A manifold for charging a system which when in use cycles a refrigerant between liquid and gaseous states is disclosed. The manifold includes a housing defining a flow passage extending from an inlet to an outlet. Structure is within the housing to define a capillary in parallel communication with a section of the passage. A refrigerant state control valve is connected to the housing. The valve, when in the open position, enables concurrent refrigerant flow through both the section of the passage and the capillary to charge such a system with refrigerant in a liquid state. The valve when in the closed position sufficiently blocks the section of the passage to cause all refrigerant flow to be through the capillary thereby to enable charging such a system with refrigerant in a gaseous state.

Refrigeration manifold

A manifold gauge assembly that combines in a single apparatus the features of a manifold gauge set and the features of a phase change device. The manifold gauge assembly may be utilized for charging both pure liquid refrigerants and blends of liquid refrigerants and still maintain the ability of full porting for vacuum optimization. The invention also comprises a phase change device adapted to be fixedly attached to a manifold.
