Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of shutter, in particular to a phase change temperature control shutter. BACKGROUND

[0002] With the improvement of people's living standards, people's requirements for the comfort of indoor environment are also higher and higher, and the building energy consumption, such as air conditioning refrigeration and heating energy consumption, is also increased, which causes the problem of rapid energy consumption and environmental pollution. In the past few years, building energy saving is mainly realized by improving the utilization rate of air conditioning, heating and other equipment, but now the energy utilization rate of equipment has reached a bottleneck. The air cooling effect of air conditioning and other refrigeration equipment brings joint discomfort to the elderly, which is one of the pain points of the elderly population that needs to be solved.

[0003] At present, the application of shutter in building to some extent adopts materials with good heat insulation, effectively maintains the indoor temperature, and achieves the purpose of saving energy. Only by adjusting the angle of the blade to control the amount of light entering, the sound and heat insulation effect can be achieved. However, most of the shutters on the market only block the light or heat through the physical barrier of the blade, and the heat storage and temperature adjustment effect is poor, which needs to be further improved.

[0004] The existing patent with authorization announcement No. CN110242196B discloses a shutter for adjusting temperature and a preparation method thereof, the shutter comprises a plurality of fixedly connected blades, wherein the blades are filled with a composite shaped phase change material made of organic phase change material and inorganic supporting material. The method comprises the process of filling the composite shaped phase change material made of organic phase change material and inorganic supporting material into the blades. The composite phase change energy storage material provided by the technology has simple preparation process, convenient operation, low requirement for operators, and can save labor cost and raw material cost. However, the capacity of the composite shaped phase change material to absorb external heat for heat storage is limited, and when the weather is continuously high in summer, the composite shaped phase change material is easy to be saturated in heat storage, and then cannot continuously regulate the temperature of indoor environment, which has certain limitations. SUMMARY

[0005] The purpose of the present application is to provide a phase change temperature control shutter, which can adjust the environmental temperature through the heat absorption and heat dissipation of the composite phase change material, and when the composite phase change material is saturated in heat storage due to continuous high temperature, the refrigeration module can be used for cooling, so as to facilitate the shutter to continuously regulate the temperature of indoor environment and maintain the relative constancy of indoor environmental temperature.

[0006] The embodiment of the present application is realized as follows:

[0007] The embodiment of the present application provides a phase change temperature control louver, which comprises a mounting frame and a plurality of louver blades arranged on the mounting frame, the louver blades are hollow, and each of the louver blades is internally provided with an evaporator; the evaporator penetrates the louver blade, and a composite phase change material is filled between the outer wall of the evaporator and the inner wall of the louver blade; and the louver further comprises a refrigeration module, which is in communication with the evaporator.

[0008] Further, in some embodiments of the present application, the refrigeration module comprises a compressor, an expansion valve and a condenser, the compressor is in communication with the expansion valve, the expansion valve is in communication with the evaporator, the evaporator is in communication with the condenser, and the condenser is in communication with the compressor.

[0012] Further, in some embodiments of the present application, the louver blade is internally provided with a connecting piece, and the connecting piece connects the evaporator and the louver blade.

[0013] Further, in some embodiments of the present application, the mounting frame is provided with a glass plate, and the louver blade is arranged on one side of the glass plate.

[0014] Further, in some embodiments of the present application, the cross section of the louver blade along the radial direction thereof is oval.

[0015] Further, in some embodiments of the present application, the composite phase change material adopts one or more of expanded graphite encapsulated paraffin, stearic acid-decanoic acid binary low eutectic phase change material, magnesium chloride hexahydrate and calcium chloride hexahydrate low eutectic phase change material.

[0016] Further, in some embodiments of the present application, the louver blade is made of aluminum or copper.

[0017] Compared with the prior art, the embodiment of the present application has at least the following advantages or beneficial effects:

[0018] The phase change temperature control shutter provided by the embodiment of the present application comprises a mounting frame and a plurality of shutter blades arranged on the mounting frame, the shutter blades are hollow, and each of the shutter blades is internally provided with an evaporator; the evaporator penetrates through the shutter blade, and a composite phase change material is filled between the outer wall of the evaporator and the inner wall of the shutter blade; and the phase change temperature control shutter further comprises a refrigeration module, which is in communication with the evaporator.

[0019] In actual use, the phase change temperature control shutter can be installed on a window, and the shutter blades are located on the indoor side, and a temperature sensor is used to measure the indoor temperature and send a temperature signal to a signal processing system. When the ambient temperature in the room is greater than the phase change temperature of the composite phase change material, the composite phase change material can absorb heat in the surrounding environment and convert it into its own latent heat, and when the ambient temperature is less than the phase change temperature of the composite phase change material, it can release its own latent heat to the surrounding environment, so that it can adjust the ambient temperature through the heat absorption and heat dissipation of the composite phase change material.

[0020] When the continuous high temperature causes the composite phase change material to be saturated in heat storage, the composite phase change material cannot continue to absorb heat in the surrounding environment, and when the indoor temperature gradually increases and is higher than the maximum temperature set by the signal processing system, the signal processing system controls the heat dissipation fan and the compressor to start working, the refrigerant is pressurized to a high pressure state and flows through the expansion valve, and then the refrigerant undergoes liquid-gas phase change through the evaporator to absorb a large amount of heat, so that the shutter blades are rapidly cooled, the composite phase change material in the shutter blades starts to store cold at the same time and absorbs heat in the room to reduce the indoor temperature, the liquid(gas) body flowing through the evaporator flows into the condenser, the refrigerant undergoes gas-liquid phase change, and the excess heat is taken away by the heat dissipation fan, and finally the refrigerant flows into the compressor for circulation.

[0021] However, when the ambient temperature decreases to the minimum temperature set by the signal processing system, the signal processing system controls the heat dissipation fan and the compressor to stop working. In this way, the temperature can be lowered by the refrigeration module, which facilitates the continuous regulation of the indoor temperature by the shutter and maintains the relative constancy of the indoor ambient temperature.

[0022] The phase change temperature control shutter provided by the present application not only reduces the consumption of energy and improves the comfort of the indoor environment, but also enhances the heat storage and temperature regulation effect of ordinary shutters, increases the application range of the shutter under different regions, different climates and different temperature conditions, and better solves the air cooling effect problem of air conditioning and other refrigeration equipment. In the case of the increasingly serious aging problem in China at present, the product has good application prospect. BRIEF DESCRIPTION OF DRAWINGS

[0040] The embodiment provides a phase change temperature control louver, which comprises a mounting frame 1 and a plurality of louver blades 2 arranged on the mounting frame 1, the louver blades 2 are hollow, and each of the louver blades 2 is internally provided with an evaporator 3; the evaporator 3 penetrates through the louver blade 2, and a composite phase change material 4 is filled between the outer wall of the evaporator 3 and the inner wall of the louver blade 2; and the phase change temperature control louver further comprises a refrigeration module, and the refrigeration module is communicated with the evaporator 3.

[0041] The refrigeration module comprises a compressor, an expansion valve and a condenser, the compressor is communicated with the expansion valve, the expansion valve is communicated with the evaporator 3, the evaporator 3 is communicated with the condenser, and the condenser is communicated with the compressor; the phase change temperature control louver further comprises a signal processing system and a temperature sensor, and the temperature sensor and the compressor are both in communication connection with the signal processing system; and the condenser is provided with a cooling fan, and the cooling fan is in communication connection with the signal processing system.

[0042] In actual use, the phase change temperature control louver can be installed on a window, the louver blades 2 are located on one side of the indoor side, and the temperature sensor is used for measuring the indoor temperature and sending a temperature signal to the signal processing system.

[0043] When the ambient temperature in the room is greater than the phase change temperature of the composite phase change material 4, the composite phase change material 4 can absorb the heat in the surrounding environment and convert it into its own latent heat, and when the ambient temperature is less than the phase change temperature of the composite phase change material 4, the composite phase change material 4 can release its own latent heat to the surrounding environment, so that the composite phase change material 4 can adjust the ambient temperature through heat absorption and heat dissipation.

[0044] When the composite phase change material 4 is saturated due to continuous high temperature, the composite phase change material 4 cannot continue to absorb the heat in the surrounding environment, when the indoor temperature gradually increases and is higher than the highest temperature set by the signal processing system, the signal processing system controls the cooling fan and the compressor to start working, the refrigerant is pressurized to a high pressure state and flows through the expansion valve, then the refrigerant undergoes liquid-gas phase change through the evaporator 3, absorbs a large amount of heat, so that the louver blades 2 rapidly cool down, the composite phase change material 4 in the louver blades 2 simultaneously starts to store cold and absorbs the heat in the room, reduces the indoor temperature, the liquid (gas) flowing through the evaporator 3 flows into the condenser, the refrigerant undergoes gas-liquid phase change, and the excess heat is taken away by the cooling fan, and finally the refrigerant flows into the compressor to circulate.

[0045] But when the ambient temperature drops to the lowest temperature set by the signal processing system, the signal processing system controls the cooling fan and the compressor to stop working. In this way, the refrigeration module can be used for cooling, and the louver can continuously regulate the indoor temperature, so that the indoor ambient temperature is relatively constant.

[0046] The phase change temperature control louver provided by the application not only reduces energy consumption, improves the comfort of the indoor environment, but also enhances the heat storage temperature adjustment effect of the ordinary louver, increases the application range of the louver under different regions, different climates and different temperature conditions, and better solves the air cooling effect problem of the air conditioning and other refrigeration equipment. Under the condition that the aging problem in China is becoming more and more serious, the product has good application prospect.

[0047] Optionally, the signal processing system of the embodiment can adopt an AT89S51 chip.

It is not limited to the AT89S51 chip in the embodiment. The temperature sensor of the embodiment can adopt a K-type thermocouple or a thermal infrared sensor.

[0048] Optionally, in the plurality of evaporators 3 of the embodiment, each evaporator 3 can be individually connected to the condenser and the expansion valve, respectively.

[0049] As shown in Figures 1-6 In some embodiments of the application, the above also includes a wireless receiving module, and the wireless receiving module is in communication connection with the signal processing system.

[0050] The application sets the wireless receiving module, which is in communication connection with the signal processing system, so that the user can remotely send a signal to the signal processing system through wireless transmission, thereby facilitating remote wireless control of the working of the phase change temperature control louver provided by the application. Optionally, the wireless receiving module of the embodiment can adopt a 5G module, a WiFi module, etc.

[0051] As shown in Figures 1-6 In some embodiments of the application, the louver blade 2 is provided with a connecting piece 5, and the connecting piece 5 connects the evaporator 3 and the louver blade 2, respectively.

[0052] As shown in Figures 1-6 In some embodiments of the application, the mounting frame 1 is provided with a glass plate 6, and the louver blade 2 is arranged on one side of the glass plate 6.

[0053] As shown in Figures 1-6 In some embodiments of the application, the cross section of the louver blade 2 along its radial direction is oval.

[0054] like Figures 1-6 As shown, in some embodiments of the present invention, the above-mentioned composite phase change material 4 is one or more of the following: expanded graphite encapsulated paraffin (phase change temperature is 16-40℃), stearic acid-decanoic acid binary eutectic phase change material, and magnesium chloride hexahydrate and calcium chloride hexahydrate eutectic phase change material.

[0055] During manufacturing, the prepared composite phase change material 4 is filled into the hollow structure of the louver blade 2 and then encapsulated to obtain the phase change temperature-controlled louver of this embodiment of the invention. The encapsulation material can be porous materials such as expanded perlite, activated carbon, or diatomaceous earth, or microencapsulation technology can be used. The proportion of the encapsulation material is approximately 5%-30%.

[0056] like Figures 1-6 As shown, in some embodiments of the present invention, the louver blades 2 are made of aluminum or copper. Aluminum or copper have good thermal conductivity, which facilitates heat transfer.

[0057] In summary, embodiments of the present invention provide a phase change temperature-controlled louver, including a mounting frame 1 and a plurality of louver blades 2 disposed on the mounting frame 1. The interior of each louver blade 2 is hollow, and an evaporator 3 is disposed inside each louver blade 2. The evaporator 3 penetrates through the louver blade 2, and a composite phase change material 4 is filled between the outer wall of the evaporator 3 and the inner wall of the louver blade 2. The evaporator 3 also includes a refrigeration module, which is connected to the evaporator 3.

[0058] The aforementioned refrigeration module includes a compressor, an expansion valve, and a condenser. The compressor is connected to the expansion valve, the expansion valve is connected to the evaporator 3, the evaporator 3 is connected to the condenser, and the condenser is connected to the compressor. The module also includes a signal processing system and a temperature sensor. The temperature sensor and the compressor are both communicatively connected to the signal processing system. The condenser is equipped with a cooling fan, which is communicatively connected to the signal processing system.

[0059] In practical use, the phase change temperature-controlled louver can be installed on a window, with the louver blades 2 located on the indoor side. A temperature sensor measures the indoor temperature and sends the temperature signal to the signal processing system. When the indoor ambient temperature is higher than the phase change temperature of the composite phase change material 4, the composite phase change material 4 absorbs heat from the surrounding environment and converts it into its own latent heat. When the ambient temperature is lower than the phase change temperature of the composite phase change material 4, it releases its own latent heat to the surrounding environment. In this way, it can regulate the ambient temperature through the heat absorption and dissipation of the composite phase change material 4.

[0060] When the temperature is continuously high so that the composite phase change material 4 is saturated in heat storage, the composite phase change material 4 cannot continue to absorb heat in the surrounding environment, when the indoor temperature gradually becomes higher than the maximum temperature set by the signal processing system, the signal processing system controls the cooling fan and the compressor to start working, the refrigerant is pressurized to a high pressure state and flows through the expansion valve, and then the refrigerant undergoes liquid-gas phase change through the evaporator 3, absorbs a large amount of heat, so that the louver blade 2 rapidly cools down, the composite phase change material 4 in the louver blade 2 starts to store cold at the same time, and absorbs the heat in the room, reduces the indoor temperature, and the liquid(gas) flowing through the evaporator 3 flows into the condenser, the refrigerant undergoes gas-liquid phase change, and the excess heat is taken away by the cooling fan, and finally the refrigerant flows into the compressor for circulation.

[0061] But when the ambient temperature drops to the minimum temperature set by the signal processing system, the signal processing system controls the cooling fan and the compressor to stop working. In this way, the cooling can be realized by the refrigeration module, and the louver can continuously regulate the temperature in the room, so as to maintain the relative constancy of the indoor environment temperature. The phase change temperature control louver provided by the application not only reduces the energy consumption and improves the comfort of the indoor environment, but also enhances the heat storage and temperature regulation effect of the ordinary louver, increases the application range of the louver in different regions, different climates and different temperature conditions, and better solves the air cooling effect problem of the air conditioner and other refrigeration equipment. In the case of the increasingly serious aging problem in China at present, the product has good application prospect.

It is obvious for those skilled in the art that the application is not limited to the details of the above exemplary embodiments, and the application can be implemented in other specific forms without departing from the spirit or essential characteristics of the application.
