US 5,236,476 A · Air purification system for enclosed arenas

Abstract

The invention relates to an air circulation and filtration system for use with an indoor ice-skating arena. The air circulation and filtration system consists of intake and return air panels which replace and simulate in substantially all respects the boundary "boards" commonly used in indoor ice-skating facilities. The circulation and filtration system remains designed to remove undesirable gases such as carbon monoxide, carbon dioxide, nitrogen dioxide, and exhaust gases emanating from ice resurfacing machinery, from the ice-skating areas used by skaters. The return air panels contain a plurality of angularly offset air passage apertures which direct an air circulation course within an indoor ice-skating arena. The angularly offset air passage apertures promote a circular air course proximal to the ice-skating surface. The location of the intake air panels also promotes a circular air flow course. The filtration system significantly reduces the volume of undesirable gases exposed to skaters, thereby significantly improving the comfort of persons using indoor ice-skating facilities.

Dependent claims

A circulation and filtration system for an indoor ice-skating arena having a plurality of board sections surrounding an ice surface having a center ice area and end ice areas comprising:

(a) a first board section positioned adjacent said center ice area of said ice-skating arena, said first board section comprising:
(i) a frame defining the periphery of said first board section;
(ii) a front surface engaged to said frame, said front surface covering said frame, said front surface having a plurality of openings therethrough comprising a first air panel;
(iii) a rear surface engaged to said frame opposite to said front surface, wherein said rear surface covers said frame;
(iv) at least one support defining an air passage between said front surface and said rear surface, wherein said support traverses said frame;
and
(v) at least one opening through said rear surface;
(b) a second air panel in a second board section;
(c) a duct means engaged to said opening through said rear surface, said duct mans confining an air flow course between said first air panel and said second air panel;
(d) an air filter connected in air flow relation to said duct means;
(e) an air fan connected in air flow relation to said duct means;
(f) at least one gas sensor for detection of undesirable gases selected from the group consisting of carbon monoxide, carbon dioxide, and nitrogen dioxide, said sensor affixed to one of said plurality of board sections inside said ice-skating arena proximal to said ice surface;
and
(g) a condenser connected in air flow relation to said duct mans.
