Abstract
PURPOSE: This is the system to be applied on the two stage compression refrigerator incorporated with direct expansion system intercooler, and is to prevent the liquid counterflow phenomenon which is liable to happen at the time to start operation and before the expansion valve of the temperature sensitive tube arrives at a certain temperature. This system also abviates the troubles resulting from the counterflow of the liquid.
