A refrigerant consisting or consisting essentially of:

Thermal pump refrigerants

Non-ozone depleting and non-flammable refrigerant compositions with GWPs less than 1050 which may replace HFC404A, HFC507 and HFC410A in refrigeration and air-conditioning systems.

Low GWP refrigerant blends

Non ozone depleting and non flammable refrigerant compositions with GWPs between 1,000 and 1600 ITH which may replace R404A and R507 in refrigeration systems.

Non-ozone depleting and low global warming refrigerant blends

A refrigerant composition consisting essentially of a hydrofluorocarbon component consisting of:

Refrigerant

A refrigerant composition consisting essentially of R227ea 3-9% R134a 25-70% R125 3-35% R32 10-35% together with an optional hydrocarbon component; wherein the amounts are by weight and are selected to total 100%.

A refrigerant composition consists essentially of three hydrofluorocarbon components selected from HFC134a, HFC125 and HFC143a and an additive selected from a saturated or unsaturated hydrocarbon or mixture thereof boiling in the range &#x2212;50&#xb0; C. and +40&#xb0; C.

Refrigerant composition

Non ozone depleting and non flammable refrigerant compositions with GWPs less than 2,000 ITH which replace R404A, R507, HCFC22 and CFC502 in refrigeration systems.

Non ozone depleting and low global warming potential refrigerants for low temperature refrigeration

A refrigerant composition consists essentially of a combination of two hydro fluorocarbon components selected from R125 and R143a and an additive selected from a saturated or unsaturated hydrocarbon or mixture thereof boiling in the range &#x2212;50&#xb0; C. and +40&#xb0; C.
