FILTER BOX AND AIR CONDITIONING SYSTEM USING THE SAME

PROBLEM TO BE SOLVED: To provide a filter box and an air conditioning system using the filter box facilitating the maintenance of a filter and simplifying construction. SOLUTION: The air conditioning system 10 has a total enthalpy heat exchange unit 12 arranged in a ceiling internal space 11a of a building 11; the filter box 13 arranged at the back of a ceiling 11c of a hall 11h; and air supply ports 14 formed at in the ceilings 1c, 2c of living rooms 1r, 2r. A branch box 15b is disposed between the first floor 1F and the second floor 2F, and an outside air intake port 16 and an exhaust port 17 are formed at parts facing the outside of the building 11. An outside air duct 19b and an exhaust duct 21a are piped between the filter box 13 and the total enthalpy heat exchange unit 12. An outside duct 19a is piped between the filter box 13 and the outside air intake port 16. An exhaust duct 21b is piped between the total enthalpy heat exchange unit 12 and the exhaust port 17.
