Abstract: Methods, systems and apparatuses are described that are directed to on-site recovery and/or repurposing of refrigerant, where an original refrigerant is converted into a refrigerant different from the original refrigerant. The refrigerant different from the original refrigerant can have relatively lower global warming potential (GWP) than the original refrigerant. The recovery and/or repurposing can be implemented for example in a refrigeration circuit, such as for example in general cooling and/or heating applications, which may be embodied in a heating, venting, and air conditioning (HVAC) system and/or unit, in a transport refrigeration system and/or unit, as well as in commercial, residential and/or industrial cooling and/or heating applications.

Abstract: Even if, in decompressing a refrigerant by an expansion mechanism, the temperature of the refrigerant cannot be sufficiently reduced, in order to increase the evaporation capacity of a use-side heat exchanger, a main expansion mechanism including an expansion element of a rotary or scroll type that causes power to be produced by decompressing a main refrigerant is provided at a main refrigerant circuit in which the main refrigerant circulates. Further, a sub-refrigerant circuit that differs from the main refrigerant circuit and in which a sub-refrigerant circulates is provided. A sub-use-side heat exchanger that is provided at the sub-refrigerant circuit and that functions as an evaporator of the sub-refrigerant is caused to function as a heat exchanger that cools the main refrigerant that flows between the main expansion mechanism and a main use-side heat exchanger.

Abstract: A heat pump includes a refrigerant loop. The refrigerant loop includes a compressor, a first condenser, a vapor generator having a first region and a second region, a first expansion valve, a second expansion valve, and a first evaporator. A branching point is positioned between the first condenser and the vapor generator. The branching point diverts a portion of a first heat exchange fluid circulating through the refrigerant loop to the vapor generator. The first expansion valve is positioned between the branching point and the vapor generator. An outlet vapor generator is coupled to a mid-pressure inlet port of the compressor.

Abstract: A refrigeration cycle apparatus includes a refrigeration cycle, an adsorption section, and a first bypass flow path. The refrigeration cycle includes a compressor, a radiator, an expansion mechanism, and an evaporator, and uses a non-azeotropic refrigerant mixture including a first refrigerant and a second refrigerant. The adsorption section includes an adsorbent and stores the first refrigerant adsorbed by the adsorbent. The adsorbent adsorbs the first refrigerant, and does not adsorb the second refrigerant or the adsorption performance thereof for the second refrigerant is lower than the adsorption performance thereof for the first refrigerant. The first bypass flow path connects a first end which is a high-pressure part of the refrigeration cycle and a second end which is a low-pressure part of the refrigeration cycle. The adsorption section and a valve are disposed in the first bypass flow path.

Abstract: A refrigerant and oil treatment composition for introduction into a vapor-compression system such as a refrigerator, heat pump, freezer, air conditioner, thermal control device, and refrigerant recovery apparatus has a composition alcohol and a drying agent. The drying agent is 2,2-dimethoxypropane which can react with moisture in the system to form an alcohol as a reaction product. The alcohol reaction product along with the composition alcohol separates any acid in the system from oil, refrigerant and hard surfaces of the system to form an acid-containing solvent composition. The quantity of the composition introduced into the system is based on the adsorption capacity of the filter-drier.

Abstract: A climate-control system can be used to heat or cool a space. The climate-control system may include first and second vessels between which refrigerant and co-fluid may be circulated. The refrigerant may be absorbed into the co-fluid within the first vessel at a first rate. The refrigerant may desorb from the co-fluid within the second vessel at a second rate. Ultrasonic energy may be used to adjust the second rate to substantially match the first rate.
