    摘要： Disclosed are methods of recharging an operating system of the type containing a less than full charge of existing working fluid with a recharging fluid that is different than said existing fluid, the method comprising: (a) identifying at least one readily measured physical property of fluids comprising combinations of the existing working fluid and the recharging working fluid wherein said physical property reliably correlates to target component concentrations of the working fluid after recharge; (b) providing a system which contains less than a full charge of the existing working fluid; (c) adding to the existing working fluid a recharging fluid having at least one property superior to that property of the existing working fluid; (d) at least after said adding step (c), measuring said readily measured physical property of the operating fluid in the system; and (e) based on said measuring step, repeating or not said steps (c) and (d) and/or adjusting at least one system operating parameter.

    摘要： Heat transfer compositions and methods wherein the compositions have a burning velocity (BV) of less than about 10 and a global warming potential (GWP) of less than about 400 comprising: (a) from about 0 to about 50% by weight of HFC-32; (b) from about 50% to about 90% by weight of a compound selected from unsaturated -CF3 terminated propenes, unsaturated -GF3 terminated butenes, and combinations of these; and (c) from about 0 to about 25% by weight of a compound selected from NFO~1243zf, HFC-152a, and combinations of these, provided that the combination of components (a) and (c) together comprise at least about 10% by weight of the composition, and further provided that the amount of each of the components (a), (b) and (c) is selected to ensure that the 8V of the composition is less than about 10 and the GWP of the composition is less than about 400.

    摘要： Disclosed are refrigeration systems of the type having a heat source to be cooled and a heat sink into which heat can be rejected, said system preferably having a capacity of from about 2 to about 30 tons and comprising: (a) a heat transfer composition comprising a refrigerant comprising at least about 80% by weight of trans1-chloro-3,3,3-trifluoropropene (HCFO-1233zd(E)) or at least about 80% by weight of trans1,3,3,3-tetrafluoropropene (HFO-1234ze(E)); (b) a centrifugal compressor having: (i) a refrigerant suction for receiving a relatively low-pressure refrigerant vapor at a pressure of from about 40 to about 350 kPa and (ii) a discharge for discharging a relatively high pressure refrigerant vapor at a pressure wherein the discharge:suction pressure ratio is at least about 2:1; (c) a condenser operating at temperature in the range of from about 10° C. to about 60° C.; (d) and expander for producing relatively cold low pressure refrigerant liquid; (e) a high efficiency evaporator, preferably a flooded evaporator, fluidly connected to said expander for receiving said low pressure refrigerant liquid from said expander and evaporating said low pressure refrigerant liquid by absorbing heat from said source to be cooled to produce a relatively low pressure refrigerant vapor at a pressure of from about 40 to about 350 kPa, said refrigerant vapor exiting from said evaporator preferably having no substantial superheat; (f) at least one heat exchanger fluidly connected between said evaporator and said refrigerant suction of said compressor.
