Abstract

An energy recovery system includes a heating or cooling system and an energy recovery ventilator operably connected to a component of the heating or cooling system. The energy recovery ventilator includes a supply port extending into the component to provide a supply of fresh airflow from the energy recovery ventilator to the component for use by the component. A return port extends into the component configured to receive a flow of stale air from the component while minimizing ingestion of the fresh air flow from the component into the return port. A method of operating an energy recovery system includes flowing a flow of fresh air from an energy recovery ventilator through a supply port into a component of a heating or cooling system. Stale air is flowed from the component through a return port into the energy recovery ventilator.

First claim

The invention claimed is:

1. An energy recovery system comprising:
a heating system; and
an energy recovery ventilator configured for thermal energy exchange between a supply of fresh airflow and a flow of stale air, the energy recovery ventilator operably connected to a circulation air blower compartment of the heating system, the energy recovery ventilator connected to the circulation air blower compartment via:
a supply port extending from a housing of the energy recovery ventilator into the circulation blower compartment to provide the supply of fresh airflow from the energy recovery ventilator to the circulation blower compartment of the heating system for use by the circulation blower compartment; and
a return port extending from the housing of the energy recovery ventilator into the circulation blower compartment, the return port configured to receive the flow of stale air from the circulation blower compartment while minimizing ingestion of the fresh air flow from the circulation blower compartment into the return port;
wherein the return port disposed at a side wall of the housing includes a shield at least partially blocking the fresh air flow from entering the return port, the shield having a triangular cross-section in a plane parallel to the side wall of the housing of the energy recovery ventilator.

2. The energy recovery system of claim 1 , wherein the return port draws the flow of stale air from a lower perimeter of the circulation blower compartment.

3. The energy recovery system of claim 2 , wherein the return port includes a shield with an opening to direct the flow of stale air toward the return port, while shielding the return port from reingestion of the fresh airflow.

4. The energy recovery system of claim 1 , wherein the component is a return air duct of the heating or cooling system.

5. The energy recovery system of claim 4 , wherein the return port is located in the return air duct upstream of the supply port relative to a flow direction through the return air duct.

6. The energy recovery system of claim 1 , wherein the energy recovery ventilator housing is coupled directly to the circulation air blower compartment.
