Description

Technical Field

[0001] The present invention relates to the field of building energy-saving and environmental protection equipment, and in particular to a self-sustaining heat-activated energy-saving wall with active thermal insulation and instantaneous heat and moisture load regulation functions and an operation control method thereof. Background Art

[0002] At present, building air conditioning energy consumption accounts for about 20% of the world's total energy consumption, and the indoor thermal and humid environment control of public buildings and civil buildings relies heavily on large central air conditioning systems or small air conditioners. In order to reduce building energy consumption, especially air conditioning energy consumption, various forms of building insulation materials have been widely used in building envelopes for decades to improve the thermal insulation performance of buildings. However, insulation materials with high embodied energy consumption and embodied carbon emissions are not a panacea for solving building energy consumption problems. The embodied carbon emissions and embodied energy consumption contained in these insulation materials have been confirmed by researchers to be comparable to the operating energy consumption and operating carbon emissions generated during the long-term use of buildings. The current dilemma of over-reliance on air conditioning systems to regulate the indoor environment and reliance on insulation materials to improve the thermal performance of buildings in the construction field has received widespread attention from stakeholders, and the demand for research and development of new low-carbon building environment solutions is also increasing day by day.

[0003] The heat-activated building energy system is an efficient and compact building energy-saving and energy supply system. However, the system is subject to many limitations of existing technologies and there are still some problems that need to be solved urgently to accelerate the popularization of its engineering application. On the one hand, the traditional heat-activated building energy system needs to be equipped with an independent low-grade heat source / cold source acquisition subsystem to provide it with a stable low-grade heat / cold supply during use. For the traditional heat-activated building energy system, common forms of separated low-grade heat source / cold source acquisition subsystems include: (1) shallow geothermal systems buried under the surface soil; (2) solar thermal collection systems or space radiation cooling systems installed on the roof / facade / ground; and (3) air source heat pump systems installed around the building. However, no matter which separated low-grade heat source / cold source acquisition subsystem is used in the traditional heat-activated building system, there are problems such as the complexity of the entire heat-activated building energy system, the large number of external pipelines and ancillary equipment, and the difficulty of system operation and maintenance in actual projects. In particular, due to the control of urban and rural landscape, aesthetic restrictions on building facades, protection of groundwater resources and mineral resources, etc., a large number of buildings generally have the problem of installing solar collectors and air source heat pumps on buildings or drilling wells (installing shallow geothermal systems) in the process of installing traditional thermally activated building energy systems. The difficulty in obtaining low-grade energy for thermally activated building energy systems has become the primary bottleneck problem restricting the large-scale engineering application of this technology. Therefore, whether it is possible to develop an integrated low-grade heat source / cold source acquisition subsystem with highly integrated characteristics, high low-grade heat acquisition efficiency, convenient installation / maintenance / repair, and low impact on urban and rural landscape or architectural aesthetics is crucial to the promotion of thermally activated energy-saving walls. On the other hand, during operation, traditional thermally activated energy-saving walls mainly rely on the embedded pipe heat injection system embedded in a specific structural layer of the wall to inject low-grade heat / cold into the wall to form an invisible thermal barrier, thereby isolating the adverse interference of the outdoor thermal environment on the indoor thermal environment. However, traditional heat-activated walls are subject to limitations such as the embedded pipe layer structural design and constituent materials. The injected low-grade heat will accumulate around the embedded pipes in large quantities and produce a serious excessive heat accumulation effect. Although some of the disclosed enhanced heat injection design and operation control methods can alleviate the excessive heat accumulation phenomenon generated during the heat injection process to a certain extent and achieve the purpose of improving the thermal performance of such walls, the problem that the heat-activated building energy system cannot quickly respond to the instantaneous indoor heat load and cannot handle the room moisture load has never received attention and resolution. This also directly leads to the current buildings that use traditional heat-activated building energy systems still need to be equipped with separate traditional air-conditioning systems to cope with the instantaneous heat load and room moisture load of the room.In short, although traditional heat-activated energy-saving walls can effectively reduce the heat load of the enclosing structure, they still need to be equipped with traditional air-conditioning systems to deal with the technical shortcomings of the instantaneous heat load and humidity load of the room. As a result, this technology has many unfavorable problems in actual application, such as high comprehensive investment and operating costs, large workload of operation and maintenance, and significantly increased system complexity. Summary of the invention

[0004] The purpose of the present invention is to provide a self-sustaining heat-activated energy-saving wall and its operation control method in view of the deficiencies in the prior art. The new wall system has the functions of active thermal insulation of the outer protective structure and instantaneous processing of room heat / humidity loads. Its low-grade heat source / cold source acquisition subsystem is integrated into the wall, overcoming the technical disadvantages of traditional heat-activated energy-saving walls that heavily rely on independent low-grade heat source / cold source acquisition subsystems separated from the wall to provide heat / cold supply. In addition, it can effectively utilize the invisible thermal barrier formed in the heat-activated wall to actively reduce the heat loss of the room, and at the same time, it has the unique function of efficiently and quickly processing the instantaneous indoor heat load and room moisture load, which significantly improves the feasibility and technical economy of the heat-activated energy-saving wall system in engineering applications.

[0005] The technical solution adopted to achieve the purpose of the present invention is:

[0006] It includes a wall frame and an outer wall panel layer, an insulation panel layer, an intermediate wall panel layer, a temperature control panel layer, an inner wall panel layer and a heat-activated energy system which are sequentially installed in the wall frame from the outside; an outer air interlayer is provided between the outer wall panel layer and the insulation panel layer, and a cavity filled with a temperature-control material is provided inside the temperature control panel layer; the heat-activated energy system includes a steam compression mechanism, a working fluid reversing mechanism, a working fluid throttling mechanism, a cold / heat extraction heat exchanger, a cold / heat injection heat exchanger and a circulating working fluid, the cold / heat extraction heat exchanger is installed in the outer air interlayer, the outer air interlayer is mainly used for installing a fixed cold / heat extraction heat exchanger, and is used to provide spatial conditions for the cold / heat extraction heat exchanger to exchange heat with the surrounding air during operation, and the cold / heat extraction heat exchanger located in the outer air interlayer can continuously and stably provide a low-grade cold and heat source for the cold / heat injection heat exchanger through the upwind and downwind ports arranged on the outer wall panel. The cold / heat injection heat exchanger is installed in the temperature control material filled cavity, the cold / heat extraction heat exchanger and the cold / heat injection heat exchanger are filled with the circulating working fluid, the steam compression mechanism is connected to one end of the cold / heat extraction heat exchanger and the cold / heat injection heat exchanger respectively through the working fluid reversing mechanism, and the other end of the cold / heat extraction heat exchanger and the cold / heat injection heat exchanger are connected together through the working fluid throttling mechanism. In the present invention, the working fluid reversing mechanism (usually called a four-way reversing valve) is mainly used to switch the working fluid flow direction of the heat-activated building energy system in winter and summer to realize the summer operation mode and the winter operation mode; the throttling mechanism is mainly used to throttle and reduce the pressure of the condensed working fluid, which is mainly a capillary tube, an electronic expansion valve or a thermal expansion valve.

[0007] Preferably, a condensate drainage system is provided at the bottom of the wall frame corresponding to the cold / heat extraction heat exchanger and the cold / heat injection heat exchanger. During the operation of the heat-activated building energy system, the cold / heat extraction heat exchanger in the "winter thermal insulation mode" and the "winter heating mode", and the cold / heat injection heat exchanger in the "summer thermal insulation mode" and the "summer cooling and dehumidification mode" will produce condensation when the wall temperature is lower than the air dew point temperature. If the condensed water is not discharged from the wall in time, the condensed water will penetrate into the wall and affect the use of the wall. Therefore, it is necessary to set a drainage groove at the bottom of the outer air interlayer and the inner air interlayer, that is, at the upper surface of the bottom of the wall frame, and discharge it to the drainage riser through the drainage series pipe, and finally discharge it from the wall to prevent the condensed water from accumulating in the wall and causing problems such as seepage and leakage.

[0008] Preferably, the condensate drainage system includes an outer air interlayer drainage groove, an inner air interlayer drainage groove, a condensate drainage riser, a first condensate drainage series pipe and a second condensate drainage series pipe; the outer air interlayer drainage groove is located at the bottom of the wall frame below the cold / heat extraction heat exchanger, the inner air interlayer drainage groove is located at the bottom of the wall frame below the cold / heat injection heat exchanger, the condensate drainage riser is arranged in the side of the wall frame, and the outer air interlayer drainage groove and the inner air interlayer drainage groove are respectively connected to the condensate drainage riser through the first condensate drainage series pipe and the second condensate drainage series pipe.

[0009] Preferably, the outer wall panel layer is provided with an outer wall panel upper air outlet and an outer wall panel lower air outlet near the top and bottom, respectively, and an outer wall panel upper air outlet and an outer wall panel lower air outlet are respectively installed near the outer side of the outer wall panel upper air outlet and the outer wall panel lower air outlet, and an outer wall panel upper air outlet dust filter and an outer wall panel lower air outlet dust filter are respectively installed near the outer air interlayer side of the outer wall panel upper air outlet and the outer wall panel lower air outlet. During the operation of the heat-activated building energy system, the air outlets on the outer wall panels and the inner wall panels are mainly used for energy exchange with the outdoor environment and the indoor environment. For example, the air outlets on the outer wall panels and the outer wall panel lower air outlet are mainly used to continuously provide a low-grade energy source for the cold / heat extraction heat exchanger during operation. If there is no outer wall panel air outlet and the outer wall panel lower air outlet together with the outer air interlayer to form an open energy acquisition space, the cold / heat extraction heat exchanger can only extract heat from the "closed outer air interlayer" where the outer wall panel air outlet is not set. However, the volume of the closed outer air layer is limited, and the heat it can provide cannot sustain the long-term needs of the entire system. Therefore, it is necessary to set up upper and lower air vents on the outer wall panels and connect them to the outer air layer, so that the wall can provide a stable and continuous low-grade heat source for the heat-activated building energy system in the winter operation mode. Similarly, it can also provide a stable and continuous low-grade cold source for the heat-activated building energy system in the summer mode.

[0010] Preferably, the inner wall panel layer is provided with an inner wall panel upper air outlet and an inner wall panel lower air outlet near the top and bottom, respectively, and an inner wall panel upper air outlet and an inner wall panel lower air outlet are respectively installed near the outside of the inner wall panel upper air outlet and the inner wall panel lower air outlet, and an inner wall panel upper air outlet dust filter and an inner wall panel lower air outlet dust filter are respectively installed near the inner air interlayer on the inner wall panel upper air outlet and the inner wall panel lower air outlet. The inner wall panel upper air outlet and the inner wall panel lower air outlet are mainly used as indoor air to enter the wall for heat and mass exchange in the summer cooling and dehumidification mode. In the summer cooling and dehumidification mode, the indoor air that needs to be cooled and dehumidified can enter the inner air interlayer through the upper air outlet and the lower air outlet opened on the inner wall panel, and contact the wall surface of the temperature control panel layer here to achieve the cooling and dehumidification effect. If the upper air outlet and the lower air outlet are not opened on the inner wall panel, the indoor air will not be able to enter the inner air interlayer and complete the cooling and dehumidification process.

[0011] Preferably, the temperature control material filling cavity is filled with phase change energy storage material.

[0012] Preferably, an inner air interlayer is provided between the temperature control plate layer and the inner wall plate layer. The inner air interlayer is mainly used to provide a space condition for the inner wall surface of the temperature control plate layer to exchange heat and mass with the air in the summer cooling and dehumidification mode. By providing an air flow channel between the temperature control plate layer and the inner wall plate and connecting with the upper air outlet and the lower air outlet on the inner wall plate, the inner air interlayer has the conditions for the indoor ambient air to enter the inner air interlayer and be cooled by the inner wall surface of the temperature control plate layer. Preferably, an equipment cavity is provided on the inner side of the wall frame, and the steam compression mechanism, the working fluid reversing mechanism and the working fluid throttling mechanism are installed in the equipment cavity; the condensate drainage riser completely penetrates the wall frame from top to bottom and passes through the equipment cavity. The steam compression mechanism, the working fluid reversing mechanism and the working fluid throttling mechanism can be installed in the equipment cavity, so that the overall structure of the wall is more compact, and the condensate drainage riser can discharge the condensate out of the wall frame.

[0013] Preferably, the insulation board layer, the middle wall board layer and the temperature control board layer are connected by a close fitting connection, or an air gap is provided between two adjacent structural layers. A close connection can reduce the overall thickness of the wallboard, while providing an air gap can further improve the thermal performance of the wall, but the thickness of the wallboard will increase.

[0014] Preferably, the exterior wall panel layer is made of controllable color-changing glass, and can also be made of semi-transparent materials such as concrete panels, photovoltaic panels or solar panels. In the winter operation mode, the exterior wall panel layer is in a non-colored state, at which time the outdoor solar radiation can penetrate the exterior wall panel layer and heat the outer air interlayer, thereby improving the efficiency of the cold / heat extraction, heat exchange and heat removal installed on the inner side of the exterior wall panel layer; in the summer operation mode, the exterior wall panel layer is in a colored state, at which time most of the solar radiation will be absorbed and isolated by the exterior wall panel layer and cannot enter the outer air interlayer, thereby improving the efficiency of the cold / heat extraction, heat exchange and heat removal installed on the inner side of the exterior wall panel layer.

[0015] Preferably, the inner wall panel layer is made of concrete panels, and may also be made of glass panels or metal panels.

[0016] The present invention also discloses an operation control method of a self-sustaining heat-activated energy-saving wall, comprising the self-sustaining heat-activated energy-saving wall, the method comprising four operation control methods: a summer heat preservation and insulation mode, a summer cooling and dehumidification mode, a winter heat preservation and insulation mode, and a winter heating mode;

[0017] (1) When the room is in a thermally stable state for a long time in summer and there is no need to deal with the room's wet load, the summer thermal insulation mode is adopted: first, the air vent opening and closing plate on the outer wall plate and the air vent opening and closing plate under the outer wall plate are opened, and the air vent opening and closing plate on the inner wall plate and the air vent opening and closing plate under the inner wall plate are closed. The steam compression mechanism is started and the circulating working medium reversing mechanism is controlled so that the A end is connected to the D end and the B end is connected to the C end. At this time, the steam compression mechanism absorbs air from the cold / heat injection heat exchanger to evaporate and extracts heat from the phase change energy storage material in the temperature control plate layer to reduce the temperature of this layer. The gaseous working medium enters the steam compression mechanism through the steam compression mechanism inlet and is compressed to increase the temperature. The heated gas The gas-liquid two-phase working medium enters the cooling / heat extraction heat exchanger through the outlet of the vapor compression mechanism to dissipate heat, condense and liquefy. The liquefied liquid working medium flows through the H end and G end of the working medium throttling mechanism in turn and produces a throttling and pressure reduction effect. The gas-liquid two-phase working medium after throttling and pressure reduction enters the cooling / heat injection heat exchanger again to absorb air and evaporate, and extract heat from the phase change energy storage material in the temperature control plate layer and reduce the temperature of this layer. This cycle continues until the temperature in the temperature control plate layer drops to the set value. In this mode, the air enclosed in the inner air interlayer has the potential to condense and liquefy after cooling, and the condensed water will be collected through the inner air interlayer drainage groove and discharged to the condensed water drainage riser through the condensed water drainage series pipe.

[0018] (2) When the room temperature fluctuates instantaneously in summer, generating instantaneous cold load and instantaneous wet load, or when the room only needs to deal with the wet load inside the room, the summer cooling and dehumidification mode is adopted: in this mode, the operation control of the heat-activated energy system and the opening strategy of the air vent openable and closable air plate on the outer wall panel and the air outlet openable and closable air plate on the outer wall panel are completely consistent with the summer thermal insulation mode. The difference is that the air vent openable and closable air plate on the inner wall panel and the air vent openable and closable air plate under the inner wall panel are both in the open state; in this mode, the air that continuously circulates in the inner air interlayer will condense and liquefy after dehumidification and cooling, and the condensed water will also be collected through the inner air interlayer drainage groove and discharged to the condensed water drainage riser through the condensed water drainage series pipe.

[0019] (3) When the room is in a thermally stable state for a long time in winter, the winter thermal insulation mode is adopted: first, the air plate on the outer wall panel and the air plate under the outer wall panel are opened, and the air plate on the inner wall panel and the air plate under the inner wall panel are closed. The steam compression mechanism is started and the circulating medium reversing mechanism is controlled to connect the A end with the C end and the B end with the D end. At this time, the compressor absorbs air from the cold / heat extraction heat exchanger for evaporation and extracts the low-grade heat contained in the outdoor air from the outer air interlayer. The gaseous medium enters the steam compression mechanism through the steam compression mechanism inlet and is compressed to increase the temperature. The heated gaseous medium enters the cold / heat extraction heat exchanger through the steam compression mechanism outlet. The amount / heat is injected into the heat exchanger to dissipate heat and melt the phase change energy storage material in the temperature control plate layer. After the heat is dissipated, the gaseous working medium condenses and liquefies and flows through the G end and H end of the working medium throttling mechanism in turn to produce a throttling and pressure reduction effect. After throttling and pressure reduction, the gas-liquid two-phase working medium enters the cold / heat extraction heat exchanger again to absorb air and evaporate and extract the low-grade heat contained in the outdoor air from the outer air interlayer. This cycle continues until the temperature in the temperature control plate layer rises to the set value. In this mode, the air that is continuously circulating in the outer air interlayer has the potential to condense and liquefy after dehumidification and cooling. The condensed water will be collected through the drainage groove of the outer air interlayer and discharged to the condensed water drainage riser through the condensed water drainage series pipe;

[0020] When the room temperature fluctuates instantaneously in winter and generates instantaneous heat load, the winter heating mode is adopted: in this mode, the operation control of the heat-activated energy system and the opening strategy of the openable and closable air plates on the outer wall panels and the openable and closable air plates under the outer wall panels are exactly the same as the summer thermal insulation mode. The difference is that the openable and closable air plates on the inner wall panels and the openable and closable air plates under the inner wall panels are both in the open state; in this mode, the condensation water discharge strategy in the outer air layer is consistent with the winter thermal insulation mode.

[0021] Compared with the prior art, the present invention has the following beneficial effects: (1) The self-sustaining heat-activated energy-saving wall and its operation control method of the present invention solve the technical drawbacks of the traditional heat-activated building energy system that over-relies on an external independent low-grade heat source / cold source acquisition subsystem to provide long-term heat / cold supply. The self-heat activation process can be achieved through a low-grade heat source / cold source acquisition system integrated into the wall, so that this type of technology can be promoted and applied to projects that were previously restricted by urban / rural landscape control, building facade aesthetics restrictions, and site well drilling restrictions and could not use heat-activated building energy systems; (2) The self-sustaining heat-activated energy-saving wall and its operation control method of the present invention have room instantaneous energy saving that the previous heat-activated energy-saving wall did not have The self-sustaining heat-activated energy-saving wall and its operation control method have a high degree of productization and componentization. Compared with the traditional heat-activated building energy system, the self-sustaining heat-activated energy-saving wall and its operation control method have greatly simplified the steps of construction, installation, operation and maintenance, inspection and disassembly, and can be installed and disassembled like components, which is suitable for the development of prefabricated buildings advocated by the country and has high application and promotion value.

[0039] like Fig. 9As shown, the heat activated energy system 9 is composed of a steam compression mechanism 9-1, a working medium reversing mechanism 9-2, a working medium throttling mechanism 9-3 arranged in the equipment cavity 1-5, a cold / heat extraction heat exchanger 9-4 arranged inside the outer air interlayer 3, a cold / heat injection heat exchanger 9-5 arranged in the temperature control material filled cavity 6-1 in the temperature control plate layer 6, and a circulating working medium 9-6. The working medium reversing mechanism (usually called a four-way reversing valve) in the present invention is mainly used to switch the working medium flow direction of the heat activated building energy system in winter and summer to realize the summer operation mode and the winter operation mode; the throttling mechanism is mainly used to throttle and reduce the pressure of the condensed working medium, which is mainly a capillary tube, an electronic expansion valve or a thermal expansion valve.

[0040] like Figure 10-13 As shown, the bottom of the steam compression mechanism 9-1 is fixedly connected to the equipment cavity 1-5 through a fixing mechanism 9-7 with a shock-absorbing pad, and the upper part thereof is provided with a steam compression mechanism inlet 9-8 and a steam compression mechanism outlet 9-9, which are respectively connected to the A end and the B end of the working medium reversing mechanism 9-2.

[0041] In the present invention, the preferred connection mode between the insulation board layer 4, the intermediate wall board layer 5 and the temperature control board layer 6 is a close fitting connection, and an air gap can also be set between two adjacent structural layers. The temperature control material filling cavity 6-1 is preferably filled with a phase change energy storage material 6-2, and the phase change temperature is preferably set to 18-24°C. It can also be filled with liquid (such as water or heat transfer oil) or solid (such as metal powder or recycled building materials).

[0042] The present invention also discloses an operation control method of a self-sustaining heat-activated energy-saving wall, which has four operation control methods: "summer thermal insulation mode", "summer cooling and dehumidification mode", "winter thermal insulation mode" and "winter heating mode".

[0043] (1) When the room is in a thermally stable state for a long time in summer and there is no need to deal with the room's wet load, the summer thermal insulation mode is adopted: first, the air vent opening and closing plate 2-3 on the outer wall plate and the air vent opening and closing plate 2-4 on the lower wall plate are opened, and the air vent opening and closing plate 8-3 on the inner wall plate and the air vent opening and closing plate 8-4 on the lower wall plate are closed, and the steam compression mechanism 9-1 is started and the circulating working medium reversing mechanism 9-2 is controlled so that the A end is connected to the D end and the B end is connected to the C end. At this time, the steam compression mechanism 9-1 absorbs evaporation from the cold / heat injection heat exchanger 9-5 and extracts heat from the phase change energy storage material 6-2 in the temperature control plate layer 6 and reduces The temperature of this layer, the gaseous working medium enters the steam compression mechanism 9-1 through the steam compression mechanism inlet 9-9 and is compressed to increase the temperature. The heated gaseous working medium enters the cold / heat extraction heat exchanger 9-4 through the steam compression mechanism outlet 9-10 to dissipate heat, condense and liquefy. The liquefied liquid working medium flows through the H end and G end of the working medium throttling mechanism 9-3 in turn and produces a throttling and pressure reduction effect. The gas-liquid two-phase working medium after throttling and pressure reduction enters the cold / heat injection heat exchanger 9-5 again to absorb air and evaporate, and extracts heat from the phase change energy storage material 6-2 in the temperature control plate layer 6 to reduce the temperature of this layer. This cycle is repeated until the temperature in the temperature control plate layer 6 is reduced to the set value. In this mode, a closed and temperature-constant energy layer closely related to the temperature of the temperature control plate layer 6 can be formed in the inner air interlayer 7, and because the upper air outlet openable and closable air plate 8-3 on the inner wall plate and the lower air outlet openable and closable air plate 8-4 on the inner wall plate are both in a closed state in this mode, the temperature control plate layer 6 and the inner air interlayer 7 do not bear the task of handling the indoor cold load and wet load. In this mode, the air enclosed in the inner air interlayer 7 has the potential to condense and liquefy after cooling, and the condensed water will be collected through the inner air interlayer drainage groove 1-7 and discharged to the condensed water drainage riser 1-8 through the condensed water drainage series pipe 1-10.

[0044] (2) When the room temperature fluctuates instantaneously in summer and generates instantaneous cold load and instantaneous wet load, or when the room only needs to handle the wet load inside the room, the summer cooling and dehumidification mode is adopted: in this mode, the operation control of the heat activated energy system 9 and the opening strategy of the air vent openable and closable air plate 2-3 on the outer wall panel and the air outlet openable and closable air plate 2-4 on the outer wall panel are completely consistent with the summer thermal insulation mode, except that the air vent openable and closable air plate 8-3 on the inner wall panel and the air vent openable and closable air plate 8-4 under the inner wall panel are both in the open state. In this mode, the room air is relatively hotter and has a lower density, while the air inside the inner air interlayer 7 is relatively colder and has a higher density. Therefore, under the action of natural convection, the room air will enter the inner air interlayer 7 through the air vent openable and closable air plate 8-3 on the inner wall panel, where it will contact with the temperature control panel layer 6 and be cooled, condensed and dehumidified, and then flow back to the room through the air vent openable and closable air plate 8-4 under the inner wall panel, and the cycle will be repeated until the indoor air temperature and humidity meet the set requirements. In this mode, the air that continuously circulates in the inner air interlayer 7 will condense and liquefy after dehumidification and cooling, and the condensed water will also be collected through the inner air interlayer drainage groove 1-7 and discharged to the condensed water drainage riser 1-8 through the condensed water drainage series pipe 1-10.

[0045] (3) When the room is in a thermally stable state for a long time in winter, the winter heat preservation and heat insulation mode is adopted: first, the upper air vent opening and closing plate 2-3 on the outer wall panel and the lower air vent opening and closing plate 2-4 on the outer wall panel are opened, and the air vent opening and closing plate 8-3 on the inner wall panel and the lower air vent opening and closing plate 8-4 on the inner wall panel are closed. The steam compression mechanism 9-1 is started and the circulating medium reversing mechanism 9-2 is controlled so that the A end is connected to the C end and the B end is connected to the D end. At this time, the compressor absorbs air from the cold / heat extraction heat exchanger 9-4 for evaporation and extracts the low-grade heat contained in the outdoor air from the outer air interlayer 3. The gaseous medium enters the steam compression mechanism. The gaseous working medium enters the steam compression mechanism 9-1 through port 9-9 and is compressed to increase its temperature. The heated gaseous working medium enters the cold / heat injection heat exchanger 9-5 through the steam compression mechanism outlet 9-10 to dissipate heat and melt the phase change energy storage material 6-2 in the temperature control plate layer 6. After dissipating heat, the gaseous working medium condenses and liquefies and flows through the G end and the H end of the working medium throttling mechanism 9-3 in turn to produce a throttling and pressure reduction effect. The gas-liquid two-phase working medium after throttling and pressure reduction enters the cold / heat extraction heat exchanger 9-4 again to absorb air and evaporate, and extracts low-grade heat contained in the outdoor air from the outer air interlayer 3. This cycle is repeated until the temperature in the temperature control plate layer 6 is raised to the set value. In this mode, a closed and temperature-constant energy layer closely related to the temperature of the temperature control plate layer 6 can also be formed in the inner air interlayer 7, and because the upper air outlet openable and closable air plate 8-3 on the inner wall plate and the lower air outlet openable and closable air plate 8-4 on the inner wall plate are both in a closed state in this mode, the temperature control plate layer 6 and the inner air interlayer 7 do not bear the task of handling the indoor heat load. In this mode, the air that is continuously circulating in the outer air interlayer 3 has the potential to condense and liquefy after dehumidification and cooling, and the condensed water will be collected through the outer air interlayer drainage groove 1-6 and discharged to the condensed water drainage riser 1-8 through the condensed water drainage series pipe 1-9.

[0046] (4) When the room temperature fluctuates instantaneously in winter and generates an instantaneous heat load, the winter heating mode is adopted: in this mode, the operation control of the heat-activated energy system 9 and the opening strategies of the upper vents of the outer wall panel and the lower vents of the outer wall panel are completely consistent with the summer thermal insulation mode. The difference is that the upper vents of the inner wall panel and the lower vents of the inner wall panel are both in the open state. In this mode, the room air is relatively colder and denser, while the air inside the inner air interlayer 7 is relatively hotter and has a lower density. Therefore, under the action of natural convection, the room air will enter the inner air interlayer 7 through the lower vents of the inner wall panel and the lower vents of the inner wall panel. After contacting with the temperature control panel layer 6 and being heated, it will flow back to the room through the upper vents of the inner wall panel and the lower vents of the outer wall panel. This cycle repeats until the indoor air temperature reaches the set requirements. In this mode, the condensate discharge strategy in the outer air interlayer 3 is consistent with the winter thermal insulation mode.

[0047] The above is only a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
