第二種冷凍機械責任者 マニアックン

This is an exam preparation app for the Class 2 Refrigeration Machine Operator (2nd Class Refrigeration) certification exam. This is an unofficial app independently created and not affiliated with the exam administering body (it is not approved, endorsed, or supervised). It does not guarantee passing or achieving a high score. The 2nd Class Refrigeration exam consists of three subjects: Laws and Regulations, Safety Management Technology, and Academic Knowledge, each with its own passing criteria. This app aims to help you understand the concepts of heat and pressure, rather than relying on rote memorization. Each topic is presented in sequence: ① Read (Understanding Article) → ② Solve (Multiple Choice Questions) → ③ Return (To the Incorrectly Answered Section) The explanations for the problems indicate "where to return to in the article," allowing you to easily reread the material. ■ Contents - 45 Understanding Articles (1 per topic) - 45 Original Diagrams - 270 Multiple-Choice Practice Questions (120 Laws and Regulations, 90 Safety Management Technology, 60 Academic Knowledge) - 40 Practice Exam Questions (20 Laws and Regulations, 10 Safety Management Technology, 10 Academic Knowledge). The breakdown of questions is the same as a regular exam without exemptions, and questions will be drawn from these 270 (in the app, you solve all three subjects in one go). - Weakness Review (Incorrectly answered questions will be resubmitted the next day, 3 days later, and 7 days later). ■ Free Trial Scope 3 Understanding Articles (1 each from Laws and Regulations, Safety Management Technology, and Academic Knowledge) and 18 Practice Questions are available without purchase. ■ Pricing The app itself is free. Only unlocking all learning materials requires an in-app purchase (one-time payment), and the amount will be displayed on the store's purchase screen. There are no monthly fees. No advertisements are displayed. There are no additional charges. After changing devices or reinstalling, you can resume reading from "Restore Purchases." ■ How the Study Materials Were Created We independently transcribed the materials based solely on the original text of laws and regulations in effect as of the exam reference date (April 1, 2026) (e-Gov Law Search) and primary sources from government ministries and public institutions. We did not use past exam questions, commercially available question sets, or official textbooks. We used AI to create articles, diagrams, and questions (the AI ​​does not operate within the app). Furthermore, we had another AI solve all 270 questions with the answers hidden to ensure there were no discrepancies in the answers, and humans cross-referenced the descriptions with primary sources. The materials were not supervised by qualified professionals or experts. ■ Scope of Coverage • Laws and Regulations: High Pressure Gas Safety Act, its Enforcement Order, Refrigeration Safety Regulations (General High Pressure Gas Safety Regulations for mobile applications, etc.), etc. • Safety Management Technology: Refrigeration cycles, major equipment, refrigerants and brine, safety devices, inspections and responses to abnormalities, etc. • Academic Knowledge: Heat quantity and specific heat, sensible heat and latent heat, specific enthalpy and state point, refrigeration capacity and compression work, coefficient of performance, heat balance, calculation of legal refrigeration capacity, etc. Exclusions: The training and examination itself, work procedures for equipment installation, administrative judgments regarding license applications and appointment notifications Currently Not Covered: Properties of refrigeration oil, thermodynamic physical properties of individual refrigerants, detailed structure of major equipment, generalized fault diagnosis (due to our policy of only including information for which official primary sources have been secured) ■ About the Exam (Information confirmed in the Exam Guide) * The written exam is held annually in early November (November 8, 2026 for the 2026 fiscal year). * 20 questions on laws and regulations (60 minutes) / 10 questions on safety management technology (90 minutes) / 10 questions on academic knowledge (120 minutes) (different time slots for each subject). * The passing score for each subject is approximately 60 percent of the perfect score. * There are no age, educational background, or experience restrictions for taking the exam. * Those who have completed the Type 2 Refrigeration Machinery Training Course can apply for exemption from safety management technology and academic knowledge when applying for the exam (exemption is not automatic). Please check the exam guide of the examination administering body for the latest information. ■ Usability * Study materials are included in the app. You can read them offline while studying. * Study records (answer history, reading status, review list) are saved only on your device. There is no account registration or login. Purchase information is only sent to the server when confirming the purchase. ■ Notes * This is a learning support app that we have independently created. This is not an official study material approved, recommended, or supervised by the examination administering body. * This does not guarantee passing or achieving a score. * The laws and regulations covered are fixed to those in effect as of April 1, 2026. "Maniac-kun" is a series that prioritizes creating a sequential structure that follows principles rather than simply increasing the amount of information. The content is created separately for each qualification, and this Second-Class Refrigeration Machine Operator version has been written from scratch for the three subjects, including academic knowledge.
