Refrigeration engineers operate and maintain equipment used to control temperature and transfer heat. Their responsibilities involve understanding refrigeration cycles, equipment performance, system controls, refrigerants, maintenance procedures, and operating safety.
The ICC 311-PA-PH examination evaluates refrigeration engineering knowledge through questions involving system components, electrical controls, piping, air distribution, maintenance, and mechanical requirements. Candidates must understand how refrigeration equipment operates and recognize the principles governing safe system performance.
This preparation product focuses on four important references: the 2020 National Electrical Code, 2021 International Mechanical Code, 2021 International Fuel Gas Code, and Modern Refrigeration and Air Conditioning, 22nd Edition.
With three months of practice access, 1 Exam Prep helps candidates reinforce technical knowledge, improve familiarity with important reference materials, and approach refrigeration engineering examination preparation with greater confidence.
The Pennsylvania (Philadelphia) Engineer Grade B examination, identified by ICC code 311-PA-PH, is part of the International Code Council's Contractor/Trades examination program.
The examination covers refrigeration engineering and the technical knowledge associated with operating and maintaining refrigeration machinery.
The official ICC examination outline identifies nine content areas:
Electrical and Controls is the largest examination category, representing 20% of the test. Theory, Terminology, and General Requirements follows at 15%.
The remaining subjects evaluate important refrigeration components, operating procedures, installation requirements, and maintenance practices.
With 180 minutes available for 60 questions, candidates have an average of three minutes per question. Understanding refrigeration principles and navigating technical references efficiently can help improve examination readiness.
The Philadelphia ICC Engineer Grade B 311-PA-PH examination is an open book test.
The examination permits designated reference publications under ICC's testing procedures. The published examination reference list identifies the 2021 International Mechanical Code, 2021 International Fuel Gas Code, 2020 National Electrical Code, and an examination-specified edition of Modern Refrigeration and Air Conditioning.
Open-book testing assesses more than the ability to locate information. Candidates must understand refrigeration systems, identify appropriate code requirements, and apply technical knowledge to practical situations.
For example, an electrical controls question may involve motor circuits or protective equipment, while a refrigeration question may require understanding system pressures, component operation, or heat transfer.
Effective open-book preparation includes:
The Modern Refrigeration and Air Conditioning, 22nd Edition, is a study reference for this product. The ICC examination bulletin identifies a different edition for examination-room use.
Consistent practice with the relevant publications helps candidates identify applicable technical information and strengthen their understanding of refrigeration engineering.
The Philadelphia Department of Licenses and Inspections (L&I) administers Engineer Licenses within the City of Philadelphia.
The Grade B classification applies to refrigeration engineers operating and maintaining refrigeration machinery.
The examination is an important part of the licensing process, but professional qualifications and application documentation are also required.
Philadelphia's Engineer License program recognizes four classifications: Grade A, Grade B, Grade C, and Grade D. Each classification corresponds to different equipment and operating responsibilities.
The Philadelphia Engineer Grade B License is a municipal license regulated by the Philadelphia Department of Licenses and Inspections.
The Grade B classification is specifically designated for refrigeration engineers. It is distinct from the Grade A classification, which covers steam boilers, stationary engineering, and refrigeration engineering.
Philadelphia's published Engineer License requirements include:
Philadelphia requires examination results to reference the current version of the applicable Philadelphia Code and associated standards, or the license application must be submitted within 12 months of successfully completing the examination.
The city adopted the 2021 International Mechanical Code and 2021 International Fuel Gas Code with applicable amendments beginning July 1, 2026.
Grade B refrigeration professionals must also follow relevant mechanical, electrical, fuel gas, and safety requirements governing their equipment and workplace responsibilities.
These publications address complementary areas of refrigeration engineering. The mechanical code establishes mechanical installation requirements, the electrical code supports controls and equipment wiring, and the refrigeration textbook explains equipment operation and underlying technical principles.
The fuel gas code provides additional information about fuel-gas equipment and related mechanical safety requirements.
This product includes online practice questions with three months of access. The publications listed above are study references and are not included as physical books.
