A system and method of using a source of low-pressure refrigerant for a cryotherapy procedure. The system may generally include a fluid reservoir and a fluid flow path in thermal exchange with the fluid reservoir, the fluid flow path including a thermal exchange device in thermal exchange with the fluid reservoir, a compressor in fluid communication with the thermal exchange device, a condenser, a reversing valve located between the compressor and the condenser, and an expansion valve located between the condenser and the thermal exchange device. The method may include transferring a low-pressure refrigerant to a first fluid reservoir, reducing the temperature of the refrigerant within the first fluid reservoir, increasing the temperature of the refrigerant within the first fluid reservoir, and transferring the pressurized refrigerant from the first fluid reservoir to a second fluid reservoir.

A compressor assembly includes a compressor of the reciprocating piston type. The compressor includes a cylinder head bounding a cylinder head chamber. Each cylinder head chamber is connected via a condensate drain pipe to a condensate collection chamber so as to form a condensate connection. A first end of the condensate drain pipe is connected with the cylinder head and a second end of the condensate drain pipe is connected with the condensate collection chamber. The first end of the condensate drain pipe is at a highest level of the condensate drain pipe and all other parts of the condensate drain pipe are at lower levels so that transport of condensate through the condensate drain pipe takes place under the effect of gravity.

The disclosure describes various aspects of a vibrationally isolated cryogenic shield for local high-quality vacuum. More specifically, the disclosure describes a cryogenic vacuum system replicated in a small volume in a mostly room temperature ultra-high vacuum (UHV) system by capping the volume with a suspended cryogenic cold finger coated with a high surface area sorption material to produce a localized extreme high vacuum (XHV) or near-XHV region. The system is designed to ensure that all paths from outgassing materials to the control volume, including multiple bounce paths off other warm surfaces, require at least one bounce off of the high surface area sorption material on the cold finger. The outgassing materials can therefore be pumped before reaching the control volume. To minimize vibrations, the cold finger is only loosely, mechanically connected to the rest of the chamber, and the isolated along with the cryogenic system via soft vacuum bellows.

A compressor unit of a cryocooler includes: a compressor motor; an inverter that converts, into drive power of the compressor motor, AC power input to the compressor unit from an external power source; a transformer that converts the AC power into drive power of a cold head of the cryocooler of which a voltage is different from a voltage of the AC power, and a control panel on which the inverter and the transformer are mounted.

A cryopump includes: a cryopump container including a container body defining a cryopump intake port and extending axially and tubularly from the cryopump intake port, and a cryocooler accommodation cylinder connected to a side portion of the container body and extending transversely; a cryocooler fixed to the cryocooler accommodation cylinder and extending transversely within the cryopump container; a plurality of cryopanels thermally coupled to the second cooling stage of the cryocooler, capable of adsorbing a non-condensable gas, and axially arranged between the cryopump intake port and a bottom portion of the container body; and a purge gas inlet installed in the container body below the cryocooler accommodation cylinder to blow a purge gas to a distal portion of at least one of the cryopanels.
