Cascaded refrigeration systems containing: a plurality of refrigeration units, each refrigeration unit containing a first refrigeration circuit, each first refrigeration circuit comprising an evaporator and a heat exchanger; and a second refrigeration circuit; wherein each first circuit heat exchanger is arranged to transfer heat energy between its respective first refrigeration circuit and the second refrigeration circuit.

Refrigeration systems and methods

Disclosed are refrigerants, and heat transfer compositions, heat transfer systems and heat transfer methods containing such refrigerants, wherein the refrigerant comprises at least about 97% by weight of the following three components (a)-(c) and the following fourth component if present:

Refrigerant, heat transfer compositions, methods, and systems

Compositions, methods and systems which comprise or utilize a multi-component mixture comprising: (a) HFC-32; (b) HFC-125; (c) HFO-1234yf and/or HFO-1234ze; (d) HFC-134a. In certain non-limiting aspects, such refrigerants may be used as a replacement for R-404A.

Heat transfer compositions and methods

Compositions, methods and systems which comprise or utilize a multi-component mixture comprising: (a) from about 10% to about 35% by weight of HFC-32; (b) from about 10% to about 35% by weight of HFC-125; (c) from about 20% to about 50% by weight of HFO-1234ze, HFO-1234yf and combinations of these; (d) from about 15% to about 35% by weight of HFC-134a; and optionally (e) up to about 10% by weight of CF3I and up to about 5% by weight of HFCO-1233ze, with the weight percent being based on the total of the components (a)-(e) in the composition.

Provided is a composition comprising (a) at least one halogenated compound selected from the group consisting of C-Chydrofluoroolefin, CFI, and combinations thereof, and (b) an effective stabilizing amount of a sesquiterpene selected from the group consisting of farnesol, farnesene, and mixtures thereof.
