Benefits of technology

[0017] There are a number of advantages of the present invention. First, the housing can mount directly to the return air duct of a heating or cooling system. Also, the housing requires only two separate duct pipes to be installed instead of four, saving installation time and cost. Installation of the energy recovery ventilator of the present invention is also very flexible because it can be installed in a number of different orientations and locations on the return air duct of a heating or cooling system, or on a wall, ceiling, or other mounting location as a stand-alone unit.
[0018] In addition, the hinged bar mountin

Problems solved by technology

The prior art energy recovery ventilator units are costly and cumbersome to install in that they require the installation of four separate duct pipes to carry each air stream to or from the fresh air or stale air spaces.
Further, it is difficult f

Abstract

An energy recovery ventilator wherein two of the air flow openings are in direct communication with either the fresh air space or the stale air space. The energy recovery ventilator has a housing with at least a first face panel holding a heat exchange device. The housing includes two air flow openings in the first face panel of the housing, in direct communication with the stale air space, and two other air flow openings in the housing in communication with the fresh air space through duct pipes. Alternatively, the first two air flow openings are in direct communication with the fresh air space, and the other two air flow openings are in communication with the stale air space through duct pipes. The energy recovery ventilator also includes a hinged bar mounting system and a control system. The features of the present invention facilitate ease of installation.

Description

BACKGROUND OF THE INVENTION [0001] The present invention relates generally to air-to-air heat exchangers, otherwise known as energy recovery ventilators, and more particularly to an energy recovery ventilator with features facilitating ease of installation. The design of the present invention provides a more efficient and more cost effective method for installing an energy recovery ventilator. [0002] An energy recovery ventilator is generally used to exhaust stale air from a stale air space to a fresh air space and bring in fresh air from the fresh air space to the stale air space while exchanging heat or cool energy, thereby reducing heating or cooling requirements associated with fresh air introduction. Energy recovery ventilators are often used in connection with a heating or cooling system, wherein the stale air space is sometimes a return air duct of the heating or cooling system, and the fresh air space is generally the outdoors. [0003] When in use with a heating or cooling sy...
