A thermal management system includes a closed-circuit refrigeration system that includes a closed-circuit refrigerant fluid path configured to store a refrigerant fluid; and an absorber/desorber including a bidirectional port coupled to the closed-circuit refrigerant fluid path to regulate an amount of refrigerant vapor at a compressor inlet of the closed-circuit refrigeration system. The absorber/desorber is configured to store an ionic liquid that is configured to absorb or desorb at least a portion of the refrigerant vapor based on a mode of operation of the absorber/desorber.

System and methods for OCR sensing with a suction-line accumulator are provided. The accumulator may include a sensor configured to detect the level of oil. The accumulator may further include a valve which opens when oil is at a high-level and closes when oil is at a low-level. The accumulator may measure a mass flow rate of oil in the vapor compression cycle system based on an amount of time taken to fill a portion of the accumulator. The accumulator may further determine an oil circulation ratio based on the measured time taken to fill the portion of the accumulator. The smart accumulator may output the oil circulation ratio.

Provided is an accumulator that can effectively suppress impact noise associated with a bumping phenomenon when a compressor is operating, without an increase in the complexity, cost, or size of the accumulator. An inlet port 15 is disposed in the lower portion of a tank 10, and a gas-liquid separation accelerating plate 22 is disposed above inlet port 15 inside the tank 10 so that the gas-liquid separation accelerating plate 22 is opposite the inlet port 15.

The present solution provides a cyclone for separation of gas-liquid mixtures, particularly suitable for a refrigerant accumulator or an accumulator with an internal heat exchanger in a vehicle air conditioning system using carbon dioxide as refrigerant, including an inlet of the gas-liquid mixture and a body of the cyclone with an inlet chamber, an outlet chamber, and at least one stationary vane in the form of a helix to ensure rotation of the mixture in the cyclone outlet chamber, where the gas-liquid mixture inlet is arranged substantially coaxially with the axis of the cyclone and opens directly into the inlet chamber of the cyclone body. The solution further provides a refrigerant accumulator and an accumulator with an integrated internal heat exchanger which includes the cyclone according to the invention.

Provided are a gas-liquid separator and an air conditioning system of a vehicle. The gas-liquid separator includes: a housing having a liquid inlet, a liquid outlet, an air inlet and an air outlet; a middle cylinder arranged in the housing and provided with a separation recess, a first flow channel formed between an inner surface of the housing and an outer surface of the middle cylinder is configured to communicate the air inlet with the separation recess; an inner cylinder that is at least partially accommodated in the middle cylinder and forms a second flow channel together with an inner surface of the middle cylinder, the second flow channel being configured to communicate the separation recess with the air outlet; a third flow channel formed in the inner cylinder is configured to communicate the liquid inlet with the liquid outlet.

Provided is an accumulator that has a superior assembly property and that enables to ensure a function of a refrigeration cycle even when vibration is applied. The accumulator includes a body, a pipe arranged on an inner side of the body eccentrically with respect to the body, a retaining member arranged between the pipe and the body, and a bag configured to accommodate a desiccant, wherein the bag is retained by being in contact with the body and the retaining member at a position where a distance between an inner circumference surface of the body and an outer circumference surface of the pipe is greatest.

Provided is an accumulator capable of effectively suppressing a bumping phenomenon and the following impact noise during the starting of a compressor without making the structure of the accumulator complicated or increasing the cost and the size thereof, and so having cost-effectiveness. An accumulator includes: a tank 10 having an inflow port 15 and an outflow port 16; and a double-pipe structured outflow pipe 30 including an inner pipe 31 joined to the outflow port 16 and hanging inside of the tank 10, and an outer pipe 32 disposed outside of the inner pipe 31. A cloth-like member such as felt or a foam material 60 is wound around or externally inserted to the outer pipe 32.
