Patent number: 5033537Abstract: There is disclosed an air conditioning unit for location in the wall of a room and which comprises a heat exchanger, an external supply fan operable to blow air into the room through the heat exchanger and an extract fan operable to draw air out of the room through the heat exchanger, in which the heat exchanger comprises a stack of thin flexible plates which are spaced apart from each other so as to define between opposed faces of adjacent plates extract air flow paths and supply air flow paths through the heat exchanger, with the spacing apart of the faces defining the extract air flow paths being greater than the spacing apart of the faces defining the supply air flow paths whereby the depth of the extract air flow paths initially is greater than the depth of the supply air flow paths, but during operation any tendency for the flexible plates to deform under differential pressure action results in the depths of the extract air flow paths and supply air flow paths being substantially equalized, which providType: GrantFiled: October 13, 1989Date of Patent: July 23, 1991Assignee: Advance Design & Manufacture LimitedInventors: Howard S. Atkin, Christopher J. Palmer
