The internal seminar was held at JATL on 25th March 2025, which was instead of the technical meeting so far. Mr. Shimotani, Senior Manager in charge of the Operations Department, served as the instructor for this year's seminar, entitled “Air Conditioning Basics,” which covered a wide range of topics, including heating and cooling loads and the need for air conditioning, the refrigeration circuit, and the structure and roles of the main components that make up the refrigeration circuit.

Although we test air conditioners on a daily basis and have sufficient knowledge of how to handle the testing equipment, our knowledge of the refrigeration circuit varies from person to person, and we hardly disassemble air conditioners to check the inside, so this seminar was very useful for us to match our level of knowledge.

Air conditioners vary from residential to commercial use, his explanations were easy to understand and centered on illustrations of features and how they work, so JATL's members were able to acquire knowledge that will be useful in the performance test.

Mr. Katsuyuki Sawai, Chairman of the Japan Refrigeration and Air Conditioning Industry Association (JRAIA), visited the Japan Air Conditioning and Refrigeration Testing Laboratory (JATL) on January 27 to inspect the testing facilities. He was accompanied by Mr. Koyama, Chairman of the Policy Council, Mr. Okada, Executive Director, and Mr. Kimura, General Manager of the General Affairs Department from JRAIA, and they were welcomed by Mr. Kishimoto, President of JATL and other members of JATL.

On the day of the visiting, JATL introduced the background of its establishment and the status of its business for FY2024, and shared information with the participants. At the end of the visiting, we had a chance to have a discussion with Chairman Sawai, where each member of JATL introduced their work and Chairman Sawai asked questions about the content of them, making the discussion very meaningful for JATL.
