An air conditioning system for a vehicle including a vapor compression-type refrigerating cycle and using combustible refrigerant includes a refrigerant recovery vessel in communication with a gas-liquid separator and which of recovers the combustible refrigerant by the communication with the gas-liquid separator, and a valve which controls the communication between the refrigerant recovery vessel and the gas-liquid separator in response to an external signal. When combustible refrigerant is used as refrigerant of a vapor compression-type, refrigerating cycle, leakage of the refrigerant may be reduced, minimized, or eliminated, and the recovery of the refrigerant may be carried out readily and efficiently without requiring significant changes to the system configuration.

An automotive air-conditioning system has a gas-liquid separator, a compressor and a radiator, which are interposed in a first flow channel of a refrigerant which extends within an engine room in the order in the flowing direction of the refrigerant. The system also includes a pressure reducer and an evaporator, which are interposed in a second flow channel of the refrigerant which extends within a vehicle interior in the order in the flowing direction of the refrigerant. The system also has a connecting device disposed near a partition wall that separates the engine room from the vehicle interior. The connecting device circularly connects the first to the second flow channel, and includes a first connecting portion formed at the downstream end of the second flow channel and a second connecting portion that is formed at the inlet of the gas-liquid separator and is connected to the first connecting portion.

An air conditioning system for a vehicle includes an outdoor heat exchanger, an indoor heat exchanger, and an inside heat exchanger. The inside heat exchanger exchanges heat between a refrigerant at a high-pressure and a refrigerant at a low-pressure during a refrigeration cycle. Both the outdoor heat exchanger and the inside heat exchanger include a plurality of tubes, and each of the plurality of tubes has a plurality of holes formed therethrough, which extend parallel to each other in the tubes. A cross-sectional shape of the plurality of tubes in the inside heat exchanger is the same as a cross-sectional shape of the plurality of tubes in the outdoor heat exchanger.
摘要:
A vapor compression refrigerating system having a compressor, a radiator, a first pressure reducing mechanism for reducing a pressure of refrigerant cooled by the radiator, a refrigerant branching means for dividing refrigerant (m) reduced in pressure by the first pressure-reducing mechanism into portions, a second pressure reducing mechanism for reducing a pressure of one portion of refrigerant (m1), and a third pressure reducing mechanism for reducing a pressure of another portion of refrigerant (m2). One portion and pressure reduced refrigerant (m1′) exchanges heat in a cooler with refrigerant present between the first and third pressure reducing mechanisms, and another portion and pressure reduced refrigerant (m2′) is evaporated by an evaporator. The evaporated refrigerant (m2″) and the refrigerant (m1′) having passed through the cooler are mixed by a gas/liquid separator, and the mixed refrigerant is introduced into the compressor. In a vapor compression refrigerating system using carbon dioxide, the degree of refrigerant superheating at a suction side of the compressor may be reduced, and a coefficient of performance of the refrigerating cycle may be increased.

An air conditioning system for a vehicle includes a compressor, a gas cooler, an expansion means, and a cooler. The system also includes an elevated pressure density detector for detecting or estimating one or more physical values having a correlation with a density of an elevated pressure refrigerant in a refrigeration cycle. An elevated pressure density controller controls the density of the elevated pressure refrigerant. This control is achieved at least in part by using at least one of the one or more physical values.
