ABSTRACT:
A combination pressure measurement/charging system may include a conduit coupled to a refrigerant can. The conduit may be coupled to a low-pressure side of a refrigerant system. The system may include a valve to control a flow of fluid through the conduit. Thus, a flow of fluid between the refrigerant can and the low-pressure side of the refrigerant system may be controlled using the valve. A first pressure gauge may be in fluid communication with the conduit. The first pressure gauge may be coupled to the low-pressure side of the refrigerant system. The first pressure gauge may be used to operate the valve to control fluid flow through the conduit. A second pressure gauge may be coupled to a high-pressure side of the refrigerant system. The second pressure gauge may be isolated from fluids that flow through the conduit.
