Description

Technical Field

[0001] This invention relates to the field of building curtain wall technology, and in particular to a temperature control system and method for a breathing curtain wall. Background Technology

[0002] Breathing curtain walls, also known as double-layer curtain walls, double-layer ventilated curtain walls, thermal aisle curtain walls, etc., consist of inner and outer curtain walls, forming a relatively enclosed space between them. Air can enter from the lower air inlet and leave this space from the upper air outlet. This space is constantly in a state of air flow, and heat flows in this space.

[0003] Breathing curtain walls consist of two layers of glass curtain walls, inner and outer. Compared to traditional curtain walls, their biggest feature is the ventilation layer formed between the two layers. Due to the circulation or circulation of air in this layer, the temperature of the inner curtain wall approaches the indoor temperature, reducing the temperature difference. Therefore, it saves 42%-52% energy during heating and 38%-60% during cooling compared to traditional curtain walls. Furthermore, the use of double-layer curtain walls significantly improves the overall sound insulation. Based on their structural characteristics and ventilation principles, double-layer curtain walls can be classified into various forms, including external circulation (natural ventilation), internal circulation (mechanical ventilation), internal and external circulation (hybrid ventilation), as well as closed and open types.

[0004] Chinese Patent Application Publication No. CN104453039A discloses a composite temperature-controlled curtain wall with a three-layer glass structure and its temperature control method. In this invention, louvered grille vent assemblies are installed at the upper and lower ends of both the inner and outer glass curtain walls; an independent inner interlayer heat exchange channel is formed between the inner glass curtain wall and the middle partition glass curtain wall; an independent outer interlayer heat exchange channel is formed between the outer glass curtain wall and the middle partition glass curtain wall; semiconductor thermoelectric temperature control units are evenly distributed on the middle partition glass curtain wall; the environmental monitoring system consists of multiple temperature sensors, providing real-time temperature monitoring data of the target environment to the temperature reading module in the microcontroller control module; the semiconductor thermoelectric temperature control units are controlled by the microcontroller control module.

[0005] It can be seen that the above technical solution does not consider configuring independent circulation adjustment branches and zoned monitoring for each room, and cannot adapt to the personalized temperature control needs of different rooms, resulting in local temperature control imbalance and thus the poor temperature control efficiency of the breathing curtain wall. Summary of the Invention

[0006] To address this, the present invention provides a multi-layer co-extrusion molding method for composite membrane materials used in buildings, which overcomes the problem in the prior art that does not consider configuring independent circulation adjustment branches and zoned monitoring for individual rooms, making it unable to adapt to the personalized temperature control needs of different rooms, resulting in local temperature control imbalance and thus poor temperature control efficiency of the breathing curtain wall.

[0007] To achieve the above objectives, in one aspect, the present invention provides a temperature control system for a breathing curtain wall, comprising: The internal circulation module is used to introduce indoor air into the cavity of the breathing curtain wall, exchange heat, and then return it to the room. The external circulation module is used to introduce outdoor air into the cavity of the breathing curtain wall, exchange heat, and then exhaust it back to the outside. The data acquisition module is used to collect indoor temperature and carbon dioxide concentration values ​​of several rooms under the condition of executing a preset duration in the initial operation mode, as well as the current value of the outer fan. The data processing module is used to obtain the temperature control stability characterization value based on the indoor temperature value of the room, to obtain the current deviation of the room with abnormal temperature based on the current value of the outer fan, and to obtain the indoor disturbance characterization value based on the indoor temperature and carbon dioxide concentration of the room with abnormal temperature. The control module is used to determine whether the room temperature control meets the preset standard based on the temperature control stability characterization value; The optimization module is used to determine the temperature control optimization strategy for the room with abnormal temperature when the temperature control of the breathing curtain wall does not meet the preset standard based on the current deviation of the room with abnormal temperature, and to determine the temperature control optimization strategy for the room with abnormal temperature a second time based on the indoor interference characterization value of the room with abnormal temperature. The temperature control optimization strategy includes issuing a fault alarm for the external circulation module, increasing the preset opening degree of all windproof valves in the room with abnormal temperature, or opening the inner circulation branch corresponding to the room with abnormal temperature while keeping the outer circulation branch open.

[0008] Furthermore, the inner circulation module includes inner circulation branches corresponding to several rooms, each inner circulation branch being adapted to the breathing curtain wall inner structure of the corresponding room, and the inner circulation branch including an independent inner fan and an airflow guiding valve. The external circulation module includes external circulation branches corresponding to several rooms. Each external circulation branch is adapted to the breathing curtain wall external structure of the corresponding room. The external circulation branch includes an independent external fan and a windproof valve.

[0009] Furthermore, the initial operating mode is to control all outer circulation branches of the outer circulation module to open, control all inner circulation branches of the inner circulation module to close, set all outer fans to run at a preset speed, and set all windproof valves to open at a preset opening degree.

[0010] Furthermore, the control module determines that the temperature control of the breathing curtain wall is at risk of not meeting the preset standard based on the temperature control stability characterization value being greater than or equal to the first preset temperature control stability threshold and less than the second preset temperature control stability threshold, and increases the preset speed of the corresponding outer fan of the room with abnormal temperature based on the difference between the temperature control stability characterization value and the first preset temperature control stability threshold.

[0011] Furthermore, the temperature control stability characterization value is determined based on the absolute difference between the indoor temperature of several rooms that have been collected and operated in the initial operating mode for a preset time and the preset indoor temperature.

[0012] Furthermore, in response to the temperature control of the breathing curtain wall failing to meet the preset standard, the optimization module determines a temperature control optimization strategy for the room with abnormal temperature when the temperature control of the breathing curtain wall fails to meet the preset standard, based on the fact that the current deviation of the room with abnormal temperature is less than the preset current deviation. The room with abnormal temperature is a room where the absolute difference between the indoor temperature and the preset indoor temperature is greater than the absolute difference of the preset temperature. The temperature control of the breathing curtain wall does not meet the preset standard, which is determined based on the temperature control stability characterization value being greater than or equal to the second preset temperature control stability threshold.

[0013] Furthermore, the current deviation is determined based on several current values ​​of the outer fan of the room with abnormal temperature during operation at a preset speed, which is the ratio of the standard deviation to the arithmetic mean of the several current values.

[0014] Furthermore, in response to the indoor interference characterization value being less than a preset indoor interference characterization value, the optimization module increases the preset opening degree of all windproof valves in the room with abnormal temperature based on the difference between the preset indoor interference characterization value and the indoor interference characterization value. If the indoor interference characterization value is greater than or equal to the preset indoor interference characterization value, the optimization module will activate the inner circulation branch corresponding to the room with abnormal temperature while keeping the outer circulation branch open.

[0015] Furthermore, the indoor disturbance characterization value is determined based on the indoor temperature sequence and indoor carbon dioxide concentration sequence synchronously collected at a second preset frequency within a preset time period.

[0016] On the other hand, the present invention provides a temperature control method for a temperature control system using a breathing curtain wall, comprising: Step S1: Control the breathing curtain wall to execute the initial operation mode, control all outer circulation branches of the outer circulation module to open, control all inner circulation branches of the inner circulation module to close, set all outer fans to run at a preset speed, set all windproof valves to open at a preset opening degree, and continue to run for a preset time. Step S2: After the preset time period ends, the indoor temperature of several rooms is collected to obtain the temperature control stability characterization value; based on the temperature control stability characterization value, it is determined whether the temperature control of the breathing curtain wall meets the preset standard. Step S3: When it is determined that the temperature control of the breathing curtain wall is at risk of not meeting the preset standard, increase the preset speed of the corresponding outer fan of the room with abnormal temperature. Step S4: When it is determined that the temperature control of the breathing curtain wall does not meet the preset standard, the temperature control optimization strategy for the temperature abnormal room is determined based on the current deviation of the temperature abnormal room. The temperature control optimization strategy is to determine the temperature control optimization strategy for the temperature abnormal room a second time based on the indoor interference characterization value of the temperature abnormal room or to issue a fault alarm for the external circulation module equipment.

[0017] Compared with existing technologies, the beneficial effects of this invention are as follows: This invention predicts temperature control risks by quantifying the overall dispersion of temperature in each room and makes a holistic judgment; after confirming an anomaly, it eliminates the possibility of equipment malfunction by analyzing the fan current characteristics; finally, by utilizing the physical correlation between temperature and carbon dioxide concentration changes, it intelligently distinguishes whether the heat comes from indoor human activities or outdoor environmental changes, thereby automatically selecting to activate internal circulation for heat dissipation or adjust external circulation for heat resistance, adapting to the personalized temperature control needs of different rooms due to differences in human density and usage scenarios, effectively improving the temperature control stability and accuracy of the breathing curtain wall, thereby improving the temperature control efficiency of the breathing curtain wall.

[0018] Furthermore, by refining the internal and external circulation modules into independent branches corresponding to each room, this invention provides physical protection for independent and parallel temperature control in different areas of the building. Each room's curtain wall unit can be controlled independently, thereby achieving a precise response to the uneven distribution of the building's heat load and avoiding the local overheating and overcooling phenomena caused by traditional centralized control, thus improving overall comfort.

[0019] Furthermore, by initially activating only the external circulation and deactivating the internal circulation, this invention establishes a stable and controllable initial thermodynamic and airflow state for the entire temperature control system, reducing equipment startup shock and operational risks. At the same time, this mode clarifies the baseline operating point before the system performs any intelligent adjustments, ensuring that all subsequent adjustment commands for fan speed and valve opening have a clear relative reference origin, thereby guaranteeing the clarity and traceability of the control logic.

[0020] Furthermore, this invention categorizes temperature control performance into three levels—compliant, risky, and non-compliant—by classifying temperature control stability characteristics. By defining the temperature control stability characteristic as the standard deviation of the deviation between each room's temperature and the set target value, the stability of the control system is transformed into a quantifiable indicator. When the characteristic value is less than a first threshold, it indicates good overall control and energy-saving operation. When the characteristic value is between the first and second thresholds, the system is deemed to be in a risky temperature control state. Although no room temperature is severely exceeding the standard, overall consistency has shown a downward trend. The system initiates preventative adjustments, increasing the speed of the outer fan in rooms with large positive temperature deviations to locally enhance heat dissipation and curb the trend of increasing overall dispersion. This effectively avoids drastic, high-energy-consumption remedial adjustments caused by local overheating, improving the uniformity and steady-state maintenance of the indoor thermal environment, and realizing a shift from passive correction to active stability maintenance. When the characteristic value exceeds the second threshold, it indicates that the system control has significantly become unstable, triggering a deeper adjustment process, thereby improving the reliability of the assessment.

[0021] Furthermore, this invention constructs an anomaly tracing mechanism with current deviation as the core, enabling accurate differentiation between equipment faults and environmental interference. When the current deviation exceeds the standard, a fault alarm is directly issued to avoid misjudging the fault as environmental interference. When the current deviation meets the standard, the type of environmental interference is further subdivided through indoor interference characterization values, thereby achieving timely early warning of faults and accurate location of environmental interference.

[0027] The temperature control system for a breathing curtain wall according to an embodiment of the present invention includes: The internal circulation module is used to introduce indoor air into the cavity of the breathing curtain wall, exchange heat, and then return it to the room. The external circulation module is used to introduce outdoor air into the cavity of the breathing curtain wall, exchange heat, and then exhaust it back to the outside.

[0028] It should be noted that the data in this embodiment are all results obtained through preliminary experiments before this test using the method described in this invention. Each preset value can be adjusted according to the specific application, as long as the method described in this invention can clearly define different specific situations in the single-item judgment process through the acquired values. The preset values ​​set in this embodiment are all obtained from preliminary experiments, including the correction coefficients, which were also selected through experimental verification.

[0029] Specifically, the breathing curtain wall is a double-layer curtain wall structure, including an outer single-layer glass curtain wall, an inner single-layer glass curtain wall, and a cavity formed between the outer and inner curtain walls. The bottom and top of the outer curtain wall are respectively provided with an outer air inlet and an outer air outlet, and the bottom and top of the inner curtain wall are respectively provided with an inner air inlet and an inner air outlet, so as to realize the exchange of air between the cavity and the indoor and outdoor air.

[0030] Specifically, the indoor temperature value is obtained by installing a wall-mounted PT100 temperature sensor on the wall at a height of 1.5m above the ground in the center of each room; a non-intrusive AC current sensor (such as an open-type current transformer) is integrated into the fan power distribution circuit of the outer circulation branch corresponding to each room to collect the current value of the outer fan; a carbon dioxide concentration sensor is installed at a position adjacent to the wall-mounted PT100 temperature sensor in the room with abnormal temperature to obtain the carbon dioxide concentration.

[0031] Specifically, there are no restrictions on the specific structure of the data processing module, control module, and optimization module. They themselves and their units can be composed of logic components, including field-programmable components, computers, or microprocessors in computers.

[0032] Specifically, the inner circulation module includes inner circulation branches corresponding to several rooms. Each inner circulation branch is adapted to the inner structure of the breathing curtain wall of the corresponding room. The inner circulation branch includes an inner fan and an airflow guiding valve. For each room, an inner circulation branch is set up. The inner circulation branch includes: an air outlet opened on the upper part of the inner wall of the room, an air exhaust outlet opened on the lower part of the inner curtain wall, an inner fan whose air inlet end is connected to the air inlet through a first air duct and whose air outlet end is connected to the air exhaust outlet through a second air duct, and an airflow guiding valve installed on the first air duct.

[0033] Working path of the inner circulation module: When the inner circulation branch is started, the indoor air is pressurized by the inner fan from the exhaust vent and sent to the cavity of the breathing curtain wall. The indoor air flows from bottom to top in the cavity to complete heat exchange and then returns to the room from the exhaust vent.

[0034] The external circulation module includes external circulation branches corresponding to several rooms. Each external circulation branch is adapted to the outer structure of the breathing curtain wall of the corresponding room. Each external circulation branch includes an independent external fan and a windproof valve. An external circulation branch is provided for each room. The external circulation branch includes: an outdoor fresh air inlet located at the lower part of the outer curtain wall; a windproof valve installed at the outdoor fresh air inlet; and an external fan connected to the air outlet side of the windproof valve via a duct. The fan is used to send outdoor air into the cavity of the breathing curtain wall. After heat exchange, the air is discharged from an exhaust vent located at the upper part of the outer curtain wall. The exhaust vent can be opened and closed.

[0035] Specifically, the initial operating mode is to control all outer circulation branches of the outer circulation module to open and control all inner circulation branches of the inner circulation module to close; set all outer fans to run at a preset speed of 1100 rpm and set all windproof valves to open at a preset opening degree of 60°.

[0036] Specifically, the control module determines whether the temperature control of the breathing curtain wall meets a preset standard based on the room's temperature stability characteristic value. If the temperature control stability indicator value is less than the first preset temperature control stability threshold of 0.5℃, it is determined that the temperature control of the breathing curtain wall meets the preset standard, and the initial operation mode continues to be executed. If the temperature control stability indicator value is greater than or equal to the first preset temperature control stability threshold and less than the second preset temperature control stability threshold of 1.1℃, it is determined that the temperature control of the breathing curtain wall is at risk of not meeting the preset standard, and the preset speed of the corresponding outer fan of the room with abnormal temperature is increased according to the difference between the temperature control stability indicator value and the first preset temperature control stability threshold. If the temperature control stability characterization value is greater than or equal to the second preset temperature control stability threshold, it is determined that the temperature control of the breathing curtain wall does not meet the preset standard. The optimization module determines the temperature control optimization strategy for the temperature abnormal room when the temperature control of the breathing curtain wall does not meet the preset standard based on the current deviation of the temperature abnormal room. The room with abnormal temperature is a room where the absolute difference between the indoor temperature and the preset indoor temperature of 25°C is greater than the absolute difference of the preset temperature of 3°C.

[0037] Specifically, the temperature control stability characterization value is compared with the first and second preset thresholds to distinguish three fundamentally different operating states: stable, metastable (risky), and unstable (not up to standard). In the stable state, the current operating parameters are maintained; in the metastable state, local deterioration units are fine-tuned to curb the trend of increasing overall dispersion; and in the unstable state, a temperature control optimization strategy is formulated.

[0038] Specifically, the first preset temperature control stability threshold ranges from [0.2℃ to 0.6℃], and the second preset temperature control stability threshold ranges from [0.9℃ to 1.3℃]. Preferably, the first preset temperature control stability threshold is 0.5℃ and the second preset temperature control stability threshold is 1.1℃.

[0039] Specifically, the temperature control stability characterization value is a quantitative statistical indicator used to evaluate the control accuracy and stability of the breathing curtain wall temperature control system in the spatial dimension, which is the degree of stability of the indoor temperature fluctuation of each room relative to the preset target temperature. The more drastic the fluctuation of the indoor temperature of each room, the better.

[0040] Specifically, the increase in the preset rotation speed of the outer fan corresponding to the room with abnormal temperature is positively correlated with the difference between the temperature control stability characterization value and the first preset temperature control stability threshold. The positive correlation can be linear or nonlinear. The linear slope of the linear positive correlation is not specifically limited. It can be understood that the greater the difference between the temperature control stability characterization value and the first preset temperature control stability threshold, the greater the increase in the preset rotation speed of the outer fan corresponding to the room with abnormal temperature.

[0041] Specifically, the process of obtaining the temperature control stability characterization value includes: After running in the initial operating mode for a preset duration of 30 minutes, the indoor temperature of several rooms was collected; Calculate the absolute difference between the indoor temperature and the preset indoor temperature of 25°C, and record it as the absolute temperature difference; The standard deviation of the absolute temperature difference is denoted as the temperature control stability characterization value.

[0042] Specifically, the optimization module determines a temperature control optimization strategy for rooms with abnormal temperatures when the temperature control of the breathing curtain wall does not meet preset standards, based on the current deviation of the room with abnormal temperature. If the current deviation is less than the preset current deviation of 0.17, the temperature control optimization strategy for the temperature-abnormal room is determined a second time based on the indoor interference characterization value of the temperature-abnormal room. If the current deviation is greater than or equal to the preset current deviation, an external circulation module equipment fault alarm will be issued.

[0043] Specifically, after the temperature control system malfunctions, the first step is to inspect the critical actuator, the fan. By analyzing the current deviation, the problem can be quickly distinguished between environmental interference and equipment failure, thus determining whether the subsequent process involves complex environmental analysis or a simple fault alarm.

[0044] In this embodiment, the preset current deviation value is 0.17. This preset current deviation value is determined based on statistical analysis of historical current data of the outer fan under healthy and stable operating conditions, taking the average value within a reasonable range. However, the above value is not limited to this. Those skilled in the art can adaptively adjust the preset current deviation value according to the specific fan model, load characteristics, and operating environment.

[0045] Specifically, the process of obtaining the current deviation includes: During the operation of the outer fan of the room with abnormal temperature at a preset speed of 1100 rpm for 20 seconds, the current values ​​of several of the outer fans are collected at a first preset frequency of 10 Hz. Calculate the standard deviation and the arithmetic mean of the current values, respectively. The ratio of the standard deviation of the current value to the arithmetic mean of the current values ​​is denoted as the current deviation of the room with abnormal temperature.

[0046] Specifically, the optimization module determines the temperature control optimization strategy for the room with abnormal temperature a second time based on the indoor disturbance characterization value of the room with abnormal temperature, wherein, If the indoor disturbance characterization value is less than the preset indoor disturbance characterization value of 0.6, then the preset opening degree of all windproof valves in the room with abnormal temperature is increased according to the difference between the preset indoor disturbance characterization value and the indoor disturbance characterization value. If the indoor disturbance characterization value is greater than or equal to the preset indoor disturbance characterization value, the inner circulation branch corresponding to the room with abnormal temperature will be opened while the outer circulation branch is kept open. In this embodiment, the inner fan speed is 700 rpm and the airflow guide valve opening degree is 30°.

[0047] Specifically, the increase in the preset opening degree of all the windproof valves in the room with abnormal temperature is positively correlated with the difference between the preset indoor disturbance characterization value and the indoor disturbance characterization value. The positive correlation can be linear or nonlinear. The linear slope of the linear positive correlation is not specifically limited. It can be understood that the greater the difference between the preset indoor disturbance characterization value and the indoor disturbance characterization value, the greater the increase in the preset opening degree of all the windproof valves in the room with abnormal temperature.

[0048] Specifically, the preset indoor interference characterization value ranges from [0.5, 0.9]. Those skilled in the art will understand that the higher the requirement for the accuracy of interference source differentiation, the closer the preset indoor interference characterization value should be to the upper limit of the range, in order to reduce the possibility of misjudging outdoor interference as indoor interference and make the control strategy more conservative and accurate. Conversely, for scenarios where the accuracy of interference source differentiation is not required, a value closer to the lower limit of the range can be used to make the system more sensitive to indoor personnel activities. In this embodiment, the preset indoor interference characterization value is 0.6, but the above value is not limited to this. Those skilled in the art can adjust the above value according to actual needs.

[0049] Specifically, the indoor disturbance characterization value is a quantification of the covariant relationship between the rate of temperature change and the rate of carbon dioxide concentration change. The larger the value, the stronger the synergy between the temperature rise and the increase in carbon dioxide concentration, which is more consistent with the heat generation characteristics of indoor human activities. The smaller the value, the more the temperature rise is related to outdoor environmental factors. When the characterization value is less than the preset threshold (determined as outdoor thermal interference), the opening of the windproof valve is increased to enhance the external circulation heat dissipation capacity, blocking or eliminating heat from the outside. When the characterization value is greater than or equal to the preset threshold (determined as indoor thermal interference), the inner circulation branch is opened to achieve the coordination of the inner and outer circulation branches, forming a coordinated operation mode in which the external circulation ensures basic fresh air and the internal circulation mainly removes heat generation.

[0050] Specifically, the process of obtaining indoor disturbance characterization values ​​includes: Within a preset duration of 30 minutes, the indoor temperature sequence and indoor carbon dioxide concentration sequence of the room with abnormal temperature are collected synchronously at a second preset frequency of 5 minutes / time. An indoor disturbance curve is constructed with the rate of change of indoor carbon dioxide concentration on the x-axis and the rate of change of indoor temperature on the y-axis. The area difference between the indoor disturbance curve and the preset indoor disturbance curve is denoted as the indoor disturbance characterization value. The area difference between the indoor disturbance curve and the preset indoor disturbance curve is obtained by trapezoidal method numerical integration. The input of the trapezoidal method numerical integration is the temperature change rate sequence, the carbon dioxide concentration change rate sequence, and the preset indoor disturbance curve equation. Its output is a scalar value characterizing the overall deviation between the two curves, i.e., the indoor disturbance characterization value. The directed area of ​​the trapezoid formed by the adjacent data points of the indoor disturbance curve and the preset straight line is calculated sequentially and then accumulated and processed by absolute value. This is a common technique in the field for obtaining the area of ​​a closed region when given a data point sequence and a reference curve. The specific calculation process is not described in detail.

[0051] In this embodiment, the process of obtaining the preset indoor disturbance curve includes: Select several rooms and collect historical data on indoor temperature and carbon dioxide concentration in these rooms synchronously and continuously during peak office hours on weekdays (9:00 a.m. to 5:00 p.m.) for 5 consecutive working days. Analyze the large amount of historical data collected to select continuous time periods in which carbon dioxide concentration shows a steady upward trend and temperature rises synchronously, such as data segments that last for 45 minutes each time. Calculate the temperature change (ΔT) and carbon dioxide concentration change (ΔC) per minute within each data segment to obtain a series of (ΔC, ΔT) data points; The data points calculated from all the segments are aggregated to form a large dataset; Linear regression analysis was performed on all the data points collected above using the least squares method to fit a straight line, which is the preset indoor disturbance curve.

[0052] In this embodiment, the preset indoor disturbance curve is ΔT=0.01×ΔC.

[0053] On the other hand, the temperature control method of the temperature control system for a breathing curtain wall, as applied in this embodiment of the invention, includes: Step S1: Control the breathing curtain wall to execute the initial operation mode, control all outer circulation branches of the outer circulation module to open, control all inner circulation branches of the inner circulation module to close, set all outer fans to run at a preset speed of 1100 rpm, set all windproof valves to open at a preset opening of 60°, and continue to run for a preset duration of 30 minutes. Step S2: After the preset time period ends, the indoor temperature of several rooms is collected to obtain the temperature control stability characterization value; based on the temperature control stability characterization value, it is determined whether the temperature control of the breathing curtain wall meets the preset standard. Step S3: When it is determined that the temperature control of the breathing curtain wall is at risk of not meeting the preset standard, increase the preset speed of the corresponding outer fan of the room with abnormal temperature. Step S4: When it is determined that the temperature control of the breathing curtain wall does not meet the preset standard, the temperature control optimization strategy for the temperature abnormal room is determined based on the current deviation of the temperature abnormal room. The temperature control optimization strategy is to determine the temperature control optimization strategy for the temperature abnormal room a second time based on the indoor interference characterization value of the temperature abnormal room or to issue a fault alarm for the external circulation module equipment.

[0054] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
