The technical scheme of the embodiment of the present invention will be described in detail below with reference to the accompanying drawings.
The present embodiment provides a home air conditioning ventilation system for blocking an airborne infectious disease, comprising: an air conditioner indoor unit; the micro-static filter is arranged at an air return opening of the air conditioner indoor unit. The micro-static filter is arranged at the return air inlet of the indoor unit of the air conditioner, and compared with the air conditioner with only one layer of coarse filter screen, the filter efficiency is improved by thousands of times, harmful particles such as PM2.5 and the like are filtered, and meanwhile, indoor air can be disinfected, and the efficiency is equivalent to medium-efficiency F7.
In this embodiment, the method further includes: and the inlet of the fresh air system is arranged on the outer wall. In order to ensure the safety of the same room as the infectious patient, an independent fresh air system is arranged according to the user, and the inlet is arranged on the outer wall.
In this embodiment, the method further includes:
and the total heat exchanger is used for exchanging indoor exhaust air with fresh air and then connecting the indoor exhaust air and the fresh air into the double-layer louver air supply opening to be fed into a room.
Referring to fig. 1, the total heat exchanger includes: an exchanger body 1; an internal air supply opening 2; an air supply duct 3 having a first end connected to the exchanger main body 1 and the other end connected to the internal air supply opening 2; an exhaust duct 4, a first end of which is connected to the exchanger main body 1; an indoor return air opening 5; an indoor air suction duct 6, a first end of which is connected to the exchanger body 1 and a second end of which is connected to the indoor return air opening 5; an outdoor fresh air pipeline 7, the first end of which is connected with the main body 1 of the exchanger.
In this embodiment, the exhaust duct 4 is provided with an insulation layer 8.
In this embodiment, the outdoor fresh air pipeline 7 is provided with an insulation layer 8.
In this embodiment, the air supply duct 3 is flexibly connected to the exchanger main body 1.
In this embodiment, the indoor air intake pipe 6 is flexibly connected to the exchanger main body 1.
In this embodiment, the exchanger body 1 is fixed to the ceiling by means of ceiling suspension bolts 9.
In this embodiment, the fresh air inlet is provided with an initial filter and a medium-efficiency filter, and the exhaust outlet is provided with a high-efficiency filter.
Some houses with fresh air systems are generally connected with a double-layer shutter air supply opening to be sent into a room after indoor exhaust air exchanges heat with fresh air through a total heat exchanger. Because the total heat recovery mode is adopted, cross infection of exhaust air and fresh air cannot be avoided, after an exhaust outlet is closed during infection, only the fresh air or the direct expansion type fresh air processor is supplied, and outdoor air is sent into a room after cold and hot treatment, so that the fresh air system can meet the sanitary requirements of people, and the condition that the energy consumption of an air conditioner is increased due to the fact that the outdoor hot air (cold air in winter) in summer directly enters the room is avoided. The air conditioning ventilation system of each household is modified and adjusted as follows: firstly, arranging a micro-static air purifier; second, closing the air outlet of the room, leading the exhaust air of the bathroom to the roof for filtering and then discharging; thirdly, the check valves on the toilet exhaust fan and the fume exhaust pipeline are ensured to be installed.
And a micro-static purifier is arranged on an air return port of the indoor unit of the multi-split air conditioner to sterilize indoor air. The traditional high-voltage static electricity can generate ozone harmful to people, oxidize the lungs of people, and the problem is solved by micro static electricity. The primary purification efficiency of PM2.5 of the micro-electrostatic filter reaches 95 percent. Not only has no consumable, but also can effectively sterilize, and can not generate ozone. The micro-static filter screen is mainly composed of an electric sheet and a special insulating material, is light in weight relative to the flat plate static of metal, and is convenient to install, maintain and clean. The micro-electrostatic filter can be repeatedly washed without replacement, and is interlocked with the air conditioner fan to start and stop.
The total heat exchanger is arranged in the suspended ceiling of the living room. The fresh air inlet is led from a rainproof shutter on the outer wall, a primary filter and a middle-effect filter are additionally arranged on a fresh air pipeline in the suspended ceiling to block viruses, filter PM2.5 particles and the like; because the total heat exchanger can send and exhaust heat exchange in the equipment, the clean air and the polluted air can not meet, and because the indoor room air outlet is arranged in each equipment platform, the influence on the upper and lower floors and the adjacent partition wall can be generated, and the air outlet is closed. Only set up bathroom and exhaust can satisfy indoor ventilation requirement, the specific requirement is as follows: the toilet is provided with a mechanical air exhaust device, and the ventilation times per hour are not less than 10 times; the outdoor exhaust outlet is higher than the roof high-altitude emission, and the purification treatment is carried out before the emission.
The air exhauster for toilet is set on the roof, and the combined air blower box with integrated high-efficiency filter is used, so that the filter can be replaced by the property on the roof regularly. The fan is a variable frequency motor, and runs at low air volume at ordinary times, the exhaust volume is smaller than the fresh air volume, and the indoor positive pressure is ensured; through the variable frequency control cabinet, the frequency of the fan is increased rapidly, the air discharge quantity is increased, the indoor air discharge quantity is far greater than the fresh air quantity, the indoor negative pressure is ensured, the air flow flows from the outdoor clean area to the indoor pollution area, and the polluted air is prevented from overflowing. The possibility of intercommunication of air in each building is radically eliminated. An electric sealing valve is arranged at the inlet of the fan and is interlocked with the fan to open and close.
Scientifically and effectively cuts off the transmission path and protects the susceptible population. Newly-built residential building, arranging a micro-static purifier at an air return inlet of an air conditioner indoor unit; a primary and a middle-effect filters are arranged at the fresh air inlet; the high-efficiency filter is arranged at the exhaust outlet to exhaust the toilet at high altitude; the product is used for a certain improvement and innovation of the household multi-connected air conditioner and the ventilation system, and can quickly change the air quantity in sudden infectious diseases, adjust the indoor environment into negative pressure and effectively prevent cross infection.
The foregoing is merely exemplary embodiments of the present invention and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and scope of the present invention are included in the protection scope of the present invention.
