AI Technical Summary

Technical Problem

Existing motor vehicle cooling systems face limitations in cooling additional compartments like glove compartments and require complex refrigerant circuits with multiple expansion valves, leading to reduced cooling capacity and operational complexity.

Method used

A refrigerant circuit design that routes refrigerant from the evaporator through a container for transported goods, using a single expansion device to cool the container directly, avoiding split refrigerant flows and simplifying the system.

Benefits of technology

Achieves efficient and easy operation with temperatures below 8°C in the container, allowing intensive cooling of transported goods without reducing passenger compartment cooling capacity, while minimizing system complexity.

Abstract

The invention relates to a cooling arrangement (10) for a motor vehicle, comprising a refrigerant circuit (14) which includes a compressor (16) and at least one evaporator (18). In cooling mode, refrigerant can be supplied to the at least one evaporator (18), which can be expanded by means of at least one expansion device (30) of the refrigerant circuit (14). The cooling arrangement (10) comprises a container (34) with a receiving space (36) for receiving transported goods, wherein, in cooling mode, the receiving space (36) of the container (34) can be cooled. A refrigerant line (40) of the refrigerant circuit (14), through which refrigerant coming from the at least one evaporator (18) can be supplied to a suction side (42) of the compressor (16), passes through the container (34). Furthermore, the invention relates to a motor vehicle with the cooling arrangement (10) and a method for operating the cooling arrangement (10).
