[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.
[0024] See also Figure 1 The utility model discloses a phase-change energy storage air conditioner, comprising a housing 10 and a heat exchange assembly. The housing 10 has a first installation cavity 11 and a second installation cavity 12. An energy storage box 13 is arranged in the second installation cavity 12. The energy storage box 13 has a phase change material layer 132. The phase change material layer 132 can be used to store energy. The energy storage box 13 has a conduction port and a lead-out port. Specifically, a fluid medium can be introduced into the energy storage box 13 through the conduction port, and then the phase change material layer 132 exchanges heat with the fluid medium. The lead-out port is used to guide the fluid medium after heat exchange to be discharged out of the second installation cavity 12.
[0025] In addition, the heat exchange component includes a first heat exchange element 20 and a second heat exchange element 21. The first heat exchange element 20 is installed in the first installation cavity 11 and is connected to the outside. The first heat exchange element 20 is used to exchange heat with the outside, and the second heat exchange element 21 is installed in the second installation cavity 12. One end of the second heat exchange element 21 is connected to the first heat exchange element 20, and the other end of the second heat exchange element 21 is connected to the energy storage box 13, and is used to transmit energy to the energy storage box 13. The energy storage box 13 stores energy through the phase change material layer 132.
[0026] On the basis of the above structure, during assembly, the first heat exchanger 20 and the second heat exchanger 21 are respectively installed in the first installation cavity 11 and the second installation cavity 12. Specifically, one end of the first heat exchanger 20 is connected to the outside and is used to exchange heat with the indoor air to achieve the effect of regulating the indoor temperature, while the second heat exchanger 21 can be connected to the other end of the first heat exchanger 20, so that the heat or cold converted by the first heat exchanger 20 in the external heat exchange process can be discharged into the second heat exchanger 21, and then the second heat exchanger 21 transports the converted heat or cold to the energy storage box 13 for storage, without the need to discharge it to the outside, and without the need to install an external unit to release the converted energy, thereby reducing the installation space of the entire equipment.
[0027] Specifically, after the heat or cold is discharged to the energy storage box 13, the phase change material layer 132 in the energy storage box 13 can store the heat or cold. During assembly, the conducting port on the energy storage box 13 can be connected to the external water circuit to guide the external water circuit into the energy storage box 13. At this time, the phase change material layer 132 in the energy storage box 13 can cool the fluid medium (specifically, domestic water) introduced into the energy storage box 13 through the cold energy stored in itself, and then communicate with the external water pipeline through the outlet, so as to guide the cooled fluid medium out of the second installation cavity 12 through the outlet for external domestic water use;
[0028] Similarly, when the user needs to use hot water, the heat energy stored in the phase change material layer 132 in the energy storage box 13 can be used to heat the introduced fluid medium, so that the water discharged from the outlet is hot water for direct use by the user. In this way, the heat energy or cold energy converted in the heat exchange process of the heat exchange component is recycled, and the user does not need to purchase additional equipment to heat or cool domestic water, which saves resources to a certain extent. At the same time, there is no need to install an additional external unit to release the converted heat or cold energy, which indirectly reduces the volume of the entire equipment, saves installation space, and facilitates user installation and maintenance.
[0029] More specifically, when the second heat exchange element 21 is assembled, a sealed shell can be sleeved on the outer periphery (that is, a sealed box (such as a heat exchange box) or a shell is set in the second installation cavity to install the second heat exchange element), and an inlet and an outlet are set on the shell. The specific inlet can be connected to the outside to introduce a heat exchange medium (such as oil crystal, water or gas, etc.) into the shell, and then connected to the energy storage box 13 through a heat conduction pipe (such as a metal pipe such as a copper pipe or an aluminum pipe). One end of the specific heat conduction pipe can be installed at the outlet, and the other end can extend and penetrate the entire phase change material layer 132. Finally, after penetrating the phase change material layer 132, The heat exchanger 21 is extended into the outer shell of the second heat exchanger 21 to form a closed loop, and a water pump is installed on the heat conduction pipe to drive the heat exchange medium flowing around the second heat exchanger 21 to repeatedly flow between the second heat exchanger 21 and the phase change material layer 132, so that the energy converted by the second heat exchanger 21 can be repeatedly circulated and transferred to the phase change material layer 132 and stored for recycling. At this time, it is only necessary to introduce domestic water into the energy storage box 20 through the conduction port, and the energy stored in the phase change material layer 132 can directly heat or cool the domestic water, and then be exported to the outside through the export port for direct use, so that the energy is recycled;
[0030] Of course, when the heat exchange medium used by the second heat exchanger 21 to transfer energy is water, the external waterway (such as a water tank or other pipeline) can be connected to the outer shell connected to the second heat exchanger 21 and the conducting port on the energy storage box respectively. At this time, the external domestic water can be directly introduced into the second heat exchanger 21 first, so that the energy generated by the heat exchange process of the second heat exchanger 21 can be transferred to the domestic water, so as to transport the domestic water as the heat exchange medium to the energy storage box 13. At this time, the domestic water in the energy storage box 13 can be directly discharged through the outlet for external use, or it can be discharged to the external waterway through the conducting port after the energy is transferred to the phase change material layer 132 and circulated back to the second heat exchanger 21 for recycling again. The specific setting method can be set according to actual needs.
[0031] It should be noted that after the fluid medium in the energy storage box 13 that is heated or cooled by the phase change material layer 132 is discharged to the outside through the outlet, a drain pipe 62 can be set at the outlet, and the drain pipe 62 can be directly connected to the domestic water pipeline in the kitchen or bathroom, so that the user can use water directly; an additional temperature difference power generation device can also be set outside the shell 10, and a drain pipe 62 is added to conduct with the temperature difference power generation device, so that the discharged hot water or cold water can generate a temperature difference at both ends of the temperature difference power generation device, thereby generating electricity, thereby making full use of resources.
[0032] In addition, a water pipe or conduit or other pipeline may be provided at the conducting port on the energy storage box 13 to communicate with an external water tank or water pipe, or a water tank may be provided inside the shell 10 to store domestic water, so that a fluid medium is introduced into the energy storage box 13 from time to time to be heated or cooled by the phase change material layer 132 for water use by users.
[0033] Preferably, in the present embodiment, the phase change material layer 132 is selected from paraffin, acetic acid, crystalline hydrated salts, molten salts, paraffin, etc. During assembly, the phase change material can be pumped out by a pump in liquid state to fill the energy storage box 13. Of course, it can also be filled in the form of solid powder, depending on the characteristics of the actual material.
[0034] In addition, in this embodiment, the first heat exchange element 20 is a plate heat exchanger or a tube heat exchanger, and the second heat exchange element 21 is a fin heat exchanger.
[0035] Furthermore, a liquid storage tank 14 is provided, one end of which is connected to the outside, and the other end of which is connected to the conducting port. The liquid storage tank 14 is used to guide the fluid medium to be introduced into the energy storage tank 13 through the conducting port.
[0036] On the basis of this structure, in this embodiment, the liquid storage tank 14 can be arranged in the second installation cavity 12, and can also be installed on the side of the shell 10 close to the second installation cavity 12. The fluid medium is filled through the liquid storage tank 14. Specifically, one end of the liquid storage tank 14 can be connected to the external water circuit, and the other end of the liquid storage tank 14 can be connected to the conduction port on the energy storage tank 13. In this way, the water in the external water circuit can be first introduced into the liquid storage tank 14 for storage. When the user needs water, the water in the liquid storage tank 14 can be introduced into the energy storage tank 13 for heating or cooling, so as to be directly used by the user.
[0037] In the utility model, a liquid storage tank 14 is arranged inside the housing 10 to pre-store the fluid medium, so that water can still be available when there is no water or water shortage outside, and the structure is more practical.
[0038] Furthermore, a liquid inlet interface and a liquid passage interface are provided on the liquid storage tank 14, and a first conduit 60 is penetrated at the liquid inlet interface, and one end of the first conduit 60 extends to the outside of the shell 10 to communicate with the external waterway, so that the external fluid medium (that is, domestic water) can be introduced into the liquid storage tank 14 for storage through the first conduit 60, and then a second conduit 61 is provided at the liquid passage interface, and the second conduit 61 is communicated with the conduction port on the energy storage tank 13, so that the fluid medium in the liquid storage tank 14 can flow into the energy storage tank 13.
[0039] Preferably, the first conduit 60 and the second conduit 61 can both use existing drain pipes 62 or guide pipes, and the liquid inlet interface and the liquid flow interface can be integrally formed or mechanically cut on the liquid storage tank 14, and a hose connector, a hard pipe connector or a quick-connect connector with good sealing properties can be used at the liquid inlet interface and the liquid flow interface to connect the first conduit 60 and the second conduit 61 to reduce the risk of leakage of the liquid storage tank 14.
[0040] Furthermore, the energy storage box 13 has two energy storage chambers 131, one of which is used to store cold and the other is used to store heat. Phase change material layers 132 are provided in the two energy storage chambers 131, and the two phase change material layers 132 are arranged along the inner wall of the energy storage chamber 131. A conduction port and a lead-out port are provided on the two energy storage chambers 131, and the two conduction ports are connected to the liquid storage tank 14, and the two lead-out ports are connected to the outside.
[0041] On the basis of the above structure, the energy storage box 13 in the present embodiment has two energy storage chambers 131. The two energy storage chambers 131 can be formed by setting a baffle in the energy storage box 13 to divide the box body into two, or by adding two box bodies in the energy storage box 13. Phase change material layers 132 are respectively provided in the two energy storage chambers. When the first heat exchange element 20 is heating, the heat energy converted in the heating process can be discharged by the second heat exchange element 21 to one of the energy storage chambers 131 and stored in one of the phase change material layers 132. When the first heat exchange element 20 is cooling, the heat energy generated in the cooling process can be discharged by the second heat exchange element 21 to the other energy storage chamber 131 and stored in the phase change material layer 132. The heat energy or cold energy can be stored in the two energy storage chambers 131 respectively. In this way, when the user needs to use hot water and cold water, the water can be taken separately, which is more practical.
[0042] In addition, since different phase change materials have different phase change temperatures and thermal properties, each phase change material has a specific phase change temperature, that is, at this temperature the material changes from one physical state to another, and the storage effect and transmission effect of heat energy and cold energy are different. Therefore, in this embodiment, two different energy storage cavities 131 are used to respectively set phase change material layers 132, so that heat energy or cold energy can be stored respectively through different phase change material layers 132, and the heat exchange effect is better. One of the phase change material layers 132 can specifically select phase change materials with good energy storage and cold energy transfer effects, such as paraffin, acetic acid and other organic substances, and the material of the other phase change material layer 132 can be a phase change material with good heat storage and heat energy transfer effects, which can specifically be crystalline hydrated salts, molten salts, paraffin, etc.
[0043] Furthermore, a flow channel 133 is provided in each of the two energy storage chambers 131, and one end of the two flow channels 133 is respectively connected to the two conduction ports, and the other end of the two flow channels 133 is respectively connected to the two outlets, so that the fluid medium is introduced through the flow channels 133. Specifically, the flow channels 133 can be formed by a conduit made of a heat-conducting material (such as a heat-conducting metal such as copper or aluminum), and the phase change material layer 132 can be coated on the periphery of the flow channels 133 so that the energy stored therein can be transferred to the periphery of the flow channels 133, so that the fluid medium in the flow channels 133 can exchange heat.
[0044] During specific assembly, drain pipes 62 are provided at the two outlets. Both drain pipes 62 can extend out of the second installation cavity 12 to be connected with the external water channel, and water outlet taps 70 are respectively provided on the two drain pipes 62 to control the discharge of the fluid medium in the drain pipes 62 through the water outlet taps 70, so that the structure is more practical.
[0045] Furthermore, the utility model also includes a heat exchange box 15, one end of the heat exchange box 15 is respectively connected to the two energy storage chambers 131 in the energy storage box 13, and the other end of the heat exchange box 15 is connected to the liquid storage tank 14, so that the fluid medium in the liquid storage tank 15 is introduced into the heat exchange box 15 for use as a heat exchange medium, and then the second heat exchange element 21 is installed in the heat exchange box 15, and the second heat exchange element 21 is used to exchange heat with the heat exchange medium (that is, the above-mentioned fluid medium) in the heat exchange box 15.
[0046] Specifically, during assembly, the second heat exchange component 21 is installed inside the heat exchange box 15, and then the two ends of the heat exchange box 15 are connected to the liquid storage tank 14 and the two energy storage chambers 131 respectively. At this time, the fluid medium in the liquid storage tank 14 can be first introduced into the heat exchange box 15 as a heat exchange medium, and the energy flow released by the second heat exchange component 21 is transferred to the two energy storage chambers 131, stored in the phase change material layer 132, and finally returned to the liquid storage tank 14 through the conducting ports on the two energy storage chambers 131, so that the fluid medium stored in the liquid storage tank 14 can be used as a heat exchange medium to repeatedly flow in the heat exchange box 15, the energy storage tank 13 and the liquid storage tank 14 to transfer energy, and can be returned to the liquid storage tank 14 for recycling.
[0047] It should be noted that, in the present embodiment, the fluid medium introduced into the liquid storage tank 14 is domestic water. At this time, the domestic water can be introduced into the heat exchange box 15 as a heat exchange medium for heat exchange, and can also be transported to the energy storage chamber 131 after heat exchange and then directly exported through the outlet for direct external use. There is no need to add new pipelines to introduce new heat exchange medium into the heat exchange box 15 for heat exchange, thereby simplifying the structure of the entire equipment. In addition, energy is transferred through the fluid medium, and the heat exchange effect is better. Due to the compressibility of the fluid, it is not necessary to occupy a large installation space during installation, thereby reducing the volume of the entire structure and facilitating later installation and maintenance.
[0048] Furthermore, a steering valve 80 is provided between the heat exchange box 15 and the energy storage box 13. One end of the steering valve 80 can be connected to the heat exchange box 15 through a pipeline, and the other end of the steering valve 80 can also be connected to the two energy storage chambers 131 respectively through two pipelines, so as to control the flow direction of the heat exchange medium in the heat exchange box 15 through the steering valve 80. In this way, the heat exchange medium flowing in the heat exchange box 15 can flow to different energy storage chambers 131 when carrying heat energy or cold energy.
[0049] Specifically, a temperature sensor or detector may be provided in the heat exchange box 15 to transmit data collected by the temperature sensor and other equipment to the background in real time, so as to detect the temperature of the fluid medium in real time, so that the temperature can be transmitted to different energy storage chambers 131 for storage under different temperature conditions.
[0050] Preferably, the steering valve 80 can be a valve body that can be used to switch the water path, such as a two-way valve, a three-way valve or a four-way valve. The control of the valve of the steering valve 80 can be manually operated by an operator or intelligently operated by setting a control program.
[0051] Furthermore, an air outlet 16 is provided on the shell 10, and the air outlet 16 is connected with the first installation cavity 11, and at least two guide fans 40 are arranged in the first installation cavity 11, one of the guide fans 40 is arranged on one side of the first heat exchange component 20 and is used to guide the airflow to the air outlet 16, and the other guide fan 40 is located at the air outlet 16 and is used to guide the airflow in the first installation cavity 11 to be discharged through the air outlet 16.

The heat or cold energy in the first installation cavity 11 is discharged by at least two fans, and the energy transmission effect is better.
[0053] Preferably, the guide fan 40 can be formed by an exhaust fan or an exhaust fan, and can be set to two, three or more according to the size of the space inside the first installation cavity 11, so that the heat or cold in the first installation cavity 11 can be transported to the indoor environment more quickly.
[0054] Furthermore, the utility model is also provided with a compressor 30 and a water pump 50 . The two ends of the compressor 30 are respectively connected to the first heat exchange element 20 and the second heat exchange element 21 , and the water pump 50 can drive the fluid medium in the energy storage box 13 to flow.
