Description

Technical Field

[0001] The invention belongs to the technical field of air conditioners and relates to an energy storage air conditioner. Background Art

[0002] In order to encourage users to arrange electricity usage time reasonably and improve the utilization efficiency of power resources, the current peak-valley electricity policy is adopted. During the day, electricity users are concentrated, power supply is tight, and the charging standard is higher; at night, there are fewer electricity users, power supply is sufficient, and the charging standard is lower. Energy storage air conditioners are air conditioning equipment that uses energy to store energy at night and releases cold air during the day.

[0003] For example, a patent document (application number: 201320509709.5) discloses an automatic ice-making air conditioner, which includes a shell, an air outlet is provided on the upper part of the shell, and an air supply device is provided in the air outlet. A water tank and an ice-making device are provided in the shell, and the water tank is used to hold water for ice making. The top of the water tank 3 is open and arranged at the bottom of the shell. The ice-making device includes an ice storage tank, a pumping device, a guide pipe, an ice-making tank, an evaporator, a condenser, and a compressor. The ice storage tank is arranged on the water tank, and a filter hole is provided at the bottom of the ice storage tank to communicate with the opening of the water tank. A pumping device is provided at the bottom of the water tank, and a guide pipe is connected to the pumping device. The guide pipe can guide the water in the water tank to the ice-making tank at the top of the ice storage tank. The evaporator is arranged in the ice-making tank, and a grid is provided on the shell. At night, ice is made by the evaporator and poured into the ice storage tank. During the day, the fan runs, and the wind enters through the grid, and then enters through the air inlet, and then the air is cooled by ice cubes and sent out from the air outlet for cooling. However, the air flow speed is relatively fast, and the heat exchange with the ice cubes is not sufficient, which affects the refrigeration efficiency. Therefore, technical personnel in this field can easily think of increasing the lateral size of the ice storage tank to increase the air flow path, while improving the ice-making power and increasing the number of ice cubes, but this will also increase equipment costs and energy consumption. Summary of the invention

[0004] The purpose of the present invention is to address the above-mentioned problems in the prior art and to propose an energy storage air conditioner that can improve the cooling effect while reducing equipment cost and energy consumption.

[0005] The objective of the present invention can be achieved through the following technical solutions: an energy storage air conditioner, comprising a shell with an air inlet and an air outlet respectively opened on two opposite side walls, a fan installed at the air inlet or the air outlet of the shell, an energy storage box, a main evaporator, a water storage tank and a water pump are arranged in the shell, the top of the energy storage box is open and located between the air inlet and the air outlet, and is characterized in that the main evaporator is located in the energy storage box, a heat exchanger is installed at the air outlet or the air inlet of the shell, the energy storage box is connected with the water inlet end of the water pump through a downpipe, the water storage tank is connected with the water inlet end of the water pump through a water inlet pipe, the water outlet end of the water pump is connected with the water inlet of the heat exchanger through a water outlet pipe, the water outlet of the heat exchanger is connected with the water storage tank through a return pipe, a control member capable of controlling on and off is provided on the downpipe and the water inlet pipe, and a water outlet valve assembly capable of supplying water to the energy storage box is provided on the water outlet pipe.

[0006] The shell is made of thermal insulation material. The energy storage box, main evaporator and water pump are all fixed in the shell. 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 shell. The top opening of the energy storage box is located between the air inlet and outlet. Therefore, the air inlet, air outlet, fan and heat exchanger are all higher than the energy storage box. When ice making and energy storage are needed at night, the control part on the downpipe blocks the downpipe, the control part on the inlet pipe connects the inlet pipe, and the outlet valve assembly is opened. When the water pump is working, it can transport the water in the water storage tank from the inlet pipe to the outlet pipe, and then the lower outlet valve assembly releases water to the energy storage box. The main evaporator in the energy storage box makes ice. The ice cubes are smaller than the volume of the energy storage box, and the ice cubes are immersed in cold water. When cold air needs to be released during the day, the fan is turned on, and the air flows in from the air inlet and exchanges heat with the upper surface of the ice and the water surface when passing through the opening of the energy storage box, thereby reducing the temperature of the air flow. At the same time, the control component on the water inlet pipe blocks the water inlet pipe, the control component on the downpipe connects the downpipe, and the water outlet valve assembly is closed. The water pump can transport the unfrozen ice water in the energy storage box and the melted ice water from the downpipe to the water outlet pipe and then enter the heat exchanger. The air flow cooled by the ice can further exchange heat with the heat exchanger when passing through the air outlet, thereby further reducing the air flow temperature and improving the cooling effect.

[0007] Among them, through the setting of the control component and the water outlet valve assembly, the two water routes for transporting the water in the water storage tank to the energy storage tank at night and the water in the energy storage tank to the heat exchanger during the day are powered by a water pump, so that one water pump can be used for two purposes, thereby reducing the number of water pumps and reducing equipment costs. Furthermore, the ice water of the heat exchanger comes from the energy storage tank. The ice water obtained when making ice at night and the ice water after the ice cubes melt during the day are used. There is no need for the evaporator to perform high-energy refrigeration during the day, so it is more energy-efficient. In particular, as the water in the energy storage tank is gradually pumped out, the ice cubes are gradually exposed to the water surface, and the airflow can contact the entire outer surface of the ice cubes, thereby increasing the heat exchange area to improve the cooling effect.

[0008] In the above energy storage air conditioner, the water outlet valve assembly includes a drain pipe and an electric valve installed on the drain pipe, one end of the drain pipe is connected to the drain pipe, and the other end is located above the opening of the energy storage box, and the position height of the port at the other end of the drain pipe is lower than the position height of the water inlet of the heat exchanger. The drain pipe is slightly higher than the energy storage box, and the other end of the drain pipe is a water outlet port, which can discharge water into the energy storage box, especially the position height of the drain port is lower than the position height of the water inlet of the heat exchanger. By using the height difference, when the electric valve is opened during ice making at night, water is directly put into the energy storage box through the drain pipe and will not enter the heat exchanger at a higher position. When the electric valve is closed during cooling during the day, the water in the water outlet pipe can only enter the heat exchanger. This structure only needs one electric valve to realize the water path control in both directions of the energy storage box and the heat exchanger, reducing the number of electric valves and reducing equipment costs.

[0009] In the above energy storage air conditioner, the water inlet end of the water pump is connected to a three-way pipe, one end of the downpipe is connected to the bottom of the energy storage box, and the other end is connected to one end of the three-way pipe, one end of the inlet pipe extends into the water storage tank, and the other end is connected to another end of the three-way pipe, and the control component includes two electric valves installed on the downpipe and the inlet pipe respectively. The downpipe is connected to the bottom of the energy storage box, which can fully discharge the ice water in the energy storage box, so that the ice cubes are completely exposed, improving the cooling effect, and the downpipe and the inlet pipe are independently controlled by their own two electric valves to improve the operation reliability.

[0010] In the above energy storage air conditioner, the housing is fixed with a guide shell at the air inlet, the lower side plate of the guide shell gradually tilts downward from the outside to the inside, and the fan is obliquely installed at the outer end port of the guide shell and faces the opening at the top of the energy storage box. The fan is higher than the energy storage box, and the fan is obliquely arranged and faces the opening of the energy storage box, so the airflow can be directly blown to the ice cubes in the energy storage box under the action of the guide shell, reducing wind resistance and noise, and improving the cooling effect.

[0011] In the above energy storage air conditioner, the two side panels of the energy storage box near the air inlet and the air outlet are both inclined, and the spacing between the two side panels gradually increases from bottom to top. The main evaporator is formed by winding the refrigeration coil, and there is a gap 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 and the inner side and bottom of the energy storage box. Part of the airflow flows directly from above the ice and exchanges heat with the upper surface of the ice. Part of the 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, thereby improving the cooling effect.

[0012] In the above energy storage air conditioner, a guide plate is also fixed in the shell, and the guide plate is located above the energy storage box. The middle part of the guide plate is horizontally arranged and close to the top opening of the energy storage box. The two ends of the guide plate are bent upward into an inclined shape and face the air inlet and the air outlet respectively. The middle horizontal part of the guide plate forms a channel with the upper surface of the ice cube, and the air flow is guided downward through the inclined part of the guide plate near the air inlet end, so that the air flow fully acts on the ice cube, and then guided by the inclined part of the guide plate near the air outlet end, and blown out from the air outlet, reducing wind resistance and noise, and improving the cooling effect.

[0013] In the above energy storage air conditioner, the air outlet is rectangular, the heat exchanger is formed by coiling the heat exchange tube in an S shape into a plate, and the heat exchanger is vertically arranged and covers the air outlet, so that the airflow can fully exchange heat with the heat exchanger when passing through the air outlet, thereby improving the cooling effect.

[0014] In the above energy storage air conditioner, the water storage tank is located below the energy storage tank, and an auxiliary evaporator is also provided in the water storage tank. During daytime cooling, the ice water in the energy storage tank will gradually be exhausted, and it is difficult to continuously provide ice water to the heat exchanger. However, when the water returns to the water storage tank through the return pipe after heat exchange in the heat exchanger, the water temperature is still low. At this time, the electric valve 2 of the downpipe is closed, and the electric valve 2 of the inlet pipe is opened, so that the ice water in the water storage tank can 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 auxiliary evaporator is additionally provided in the water storage tank, which can cool the water in the water storage tank to maintain the ice water supply of the heat exchanger and ensure the cooling effect.

[0015] A storage type air conditioner comprises a shell with an air inlet and an air outlet respectively opened on two opposite side walls, a fan is installed at the air inlet or the air outlet of the shell, an energy storage box, a main evaporator, a water storage tank and a water pump are arranged in the shell, the top of the energy storage box is open and is located between the air inlet and the air outlet, and is characterized in that the main evaporator is located in the energy storage box, a heat exchanger is installed at the air outlet or the air inlet of the shell, the energy storage box is connected with the water inlet end of the water pump through a downpipe, the water storage tank is connected with the water inlet end of the water pump through a water inlet pipe, the water outlet end of the water pump is connected with the water inlet of the heat exchanger through a water outlet pipe, the water outlet of the heat exchanger is connected with the water storage tank through a return water pipe, a control component capable of controlling the on and off of any one of the downpipes and the water inlet pipe is provided at the intersection of the downpipe and the water inlet pipe, and a water outlet valve assembly capable of supplying water to the energy storage box is provided on the water outlet pipe.

[0016] The difference of this structure lies in the different control methods of the control component. The control component is located at the intersection of the downpipe and the water inlet pipe. When the downpipe is connected, the water inlet pipe is blocked, and when the water inlet pipe is connected, the downpipe is blocked. Similarly, the two water routes for transporting water from the water tank to the energy storage tank at night and from the energy storage tank to the heat exchanger during the day are both powered by one water pump, realizing two uses of one water pump, thereby reducing the number of water pumps and reducing equipment costs.

[0017] In the above energy storage air conditioner, the control element includes a reversing valve, the outlet of the reversing valve is connected to the water inlet of the water pump, and the downpipe and the water inlet pipe are respectively connected to the two inlets of the reversing valve. The water circuit is switched by the reversing valve, which has a simple structure and high reliability.

[0018] An energy storage air conditioner comprises a shell with an air inlet and an air outlet respectively opened on two opposite side walls, a fan is installed at the air inlet or the air outlet of the shell, an energy storage box, a main evaporator, a water storage tank and a water pump are arranged in the shell, the top of the energy storage box is open and located between the air inlet and the air outlet, and the water storage tank is located below the energy storage box, and is characterized in that the main evaporator is located in the energy storage box, a heat exchanger is installed at the air outlet or the air inlet of the shell, the bottom of the energy storage box is connected with the water storage tank through a downpipe, the water storage tank is connected with the water inlet end of the water pump through a water inlet pipe, the water outlet end of the water pump is connected with the water inlet of the heat exchanger through a water outlet pipe, the water outlet of the heat exchanger is connected with the water storage tank through a return pipe, and a water outlet valve assembly capable of supplying water to the energy storage tank is provided on the water outlet pipe.

[0019] The ice water from the melted ice in the energy storage tank flows directly to the water storage tank through the downpipe, so that the ice in the energy storage tank is always exposed, and the airflow can act on the entire outer surface of the ice, improving the cooling effect. The water pump only draws water from the water storage tank. When making ice at night, the water outlet valve assembly is opened, and the water pump draws water from the water storage tank through the water inlet pipe, and then discharges water to the energy storage tank through the water outlet pipe by the water outlet valve assembly. During daytime cooling, the water outlet valve assembly is closed, and the water pump draws water from the water storage tank through the water inlet pipe, and then enters the heat exchanger through the water outlet pipe. Through the setting of the water outlet valve assembly, the two water routes that transport water from the water storage tank to the energy storage tank at night and transport water from the water storage tank to the heat exchanger during the day are powered by one water pump, so that one water pump can be used for two purposes, thereby reducing the number of water pumps and reducing equipment costs.

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

[0021] 1. Due to the setting of the control component and the water outlet valve assembly, the two water routes for transporting water from the water storage tank to the energy storage tank at night and from the energy storage tank to the heat exchanger during the day are both powered by one water pump, achieving two uses of one water pump, thereby reducing the number of water pumps and reducing equipment costs.

[0022] 2. Since a heat exchanger is also provided at the air outlet, the airflow cooled by ice cubes 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 of the heat exchanger comes from the energy storage tank, using the ice water obtained from ice making at night and the ice water after the ice cubes melted during the day, the heat exchanger does not need an evaporator to perform high-energy cooling during the day, so it is more energy-efficient.

[0024] 4. As the water in the energy storage box is gradually pumped out, the ice cubes are gradually exposed to the water surface, and the airflow can contact the entire outer surface of the ice cubes, thereby increasing the heat exchange area and improving the refrigeration effect.

DETAILED DESCRIPTION

[0036] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0037] Embodiment 1:

[0038] like Figures 1 to 4 As shown, an energy storage air conditioner includes a rectangular shell 1, the side wall of the shell 1 can be a thin-walled hollow structure, and the interior is filled with heat-insulating materials. An air inlet 11 and an air outlet 12 are respectively opened on the opposite side walls of the upper part of the shell 1, and the air inlet 11 is opposite to the air outlet 12. A fan 2 is installed at the position of the air inlet 11. An energy storage box 3, a main evaporator 4, a water storage tank 5 and a water pump 6 are arranged in the shell 1. The energy storage box 3 is fixedly arranged in the upper part of the shell 1, and the water storage 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 in the energy storage box 3, and the top of the main evaporator 4 is slightly higher than the top opening edge of the energy storage box 3. The shell 1 is equipped with a heat exchanger 7 at the air outlet 12. A downpipe 31, a water inlet pipe 51, a water outlet pipe 71 and a water return pipe 72 are also provided in the shell 1. The water pump 6 is arranged on the top surface of the water storage tank 5. The water inlet end of the water pump 6 is connected to a tee pipe 61. One end of the downpipe 31 is connected to the bottom of the energy storage tank 3, and the other end is connected to one port of the tee pipe 61. One end of the water inlet pipe 51 extends downward into the water storage tank 5, and the other end is connected to the other port of the tee pipe 61. Control parts 8 that can control on and off are provided on the downpipe 31 and the water inlet pipe 51. One end of the water outlet pipe 71 is connected to the water outlet end of the water pump 6, and the other end is upward and connected to the water 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 water 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 face the water storage tank 5. A water outlet valve assembly 9 is provided on the water outlet pipe 71, which can deliver water to the energy storage tank 3.

[0039] Specifically, combined Figures 5 to 7As shown, the air outlet 12 is rectangular and horizontally faces one side. The heat exchanger 7 includes a plurality of heat exchange tubes, which are all coiled in an S shape and arranged in a plate shape. The heat exchanger 7 is vertically arranged and covers the air outlet 12. A distribution pipe 73 connected to the water outlet pipe 71 is also fixed in the housing 1. The water inlets 74 of the plurality of 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 1 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 box 3. The other end of the drain pipe 91 is bent downward and faces the opening of the energy storage box 3 below. The position height of the port at the other end of the drain pipe 91 is lower than the position height of the distribution pipe 73, that is, lower than the position height of the water inlet 74 of the heat exchanger 7. The control component 8 includes an electric valve 2 81 installed on the downpipe 31 and the water inlet pipe 51 respectively.

[0040] A guide shell 13 is fixed at the air inlet 11 of the shell 1. The lower side plate of the guide shell 13 gradually tilts downward from the outside to the inside. The fan 2 is installed obliquely 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 close to the air inlet 11 and the air outlet 12 are both inclined, and the distance between the two side plates gradually increases from bottom to top. A guide plate 10 is also fixed in the shell 1. The guide plate 10 is located above the energy storage box 3. The middle part 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 into an inclined shape and face the air inlet 11 and the air outlet 12 respectively. Figure 8 As shown, the main evaporator 4 is formed by winding a plurality of refrigeration coils, and each refrigeration coil is wound into a flat plate shape, and a plurality of flat plate-shaped refrigeration coils are arranged along the direction from the air inlet 11 to the air outlet 12, and are arranged in sequence along the width direction of the shell 1. A channel is formed between two adjacent refrigeration coils, and there is a gap between the main evaporator 4 and the inner side surface and bottom surface of the energy storage box 3.

[0041] When ice making and energy storage are needed at night, the electric valve 2 81 on the downpipe 31 blocks the downpipe 31, the electric valve 2 81 on the inlet pipe 51 connects the inlet pipe 51, and the electric valve 1 92 on the drain pipe 91 connects the drain pipe 91. When the water pump 6 is working, the water in the water storage tank 5 can be transported from the inlet pipe 51 to the outlet pipe 71, and then the water is discharged to the energy storage tank 3 from the lower port of the drain pipe 91. The main evaporator 4 in the energy storage tank 3 makes ice, and the ice cubes are smaller than the volume of the energy storage tank 3, and the ice cubes are immersed in cold water. When it is necessary to release cold air during the day, the fan 2 is turned on, and the air flow enters through the air inlet 11 and exchanges heat with the upper surface of the ice and the water surface when passing through the opening of the energy storage box 3, thereby reducing the temperature of the air flow. At the same time, the electric valve 2 81 on the water inlet pipe 51 blocks the water inlet pipe 51, the electric valve 2 81 on the downpipe 31 connects the downpipe 31, and the electric valve 1 92 on the drain pipe 91 blocks the drain pipe 91. The water pump 6 can transport the unfrozen ice water in the energy storage box 3 and the melted ice water from the downpipe 31 to the outlet pipe 71 and then enter the heat exchanger 7. The air flow cooled by the ice can further exchange heat with the heat exchanger 7 when passing through the air outlet 12, thereby further reducing the air flow temperature. The water after heat exchange in the heat exchanger 7 returns to the water storage tank 5 through the return pipe 72.

[0042] Embodiment 2:

[0043] The structure of the energy storage air conditioner is basically the same as that of the first embodiment, except that an auxiliary evaporator is further provided in the water storage tank 5. During daytime cooling, the ice water in the energy storage tank 3 is gradually discharged, the electric valve 2 81 of the downpipe 31 is closed, and the electric valve 2 81 of the water 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 provided in the water storage tank 5 can cool the water in the water storage tank 5 to maintain the ice water supply to the heat exchanger 7 and ensure the cooling effect.

[0044] Embodiment three:

[0045] The structure of the energy storage air conditioner is basically the same as that of the first embodiment. Fig. 9 As shown, at the intersection of the downpipe 31 and the water inlet pipe 51, a control component 8 capable of controlling the on and off of any one of them is provided. The control component 8 includes a reversing valve 82, the outlet of the reversing valve 82 is connected to the water inlet end of the water pump 6, and the downpipe 31 and the water inlet pipe 51 are respectively connected to the two inlets of the reversing valve 82.

[0046] Embodiment 4:

[0047] The structure of the energy storage air conditioner is basically the same as that of the first embodiment. Fig.10As shown, the bottom of the energy storage tank 3 is connected to the water storage tank 5 through the downpipe 31, and the water inlet end of the water pump 6 is connected to the water storage tank 5 only through the inlet pipe 51. The ice water melted from the ice in the energy storage tank 3 flows directly to the water storage tank 5 through the downpipe 31, so that the ice in the energy storage tank 3 is always exposed, improving the refrigeration effect, and the water pump 6 only pumps water from the water storage tank 5. When making ice at night, the electric valve 1 92 of the drain pipe 91 conducts the drain pipe 91, and the water pump 6 pumps water from the water storage tank 5 through the inlet pipe 51, and discharges water from the drain pipe 91 to the energy storage tank 3 through the outlet pipe 71. During cooling during the day, the electric valve 1 92 of the drain pipe 91 blocks the drain pipe 91, and the water pump 6 pumps water from the water storage tank 5 through the inlet pipe 51, and enters the heat exchanger 7 through the outlet pipe 71.
