DEVICE FOR AN AIR CONDITIONING SYSTEM OF A MOTOR VEHICLE AND METHOD FOR OPERATING THE DEVICE
First Claim
1. A device for a climate control system of a motor vehicle, comprising:
- a refrigeration circuit with a compressor for two-stage compression of a refrigerant and injection of the refrigerant at an intermediate pressure level;
at least one heat exchanger operated as a condenser/gas cooler;
a first internal heat exchanger;
at least one first heat exchanger operated as an evaporator arranged upstream from a first expansion element in a flow direction of the refrigerant; and
a first flow path and a second flow path, each of the first flow path and the second flow path extending from a branching point to the compressor, wherein the refrigeration circuit is formed with a second internal heat exchanger, the first internal heat exchanger arranged at least with a low pressure side inside the first flow path, and the second internal heat exchanger arranged at least with an intermediate pressure side inside the second flow path.

Abstract
Device for a climate control system of a motor vehicle. The device includes a refrigeration circuit with a compressor for the two-stage compression of the refrigerant and injection of refrigerant at an intermediate pressure level, at least one heat exchanger operated as a condenser/gas cooler, a first internal heat exchanger, at least a first heat exchanger operated as an evaporator, which is situated upstream from a first expansion element in the flow direction of the refrigerant, as well as a first flow path and a second flow path, each of which extends from a branching point to the compressor. The refrigeration circuit is designed with a second internal heat exchanger. The first internal heat exchanger is arranged at least with a low-pressure side inside the first flow path and the second internal heat exchanger is arranged at least with an intermediate pressure side inside the second flow path.
