Description
Technical field:
The present invention relates to indoor air purification product and technical field of measurement and test, refer in particular to a kind of and suitable wall-hanging air conditioner air cleaning attachment device of being combined with the wall hanging air-conditioning, to make present common wall-hanging air conditioner increase air-cleaning function, in addition, the invention allows for the corresponding detection method that a kind of performance to this attachment device, secure context are formulated.
Background technology:
Air-conditioning has become the basic household electrical appliance configuration of domestic households, and present recoverable amount is about 300,000,000, and with every year nearly 4,000 ten thousand quantity increasing, wherein 80% is 1～1.5 wall-hanging air conditioner.
Problems such as the formaldehyde that indoor decoration pollution brings, VOC, its harmfulness more and more is familiar with, air-conditioning between the operating period door and window be in closed condition, room air is few with extraneous circulation, the pollutant that finishing pollution distributes is difficult for diffusion, causes concentration to exceed the safe concentration of health risk easily.Investigation shows, indoor formaldehyde concentration exceeds standard and mostly occurs during 2:00 AM to 5, closes the doors and windows the time of sleeping soundly just.
Atmosphere ash haze pollutes the PM2.5 particle that causes and the harm that brings, and is proved.According to the requirement of civil buildings design specification, room air per hour on average should exchange once with outdoor air.Even if close the doors and windows in the bedroom at night, to draw the curtain together, rate of ventilation also reaches 0.4～0.6 time/hour, and exchange process will be introduced outdoor pollutant component.Simulation test shows, under the condition of closing the doors and windows, the indoor PM2.5 concentration of civil buildings is about outdoor 0.6～08 times, for example: when outdoor PM2.5 concentration is 300ug/m3, the indoor 200ug/m3 that is about has far exceeded the basic standard of the annual average 35ug/m3 of regulation.When air-conditioning work during in refrigerating state, temperature reduces contraction of gas, needs outdoor gas make-up enter the balance that keep-ups pressure, and this will directly introduce the contaminated air of the outdoor PM2.5 of containing.
Based on the above, air cleaning is being applied universal, and a present air purifier comprises four parts substantially:
1, shell.
2, the automatically controlled part of control air quantity and function.
3, mobile blower fan, the air channel of driving gas.
4, core component: air cleaning filter part.
See shown in Figure 1ly, this is present a common wall-hanging air conditioner structural representation, and shown in figure, this wall-hanging air conditioner 6 comprises: housing 60, in air inlet 61 set screen pack 62, heat exchanger 63, drive blower fan 64, control circuit 66 that air flow.Air-flow, through screen pack 62 and by after heat exchanger 63 coolings, is blown out by air outlet 65 by air inlet 61 inlet ports.With respect to general air purifier, this wall-hanging air conditioner has possessed first three part of air purifier, if can increase an air purification filter part, it also can become an air purifier.
