Abstract

An improved high performance ventilation system for application with relatively small temperature-controlled structures for recovering a high percentage of sensible and latent thermal energy from the exhausted air for return via the fresh air stream. Two matrices of thermally absorbent, expanded honeycomb material are alternately interconnected with fan driven supply and exhaust paths via a valve device to store energy in one matrix while retrieving it from the other. The matrices, valve and fans are contained within a single compact highly portable housing which can be installed on the floor, beneath the ceiling and on the roof of the intended structure. Constant air flow direction is maintained in the ventilated area. The valve may be thermostat controlled. The housing is manufactured with a modular design allowing final on-site assembly in a number of varying configurations.
