Course B (Tour capacity: 40 persons)Keihin Logistic Center, Yamate Reizo Co., Ltd.
Yamate Reizo Corporation operates five logistics centers in Tokyo Bay Area, supporting the cold supplychain in Tokyo metropolitan Area. The Keihin Logistic Center is one of their refrigerated warehouses,with the storage capacity of 77,574 m3. In 2024, they upgraded all refrigeration units from R22 to CO2transcritical booster systems with heat recovery. To prevent the condensation in low temperature loading
room, desiccant dehumidification system using waste heat has been installed. Additionally, water spraydefrosting system using waste heat was used. Energy saving of 25 % can be expected compared to R22
refrigeration system. In the technical tour, participants will have the opportunity to observe CO2refrigeration units and desiccant dehumidification system.

8th IIR-International Conference on Sustainability and the Cold ChainCourse C (Tour capacity: 30 persons)Training Vessel of Tokyo University of Marine Science and Technology “Shin-yo Maru”
In this course, participants will tour the training vessel “Shin-yo Maru” moored at Toyomi Fisheries Pier.
Shin-yo Maru IV which entered service in 2016, is an on-the-job ocean-going training facility for the
next-generation of undergraduate and graduate students. As highly-trained experts being educated withthe modern knowledge and skill in fisheries including trawling, squid jigging and long-line tuna fishing,as well as the qualification in marine-work experts, students will assume an important role in the futureof fisheries and the oceans not only of Japan but of the world.
As the ocean-going research facility, Shin-yo Maru IV is equipped with up-to-date instruments withadvanced capabilities, e.g. underwater structure survey using 2-D seismic reflection profiling system,
the application of an autonomous underwater vehicle, and precise seafloor survey using acoustics.
Being so well equipped, she is capable of conducting leading studies on the oceans including scientificinvestigations on resources and marine life.
Shin-yo Maru IV has a simple, electric-powered propulsion system with a combination of a threephase induction motor and a controllable pitch propeller (CPP) having a reduction gear with a clutch.
In the interests of the redundancy of the ship, a 2-engine 2-propeller shaft system, in which twodevices are installed, is adopted.
Three main generators installed in the engine room can be used as the power source for bothpropulsion and general use on board the ship. Power management and generator eco-mode functions,which automatically control the number of generators at work, are available for the efficient operationof the generators.

Course D (Tour capacity: 30 persons)
Saito Laboratory, School of Fundamental Science and Engineering, Waseda University.
Saito Lab. conducts a wide range of R&D in the field of the refrigeration, air-conditioning and heatpump systems.
For example, we pay attention to the basic research on heat transfer enhancement, frost formation,and refrigerant distribution, and the applied research on the next generation actual dynamic performance
evaluation method of the refrigeration & air-conditioning system that is expected to become ISO
standards in the near future.
In addition, a big national project is underway for the cold chain. Especially we construct aconvenience store in the campus whose surrounding environment is controlled artificially. This store
includes showcases and air-conditioner and so on, and has the energy management system to optimize
whole energy use of the store..
The Lab. tour will include a visit to these facilities.
