Air Conditioning Device for a Compartment, in Particular for a Railroad Vehicle

摘要

The air conditioning device (10) according to the invention comprises a primary heat pump circuit (12), comprising at least one primary heat exchanger (14) with the air from the compartment, a primary compressor (16), a second primary heat exchanger (18) with the outside air, and a primary expander device (20), and a heat storage reservoir (46), connected to the primary circuit (12), in parallel with said first primary heat exchanger (14) with the air from the compartment. The air conditioning device (10) comprises a secondary heat pump circuit (12′), comprising a first secondary heat exchanger (14′) with the air from the compartment, a secondary compressor (16′), a second secondary heat exchanger (18′) with the air from the outside, and a secondary expander device (20′). The heat storage reservoir (46) is connected to the secondary circuit (12′), in parallel with said first secondary heat exchanger (14′) with the air from the compartment.
