摘要： A refrigerant recovery unit is provided and includes a safe purging mode. The safe purging mode allows non-condensable gases to be incrementally purged from a storage tank when the determined ideal vapor pressure is high, such as 40 p.s.i., in order to minimize refrigerant loss during purging. The purging can be done in small increments of time, pressure or mass. The storage tank can include a dip tube that extends into the liquid portion of the refrigerant in order to heat up the refrigerant in the tank with the heated recovered refrigerant.

摘要： A service hose includes a service coupler and a check valve assembly. The service coupler is configured to fluidly connect the service hose to a refrigeration system. The check valve assembly is disposed proximal to the service coupler and includes a recovery and a recharge flow path. The recovery flow path is defined by a flow of a refrigerant from the refrigeration system and flows along a first bore disposed in a body having a recovery poppet. The recharge flow path is defined by a flow of the refrigerant to the refrigeration system and flows along a second bore disposed in the body, a recharge poppet, and a biasing member. The check valve assembly is configured to provide a substantially free flow of refrigerant along the recovery flow path and also configured to provide a predetermined cracking pressure in response to the refrigerant being urged to flow along the recharge flow path.
