Unitary matrix, valve and fan housing for energy recovery

An energy ventilation system for an enclosure, said system including:

• supply and exhaust ducting extending within said enclosure;
• a matrix box consisting of an outer open ended housing and internal intersecting and longitudinally-extending partition walls whereby the housing is partitioned into four quadrants, each defining an elongated channel within said outer housing;
• air supply fan means mounted in a first of said channels producing air flow therethrough;
• exhaust fan means mounted in a second of said channels producing air flow therethrough;
• a heat storing matrix located in each of a third and fourth of said channels;
• valve means alternately positionable to establish an air flow path through each of said first and second channels and opposite ones of said third or fourth channels, said valve means including a unitary moveable vane positioned at one end of said matrix box housing contiguous with said partitions and moveable between a first position wherein the vane is in alignment with one of said partition walls and a second position wherein the vane is in alignment with the other of said partition walls to establish air flow paths through said first, second, third and fourth channels;
• means for cyclically moving said valve means between said alternate positions;
• transition housing means disposed at the other end of said matrix box housing for connecting each of said third and fourth channels to a fresh air source;
• means connecting said first channel to said supply ducting;
• and
• means connecting said second channel to said exhaust ducting;
• whereby said cyclical operation of said valve means causes alternate exhaust and supply air flow through each of said third and fourth channels and over each of said heat storing matrixes and whereby heat may be exchanged between said exhaust air flow and said supply air flow.
