Abstract
A flushing unit for flushing vapor compressions systems with a flushing agent. The flushing unit includes a pressure relief member to ensure that the reservoir containing the flushing agent is not over-pressurized. In certain embodiments, the flushing unit is adapted to be in communication with a driving fluid or propellant, such as an inert gas or a flushing gas, and with a source of a flushing agent, such as a reservoir. The flushing unit includes a valve that, when opened, causes the driving fluid to flow into the reservoir containing the flushing agent and displace the flushing agent from the reservoir, causing it to ultimately flow into the system being flushed such as via a suitable hand-held injector. In the event the pressure in the reservoir exceeds a predetermined level, a pressure relief valve in the flushing unit is automatically actuated, thereby relieving pressure in the otherwise closed system.
