Program details
The Capstone Project is the culminating stage of the program and brings together all the technical skills you develop. It involves the complete development of an industrial refrigeration plant design, from needs analysis through the O&M proposal, using the professional methods and calculation tools the industry relies on.
The project can focus on food processing, cold chain logistics, retail or industrial processes with refrigeration needs. You will run the heat load study for the selected process or facility, size the refrigeration system to ASHRAE 15, IIAR 2 and ASME codes, select equipment with technical and economic justification, design the machinery room to safety requirements, prepare refrigeration flow diagrams and electrical one-line diagrams, and develop an economic feasibility analysis that includes energy use and return on investment.
The project also covers the control and monitoring system design, the O&M strategy with troubleshooting protocols, and an evaluation of heat recovery options to improve overall efficiency. The final deliverable must meet the technical standard and professional format of a permit submittal package, showing that you can produce complete, rigorous documentation ready for the AHJ or for industrial refrigeration clients.
ICTESS’s Industrial Refrigeration Professional Certificate includes hands-on training with the professional software refrigeration engineering firms use to calculate refrigeration cycles and select components. You will learn to analyze cycles on P-h diagrams, calculate refrigerant thermodynamic properties, run heat load calculations for cold rooms, freezing tunnels and logistics facilities, and select compressors, evaporators and condensers for process conditions. You will work with these tools on real case studies, from defining the refrigeration needs to generating professional technical reports. Specialized refrigeration engineering firms value this practical experience when hiring, because it is the basis for developing construction documents and permit submittals.
An engineering degree is not required, but an associate degree or advanced technical training in refrigeration, HVAC, mechanical or energy is recommended. The program is designed for industrial, mechanical, chemical and energy engineers, and it is also open to HVACR technicians and refrigeration professionals with proven experience at contractors, engineering firms or food companies. You will need prior knowledge of thermodynamics, electricity and reading technical drawings. The program includes advanced refrigeration engineering calculations, so you will need to be comfortable with math, read refrigeration flow diagrams and work with technical calculation software.
The ICTESS Professional Certificate backs your technical specialization in industrial refrigeration and is valued by industry employers as high-level professional development. Although it is not an accredited academic degree, the certificate documents specific, in-demand skills: designing ammonia and transcritical CO2 systems, calculating heat loads, designing machinery rooms to safety codes, and optimizing plant energy efficiency. Refrigeration engineering firms, contractors and plant operators value this hands-on training as a complement to a bachelor’s degree or to credentials such as EPA Section 608 certification, because it shows up-to-date knowledge of codes, natural refrigerants and the projects developed during the program.
The Industrial Refrigeration Professional Certificate stands out for its focus on natural refrigerants and the technical depth of its refrigeration engineering calculations. While many courses cover general refrigeration or a single technology, this program goes deep into ammonia and transcritical CO2 systems, machinery room design and safety, component selection, heat recovery integration and plant energy efficiency.
