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.

摘要： A method of charging or recharging an air conditioning wherein an initial amount of refrigerant is introduced, followed by additional introductions of refrigerant during injection pulses. The pulse periods are adjusted dynamically during the charging/recharging process based on feedback obtained after each pulse related to how much refrigerant was transferred during the previous pulse. Also, a system for implementing the above-mentioned method.

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.
