Abstract
A cabin condenser for a heating, ventilation, and air conditioning (HVAC) system for a battery electric vehicle (BEV). The cabin condenser includes a first cabin condenser portion and a second cabin condenser portion. A regulator is configured to control flow of refrigerant from the first cabin condenser portion to the second cabin condenser portion.
Claims18
A cabin condenser for a heating, ventilation, and air conditioning (HVAC) system for a battery electric vehicle (BEV), the cabin condenser comprising:
- a first cabin condenser portion;
- a second cabin condenser portion;
- a regulator configured to control flow of refrigerant from the first cabin condenser portion to the second cabin condenser portion, the regulator defines a first chamber through which refrigerant flows from the first cabin condenser portion into the second cabin condenser portion, and the regulator defines a second chamber through which refrigerant flows from the second cabin condenser portion, a divider separates the first chamber from the second chamber so that the first chamber is fluidly independent of the second chamber;
- and
- an airflow divider between the first cabin condenser portion and the second cabin condenser portion to separate airflow through the first cabin condenser portion from airflow through the second cabin condenser portion;
- wherein airflow through the first cabin condenser portion flows to a passenger cabin of the BEV, and airflow through the second cabin condenser portion flows to an exterior of the BEV.

A heating, ventilation, and air conditioning (HVAC) system for a battery electric vehicle (BEV) comprising:
- a chiller configured to cool a battery of the BEV;
- a cabin condenser in fluid communication with the chiller to receive refrigerant warmed by the chiller, the cabin condenser including a first cabin condenser portion, and a second cabin condenser portion;
- and
- a regulator configured to control flow of refrigerant from the first cabin condenser portion to the second cabin condenser portion, the regulator defines a first chamber through which refrigerant flows from the first cabin condenser portion into the second cabin condenser portion, and the regulator defines a second chamber through which refrigerant flows from the second cabin condenser portion, a divider separates the first chamber from the second chamber so that the first chamber is fluidly independent of the second chamber;
- wherein the first cabin condenser portion is in a first airflow duct portion that directs airflow to a passenger cabin of the BEV, and the second cabin condenser portion is in a second airflow duct portion that directs airflow to an exterior of the BEV such that airflow through the first cabin condenser portion is independent of airflow through the second cabin condenser portion.
