Abstract
Official abstract text for this publication.
A heating, ventilation, and/or air conditioning (HVAC) system includes: a furnace having a furnace heat exchanger; and an indoor HVAC unit having a refrigerant heat exchanger. At least one of a component of the furnace and a component of the indoor HVAC unit are selectively removable from an airflow path of the HVAC system.
First claim
Opening claim text (preview).
What is claimed is: 1. A heating, ventilation, and/or air conditioning (HVAC) system, comprising: a furnace comprising a furnace heat exchanger; and an indoor HVAC unit comprising a refrigerant heat exchanger and an indoor fan, wherein the indoor fan is configured to generate an airflow through each of the furnace and the indoor unit; wherein at least one of the furnace and the indoor HVAC unit comprises a selectively adjustable barrier configured to selectively allow at least a portion of the airflow to bypass at least one of the furnace heat exchanger and the refrigerant heat exchanger. 2. The HVAC system of claim 1 , wherein the selectively adjustable barrier is configured to selectively allow at least a portion of the airflow to bypass the furnace heat exchanger. 3. The HVAC system of claim 1 , wherein the selectively adjustable barrier is configured to selectively allow at least a portion of the airflow to bypass the refrigerant heat exchanger. 4. The HVAC system of claim 1 , wherein the furnace and the indoor HVAC unit are configured to be disposed in different airflow paths. 5. The HVAC system of claim 1 , further comprising: a bypass duct comprising an airflow path that includes neither the furnace nor the indoor HVAC unit. 6. The HVAC system of claim 1 , wherein the selectively adjustable barrier of the furnace comprises an operational position in which substantially all of the airflow passes through the furnace heat exchanger, and the selectively adjustable barrier of the furnace comprises a passive position in which at least a portion of the airflow bypasses the furnace heat exchanger. 7. The HVAC system of claim 1 , wherein the selectively adjustable barrier of the indoor HVAC unit comprises an operational position in which substantially all of the airflow passes through the refrigerant heat exchanger, and the selectively adjustable barrier of the indoor HVAC unit comprises a passive position in which at least a portion of the airflow bypasses the refrigerant heat exchanger.
