发明名称 Apparatus methods and compositions for placing additive fluids into a refrigerant circuit
摘要 A supply canister is partially filled with a refrigerant circuit additive fluid which is partially evacuated, said refrigerant circuit additive fluid is comprised of a combination of a binding azeotrope of methanol and cyclohexanone with a drying agent, a metal sealant and a rubber rejuvinating compound in a single container.Additive fluids from the canister may be placed into the refrigerant circuit of an air conditioning system by (1) connecting the canister to the circuit after it has been emptied and vacuum pressure created therein, (2) connecting the canister to the refrigerant circuit suction line during system operation, or (3) connecting the canister to the suction line with the system off, to thereby force refrigerant from the circuit into the canister, and then starting the system to cause the vacuum pressure in the suction line to draw the contents of the canister into the refrigerant circuit.
