Abstract
A refrigerant recovery unit with improved charging accuracy is provided. In some embodiments, the contamination of charging refrigerant can be prevented while also providing greater refrigerant flow control. In addition, methods associated therewith for servicing refrigerant containing refrigeration systems are provided. In some aspects, the methods include steps that can be used to achieve more accurate assessments of the refrigerant that is charged into the refrigeration systems during servicing.
