Detailed Description

In order that the above objects, features and advantages of the present invention can be more clearly understood, a more particular description of the invention will be rendered by reference to the appended drawings. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited by the specific embodiments disclosed below.

A refrigeration apparatus 100, a control method of the refrigeration apparatus, a control device 200 of the refrigeration apparatus, and a computer-readable storage medium according to some embodiments of the present invention are described below with reference to fig. 1 to 6.

Refrigeration appliances of the related art are generally provided with a refrigerant circulation system including a refrigerant circulation line, an evaporator, a condenser, a compressor and associated throttling and control elements. Wherein a refrigerant flows in the refrigerant circulation line to perform a reciprocating cycle among the evaporator, the condenser and the compressor, and thus to perform cooling.

The above-mentioned refrigeration apparatus in the related art has a problem in that it is bulky and occupies a large space because a plurality of refrigeration parts including a refrigerant circulation line, an evaporator, a condenser and a compressor are provided in the refrigeration apparatus. Therefore, in order to reduce the volume of the refrigeration apparatus, save the occupied space thereof, and enhance the user experience thereof, embodiments of the present invention provide the following refrigeration apparatus 100, a control method of the refrigeration apparatus, a control device 200 of the refrigeration apparatus, and a computer-readable storage medium.

Example 1:

as shown in fig. 1 and 2, the present embodiment provides a refrigerating apparatus 100 including: a refrigeration device body 110, a solid phase change medium 120, and a pressure applicator assembly 140. The refrigerating apparatus body 110 is provided with a refrigerating compartment 112. The solid phase change medium 120 is provided in the refrigerating apparatus body 110. Pressure application assembly 140 is adapted to switch between a pressure relief state and a pressure application state. The pressure applying assembly 140 drives the solid phase change medium 120 to be away from the refrigeration compartment 112 in the pressure applying state, and applies pressure to the solid phase change medium 120, so that the solid phase change medium 120 releases heat, and the pressure applying assembly 140 drives the solid phase change medium 120 to contact the refrigeration compartment 112 in the pressure relief state, and stops applying pressure to the solid phase change medium 120, so that the solid phase change medium 120 absorbs heat.

The refrigeration device 100 of the present embodiment may be specifically a refrigerator, freezer, or refrigerated display case. The refrigeration device body 110 includes a housing 116 adapted for thermal insulation. One or more refrigerated compartments 112 are provided within the housing 116, the refrigerated compartments 112 being used to contain and cryogenically store stored items. A door 118 is provided on the housing 116. The user opens the door 118 to access the stored items, and closes the door 118 to isolate the cooling compartment 112 from the external space.

The solid phase change medium 120 of the present embodiment cooperates with the pressing member 140 to perform a cooling function. In particular, the solid phase change medium 120 of the present embodiment can undergo a reversible phase change when subjected to a pressure, and absorb or dissipate heat accordingly during the phase change. Wherein the pressure applying assembly 140 applies pressure to the solid phase change medium 120 in a pressure relief state, the solid phase change medium 120 releases its stored heat and decreases in temperature when subjected to the pressure. The pressure application assembly 140 stops applying pressure to the solid phase change medium 120 in the pressure relief state, and releases the stored cold after the pressure applied to the solid phase change medium 120 is removed, so as to refrigerate the storage in the refrigeration apparatus 100.

Phase Change Material (PCM) refers to a Material that can absorb or release heat through a Change in physical properties. Such as: the water is used as a typical phase-change material and can be applied to refrigeration equipment such as a water-cooled air conditioner and the like, and the water stores cold in the solidification process and releases the cold in the melting process. For another example, paraffin is a typical phase change heat storage material, and has a wide application prospect in refrigeration equipment.

Compared with the phase-change material in the related art, one of the differences of the present embodiment is that the phase-change refrigeration medium of the present embodiment is a solid phase-change medium 120, which is kept in a solid state all the time during the phase change process. In addition, since the solid phase change medium 120 of the present embodiment remains solid during the phase change process, the structure is simple, which is not only convenient for manufacturing, but also convenient for installation and assembly.

It should be noted that the specific kind of the solid phase change medium 120 of the present embodiment can be selected by those skilled in the art according to actual needs.

For example, the solid phase change medium 120 of the present embodiment may be a Plastic Crystal Material (english name: Plastic Crystal Material), and the orientation of its molecules or structural units is switched between an ordered state and a disordered state to realize entropy change or enthalpy change comparable to the melting process. The pressing component 140 may induce a great clamping effect of the solid phase change medium 120, such as a plastic crystal material, by applying a small pressure, so that the solid phase change medium 120 releases heat. In thatIn some embodiments of this example, the solid phase change medium 120 is neopentyl glycol (chemical formula: (CH) ₃ ) ₂ C(CH ₂ OH) ₂ )。

For example again, the solid phase change medium 120 of the present embodiment may be specifically a shape memory alloy. The shape memory alloy releases heat after receiving pressure from pressure applicator assembly 140 and releases cold after pressure applicator assembly 140 is released. In some embodiments of this embodiment, the solid phase change medium 120 is at least one of the following: nickel-titanium alloy, iron-cobalt-nickel alloy, iron-palladium alloy, and nickel-cobalt alloy.

Compared with the related technology of refrigerating by using a circulating refrigerant, the embodiment does not need to provide components such as an evaporator, a condenser and a compressor with large volumes for the refrigerating equipment. Therefore, the refrigeration apparatus 100 of the present embodiment is small and light, and can save the occupied space. In addition, since the refrigeration apparatus 100 of the present embodiment does not need to adopt a complicated welding process to achieve the interconnection between the refrigerant circulation line and each refrigeration component, the refrigeration apparatus 100 of the present embodiment has a simple manufacturing process, a stable structure, a low cost and a high production efficiency. It should be noted that, the refrigeration apparatus 100 of the present embodiment does not need to compress the refrigerant by the compressor, and therefore, the refrigeration apparatus 100 of the present embodiment can avoid the problems of vibration and noise caused by the operation of the compressor, thereby improving the use experience of consumers.

It should be noted that, in the present embodiment, the pressure applying assembly 140 directly drives the solid phase-change medium 120 to move. When the solid phase-change medium 120 is used for refrigeration, the pressure applying component 140 drives the solid phase-change medium 120 to contact and cling to the refrigeration compartment 112, so that the solid phase-change medium 120 directly transmits cold to the refrigeration compartment 112. When the solid phase change medium 120 releases heat, the pressure applying assembly 140 drives the solid phase change medium 120 to be away from the refrigerating compartment 112, so as to prevent the heat dissipated by the solid phase change medium 120 from affecting the refrigerating compartment 112. Therefore, on the basis of realizing effective refrigeration, the heat exchange device and parts are omitted, so that the volume of the refrigeration equipment 100 is further reduced, and the production cost is reduced.

Example 2:

as shown in fig. 1 and 2, the present embodiment provides a refrigeration apparatus 100, and in addition to the technical features of embodiment 1 described above, the present embodiment further includes the following technical features.

The refrigerating apparatus body 110 further includes: and the solid phase change medium accommodating cavity 114, and the solid phase change medium accommodating cavity 114 is arranged adjacent to and spaced from the refrigerating compartment 112. Wherein the solid phase change medium 120 is disposed in the solid phase change medium accommodating chamber 114.

The solid phase-change medium accommodating cavity 114 of the embodiment is arranged on one side of the refrigerating compartment 112 far away from the door body 118, and is separated from the refrigerating compartment 112 by the second side wall 134. In the present embodiment, the solid phase-change medium 120 is disposed in the solid phase-change medium accommodating cavity 114 to prevent the heat generated by the solid phase-change medium 120 during heat release from affecting the stored substance in the refrigerating compartment 112.

Example 3:

as shown in fig. 1 and 2, the present embodiment provides a refrigeration apparatus 100, and in addition to the technical features of any of the above embodiments, the present embodiment further includes the following technical features.

The pressing member 140 is disposed in the solid phase change medium accommodating chamber 114, and at least a portion of the pressing member 140 surrounds an outer periphery of the solid phase change medium 120.

The pressure applying assembly 140 is disposed in the solid phase change medium accommodating chamber 114, so that the pressure applying assembly 140 provides reliable support for the solid phase change medium 120 and drives the solid phase change medium 120 to move stably. The pressing assembly 140 is wrapped on the outer surface of the solid phase change medium 120 to directly contact with the solid phase change medium 120 and perform contact heat exchange, so as to improve the heat dissipation and refrigeration effects of the solid phase change medium 120.

Example 4:

The refrigerating apparatus body 110 further includes: a first sidewall 132 and a second sidewall 134. The first sidewall 132 separates the solid phase-change medium accommodating chamber 114 and the external space of the refrigeration device body 110 from each other. Second sidewall 134 is disposed opposite first sidewall 132 and separates solid phase change medium receiving chamber 114 from refrigeration compartment 112. The pressure applying assembly 140 brings the solid phase change medium 120 into contact with the first sidewall 132 under the pressure applying condition, and the pressure applying assembly 140 brings the solid phase change medium 120 into contact with the second sidewall 134 under the pressure releasing condition.

In this embodiment, first sidewall 132 and second sidewall 134 are oppositely disposed and cooperate to collectively define at least a portion of solid phase change medium-containing cavity 114. The pressing component 140 brings the solid phase-change medium 120 into contact with and close to the first sidewall 132 in the pressing state, so that the solid phase-change medium 120 directly exchanges heat with the first sidewall 132. The pressurizing assembly 140 brings the solid phase-change medium 120 into contact with and clings to the second sidewall 134 under the pressure relief state, so that the solid phase-change medium 120 directly exchanges cold with the second sidewall 134. Therefore, in the embodiment, on the basis of realizing effective refrigeration, a heat exchange device and components are omitted, so that the volume of the refrigeration equipment 100 is further reduced, and the production cost of the refrigeration equipment is reduced.

Example 5:

the present embodiment provides a refrigeration apparatus 100, and in addition to the technical features of any of the above embodiments, further includes the following technical features.

At least a portion of the first sidewall 132 comprises a thermally conductive material; and/or at least a portion of the second sidewall 134 comprises a thermally conductive material.

The heat conductive material of the embodiment may be a metal heat conductive material such as a copper heat conductive material, an aluminum heat conductive material, a steel heat conductive material, or a heat conductive coating or a heat conductive plate material made of a polymer material and/or an inorganic polymer composite material.

The present embodiment uses a thermally conductive material to fabricate or configure the first sidewall 132 such that when the solid state phase change medium 120 contacts and abuts the first sidewall 132, the first sidewall 132 conductively dissipates heat from the solid state phase change medium 120. The second sidewall 134 is made of a heat conductive material or is configured to allow the second sidewall 134 to conductively dissipate the cold from the solid phase change medium 120 when the solid phase change medium 120 contacts and clings to the second sidewall 134. Therefore, the present embodiment can improve the heat dissipation effect and/or the cooling effect of the solid phase change medium 120.

Example 6:

as shown in fig. 3, the present embodiment provides a refrigeration apparatus 100, and in addition to the technical features of any one of the above embodiments, the present embodiment further includes the following technical features.

The pressing assembly 140 includes: a power section 142 and a pressing section 144. Wherein, the pressing part 144 applies pressure to the solid phase change medium 120 under the driving of the power part 142.

The power unit 142 of this embodiment provides power for the pressing unit 144, and the power unit 142 may be a driving device such as a motor, a hydraulic cylinder, and an air cylinder. The pressure part 144 may have a plate-shaped structure, which contacts and presses the solid phase change medium 120 by the driving of the power part 142 to apply pressure to the solid phase change medium 120. The number of the pressing portions 144 may be one or more, and may be disposed on one side of the solid phase change medium 120, or disposed on two opposite sides of the solid phase change medium 120, or may perform pressing on the solid phase change medium 120 from multiple sides of the solid phase change medium 120.

In the embodiment, the power part 142 drives the pressing part 144 to apply pressure to the solid-state phase-change medium 120, so as to ensure that the pressing assembly 140 can uniformly and stably apply force to the solid-state phase-change medium 120, thereby ensuring the heat dissipation effect of the solid-state phase-change medium 120.

Example 7:

At least a portion of the pressing portion 144 includes a thermally conductive material.

The present embodiment uses a heat conductive material to manufacture or configure the pressing portion 144, so that the pressing portion 144 can conduct and disperse heat or cold from the solid phase change medium 120. Therefore, the present embodiment can improve the heat dissipation effect and/or the cooling effect of the solid phase change medium 120.

Example 8:

The pressing assembly 140 includes: a drive section 146. The driving portion 146 is adapted to drive the solid phase-change medium 120 to move.

For example, the driving part 146 of the present embodiment includes a motor, a gear, and a rack. The motor rotates under the electric drive to drive the gear connected with the output shaft of the motor to rotate, and the gear is meshed with the rack, so that the rack is driven by the gear to do linear motion. The rack is connected to the solid phase change medium 120 so that the solid phase change medium 120 can be electrically driven into contact with or away from the refrigeration compartment 112.

Again by way of example, the drive portion 146 of the present embodiment includes a hydraulic cylinder and a link. The hydraulic oil cylinder drives the connecting rod to move under the driving of hydraulic oil, and the solid phase change medium 120 is connected with the connecting rod so as to move along with the connecting rod and contact with or be far away from the refrigerating chamber 112.

In the present embodiment, the driving portion 146 provides power for the movement of the solid phase-change medium 120, so as to ensure that the solid phase-change medium 120 can move smoothly and precisely.

Example 9:

as shown in fig. 4, the present embodiment provides a control method of a refrigeration apparatus, which is suitable for controlling the refrigeration apparatus 100 according to any embodiment of the present invention, and the control method of the refrigeration apparatus includes the following steps:

step S102, responding to a refrigeration instruction, controlling a pressure applying assembly to be switched to a pressure relief state so that a solid phase change medium contacts a refrigeration chamber and releases heat; and/or

And step S104, responding to the refrigeration stopping instruction, controlling the pressure applying component to be switched to a pressure applying state, so that the solid phase-change medium is far away from the refrigeration chamber and absorbs heat.

The present embodiment is used to control the refrigeration apparatus 100 according to any embodiment of the present invention. When the refrigeration device 100 is required to realize a refrigeration function, the present embodiment controls the pressure applying assembly 140 to release the pressure being applied to the solid-state phase-change medium 120, so that the solid-state phase-change medium 120 is phase-change refrigerated in an unstressed state. After the refrigeration device 100 completes or achieves the refrigeration target, the present embodiment controls the pressing assembly 140 to apply pressure to the positive solid phase-change medium 120 again, so that the solid phase-change medium 120 changes phase and releases heat in the stressed state. Thus, the present embodiment realizes low-temperature storage of the storage object due to the reversible phase change process of the solid phase change medium 120.

Example 10:

as shown in fig. 5, the present embodiment provides a control method of a refrigeration apparatus, which is suitable for controlling the refrigeration apparatus 100 according to any embodiment of the present invention. In addition to the technical features of any of the above embodiments, the present embodiment further includes the following technical features.

The control method of the refrigeration equipment further comprises the following steps:

step S202, responding to a first power-on instruction, controlling a pressure applying component to be switched to a pressure applying state so as to enable a solid phase change medium to be far away from a refrigerating chamber and release heat;

and step S204, judging that the continuous pressing time of the pressing assembly in the pressing state reaches a pressing time threshold, and controlling the pressing assembly to be switched to the pressure relief state so that the solid phase-change medium is in contact with the refrigerating chamber and absorbs heat.

It should be noted that the pressing time threshold of the present embodiment can be selected and adjusted by those skilled in the art according to actual needs, for example, the pressing time threshold can be set to 10 minutes, or 30 minutes, or 1 hour, etc.

A refrigeration device 100, such as a refrigerator, needs to have a refrigeration system including a solid state phase change medium 120 in a heat-releasing state when it is first powered up. At this time, the pressurizing assembly 140 applies pressure to the solid phase change medium 120, and may use a blower and a damper cooperating with each other to transfer heat dissipated from the solid phase change medium 120 to the outdoor space. When the time for which the refrigeration device 100 operates in the heat release state reaches a certain time, namely: when the pressure is applied for a threshold time, the pressure applying assembly 140 removes the pressure from the solid phase change medium 120, and the cold energy emitted from the solid phase change medium 120 can be sent to the refrigerating compartment 112 by using a fan and a damper cooperating with each other. Subsequently, when the temperature of the solid phase change medium 120 is close to the temperature of the cooling compartment 112, cooling is stopped and the cooling is switched to the heat release state again, and thus the cycle is repeated.

As shown in fig. 1 and 2, the refrigeration apparatus 100 of the present embodiment includes a refrigeration apparatus body 110, a solid phase-change medium 120, and a pressing assembly 140. The refrigerating apparatus body 110 includes a refrigerating compartment 112 and a solid phase change medium receiving chamber 114. The solid phase change medium accommodating chamber 114 is disposed adjacent to and spaced apart from the refrigerating compartment 112. A solid phase change medium 120 and a pressure applying assembly 140 are disposed in the solid phase change medium accommodating chamber 114. The first sidewall 132 and the second sidewall 134 of the refrigeration device body 110 together enclose a solid phase change medium receiving chamber 114. At least a portion of the first sidewall 132 and at least a portion of the second sidewall 134 comprise a thermally conductive material. The pressing assembly 140 includes: a power section 142, a pressure section 144, and a drive section 146. Wherein, the pressing part 144 applies pressure to the solid phase change medium 120 under the driving of the power part 142. The driving portion 146 is adapted to move the solid phase-change medium 120. At least a portion of pressure applicator 144 comprises a thermally conductive material.

The refrigeration apparatus 100 of the present embodiment is controlled by the following control method. When the refrigeration apparatus 100, such as a refrigerator, is first powered up, the refrigeration system is in a heat-releasing state, and the pressure application assembly 140 applies pressure to the solid phase-change medium 120, so that the solid phase-change medium 120 is away from the refrigeration compartment 112 and the solid phase-change medium 120 releases heat. When the continuous pressure application time of the pressure application component in the pressure application state reaches the pressure application time threshold, the heat release is stopped when the solid phase change medium 120 is close to the ambient temperature, at this time, the refrigeration system is switched to the refrigeration state, the pressure application component 140 applies force to the solid phase change medium 120, so that the solid phase change medium 120 contacts the refrigeration chamber 112 and absorbs heat, and when the temperature of the solid phase change medium 120 is close to the temperature of the refrigeration chamber 112, the refrigeration is stopped and the heat release state is switched again.

In summary, the embodiment of the invention has the following beneficial effects:

1. the present embodiment uses the solid phase-change medium 120 to refrigerate and realize low-temperature storage of stored objects, and does not need to provide bulky components such as an evaporator, a condenser and a compressor for the refrigeration equipment. Therefore, the refrigeration apparatus 100 of the present embodiment is small and light, and can save the occupied space.

2. Since the refrigeration equipment 100 of the present embodiment does not need to adopt a complex welding process to achieve the interconnection between the refrigerant circulation pipeline and each refrigeration component, the refrigeration equipment 100 of the present embodiment has a simple manufacturing process, a stable structure, a low cost and a high production efficiency.

3. The refrigerating apparatus 100 of the present embodiment can avoid the vibration and noise problems caused by the operation of the compressor, thereby improving the use experience of consumers.
