Material) composition, it may be provided at the inside of unit.After the completion of consumptive material use, regularly replaced by maintenance staff.
Embodiment 2
Air quality is poor indoors for traditional combination sideboard or straight-expansion type air conditioner unit, in the case where cleanliness difference, increases
Fresh air volume does not consider that haze air leads to the situation of New atmosphere quality difference.The cleanliness to fresh air and return air temperature is added in the present invention
Comprehensively consider, introduce the minimum comfort level of human body cleanliness.The concepts adjustment unit such as comprehensive fresh air, return air, human comfort
Operating status.And purification device (consumptive materials of the solid particulate matters such as adsorbable filtering PM2.5, refrigerant) are replaced in cleaning automatically.Because of water
There is risk of the leakage refrigerant to subway station in cold direct refrigeration-type air-conditioning, it is therefore desirable to consider refrigerant such as R22/R134a etc. pairs
The influence of air purity.
Cleanliness is defined as the virtual parameter that PM2.5, carbon dioxide, refrigerant isoconcentration measurement value sensor are fitted,
Formula is as follows: air purity Q=a × P1+b×P2+c×P3。
P1- PM2.5 concentration sensor measured value；
P2- CO2 concentration sensor measured value；
P3- refrigerant concentration sensor measured value；
A-PM2.5 concentration cleanliness correction factor；
B-CO2 concentration cleanliness correction factor；
C-refrigerant concentration cleanliness correction factor；
Q1Air purity calculated value in-subway station；
Q2Air purity calculated value outside-subway station；
Q3The passenger (such as passenger more than 95%) of-preset ratio bears cleanliness minimum.
