the nut 562. The lifting frame 51 raises the water tank 4 through the lifting rod 55, so that the evaporator 3 is submerged in the water in the water tank 4. At this time, the two side walls of the water tank 4 cover the air inlet 11 and the air outlet 12 respectively to prevent the loss of cold energy. The water in the water tank 4 freezes on the evaporator 3. During the day, when air conditioning is needed, the motor 56 drives the lifting frame 51 to descend, so that the water tank 4 is lowered until the ice blocks are completely exposed above the water tank 4. At this time, multiple ice blocks arranged one above the other correspond to the air inlet 11 and the air outlet 12. The pneumatic fan 2 blows air in from the air inlet 11, carrying away the cold energy of the ice blocks and blowing it out from the air outlet 12. The liquid water from the melting ice blocks drips into the water tank 4 below.

Figure 8As shown, the evaporators 3 are arranged in pairs, with a total of three groups. The two evaporators 3 in the same group are arranged vertically with spacing between them. The three groups of evaporators 3 are arranged vertically with spacing between them. The housing is also provided with three air inlets 11, which are respectively opposite to the three groups of evaporators 3. Each group of evaporators 3 is provided with a water tank 4 below it. The height of the water tank 4 is only required to meet the height of two evaporators 3. All three water tanks 4 are fixed on the lifting rod 55. A baffle 48 is fixed on the side of the water tank 4. When the water tank 4 rises, the baffle 48 can cover the air inlet 11. The outside of the air outlet 12 is provided with an openable cover 14. Compared with the first embodiment, the height of the water tank 4 is lower and the lifting range is smaller, only requiring to meet the height of two evaporators 3.
