Abstract
A method and system for providing a ridethrough reserve for a pulse tube refrigerator (PTR) ( ) includes a pressurized tank ( ) containing a fluid used to provide fluid pressure and auxiliary power to a PTR ( ) during an electrical power supply failure. A pressure regulation valve (pressure valve) ( ) releases the fluid from the pressurized tank ( ) into the PTR ( ). A power regulation valve (power valve) releases from the pressurized tank ( ) a driving gas volume for driving a pneumatic motor ( ). The pneumatic motor ( ) in turn drives a rotary valve ( ) of the PTR ( ). A release valve ( ) releases fluid from the PTR ( ) so as to lower the fluid pressure to a predetermined pressure range and enable fluid oscillation in the PTR ( ).
