Abstract
An air conditioning service system includes an oil receptacle, a coupling port in fluid communication with the oil receptacle through an oil injection line, a solenoid valve configured to selectively allow the oil to flow from the oil receptacle into the oil injection line, a memory including program instructions stored therein, and a controller operably connected to the solenoid valve and the memory. The controller is configured to execute the program instructions to obtain at least one viscosity signal associated with a viscosity of the oil, obtain a volume signal indicative of an amount of oil to be charged, determine a time period based upon the obtained at least one viscosity signal and the obtained volume signal, control the solenoid valve to an open condition, and control the solenoid valve to a closed condition after the determined time period has passed since opening of the solenoid valve.
