Description

Technical Field

[0001] The present invention belongs to the technical field of plateau oxygen-rich environment design, and in particular relates to a thermal environment and oxygen environment coupling control system and method suitable for indoor use in plateau areas. Background Art

[0002] Hypoxia can seriously affect people's work efficiency, cognitive ability and various bodily functions. In plateau areas with an average altitude of more than 4,000 meters, the atmospheric oxygen content is only 60% of that in plain areas. Therefore, it is necessary to supply oxygen to the indoor environment to increase the indoor oxygen concentration and improve the work efficiency of indoor personnel. In addition, the temperature in high-altitude areas is lower. For every 100m increase in altitude, the temperature will drop by 0.6℃. Therefore, the plateau also has the problem of perennial low temperatures. Therefore, oxygen and heating supply to plateau buildings is the primary goal of creating an indoor environment.

[0003] In the existing technology, the air flow of the indoor ventilation method is not fully developed during the spatial flow process, which causes a great sense of blowing. At the same time, the oxygen supply method in the existing technology for plateau buildings is studied under the condition of no ventilation. The air flow has a serious impact on the oxygen supply effect of the diffuse oxygen supply method in the existing technology. The air flow will disturb the oxygen flow, thereby reducing the oxygen supply effect; at the same time, the indoor oxygen concentration also has a maximum limit. When the oxygen volume concentration exceeds 25.5%, the fire risk reaches a moderate level. Therefore, through long-term oxygen supply, the problem of excessive local oxygen concentration in the room will be caused; and in the process of indoor temperature control, while ensuring a low comfort level of blowing, it will cause the problem of hot upper and cold lower working areas of personnel, which will bring great discomfort to people, and the temperature-control air flow cannot be evenly distributed and act on the vertical direction of the room.

[0046] Preferably, the air outlet side of the oxygen supply structure 2 is located directly above the human body, and the second baffle 13 is located on the side of the human body, so that the oxygen can directly reach the human breathing zone, and thus the oxygen concentration in the human breathing zone can be accurately adjusted. The second baffle 13 can make the temperature-regulated airflow descend along its length direction, so that the ambient temperature in the height direction tends to be consistent.

[0047] Preferably, the air supply box 1 and the oxygen supply structure 2 are spaced apart so that the temperature-regulated airflow has a certain buffer area to prevent the oxygen from being dispersed by the directly rushing temperature-regulated airflow.

[0048] Preferably, the oxygen supply structure 2 is a strip-shaped structure, with an air outlet 20 provided at the bottom and an air inlet provided on the side wall, and the air inlet is connected to the oxygen production device 5 through a pipeline.

[0049] Preferably, it also includes an oxygen concentration detection device 8, and the control terminal 6 is provided with a signal receiver 7. The electrical signal of the oxygen concentration detection device 8 is connected to the signal receiver 7. Those skilled in the art can preset the oxygen concentration threshold value to achieve a self-starting oxygen supply mode.

[0050] Preferably, the first air outlet 10 and the second air outlet 11 are both slit-shaped structures, which is conducive to the temperature-controlled airflow and the first baffle 12 and the second baffle 13 forming a "Coanda effect" flow mode.

[0051] The present invention provides a method for coupling control of indoor thermal and oxygen environments in plateau areas, comprising the following steps:

[0052] The control terminal 6 controls the air supply device 3 to be normally open for regulating the indoor temperature. When the control terminal 6 controls the oxygen generator 5 to be turned on, the oxygen from the oxygen generator 5 is supplied to the oxygen supply structure 2. At the same time, the control terminal 6 controls the driving device 4 to switch the rotatable switching structure to the first air outlet 10. The first air outlet 10 sends out a temperature-controlled airflow that adheres to the first baffle 12 to form a jet, and carries the oxygen downward, completing the temperature-controlled oxygen supply.

[0053] When the control terminal 6 controls the oxygen generator 5 to be turned off, the control terminal 6 controls the driving device 4 to switch the rotatable switching structure to the second air outlet 11. The second air outlet 11 sends out a temperature-controlled airflow that adheres to the second baffle 13 to form a jet and moves downward along the second baffle 13 to complete the temperature control.

[0054] Example 1: The second air outlet 11 is attached below to supply air for heating, with an air temperature of 30°C and an air speed of 3m / s;

[0055] This embodiment takes a small space of a guardhouse in a plateau area with a size of 2m×2m×2.4m (L×W×H) as the research object. A table and a computer are distributed in the building space, and a human model is arranged in front of the table. An air supply box 1 is installed on the wall on the left side of the human body. At this stage, the second air outlet 11 is opened. The second air outlet 11 is a slit-type air outlet with an aspect ratio of 24:1, an air supply speed of 3m / s, an air supply temperature of 30°C, and an initial temperature of the room of 8.1°C. The uniformity of the temperature distribution in the personnel working area under the air supply heating mode attached below the second air outlet 11 is significantly higher than the temperature distribution under the split air conditioner air supply mode. Figure 6In addition, by calculating the local dissatisfaction rate (LPD) and the personnel's wind sensation (DR), that is, by calculating the LPD value and DR value of the personnel's work area, the thermal comfort feeling brought by the attached air supply mode and the split air supply mode of the air conditioner is compared. The calculation formulas of the two evaluation indicators are as follows:

[0056] When the air temperature difference between the head and ankle vertical height is less than 8.0℃, the local dissatisfaction rate LPD caused by the vertical temperature gradient can be determined by the following formula:

[0057] ;

[0058] in, The vertical air temperature difference between the head and ankles, °C. The "Standard for Evaluation of Indoor Thermal and Humid Environments in Civil Buildings" stipulates that an LPD value below 10% meets the requirements of Level I, between 10% and 25% meets the requirements of Level II, and greater than 25% meets the requirements of Level III.

[0059] ;

[0060] Where t is the air temperature at the measurement point; v is the local air velocity at the measurement point. When v < 0.5 m / s, v = 0.5 m / s. Tu is the turbulence intensity. Studies have shown that a DR of 40% is reasonable for mixed ventilation, underfloor air supply, and TAC task air conditioning. ASHRAE stipulates that DR at the measurement point should not be greater than 20% of the allowable value. ISO7730 stipulates that DR should not exceed 10% in Class A spaces and should not exceed 20% in Class B spaces. To ensure good thermal comfort for personnel, the DR value should be as small as possible.

[0061] The attached air supply mode of the second air outlet 11 creates a higher blowing sensation in the initial stage of heating than the split air conditioner. However, as heating continues, the air jet flow develops, and the blowing sensation in the working area is lower than that of the split air conditioner. Figure 4 In addition, the attached air supply of the second air outlet 11 uses the momentum of the air supply to overcome the influence of thermal buoyancy and delivers the hot air flow directly to the bottom of the room, avoiding the problem of excessive temperature difference between the head and feet caused by the split air conditioner supply, thereby effectively reducing the local dissatisfaction rate in the work area, such as Figure 5 、 Figure 6 shown.

[0062] Example 2: The first air outlet 10 is attached to supply air for heating and oxygen in the air flow path, with an air supply temperature of 30°C, an air supply speed of 3m / s, an oxygen supply volume of 10L / min, and an oxygen supply concentration of 90%.

[0063] In this embodiment, after 10 minutes of heating, the upper attached air supply method of opening the first air outlet 10 is used to provide heat and oxygen on the air flow path. The model is still a small space of a 2m×2m×2.4m (L×W×H) plateau area sentry box. A table and a computer are distributed in the building space, and a human model is arranged in front of the table. An air supply box 1 is installed on the left wall of the human body. The air outlet of the first air outlet 10 is a slit-type air outlet with an aspect ratio of 24:1, an air supply speed of 3m / s, and an air supply temperature of 30°C. An oxygen supply structure 2 is placed on the air flow path just above the human body. The air outlet of the oxygen supply structure 2 is a slit-type oxygen outlet suitable for the attached air flow shape, with an aspect ratio of 12:1, an oxygen supply concentration of 90%, and an oxygen supply volume of 10L / min. In this embodiment, the oxygen supply effect of the diffuse oxygen supply method under the split air conditioner is compared, and the oxygen supply efficiency is calculated by , which refers to the ability of oxygen to be transported from the oxygen outlet to the target breathing zone. The oxygen supply efficiency is used to evaluate the ability of the oxygen supply method to create a local oxygen environment. The calculation formula is as follows:

[0064] ;

[0065] in, Indicates the average oxygen concentration in the target breathing zone, Indicates the oxygen supply concentration at the oxygen outlet. Indicates the initial oxygen concentration in the hypoxic room. The closer the value is to 1, the closer the oxygen concentration in the target breathing zone is to the oxygen supply concentration at the oxygen outlet, and the higher the oxygen supply efficiency.

[0066] Thus, the oxygen supply efficiency of each oxygen supply method under this embodiment can be calculated. After 300s of oxygen supply, the oxygen supply efficiency of the oxygen supply method in the upper attached air flow path is 12%, which is much higher than the oxygen supply efficiency of the diffuse oxygen supply method in the room ventilation mode. Figure 7 Moreover, oxygen supply along the air flow path can effectively avoid unnecessary diffusion of oxygen and directly deliver oxygen to the breathing zone of personnel. The oxygen concentration created in the breathing zone is 28%, which is much higher than the oxygen concentration created by the diffuse oxygen supply method in the breathing zone. Figure 7 、 Figure 8 、 Figure 9 In addition, the "upper attached air supply + path oxygen supply" mode used in the oxygen supply stage produces a breeze in the personnel work area, which is significantly different from the split-type air conditioner. Figure 10 shown.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
