Title:
FREEZING CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2022/201574
Kind Code:
A1
Abstract:
Provided is a freezing circuit capable of stably generating a magnetic field in the coil of a magnetic field generator for a long time. The present invention is provided with a compressor (11), a condenser (12), an expansion valve (13), and an evaporator that are connected by refrigerant piping (10). The evaporator is formed from a coil (14) that is wound in a solenoidal shape with a rectangular cross section and formed with a plurality of through holes (21) through which a refrigerant flows, and generates a magnetic field from the coil (14). This allows the coil (14) to serve as an evaporator and to be efficiently cooled by the refrigerant, thereby stably generating a strong magnetic field for a long time.
