Description

Technical Field

[0001] The present invention relates to the technical field of intelligent laboratories, and in particular to a centralized clean air conditioning system for intelligent laboratories. Background Art

[0002] With the help of advanced artificial intelligence, Internet of Things, big data analysis and other technologies, smart laboratories have achieved automated and intelligent management of laboratories. It can not only monitor and control environmental parameters in the laboratory in real time, such as temperature, humidity, light, etc., but also intelligently control experimental equipment, optimize experimental processes, and improve experimental efficiency. In addition, smart laboratories can also collect, analyze and process experimental data, provide strong data support for scientific researchers, and promote the progress of scientific research. The clean air conditioning system is a key equipment to ensure the cleanliness of the laboratory environment. It centrally treats the air in the machine room and then delivers the clean air to each workroom, thereby ensuring that the air quality in the laboratory meets the specified standards.

[0003] A centralized clean air conditioning system disclosed in publication number CN1270136C can effectively purify indoor air. The system includes a primary filter, a blower, an air conditioning unit, a medium-efficiency filter, and an air-conditioned room, and is characterized in that an adsorption purifier and a humidifying device are added to the air conditioning system. For a centralized air conditioning system, part of the indoor return air is discharged to the outdoors, and the other part is mixed with the fresh air, and then introduced into the primary filter for purification. The treated mixed air enters the combined air conditioning unit through the blower to be treated to a suitable temperature, and then enters the medium-efficiency filter. The air treated by the medium-efficiency filter is finally sent to the air-conditioned room after passing through the adsorption purifier and the humidifying device. Utilizing the indoor air purification technology and air conditioning system involved in this invention, the concentration of indoor air pollutants in the centralized air conditioning system can be effectively reduced, and related diseases caused by various pollutants can be effectively avoided, providing people with a comfortable and healthy indoor environment.

[0004] Although the above patent completes the treatment of indoor air through the coordinated use of primary filters, blowers and air-conditioning units, the above patent cannot be flexibly adjusted according to the different air quality requirements of various workrooms in the laboratory. Since different workrooms may carry out different types of experiments or research, the required air quality standards, temperature and humidity, cleanliness and other conditions may also vary greatly. When it is impossible to adjust according to these requirements, the accuracy and reliability of the experimental results will be affected, thereby affecting the quality and efficiency of the experiment. In addition, the above patent and most of the centralized clean air conditioners on the market are mostly not equipped with emergency response functions. If the fire is not controlled in a timely and effective manner at the initial stage, the fire may quickly get out of control, resulting in serious damage to the precision instruments, equipment and research materials in the laboratory, and may even cause greater safety accidents, posing a serious threat to the safety of the laboratory and even the entire building. In addition, the air supply ducts of the air-conditioning system become a way for the fire to spread, exacerbating the expansion of the fire. Secondly, a large amount of smoke and toxic gases generated by the fire will quickly accumulate in the laboratory, seriously affecting people's breathing and vision, and even causing poisoning or suffocation.

[0075] Step 1: Open the electric valve on the fresh air duct 3, the main air blower 12, the heater / cooler 25, the humidifier 13 and the electric valve on the main air supply duct 6 through the control end 1, set the required temperature through the heater / cooler 25 through the control end 1, set the required humidity through the humidifier 13, the air inlet end of the main air supply fan 12 drives the fresh air to be transmitted from the inner cavity of the fresh air duct 3 to the inner cavity of the air inlet box 21, the fresh air passes through the primary and secondary efficiency filters 22 to filter out most of the large particle pollutants, and then passes through the electrostatic precipitator 23 to further remove the tiny particles in the air, and then is transmitted to the heater / cooler 25, the temperature of the air body is adjusted by the heater / cooler 25, and after the adjustment, the air body is transported to the humidifier 13 through the air outlet end of the main air supply fan 12, and the humidifier 13 adjusts the humidity of the air body and then transports the treated clean air out through the main air supply duct 6;

[0076] Step 2: Open the Venturi valve 74 through the controller 2 to control the air volume entering the workshop group, and the air is transmitted to the air supply box 71 through the branch air supply pipe 73, and the air is delivered to the workshop group through the air supply box 71;

[0077] Step 3: Open the blower 53, the electric valve on the exhaust pipe 54 and the electric valve on the transmission pipe 1102 through the control terminal 1, the air inlet end of the blower 53 discharges the air in the workroom group to the inner cavity of the transmission pipe 1102 through the exhaust port, the air in the workroom group is discharged to the inner cavity of the exhaust pipe 54 through the transmission pipe 1102, and then discharged to the inner cavity of the outlet pipe 55 through the air outlet end of the blower 53;

[0078] Step 4: The user sets the air quality and temperature parameter values ​​of the laboratory, sample room, processing room and analysis room through the controller 2, monitors the air quality and temperature parameters in the laboratory in real time through the air quality monitor, and uploads the parameter values ​​to the controller 2. When the air quality and temperature parameter values ​​of the laboratory, sample room, processing room or analysis room do not meet the standards set by the controller 2, the controller 2 further adjusts according to the preset standards of the laboratory, sample room, processing room and analysis room;

[0079] Step 5: If the laboratory does not meet the set standard, the secondary air supply fan 72 and the venturi valve 74 are turned on through the laboratory controller 2, and the wind speed entering the laboratory is adjusted through the secondary air supply fan 72, and the air volume entering the main laboratory 1 is adjusted through the venturi valve 74. When the temperature of the main laboratory 1 is too low, the controller 2 turns on the secondary heater 76 to heat the air body in the inner cavity of the air supply box 71 to increase the heat of the air body sent to the laboratory. When the temperature of the main laboratory 1 is too low, the controller 2 turns on the secondary cooler 75 to cool the air body in the inner cavity of the air supply box 71 to reduce the heat of the air body sent to the main laboratory 1. The air volume of the supply, return and exhaust air is adjusted by the controller 1 and the controller 2. When the main air supply fan 12 and the secondary air supply fan 72 work at the same time, the air supply volume of the air handling unit is always greater than the sum of the return air volume and the exhaust air volume. At this time, the indoor pressure of the main laboratory 1 is always maintained in a positive pressure state to prevent the untreated air from outside from entering the room through the gaps or openings, thereby further ensuring the cleanliness of the air in the laboratory.

[0080] Step 6: Detect the temperature and smoke through the temperature sensor 77 and the smoke sensor 78. When the temperature is too high and the smoke is too large, upload the detection data to the controller 2 and the controller 1. When the controller analyzes the data and finds that a fire has occurred, the controller 2 turns on the motor 1 84, the motor 2 101, the dual-axis motor 92 and the carbon dioxide releaser 916 in sequence, and the controller 1 turns off the air handling unit and the exhaust fan unit 5.

[0081] Step 7: The output shaft of the motor 1 84 drives the rotating gear 83 to rotate. Since the rotating gear 83 and the toothed plate 82 are meshed, the rotating gear 83 drives the toothed plate 82 to move, and the toothed plate 82 drives the sealing plate 81 to move to the top of the air outlet of the branch air supply pipe 73. When the sealing plate 81 completely blocks the air outlet of the branch air supply pipe 73, the controller 2 turns off the motor 1 84 to prevent smoke or flames from entering the inner cavity of the branch air supply pipe 73 and entering the air handling unit through the branch air supply pipe 73, causing pollution and damage to the branch air supply pipe 73 and the air handling unit.

[0082] Step 8: The output shaft of the second motor 101 drives the bidirectional threaded rod 102 to rotate, and the bidirectional threaded rod 102 drives the two threaded blocks 103 to move in opposite directions, and the threaded blocks 103 drive the two baffles 105 to move in opposite directions through the transmission block 104, so that the baffles 105 are away from the U-shaped placement block 91. When the baffles 105 are completely away from the U-shaped placement block 91, the second controller turns off the second motor 101, providing space for the operation of the fire extinguishing device 9;

[0083] Step nine: The two output shafts of the dual-axis motor 92 drive the two transmission plates 93 to rotate simultaneously, the transmission plate 93 drives the transmission gear 1 94 to rotate, the transmission gear 1 94 is transmitted through the transmission gear 2 97 meshing therewith, the transmission gear 2 97 on one side drives the movable plate 96 to rotate toward the side away from the transmission plate 93, the movable plate 96 drives the transmission gear 2 97 on the other side to rotate, the transmission gear 2 97 on the other side drives the transmission gear 3 910 meshing therewith to rotate, the transmission gear 3 910 drives the rotating plate 99 to move toward the side away from the movable plate 96, when the transmission plate 93, the movable plate 96 and the rotating plate 99 move, they drive the support block 911 to move in the same state, the support block 911 drives the hose 912 to move in the same state, when the transmission plate 93, the movable plate 96 and the rotating plate 99 move to a parallel state, after the hose 912 is in the same parallel state, the controller 2 turns off the dual-axis motor 92;

[0084] Step 10: The carbon dioxide releaser 916 delivers the carbon dioxide gas to the hose 912 through the connecting pipe 915 and the transmission pipe 914. The hose 912 sprays the gas through the nozzle 913, so that the oxygen concentration in the combustion area drops rapidly. When the concentration of carbon dioxide reaches a high enough level, the flame suffocates and extinguishes due to lack of oxygen, and the controller 2 closes the carbon dioxide releaser 916.

[0085] Step 11: Turn on the blower 53 through the control terminal 1, and use the above-mentioned related parts again to discharge the smoke generated by the fire.

The toothed plate (82) drives the sealing plate (81) to move to the top of the air outlet of the branch air supply pipe (73). When the sealing plate (81) completely blocks the air outlet of the branch air supply pipe (73), the controller 2 turns off the motor 1 (84), thereby preventing smoke or flames from entering the inner cavity of the branch air supply pipe (73) and entering the air handling unit through the branch air supply pipe (73), causing pollution and damage to the branch air supply pipe (73) and the air handling unit.
