Description

Technical Field

[0001] The present invention relates to a novel solid refrigeration field, in particular to an anti-phase cold and hot working medium integrated system based on elasto-caloric effect. Background Art

[0002] The proportion of refrigeration energy consumption in global energy consumption is increasing year by year, becoming an important part that cannot be ignored. At present, the mainstream refrigeration technology widely used in the world is still vapor compression refrigeration technology. However, this technology is limited by the principles of thermodynamics and its peak refrigeration efficiency can only reach 60%. What is more serious is that traditional Freon refrigerants pose a serious threat to the ozone layer and aggravate the problem of global climate change. Therefore, exploring and developing more environmentally friendly and efficient refrigeration technology has become an important issue that needs to be urgently solved in the global refrigeration field.

[0003] In the above background, elastic thermal refrigeration technology has stood out with its unique advantages and has become the focus of research by various countries. It uses pure natural solid working fluids with no global warming potential (GWP), no ozone depletion potential (ODP), no flammability, and no toxicity, and is an environmentally friendly refrigeration technology. Elastic thermal refrigeration technology is considered to be an environmentally friendly, efficient, and energy-saving refrigeration technology with great application potential. This technology can not only achieve a refrigeration efficiency of up to 65%, significantly surpassing the upper limit of traditional vapor compression refrigeration technology, but also demonstrates extraordinary strength in cost control. Its raw materials are widely available and inexpensive, and there is no environmental pollution. However, although the current elastic thermal refrigeration technology has successfully realized the stretching and contraction operation mode using servo motors, such as the Chinese patent application No. 202010457171.2, which discloses a cold and heat cogeneration device based on the elastic thermal effect, the generated cold / heat is only taken away by cold / heat conduction or convection, resulting in the cold / heat generated in a cooling / heating stage cannot be discharged in time, and in the next heating / cooling stage, the cold / heat is mixed, resulting in a large loss of cold / heat. For example, the applicant's prior patent application CN202411084193.3 uses the form of continuously generating cold / hot air to take away the cold / heat. Due to the large volume of the cavity, the wind direction is not accurately enough to point to the elastic thermal material, the cold / heat cannot be completely eliminated, and the convection heat transfer coefficient is small, resulting in low refrigeration efficiency. If it is eliminated through heat conduction, due to the thermal resistance of the heat-conducting material, there will be a large loss of cold / heat. Summary of the invention

[0004] The purpose of the present invention is to provide an anti-phase hot and cold working fluid integrated system based on the caloric effect. The system uses fluid working fluid as the heat exchange medium, and uses high-pressure working fluid to drive the slider to move, so that the caloric material stretches to heat and contracts to cool, and removes the cold / heat through convection heat exchange. The heat exchange efficiency is high, and the cold / hot working fluid can be continuously produced, and the cold / heat can be discharged in time to improve the system performance. In addition, the system can realize the series and parallel setting of multiple modules, which is convenient to control and can provide heat exchange of higher or lower temperatures and more working fluids.

[0006] Furthermore, a temperature sensor is provided at the hot working fluid outlet. When the slider moves to the hot working fluid outlet, hot working fluid is extracted from the hot working fluid outlet. When the temperature sensor detects that the temperature is equal to the original working fluid temperature, the extraction of hot working fluid is stopped. When the high-pressure working fluid flows into the pressure chamber, cold working fluid is extracted from the side with low pressure in the pressure chamber.

In this process, the elastic thermoplastic material in the left chamber releases heat to the fluid, and at the same time, drives the elastic thermoplastic material in the right chamber to gradually shrink, and the material changes from martensite to austenite, and the elastic thermoplastic material in the right chamber absorbs heat from the fluid; when the slider moves to the hot working medium outlet, the hot electric valve opens, and the working medium in the left chamber flows out from the hot working medium outlet, taking away heat and relieving pressure. Under the push of the slider, the working medium in the right chamber flows into the cold working medium outflow pipeline through the control of the third electric three-way valve, taking away cold; In the lower pressure chamber, when the high-pressure original temperature working fluid enters from the right working fluid flow port of the lower pressure chamber, the slider moves to the left under the driving effect of the pressure in the right chamber, driving the elastic thermoplastic material 8 in the right chamber to gradually stretch, and the material changes from austenite to martensite. During this process, the elastic thermoplastic material in the right chamber releases heat to the fluid; at the same time, it drives the elastic thermoplastic material in the left chamber to gradually shrink, and the material changes from martensite to austenite, and the elastic thermoplastic material in the left chamber absorbs heat from the fluid; when the slider moves to the hot working fluid outlet, the hot electric valve opens, and the working fluid in the right chamber flows out from the hot working fluid outlet, taking away heat and releasing pressure, and the working fluid in the left chamber, driven by the slider, flows into the cold working fluid outflow pipeline through the control of the second electric three-way valve, taking away cold; The working fluid enters the upper pressure chamber from the right and enters the lower pressure chamber from the left mode: in the upper and lower pressure chambers, when the temperature sensor at the inlet of the heat storage tank detects that the temperature is equal to the temperature of the original temperature working fluid, the thermal electric valve is closed, the passage between the high-pressure original temperature working fluid and the left chamber of the upper pressure chamber is closed, the passage between the left chamber of the upper pressure chamber and the cold working fluid outflow pipeline is opened, and the passage between the right chamber of the upper pressure chamber and the cold working fluid outflow pipeline is controlled to be closed; at the same time, the passage between the left chamber of the lower pressure chamber and the cold working fluid outflow pipeline is controlled to be closed, and the passage between it and the high-pressure original temperature working fluid is connected, and the passage between the right chamber of the lower pressure chamber and the cold working fluid outflow pipeline is controlled to be opened, and the passage between it and the high-pressure original temperature working fluid is closed, and the upper pressure chamber right-inlet working fluid and the lower pressure chamber left-inlet working fluid mode is started.

[0013] Furthermore, multiple anti-phase cold and hot working medium integrated modules are connected in parallel and / or in series to generate more cold and heat, and can obtain hot working medium with higher temperature or cold working medium with lower temperature.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The present invention arranges a hot working medium outlet at the middle position of the pressure chamber, arranges a slider inside the pressure chamber, and fixes elastic thermal materials at both ends of the slider respectively. The original temperature working medium enters the pressure chamber alternately from both ends, and the pressure brought by the high-pressure working medium is used to push the slider to move, thereby driving the stretching and contraction of the elastic thermal material, thereby achieving both heating and cooling by doing work at one time, and taking away the generated heat and cold in time through the working medium and entering the heat storage box and the cold storage box for storage.

DETAILED DESCRIPTION

[0024] The present invention is further explained below in conjunction with the embodiments and drawings, but this is not intended to limit the scope of protection of the present application.

[0025] Example 1 The anti-phase cold and hot working medium integrated system based on the elastic-caloric effect of the present invention comprises at least one group of anti-phase cold and hot working medium integrated modules such as Figure 1 As shown, the anti-phase hot and cold working medium integrated module includes two pressure chambers arranged up and down, namely, an upper pressure chamber 9 and a lower pressure chamber 10. The pressure chambers are in the shape of cylindrical tubes. A hot working medium outlet is arranged in the middle position of each pressure chamber, and working medium flow ports are respectively arranged on both sides. A slider 7 is arranged inside the pressure chamber, and the slider divides the pressure chamber into two cavities that are not interconnected on the left and right. Elastic thermal materials 8 are respectively fixed at both ends of the slider, and the elastic thermal materials on both sides of the slider are stretched or contracted respectively by moving the slider in the pressure chamber; on the one hand, the original temperature working medium box is connected to one end of the first electric three-way valve 1 and the second electric three-way valve 2 through the outlet of the high-pressure pump 5; the other two ends of the first electric three-way valve are respectively connected to a working medium flow port and a cold working medium outflow pipeline of the upper pressure chamber 9; the other two ends of the second electric three-way valve are respectively connected to a working medium flow port and a cold working medium outflow pipeline of the lower pressure chamber 10; On the other hand, the original temperature working medium box is connected to one end of the third electric three-way valve 3 and the fourth electric three-way valve 4 through the outlet of the high-pressure pump 5; the other two ends of the third electric three-way valve are respectively connected to another working medium flow port of the upper pressure cabin 9 and the cold working medium outflow pipeline; the other two ends of the fourth electric three-way valve are respectively connected to another working medium flow port of the lower pressure cabin 10 and the cold working medium outflow pipeline; The cold working medium outflow pipeline is used to connect the cold storage tank 13; the hot working medium outlets are connected to the heat storage tank 12 through the thermal electric valve 11, and a temperature sensor is arranged at the inlet of the heat storage tank; in the initial state, the upper and lower pressure chambers are filled with the working medium at the original temperature, and the slider is located at the non-hot working medium outlet position in the pressure chamber, that is, the two chambers in the pressure chamber have different volumes at the initial stage, and the working medium flows into the pressure chamber from the side with the smaller volume.

[0026] In the initial state, the elastic thermal material of the two cavities of the pressure chamber is stretched on one side and contracted on the other side. Preferably, in the initial state, the slider of the upper pressure chamber is located at 1 / 4 of the length of the upper pressure chamber, and the slider of the lower pressure chamber is located at 3 / 4 of the length of the lower pressure chamber.

[0027] After being pressurized by a high-pressure pump, the original temperature working fluid alternately enters from the working fluid flow ports of the upper pressure chamber and the lower pressure chamber. The pressure brought by the high-pressure working fluid is used to push the slider 7 to move in the corresponding pressure chamber, thereby driving the stretching and contraction of the elastic and thermal materials in the left and right chambers of the slider, so that one work can be done to generate heat and cool. When the slider in the pressure chamber passes the hot working fluid outlet position, the thermal electric valve 11 is triggered, and the hot working fluid outlet is connected to the heat storage tank 12, and the heat generated in one chamber is taken away in time. During this process, the electric three-way valve connected to the other working fluid flow port and the cold storage tank 13 is always turned on, and the cold generated in the other chamber is stored in the cold storage tank. The working fluid flow directions of the upper pressure chamber and the lower pressure chamber are opposite, and the continuous and stable output of cold and heat is achieved through the cooperation of multiple electric three-way valves and the thermal electric valve 11.

[0028] The power of the present invention comes from the pressure of the working fluid. The slider moves in the pressure chamber through the change of the left / right chamber pressure, causing the elastic heat material to absorb / release heat. The specific working process is: The upper and lower pressure chambers are placed horizontally, and working fluid flow ports are respectively set at both ends of the pressure chambers. The original temperature working fluid is pressurized by the high-pressure pump 5 to form high-pressure original temperature working fluid, and then the flow direction of the high-pressure original temperature working fluid is controlled by the coordinated action of the first electric three-way valve, the second electric three-way valve, or the third electric three-way valve and the fourth electric three-way valve. The high-pressure original temperature working fluid enters alternately from both sides of the upper and lower pressure chambers. The original temperature working fluid in one chamber flows out at the hot working fluid outlet after being heated, taking away the heat. The original temperature working fluid in the other chamber is cooled to form a low-temperature working fluid, and the low-temperature working fluid takes away the cold through the cold working fluid outflow pipeline.

[0029] See also Figure 2In the middle (a) figure, the upper pressure cabin has the working fluid entering from the left and the lower pressure cabin has the working fluid entering from the right: the conduction form of the first electric three-way valve 1 and the fourth electric three-way valve 4 is controlled so that the left chamber of the upper pressure cabin is connected to the original temperature working fluid box, and the right chamber of the lower pressure cabin is connected to the original temperature working fluid box; the conduction form of the third electric three-way valve 3 and the second electric three-way valve 2 is controlled so that the right chamber of the upper pressure cabin is connected to the cold working fluid outflow pipeline, and the left chamber of the lower pressure cabin is connected to the cold working fluid outflow pipeline; in the upper pressure cabin, when the high-pressure original temperature working fluid enters from the left working fluid flow port of the upper pressure cabin, the pressure in the left chamber is Under the pushing action, the slider moves to the right, driving the elastic thermostatic material 8 in the left chamber to gradually stretch, and the material changes from austenite to martensite. In this process, the elastic thermostatic material in the left chamber releases heat to the fluid. At the same time, it drives the elastic thermostatic material in the right chamber to gradually shrink, and the material changes from martensite to austenite. The elastic thermostatic material in the right chamber absorbs heat from the fluid; when the slider moves to the hot working fluid outlet, the thermal electric valve opens, and the working fluid in the left chamber flows out from the hot working fluid outlet, taking away heat and relieving pressure. Under the push of the slider, the working fluid in the right chamber flows into the cold working fluid outflow pipeline through the control of the third electric three-way valve, taking away the cold. In the lower pressure chamber, when the high-pressure original temperature working fluid enters from the right working fluid flow port of the lower pressure chamber, the slider moves to the left under the push of the pressure in the right chamber, driving the elastic thermostatic material 8 in the right chamber to gradually stretch, and the material changes from austenite to martensite. During this process, the elastic thermostatic material in the right chamber releases heat to the fluid; at the same time, it drives the elastic thermostatic material in the left chamber to gradually shrink, and the material changes from martensite to austenite, and the elastic thermostatic material in the left chamber absorbs heat from the fluid; when the slider moves to the hot working fluid outlet, the thermal electric valve opens, and the working fluid in the right chamber flows out from the hot working fluid outlet, taking away heat and relieving pressure. Under the push of the slider, the working fluid in the left chamber flows into the cold working fluid outflow pipeline through the control of the second electric three-way valve, taking away the cold.

[0030] In the upper and lower pressure chambers, when the temperature sensor at the inlet of the heat storage tank detects that the temperature is equal to the temperature of the original temperature working medium, the thermal electric valve is closed, the passage between the high-pressure original temperature working medium and the left chamber of the upper pressure chamber is closed, the passage between the left chamber of the upper pressure chamber and the cold working medium outflow pipeline is opened, and the passage between the right chamber of the upper pressure chamber and the cold working medium outflow pipeline is controlled to be closed; at the same time, the passage between the left chamber of the lower pressure chamber and the cold working medium outflow pipeline is controlled to be closed, and the passage between it and the high-pressure original temperature working medium is conducted, and the passage between the right chamber of the lower pressure chamber and the cold working medium outflow pipeline is controlled to be opened, and the passage between it and the high-pressure original temperature working medium is closed, and the upper pressure chamber right-inlet working medium and the lower pressure chamber left-inlet working medium mode is started (see Figure 2 (middle (b)).

[0031] Example 2 like Figure 3As shown, in this embodiment, original temperature working fluid boxes are respectively arranged at the left and right ends of the two pressure chambers, that is, two original temperature working fluid boxes are arranged, and the two original temperature working fluid boxes are respectively responsible for the entry of the respective working fluids at the left and right ends of the pressure chamber. A high-pressure pump 5 is installed at the outlet of each original temperature working fluid box to pressurize the original temperature working fluid to the required pressure. A temperature sensor, a pressure sensor and a flow sensor are equipped at the outlet of the high-pressure pump to monitor the temperature, pressure and flow of the original temperature working fluid in real time to ensure that the system operation parameters are within a reasonable range.

[0032] Temperature sensors are also installed at the inlets of the cold storage box 13 and the heat storage box 12; pressure sensors and flow sensors are set at the inlets of the heat storage box and the cold storage box to monitor the pressure and flow of the inlet working fluid.

[0033] The cold working fluid outflow pipelines are all connected to the cold storage box, and the generated cold energy is stored in the cold storage box, while the hot working fluid generated by the hot working fluid port is led to the heat storage box for storage.

[0034] The present invention can store the heat and cold it generates respectively. In the cooling season, the cold stored in the cold storage box can be used to cool buildings or other cold-using equipment. In the heating season, the heat stored in the heat storage box can be used to heat buildings or other hot-using equipment. The original temperature working fluid after heat exchange returns to the original temperature working fluid box. In the cooling season or the heating season, the excess heat or cold can be converted into the original temperature working fluid after heat exchange with the environment through a spray tower or a heat exchanger, and then sent to the original temperature working fluid box, thereby realizing the recycling of the working fluid.

[0035] Example 3 The system of this embodiment is also provided with a control unit, which is used to control the execution of each component of the system and detect temperature, flow and pressure. The control unit is electrically connected to all the above sensors, and is also electrically connected to all electric three-way valves and electric valves. It can also be electrically connected to the spray tower or heat exchanger.

[0036] Example 4 In order to generate more cold / heat in this embodiment, multiple anti-phase cold / heat working medium integrated modules can be connected in parallel, such as Figure 4 As shown, two modules are connected in parallel, which are respectively recorded as the first module and the second module. The working process is described below: When multiple modules are connected in parallel, the left and right ends share a common original temperature working fluid box and a high-pressure pump.

[0037] The original temperature working fluid coming out of the original temperature working fluid box is pressurized by a high-pressure pump, and two branches are set at the outlet of the high-pressure pump, and the two branches are connected to the first module and the second module respectively. In the first module, the slider moves under the driving action of the high-pressure working fluid, stretching and releasing heat to the elastic and thermal materials in the corresponding cavities of the upper and lower pressure chambers, and the materials change from austenite to martensite, heating the original temperature working fluid, and when the slider reaches the outlet of the hot working fluid, the corresponding thermal electric valve is opened to take away the heat and discharge it into the heat storage tank. At the same time, the elastic and thermal materials in the other cavity of the upper and lower pressure chambers are contracted and cooled, and the materials change from martensite to austenite, cooling the original temperature working fluid, and the cooled cold working fluid is discharged into the cold storage tank. In the second module, the system moves in the same way, and the generated hot working fluid is discharged into the heat storage tank, and the generated cold working fluid is discharged into the cold storage tank. Through the parallel connection of multiple modules, the original temperature working fluid drives the movement of two modules at the same time after being pressurized by a high-pressure pump, and more cold working fluid and hot working fluid can be generated. By following this operation, more modules can be connected in parallel to achieve more cold and hot working fluid output to meet different working quality requirements.

[0038] Example 5 In order to obtain a higher temperature thermal medium in this embodiment, multiple modules can be connected in series, such as Figure 5 The figure is a schematic diagram of the two-module series structure. The following is an explanation of its operation process: In the upper and lower pressure chambers of the first module, the original temperature working fluid from the original temperature working fluid box is pressurized by a high-pressure pump and enters the pressure chamber. Under the driving action of the high-pressure original temperature working fluid, the slider moves, driving the elastic thermostatic material in the cavity to stretch or contract, so that the elastic thermostatic material releases heat to the fluid or absorbs heat. The elastic thermostatic material releases heat to the fluid, heats the original temperature working fluid and turns it into hot working fluid. When the slider reaches the hot working fluid outlet position, the thermal electric valve opens to take away the heat and release the pressure. At the same time, the coldness of the other cavity flows into the cold storage box for storage.

[0039] At this time, the hot working fluid flowing out of the first module serves as the driving working fluid of the second module, and the working fluid flow port flowing into the second module serves as the driving force. Under the action of high pressure, the slider is pushed to move, so that the elastic and thermal material in the cavity of the second module is stretched, and the hot working fluid from the first module is heated. The hot electric valve is opened at the hot working fluid outlet of the second module to obtain a hot working fluid with a higher temperature, which flows into the heat storage tank for storage. In the second module, the elastic and thermal material in another cavity shrinks, and the material changes from martensite to austenite, cooling the hot working fluid from the first module to a temperature close to the original working fluid temperature. Under the push of the slider, it enters the original temperature working fluid box for storage. This cycle is repeated. Through the above operation, the hot working fluid generated by the first module serves as the driving working fluid of the second module, and the elastic and thermal material of the second module stretches and heats the working fluid, and a hot working fluid with a higher temperature is obtained at the hot working fluid outlet of the second module; in addition, the working fluid temperature obtained at the outlet of another cavity of the second module is close to the original working fluid temperature, and enters the original temperature working fluid box for storage, and the cycle continues.

[0040] In this embodiment, the second module can be connected after the two hot working medium outlets of the first module converge, so as to serve as the high-pressure working medium driving force of the second module.

[0041] Example 6 In order to obtain a cold working medium with a lower temperature, multiple modules can be connected in series. Figure 6 As shown, the following takes the process of connecting two modules in series to obtain a lower temperature cold medium as an example: The working process of the first module is the same as that of Example 5. The hot working fluid of the first module is stored in the heat storage tank, and the cold working fluid flowing out of its cold working fluid outflow pipeline is used as the driving working fluid of the second module. The cold working fluid generated by the first module flows into the second module as its driving working fluid, and is further collected in the cold storage tank through the cold working fluid outflow pipeline of the second module to obtain a cold working fluid with a lower temperature. At the same time, the working fluid temperature obtained at the hot working fluid outlet of the second module is close to the original working fluid temperature, and enters the original temperature working fluid tank for storage and continues to circulate.

[0042] Any matters not described in the present invention are applicable to the prior art.
