Abstract
An air conditioning service system includes a refrigerant storage vessel, a charging subsystem fluidly connected to the refrigerant storage vessel and configured to connect to a refrigeration circuit to transfer refrigerant from the refrigerant storage vessel to the refrigeration circuit, a first pressure transducer configured to sense a first pressure in the refrigerant storage vessel, a first valve configured to control a flow of ambient air between the refrigerant storage vessel and the atmosphere, and a controller operably connected to the first pressure transducer and the first valve. The controller includes a memory and a processor configured to execute program instructions stored in the memory to operate the first valve to admit air into the refrigerant storage vessel based on the sensed first pressure, and to operate the charging subsystem to fluidly connect the refrigerant storage vessel to the refrigeration circuit.
