Description

Technical Field

[0001] The present invention relates to the technical field of fresh air systems, and in particular to an intelligent building fresh air system. Background Art

[0002] The fresh air system is based on using special equipment to deliver fresh air into the room on one side of a closed room, and then exhausting it to the outside from the other side by special equipment, forming a "fresh air flow field" indoors, thereby meeting the needs of indoor fresh air ventilation.

[0003] The ducted fresh air system consists of a fresh air fan and duct accessories. The fresh air fan purifies the outdoor air and introduces it into the room, and the indoor air is discharged through the duct. The ductless fresh air system consists of a fresh air fan, which also purifies the outdoor air and introduces it into the room. Relatively speaking, the ducted fresh air system is more suitable for industrial or large-area office areas due to the large amount of work, while the ductless fresh air system is more suitable for home use because of its easy installation. However, when the air conditioner is turned on in summer or the heater is turned on in winter, the temperature difference between indoor and outdoor is large, and the temperature difference between the fresh air temperature and the indoor temperature is large, resulting in large temperature differences in different areas of the room. At the same time, it cannot be automatically adjusted according to the indoor humidity, and the comfort level is low. For this reason, we propose an intelligent building fresh air system.

[0018] 1. Before the fresh air enters the room, the temperature of the fresh air is adjusted by switching between cooling and heating through the semiconductor refrigeration sheet. Then, through contact with the waste heat exchange pipe, the fresh air exchanges heat with the indoor air, making the fresh air temperature close to the indoor temperature.

If the indoor humidity is lower than the set value, the atomizer will convert the water inside the atomizer slot into water mist through high-frequency vibration. When the fresh air enters the room, it will take away the water mist and increase the indoor humidity until the humidity reaches the set value. BRIEF DESCRIPTION OF THE DRAWINGS

The front end of the output shaft of the second motor 64 is rotatably connected to the dehumidifier drum 66. The dehumidifier drum 66 is rotatably connected to the interior of the dehumidifier cylinder 63. The interior of the dehumidifier cylinder 63 is fixedly connected to triangular cavities 67 distributed front and back. The triangular cavities 67 are respectively located on the left and right sides of the dehumidifier drum 66 and are in contact with each other. The lower end of the triangular cavity 67 on the rear side is provided with an air outlet duct 65, and the lower end of the triangular cavity 67 on the front side is provided with a return air assembly 68.

The air inlet mechanism 6 also includes a fresh air fan 61 and a base 62. The base 62 is provided on the rear side of the upper end of the bracket 7. The upper surface of the base 62 is fixedly connected with the fresh air fan 61. The air outlet of the fresh air fan 61 is connected to the rear end of the dehumidification cylinder 63. The input end of the fresh air fan 61 is electrically connected to the output end of the controller 9. The air inlet mechanism 6 also includes a return air assembly 68. The return air assembly 68 includes a return air duct 681 and a heating pipe 682. The lower end of the triangular cavity 67 on the front side is fixedly connected to the return air duct 681. The interior of the return air duct 681 is provided with uniformly distributed heating pipes 682. The front end of the return air duct 681 is connected to the air outlet slot 51. The input end of the heating pipe 682 is electrically connected to the output end of the controller 9. The output end of the controller 9 is connected, and the air intake mechanism 6 also includes an air intake component 69, which includes a fresh air duct 691, a radiator 692 and a semiconductor refrigeration sheet 693. A fresh air duct 691 is provided on the lower side of the front end of the dehumidification cylinder 63, and the fresh air duct 691 is connected to the rear side wall of the fresh air box 1. The front side of the fresh air duct 691 is provided with uniformly distributed semiconductor refrigeration sheets 693, and the cooling ends of the semiconductor refrigeration sheets 693 are all located inside the fresh air duct 691. The heating ends of the semiconductor refrigeration sheets 693 are all provided with radiators 692, and the radiators 692 are all located outside the fresh air duct 691. The input ends of the semiconductor refrigeration sheets 693 and the radiator 692 are electrically connected to the output end of the controller 9. The controller 9 controls the fresh air fan 61 to start, and the fresh air The machine 61 sends the external air to the dehumidifier cylinder 63. The interior of the dehumidifier cylinder 63 is provided with evenly distributed honeycomb silica gel to absorb moisture in the air. The air after dehumidification enters the fresh air duct 691. If the indoor temperature is high, the semiconductor refrigeration sheet 693 is started, and the cooling end of the semiconductor refrigeration sheet 693 reduces the air temperature. The radiator 692 dissipates heat for the heating end of the semiconductor refrigeration sheet 693. If the indoor temperature is low, the controller 9 controls the change of the current direction of the semiconductor refrigeration sheet 693. The cooling end of the semiconductor refrigeration sheet 693 located in the fresh air duct 691 is converted to the heating end. Since the heating efficiency of the semiconductor refrigeration sheet 693 is much greater than the cooling efficiency, in order to prevent the semiconductor refrigeration sheet 693 from burning out, the semiconductor refrigeration sheet 693 is divided into two groups and started at intervals.The turbid air in the room then enters the return air duct 681, and the heating pipe 682 heats the turbid air in the room. The heated air flows to the dehumidification drum 66 located inside the triangular cavity 67, taking away and drying the water vapor accumulated in the dehumidification drum 66. The motor 2 64 drives the dehumidification drum 66 to rotate, and the dehumidification and drying areas of the dehumidification drum 66 are continuously switched to improve the dehumidification efficiency.

[0032] Among them: it also includes a controller 9, the controller 9 is arranged on the right side of the fresh air box 1, the input end of the controller 9 is electrically connected to the external power supply, the input end of the motor 2 64 is electrically connected to the output end of the controller 9, and the right side of the fresh air box 1 is provided with a temperature and humidity sensor 8, and the temperature and humidity sensor 8 is electrically connected to the controller 9 in a bidirectional manner.

[0033] Wherein: it also includes a waste heat recovery mechanism 5, the waste heat recovery mechanism 5 includes an air outlet slot 51, a waste heat exchange pipe 52, a return air port 53 and a filter 54. The middle part of the bottom wall of the fresh air box 1 is provided with an air outlet slot 51, and the upper end of the fresh air box 1 is fixedly connected with a return air port 53, and evenly distributed waste heat exchange pipes 52 are fixedly connected between the return air port 53 and the air outlet slot 51. Evenly distributed filters 54 are plugged into the upper end of the return air port 53. The turbid air in the room enters each waste heat exchange pipe 52 through the return air port 53, and the filter 54 filters the dust in the turbid air in the room. The outdoor air after adjusting the temperature exchanges heat with the indoor turbid air inside the waste heat exchange pipe 52, so that the outdoor air after adjusting the temperature is close to the indoor air, reducing the temperature difference between different areas in the room.

[0034] The working principle of the intelligent building fresh air system provided by the present invention is as follows: when in use, the fresh air box 1 is placed indoors and the bracket 7 is placed outdoors. During operation, the temperature and humidity sensor 8 detects the indoor temperature and humidity and feeds back to the controller 9. The controller 9 controls the fresh air fan 61 to start. The fresh air fan 61 sends external air to the dehumidification cylinder 63. The interior of the dehumidification cylinder 63 is provided with evenly distributed honeycomb silica gel (the honeycomb silica gel can be replaced after long-term use to absorb water). It absorbs moisture in the air, and the air after dehumidification enters the fresh air duct 691. If the indoor temperature is high, the semiconductor refrigeration sheet 693 is started, the cooling end of the semiconductor refrigeration sheet 693 lowers the air temperature, and the radiator 692 dissipates heat for the heating end of the semiconductor refrigeration sheet 693. If the indoor temperature is high The controller 9 controls the change of the current direction of the semiconductor refrigeration sheet 693. The cooling end of the semiconductor refrigeration sheet 693 located inside the fresh air duct 691 is converted into the heating end. Since the heating efficiency of the semiconductor refrigeration sheet 693 is much greater than the cooling efficiency, in order to prevent the semiconductor refrigeration sheet 693 from burning out, the semiconductor refrigeration sheet 693 is divided into two groups and started at intervals. The air after adjusting the temperature enters the interior of the fresh air box 1 and enters the room from the guide chamber. The motor 1 28 is started, driving the eccentric wheel 1 25 and the eccentric wheel 2 27 to rotate. The eccentric wheel 27 rotates, driving the sliding column 10 to rotate synchronously. The sliding column 10 slides inside the slide groove 2 3 and drives the slide groove 2 3 to move back and forth up and down. The vertical connecting plate 26 moves back and forth up and down, driving the horizontal guide plate 22 to flip up and down. When the guide plate 22 is turned upside down, the vertical connecting plate 26 is driven to move back and forth in a small range. The slide groove 23 is synchronously moved back and forth in a small range outside the slide column 10. The lever of the eccentric wheel 1 25 slides inside the slide groove 1 24, driving the horizontal connecting plate 23 to move back and forth synchronously, so that the vertical guide plate 21 swings back and forth. When the vertical guide plate 21 swings back and forth, the horizontal connecting plate 23 moves back and forth in a small range at the same time. The lever of the eccentric wheel 1 25 is always located inside the slide groove 1 24, so that the air after the temperature adjustment is blown to various places in the room along with the vertical guide plate 21 and the horizontal guide plate 22. At the same time, the air after the temperature adjustment is dehumidified and is relatively dry, resulting in lower humidity. When the indoor humidity is low, the atomizing sheet 44 is started to The water in the atomizing tank 43 is converted into water mist. When the temperature-adjusted air flows into the room, it takes away the water mist, thereby increasing the indoor humidity. The turbid air in the room enters each waste heat exchange pipe 52 through the return air port 53. The filter 54 filters the dust in the turbid air in the room. The temperature-adjusted outdoor air exchanges heat with the turbid air in the room inside the waste heat exchange pipe 52, so that the temperature-adjusted outdoor air is close to the indoor air, thereby reducing the temperature difference between different areas in the room. The turbid air in the room then enters the return air duct 681. The heating pipe 682 heats the turbid air in the room. The heated air flows to the dehumidification drum 66 located inside the triangular cavity 67, takes away and dries the water vapor accumulated in the dehumidification drum 66. The motor 2 64 drives the dehumidification drum 66 to rotate.The dehumidification and drying areas of the dehumidification drum 66 are continuously switched (according to the change in the contact position between the honeycomb silica gel inside the dehumidification cylinder 63 and the triangular cavity 67, after this part of the honeycomb silica gel is dried, the honeycomb silica gel is rotated so that the undried honeycomb silica gel and the triangular cavity 67 are dehumidified again), thereby improving the dehumidification efficiency.

[0035] It is worth noting that the controller 9 disclosed in the above embodiments can use a GPRS0666 controller, the temperature and humidity sensor 8 can use a NB-I oT4G temperature and humidity sensor, the motor 28 can use an S42D110A-MA09S2 reduction motor, the motor 64 can use a GH32 reduction motor, the atomizer 44 can use a 16-110K atomizer, the fresh air fan 61 can use a DPT10-12B fresh air fan, and the semiconductor refrigeration sheet 693 can use an SP6262112L1 semiconductor refrigeration sheet.
