Description

Technical Field

[0001] The present invention relates to a ventilation system, and in particular to an intelligent ventilation system for green buildings applied to the field of building ventilation technology. Background Art

[0002] With the increasing global attention to environmental protection and sustainable development, green buildings, as an energy-saving, environmentally friendly and comfortable building form, have been widely promoted and applied. As a key component of green buildings, the ventilation system plays a crucial role in maintaining indoor air quality, regulating indoor temperature and humidity, and ensuring the health and comfort of occupants.

[0003] The invention patent with the authorization announcement number CN114754448B discloses a ventilation energy-saving system for green buildings, which can ventilate from different directions, solves the problem of uneven indoor ventilation caused by fixed wind direction, and can adjust the temperature of ventilation, thus avoiding the discomfort caused by introducing hot air in summer or cold air in winter.

[0004] The invention patent with the publication number CN114754445B discloses an energy-saving ventilation system for green buildings, which realizes that when the solar panels are not in use, they can be shielded and protected, and before the solar panels are used, the surface of the solar panels can be wiped, improving the lighting efficiency of the solar panels. When ventilating the house body, the outside air can be evenly dispersed in the house, and the air volume of the air outlet can also be adjusted, improving the ventilation efficiency of the house body.

[0005] For traditional green building ventilation systems, when encountering the situation of high outdoor air humidity (such as rainy days), they often lack effective countermeasures and directly introduce high-humidity outdoor air, which is extremely likely to cause too high indoor humidity. This will not only make the occupants feel uncomfortable, but may also cause indoor items to get damp and moldy, and even breed bacteria and molds, endangering human health. Therefore, we propose an intelligent ventilation system for green buildings. Summary of the Invention

[0006] Aiming at the above-mentioned prior art, the technical problem to be solved by the present invention is: when encountering the situation of high outdoor air humidity, how the ventilation system should effectively respond to prevent the obvious increase of indoor humidity.

[0007] To solve the above problems, the present invention provides an intelligent ventilation system for green buildings, which includes a drying and air supply mechanism, an exhaust air mechanism, and a pipeline air outlet mechanism. The drying and air supply mechanism includes an air supply box, in which an air supply fan is fixedly installed. The left and right ends of the air supply box are respectively communicated with a connecting pipe and an air inlet pipe. The top end of the air supply box is communicated with an air delivery pipe, and the air delivery pipe is located on the side of the air supply fan away from the air inlet pipe. A filter screen is fixedly installed in the air supply box, and the filter screen is located between the air delivery pipe and the air supply fan. The end of the connecting pipe away from the air supply box is communicated with a sealed drying cylinder, and a storage agent mesh cylinder is arranged in the sealed drying cylinder. The storage agent mesh cylinder is a multi-porous mesh structure, and a drying agent is filled in the storage agent mesh cylinder. The end of the connecting pipe connected to the sealed drying cylinder is fixedly connected to the storage agent mesh cylinder. The top end of the sealed drying cylinder is communicated with a guide air pipe. The storage agent mesh cylinder and the guide air pipe are both located on the side of the piston plate close to the connecting pipe. First solenoid valves, second solenoid valves, and third solenoid valves are respectively arranged on the air delivery pipe, the connecting pipe, and the guide air pipe. The end of the guide air pipe away from the sealed drying cylinder is communicated with the air delivery pipe and is located on the side of the first solenoid valve away from the air supply box. An external humidity sensor is fixedly installed in the air inlet pipe, and an internal humidity sensor is fixedly installed in the sealed drying cylinder;

[0008] The drying and air supply mechanism further includes a drying control system, which includes a drying control module and a humidity analysis module. A humidity threshold is preset in the humidity analysis module. The internal humidity sensor and the external humidity sensor are both connected to the humidity analysis module in a signal manner. The humidity analysis module is connected to the drying control module in a signal manner. The drying control module is connected to the air supply fan, the internal humidity sensor, the first solenoid valve, the second solenoid valve, and the third solenoid valve in a signal manner.

[0009] In the above intelligent ventilation system for green buildings, when the outdoor air humidity is relatively high, the drying and air supply mechanism will first dry the outdoor air and then send the dried air into the room, which can effectively prevent the indoor humidity from increasing significantly due to ventilation under the condition of high outdoor air humidity.

[0010] As a further improvement of the present application, the exhaust air mechanism includes an exhaust air box, in which an exhaust air fan is fixedly installed. The drying control module is connected to the exhaust air fan in a signal manner. The left and right ends of the exhaust air box are respectively communicated with an air outlet pipe and a connecting exhaust pipe. The pipeline air outlet mechanism includes an air supply pipeline, an air supply outlet, an exhaust air pipeline, and an exhaust air outlet. The two ends of the air supply pipeline are respectively communicated with the air delivery pipe and the air supply outlet. The two ends of the exhaust air pipeline are respectively communicated with the air outlet pipe and the exhaust air outlet.

[0011] As a further improvement of the present application, the drying control system further includes a priority setting module, which is connected to the drying control module in a signal manner.

[0012] As a further improvement of the present application, the drying control system further includes a ringing reminder module, which is connected to the drying control module in a signal manner.

[0013] As a further improvement of the present application, a piston plate is arranged in the sealed drying cylinder and is slidably and sealingly connected thereto. A sealed receiving cylinder is penetrated and embedded on the outer wall of the sealed drying cylinder near one end of the air supply box. A cylinder is fixedly installed in the sealed receiving cylinder, and the output end of the cylinder is fixedly connected to the piston plate.

[0014] As a further improvement of the present application, one end of the sealed receiving cylinder connected to the sealed drying cylinder is arranged in an open shape. The electric heater is located on one side of the piston plate close to the connecting pipe. The drying control module is signal-connected to the cylinder, and a ventilation hole is opened on the outer wall of the sealed drying cylinder at the end far from the connecting pipe.

[0015] As another improvement of the present application, the drying air supply mechanism further includes an auxiliary drying component.

A spring is fixedly installed in the sealed air receiving cylinder, and one end of the spring close to the guiding pipe is fixedly connected to a sliding sealing plate that is slidably and sealingly connected to the sealed air receiving cylinder.

The drying control module is signal-connected to the fourth solenoid valve. The guiding pipe is located on the side of the second solenoid valve far from the air supply box.

[0017] In summary, through the setting of the drying air supply mechanism of the present application, when the outdoor air humidity is relatively high, the drying air supply mechanism will perform intelligent automatic adjustment. After adjustment, it will first dry the outdoor air and then send the dried air into the room, which can effectively prevent the indoor humidity from increasing significantly due to ventilation when the outdoor air humidity is relatively high, thereby causing discomfort to the occupants. This greatly improves the intelligence, practicality, and comfort of the ventilation system. And when the drying effect cannot meet the drying requirements, the drying air supply mechanism will select to continue ventilation or automatically stop ventilation according to the priority of ventilation set by the occupants, further improving the intelligence of the ventilation system and enriching the diversity of the functions of the ventilation system; through the combined setting of the piston plate, cylinder, electric heater, etc., the automatic desiccant can be dried, so that the desiccant is restored to a dry state, and during the process of drying the desiccant, the filter screen will also be automatically cleaned, further improving the intelligence and practicality of the ventilation system; through the setting of the auxiliary drying component, the contact between the hot air and the desiccant can be effectively promoted, thereby effectively improving the effect and efficiency of the drying process.

Specific implementation manners

[0029] The following will describe in detail the two implementation manners of the present application with reference to the accompanying drawings.

[0030] The first implementation manner:

[0031] Figures 1-6Disclosed is an intelligent ventilation system for green buildings, including a drying and air supply mechanism, an exhaust mechanism, and a pipeline and air outlet mechanism. The drying and air supply mechanism is used to send outdoor air into the room, the exhaust mechanism is used to discharge indoor air to the outside, and the pipeline and air outlet mechanism is used to assist the drying and air supply mechanism and the exhaust mechanism in air transportation to achieve ventilation. The drying and air supply mechanism includes a air supply box 101, in which an air supply fan 102 is fixedly installed. The left and right ends of the air supply box 101 are respectively communicated with a connecting pipe 105 and an air inlet pipe 103. The top end of the air supply box 101 is communicated with an air delivery pipe 104. The air delivery pipe 104 is located on the side of the air supply fan 102 away from the air inlet pipe 103. A filter screen 118 is fixedly installed in the air supply box 101, and the filter screen 118 is located between the air delivery pipe 104 and the air supply fan 102. The end of the connecting pipe 105 away from the air supply box 101 is communicated with a sealed drying cylinder 106. A storage agent mesh cylinder 110 is arranged in the sealed drying cylinder 106. The storage agent mesh cylinder 110 is a multi-porous mesh structure, and a drying agent 111 is filled in the storage agent mesh cylinder 110. The end of the connecting pipe 105 connected to the sealed drying cylinder 106 is fixedly connected to the storage agent mesh cylinder 110. The top end of the sealed drying cylinder 106 is communicated with a guide air pipe 113. The storage agent mesh cylinder 110 and the guide air pipe 113 are both located on the side of the piston plate 107 close to the connecting pipe 105. First solenoid valves 114, second solenoid valves 115, and third solenoid valves 116 are respectively arranged on the air delivery pipe 104, the connecting pipe 105, and the guide air pipe 113. The end of the guide air pipe 113 away from the sealed drying cylinder 106 is communicated with the air delivery pipe 104 and is located on the side of the first solenoid valve 114 away from the air supply box 101. An external humidity sensor is fixedly installed in the air inlet pipe 103, and an internal humidity sensor 112 is fixedly installed in the sealed drying cylinder 106;

[0032] The drying and air supply mechanism further includes a drying control system, which includes a drying control module and a humidity analysis module. A humidity threshold is preset in the humidity analysis module. The internal humidity sensor 112 and the external humidity sensor are both in signal connection with the humidity analysis module. The humidity analysis module is in signal connection with the drying control module. The drying control module is in signal connection with the air supply fan 102, the internal humidity sensor 112, the first solenoid valve 114, the second solenoid valve 115, and the third solenoid valve 116.

[0033] The exhaust mechanism includes an exhaust box 201, in which an exhaust fan 202 is fixedly installed. The drying control module is signal-connected to the exhaust fan 202. The left and right ends of the exhaust box 201 are respectively communicated with an air outlet pipe 203 and a continuous exhaust pipe 204. The pipeline air outlet mechanism includes a supply air pipeline, an air supply outlet, an exhaust pipeline, and an exhaust outlet. The two ends of the supply air pipeline are respectively communicated with the air delivery pipe 104 and the air supply outlet, and the two ends of the exhaust pipeline are respectively communicated with the air outlet pipe 203 and the exhaust outlet. The supply air pipeline, the air supply outlet, the exhaust pipeline, and the exhaust outlet can be arranged as required according to the situation, and the arrangement of the supply air pipeline, etc. is well-known technology to those skilled in the art and will not be elaborated here.

[0034] Under normal circumstances (i.e., when the outdoor air humidity is less than the humidity threshold), the first solenoid valve 114 is in the open state, the second solenoid valve 115 and the third solenoid valve 116 are in the closed state. During ventilation, the air supply fan 102 is started. Under the action of the air supply fan 102, outdoor air is drawn into the air supply box 101 through the air inlet pipe 103 (when the air passes through the filter screen 118, the filter screen 118 will filter the dust in the air to improve the ventilation quality and effect), and then is sent into the room through the air delivery pipe 104, the air supply duct, and the air supply outlet. At the same time, the exhaust fan 202 is started, and the indoor air can be discharged to the outside through the exhaust outlet, the exhaust duct, the air outlet pipe 203, and the connecting exhaust pipe 204, thereby realizing ventilation. During the ventilation process, the external humidity sensor is used to monitor the outdoor air humidity in real time, and the humidity data monitored by the external humidity sensor will be transmitted to the humidity analysis module in real time. When the humidity data monitored by the external humidity sensor exceeds the humidity threshold, the humidity analysis module will send a signal for intermediate drying to the drying control module, causing the drying control module to close the first solenoid valve 114, open the second solenoid valve 115 and the third solenoid valve 116, and start the internal humidity sensor 112. After the first solenoid valve 114 is closed and the second solenoid valve 115 and the third solenoid valve 116 are opened, the outdoor air drawn by the air supply fan 102 will be conveyed into the sealed drying cylinder 106 through the connecting pipe 105, and the outdoor air will first enter the storage agent mesh cylinder 110 and contact the desiccant 111 and then be discharged outside the storage agent mesh cylinder 110, so that the storage agent mesh cylinder 110 can dry the outdoor air. After the air is dried, it will enter the room through the air guide pipe 113, the air delivery pipe 104, the air supply duct, and the air supply outlet in sequence, thereby effectively preventing the indoor humidity from being too high (after the outdoor humidity drops below the humidity threshold, the humidity analysis module will send a signal to stop drying to the drying control module, causing the drying control module to close the second solenoid valve 115 and the third solenoid valve 116 and open the first solenoid valve 114 to restore the normal ventilation mode). After the internal humidity sensor 112 is opened, it will monitor the air humidity in the sealed drying cylinder 106 in real time, and the monitored humidity data will be sent to the humidity analysis module in real time. When the humidity data monitored by the internal humidity sensor 112 also exceeds the humidity threshold, the humidity analysis module will send a signal to stop ventilation to the drying control module, causing the drying control module to close the air supply fan 102 and the exhaust fan 202 to stop ventilation. At the same time, the drying control module will also close the internal humidity sensor 112, the second solenoid valve 115, the third solenoid valve 116 and open the first solenoid valve 114;

[0035] Therefore, through the setting of the drying and air supply mechanism, when the outdoor air humidity is relatively high, the drying and air supply mechanism will perform intelligent automatic adjustment. After adjustment, it will first dry the outdoor air and then send the dried air into the room, which can effectively prevent the indoor humidity from increasing significantly due to ventilation under the condition of high outdoor air humidity, thus avoiding problems such as discomfort of the occupants, and greatly improving the intelligence, practicability and comfort of the ventilation system.

[0036] The drying control system further includes a priority setting module, which is signal-connected to the drying control module. The drying control system also includes a ringing reminder module, and the drying control module is signal-connected to the ringing reminder module.

[0037] The priority setting module is used to set the priority of ventilation. The priority is divided into high and low levels. When the humidity data detected by the internal humidity sensor 112 exceeds the humidity threshold under the condition that the ventilation priority is set to the low level, the humidity analysis module will send a signal to stop ventilation to the drying control module. On the contrary, when the humidity data detected by the internal humidity sensor 112 exceeds the humidity threshold under the condition that the ventilation priority is set to the high level, the humidity analysis module will not send a signal to stop ventilation to the drying control module to continue ventilation, and the humidity analysis module will send a reminder instruction to the drying control module, causing the drying control module to activate the ringing reminder module to issue a reminder ringtone to remind relevant personnel that the humidity of the air currently sent into the room is relatively high, so that when the drying effect cannot meet the drying demand, the drying and air supply mechanism will choose to continue ventilation or automatically stop ventilation according to the priority of ventilation set by the occupants, further improving the intelligence of the ventilation system and enriching the diversity of the functions of the ventilation system.

[0038] A piston plate 107 is arranged in the sealed drying cylinder 106 and is slidably and sealingly connected thereto. A sealed receiving cylinder 108 is embedded through the outer wall of the sealed drying cylinder 106 near one end of the air supply box 101. A cylinder 109 is fixedly installed in the sealed receiving cylinder 108, and the output end of the cylinder 109 is fixedly connected to the piston plate 107. Once the drying control module receives the signal of intermediate drying from the drying control module, after the ventilation system is closed, the drying control module will control the electric heater 117 to dry the desiccant 111. During the drying process, the drying control module will control the first solenoid valve 114, the second solenoid valve 115, and the third solenoid valve 116 to be in the closed state, and then start the electric heater 117 to heat the inside of the sealed drying cylinder 106 (the heating temperature and heating duration are preset in the drying control module) to dry the moisture in the desiccant 111 and restore the desiccant 111 to the dry state, which is beneficial to the subsequent drying of the air. After the heating and drying are completed, the drying control module will turn off the electric heater 117.

[0039] The end of the sealed nano-cylinder 108 connected to the sealed drying cylinder 106 is set to an open shape, the electric heater 117 is located on the side of the piston plate 107 close to the connecting pipe 105, the drying control module is connected to the cylinder 109 signal, and the outer wall of the sealed drying cylinder 106 away from the connecting pipe 105 is provided with a vent hole 119. The drying process also includes the following operations: after the drying control module starts the electric heater 117, it will also control the cylinder 109 to push the piston plate 107 to move a preset length away from the connecting pipe 105, which can play a pressure relief role to prevent the electric heater 117 from heating the inside of the sealed drying cylinder 106. The air pressure in the area of ​​the piston plate 107 close to the connecting pipe 105 is too high, thereby improving safety. After the heating and drying is completed, the drying control module will turn on the second electric The magnetic valve 115 controls the cylinder 109 to repeatedly push and pull the piston plate 107 for a preset number of times, and there will be a preset time interval between each push and pull of the piston plate 107 by the cylinder 109. In this way, on the one hand, the hot air in the sealed drying cylinder 106 can be discharged to the outside. On the other hand, when the cylinder 109 pulls the piston plate 107 to discharge the hot air to the outside, the airflow generated will flush the filter 118 to automatically clean the dust attached to the filter 118, and because there will be a certain time interval between each push and pull, the dust that has been cleaned can be prevented from immediately re-attaching to the filter 118 to a large extent, thereby ensuring the cleaning effect. Finally, the drying control module controls the cylinder 109 to pull the piston plate 107 to reset, and the drying process is now completed.

[0040] Therefore, through the joint arrangement of the piston plate 107, the cylinder 109, the electric heater 117, etc., the automatic desiccant 111 can be dried so that the desiccant 111 is restored to a dry state. In the process of drying the desiccant 111, the filter 118 will also be automatically cleaned, further improving the intelligence and practicality of the ventilation system.

[0041] In addition, when the ventilation priority is set to a low level, when the drying control module receives a signal to stop drying from the humidity analysis module, the drying control module will also control the electric heater 117 to dry the desiccant 111, and after the drying process is completed, if the occupant does not actively turn off the ventilation system, the drying control module will control the second solenoid valve 115 and the third solenoid valve 116 to be in an open state, the first solenoid valve 114 to be in a closed state, and start the supply fan 102 and the exhaust fan 202 to continue ventilation.

[0042] The second implementation method:

[0043] Figures 7-9There is shown an intelligent ventilation system for green buildings. Different from the first embodiment, the drying and air supply mechanism further includes a drying assistance component. The drying assistance component includes a sealed air intake cylinder 401. A guiding air intake pipe 402 is connected between the sealed air intake cylinder 401 and the connecting pipe 105. A spring 404 is fixedly installed in the sealed air intake cylinder 401. One end of the spring 404 close to the guiding air intake pipe 402 is fixedly connected to a sliding sealing plate 405 that is slidably and sealingly connected to the sealed air intake cylinder 401. A fourth solenoid valve 403 is provided on the guiding air intake pipe 402. The drying control module is in signal connection with the fourth solenoid valve 403. The guiding air intake pipe 402 is located on the side of the second solenoid valve 115 away from the air supply box 101.

[0044] In this embodiment, during the drying process of the desiccant 111, after the drying control module controls the cylinder 109 to push the piston plate 107 to move a preset length away from the connecting pipe 105, before the heating and drying are completed, the drying control module will open the fourth solenoid valve 403 and control the cylinder 109 to repeatedly push and pull the piston plate 107 a preset number of times (the purpose of repeatedly pushing and pulling the piston plate 107 here is different from that after the heating and drying are completed. After the heating and drying are completed, the drying control module will still control the cylinder 109 to repeatedly push and pull the piston plate 107 to discharge hot air and automatically clean the filter net 118). During the process of the cylinder 109 repeatedly pushing and pulling the piston plate 107, hot air will repeatedly enter and exit the sealed air intake cylinder 401 through the connecting pipe 105 and the guiding air intake pipe 402, thereby effectively promoting the contact between the hot air and the desiccant 111, and further effectively improving the effect and efficiency of the drying process.

[0045] Combined with the current actual needs, the above-described embodiment adopted in this application does not limit the protection scope thereto. Within the scope of knowledge possessed by those skilled in the art, various changes made without departing from the concept of this application still fall within the protection scope of the present invention.
