1. A method of maintaining an air conditioning or refrigeration system charged and pressurized with a system fluid comprising a refrigerant, the method comprising: a) introducing into the system fluid, a maintenance fluid containing a hydrolytic drying agent which maintains a fluid form upon hydrolytic reaction with water, and having a maintenance fluid viscosity; andb) causing the system to distribute said maintenance fluid throughout the system fluid,wherein the hydrolytic drying agent is an orthoester, and the orthoester is selected from the group consisting of trimethylorthoformate, trimethylorthoacetate, triethylorthoformate, triethylorthoacetate, triisopropylorthoformate, triisopropylorthoacetate, and triethylorthobenzoate. 2. The method of claim 1 further comprising: c) determining if the system fluid continues to indicate the existence of water in the system, and, if so, then repeating a), b), and c). 3. The method of claim 1 wherein the hydrolytic drying agent forms or maintains an oil-soluble form after reacting with water. 4. The method of claim 1 further comprising passing said hydrolytic drying agent through a filter/dryer comprising a solid catalyst. 5. The method of claim 1 further comprising: c) introducing into the system fluid, at a time after (a) and (b), a sealant fluid comprising a sealant; andd) causing the system to distribute said sealant fluid throughout the system fluid. 6. The method of claim 1 further comprising: c) introducing into the system fluid, simultaneously with (a), a sealant fluid comprising a sealant and having a sealant fluid viscosity;d) causing the system to distribute said sealant fluid throughout the system fluid. 7. A method for injecting sealant into an air conditioning or refrigeration system having a compressor, a high pressure side (“high side”), and a low pressure side (“low-side”), the method comprising: injecting the sealant and a lubricant as a mixture in a quantity to provide sufficient lubrication to maintain proper operation of the compressor when the sealant is fully distributed in the system, while injecting the sealant so as to maintain proper operation of the compressor before the sealant is fully distributed in the system,wherein the mixture further comprises a drying agent, the drying agent comprises an orthoformate, and the orthoformate is selected from the group consisting of trimethylorthoformate, triethylorthoformate, and triisopropylorthoformate. 8. The method of claim 7 wherein the system is a hermetically sealed air conditioning system and injecting the sealant comprises injecting the sealant comprises injecting the sealant in the hermetically sealed air conditioning or refrigeration system. 9. The method of claim 7 wherein the system is a charged air conditioning and refrigeration system and the sealant is injected into the charged system. 10. A device for use in maintaining an air conditioning or refrigeration system, the device comprising: a) a sealed vessel adapted to receive a hose assembly forming, at a proximal end, a sealed fluid connection to a refrigerant fluid of the system, and having at a distal end, a receiving unit for the vessel; andb) in the sealed vessel: (i) a fluid containing a hydrolytic drying agent which maintains a fluid form upon reaction with water, and (ii) a sealant,wherein the hydrolytic drying agent is an orthoester, and the orthoester is selected from the group consisting of trimethylorthoformate, trimethylorthoacetate, triethylorthoformate, triethylorthoacetate, triisopropylorthoformate, triisopropylorthoacetate, and triethylorthobenzoate. 11. The device of claim 10 wherein the hydrolytic drying agent forms or maintains an oil-soluble form after reacting with water. 12. The device of claim 10 wherein the hydrolytic drying agent forms or maintains a form soluble in mineral oil after reacting with water. 13. A device for use in maintaining an air conditioning or refrigeration system, the device comprising: a) a sealed vessel adapted to receive a hose assembly forming, at a proximal end, a sealed fluid connection to a refrigerant fluid of the system, and having at a distal end, a receiving unit for the vessel; andb) in the sealed vessel: a fluid containing a hydrolytic drying agent which maintains a fluid form upon reaction with water,wherein the hydrolytic drying agent is an orthoester, and the orthoester is selected from the group consisting of trimethylorthoformate, trimethylorthoacetate, triethylorthoformate, triethylorthoacetate, triisopropylorthoformate, triisopropylorthoacetate, and triethylorthobenzoate. 14. The device of claim 13 wherein the fluid does not contain a sealant. 15. A kit comprising: the device of claim 5; a hose assembly capable of forming, at a proximal end, a sealed fluid connection between an inside of the hose assembly and a refrigerant fluid in an air conditioning or refrigeration system, and capable of attaching, at a distal end, to the vessel, said distal end capable of puncturing or otherwise opening said vessel to form a fluid connection between the inside of the hose and the fluid; and instructions for attaching the proximal end of the hose assembly to the air conditioning or refrigeration system and for attaching the distal end of the hose assembly to the device.
