THERMAL MANAGEMENT SYSTEM FOR VEHICLE - A simplified explanation of the abstract

This abstract first appeared for US patent application 17842604 titled 'THERMAL MANAGEMENT SYSTEM FOR VEHICLE

Simplified Explanation

The abstract describes a thermal management system for a vehicle that includes a base circuit with a compressor, condenser, expansion valve, and evaporator, where a refrigerant is circulated. It also includes a recirculation circuit that branches from the compressor's discharge portion and joins to the compressor's inlet portion, allowing the discharged refrigerant to be recirculated back to the compressor. An adjusting valve is positioned at either the discharge portion or the inlet portion of the recirculation circuit to adjust the flow rate of the refrigerant.

• The thermal management system is designed for vehicles.
• It includes a base circuit with a compressor, condenser, expansion valve, and evaporator.
• A refrigerant is circulated in the base circuit.
• A recirculation circuit branches from the compressor's discharge portion and joins to the compressor's inlet portion.
• The recirculation circuit allows the discharged refrigerant to be recirculated back to the compressor.
• An adjusting valve is positioned at either the discharge portion or the inlet portion of the recirculation circuit.
• The adjusting valve is used to adjust the flow rate of the refrigerant in the recirculation circuit.

Potential Applications

• Electric vehicles
• Hybrid vehicles

Problems Solved

• Efficient thermal management in vehicles
• Recirculation of refrigerant to improve system performance

Benefits

• Improved energy efficiency
• Enhanced cooling performance
• Reduced environmental impact

Original Abstract Submitted

A thermal management system for a vehicle includes a base circuit in which a compressor, a condenser, an expansion valve, and an evaporator are provided in order and in which a refrigerant is circulated, a recirculation circuit branched from a discharge portion of the compressor in the base circuit and joined to an inlet portion of the compressor so that the refrigerant discharged from the compressor is recirculated to an inlet of the compressor, and an adjusting valve positioned at the discharge portion where the recirculation circuit is branched from the base circuit or positioned at the inlet portion where the recirculation circuit is joined to the base circuit, the adjusting valve configured to adjust a flow rate of the refrigerant that flows to the recirculation circuit.
