Title:
CONTROL METHOD FOR SELF-POWERED CRYOGEN BASED REFRIGERATION SYSTEM
Document Type and Number:
Japanese Patent JP2003108238
Kind Code:
A
Abstract:
To provide a user-programmable control system to adjust a motor speed in a system with ease of management.
A method of temperature control in a cryogenic system, wherein the system includes cryogenic tank. The method comprises a step of providing a motor speed sensor to determine the motor speed, a step of providing a pressure sensor measures a cryogenic pressure, a step of providing a temperature sensor in conditioned space to measure a temperature within the conditioned space, a step of providing a deprived integral region, and a step of generating an overriding control signal at a proportional-integral-derivative controller when the temperature and the pressure are beyond set points of a temperature and a pressure.
