AN AIR-TO-AIR HEAT AND ENERGY RECOVERY VENTILATOR THAT CAN BE CONFIGURED FOR PORTABILITY

ABSTRACT An invention that alleviates the challenges associated with providing energy-efficient ventilation in air-tight buildings at a reasonable cost is presented. The invention is an air-to-air heat and energy recovery ventilator (H/ERV) that can be used to passively heat or cool and/or humidify or dehumidify air depending on the operating condition. Furthermore, the H/ERV may be specially designed and operated as a portable ventilation system. The H/ERV is based on a modular design in which appropriate off-the-shelf parts can be tightly assembled to achieve leak-proof operation. The critical component of the H/ERV is a polymer-based, compact, and efficient quasi-counter-flow shell-and-tube exchanger. The exchanger facilitates the transfer of heat or energy between two separate air streams that are at different temperatures and/or humidity. CA 3066568 2020-01-06
