    摘要： An apparatus and method are developed to improve accuracy of diagnostic tests for A/C systems. In particular, a refrigerant recovery unit may have its hoses pre-charged with a refrigerant to a predetermined pressure or amount before performing the diagnostic tests on the A/C system of the vehicle. For example, a predetermine amount of refrigerant may be injected into the hoses of the refrigerant recovery unit to pre-charge them. The pre-charged hoses of the refrigerant recovery unit may prevent a refrigerant flow from the A/C system to the hoses connected thereto before the diagnostic tests are implemented and thus, improve the accuracy of the diagnostic tests.

    摘要： A method and charging apparatus for adding refrigerant to an air conditioning system are provided. The method includes calculating a temperature differential by measuring a first temperature of a refrigerant inside of a refrigerant container and measuring a second temperature either at the air conditioning system or the ambient temperature. The method further includes using the temperature differential to calculate a compensation amount of refrigerant to add to a previously determined recommended amount of refrigerant based on the type of air conditioning system being charged.

    摘要： A refrigerant recovery unit is provided that can clear oil from an oil inject path in order to prepare the unit to switch over to a different kind of oil. The refrigerant recovery unit includes an oil inject circuit that receives an oil from the oil bottle into the refrigerant system. The refrigerant recovery circuit is coupled in fluid communication with the oil inject circuit. The refrigerant recovery circuit is operable to receive and transfer a fluid drawn through the oil inject circuit. A controller is operatively connected to the refrigerant recovery circuit and to the oil inject circuit so that as the fluid is drawn through the oil inject circuit a quantity of the oil in the oil inject circuit is removed.
