Abstract: A method and apparatus for charging a thermostatic system with a condensable fluid. Essential parts of the apparatus are a storage container for the condensable fluid, a metering container and a charging head. The condensable fluid in the storage container exerts a vapor pressure and, with the use of valve means, vaporized fluid is caused to flow to the metering container until a first predetermined pressure is reached. With the use of other valve means vaporized fluid in the metering container is caused to flow through the charging head to the thermostatic system to be charged until a second lower predetermined pressure is reached. A reducing valve is between the storage container and the metering container to effect a superheated condition for the fluid flowing to the metering container.

Abstract: The invention relates to a method and apparatus for charging a thermostatic system with condensible and noncondensible mediums such as Freon and nitrogen. The noncondensible medium is introduced first at a predetermined partial pressure followed by the introduction of a measured quantity of the condensible medium. An aspect of the invention involves a preliminary flushing of the system with nitrogen at the system testing pressure such that not only is the system purged of air but the system is tested at the same time.
