Photocatalytic air conditioning filter module with antiviral performance

A photocatalytic air-conditioning filter module, which is applied to a target space, the photocatalytic air-conditioning filter module comprising:

• a first casing partition wall part having a plurality of first lattice-shaped spaces;
• a second casing partition wall part disposed at a rear end of the first casing partition wall part in a staggered manner, the second casing partition wall part having a plurality of second lattice-shaped spaces;
• a first single photocatalytic ball accommodated in each of the first lattice-shaped spaces;
• a second single photocatalytic ball accommodated in each of the second lattice-shaped spaces;
• a first cover configured to cover a front surface of the first casing partition wall part and prevent the first single photocatalytic ball from separating from the first casing partition wall part;
• and
• a second cover configured to cover a rear surface of the second casing partition wall part and prevent the second single photocatalytic ball from separating from the second casing partition wall part,
• wherein the first single photocatalytic ball has a size to be able to form a first available interval in at least one of a horizontal direction and a vertical direction of each of the first lattice-shaped spaces so that the first single photocatalytic ball moves correspondingly to a flow of air in the first lattice-shaped spaces, and the second single photocatalytic ball has a size to be able to form a second available interval in at least one of a horizontal direction and a vertical direction of each of the second lattice-shaped spaces so that the second single photocatalytic ball moves correspondingly to a flow of air in the second lattice-shaped spaces,
• wherein the first available interval and the second available interval are configured such that the first single photocatalytic ball and the second single photocatalytic ball partially overlap each other when viewed from a front side or a rear side even though the first single photocatalytic ball is maximally spaced apart from an adjacent second single photocatalytic ball,
• wherein the first cover includes ball separation prevention members, each extending across a middle portion of each of the first lattice-shaped spaces, the second cover includes ball separation prevention members, each extending across a middle portion of each of the second lattice-shaped spaces, and
• wherein the second casing partition wall part has a hole defined in a lateral side of the second lattice-shaped spaces, and the hole is smaller than the second single photocatalytic ball as to allow air to communicate between adjacent second lattice-shaped spaces to reduce a differential pressure while preventing the second single photocatalytic ball from passing therethrough.
