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] An automatic ice-making air conditioner, as disclosed in patent document (application number: 201320509709.5), includes a casing with an air outlet at the top and an air supply device inside the outlet. Inside the casing are a water tank and an ice-making device. The water tank holds water for ice making and has an open top located at the bottom of the casing. The ice-making device includes an ice storage tank, a water pumping device, a guide pipe, an ice-making tank, an evaporator, a condenser, and a compressor. The ice storage tank is located on top of the water tank, and its bottom has a filter screen communicating with the water tank opening. A water pumping device is located at the bottom of the water tank, connected to the guide pipe, which guides water from the water tank to the ice-making tank at the top of the ice storage tank. The evaporator is located in the ice-making tank and has a grid on the casing. Ice is made by the evaporator at night and poured into the ice storage tank. During the day, a fan operates, and air enters through the grid, then through the air inlet, where it is cooled by the ice and expelled from the air outlet. However, the airflow speed is relatively fast, and the heat exchange with the ice is not sufficient, which affects the refrigeration efficiency. Therefore, those skilled in the art can easily think of increasing the lateral size of the ice storage tank to increase the airflow path, while increasing the ice-making power and the number of ice blocks. However, this will also increase the equipment cost and energy consumption. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing an energy storage air conditioner that can improve cooling efficiency while reducing equipment costs and energy consumption.

[0005] The objective of this utility model can be achieved through the following technical solution: An energy storage air conditioner includes a housing with an air inlet and an air outlet respectively opened on opposite side walls. A fan is installed at the air inlet or air outlet of the housing. An energy storage box, a main evaporator, a water storage tank, and a water pump are provided inside the housing. The top of the energy storage box is open and located between the air inlet and the air outlet. The main evaporator is located inside the energy storage box. A heat exchanger is installed at the air outlet or air inlet of the housing. The energy storage box is connected to the water inlet of the water pump through a drain pipe. The water storage tank is connected to the water inlet of the water pump through a water inlet pipe. The water outlet of the water pump is connected to the water inlet of the heat exchanger through a water outlet pipe. The water outlet of the heat exchanger is connected to the water storage tank through a return pipe. Control components capable of controlling the on / off state are provided on both the drain pipe and the water inlet pipe. A water outlet valve assembly capable of supplying water to the energy storage box is provided on the water outlet pipe.

[0006] The casing is made of insulating material. The energy storage tank, main evaporator, and water pump are all fixed inside the casing. The main evaporator is connected to the external compressor and condenser. The air inlet and outlet are located on the left and right sides of the casing. The top opening of the energy storage tank is located between the air inlet and outlet, so the air inlet, outlet, fan, and heat exchanger are all higher than the energy storage tank. When ice storage is needed at night, the control on the drain pipe blocks the drain pipe, the control on the inlet pipe opens the inlet pipe, the outlet valve assembly opens, and the water pump works to transport water from the storage tank to the outlet pipe through the inlet pipe. Then, the lower outlet valve assembly releases water into the energy storage tank. The main evaporator inside the energy storage tank makes ice. The ice blocks are smaller than the volume of the energy storage tank and are submerged in cold water. When cooling is needed during the day, the fan turns on, and the airflow enters through the air inlet. As it passes through the opening of the energy storage tank, it exchanges heat with the surface of the ice and the water, reducing the airflow temperature. At the same time, the control on the water inlet pipe blocks the water inlet pipe, while the control on the drain pipe opens the drain pipe. The water outlet valve assembly closes, and the water pump can transport the unfrozen ice water and the melted ice water in the energy storage tank through the drain pipe to the water outlet pipe and then into the heat exchanger. The airflow, cooled by the ice, can further exchange heat with the heat exchanger as it passes through the air outlet, thereby further reducing the airflow temperature and improving the cooling effect.

[0007] By optimizing the control components and outlet valve assembly, a single water pump powers both the nighttime water supply to the energy storage tank and the daytime water supply to the heat exchanger, achieving dual functionality with a single pump. This reduces the number of pumps required and lowers equipment costs. Furthermore, the chilled water in the heat exchanger originates from the energy storage tank, utilizing chilled water obtained during nighttime ice making and from melted ice during the day. This eliminates the need for a high-energy-consuming evaporator during the day, resulting in greater energy savings. Especially as water is gradually extracted from the energy storage tank, ice is exposed above the water surface, allowing airflow to contact the entire outer surface of the ice, increasing the heat exchange area and improving cooling efficiency.

[0008] In the aforementioned energy storage air conditioner, the water outlet valve assembly includes a drain pipe and an electric valve mounted on the drain pipe. One end of the drain pipe is connected to the outlet pipe, and the other end is located above the opening of the energy storage tank. The height of the other end of the drain pipe is lower than the height of the heat exchanger's inlet. The drain pipe is slightly higher than the energy storage tank, and the other end of the drain pipe is the outlet port, allowing water to be discharged into the energy storage tank. In particular, the height of this outlet port is lower than the height of the heat exchanger's inlet. Utilizing this height difference, when the electric valve is opened at night for ice making, water flows directly from the drain pipe into the energy storage tank without entering the higher-positioned heat exchanger. When the electric valve is closed during the day for cooling, water from the outlet pipe can only enter the heat exchanger. This structure requires only one electric valve to control the water flow in both directions between the energy storage tank and the heat exchanger, reducing the number of electric valves and lowering equipment costs.

[0009] In the aforementioned energy storage air conditioner, the water pump's inlet is connected to a T-junction pipe. One end of the drain pipe is connected to the bottom of the energy storage tank, and the other end is connected to one port of the T-junction pipe. One end of the inlet pipe extends into the water storage tank, and the other end is connected to the other port of the T-junction pipe. The control components include two electric valves installed on the drain pipe and the inlet pipe respectively. The drain pipe, connected to the bottom of the energy storage tank, allows for the complete drainage of the ice water within the tank, exposing the ice and improving the cooling effect. The drain pipe and the inlet pipe are independently controlled by their respective electric valves, enhancing operational reliability.

[0010] In the aforementioned energy storage air conditioner, a guide shell is fixed at the air inlet of the housing. The lower side plate of the guide shell gradually slopes downwards from the outside to the inside. The fan is obliquely installed at the outer end port of the guide shell, facing the opening at the top of the energy storage box. The fan is higher than the energy storage box, and its oblique setting and orientation towards the opening of the energy storage box allow airflow to be directly blown onto the ice blocks inside the energy storage box under the action of the guide shell, reducing wind resistance and noise, and improving the cooling effect.

[0011] In the aforementioned energy storage air conditioner, the two side panels of the energy storage box near the air inlet and outlet are both inclined, and the distance between the two side panels gradually increases from bottom to top. The main evaporator is formed by coiled refrigeration coils, and there are gaps between the main evaporator and the inner side and bottom of the energy storage box. After the ice water in the energy storage box is drained, a channel is formed between the lower surface of the ice block and the inner side and bottom of the energy storage box. Some airflow flows directly from above the ice block and exchanges heat with the upper surface of the ice block, while some airflow enters the energy storage box and is guided by the inclined side panels of the energy storage box to exchange heat with the side and bottom of the ice block, thereby improving the cooling effect.

[0012] In the aforementioned energy storage air conditioner, a guide plate is also fixed inside the casing. This guide plate is located above the energy storage box, with its middle section horizontally positioned near the top opening of the energy storage box. Both ends of the guide plate are bent upwards at an angle, facing the air inlet and air outlet respectively. The horizontal middle section of the guide plate forms a channel with the upper surface of the ice block. Airflow is guided downwards through the angled section near the air inlet, allowing the airflow to fully act on the ice block. Then, the airflow is guided again by the angled section near the air outlet and blown out from the outlet, reducing wind resistance and noise, and improving the cooling effect.

[0013] In the aforementioned energy storage air conditioner, the air outlet is rectangular, and the heat exchanger consists of S-shaped coiled heat exchange tubes arranged in a plate shape. The heat exchanger is vertically positioned and covers the air outlet. This allows for thorough heat exchange between the airflow and the heat exchanger as it passes through the air outlet, improving the cooling effect.

[0014] In the aforementioned energy storage air conditioner, the water storage tank is located below the energy storage unit, and an auxiliary evaporator is also installed inside the water storage tank. During daytime cooling, the ice water in the energy storage tank will gradually drain away, making it difficult to continuously supply ice water to the heat exchanger. However, when the water returns to the water storage tank after heat exchange through the return pipe, the water temperature is still low. At this time, the second solenoid valve on the drain pipe is closed, and the second solenoid valve on the inlet pipe is opened, allowing the ice water in the water storage tank to be transported to the heat exchanger for reuse. When the cooling effect of the water in the water storage tank is poor, but air conditioning is still needed, an additional auxiliary evaporator is installed inside the water storage tank to cool the water in the tank, maintaining the ice water supply to the heat exchanger and ensuring the cooling effect.

[0015] An energy storage air conditioner includes a housing with air inlets and outlets on opposite side walls. A fan is installed at either the air inlet or outlet. An energy storage box, a main evaporator, a water tank, and a water pump are housed within the housing. The top of the energy storage box is open and located between the air inlet and outlet. The main evaporator is located inside the energy storage box. A heat exchanger is installed at either the air outlet or inlet of the housing. The energy storage box is connected to the water pump's inlet via a drain pipe. The water tank is connected to the water pump's inlet via an inlet pipe. The water pump's outlet is connected to the heat exchanger's inlet via an outlet pipe. The heat exchanger's outlet is connected to the water tank via a return pipe. A control element capable of controlling the on / off state of either the drain pipe or the inlet pipe is located at the intersection of the drain pipe and the inlet pipe. A water outlet valve assembly capable of supplying water to the energy storage box is located on the outlet pipe.

[0016] The difference in this structure lies in the control method of the control component. This control component is located at the junction of the drain pipe and the inlet pipe. When the drain pipe is open, the inlet pipe is blocked, and when the inlet pipe is open, the drain pipe is blocked. Similarly, the two water paths that transport water from the storage tank to the energy storage tank at night and water from the energy storage tank to the heat exchanger during the day are both powered by a single water pump, realizing two uses for one water pump, thereby reducing the number of water pumps and lowering equipment costs.

[0017] In the aforementioned energy storage air conditioner, the control component includes a reversing valve. The outlet of the reversing valve is connected to the inlet of the water pump, and the drain pipe and inlet pipe are respectively connected to the two inlets of the reversing valve. Water circuit switching is achieved through the reversing valve, resulting in a simple structure and high reliability.

[0018] An energy storage air conditioner includes a housing with air inlets and outlets on opposite side walls. A fan is installed at either the air inlet or outlet of the housing. An energy storage box, a main evaporator, a water tank, and a water pump are disposed inside the housing. The top of the energy storage box is open and located between the air inlet and outlet. The water tank is located below the energy storage box. The main evaporator is located inside the energy storage box. A heat exchanger is installed at either the air outlet or inlet of the housing. The bottom of the energy storage box is connected to the water tank via a drain pipe. The water tank is connected to the inlet of the water pump via a water inlet pipe. The outlet of the water pump is connected to the inlet of the heat exchanger via a water outlet pipe. The outlet of the heat exchanger is connected to the water tank via a return pipe. A water outlet valve assembly for supplying water to the energy storage box is provided on the water outlet pipe.

[0019] The melted ice water in the storage tank flows directly to the water tank through the drain pipe, keeping the ice in the storage tank constantly exposed. This allows airflow to act on the entire outer surface of the ice, improving the cooling effect. The water pump only draws water from the water tank. At night, when ice is being made, the outlet valve assembly opens, and the pump draws water from the water tank through the inlet pipe, then releases it into the storage tank through the outlet valve assembly. During the day, when cooling is needed, the outlet valve assembly closes, and the pump draws water from the water tank through the inlet pipe, then into the heat exchanger through the outlet pipe. This design allows both the nighttime water supply to the storage tank and the daytime water supply to the heat exchanger to be powered by a single pump, achieving two uses for one pump, thus reducing the number of pumps and lowering equipment costs.

[0020] Compared with existing technologies, this energy storage air conditioner has the following advantages:

[0021] 1. Due to the configuration of the control components and outlet valve assembly, both water lines that transport water from the storage tank to the energy storage tank at night and water from the energy storage tank to the heat exchanger during the day are powered by a single water pump, achieving two uses for one water pump, thereby reducing the number of water pumps and lowering equipment costs.

[0022] 2. Since a heat exchanger is also installed at the air outlet, 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 and improving the cooling effect.

[0023] 3. Since the ice water in the heat exchanger comes from the energy storage tank, utilizing the ice water obtained during ice making at night and the ice water after ice blocks melt during the day, the heat exchanger does not require the evaporator to perform high-energy-consuming refrigeration during the day, thus making it more energy-efficient.

[0024] 4. As the water in the storage tank is gradually extracted, the ice blocks are gradually exposed above the water surface, allowing the airflow to contact the entire outer surface of the ice blocks, thereby increasing the heat exchange area and improving the cooling effect.

[0036] 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.

[0037] Example 1:

[0038] like Figures 1 to 4 As shown, an energy storage air conditioner includes a rectangular casing 1. The side walls of the casing 1 may be thin-walled hollow structures, filled with insulation material. Air inlets 11 and outlets 12 are respectively provided on opposite side walls at the top of the casing 1, with the air inlets 11 and outlets 12 facing each other. A fan 2 is installed at the air inlet 11. An energy storage box 3, a main evaporator 4, a water tank 5, and a water pump 6 are provided inside the casing 1. The energy storage box 3 is fixedly installed in the upper part of the casing 1, and the water tank 5 is located below the energy storage box 3. The top of the energy storage box 3 is open and located between the air inlet 11 and the air outlet 12. The main evaporator 4 is fixed inside the energy storage box 3, and the top of the main evaporator 4 is slightly higher than the edge of the top opening of the energy storage box 3. A heat exchanger 7 is installed at the air outlet 12 of the casing 1. The housing 1 is also equipped with a drain pipe 31, an inlet pipe 51, an outlet pipe 71 and a return pipe 72. The water pump 6 is installed on the top surface of the water storage tank 5. The inlet end of the water pump 6 is connected to a three-way pipe 61. One end of the drain pipe 31 is connected to the bottom of the energy storage tank 3, and the other end is connected to one port of the three-way pipe 61. One end of the inlet pipe 51 extends downward into the water storage tank 5, and the other end is connected to the other port of the three-way pipe 61. Both the drain pipe 31 and the inlet pipe 51 are equipped with control components 8 that can control the on / off state. One end of the outlet pipe 71 is connected to the outlet of the water pump 6, and the other end is upward and connected to the inlet 74 of the heat exchanger 7. The return pipe 72 is vertically arranged, and the upper end of the return pipe 72 is connected to the outlet 75 of the heat exchanger 7, and the lower end is connected to the water storage tank 5. The lower end of the return pipe 72 can also be located above the water storage tank 5 and facing the water storage tank 5. An outlet valve assembly 9 that can send water to the energy storage tank 3 is provided on the outlet pipe 71.

[0039] Specifically, combined Figures 5 to 7As shown, the air outlet 12 is rectangular and faces horizontally to one side. The heat exchanger 7 includes multiple heat exchange tubes, all of which are S-shaped coiled and arranged side by side in a plate-like shape. The heat exchanger 7 is vertically installed and covers the air outlet 12. A distribution pipe 73 connected to the water outlet pipe 71 is also fixed inside the housing 1. The water inlets 74 of the multiple heat exchange tubes of the heat exchanger 7 are all connected to the distribution pipe 73. The water outlet valve assembly 9 includes a drain pipe 91 and an electric valve 92 installed on the drain pipe 91. One end of the drain pipe 91 is connected to the distribution pipe 73, and the other end extends horizontally to the top of the energy storage tank 3. The other end of the drain pipe 91 is bent downwards and faces the opening of the energy storage tank 3 below. The position of the other end of the drain pipe 91 is lower than the position of the distribution pipe 73, that is, lower than the position of the water inlet 74 of the heat exchanger 7. The control component 8 includes an electric valve 81 installed on the drain pipe 31 and the water inlet pipe 51 respectively.

[0040] A guide shell 13 is fixed at the air inlet 11 of the housing 1. The lower side plate of the guide shell 13 gradually slopes downward from the outside to the inside. The fan 2 is obliquely installed at the outer end port of the guide shell 13. The fan 2 is higher than the energy storage box 3 and faces the opening at the top of the energy storage box 3. The two side plates of the energy storage box 3 near the air inlet 11 and the air outlet 12 are both obliquely arranged, and the distance between the two side plates gradually increases from bottom to top. A guide plate 10 is also fixed inside the housing 1. The guide plate 10 is located above the energy storage box 3. The middle of the guide plate 10 is horizontally arranged and close to the top opening of the energy storage box 3. The two ends of the guide plate 10 are bent upward and obliquely, facing the air inlet 11 and the air outlet 12 respectively. Figure 8 As shown, the main evaporator 4 is formed by several refrigeration coils, and each refrigeration coil is coiled into a flat plate. The several flat refrigeration coils are arranged along the direction from the air inlet 11 to the air outlet 12, and are arranged in sequence at intervals along the width direction of the shell 1. A channel is formed between two adjacent refrigeration coils. There are gaps between the main evaporator 4 and the inner side and bottom of the energy storage box 3.

[0041] When ice storage is needed at night, the second electric valve 81 on the drain pipe 31 blocks the drain pipe 31, the second electric valve 81 on the inlet pipe 51 opens the inlet pipe 51, and the first electric valve 92 on the outlet pipe 91 opens the outlet pipe 91. When the water pump 6 is working, it can transport the water in the storage tank 5 from the inlet pipe 51 to the outlet pipe 71, and then discharge water into the energy storage tank 3 from the lower outlet pipe 91 port. The main evaporator 4 in the energy storage tank 3 makes ice. The ice blocks are smaller than the volume of the energy storage tank 3, and the ice blocks are submerged in cold water. When cooling is needed during the day, fan 2 is turned on. Airflow enters through air inlet 11 and exchanges heat with the surface of ice and water as it passes through the opening of storage tank 3, reducing the airflow temperature. At the same time, electric valve 2 81 on water inlet pipe 51 blocks water inlet pipe 51, electric valve 2 81 on drain pipe 31 opens drain pipe 31, and electric valve 1 92 on drain pipe 91 blocks drain pipe 91. Water pump 6 can transport the unfrozen ice water and the ice water after the ice has melted in storage tank 3 through drain pipe 31 to outlet pipe 71 and then into heat exchanger 7. The airflow cooled by ice can further exchange heat with heat exchanger 7 as it passes through air outlet 12, further reducing the airflow temperature. The water after heat exchange in heat exchanger 7 returns to water storage tank 5 through return pipe 72.

[0042] Example 2:

[0043] The structure of this energy storage air conditioner is basically the same as that of Embodiment 1. The difference is that an auxiliary evaporator is also provided in the water storage tank 5. During the daytime cooling, the ice water in the energy storage tank 3 is gradually drained, the second electric valve 81 of the drain pipe 31 is closed, and the second electric valve 81 of the inlet pipe 51 is opened, so that the ice water in the water storage tank 5 can be transported to the heat exchanger 7 for reuse. The auxiliary evaporator installed in the water storage tank 5 can cool the water in the water storage tank 5 to maintain the ice water supply of the heat exchanger 7 and ensure the cooling effect.

[0044] Example 3:

[0045] The structure of this energy storage air conditioner is basically the same as that of Embodiment 1, the difference being that... Figure 9 As shown, a control component 8 capable of controlling the on / off state of any one of the drain pipes 31 and 51 is provided at the junction of the drain pipe 31 and the inlet pipe 51. The control component 8 includes a reversing valve 82, the outlet of which is connected to the inlet of the water pump 6, and the drain pipe 31 and the inlet pipe 51 are respectively connected to the two inlets of the reversing valve 82.

[0046] Example 4:

[0047] The structure of this energy storage air conditioner is basically the same as that of Embodiment 1, the difference being that... Figure 10As shown, the bottom of the energy storage tank 3 is connected to the water storage tank 5 via a drain pipe 31. The inlet of the water pump 6 is connected to the water storage tank 5 only via an inlet pipe 51. The melted ice water in the energy storage tank 3 flows directly to the water storage tank 5 through the drain pipe 31, keeping the ice in the energy storage tank 3 constantly exposed and improving the cooling effect. The water pump 6 only draws water from the water storage tank 5. When making ice at night, the solenoid valve 92 of the drain pipe 91 opens the drain pipe 91, and the water pump 6 draws water from the water storage tank 5 through the inlet pipe 51, and then discharges water into the energy storage tank 3 through the outlet pipe 71. During the daytime cooling period, the solenoid valve 92 of the drain pipe 91 closes the drain pipe 91, and the water pump 6 draws water from the water storage tank 5 through the inlet pipe 51, and then enters the heat exchanger 7 through the outlet pipe 71.
