Open the CIPO recordAbstract From the Canadian patent
The present invention is an air conditioning unit with indoor and outdoor heat exchanger coils and a pair of dual tangential flow blowers. Air flow is induced through the coils at a uniform rate and exhausted through an outlet. A single scroll dividing wall divides the housing of the air conditioner into indoor and outdoor compartments. The air-conditioning unit has a relatively small depth because the blowers are positioned in vertical alignment. The air intake arrangement on the indoor side is an intended recessed portion of the cabinet. A removable louvered cover is positioned in an aperture located in the indented recessed portion for allowing access to the filter.

Why it's free to use
- Filed December 4, 1990 and granted April 26, 1994. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended December 4, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 4, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
