Curriculum

Term 1

3 credits
CLD 1013 cr

Refrigeration Fundamentals and Cascade Systems

This course delivers the thermodynamic principles, vapor-compression mechanics, and multi-stage configurations essential for achieving ultra-low temperatures down to $-86^\circ\text{C}$. Students analyze pressure-enthalpy diagrams, evaluate high-stage and low-stage refrigerant interactions, and master diagnostic techniques on dual-circuit cascade systems.

Term 2

6 credits
CLD 1053 cr

Ultra-Low Temperature Freezer Construction and Control Systems

This course examines the specialized structural engineering, insulation technologies, and electronic control architectures utilized in modern ultra-low temperature refrigeration equipment. Students develop practical competence in evaluating thermal barriers, servicing microprocessor and programmable logic controllers, and troubleshooting electrical control loops.

CLD 1103 cr

Cryogenic Backup Systems and Safety in Ultra-Low Temperature Applications

This course provides technicians with specialized knowledge of liquid nitrogen ($LN_2$) and liquid carbon dioxide ($CO_2$) auxiliary refrigeration systems designed to protect ultra-low temperature payloads during mechanical cooling failures. Students master cryogenic thermodynamic principles, emergency backup hardware installation, atmospheric gas monitoring, and critical safety protocols for handling pressurized cryogenic fluids.

Term 3

3 credits
CLD 1153 cr

Cold Chain Temperature Monitoring, Alarm Systems, and Quality Documentation

This course prepares technicians to install, calibrate, and troubleshoot independent temperature monitoring systems, remote telemetry, and multi-stage alarms across ultra-low temperature storage environments. Students develop practical expertise in validating sensor placement, analyzing thermal deviation data, and generating regulatory-compliant audit documentation for critical cold chain assets.
