Title:
AIR FILTER UNIT AND AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2020/004504
Kind Code:
A1
Abstract:
A fan filter unit is provided in which, when operating such that the blowing efficiency η of a blower is 0.75, the power consumption efficiency, given by the formula below, is less than or equal to 600 kWh/(m2*year). Q in the equation below is the rated flow rate (m3/s) of the air filter unit, ΔP is the pressure loss (Pa) of the air filter unit for air passing through the air filter unit at the rated flow rate of said unit, and S is the open area (m2) of the air filter unit. Formula: Power consumption efficiency kWh/(m2*yr) = {(Q×ΔP)/(η×1000)}×(24×365)/S.This air conditioner is suitable to reducing power consumption even when the air filter unit is large in size and has a high collection capacity.
