ABSTRACT:
A system for transferring a refrigerant from a first refrigerant vessel having at least one refrigerant port to a second refrigerant vessel having at least one refrigerant port is disclosed. This system includes a condenser, a pump assembly having an inlet and an outlet, and conduits for operatively connecting the condenser and pump assembly to the first and second refrigerant vessel in several configurations. The pump assembly includes two pumps operated by one motor and interconnected to either provide series or parallel pumping. This system may also include a transfer tank interposed between the first and second refrigerant vessels. The transfer tank can be used to condense the vapor phase of the refrigerant removed from the first refrigerant vessel and collect the condensed refrigerant in one configuration, then to transfer the condensed refrigerant to the second refrigerant vessel in an alternate configuration. Methods employing this apparatus for transferring a refrigerant between a first refrigerant vessel and a second refrigerant vessel, optionally via a separate transfer tank, are also disclosed.
