Abstract
An applicator for introducing an air conditioning system treatment into an air conditioning system refrigerant flow path. The applicator comprises a reservoir carrying the treatment, the reservoir having first and second caps closing first and second reservoir openings, each of the first and second caps including a hose fitting. First and second hoses are connected between respective first and second valves in the refrigerant flow path and the respective first and the second fittings. A pressure differential between the first and the second valves (a higher pressure at the first valve than at the second valve) forces the treatment from the reservoir through the second hose into the second valve in the refrigerant flow path.
Claims15
An applicator for introducing an air conditioning system treatment into an air conditioning system refrigerant flow path through first and second hoses connected between the refrigerant flow path and the applicator, the flow path further comprising first and second serial valves, the applicator comprising:
- a reservoir carrying the treatment;
- first and second caps closing the reservoir;
- a first and a second fitting within the respective first and second caps;
- wherein the first and the second hoses are connected between the respective first and second valves and the first and the second fittings, and wherein a pressure differential between the first and the second valves forces the treatment from the reservoir through the second hose into the refrigerant flow path.
A method of introducing an air conditioning system treatment in a reservoir into an air conditioning system refrigerant Bow path, the method comprising:
- connecting a first opening in the reservoir to a first end of a first hose;
- connecting a second end of the first hose to a first valve in the refrigerant flow path;
- connecting a second opening in the reservoir to a first end of a second hose;
- connecting a second end of the second hose to a second valve in the refrigerant low path, wherein a pressure at the first valve is greater than a pressure at the second valve;
- and
- opening the first and the second valves to create a higher pressure at the first opening than a pressure at the second opening, wherein a pressure difference forces the treatment from the second opening into the refrigerant flow path.
A method for loading an air conditioning system treatment into an applicator comprising a tubular reservoir, the method comprising:
- positioning the reservoir in a vertical orientation having an upper end above a lower end, the upper end open to the atmosphere and the lower end terminated in a lower end cap having a lower fitting therein;
- attaching a supply hose to the tower fitting;
- injecting treatment into the reservoir through the supply hose, during the injecting process air escapes through the upper end;
- detecting treatment leaving the upper end;
- closing the upper end by attaching an upper end cap thereto;
- removing the supply hose from the lower fitting;
- and
- attaching a tower fitting cap to the lower fitting.
